Good Thursday everyone and Happy Thanksgiving! The weather for this special day is looking as good as we can get this time of year… especially in the pattern we are in. I have a lot to get to and a short time to do it in so let’s get at it.

This Thanksgiving will feature temps in the 50s under mainly sunny skies.

A weak cold front will slip across the state Friday and will bring in some cooler air. A few clouds will be on the increase during the day as winds kick up. Temps will be back in the 40s for highs.

That brings us to the weekend and what appears to be a significant winter storm across the eastern half of the country that is likely to impact the state Sunday into Monday. Before I get into that I want to throw out a quick word about Saturday. Several of the models have been trying their best to bring a touch or rain or snow toward us. The GFS is the most aggressive with this possibility and it is something to watch for. As if I need something else to have to deal with!

The Sunday storm is going to be a complicated one as we will be dealing with a clipper heading into the Ohio Valley that should spawn another big low to our south and east. Exactly when and where this low forms is up for debate and will mean the world to us in terms of what and how much we get. Let’s get to some maps for ya. We start with the European model which has been fairly consistent in recent days…

SUNDAY


You see the potent clipper moving in and transferring energy to a new low forming in the Carolinas. That would be a early day wintry mix that changes quickly to snow as the low in the east strengthens and heads north…

MONDAY


As you can see… that turns into one heck of a storm and would mean widespread and wind whipped snows around here Sunday night through Monday night.

The GFS model has been coming around in recent runs toward showing something similar… if not more powerful. The runs from early in the day Wednesday were showing this low coming much farther west bringing a major snowstorm to the Ohio Valley. The latest run from late Wednesday evening was farther east with the low…

Sunday Evening


Monday Morning


I think this run is too far to the east… but the GFS is getting the overall idea down and that is we should have a nice sized storm moving through the eastern US. IF this solution of the GFS were to turn out to be correct… it would throw a lot of atlantic moisture back into a closed low moving across Kentucky…

GFS Upper Level Chart Monday Morning


The Euro and GFS solutions shown in this blog post would both bring a widespread snowfall to our region. Just how much is up for grabs as we have a lot of variables that have to be worked out. But… if you are curious as to some snowfall charts…


0Z GFS Through Monday Evening


The dark green is up to 6″ of snow. That map basically blankets the state with a 2″-6 snowfall with a little more on top of that Monday night.

The GFS run from a few hours earlier brought the low MUCH farther west and had a HUGE snowstorm for western and northern Kentucky…

18z GFS Through Monday Morning


You get the picture as to what I am talking about here so PLEASE DO NOT take any one model run or model as the gospel as things will continue to evolve over the next few days. We have a few days to watch this thing so make sure you check back for the latest as I will be updating several times a day through the weekend.

If I continue to see the models in the same ballpark… we will shift into THREAT MODE for the first time this season for a possible significant early season winter storm.

Again… keep checking back for updates and have a Happy Thanksgiving! Take care.
