Warm, humid, and occasionally stormy weather for Friday & the weekend

/ August 19, 2021 at 9:38 PM

We remain in a bit of an active pattern heading into the weekend as disturbances traversing an upper-level trough over the region help to enhance coverage of afternoon thunderstorms. Heat and humidity will continue, with temperatures in the low 90s for Friday and Saturday in particular. Dewpoints remain quite elevated — mid-to-upper 70s will be common, especially after the seabreeze moves inland — and this will keep heat indices in the 100-105° range before thunderstorms break up the party a bit.

Much like we saw Thursday evening, thunderstorms that fire will be capable of producing very heavy rain, a lot of lightning, and likely won’t be moving too terribly much, either. Thus, the risk for isolated flooding events continues. Thunderstorms could become briefly severe where outflow boundaries and cell mergers occur, with wet microbursts a distinct possibility in the strongest storms, but widespread severe weather is not expected. The good news is that it won’t rain all day, but when storms do fire, you’ll want to be headed indoors as they will be prolific lightning producers.

Long story short: Keep your water bottles and rain gear handy, because you’ll need both at times throughout the weekend.
