Good afternoon, folks. Overall, my general thoughts on the winter storms ahead of us have not changed very much at all. I did tweak the call for snowfall for the first system coming in tonight and Wednesday…

Special 2

I nudged the numbers up a bit based on model data and an observation from today. What was that observation? It snowed in several areas of the state with bitterly cold, dry arctic air in place. That showed me the atmosphere wants to snow, and with deeper moisture coming in, that’s what it’s going to do.

With a frozen ground, you won’t lose a flake of snow to melting and roads may become snow covered for a while. Winter Weather Advisories are out for many with a Winter Storm Watch for the west…

Warnings

The winter storm coming Thursday night through Saturday morning is a headline maker from the Ohio Valley through the Mid-Atlantic and into the northeast. While the actual snow and ice totals for any one location aren’t yet known, I feel confident this storm will have a major impact on our weather in Kentucky.

The NAM is going to start getting attention since the storm is now with its range. Let me remind everyone of the inherent flaw of the model: It overdoes warm air advection. Many times, that cause the model to have too much precipitation and to be too far north. We saw this with both storms last winter. The model eventually corrects itself.

The NAM snowfall map through 7pm Friday illustrates my point…

NAM

That is very likely overdone and too far north. Even if the model were to be accurate, snow totals for the rest of the state would increase Friday night into early Saturday.

The GFS is starting to look more like the European Model. It’s been rather jumpy with it’s snow shield in recent runs, but it’s looking better with the placement…

GFSNotice how that is much farther south than the NAM. Every other model agrees with the placement, but the totals vary from model to model. High winds are also going to be a problem with this storm!

Again, I see no reason to make changes to my threat map…

Special 3

Updates come your way later today and on WKYT-TV starting at 4pm. Take care.
