A cold front pushing east is expected to trigger severe thunderstorms across the DMV this afternoon
The Washington DC region is heading into a stormy Today after enduring one of the most oppressive stretches of heat and humidity in recent memory. A cold front moving in from the west is expected to collide with unstable tropical air still sitting over the DMV, producing conditions ripe for strong to severe thunderstorms from late afternoon through late evening.
Both the DC News Now and CBS Baltimore weather teams have designated Today a First Alert Weather Day, reflecting the elevated risk across the DC region. The Storm Prediction Center has placed the entire DMV under a slight risk, rated 2 out of 5, for severe weather.
What forecasters are watching
The main concern going into the afternoon is damaging winds, with gusts potentially reaching 60 mph in the strongest cells. Forecasters say frequent lightning, heavy downpours, and large hail are also possible. An isolated tornado cannot be ruled out, though the primary threat remains straight-line wind damage.
Temperatures SToday will climb into the lower to mid 90s before storms arrive, with breezy southerly winds keeping humidity elevated throughout the morning and early afternoon. Heat index values could push well above 100 degrees ahead of the storms, making the hours before the front arrives uncomfortable and potentially dangerous for anyone spending extended time outdoors.
Timing matters for Today’s plans
Storms are expected to develop first in the western counties of DC around midday, pushing east through the afternoon. The Beltway area is expected to see the most active weather between roughly 3 p.m. and midnight. The cold front should clear the coast before dawn Monday, bringing a noticeable drop in humidity overnight.
Anyone with outdoor plans This evening should monitor conditions closely and have a way to receive weather alerts. The window for severe weather is wide, and conditions could change quickly once the front begins moving through.
What the rest of the week looks like
The relief after Today will be real. Monday brings partly cloudy skies, breezy northwest winds, and highs in the upper 70s to lower 80s. Humidity drops sharply behind the front, and conditions remain comfortable into Tuesday before heat and moisture gradually return by midweek.
Wednesday carries a slight chance of an isolated morning shower, with highs climbing back into the mid to upper 80s. Thursday brings another round of concern, with forecasters tracking a second cold front that could produce another line of strong to severe storms. Highs that day are expected to reach the lower to mid 90s again, with gusty winds ahead of the system.
Friday, which falls on Juneteenth, carries a chance of spotty storms and breezy conditions, with highs in the lower to mid 80s. The following Saturday looks more settled, with partly sunny skies and temperatures back in the 80s.
How the pattern got here
The heat that built up over the past several days was driven by an atmospheric block that trapped a tropical air mass along the East Coast. High pressure overhead prevented any meaningful relief from reaching the region, allowing heat index values to climb as high as 105 degrees Friday before severe thunderstorm warnings were issued across DC, Arlington, and Alexandria.
Friday’s storms swept through much of the region, affecting nearly 1.5 million people in the warning zones. That system cleared before Saturday morning, producing the dry and comfortable conditions most of the area experienced Saturday. Today’s setup is similar in structure but arrives with more organized storm potential, according to local meteorologists.
The pattern should break meaningfully by early next week, but the relief is expected to be temporary.
