February 21, 2019: February precipitation has been about average or up to an inch or so above. Temperatures have been 2 to 6 degrees above normal. Over the past 90 days, precipitation has been 4 to 7 inches above average in most areas but 1 to 3 inches above in southeastern Virginia.

About 1 to 4 inches of snow is on the ground in most areas except for the Delmarva Peninsula and southeastern Virginia. In the eastern panhandle of West Virginia and far western Maryland, 4 to 7 inches are on the ground. The water equivalent of this snow (or the water in the snowpack that will be released when the snow melts) is 1/2 to 1 1/2 inches in the eastern panhandle of West Virginia and far western Maryland. Elsewhere, under 1/2 inch is on the ground where snow is on the ground. Most of this snow is not hydrologically significant and is expected to melt fairly quickly. Where snow is deepest, a rapid melt could add up to a couple of feet rise to streams and rivers.

Current (February 21) streamflow data from the U.S. Geological Survey shows that streamflows are above or much above normal while groundwater levels are above or much above normal.

The weather outlook through the week or so of March calls for above average precipitation. Temperatures are expected to start warm but trend back to below normal for much of the outlook period. The NWS Climate Prediction Center's 30 day outlook for March as well as the 90 day outlook for March through May calls for above average precipitation and above average temperatures.

The outlook for water resources and water supplies is very good or even excessive at times with little change expected in the next couple of weeks.
