Rain subsides, creeks rise, more due

 NWS

The showers and storms that brought 1 to 3 inches of rain to parts of Central Maryland and Virginia are moving off to our northeast this morning. That's eased back on the rain rates. But, after a brief respite late tomorrow, forecasters say we can expect another round of significant rainfall Sunday and Monday as yet another storm system takes aim on our region. Don't look for any sunshine until Tuesday.

Rain totals reached 1.3 inches here at Calvert & Centre streets by late morning Friday. The instruments at BWI Marshall airport have recorded almost 2 inches since the rains began late yesterday, erasing the precipitation deficit we've run since Jan. 1, and adding about an inch of surplus.

Down on the Lower Eastern Shore, where moderate drought conditions have persisted even as the northern and central counties shook off the water shortages that began last May, heavy rains overnight have surely eased their plight some.

Salisbury Airport is reporting 1.16 inches of rain so far. Accomack Airport, down on Virginia's Eastern Shore, received 0.84 inch. Here are some other morning rain totals from unofficial weather service data:

Washington DC: 1.65 inches

Millersville, AA Co.: 2.28 inches

Edgemere, Baltco.: 2.39 inches

Indian Head, Chas. Co.:  2.43 inches

Baltimore City:  1.43 inches

Bel Air, Harf. Co.:  1.15 inches

Columbia, How. Co.:  1.15 inches

Potomac, Mont. Co.: 1.36 inches

Fort Washington, PG Co.: 3.76 inches

Here are more readings from CoCoRaHS.

The heavy rains have flooded many roads in the region, especially in Virginia and Southern Maryland. Many streams along the I-95 corridor are running at record highs for this date. Here's more on streamflow.

High winds in thunderstorms caused some structural damage in Arnold, Anne Arundel County, near Maryland City in Arundel, and dropped trees onto the southbound lanes of the BW Parkway at Rte. 198.

And there's more to come. Chances for showers will persist into tomorrow, then ease Saturday night. We may even see some stars. But then the next storm system arrives from the west Sunday afternoon, continuing into Monday. 

Here's the radar loop, showing the rains headed away to the northeast. For now.

I am wondering just how intense this storm was last night (Thursday night) in Anne Arundel County, specifically Odenton. My dog and I were awakened at some odd hour in the morning by the loudest, groundshaking noise I have ever heard. Sort of a windy boom. The house shook and some furniture was a little out of place on the first level this (Friday) morning. Is there a chance a tornado touched down? Earthquake? Or a chance of one of those sink holes in Odenton, MD?

FR: No tornado here, no quakes. But there were some pretty rough storms around, with some noted damage in Arundel. Here's our Web story: http://www.baltimoresun.com/news/weather/bal-weather0509,0,2653667.story
