Warm and humid with thunderstorms…

July 9th, 2013 at 8:28 am by under Weather

Dew points are in the 70s this morning… what does that mean to you?  It is pretty uncomfortable outside– feeling quite humid.  This is a very sticky airmass in place across the region:

With the high moisture content, the potential for heavy rain will continue as upper level energy continues to move through the Miami Valley at times.   Pretty much at any time today, there could be a shower or thunderstorm in the area.  BUT they will be scattered about, so there will be a good deal of dry weather today as well.  It will be warm, with near-normal temperatures in the mid-80s.

With all the active weather we’ve had, rainfall amounts at the airport are sitting right above normal values for the month, although still below for the year:

HOWEVER… some local communities have seen their entire average monthly rainfall… and it’s only the 9th of the month!!  We’ve had localized flooding at times in many parts of the Miami Valley over the past week or so.  The ground is saturated, and when rainfall rates are intense… there is nowhere for all that water to go… so it becomes “runoff” and flash flooding is likely.  The chance for this continues today, so remember the phrase, “Turn around, don’t drown”… as we remind you to NOT travel across water-covered roads.  You don’t know how deep the water is… and you don’t know the condition of the road under the water.  It may be damaged and/or washed out completely.

Wednesday looks like more of the same… warm and humid with scattered thunderstorms.  We will likely see better storm coverage in the area, as a cold front approaches and moves through at night.  Some of these storms could be strong to severe, and the SPC does have us in an Elevated Risk for severe weather.  Then… FINALLY… a break from the rain chances.  It will be nice to see an all-dry forecast for awhile.  Humidity drops, too, as we dry out Thursday right through the weekend.  Can I get an “Aaaahhhhhh!”  ??
