Good Thursday, folks. Rounds of rain continue to push across the region and this trend carries us into the upcoming weekend. This is ahead of a major pattern change on the way next week. A change likely to lead us into a very cold and wintry setup in the runup to Christmas.

Let us start with what’s going on out there today and roll forward. Waves of rain are rolling from west to east across the state with the heaviest rains showing up across the southern half of the state. This is an area that’s already picked up more than 2″-3″ since Tuesday, so we will have to watch for local high water issues developing.

Here are your radars to track the latest round of wet weather…

This round of rain moves away this evening into tonight, but another wave of showers rolls through here later Friday. That will be followed up by yet another round of rain moving west to east later Saturday into Saturday night. This is the system the Canadian had when no other model was showing much at all. The Canadian still has it…

Look at the snow that brings to the Great Lakes and the northeastern part of the country.

Guess who has now joined the party on all that? The GFS…

Remember this trends, folks.

The next system shows up in the form of a monster plains storm system. Normally, a system like that would lift northeastward into Canada, but that can’t happen because of the mega block showing up. Instead, this system gets pushed east into the Great Lakes and may very well pop another low along the east coast as a powerful front sweeps through the eastern part of the country.

The end result for us would be wind driven rain and thunderstorms starting late Tuesday into Wednesday. That would be followed by a rapid temp crash late Wednesday and Thursday as cold air dumps in. With upper level energy spinning through the region late Thursday and Friday and into the following weekend, it would give us a shot at periods of light snow.

This exact scenario has played out on every run of the Canadian Model for the past several days and continues to do so…

The European Model is also on board with a similar outcome…

I suspect we will see the GFS slowly evolve toward this scenario in the coming days. That’s certainly the trend here, right?

That’s also the trend among the Ensembles as well. The Canadian Ensembles have been spitting out some of the coldest solutions I’ve seen from any Ensembles for as long as I’ve been tracking weather… And that’s a while folks. 👴

This goes from the second half of next week through December 23rd…

The GFS Ensembles got the memo and are now similar to what the Canadian Ensembles have been showing for a while. This animation goes through the same time period…

It’s incredibly rare to see Ensembles show that kind of cold on such a broad scale across the country. With the amount of blocking showing up across the northern hemisphere, some extreme events are possible across the good old USA for the second half of December into early January.

It’s way to early to tell exactly how this plays out for Kentucky, but I believe this pattern produces some snowfalls before Christmas. It may also produce some crazy cold shots, too.

Updates will come your way later today. Have a good one and take care.
