Mid-May - Rain Boots Required

may 1-15 pdpt map

May 1-15 precipitation was above normal for a majority of the Northeast, with many areas seeing more than 150% of normal.

Almost the entire Northeast has seen above-normal precipitation during the first two weeks of May, generally ranging from near normal to more than 200% of normal. All 35 major climate sites were wetter than normal, with 26 sites ranking this first half of May among their top 20 wettest. In fact, Providence, RI, and Newark, NJ, have seen so much precipitation during the first two weeks of May that the entire month already ranks among their top 20 wettest Mays on record. The above-normal precipitation helped the Northeast become free of drought for the first time since mid-April 2016.

May is not a particularly snowy month and despite the cool and wet conditions, this one has been no exception. A few higher elevation locations in West Virginia, New York, and northern New England have seen less than 2 inches of snowfall; otherwise, much of the region has seen none.
