Storms drop an inch of rain at BWI

Yesterday's thunderstorms delivered an inch of rain at BWI-Marshall Airport, the most in one day since July 31. We recorded 1.3 inches here on the WeatherDeck in Cockeysville, and just over an inch at The Sun building at Calvert and Centre streets downtown.

The CoCoRaHS network reported an astonishing 9 inches of rain yesterday in Ridgely, over in Caroline County on the Eastern Shore. Here are some other totals reported by the group:Flash flood watch area (green)

Denton, Caroline Co.:  3.31 inches

Sykesville, Howard Co.: 2.84 inches

Clarksburg, Montgomery Co.: 2.75 inches

Towson, Baltimore Co.:  1.8 inches

St. Michaels, Talbot Co.: 1.53 inches

Ellicott City, Howard Co.: 1.32 inches

Forecasters out at Sterling say there is more to come. With the ground saturated in places by Friday's rains, they have posted flash flood watches all across central and southern Maryland today and through the evening (green area on map). More showers and storms will cross the region ahead of an  approaching cold front with another 1 to 3 inches of rain possible.
