Good Sunday evening, folks. We have a very interesting week of weather ahead of us. It’s a period that looks increasingly likely to throw a winter storm in our direction. Wednesday and Thursday have the potential to be very wintry around here.

I’ve been highlighting this threat for a while, and the models are now beginning to settle in on the potential. The European Model from earlier today gave a nice smackdown sleetstorm and snowstorm to much of our region. The NAM only goes out through Wednesday night, but is also going strongly in that direction…

Now THAT is one heck of a look! A very slow moving arctic boundary with waves of low pressure riding along it could produce a ton of precipitation.

The GFS goes back and forth with what it wants to do. It is probably the moodiest model I’ve ever seen. The late afternoon run is picking back up on the potential and shows this for the pure snowfall…

Again, the GFS is still trying to figure out the setup and that map does not include the sleet potential. As always, don’t take exact amounts and placement to heart from 3 days out.

The folks at the Weather Prediction Center are beginning to come to gripes with the potential for this system to develop. Here’s where they are showing the potential for 4″ or more of snow during the daylight hours Wednesday…

I’m not sure why the lines are so disconnected, but whatever.

Let’s what the overnight model runs bring.

Between now and then… watch for some icy roads later tonight and early Monday as temps drop into the 20s. Some areas of freezing drizzle and light snow will try to develop during this time.

Tuesday into Tuesday night will see temps spike briefly. That will bring the potential for heavy rain producing showers and some rumbles of thunder.

See you back here for a full update late tonight. Take care.
