Towson, Baltimore took brunt of overnight rain

Sunday's rains got a late start, but when the skies finally opened up, they produced a gusher - especially in the Baltimore region, where morning traffic was a mess as a result of flooding on the JFX.

(It took me 65 minutes to drive from Timonium to downtown Baltimore, normally a 25-minute drive. Bailed off the Beltway at the top of the JFX, took Falls Road, which was jammed, too. Then Lake Avenue, to Roland, to University, to St. Paul. Got a commuting/weather nightmare story? Leave a comment and unburden yourself. Do you have storm video?

Reports to the CoCoRaHS network showed as much as 2 inches of rain fell in Baltimore, Towson and Ellicott City. There was more than an inch of rain overnight in Catonsville, Columbia, Jacksonville and Sykesville.

We recorded about 1.25 inches on the WeatherDeck in Cockeysville. The gauge here at The Sun, at North Calvert and Centre streets shows a storm total of 1.9 inches at 11 a.m. Monday. BWI reported just over an inch from the storms. Here is a sampling of rain totals for the 24 hours ending around 7 a.m. Monday.FLooding on the JFX

Towson:  2.18 inches

Ellicott City:  2.12 inches

Hamilton, (Baltimore City):  1.90 inches

Long Green:  1.84 inches

Frederick:  1.71 inches

Marriottsville:  1.65 inches

Catonsville:  1.57 inches

Columbia:  1.48 inches  

The thunderstorms caused 24,000 power outages among BGE customers, nearly all of which have since been restored. It also produced hail as big as an inch in diameter in many locations across Maryland, Virginia and West Virginia, including Frederick and Montgomery counties.

The thunderstorms and showers brought the rain totals for the month at BWI-Marshall Airport to about 2.18 inches. That's a third of an inch behind the "normal" pace for April through Sunday's date. April is, curiously, the driest month of the year at BWI, on average, with just 3.00 inches.

And if this month ends drier than that, it will be only the fourth month in the last 12 to end with below-average precipitation. It's been a very wet 12 months, with more than 17 inches of surplusNOAA precipitation.

We will likely get more rain through the day today as we continue under the influence of a large low-pressure system that is sitting pretty much on top of Maryland this morning, slowly making its way to the coast and out to sea. The barometer stands at a very low 29.33 inches at The Sun at 11:40 a.m. Monday, and is still falling.

We may get a few widely scattered thunderstorms in the late mix today and tonight. But it should all end by the morning rush hour Tuesday, if the forecasters are right. And then skies will begin to clear.

The forecast for the rest of the week looks pretty good, with sunny skies and temperatures climbing through the 60s and into the 70s by the weekend. Good roofing weather.
