Extreme heat warnings remain in effect across Maryland until 9 p.m. Saturday, with heat index values above 110 and a third straight day of triple-digit highs.
Most of Central Maryland faces an enhanced storm risk — 3 out of 5 — Saturday afternoon and evening, with storms expected after 3-4 p.m. and threats centered on damaging wind gusts and heavy rain.
Saturday night fireworks could still see showers or a stray thunderstorm, while conditions on the water stay hot and muggy and any storm could quickly kick up winds.
Sunday turns cooler but brings more widespread storms, extending a weather alert weekend after the heat dome already drove record temperatures and severe weather around the Washington-Baltimore region.
