We have experienced unusual humidity during the past week.  Why?  I will describe what controls the "stickiness" of the air in our region.  But before I do that I will review the forecast, which is quite favorable for this weekend, followed by another warm spell on Wednesday and Thursday.

My Views on Global Warming and Climate Change

 This week the weather will be near normal and relatively dry, but that changes radically over the weekend, as a strong Pacific low center moves in and sticks around in our area.

This podcast answers an interesting question: why is freezing at 32°F? Why not 50 or 0?    And I talk about a return of moisture to the Northwest, with heavy snow expected in the mountains.
