Turning Colder but Dry

The weather pattern is looking much quieter for the rest of November 2023.  A weak Pacific front will move through the area on Wednesday, just before Thanksgiving.  This front is coming from the northwest, which is not favorable for precipitation for locations north of Spokane.  And since the system is weak, precipitation amounts will be light.  Although the timing of the precipitation is during the morning hours (when snow would be favored), the atmosphere aloft is going to warm up before the front arrives.  So precipitation type should be rain for the valleys.  Here's one model's forecast of the precipitation amounts for Wednesday.

This weather system will move into the Great Basin for the end of the week.  Meanwhile, very strong high pressure will develop along the west coast of Canada.  This pattern will do two things.  First, Pacific weather systems will have to go around this high pressure, keeping the Inland Northwest dry for several days, possibly through the end of the month.

But the position of this high pressure will also cause our low-level wind to shift, coming from the northeast.  This will be colder, drier air into our region.  The wind will be most noticeable on Thanksgiving.  When the winds let up, nighttime temperatures will drop into the teens with daytime highs only in the mid 30s.

This isn't a strong arctic front.  So don't expect a deep freeze.  On the positive side, this pattern will also mitigate fog and low clouds for a few days.  So look for sunshine Thanksgiving day through at least Saturday.
