Here We Snow Again!
The chance for snow on Wednesday evening is looking more and more likely. Here is the basic set-up:
A series of waves of low pressure have been moving through bringing us rain, however the one on this surface map will be the last to go through, and the strongest.
The low pressure system will get upper level support from the west allowing it to quickly strengthen. This will bring in colder air and and bring it in faster.
The low pressure center will then move over to the coast and continue up the seaboard creating what could be our first December Nor'easter.
We will see heavy rains from this on Wednesday before the cold air moves in. As the cold air filters into our area, rain changes to snow starting in the northwest by the mid afternoon. The Valley should see the change to snow throughout the evening.
Totals will be very dependent on just how cold the air gets, and how quickly.
The latest forecast brings more to the west because the snow will start earlier.
Most of the snow should stay off the roads until late Wednesday night because the roads will stay above freezing most of the time.
We should still be ready for slick conditions late Wednesday night and Thursday morning. Many sidewalks and roads will be wet, even if not covered in snow and likely will freeze.
Lastly, find your snow brushes and ice scrapers before you go to bed Wednesday night because you'll probably start with some a frozen mix on your car for your commute Thursday morning.
