More Snow On The Way?

Good evening, friends.  Conditions have been cold and cloudy on this Thursday, with highs limited to the mid 30's across the region.  As we get into our Friday, a disturbance will approach our area from the southwest, and create the potential for scattered rain showers.  Temperatures will fall through Friday night and Saturday, creating an environment that could possibly produce light, accumulating snow.

Tonight: Partly Cloudy, Low of 24, Calm Wind
Friday: Mostly Cloudy, Scattered Showers, High of 41, Calm Wind
Friday Night: Scattered Rain/Snow Showers, Low of 34, NW Wind 5mph
Saturday: Isolated Snow Showers, High of 34, NW Wind 8-12mph
Saturday Night: Partly Cloudy, Low of 21
Sunday: Sunny, High of 35
Sunday Night: Partly Cloudy, Low of 35
Monday: Isolated Showers, High of 44

Forecast Discussion

The surface model provided shows an area of high pressure currently residing over west central Kentucky.  This will keep calm, partly cloudy conditions in place overnight and to start our Friday, with scattered showers arriving tomorrow afternoon.

This system will continue to evolve to our southwest, then track northeastward, bringing moisture to our area as temperatures flirt with the freezing threshold of 32 degrees Friday night into Saturday morning.  I don't believe sufficient moisture will hang around long enough for any significant accumulation, with a good dusting to 1/2" possible north of the parkways in Grayson and Ohio County.  As you travel southeast from these locations, just like with the system on Wednesday, accumulations will become less and less likely.  The image above shows moisture exiting to our east, as the freeze line follows it across the state at 6am Saturday.  Temperature values will continue to fall throughout our Saturday, with readings forecast to stall out in the lower 20s early Sunday morning.

Sunshine will return to our entire region on Sunday, as high pressure builds in from our west.  Although rays of sun will be back, temperatures will once again be limited to the mid 30s.  Another weak disturbance is slated for early next week, with the opportunity for snow on the horizon, once again.  As for now, this does not look to be a significant event.

That will be all for now, folks.  I'll be back tomorrow morning with a fresh update on our snow chances for Friday night into Saturday.  Enjoy your evening, and thanks for relying on ~ Beech Tree Weather!
