12/5/16 Winter Threat Assessment Blog – Discussing a Cold and Active Pattern Next 2 Weeks of December

Synopsis: Firstly, I wanted to show a verification post of the system that occurred yesterday and what we had posted over a week ago for our target area…doesn’t get much better.

Latest look at our forecasted average temperatures over the next 2 weeks from the GEFS…we continue to see cold air intrude into the US through the heart of December. As good as it is that we have a good timespan of below normal temperatures across a good portion of the CONUS, we need to start seeing a better moisture supply to be give us those accumulating snow systems to push through the Plains eastward. There still is big variability from mid to late month as to whether the cold sticks around as well…we will update this in future blogs.

We see a favorable pattern over the next week for cold air filtering into the Lower 48, with big time ridging in the Bering Sea which has to force that colder, cross-polar flow into the CONUS bringing the coldest weather of the season.


Next Targeted system (~Dec 13-15th): Here’s the first look at this system from the BSR on the 14th of December (Graphic: Organicforecasting.com).


Here’s what the GFS has for a solution of this system via the 500mb pattern.


Here’s what the European has for a solution via the 500mb pattern…the two models are fairly close in time and impacts this far out.


Winter Threat Assessment:


Confidence and Risk:

  • We have above average to high confidence the pattern over the next 1-2 weeks turns cool to colder and active from west to east
  • We have below normal confidence the cold sticks around from the 15th beyond based off of latest data
  • Average to below average confidence in a wintry system moving through from December 13-15th
