DC weather whiplash: Near-90 heat replaced by 40s as powerful cold front moves in

DC Weather Authority: Cold front brings storms, cooler weather after warm Saturday

Enjoy the sunshine while it lasts. Temperatures climb into the low 80s with a warm, springlike feel and just a few clouds through the day. Meteorologist Gwen Tolbart says it’s the pick of the weekend before conditions shift. A strong cold front moves in overnight, bringing increasing clouds, gusty winds and the chance for rain — even a rumble of thunder — into early Sunday.

A sharp weather shift is set to bring a sudden cooldown across the East Coast following an unusual stretch of summer-like heat.
