New storms popping up
Sterling radar is showing some new thunderstorms developing to the north and west of the Baltimore area. They are drifting very slowly to the east, and forecasters say we can expect these or others to cross the urban corridor later this evening.
Here's the radar loop. And here is the view from orbit as of about 5:15 p.m. You can see the storms as the knobby spots on the otherwise smooth cloud cover.
Severe storm and flash flood warnings (orange on the map) were posted for parts of Frederick, Carroll, Baltimore and Harford counties and Pennsylvania counties just above the state line as a slow-moving storm churned along the Mason Dixon Line.
Chief threats include hail, strong downbursts of wind and heavy rain.
These storms are popping up in advance of what forecasters say is the main storm-maker, which is still in West Virginia. We could be seeing showers and thunderstorms well into the evening.
