November 16, 2017 November precipitation has been normal plus or minus up to 1/2 inch or so in Maryland, the eastern panhandle of West Virginia, Delaware, and Virginia. November temperatures have been running about normal plus or minus a degree or two. Over the past 90 days, precipitation has been 2 to over 4 inches above normal in the middle and lower Delmarva Peninsula. Precipitation has been about normal or as much as 3 or 4 inches below elsewhere.

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

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

The weather outlook through the end of November calls for below normal precipitation. Temperatures are expected to be near or below average. The NWS Climate Prediction Center's 30 day outlook for December calls for near average precipitation and temperatures. The 90 day outlook for December 2017 through February 2018 calls for near or below average precipitation and above average temperatures.

The outlook for water resources and water supplies is fair for Delaware, Maryland, the eastern panhandle of West Virginia, and Virginia. With low sun intensity and the typical (seasonal) low water usage, only slow changes, if any, are expected in the near term. Slow degradation is possible in the event of a lengthy period of dry weather.
