Snow has been falling for several hours in what may turn out to be 2019’s first significant nor’easter. Upwards of half a foot of snow is now expected throughout the entire New York City Metropolitan Area. Winter Storm Warnings are in effect.
Over the past 24 hours, several computer models, such as the NAM3km and HDRPS (both detailed and accurate computer models) have zeroed in on this storm lasting from Sunday afternoon through Monday around 6 or 7 am ET. Both computer models have pointed to snow totals averaging about 5 to 9 inches in Manhattan, Long Island, New Jersey, the Lower Hudson Valley, and southern Connecticut.
While snow has been falling for some time now, roadways are only now beginning to become covered and particularly hazardous in some places. Other than up to several inches of snow on roadways by tomorrow morning, it is possible that because of warmer temperatures earlier Sunday, there may be small layers of ice beneath the snow. Although temperatures will warm to above freezing on Monday, rapid refreezing Monday afternoon may create black ice on roadways.
Over half a foot of snow is possible tomorrow across large swaths of the Mid Atlantic and southern New England. Starting around midnight tonight, snow associated with an incoming weak low pressure system will move into the NYC area. Most of the snow should move out of the area by noon, but not before dumping an estimated 4-8 inches of snow.
Expect roads to be slick and potentially covered by a layer of snow and potentially some ice during the morning commute.
Going into Tuesday and Wednesday of next week, a potentially major Nor’easter may bring up to 2 feet of snow to New England and the Mid Atlantic. However, as this storm system is still not yet developed, it is difficult to forecast this with great accuracy, but recent trends have indicated that the potential for a major storm is increasing, and in the meantime, we’ll keep you informed.
