Good evening, folks. I promised you guys another update and I’m here to deliver the goods, albeit with a short update. The overall setup continues to look active for the closing days of 2020 and I think this takes us into the start of 2021.

The main item of interest in the week ahead is the New Year’s Eve/Day storm system. One low works into the Great Lakes and pulls a cold front in here. Low pressure develops somewhere along this boundary and that could bring some wild weather with it.

Here’s what’s on the table of possibilities:

  • High winds
  • Heavy rain that can cause issues
  • Wintry mix and freezing rain
  • Accumulating snow

Again, how all that plays out remains to be seen, but this looks to be a disruptive storm system.

Here’s the late day GFS…

That’s a powerful looking storm system and the track of that will mean the difference between too much rain and a lot of winter weather… Or both.

This is a setup that’s likely to feature a lot of disruptive storms rolling across the country. Check out this active 500mb anomalies animation…

Enjoy the rest of the evening and I’ll see you back late tonight with a full update. Have a good one and take care.
