December 14, 2018 December precipitation has been 0.5 to 1 inch below average for most areas so far. Areas in central and southern Virginia have been closer to average. Temperatures have been 1 to nearly 5 degrees below normal. Over the past 90 days, precipitation has been 3 to 10 inches above average for most areas.

Snow depths range from 2 to 6 inches in central and southern Virginia as a result of a recent snowstorm. Elsewhere, little or none is on the ground. The water equivalent of this snow (or the water in the snowpack that will be released when the snow melts) is 0.5 to over 1 inch but is expected to melt fairly quickly.

Current (December 14) streamflow data from the U.S. Geological Survey shows that streamflows are near or above normal while groundwater levels are much above normal.

The weather outlook into late December calls for above average precipitation to start the period but then near or below average precipitation afterwards. The NWS Climate Prediction Center's 30 day outlook for December calls for near or above average precipitation and above normal temperatures. The 90 day outlook for December 2018 through February 2019 calls for near or above average precipitation and near average temperatures.

The outlook for water resources and water supplies remains very good or excessive with little change expected in the next week or two.
