Synopsis:
A large upper level low pressure system in Canada will slowly retrograde westward over the next couple of days bumping into a high pressure system located over the central plains. This has created an extreme pressure gradient force which has caused a robust northern wind to develop. This northerly flow over the great lakes has activated the lake effect snow machine. This pattern will remain in place through Wednesday before high pressure retakes the state. This will cause for quite weather Wednesday evening and Thursday before a clipper system moves into the region causing more snow showers Friday and into Friday night.
Short Tem (Now through Wednesday morning):
The aforementioned low pressure system in Canada currently has a pressure of 967mb and it is bumping into a 1034mb high. You do the math people! That's an extreme pressure gradient and with great PGF comes great responsibility. Haha just kidding, but what it does mean is that a robust, sturdy, or whatever other synonym for strong northerly wind has developed which is just funneling cold air down from Canada and across the north east. This has also created lake effect snow bands that will persist until the PGF decreases and this storm system lifts off to sea.
Mid-term (Wednesday night through Thursday):
High pressure will slowly move back over the region on Wednesday causing decreasing clouds from the southwest to the northeastern portions of the state. Models show that skies should remain partly cloudy Through Thursday before a clipper system approaches the region. Look for very cold temperatures Wednesday and Thursday night.
Long-term (Friday):
The clipper system will swing through the state on Friday with up sloping regions picking up a few extra inches of snow before the system vacates the region on Saturday.
