RECORD SMASHING WARMTH WEDNESDAY – MUCH COLDER WITH AN ACCUMULATING SNOW POTENTIAL THURSDAY
A broad ride of high pressure at all levels of the atmosphere now in place will set the stage for a brief period of record smashing warmth on Wednesday with high temperatures ranging from the mid 60s to the mid 70s with the highest readings in valley locations. Low cloudiness and areas of fog that develop overnight will give way to a period of partial sunshine on Wednesday, in advance of an approaching cold front which will ultimately increase the clouds again gradually through the afternoon and bring a chance for scattered rain showers from the mid afternoon through the early evening. In advance of that front, a gusty southwest wind will develop which will help to boost temperatures by the early afternoon into the lower and possibly mid 70s for an hour or two, before temperatures slide back into the 50s during the evening and ultimately into the lower and mid 30s Wednesday night into Thursday morning.
ACCUMULATING SNOW POTENTIAL FOR THURSDAY
Colder air will flow into the region through Thursday morning with temperatures dropping back into the lower to mid 30s. A wave of low pressure passing along Wednesday’s cold front, which will be stalled south of the region by Thursday morning, will spread precipitation into the region during the morning potentially as a brief mix initially with a change to snow as deeper cold air becomes established. The zone of precipitation, however, could end up being somewhat narrow, so it’s quite the difficult call at this time pin pointing where the zone of accumulating snow will ultimately set up. But that detail should become more clear tomorrow. For now, it would appear that several inches of snow are possible for many areas from Thursday morning through the afternoon and early evening as the low passes by.
STORMY PATTERN FRIDAY THROUGH THE WEEKEND
Several additional low pressure systems will move through from Friday through Sunday bringing largely periods of rainfall to the region, although temperatures could be somewhat marginal in higher elevation locations so some snow cannot at this time be ruled out.
ICE JAM RIVER FLOODING POTENTIAL THROUGH THURSDAY MORNING
With rising temperatures through tomorrow, runoff from snowmelt will contribute to rising river levels, especially across the Adirondacks and central and northern Vermont where the mountain snowpack is deep. Flooding will be possible on some waterways, especially the northern ones, due to rising water levels as well as from the potential of ice jams. If you live on a river or stream that is prone to spring or ice jam related flooding, be on alert this week for that potential.
