Models Are Becoming Consistent On A Winter Storm For Sunday Into Early Monday; JRWeather Winter Storm Watch In Effect From 12AM Sunday Until 12AM Monday...
JRWeather WINTER STORM WATCH
JRWeather continues a Winter Storm Watch For All Of Vermont, And Clinton, Essex, Southeastern St. Lawrence, and Southern Franklin Counties In Northern New York From 12AM Sunday Until 12AM Monday.
A low pressure system that is expected to move through or very near the St. Lawrence Valley, will redevelop over Southern New England, then Track Northeast and into Maine by Monday. This will result in the potential of significant snow for the entire region.
At this time it appears snow will develop as early as Saturday night, and continue into early Monday morning. Current indications suggest the potential exists for 9 or more inches of snow by Monday Morning. In addition to the potential of snow, winds will increase into the 10-20MPH range with gusts to 35MPH possible.
If future model runs remain consistent then a Winter Storm Warning or Winter Weather Advisory may be issued later Today.
A Winter storm watch is issued when there is a strong potential for severe winter weather, but not yet imminent. In this case the Winter Storm Watch has been issued for the potential of significant amounts of snow. Stay tuned for further updates.
DISCUSSION
Warnings and Advisories for the upslope snow event have been cancelled as the moisture is diminishing. Next storm system look rather interesting at the least. A clipper system is expected to move towards the St. Lawrence river valley and then redevelop over or near Southern New England. The coastal system will then move northeast and up into Maine for Monday. The result may be for some heavy snow. The NAM model is now coming into agreement with the GFS. I just want to wait one or two more model runs before issuing any warning or advisories. I will say though the potential is very high for 9 or more inches of snow, especially from the Champlain Valley and into eastern Vermont. The western slopes could definitely pick up the highest amounts as winds turn to the northwest on the back of the system and enhance the snowfall significantly. Winds also look to be a concern as the pressure gradient tightens. Winds could gust up to 35MPH. That may be somewhat conservative. That's all I have for tonight. Make sure to stay tuned for further updates.
