The Dry Island Has Shrunk...A Lot

We hadn't updated things with the dry island for a few weeks given the plethora of rainfall that some of us have received, which had kicked a pretty extensive dent into what was shaping up as a pretty sharp dry spell earlier this Spring. Thankfully, the region's dry island looks much smaller compared to three weeks ago at this time.  Although some of the rainfall has been excessive, the region is still running at a yearly rainfall deficit of anywhere from one to six inches depending on location, with the lowest rainfall deficits to our north over the Lehigh Valley and Poconos.

The only sections of the Northeast that are classified as being dry are Southern New England (generally Connecticut and Western Massachusetts), Western New York State, and the southern half of the Delaware Valley.

That does include a small sliver of Pennsylvania, believe it or not.  According to NOAA's Drought Monitor, a tiny sliver of Chester and Delaware Counties are classified as being abnormally dry.  Compared to where we were a few weeks ago, this is much improved overall as the driest parts of the region are still South Jersey and Delaware (areas that have missed out on receiving the heaviest rainfall over the past few weeks).
As the cutoff for the Drought Monitor is Tuesday morning, there probably won't be much change in the standing on this between this past week and the upcoming report on Thursday.  However, the prospective rainfall on Tuesday night (especially if it can organize and cross portions of Delaware and South Jersey that could use some rain) may go to eliminate the rest of the dry island from the Delaware Valley altogether.
