Dangerously cold air hangs around…

January 8th, 2015 at 10:03 am by under Weather

Arctic air remains in place, as we try to get through the coldest morning of the week! Low temperatures dipped well below zero… down to -7 in Dayton, but it felt a lot colder! Wind chills were running between -25 and -30… which are dangerous levels. At -20, it only takes about 30 minutes for frostbite to set in.

We’ll see double-digits for highs today, but will remain well below normal. Highs will top out near 12-degrees this afternoon, with breezy southerly winds it will still feel sub-zero. A storm system approaches this evening, so temperatures will actually hold fairly steady overnight, only dropping to around 10-degrees.

This system brings in scattered snow showers late this evening through early Friday morning:

forecast

Accumulation looks light–some could see an inch or so. There is the slight chance that our northern counties get a little more than that, and the southern counties a little less. Behind the front, cold air will once again push in, so highs Friday won’t climb very much. We will be up near 12-degrees, and again dip below 0 by Saturday morning!

The good/bad news is that we will warm up a little Sunday into the start of next week… BUT as moisture returns, we could see a messy wintry mix Sunday night into Monday.

Snow tapers; Arctic blast moves in…

January 6th, 2015 at 9:50 am by under Weather

As expected, accumulating snow impacted the Miami Valley overnight and right through the morning commute today. We forecasted 3-5″ of snow by sunrise, and that is what many saw… with some isolated higher amounts:

snow

The snow will gradually wind down across the area through the rest of the morning. The afternoon will be mostly cloudy, and cold. Winds will also increase, so blowing and drifting of our light, fluffy snow will occur. Keep this in mind if out traveling. Some of the treated roads may become snow-covered again!

Colder air will move in behind this storm system, too:

temps

So if the kids want to get out and play in the snow… today is their best bet! Tonight we will drop off quickly, and end up with the coldest readings of the season so far:

LOWS

And as the winds will stay up, it will feel even colder. If the kids have to head back to school tomorrow, make sure they are dressed for bone-chilling cold:

event

High temperatures Wednesday afternoon will only reach 10-degrees! And we could even see a few snow showers in the afternoon. Any accumulation will be light. The cold reaches it’s peak Wednesday night, as temperatures tank to -6, with wind chills at or below -15. Try to stay warm!

A cold, sunny start to the week, but accumulating snow tonight…

January 5th, 2015 at 10:17 am by under Weather

An Arctic high is keeping us cold and dry this morning:

temps

Wind chill have been sub-zero… and this is something that will continue through the day, with breezy conditions and highs only reaching near 18-degrees. A fast-moving storm system will roll in tonight, bringing a good chance of accumulating snow to the area. The timing of steady (and at times, heavy) snow will be between 11pm tonight and 11am Tuesday. You can see how it overspreads the entire Miami Valley on our Futuretrac forecast model:

forecast

We do expect to see a shovelable snow out of this system! There is still some question on the exact track, so stay tuned… but as of this morning here is our thinking:

snow

Chief Meteorologist Brian Davis will have an update in our 90-minutes of news beginning at 5pm on @WDTN Ch2. Just keep in mind there could be school delays… or even closings… on Tuesday. And if snow wasn’t enough, get ready for the COLDEST air of the season this week! Wednesday and Thursday won’t see highs climb very far above 10-degrees… and morning lows will be in the single digits, and even sub-zero. Wind chills will be as cold as -10 to -15°, which could also prompt school delays. Winter is back!

Occasional showers tonight, then a change for Sunday…

January 3rd, 2015 at 9:05 pm by under Weather

A strong area of low pressure brought the steady (and at times, heavy) rain to the Miami Valley Saturday. Many spots received between 1″-2″ of rain, and we still have showers in the forecast overnight:

RAINFALL

The good news, the activity that will affect us overnight is not as steady or heavy–it’s more on and off. Temperatures have really warmed ahead of the main storm, and most are still sitting in the 50s this evening:

temps

We will likely see temps hold steady through the overnight, and then bottom out early tomorrow morning around 45-degrees. That means, there’s no threat of any ice tonight! But we will be turning COLDER on Sunday, as the winds pick up. Get ready for a blustery day, with falling temperatures:

HOUR BY HOUR

As the cold air marches on in, we will see showers change from rain to snow showers. The transition is most likely to occur in the mid-to-late afternoon. Accumulation, if any, will be very light… under a half-inch. But Sunday night slick spots will be possible as temperatures tank! A COLD BLAST settles in for much of next week. We will be running well below normal–many days will only see highs in the teens, and lows drop into the single digits. There is a clipper system to watch for Monday night and Tuesday… this could bring us a quick snow accumulation. The morning commute Tuesday may be impacted, so stay tuned!

Quiet weather today, but a wild weather ride this weekend…

January 2nd, 2015 at 9:09 am by under Weather

The high that brought us a cold, but clear, finish to 2014 is moving away from the Miami Valley today. We have a southerly flow that has developed… so that means a warming trend as we head into the weekend.

temps

Today, temperatures will be fairly close to normal, with highs in the mid-to-upper 30s. The flow strengthens Saturday, ahead of the next storm system currently to our southwest:

satrad

The leading edge of moisture from that system will move in late tonight. As it does, surface temperatures will be at or just below freezing, so we could see a brief period of freezing rain. The timing looks like a window between 3 and 6am:

forecast

So if you will be traveling around this time, be sure you are aware that some areas could be slick. We will quickly warm above freezing through the rest of the morning from south to north. And temperatures will soar in the afternoon! Highs climb into the lower 50s, but we will be dealing with periods of rain, so it will be difficult to get out and enjoy the warm-up. We do expect a good soaking for the area, as most models give us between 1 and 2 inches of rain. With a cold front crossing the area Saturday night, we can’t rule out a rumble or two of thunder, and very windy conditions.

Sunday will start off with a few rain showers in the morning, with temperatures dropping as we head through the day, and rain changing to snow showers. It will still be windy, so expect a blustery end to the weekend! And next week… the coldest air of the season is poised to dive right into the Miami Valley!

Cold Blast

Get ready for real Arctic air!

Arctic air for NYE and NYD…

December 31st, 2014 at 9:30 am by under Weather

Aaaaand the Arctic air is here! We are not in the coldest part of the airmass, as temperatures in the central part of the country are sub-zero… but we are running about 8 to 12 degrees below normal. Here is a look at our morning low temps:

LOWS

Wind chills have been ranging between 2 and 6 degrees this morning. During the afternoon, we will enjoy sunshine, but it will still be very cold. Highs near 23, and wind chills will still be in the single digits at times as winds increase a bit.

Tonight looks cold and breezy for new year’s eve! Temps will fall back into the teens this evening, and wind chills will remain in the single digits to near zero.

It will be another cold one for New Year’s Day. Winds stay up between 10 and 20mph, so it will be cold and breezy. Highs will climb up near 29, but it will feel even colder with the wind. Friday and Saturday will be the warmest of the next week or so. Highs will push into the upper 30s/lower 40s. BUT the chance for showers will also be increasing as the next storm moves in. There is the chance of some mixed precip or freezing rain on Saturday morning… but we will quickly warm and change over to rain in the afternoon:

sat

As the storm moves over the region, colder air will be pulled into the Miami Valley. Sunday will start with the chance of a mix in the morning… changing over to snow showers through the rest of the day:

sun

So it’s a warmer/wet start to the weekend… and it ends colder/snowy. Then temps are back below normal for at least the first half of next week.

Have a safe and happy new year!

Sun this week, but gradually getting colder…

December 29th, 2014 at 8:45 am by under Weather

A strong area of high pressure building in from Canada will bring a cold blast to the country this week! You can see the Arctic air already in place in the Northern Plains this morning… temps well below zero:

temps

Thankfully, we won’t get quite THAT cold here in the Miami Valley. We will just be on the edge of the REALLY cold air:

Cold Blast

Today, highs will be near normal, but tomorrow we’ll drop a little… and then even more so for New Year’s Eve and New Year’s Day:

Trend

We will at least get to enjoy the sun each day, with the high in control. BUT if you’re heading out to ring in the new year, be prepared for a very cold night!

Holiday

At least it will be dry, so we won’t have to worry about wintry precipitation to make the roads bad. Then, warmer air will be pulled into the Miami Valley as a storm system moves in from the southwest over the weekend. There is still some question on track and timing of this feature, but it does look to bring the potential of rain or snow to the Miami Valley in the Friday through Monday time frame! Stay tuned!

Windy & rainy w/some flakes possible tonight!

December 24th, 2014 at 6:46 am by under Weather

We are starting off this Christmas Eve quite mild, with temperatures in the 50s!

temps

It won’t be like this all day, however. A strong area of low pressure to our southwest will lift northeast, and help to bring a cold front through the region:

temps2

This will mean showers, windy conditions, and colder air spilling in late in the day. We do have a Wind Advisory in effect for all the Miami Valley this afternoon into tonight, as winds could gust as high as 45-50mph. So keep an eye on those outdoor Christmas decorations!

wind

Rain is most likely later this afternoon and evening, and then as the colder air moves in we may see a mix/change over to snow:

forecast

A few snow showers will be around tonight and Christmas morning, but any accumulation will be light–maybe a dusting in spots. It will be a chilly holiday, with breezy conditions and highs almost 20-degrees lower than today!

highs

But we’ll see recovery with highs back in the 40s on Friday and Saturday. In fact, Friday will be the nicest day of the  next week or so, with some sun to go along with the 40s!

Merry Christmas!!

Cloudy weekend and our chances for a White Christmas

December 20th, 2014 at 6:28 pm by under Weather

Today we saw another cloudy day.  A thick deck of clouds has been pretty persistent over the last few days and today was no exception.  We haven’t seen the sunshine for several days this month.

CLOUDY DAYS

Take a look at this video The National Weather Service in Wilmington put together click here.  It really shows the cloudy days all this month.

Despite the clouds we saw temperatures today into the 30′s.

almanac

Tomorrow is the first day of winter.  The winter solstice is when the sun’s rays are directed at the Tropic of Capricorn.  This means it’s the first day of winter for us but the first day of summer in the Southern Hemisphere.

WINTER SOL 2WINTER SOL 1

There’s a chance we may see a few peeks of sun for the first day of winter.  If we do it’s going to be short lived…we’re tracking a storm system that will bring more clouds next week.

SUN 8A SUN 6P

Temperatures begin to warm up Monday with highs in the middle 40′s.  We’ll see more clouds, breezy southwest winds and a chance for a few showers later in the afternoon and evening.

MON 8A MON 7P

Looking ahead to Christmas:  There’s a storm system that will form and strengthen over the Great Lakes.  Tuesday we’ll be warm with highs in the lower 50′s and rain likely.  By Wednesday we’ll see rain changing to snow as colder air moves into the area.  Winds begin to pick up out of the west and northwest.  There’s a chance for a few flurries on Thursday too.

CHRISTMAS STORM

While I know many people are wondering if we’re going to see a White Christmas I want to point out we’re not going to see a lot of accumulating snow from this system.  We WILL see VERY windy conditions.  This means what snow that does fall may blow and drift.

This is the way it looks like right now but we’ll continue to monitor it all week long for you.  We’ll have updates on-air and online at wdtn.com

Cloudy, chilly with a few flurries

December 18th, 2014 at 5:43 am by under Weather

Today will be much like yesterday….cloudy and cool.  Temperatures will stay in the lower 30′s.  Clouds will stick around and there’s a slight chance for a few flurries this afternoon.  The best chance will be after 2 p.m.

rain percentage

There’s a storm system producing snow to the west of us in Missouri, and western Illinois.  It will weaken as it moves eastward.

thu 8athu 2p

thu 11p

We’ll have another cold start Friday morning with temperatures in the 20′s but for the afternoon clouds will clear.  Look for some sunshine during the afternoon.

Fri 7aFri 12p

We’re keeping an eye on a storm system that will head this way next week.  At first we’ll see warmer temperatures move this way which means rain.  However the colder air will filter into the area behind the storm and it will turn colder, windy and we may see some snow.  It all depends on the track of the storm and when the cold air arrives…BUT there’s a a chance we could have a White Christmas.  So you’re saying there’s a chance?  YES I’m saying there’s a chance.

Stay warm!

Chilly air mass in place

December 17th, 2014 at 6:08 am by under Weather

Well we have quite a difference this morning than yesterday morning.  Yesterday we were in the 40′s and today we’re right around freezing. Much of us are seeing temperatures 15 to 20 degrees cooler today than yesterday.

We’re seeing gusty winds out of the west.  Wind chill values are in the 20′s.   wind chills

There is a few flurries and a few pockets of drizzle.  Due to the temperature around freezing there may be some slick spots on area roadways.

Foggy start, mild with showers later

December 15th, 2014 at 6:22 am by under Weather

We’re seeing a few school districts operating on a two hour delay due fog.  You can find the latest closings by clicking here.

Visibilities are down to a quarter of a mile north and east of Dayton.

We’re tracking an area of low pressure heading this way later today.  We’re going to see temperatures above normal ahead of the storm.

Our jet stream or storm track will bring winds out of the southwest in the upper levels of the atmosphere today and the switch to the northwest once the low passes us.  This means above normal temperatures at first then near normal for Wednesday through Friday.

As the storm system approaches we’re going to see a chance for showers. Much of the day will be dry but we’ll see a chance for showers later this evening.

The return of sunshine for the second half of the week!

December 11th, 2014 at 6:38 am by under Weather

High pressure building into the region has helped to clear the skies out overnight:

satellite

With the clear skies, temperatures have dropped into the 20s. Even though it’s the coldest morning of the week so far, these readings are pretty close to normal for this time of year:

temps

There is a westerly wind, making it feel even colder… wind chills are in the teens! This afternoon, we will finally… FINALLY… enjoy some sunshine. Temperatures will be seasonably chilly, with highs in the upper 30s. The high moves right over us on Friday, so we should be close to full sun, and we’ll even be a little warmer, with highs in the lower 40s.

Over the weekend, a strong upper level ridge will build into the region, continuing our warm-up:

upper

There will be some low level moisture streaming northward, and this may lead to an increase in cloud cover Sunday and Monday–even some light precipitation. BUT we still should see highs top out in the upper 40s to near 50-degrees!

With the warm-up coming… 2News Today anchor, @WDTNBrooke says it has been difficult for her to get into the holiday spirit. So let’s look at the chances of having a white Christmas:

Stats    Snow Chance

Unfortunately, our two-week temperature outlook is for warmer-than-normal conditions, so it’s not looking good for snow on or around the holiday.

More light precip today, then a quiet stretch…

December 9th, 2014 at 8:16 am by under Weather

A cold front moved through the Miami Valley this morning, and has brought light precipitation to the area:

temps     satrad

We will spend the day with more gray skies in the region, as clouds again dominate. The chance for a sprinkle or a flurry will also linger through tonight. We do not expect any snow accumulation during this time, but colder air is moving in, so we will drop below freezing tonight for the first time in a couple days:

LOWS

Watch for some isolated slick spots late tonight and early Wednesday morning. We will run just below normal, with chilly conditions Wednesday and Thursday afternoons. Highs will be in the mid-upper 30s. The chill doesn’t last too long, we will swing up in the other direction by the end of the week! Friday through early next week, highs will be back in the mid-upper 40s. And we do expect a nice stretch of dry weather to go along with it the warm-up!

Above normal for one day then turning chilly…

December 8th, 2014 at 9:06 am by under Weather

It was sure nice to see the sun yesterday! With highs near normal, it ended up being a really nice finish to the weekend. Clouds moved in late day, and continued to thicken overnight. We won’t see as much sun today as on Sunday, but most of the day will be dry. We then await the approach of this cold front:

satrad

You can see showers along the front to the west… those will work into the area later today into tonight. Initially, it will be the chance for rain showers, but as colder air moves in, we will see the potential for some mixed precip tonight (rain, freezing rain, snow):

forecast

Lows will dip to right around freezing, so we don’t expect much accumulation or a huge icing issue. We may, however, see a few slick spots develop late tonight into Tuesday morning. And the chance of a rain or especially snow shower will continue through Tuesday afternoon. After today, a majority of this week will be chilly, with highs in the mid-upper 30s for a few days:

But there are signs of a nice weekend ahead!

Tracking a cold front for Monday and Tuesday

Rain has ended; dry for the rest of the weekend

December 6th, 2014 at 6:13 pm by under Weather

It was a wet Friday and first start of Saturday.  Many areas picked up one to two inches of rainfall.

Here’s a look at the Doppler radar estimates for the last 24 hours.

Rainfall amounts almanac

The rain is off to the east of us right now.  We still have some  clouds around the Miami Valley but skies will continue to clear through the evening.

There may be a little precipitation lingering when the cold air arrives late Monday and early Tuesday morning.  This cold air may change the rain showers over to a few flurries early Tuesday morning.  Right now it doesn’t look like a big snow at all.

A soggy finish to the week…

December 5th, 2014 at 9:20 am by under Weather

We’ve been dealing with fog and a few light showers across the southern half of the Miami Valley this morning. Roads are just wet, as temperatures are thankfully above freezing:

Temps

That warm front lifts north as an area of low pressure heads our way today. That means the rain will fill in over the region, and fall steady this afternoon, evening and overnight:

forecast    forecast 2

Some of the heavier downpours will occur tonight, as an area of low pressure moves in. Most locations will pick up at least an inch–if not more–through Saturday morning. The rain will begin to decrease in coverage as we head through noon Saturday. That is when winds will shift in from the north… and temperatures will slowly drop:

forecast 3

We’ll see an early seasonable high in the lower 40s, and then drop into the 30s during the afternoon. There will also be a wind chill to deal with most of the day, and it will feel like we’re in the 20s. We end the weekend on a dry note, with partly sunny skies and highs in the lower 40s on Sunday.

Spotty showers later today, then rain to end the week…

December 4th, 2014 at 7:39 am by under Weather

High pressure right over us this morning is keeping us dry and calm as we start the day with some frost:

Temps

We have lots of clouds overhead again, and during the afternoon, we’ll see a scattered showers move in from the southwest. Right now they’re located in Illinois, Indiana and Kentucky:

SATRAD

The southern half of the Miami Valley will have the best chance at seeing rain today. A better chance of an area-wide soaking rain tomorrow will arrive in the afternoon. It looks like rain will fall steady at times, and continue through Friday night into Saturday morning. Most forecast models give us over an inch of rain:

For the weekend, we will dry out Saturday afternoon, and experience near-normal temperatures with highs in the lower 40s. Sunday will be a dry and seasonable day!

Chilly for a couple days, then temps come up a bit

December 3rd, 2014 at 9:48 am by under Weather

We have morning clouds, fog and even drizzle and flurries to deal with. It’s another gloomy start here in the Miami Valley:

troy     beavercreek

Most of today, we will deal with clouds. There is a chance (but not a guarantee!) that they will break in spots this afternoon. We should see highs climb up near 40-degrees… so a little warmer than yesterday. There is another push of cold air behind a front to our northwest:

Temps

That arrives later today, and keeps us cold tonight as we drop into the 20s. Tomorrow afternoon will also feature below-normal temperatures, with a high near 38. Unfortunately, the clouds thicken back up on Thursday, and we can’t rule out a spotty shower late in the day. A really decent chance for rain is back on Friday, with showers likely in a good portion of the Miami Valley. Rain chances remain high for the first part of the weekend. Temperatures during this time frame will actually be a bit above normal, as we experience highs in the mid-40s. This could be the start of something–the extended outlook for the month of December is warmer-than-normal:

trend

And the precipitation outlook for December is an “Equal Chance” at being above/below normal… so not a clear picture at this point!

Have a good day!
