Generally, PNW wx for the next couple of weeks should remain calm, with marginal, spotty precipitation.  Here’s the latest.
Mild temperatures this week across the region, with a 'parked Low’ spinning off the coast of northern CA that may send a few showers over southern OR & northern CA.  WINDS will kick-up in the far eastern zones, esp Idaho, as a chilly High pressure dome drops into the U.S. heartland, while the ‘parked Low shifts over ID to bring on rain there.  Patrons in western valleys will enjoy 70s with plenty of afternoon sunshine through Thursday.
On Fri Sep 23, a weak disturbance could bring increasing clouds & a slight chance for a shower from roughly Chehalis north.  All that clears out by the coming weekend.  Sunshine & mild temps should continue for an extended period. Where is the rain???
Similar to the current pattern, models track a Low pressure trough off the PNW coast as it moves south during that last week of Sep.  Early on this system was to bring us much needed rainfall.  Yeah, right.  Instead, temps in the upper 70s to lower 80s are possible during the last few days of September.  
The first weekend of October is trending WET, as that new ‘parked Low’ off the coast of CA moves up and over the PNW, hopefully.  A dry ridge of High pressure again reforms to block additional storms from the region from Oct 3 through the 6th, at least.  Oh my.  
????Topical Tropical: hurricane FIONA will strengthen as it continues to move northward, well off the east coast of the US.  Current projections target Newfoundland as the likely landfall point.  In addition, a new hurricane may develop during the last week of September; this one, should it verify, will be named GASTON and quite possibly threaten FL as October gets underway.  Stay tuned.

Great effort, Patrons ! — we are at the $2,660 mark for the Walk to End Alzheimer’s fundraiser this year.  Thank you!  The Walk is this Saturday, the 24th.  Here’s the link:
