Well this is a change. CPC actually has colder then normal temps for all of February! Feels like forever since I made a thread with below normal forecasted temps.
Looks like after this snowstorm we get a little cutter and some cold arctic air behind it which should set the stage for a long duration LES event. A nice -EPO setting up allows some really cold air to make it into our area.
Thursday night into Friday, an area of low pressure will track
northeast across the Central Great Lakes, occluding in the process.
Precipitation will overspread the region as the area of low pressure
tracks across the Great Lakes. First the warm front associated with
the system will track northeast across the area through Friday
morning, followed by the cold front for the late morning into the
afternoon.
Temperatures on Friday will be a bit warmer in the lower elevations,
resulting in rain or a mix of rain and snow. The higher elevations
should stay mostly snow for the day on Friday. As the cold front
passing over the area, and cold air advection brings temps down, any
remaining rain will change over to snow.
Behind the passing cold front, 850H temps in the -10C to -15C range
will help support the potential for a lake response off of both
lakes. Potential lake enhanced and then lake effect would continue
through most of Saturday.
A wave of low pressure and trailing cold front will track across the
area on Sunday, bringing a return to cold temperatures once again.
Lake effect behind this passing system also looks possible with 850H
temps dropping to -15C Sunday night, and cooling even more so from
there.
