A clear sky this evening with diminishing wind will allow the temperatures to drop into the mid single digits early in the night...As the night goes on clouds will be on the increase keeping the temperatures above zero ( but just barely) overnight.
Sunday we will see the clouds thickening ahead of the next storm system...Highs on Sunday will be in the low to mid 20s.
Snow will develop Sunday night and may be heavy at time after midnight into midday Monday.The heaviest snow appears to be from the Mohawk valley south with lighter amounts across the Adirondacks... Once again there will be a fairly sharp cut-off from north to south.
A WINTER STORM WARNING is in effect beginning SUNDAY AT 9 PM continuing into Monday evening for the region with the exception of the Adirondacks where a WINTER STORM WATCH is in effect. Although the storm will not begin for another 24-36 hrs is areas likely that 7" or more of light, powdery snow will fall in the warning area. Accumulations look to be generally 6-12" through the capital District, Mohawk valley and the Hudson Valley south of Albany and Berkshire county...Lesser amounts across the Adirondacks... A more specific snowfall forecast will be issued on Sunday as the storm tracks become more clear.
Travel conditions will deteriorate rapidly late Sunday night and Monday morning. Significant snowfall rates Monday morning into the afternoon are expected. In addition, the very cold air will reduce the effectiveness of salt. Have contingency plans ready for school delays and/or closings for Monday. Although the track of the storm is not certain as of this update ( Saturday evening) it does appear there will be enough snow to cause a disruption in travel.
After the storm moves out Tuesday frigid air will return...I do not expect any temperatures above freezing for at least another week.
