There were also reports of significant freezing rain glazing in the region. Our new seasonal total snowfall is 19.5″
17 Feb 2018 2.9 ajb=M ds=3.2 jpk=3.0 rgg=2.5 rjs=M wfs=2.8 22.4
A surface trough off the southeast coast in response to an eastward moving upper level trough developed into a storm offshore of VA during Saturday. As the storm moved rapidly ENE it deepened and produced bands of heavy snow over parts of eastern PA and NJ for a short period during the evening of Feb 17, producing 2.9″ of new (wet)snow in the GFDL area (lack of low-level cold air kept temperatures >= freezing during most of the event). There were reports of as much as 9″-10″ in some parts of Hunterdon and Morris counties. Our new seasonal total snowfall is 22.4″
2 Mar 2018 1.4 GFDL=1.4 23.8
In response to a deepening upper-level trough, a moderately strong storm in the mid-west on Thursday, March 1, deepened as it moved eastward and re-developed off the NJ coast in the very early morning hours Friday. It rapidly intensified so that it was powerful Nor’Easter by Friday morning located just south of eastern Long Island with a central pressure of 983mb. The storm produced heavy rains overnight throughout the eastern PA / NJ region and continued to deepen throughout Friday. During Friday the heavy rain mixed with and changed to heavy snow in many parts of the area including the Princeton area, with 1.4″ being measured at GFDL. Very heavy snow occurred in the Poconos across northern Sussex county NJ and into the Catskills where many locations received a foot or more and some places approached two feet. (A maximum in snowfall of 40″was reported from Cobleskill,NY!). In addition to snow, the tight pressure gradient produced very strong winds, with many NJ locations experiencing gusts of more than 60mph and some over 70mph. SE New England was particularly hard hit by this storm,with historic flooding at high tides and gusts reported over 90mph.

A mid-west storm that brought blizzard conditions in parts of the Dakotas and heavy snow across Minnesota moved eastward and transferred energy to the East Coast resulting in a re-development of a storm near the Virginia Beach area very early Wednesday, Mar 7. After initially bring light mixed precipitation to the Princeton region overnight Wednesday, the storm intensified and produced convective bands of very heavy snow mostly during the afternoon with snowfall rates of 2″ to 3″ per hour in places, including the greater GFDL/Princeton area. There were numerous reports of “thunder snow” throughout the area. Because it was convective, there were some large variations in snow fall amounts ranging as high as 26.8″ in Montville (Morris county) while less than 15 mi southeast, Central Park in NYC reported only about 3.2″.(More snowfall reports in the PA and NJ area can be found at: https://forecast.weather.gov/product.php?site=NWS&issuedby=PHI&product=PNS&format=CI&version=1&glossary=0.)

The fourth Nor’Easter of March 2018 has ushered in Spring by being the largest snowstorm of this 2017-18 snow season, producing an average of 11.0″ over the GFDL snow observing region. The storm was located around Colorado late Sunday, March 18 and associated with a weak upper level short wave, moved eastward to North Carolina by Tuesday morning. It then moved east northeastward producing generally light mixed precipitation in our area on Tuesday. During Tuesday another upper level short wave well to the west of this surface low was deepening and initiated the development of a secondary storm center over South Carolina late Tuesday which intensified a bit and eventually became the main Nor’Easter storm as it moved slowly north eastward to a position off DelMarVa by Wednesday evening. One of the highest snow totals in NJ was reported by a GFDL snowpool observer at 16.4″ with amounts approaching 20″ being reported in some parts of eastern Long Island. The snowpool total is 45.1″.
