Light Snow Expected Overnight

With light snow expected overnight that could bring impacts tomorrow, we have been updating Premium subscribers with potential school and travel impacts.  Below we outline the forecast for the region:

Overnight we should see increasing clouds through the night.  Low temperatures get down to the low/mid 30s at the coast and maybe hit 30 further inland.  Temperatures gradually begin to warm overnight with a weak southerly flow.  Light snow showers break out between 1 and 4 AM across the region from west to east.  Between 4 and 8 AM precipiaion could briefly become moderate, cooling surface temperatures a bit.  Between 4 and 6 AM snow turns over to rain at the coast, with that same transition happening inland bewteen 4 and 7 AM.  Rain showers then continue through around 10 AM and we dry out from there.    Some models even show rain dominating the entire time at the coast, but at this point I favor some snow down to the coast thanks to a cold column it will just struggle to stick with relatively warm surface temperatures.

Accumulations are expected to be very minimal.  Most coastal areas likely see snow struggle to stick on roadways and other surfaces, especially across western Fairfield and all of Westchester counties where warmer weather is expected.  Still, coastal accumulations of up to around a half inch, primarily on grassy surfaces, are possible.  Further inland, accumulations of up to an inch are possible, mainly in elevated regions. North of I-84 isolated amounts a bit higher than an inch are possible as well, though widespread amounts of over an inch look unlikely thanks to relatively marginal surface temperatures.  Most accumulations are likely to occur between 4 and 7/8 AM before surface temperatures warm significantly.

At this time, travel looks to be potentially slippery in coastal areas between 3 and 6 AM and inland areas between 3 and 7/8 AM Minor impacts are possible, as snow may be able to stick on roads further inland with surface temperatures just slightly above freezing.  Any more intense bursts of snow would quickly stick and cover roads with margial inland surface temperatures.  At the coast, south of the Merritt, we will still struggle to see temperatures consistently below average that would allow any real sticking of snow on the roads.  Though patchy slick spots could exist, no widespread impacts are expected even if there are some accumulations on grassy surfaces.
