January 16, 2018 So far in January, precipitation has been about average plus or minus about 1/2 inch. January temperatures have been very cold averaging 6 to almost 9 degrees below normal. Over the past 90 days, precipitation has been about 2 to over 5 inches below average.

Snow cover for mid-January is minimal with only an inch or two on the ground in far western Maryland. But, a snowfall early in the outlook period is expected to increase these numbers. For now, the snow is not hydrologically significant.

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

The US Drought Monitor for January 11 shows that central Maryland and northern, central, and southern Virginia are in Moderate Drought. "Moderate Drought" means that some damage to crops and pastures can be expected; streams, reservoirs, or wells will be running low; some water shortages are developing or are imminent; and voluntary water-use restrictions are requested.

The state of Virginia has a "Drought Watch" in effect for northern, central, and southern parts of the state.

The weather outlook for the next couple of weeks calls for near or above average precipitation. Temperatures are expected to start the period below average but then moderate quickly to above normal. The NWS Climate Prediction Center's 30 day outlook for January calls for near average precipitation and below average temperatures. The 90 day outlook for January 2018 through March 2018 calls for near 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. In the near term, only slow changes, if any, are expected. Slow degradation remains possible should dry weather continue.
