May 17, 2019: May rainfall has been 1 to 3 inches above average so far. Temperatures have been about normal plus or minus a degree or two. Over the past 90 days, precipitation has been about average or 3 inches above for most areas, though much of south-central and southeastern Pennsylvania are running 3 to 6 inches above.

Current (May 17) data from the U.S. Geological Survey shows that streamflows are above or much above normal. Groundwater levels are much above normal.

The weather outlook through the rest of May calls for near or below average rainfall along with above normal temperatures. The NWS Climate Prediction Center's 30 day outlook for June calls for near normal rainfall and near or above normal temperatures. The 90 day outlook for June through August calls for near or above average rainfall and above average temperatures.

The outlook for water resources and supplies is good for most areas but very good for southeastern Pennsylvania. Little change is expected in the next couple of weeks.
