In fact, Buffalo and Rochester, NY, received an entire May’s worth of rain in just the first week of the month! However, a portion of central/western West Virginia did see drier-than-normal conditions.

The above-normal precipitation helped end drought conditions across the Northeast, with the region becoming drought-free (in early May 2017) for the first time since April 2016.

Overall, spring average temperatures ranged from 2°F below normal in northern New England to 3°F above normal in West Virginia and western Pennsylvania. Twenty-five of the major climate sites experienced a warmer-than-normal spring, with 12 of them ranking this spring among their top 20 warmest on record.
At the major climate sites, spring average temperatures ranged from 1.3°F below normal in Worcester, MA, to 3.1°F above normal in Elkins, WV.

March was snowier than normal for much of the region, mainly due to a mid-month Nor’easter. April snowfall was generally near to below normal, except in portions of northern New England. In May, no sites received measurable snowfall. With that, spring snowfall ranged from 12 inches below normal in parts of northern New York and central West Virginia to more than 24 inches above normal in central New York. Twenty-nine of the 35 major climate sites were snowier than normal, with 19 of them ranking this spring among their top 20 snowiest. Conversely, two ranked this spring among their top 20 least snowy.
Spring snowfall at the airport climate sites ranged from 7.2 inches below normal in Charleston, WV, to 22.2 inches above normal in Binghamton, NY.
Seasonal snowfall varied, but was generally near to below normal in the Mid-Atlantic and near to above normal in New England.
The snow season, which runs from October through May, was variable, ranging from more than 36 inches below normal to more than 36 inches above normal.

Just last year the site had its least snowy season on record. On the other hand, seven sites ranked this season among their top 20 least snowy on record.
At the major climate sites, seasonal snowfall ranged from 38.9 inches below normal in Elkins, WV, to 51.8 inches above normal in Binghamton, NY, which was their snowiest season on record.
How is summer shaping up? Well, NOAA’s Climate Prediction Center (CPC) indicates there’s an increased chance of above-normal temperatures for the Northeast during summer, but the precipitation outlook calls for equal chances of below-, near-, or above-normal precipitation.
CPC’s summer temperature outlook indicates increased chances of above-normal temperatures.
