Good Wednesday to one and all. As summertime puts in some overtime, we start to look ahead to the rest of fall and winter. If you’re sick of the heat, you’re probably going to like what some of the seasonal models are finding for the months ahead.

In the short term… it’s hot through the start of the weekend. That’s when a “backdoor” cold front drops in from the northeast and knocks our temps down closer to normal on Sunday.

Another cold front moves our way on Monday, and this is where we find some model split going on. The earlier run of the GFS brought a cold front through here with a lot of energy hanging well to the southwest…

The latest run decided not to bundle so much energy in the southwest, and now has all that system totally cutting off around here…

That would bring a much better threat for showers and thunderstorms to go along with a prolonged period of cool temps. Watch this upper level low hang around for days and day…

That’s actually similar to what several models were saying might happen a few days ago.

The European Model isn’t a stout as the above GFS, but has the low cutting off across the Midwest into the Ohio Valley…

I’ve been posting some recent snow runs from the CFS and they have been showing North American snow increasing a little early. A similar run from an overseas model shows something similar through the first few days of November…

All seasonal models should be taken with a grain of salt, but one can certainly gather some useful forecasting information from them.

I have been showing the warm pool of water across the Gulf Of Alaska and how it is still going strong. I first talked about this in the fall of 2013 and then honed in on it as the likely driving force for the following harsh winter. That same warm pool was there for the following harsh winter. It was there last year, but was the super el nino muted it’s potential.

That warm pool continues to show up on the seasonal models for the winter ahead…

The latest temperature run from the WeatherBell CFS goes cold…

While that model does show some pretty big changes from day to day, I have noticed more and more days showing a colder look. Again… take it with a grain of salt, but also as something of a learning tool.

In addition to the past few winters, other analog years showing up: 1983-84, 1995-96 and 2000-2001.

Have a wonderful day and take care.
