Good Monday, everyone. As snow showers and squalls wind down, it’s time to focus more on the increasing potential for a weekend storm system to impact our region. This kicks off the much talked about second week of January and a significant round of winter weather arriving.

Once a late week system moves away, cold air dives into the region on Saturday. This happens as another low pressure develops near the Gulf and rides northeastward. The European Model has been fairly consistent in showing this and now the GFS has finally caught on…

That would bring a healthy swath of snow across much of the region.

The Canadian Model went from basically having no storm to one that’s pretty wrapped up and likely too far west. Look at the snow map from that model run…

Again, don’t take the placement of that to heart. It’s just an indication of the type of system showing up on the models.

As the models get a handle on the amount of arctic air coming into the country, I suspect we see that system wind up as an “apps runner”.

And the air coming in behind that storm is cold. GFS lows for early next week…

The arctic wave that follows that is also starting to show up on the GFS…

There’s a lot of winter on the way to much of the country in one of the great all-time pattern flips!

BTW.. you guys got a midday update from me. That should tell you something. 😉

See you later this evening. Take care.
