The weather the next few days won't be nearly as interesting as what we saw last week. The historic storm that buried parts of the Dakota's and Minnesota with record snows and brought the first freeze to my area is now a thing of the past. Despite the more relaxed look of the atmosphere there are subtle things going on that will have a large impact on the Midwest long term.

This long range re-alignment first entered my radar over a week ago when it became apparent that super Typhoon Hagibis was going to make a turn north in the western Pacific aiming its remnant energy towards the Bearing Sea. There's an old forecasting rule a re-curving typhoon is likely to form a downstream trough over the eastern U.S. in the 6-10 day period. That opens the door for cooler air to find its way into the eastern half of the nation. Her'es the turn I'm talking about.

The storm approaching Japan prior to the weekend. Up to 30 inches of rain and many deaths in the northern part of the island.

Now the reversal to an east coast trough is a big change in the pattern because much of September and October the east has been dominated by a strong ridge that's kept temperatures well above normal. That thermal set-up is clearly evident in the departures over the past 45 days.

Finally, the MJO (Madden Julien Oscillation) also sees the change. It is moving from phase 1 where its been for a prolonged period of time into phases 2, 3, and 4. More often than not the MJO signals a pattern change before the models ever do. In this case, I was able to suspect the change even before the MJO because of the Pacifc typhoon. That pattern recognition (one of the things good forecasters pick up on) gave me some added lead time to get out in front of the trend.By seeing the track and intensity of that typhoon I was pretty sure it would be the catalyst to get the MJO moving again.
