Sunday Afternoon Update

Good afternoon, everyone. It’s another busy day for your friendly weatherdude, so this is a quick update with the chance I don’t get around to another one this evening. It’s all eyes on a very harsh period of winter weather for the week ahead. Arctic temps and snow chances take center stage.

The first system is out arctic front slamming in here Monday night. That boundary will have temps spiking ahead of it and tanking behind it with a band of snow taking over. As expected, this will primarily impact central and eastern Kentucky…

Right now, the best chance area looks like a few inch snowfall, with higher amounts near the Virginia border counties. Exactly where that swath begins in central Kentucky is still in question. Winds will be cranking and create some blowing snow for areas getting in on the action.

I like what the Canadian is doing in terms of coverage, but it’s too skimpy in the far southeast…

The NAM and GFS are a little more narrow with the snow band, but heftier in the southeast, which I like…

NAM

GFS

School delays and cancellations will likely come from that across the eastern half of the state.

As that system moves away, arctic snows break out from west to east across the entire state Tuesday night and early Wednesday. This is a low QPF scenario as it’s showing up in arctic air, so the atmosphere maximizes the snow potential. Notice how the numbers on the Canadian jump up when we add Tuesday and Wednesday together…

If you’re into the whole frozen tundra thing, Wednesday and Thursday are right up your alley. Bitterly cold temps and gusty winds will combine to send wind chills toward dangerously cold levels…

That’s some cold stuff, folks, but we are getting to the time of year I really start craving spring. Unfortunately, our winters no longer show up until late in the season and cut into our true spring. The past decade of weather has proven this to be the case more times than not. You know what I have to say about that? Blah, Blah, Blah!! 🙂

I’ll try to update again late this evening, but the long and winding road has my name on it. Enjoy the rest of your day and take care.

Arctic Cold and Snow Chances Ahead

Good Sunday, everyone. The week ahead continues to feature a very harsh look as bitterly cold air takes control of the pattern. This air will be introduced by a snow maker rolling in here Monday night and Tuesday, and should feature additional snow chances later in the week.

Let’s begin with a period of light snow and light rain rolling across the state early today. This system moves through quickly, leaving us with better weather this afternoon and evening…

Our Arctic front is going to slam in here Monday night and will feature a wave of low pressure along it. As we have talked about, most of the precipitation falls behind the front, giving us our region the increasing potential to put snow on the ground. That’s especially true for central and eastern parts of the state.

The NAM shows what I’m talking about…

As expected, the GFS continues to shift west with the whole setup and is also picking up on the light snow maker zipping in behind it on Wednesday…

The above map is only for the arctic front snow potential and doesn’t include the Wednesday system. That second system is a likely arctic snow maker for most of the region.

The Hi Res NAM only goes through Monday night, but shows the beginning of a similar look to the above maps…

In the bizzaro land of model mania, the European Model is the lone dog in now showing more of a progressive system. It looks a little suspect with all that action down along the Gulf…

For areas getting snow, blowing snow will be an issue as winds will absolutely crank during this time! Travel conditions Monday night and Tuesday could go downhill very quickly across central and eastern Kentucky.

Bitterly cold temps slam in behind this system on Tuesday, with the coldest arriving for Wednesday and Thursday. Air temps may drop to zero or below in some parts of the state. Wind chills from Tuesday night through early Friday will be in the danger category. Wind chills by Wednesday morning are already as low as -20 on the NAM…

As the Polar Vortex relaxes later in the week into the weekend, watch for another potential snow maker to work in from the west.

I will have updates later today and maybe a First Call Map for Monday night and Tuesday. Have a good one and take care.
