September 16, 2017 September rainfall has been about average plus or minus and inch or so in Maryland, Delaware, the eastern panhandle of West Virginia, and Virginia. Temperatures have been cool averaging 3 to 6 degrees below normal. Over the past 90 days, rainfall has been 5 to over 11 inches above normal in Delaware, much of Maryland, and northeastern Virginia. Rainfall has been 2 to 4 inches below in central and western Virginia and about normal elsewhere.

Current (September 16) streamflow data from the U.S. Geological Survey shows that streamflows are near normal. Groundwater levels are mostly near or above normal.

The state of Virginia has a "Drought Watch" in effect for north-central parts of the state.

The weather outlook for the rest of September calls for below or much below normal rainfall, though amounts could increase late in the period. Temperatures are expected to be above or much above average. The NWS Climate Prediction Center's 30 day outlook for September calls for above average rainfall and below average temperatures. The 90 day outlook for September through November calls for near average precipitation and above average temperatures.

The outlook for water resources and water supplies is good or very good for Delaware, Maryland, northern and eastern Virginia, and the eastern panhandle of West Virginia. The outlook is fair for central and west-central Virginia. Little change is expected in the near term. For now, a dry weather pattern has settled in, but it is offset by a weakening sun and lower water usage. This will, however, be watched for the longer term.
