A major drop in temperatures will follow a possible thunderstorm Saturday afternoon, following one of the warmest starts to October on record in the D.C. region.
A cold front will reach the Interstate 95 corridor early in the afternoon, bringing gusty winds and the risk of an isolated strong-to-severe thunderstorm to the D.C. area, according to NBC Washington meteorologist Chuck Bell.
The National Weather Service said “damaging wind gusts” could accompany the cold front.

Bell forecasts the timing for the severe weather threat to be between 10 a.m. and 3 p.m. along Interstate 81, between noon and 4 p.m. along I-95 and between 2 p.m. and 6 p.m. in Southern Maryland and the Northern Neck of Virginia.
Southwest winds ahead of the cold front will push temperatures to around 80, followed by much colder and drier air. Bell said he expects rain will come to a quick end tonight and skies will clear in the overnight.
Bell said there’s an 80% chance of rain Saturday and temperatures will reach highs in the mid 70s to low 80s, before falling to lows in the 40s and 50s tonight.
