Damp week expected despite Tropical Storm Alberto remaining at sea

May 21, 2012|By Scott Dance

Tropical Storm Alberto isn't expected to reach Maryland, but it should be a damp week nonetheless. In the Baltimore area, at least, it may not be damp enough to remedy developing drought conditions, though.

A low-pressure system is expected to stall over the mid-Atlantic today through Wednesday, according to the National Weather Service. Showers and thunderstorms could crop up along the Interstate 95 corridor today, but the chances for heaviest rain later in the week are southwest of us along the Shenandoah Valley, according to the weather service.

AccuWeather forecasters say showers will likely remain spotty and confined to the afternoon and evening hours, but also said some thunderstorms in the east could be "drenching."

Most of Maryland is still in need of a good drenching despite the fact that at least a trace of rain has fallen two out of every three days so far this month, as measured at BWI Marshall Airport. The airport has seen just over an inch of rain, while normall rainfall is 2.5 inches by this time in the month.

The rainfall deficit for the year has swelled to just shy of 6 inches at BWI.

On the bright side, heavy rains that fell on the lower Eastern Shore during some of those wet days have ended severe drought conditions there, as measured by the U.S. Drought Monitor. Most of the state along both shores of the Chesapeake Bay is under moderate drought conditions, with the rest except for Western Maryland abnormally dry.

Alberto is expected to remain well off the East Coast, moving to the northeast as it dissipates, according to the National Hurricane Center's outlook.
