Rain, drizzle and fog that have settled in during the past five days were expected to loosen their grip on the Baltimore area today.
Despite the gloomy conditions, this normally rainy month has seen only a paltry amount thus far, said Ken Shaver, a National Weather Service forecaster at Baltimore-Washington International Airport.
"We haven't even gotten an inch of rain yet," he said today, noting that the norm for the entire month of April is 3.35 inches.
The storm that brought heavier rain to the region last night and today -- and even heavier amounts in the mountains of Western Maryland -- carried the most significant rainfall in April. Forecasters have recorded some amount of rain at the airport on 12 of the 22 days in April.
But Mr. Shaver said that so far this year, 9.21 inches have been recorded there, about 3 inches below normal.
Another forecaster, Bill Miller, said a cold front was to pass through the metro area this morning, bringing a westerly flow of air initially, rather than the warm, moist easterly flow that has created the fog in recent days.
Behind the front, Mr. Miller said, conditions were expected to turn partly sunny later today and mostly sunny tomorrow, with temperatures between 75 and 80 degrees.
State police said last night's rainfall didn't produce any major flooding across the state but it did cause police to temporarily close 15 secondary roads in Frederick County.
Mr. Miller said flood watches that had been in effect overnight in Frederick and Allegany counties were lifted early today.
Meanwhile, last night's rain-slicked roads triggered a string of pile-ups on Interstate 695 near Towson and a mud slide-related accident near Hagerstown.
