** Severe Thunderstorm Watch in Effect Until 11 PM **
A strong cold front will push through the region over the next 36 hours, which will likely lead to fairly widespread thunderstorms (some of which may be severe with high winds and hail) late this afternoon into the overnight hours. Cloudy skies and scattered showers will linger on Friday with cooler temperatures; luckily, we're likely to see clearing skies and pleasant conditions for the weekend.Image above: Capitalweather.com photographer Kevin Ambrose took this shot of a storm that moved through northern VA yesterday; storms will likely be both more widespread and potent today.
TodaySticky & stormy?
We'll start out the day with partly sunny skies along with warm and humid conditions and high temperatures between 90-95, with heat indices approaching 100. By mid-afternoon clouds will increase ahead of an approaching cold front; heavy, gusty thunderstorms may develop by late afternoon and continue, sporadically, into the overnight hours. Muggy lows will be in the low 70s.
FridayCloudy with showers
The aforementioned cold front will take its time pushing through the area on Friday; as a result, we'll see mostly cloudy to overcast skies with occasional showers, especially during the first half of the day. Cloud cover will limit high temperatures to near 80 in most spots. Mostly cloudy overnight with a slight chance of a stray shower and cooler lows in the mid to upper 60s.
The WeekendClearing and nicer!
Expect mostly cloudy skies when you wake up Saturday morning, but we should see increasing amounts of sun as the day wears on; expect high temperatures in the low 80s with overnight lows in the low to mid 60s. Mostly sunny skies will prevail on Sunday with continued pleasant temperatures in the low 80s, with low humidity, during the afternoon and in the lower 60s during the overnight hours.
The biggest weather story over the next 36 hours will be the passage of a strong, but rather slow-moving cold front which will bring strong to severe thunderstorms to much of the region from late afternoon today through early morning Friday.
If I were a betting man, I'd say a Severe Thunderstorm Watch
by late afternoon today, with hail and high winds being the most likely impacts. The slow movement of the front will mean cloudy skies and lingering showers will punctuate Friday's weather, but high pressure will move in over the weekend, bringing with it clearing skies and below-normal temperatures and humidity levels for this time of the year.Image above: look for strong to severe storms possible over the next 24 hours; graphic courtesy Accuweather.
