How is That Pattern Change Coming?

Seems to be on track. Here is the forecast pattern in two weeks with the green area representing low pressure.

Often, when there is a change in pattern in the autumn, there is a minimum of precipitation while the change is in process. That is certainly the case over the next five days.
So, if I have this diagnosed properly, there will be some widespread moisture in about two weeks in the Northwest and Central U.S. There will also be another round of moisture in the Southwest ahead of the primary system.
