Much Needed Rain …. For Some

The past couple of days have been warm and very humid in the Baltimore area and several rounds of thunderstorms have developed in this tropical air. This is good news for an area that is suffering from a recent lack of significant rainfall. While some of the rain has been heavy, it hasn’t been evenly distributed around the region.

The graphic below is an image from the Sterling, Virginia, National Weather Service radar. It shows the estimated rainfall amounts measured by the radar for the weekend storms up until Sunday evening.

The green and yellow shadings show the areas that received the heaviest rainfall. A scale is provided at the bottom of the image. Notice that the 1″ to 3″ rains fell in a narrow arc from Frederick County north-northeastward into Pennsylvania and then turn southward into Harford and Cecil counties on down to parts of the Eastern Shore. A good portion of the Baltimore & Washington metropolitan area was left out of the significant rainfall.

On Sunday alone, BWI-Marshall Airport and the Maryland Science Center received less than a tenth of an inch of rain (up until 6:00pm) while the instruments at our studio on TV-Hill just a few miles away measured just over a half inch of rain. Hardly equal treatment.

Precipitation chances continue through Monday so maybe a few additional areas will get some of that much needed moisture.
