A wave of low pressure riding along a slow-moving front will be the catalyst for today's rain, which will come via slow-moving showers and even thunderstorms.
The threat for severe thunderstorms with hail and damaging winds will be confined to the south of the front, from the D.C. and Baltimore area to the Deep South.
While a steadier, soaking rain is expected over the northern tier of Pennsylvania and upstate New York to the New York City metro area, thunderstorms with downpours will enhance the flash flooding risk farther south along the I-95 corridor west to southern Pennsylvania.
Highways as well as low-lying and poor drainage areas will be most susceptible to flooding. Never, ever drive through areas covered by standing or moving water.
Some rain will tend to persist into Saturday, especially across the lower mid-Atlantic, including in Washington and Baltimore.
Unfortunately for those with weekend plans, clouds will linger even longer into early Sunday.
