D.C. Storms: Possible severe storms this weekend

The heat has been the headline, but a few strong storms are possible over the weekend too. 


It has been a hot start to July with temperatures well into the 90s each day. Some relief is on the way, though, in the form of a "cold" front that will drop temperatures back into the mid 80s by Monday of next week. I use the word cool in quotations, since I don't think mid 80s constitutes "cool". Although, when comparing it to near 100 degree temperatures, I guess we can make an exception. 

The main point is the front will drop South on Sunday and could provide the region with strong to potentially severe thunderstorms.  There will be a threat for storms late Saturday, but it looks like the threat for severe weather will remain North of D.C.  Sunday; however, could bring some nasty weather.   As Adam Caskey discusses in his video blog (above), we are not anticipating another derecho, but thunderstorms with damaging wind gusts are probable.  Here is a closer look at the thunderstorm risks for Sunday:

Damaging wind gusts to 60mph aren't out of the question and frequent lightning is likely, too, in storms that develop.  The Storm Prediction Center has the MidAtlantic area under a Slight risk for severe storms on Sunday.

With the high heat expected over the weekend, coupled with high humidity, there will be enough energy in the atmosphere to support dangerous thunderstorms.  The front dropping South, from New England, will provide the "lift" we need for storms to develop.  Here's a look at one particular computer model that simulates the surface conditions at 8PM Sunday evening.  Keep in mind this is just a depiction of the conditions at the time.

We don't want to scare you with the threat for severe weather, but rather want to inform you on the possibility of strong storms.  I think it's safe to say we are all a little more sensitive to the severe weather after the Friday, June 29th derecho event.  Be safe and stay tuned to WJLA, News Channel 8, and for all the latest weather information.
