Fall Begins

There are changes in the long-range outlook since our last update.  Best to refill that Mug, Patron. 

End of Astronomical Summer.  The weekend ahead will be dry & mild, with summer ending early Sunday morning.  For Patrons north of Chehalis, a weak system clipping southern BC will usher in clouds and chance for showers late Sunday into Monday; the rest of the PNW should remain dry and pleasant.   Fall Equinox is early Sunday.

For the week of Sep 23-27, Oregon will have dry conditions with mild to warm (80s), temperatures.  A couple weak systems are charting to bring a clouds with scattered showers for areas north of Longview on Wed and again Thu night; dry otherwise.  Northern Vancouver Island looks damp most of next week.  

Go Figure.  You guessed it, the models reverted back to the drier pattern mentioned earlier, dropping the heavy rain next week and the last weekend of September.  Such a swing for planning, but that is the nature of forecasting Nature.  We now see dry weather, other than the few showers noted above, for the entire PNW from now through Oct 3.  In that period, there could be a few days with temps climbing into the 80s, esp in the Willamette Valley.  

Rain.  If (and that is a big if) models are correct, moderate-to-heavy rain will arrive the weekend of Oct 4,5.  Keep your Mug handy, as fall has a way of surprising even the best weather models & forecasters.
