A big storm system for the week ahead

Good Sunday, everyone. We have another big storm system slowly working our way over the next several days. This should be the catalyst to kick off a much colder pattern as we head toward Thanksgiving.

Before we get into all the nasty weather, we have one more nice day out there today. Highs will be in the upper 50s and could push 60 in a few spots. Skies stay mostly sunny.

A powerful low pressure system develops across the Rockies on Monday and works into the plains states. Showers will be around late Monday into early Tuesday, but the bulk of the action comes late Tuesday into Wednesday.

Rainfall totals could be impressive, especially across western parts of the region:

Once this storm goes by, we see things starting to really change up. It’s an overall pattern change across North America that’s coming from blocking across the eastern Pacific. That’s something we have seen a lot of since the fall of 2013. To me, it was the driving force that led to our back to back brutal winters here in Kentucky. That doesn’t mean we can expect the same this winter per say, but it’s trying to flex some early season muscle.

As that blocking gets established, the pattern across the United States trends colder and, likely, much colder. The first system to watch for will be a cold front next weekend. That front crosses the region and several models have been showing a low pressure developing along it or just to our southeast. The latest GFS has this…

And the air coming behind that is COLD…

That cold takes us through Thanksgiving week into the holiday weekend. If anything, it may try to trend colder…

Make it a great Sunday and take care.
