Rain over the last three days has brought the month's total to more than 4.6 inches at Baltimore-Washington International Thurgood Marshall Airport. That's more than 1.8 inches of surplus for the month through Monday, and brings the deficit since Jan. 1 down to less than an inch. 

Here are the monthly surpluses (+) and deficits (-):

Jan.: -2.00 inches

Feb.: +0.78 inch

March: -1.56 inches

April: +1.84 inches (through Monday)

The 4.6-inch total for April also makes this the wettest April since ... well, since last year, when we absorbed 5 inches of rain. Normal for a complete April at BWI is 3 inches, but we've topped 4 inches of rain in April only seven times since 1980.

Here are some rain measurements for yesterday from around the region.

Maryland streamflow is abundant for the time being. Here's the realtime flow map. And groundwater reserves continue to rise.

Here's the chart for that monitoring well out in Granite, Baltimore County, we like to track. Looks like their gear failed Sunday just as the latest rains began. But it's up about 4 inches since April 1.
