Good Wednesday to one and all. It’s another fantastic fall day taking shape across the region as our overall weather pattern threatens to turn unseasonably cold in the coming days. This brings the chance for a freeze in here over the weekend with a colder blast lurking later next week.

Let’s start with a look back at Tuesday’s cold morning…

As you can see, temps hit 32 or below once again and we have yet to have a Frost Advisory. The NWS continues to raise standards on any cold weather products and lower standards on hot weather products and will call any dry spell a drought. Yet, the January-September period was among the wettest on record for much of our region…

Again, dry spells are not the same as droughts, folks.

It’s the same issue with the airport thermometers being incredibly broken. The NWS in Louisville in March told everyone the Lexington thermometer was faulty and warned against using it. They literally told everyone not to use it because it was reading several degrees too warm. It’s October and it still hasn’t been fixed and they now say they won’t fix it. So, we are intentionally skewing official temps several degrees too warm.

Ok, rant over. 😜

Now, let’s talk about where this weather pattern is going.

It’s awesome out there today and that will continue into Thursday as temps climb to above normal for the first time in a long while. Winds will be gusty ahead of a strong cold front dropping in here later Thursday night into early Friday. The timing on the arrival of this front is slowing just a bit, but the air behind it continues to be very cold. Highs over the weekend range from the upper 50s to middle 60s with partly sunny skies. Lows will likely drop to freezing or below in many areas either Saturday morning or Sunday morning, or both.

The Canadian continues to have a good handle on the overall pattern and temps…

There’s another big time dip in the jet stream developing early next week across the Rockies and this will spread eastward later next week. Again, the Canadian has the best handle on this…

The EURO has the first to sniff this out, but the bias of the model of holding energy back in the southwest appears to be coming into play right now…

That will correct itself in time.

The end result in such a setup would be for a healthy fall storm system to impact us with needed rains later next week. The evolution of this is still to be determined and the models are still gonna waffle a lot in the coming days…

EURO

You can see how the EURO holds that system back in the southwest too long. The EURO Ensembles and EURO Control have a different look and eject that trough out much quicker.  Here’s the EURO Control showing that coming out with a follow up deep trough toward the end of the run…

The GFS goes back and forth with even finding this first trough, but the late Tuesday run shows the trough well and also has the follow up trough several days later…

And, for the first time this season, we have the GFS long range with fantasy flakes…

Lock it in… Right? 🤣🤣 Obviously, I post that for fun and to hopefully get a head start on living rent free in the heads of a few other weather folks. 😉😏

Make it a great day and take care.
