October has been warm averaging 5 to over 8 degrees above normal. Over the past 90 days, rainfall has been 4 to 10 inches above normal in parts of the Delmarva Peninsula and Chesapeake Bay area. Rainfall has been 2 to over 4 inches below in central and western Virginia and about normal elsewhere.

Current (October 21) streamflow data from the U.S. Geological Survey shows that streamflows are 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 into early November calls for above normal precipitation with drier conditions expected in early November. Temperatures are expected to be near or below average. The NWS Climate Prediction Center's 30 day outlook for November calls for near average precipitation and temperatures. The 90 day outlook for November 2017 through January 2018 calls for near average precipitation and above average temperatures.

The outlook for water resources and water supplies has been downgraded a bit and is now fair for Delaware, Maryland, and the eastern panhandle of West Virginia. The outlook remains fair for Virginia. An extended period of dry weather has settled in. With occasional wet weather along with the sun decreasing in intensity, only slow changes have recently occurred. As we head deeper into autumn, slow degradation will occur if dry weather persists. But, fairly quick improvement can occur if an extended wet period occurs.
