Higher Summits Forecast

Low pressure will continue to move up the St Lawrence River Valley today spinning in moisture first from a warm front this morning followed by a cold front this afternoon. The models are suggesting that the low may bring a slight chance for thunderstorms this morning which seems realistic given the current energy present on radar, the recent nearby soundings and regional lightning detection showing a few strikes to our south and west. Some thunderstorm cells may bring heavier periods of rain, small hail, or gusty winds. But overall, this will just be a quick moving rain storm than anything else. Although rain is expected for the better part of the day, as the cold front passes, temperatures will drop below freezing allowing some freezing rain, sleet and snow showers to mix in. Occasional showers will continue overnight into early Saturday as ample moisture is met with ideal upslope flow conditions. Any snow that falls will be little to no accumulations. As the low exits overnight into Saturday, high pressure will build back in along with drier air late in the day tomorrow allowing for some afternoon clearing. Temperatures will be falling today into the overnight hours with the frontal passage then remain fairly steady tomorrow as a cooler northwesterly flow continues and becomes fairly isothermal. And winds will be on the increase into the overnight hours before gradually decreasing tomorrow as the low exits and the high begins to crest in allowing the gradient to weaken.
