Nice weather gives way to a colder setup

Good Thursday, everyone. We continue to be in the midst of a gorgeous fall weather pattern across the Bluegrass State. It all changes late this weekend and early next week as rain increases. This leads us into a cold setup for the closing week of October.

Highs Thursday will hit the 70-degree mark in many areas, with sunny skies rolling on.

Those numbers will climb Friday and Saturday, with highs from 70 to 75 for much of the region. Enjoy these nice days, because those changes roll in later Sunday.

A storm system pushes into the region, with showers and storms increasing from west to east late Sunday. This system then rolls on top of Kentucky by Monday, bringing the potential for very heavy rain. Once it goes, through, check out the cold shot coming in behind it:

Highs in the 40s will be possible by Wednesday. It might also produce a few snowflakes across the Appalachian Mountains.

As that system departs, a colder blast of air dives in by next Friday and Saturday:

Can that get some snow flying across areas of the Ohio Valley? It’s too early to tell, but the air is frigid for late October.

Check out both cold shots from the European model:

The European ensembles (51 members) are in strong agreement with the operational run:

The European model shows significant blocking going up across Canada into Greenland, allowing for a deep eastern U.S. trough to develop:

As we mentioned earlier this week, a typhoon in the western Pacific is forecast to recurve in the coming days:

Lan will become a super typhoon as it heads toward Japan then curves northeast. That kind of track usually signifies a deep buckle in the jetstream across the eastern half of the United States.

Make it a great Thursday and take care.
