Monday Evening Update

Good evening, everyone. Another big temperature swing will lead to more winter weather rolling in here on Wednesday. This is a setup that can throw down accumulating snow into much of the region, with additional snow makers lurking this weekend into next week.

Let’s focus this update on the Wednesday-Thursday setup. It’s a cold front working through here as a wave of low pressure develops along the boundary. Rain along and ahead of the front changes to a mix and snow behind it as temps crash.

Where that marriage of the cold and deeper moisture happens is still in dispute with slight differences showing up on the models.

The NAM likes that hookup in the west then rolling east. You can also see the arctic front with some more showing up behind that by Thursday night…

Here’s the NAM snow map through Thursday morning…

You can see the better snows across the east because they get the moisture from the wave of low pressure. The GFS isn’t quite as snowy as the NAM, but also has better stuff in the east…

The European Model has a similar theme across central and eastern Kentucky…

The new version of the GFS continues to be on steroids with the precipitation amounts with this setup…

Again, that model has no friends at the moment.

The WPC has the eastern half of Kentucky in the slight risk area for 4″+ snows out of this…

Let’s see how the evening models shape up. I’ll share those later tonight. Enjoy the evening and take care.

Monday Afternoon Update

Good afternoon, everyone. Bitterly cold temps continue across the region on this Martin Luther King, Junior Day. Temps this morning hit zero or below in several areas, putting the wraps on one amazing weekend of weather. But, we have no time to rest because more winter weather is on the way by Wednesday.

This is a system that has the chance to throw some decent winter precipitation accumulations on us after a period of rain. That rain breaks out along and ahead of a cold front moving in by Tuesday night and Wednesday. A major temp drop occurs just behind the front, with a lot of precipitation still falling. That results in a change from rain to sleet and freezing rain then snow.

The forecast models vary on how fast the cold catches the deepest moisture. The GFS is mainly central and eastern Kentucky…

The NAM is much faster…

The new version of the GFS is also faster and has much more precipitation showing up…

That is likely overdone, but a situation where the cold catches the moisture quickly is not out of the realm of possibility.

The setup for Wednesday through Thursday morning may require a threat before today is over.

Beyond that, an arctic front brings a period of light snow or snow showers in here Friday. Then it’s game on toward bigger systems diving in and trying to amplify this weekend into early next week…

More Winter Weather On The Way

Good Monday, folks. Bitterly cold temps are with us to begin the week as we wait on more winter weather to blow our way. 3 different systems are tracking toward the state from Wednesday through Sunday and all three may put down accumulating snows.

The first system is along a cold front rolling our way late Tuesday into Wednesday. Temps go above freezing ahead of this front, meaning rain is with us to start. That rain moves in late Tuesday and goes into early Wednesday. As the front moves in, temps take a dive allowing the rain to change to a mix then snow from west to east…

Some accumulations and another ice up are possible late Wednesday into Thursday morning. The best chance appears to be across central and eastern Kentucky.

Behind that system, an arctic front moves in Thursday night and early Friday with the potential for another round of snow. Then another arctic system dives in over the weekend and may bring another snowmaker into town. This system tries to dig in pretty deep. Here are all three systems on the GFS…

The new GFS has a similar look, but shows a 4th system early next week…

So does the Canadian…

While the first two systems this week do bear watching,  the setup this weekend into early next week has a very intriguing look to it.

I will hook you up with other updates later today. Have a good one and take care.
