High humidity is in the forecast for the rest of the work week, making it feel like the mid-90s Wednesday and Thursday. But when expected storms pass through Friday, things are forecast to cool off significantly for the weekend.
Highs around 90 are expected Wednesday and Thursday, but dew points of around 70 degrees could make it feel six or seven degrees hotter. Any dew point above 70 means a level of moisture in the air that is considered uncomfortable for everyone.
Severe storms are possible both Thursday and Friday. The National Weather Service's Storm Prediction Center is placing the odds of severe weather across Maryland and the mid-Atlantic at 15 percent both days, with a risk of damaging winds.
Thursday's forecast calls for typical summer afternoon storms, while Friday thunderstorms are likely throughout the day, according to the weather service's Sterling, Va., office.
Saturday and Sunday, highs are expected to barely break 80 degrees, though there is a chance for thunderstorms during the day Saturday.
Such relatively cool high temperatures have been rare this summer in Baltimore. Tuesday's high of 87 degrees at BWI Marshall Airport was the coolest this month, while only four days in July had highs below 85 degrees at BWI.
Overnight lows are forecast in the mid-60s for the weekend.
Sunday should be particularly pleasant, with temperatures mostly in the 70s and dew points of just 60 degrees.
