There is a lot of moisture in the air and that’s causing patch fog in many locations. There is a Dense Fog Advisory in effect until 10am.
There have been several dozen school delays because of the fog. To check those school click here.
The fog is going to dissipate around 10am and we’ll see some sunshine for the afternoon. Temperatures will be a few degrees lower than yesterday but it will still feel uncomfortable. Dew point values again will be in the upper 60′s and lower 70′s thru the holiday weekend.
Yesterday we saw highs in the 90′s and we added another 90 degree day to our summer tally. We still are below normal as far as how many 90 degrees we average in a summer.
The heat and humidity will continue for the holiday weekend. Our jet stream or storm track continues to have a large area of high pressure overhead.
Our jet pattern changes for the end of the weekend/Monday. A cold front will bring much more comfortable conditions Tuesday and Wednesday.
Until then we’ll feel the heat and humidity. It will be dry for Thursday and Friday.
We’ll see several chances for rain on Saturday, Sunday and Monday. We could really use the rain! We’re about an inch below normal for the month.
After several days this summer with below normal temperatures we get another surge just as August comes to an end. Dayton racked up 9 days in the 90′s so far this year and we’ll likely add to that total this week. The normal amount of 90 degree days Dayton sees in a summer is about 14. Last year we had 37 days in the 90′s and in 2004 we didn’t see the mercury climb to 90 once.
As far as rainfall goes – we could really use some and our chances are low this week. So far Dayton has only 1.38″ of rainfall in the bucket and that’s almost an inch below normal. Most of the rain feel in the first 9 days of August. Now this is officially at the Dayton Airport – other locations around the Miami Valley have seen a little more. But just about everyone around the Miami Valley could use a little more rainfall.
It doesn’t look like we have high chances either. We have a few chances Tuesday and Wednesday. The pattern we are under right now will bring us high heat and humidity. Our jet stream or storm track will be moving northward allowing for a huge ridge of high pressure to dominate our pattern.
This patter sticks around until Wednesday. We’ll see a brief break of heat but long range models suggest the heat sticks around through Labor Day.
Humidity values will rise too.
Dew points rise into the middle 60′s Monday and the upper 60′s/70 for Tuesday and Wednesday. This means very uncomfortable conditions through most of the week.
Look for lots of sunshine for Monday and a few clouds Tuesday/Wednesday. There’s a slight chance for a few showers Tuesday and Wednesday as a front tries to sink southward.
The air conditioning will get a work out this week! Hopefully you can either stay inside or head to the pool. Have a wonderful week!
It was beautiful today and it will stay that way for the end of the weekend! Humidity levels are low right now but will rise for much of next week.
Take a look at the dew points around the Midwest. We have comfortable values right now but the shades of green are off to the west. We’ll start to feel more humid beginning Monday.
Many of you have been asking, where is summer? Well even though it’s almost the end of August summer is surging once again. The jet stream or storm track is moving northward and a ridge of high pressure is taking over. This pattern is going to hold strong for much of next week meaning hot and humid for us.
Temperatures will be 8 to 10 degrees above normal. Highs will be near 90 and in the lower 90′s for the first part of next week.
The rest of the weekend will be nice. Look for lots of sunshine and warmer temperatures on Sunday. It will be dry.
High pressure sticks around to start the work week but temperatures will rise along with humidity values. It will still be dry for Monday but it will be hot.
There have been a couple of deadly tornado outbreaks this year in Moore and El Reno Oklahoma. But it has been relatively quiet this summer. I have been looking at some of the statistics and noticed the tornado tally is the lowest since 2005.
Here is a look at the annual trend from the local storm reports. This is from the Storm Prediction Center. This is through August 15th. While I didn’t include the data through 2005 (I didn’t want to clutter the graphic) this year’s number is still lower than those in 2005 as well as the average.
Now keep in mind some of the reports in 2013 – that 715 number – may be adjusted slightly. These are somewhat preliminary reports. Verification is not complete yet, however I do not anticipate the number to change all that much.
The number of tornado deaths is also down. April, May are the biggest months for large and deadly tornadoes and we really didn’t see too many this year.
So what could be causing this lack of tornado activity? Well there are a number of cycles in the atmosphere that we continue to monitor. One is the AMO or Atlantic Multidecadal Oscillation. Right now the AMO is showing warmer waters in the Atlantic. There’s also the PDO or Pacific Decadal Oscillation that shows the waters in the Pacific ocean are a bit cooler. I have also read reports that the solar cycle is turning quiet. These climate signals are just a few things we look at when trying to look at long term forecasts.
Another chilly start this morning! Temperatures are dropping like a rock with clear skies and calm winds thanks to high pressure nearby.
We’re not going to break any records however this is the coolest we’ve been since early June. Yesterday we were below normal and we’ll be below normal yet again today.
Temperatures will be a little warmer today with highs near 75. Our jet stream or storm track still has a dip in it. However the pattern will change and temperatures will begin to warm.
We will see lots of sunshine today but expect a few clouds later this afternoon. If you’re headed to the Dayton Dragons game it will be dry with some sunshine.
If you’re out today enjoying the beautiful weather send us a photo! We received this photo from Marsha Coleman in Beavercreek. Snap your photo and send it to the report!t section of our website wdtn.com
We’ll see a few clouds on Friday but it will be dry. Temperatures slowly rise into the lower then middle 80′s for the weekend and next week.
Well it was a shock to the system as I made it out the door this morning. Temperatures in the upper 40′s and near 50 with low humidity in the beginning of August is not typical. While we are chilly we’re not going to break any records.
These chilly conditions are going to stick around for the next several days with highs running about 8-10 degrees below normal. Our jet stream or storm track is flowing out of the northwest and dipping bringing cooler air into the Miami Valley. The jet stream eventually lifts northward and brings slightly warmer air for the weekend.
No problems at all on the drive home or when you pick the kids up from their first day of school. Lots of sunshine as high pressure is in control.
High pressure heads right overhead and that means lots of sunshine and chilly temperatures to start out Thursday.
Temperatures will continue to be below normal for the next several days but will gradually rise to near normal temperatures for the weekend.
We’re starting off this morning slightly humid with some patchy fog. Much like what we had Monday morning. A cold front is moving through the Miami Valley right now. This will bring less humid air and cooler temperatures for the rest of the day.
Dew points will be falling into the 50′s for the afternoon which means it will be less humid! You can open up the windows and let some of the fresh air in.
If you’re heading to the pool don’t forget the sunscreen. We’ll see mostly sunny skies for the day with temperatures running below normal.
High pressure will head into the Great Lakes and produce lots of sunshine and cooler temperatures for the next several days.
Lows on Thursday morning will be near 50 degrees. A cool start but temperatures will warm up for the weekend.
The high pressure area will keep temperatures running 5-10 degrees below normal for the day.
We started out with some patchy fog this morning and now there’s some sun across the area. Clouds will increase today as a cold front moves toward the Miami Valley.
It will be another warm and humid day out ahead of a cold front. The front will eventually bring us a chance for rain. The best chance of rain will be after 7pm. We’ll see a chance of showers and storms possible throughout the overnight hours.
Once the cold front moves through the area skies become mostly sunny with cooler temperatures and lower humidity.
Temperatures will be near normal or slightly above normal today. However temperatures drop to 5-10 degrees below normal as a high pressure area comes down from Canada.
Not a bad start to the weekend with temperatures running close to average with highs in the lower 80′s. But a weak cool front to the northwest will continue to slowly drift southeast which will give us the chance for a few isolated showers in the afternoon on Sunday, but still warm with highs in the low-mid 80′s. Future Trac showing the chance for a few isolated showers:
Here is a look at our jet stream to our north on Sunday keeping our temperatures warm:
A better chance for rain will come Monday night and into Tuesday as another, stronger cold front approaches the area bringing scattered showers and thunderstorms. Behind that front much cooler temperatures as our jet stream shifts southward with highs only making it into the low 70′s on Wednesday!
So far through the first 9 days of August rainfall amounts are running nearly the same as last year just over 1.3 inches, which is above the 0.86 inch average:
And it looks like we will continue to add to that with chances for showers and thunderstorms on Monday and Tuesday.
If you look up in the sky Saturday-Tuesday morning you will see the Perseids Meteor shower. This meteor shower will peak Sunday night into Monday morning. There will be 50 meteors per hour and with little moonlight you should be able to see these pretty well. However, it looks like there will be some clouds for us overnight which may inhibit the viewing of these meteors for some of us but shouldn’t be too much of an impact.
It’s the end of July and it doesn’t even feel like it! Today’s cool, cloudy and misty day made it seem like it was September not July 31st.
July we saw 7 days in the 90′s with five of these being consecutive days (I’m pretty sure everyone remembers sweating these days!) Twelve days were in the 70′s. Some of these highs were the LOW 70′s. In fact one day we hit a new record low AND on the same day our high temperature was 71 which is a record minimum high temperature.
The final July 2013 summary will come out tomorrow – however I took a sneak peak and it looks like our monthly temperature will be right around normal. Keep in mind we were really hot and really cool so both kind of balance each other out.
So what has been going on and will this pattern continue?
In order to find out why we’ve been so cool we have to turn to our jet stream or storm track. The jet stream has been producing a trough or northwest flow which keeps us cool here in the Miami Valley. This pattern will continue through the middle part of August. Here’s what the jet stream looks like in the beginning of August – I have highlighted the “trough” in the jet stream.
The Climate Prediction Center has issued a below normal temperature forecast for the middle of August. This means the Miami Valley will likely continue to see below normal highs for a couple more weeks.
I know this isn’t what many of you want to hear for the last month of summer. While it may not get really hot it should be warm enough to hit the pool one last time.
Well this day is going to go in the weather history books. Honest question – how many of you turned the heat on in the car this morning? It was a tad chilly and a shock to the system especially in late July!
This morning and afternoon we broke two records. The first – a new record low temperature this morning. The second a record “low” maximum temperature. Basically the coolest high we’ve see on that date.
The reason for the chill in the air is our jet stream or storm track pattern. There’s a dip in the jet stream which means cooler air is taking over the area.
Temperatures are still going to be below normal for Monday but we’ll be a little warmer than Sunday as our jet stream begins to take a more west to east flow.
Clouds begin to break up later tonight. We’ll see a sunny start Monday but it will still be on the cool side but dry.
Our next storm system heads this way for Tuesday. It will bring us a chance of showers after 5pm on Tuesday. There’s also a good chance of rain on Wednesday.
Last week we were talking about a heat wave with highs in the 90′s and now we’ll be in the lower 70′s to end the weekend. The cold front which is just about to move through brought heavy rain to the Miami Valley earlier today. Much of the area picked up at least an inch.
The rain cleared just in time to enjoy a nice afternoon. Behind this front temperatures are going to be well below normal.
Much of Ohio, Indiana and Illinois will be feeling a tad cooler for Sunday. These highs and lows are typical of what we would see in September not late July.
The reason we are feeling these cooler temperatures is because there’s a dip in our jet stream or storm track.
On Monday temperatures do warm a little bit but they’ll still be slightly below normal. By Tuesday we’ll get a little closer to normal when our jet stream takes on a more west to east pattern.
We’ll we are enjoying our temperatures in the 70′s parts of Europe are baking in the 80′s and 90′s.
They have a ridge in the jet stream pattern across the pond. You remember the heat right? If you’re looking for more pool weather – hang tight. We still have August to get through.
Thunderstorms hit the north and central area of the Miami Valley early this morning, bringing heavy rain, strong winds and lots of lightning. There was a 64 mph wind gust in Logan County.
We have also heard from the Miami County Sheriff’s Office that there are tree limbs and power lines down in Troy and Piqua. As of 12:45pm DP&L is reporting around one thousand customers without power mainly in Miami County. We also heard there was a power line down outside of a salon in Greenville.
Heavy rain also fell in a short amount of time which is why a Flood Advisory remains in effect until 2pm for Shelby, Clark, Logan, Miami and Champaign counties.
Here is a look at the current radar image as of 12:45pm. The white line is what’s called an outflow boundary. This gives us a clue that strong winds are just ahead of these thunderstorms.
The rain did provide some temporary relief from the heat. However if we see a little more sunshine this afternoon there could be more thunderstorms that flare up. The Storm Prediction Center has us under a low risk of severe weather this afternoon. We are monitoring the potential for a weather watch. As you can see this would only include the southern sections of the Miami Valley.
We have been getting a few photos through our report!t site and we appreciate them!

These are just a few! Please send them when it is safe to do so. I will be watching the weather for the rest of the afternoon!
I hope you were able to get the lawn mowed today. There were a few spotty showers but most of the area saw dry conditions. As of 6pm there are a few showers north of Dayton that are hitting the northern half of the Miami Valley. So we’ll still see a chance for showers and storms this evening but they will be isolated.
We did see a lot of cloud cover today but by the middle to late afternoon broke into some sunshine. This helped temperatures rise into the upper 70′s and near 80 degrees.
One thing you may have noticed is the humidity. Dew points, which is what we use to measure how much moisture is in the air, are in the middle and upper 60′s.
These are going to remain high through the middle of the week. With readings rising a little more. So keep the AC running. We’ll finally get a break by the end of the week.
We still have an unsettled weather pattern in place for the beginning of the new work week. Temperatures will rise to the middle to upper 80′s Tuesday and Wednesday.
Isolated showers and storms are possible tonight and early Monday morning. There’s a better chance for showers and storms Monday afternoon.
Rain again is possible on Tuesday.
High pressure begins to build across the Miami Valley for the end of the week. This means dry conditions, less humid air and near normal temperatures.
I’ve been on vacation for the past week and kept seeing text messages with flood warnings popping up on my phone. It wasn’t until I was with my family in Kentucky that I saw how much rainfall has fallen. I was along the Ohio River near Owensboro, KY on my Uncle George/Aunt Anna’s boat Wednesday and noticed “the river” was really high. Uncle George had to constantly keep his eyes peeled for tree limb floating in the water. He said that because the river was so high debris started floating in the middle of it. I ended up trying to water ski for the first time – that didn’t go well – but that’s for a different blog
One of our weather checkers Jim Allen in Springboro says he has had five inches of rainfall since Wednesday including 2.5″ since last night. Here’s a photo he sent to us.
There’s a flood warning for portions of the southern half of the area until 7:45pm.
Rainfall amounts for the southern sections of the Miami Valley have totaled near an inch. Here’s a look at Doppler radar estimates. Dayton is already about a half inch above normal for the month with rainfall.
Showers will be scattered tonight and tomorrow as well. It looks like if you want to try and mow the grass there’s a chance you’ll be able to sneak it in early in the morning.
Another round of showers is possible Sunday afternoon and Monday as well.
This unsettled weather pattern continues through much of next week. Keep the umbrella handy and the AC on because it’s going to remain humid and temperatures will rise for the first half of the week.
I hope you had a wonderful weekend! I was able to go to the Vectren Dayton Air Show. It was the first time I have been to an air show without having to work. It was great to sit back, relax and enjoy the show. I was able to talk to with a few of the sky divers from Skytrax in Middletown. They say that they are amateur meteorologists because the weather plays an important role in their jobs
It was hot this weekend and we’re in store for much of the same this week. Just like Saturday and Sunday showers and storms will pop up at the peak heating of the day.
Some of the storms may be on the stronger side with gusty winds, heavy rainfall and lightning. Yesterday’s storms produced some gusty winds and in some locations pretty pictures.
If you have any photos you would like to send to us you can use the report!t feature at wdtn.com or by using the 2News app on your mobile device.
A great day to hit the pool but remember we’ll see more clouds as the afternoon continues with showers and storms possible.
We are in store for a pattern change by the end of the week. Right now our jet stream or storm track is moving from west to east and that means the heat is here for today.
By Friday our jet stream takes a dip right over the Great Lakes and this means temperatures fall into the lower 80′s and humidity values drop. Whooo hooo
Happy Friday and first day off summer! Today summer officially began at 1:04 am. It’s the summer solstice and the longest day of the year.
Summer is here and it feels like it! We’ll see highs in the middle to upper 80′s today. Humidity values won’t be too bad but will rise for the weekend. It’s going to be great to hit the pool today. But don’t forget the sunscreen we have a high UV index.
Highs will be near 90 for the weekend. It’s going to feel more muggy too. So hot and humid for the Vectren Dayton Air Show.
The heat and humidity will stick around not only for the weekend but for the beginning of the work week as well.
There’s a slight chance an isolated shower will pop up thanks to the heat and humidity this weekend. Most of the area will be dry but late in the afternoon/evening a shower may pop up.
This weekend we’ll also see a full moon and it has gained the nickname “supermoon.” The moon orbits the Earth in an ellipse which means there are times the moon is far away from the Earth and close to the Earth. This time it’s close and is called the perigee.
If you have weather photos of the moon or of any activity you are doing this first day off summer send them to report!t. Have a great weekend!
Showers and even a few thunderstorms are going to end out the weekend just in time for Father’s Day. Hopefully you enjoyed Saturday with the sunshine we saw earlier today. We made it into the 80′s and that trend will continue for the next few days.
There are a few showers popping on Live Doppler 2HD right now and they will continue to be scattered overnight as well. There’s another chance for rain on Father’s Day as a cold front that is off to our west moves east Sunday.
While Father’s Day won’t be a complete wash out there will be on and off showers throughout the day. If you have any outdoor plans the best chance of squeezing those in would be later in the afternoon/early evening hours.
Showers will come and go in waves late tonight and throughout the day tomorrow. Here’s a look at our Futuretrac forecast model. We’ll see one wave of showers around midnight then another one around 7/8am Sunday.
We’ll get a bit of a break before another round of showers pushes through around noon.
As the afternoon wears on the chance of showers diminishes and the coverage becomes more scattered.
On Monday there’s still a slight chance for a few showers but they will be widely scattered.
The storms that moved through late Wednesday night and early Thursday morning did produce two very weak tornadoes in the northern part of the Miami Valley. Two EF-0 tornadoes hit Mercer and Augalize counties.

Today was a great day for a BBQ!!! I met up with some great friends from twitter and we went to Eastwood Metropark for some fun and great eats. Jamie Jarosik was there too and snapped this photo.
Big thanks to Shane for taking care of chef duties. The rain held off and the weather was just right. It wasn’t too hot or too cold thanks to cloudy skies. We did see some sun at times but the clouds really helped to keep it comfortable.
Right now we’re seeing some showers across portions of the area. Here’s a look at the radar at 6pm
This batch is light and moving from the south to the north. There’s another line of showers off to our west that will eventually head this way overnight.
Here’s what it looks like will happen. Right now the light rain will move northward, we’ll get a break and then we’ll see another round of rain overnight through the Monday morning commute. As the day wears on Monday rain becomes much more scattered. Here’s what I am thinking:
Temperatures will be a touch cooler Monday due to the cloudy skies and rainfall. Today despite the clouds we did make it up to 82.
Keep the umbrella handy for Monday morning and through the early part of the afternoon.
By Monday evening for the drive home it looks much better.
Tuesday looks great with mostly sunny skies and highs in the lower 80′s.
The sunny skies won’t last long there’s another chance for some showers Wednesday night. We’ll continue to track the chance of rain for the middle of the week.
