Isolated Evening Showers, Thunderstorms

Small hail, gusty winds a threat

Warm afternoon sunshine, combined with cold air aloft and some upper-level energy, provided enough instability to spark some showers and thunderstorms that are moving through this evening. Some spots will see little or no rain, but some places may experience brief strong storms. Heavier showers or storms could produce small hail and gusty winds. The storm threat should diminish after sunset.

Tonight: Isolated showers and thunderstorms during the early evening, some of which could be briefly strong, should diminish after sunset. After that, we're in for a partly cloudy and cool night, as temperatures drop into the mid 50s in the suburbs and around 60 in D.C. for overnight lows. Winds will be light throughout much of the night.

Tomorrow: On Thursday, we will still be under the influence of a pesky low pressure system stuck in Canada. This means morning sunshine will likely give way to at least partly cloudy afternoon skies. Temperatures may be a little warmer tomorrow than today, as highs reach the upper 70s to low 80s. There is a slight risk of an afternoon shower or thunderstorm, but overall coverage should be less than today.
