Dry out today; more rain coming

 NOAA

We'll get one more day to dry out from the weekend storms, forecasters say. Then, a new cold front and associated low-pressure system will bring new rains. You can see the system in the blue and red areas of this satellite image. The precip may pose issues for areas still coping with high water. But for the most part rainfall amounts will not be anything close to what we saw last weekend.

This morning's discussion from Sterling says clouds will thicken this afternoon, and the first chances for renewed shower activity will come late in the day and evening on Thursday. They're calling it scattered and isolated at first, becoming more widespread overnight into Friday before ending after noon. They're talking about a half-inch of new rain at the most. But for some, that's more than enough.

"Flooding concerns would remain ... for the trouble areas of the past few days across north central Maryland and extreme northern Virginia," the folks at Sterling said.  "Needing only around a half-inch of rain to raise area rivers to action stages." On the other hand, they added, "with area rivers beginning to drop out of flood stages and another day to recover ... the incoming rainfall may not be enough to raise concerns, but in a few isolated areas."

Coastal flooding remains a concern, too, as heavy runoff and southerly winds keep lots of water in the bay. Coastal flood advisories are posted through Thursday morning. Watch out for unusually high tides along the bay. There's a coastal flood warning up for Dorchester County, on the Eastern Shore.

Beyond the new rain, we should expect winds to pick up on Saturday morning as the passing low gets wound a little tighter. The weekend looks partly to mostly sunny, with daytime highs near 70 degrees, as the storms move away.
