As if Monday’s powerful storms weren’t enough, more potentially dangerous weather is in store for Tuesday afternoon.
High pressure off the Carolina coast will continue to pump heat and humidity into the D.C. region, setting up a daily pattern that looks to hold through the end of the week: Highs in the 90s with heat indexes near 100, punctuated with afternoon storms — some of which could be severe.
“If you will be beating the heat at the pool, lake or bay, keep a weather eye on the sky after 3 p.m. for storm development,” Storm Team4 meteorologist Chuck Bell said.
“Damaging wind gusts, lightning and periods of blinding rain are likely in this pattern and everyone should get rained on at least once or twice this week.”

Storms remain in the forecast every afternoon and evening until Saturday, when a cold front will move into the region. Sunday looks to finally usher in a cooler and drier pattern, with highs staying in the mid 80s into next week.
Despite the heat and humidity, Tuesday’s air quality forecast from the Metropolitan Washington Council of Government only calls for a code yellow health concern.
“Air quality may pose a moderate health risk, especially for those who are unusually sensitive to air pollution,” COG said.
Monday’s storms brought torrential rain to parts of Montgomery and Prince George’s counties in Maryland, prompting a Flash Flood Warning.
High water led to lane closures on the Capital Beltway’s Outer Loop near the Interstate 95 interchange; wires and trees were reported down in Silver Spring and Greenbelt.
