Washington, D.C., faces not one, but two days of drenching, severe thunderstorms early this week.
After being spotty over the weekend, thunderstorms will ramp up for Monday and Tuesday. That is in terms of both coverage and severity.
The strongest thunderstorms will be capable of producing damaging winds and flooding downpours. A few communities may also see hail.
Commuters will likely experience a slower ride home than to work since Monday afternoon will prove to be more active than the morning.
On Tuesday, the extent of thunderstorms that unleash damaging winds will depend on the amount of sunshine that breaks through the clouds.
Regardless of whether clouds hold firm and limit the number of severe thunderstorms, there will be plenty of moisture in the atmosphere for torrential rain to pour down and potentially flood low-lying and poor drainage areas.
Extended disruptions to travel and outdoor activities can still be expected even in communities that escape damage and flooding.
Drenching thunderstorms push eastward Tuesday night, giving way to a drier and comfortable Wednesday and Thursday with low humidity and some sunshine.
While the core of the September-like air plunging into the Midwest will lose some of its punch before reaching the I-95 corridor, Thursday's high will only be held about five degrees below the typical mid-July high of 89 F.
