Some familiar summer weather is expected across the D.C. area Saturday, as soupy air and oppressive heat fuel potentially severe afternoon and evening thunderstorms.
Thursday and Friday both saw afternoon temperatures climb well into the 90s, while high humidity pushed heat index values above 100 and provided energy for afternoon and evening storms.
Saturday will bring another hot and humid day, with highs in the upper 80s to low 90s and heat index values nearing 100.
Thunderstorms will start rolling into the D.C. region during the afternoon and evening, with the greatest severe weather threat along and north of Interstate 66 and Route 50. Damaging wind gusts will be the primary concern, 7News First Alert Meteorologist Steve Rudin said.
Storm coverage should decrease Sunday, but the heat and humidity will remain. Temperatures are expected to climb above 90 again, with heat index values 100.
Only isolated storms are expected Monday before rain and storm chances increase again Tuesday and into midweek, but heat will remain a concern.
In the District, Mayor Muriel Bowser activated a heat alert through 8 a.m. Thursday.
