Some Rain

Greetings from Gilroy, CA.  Questions coming in about rain next week, so let’s get to the latest possibility.  We are Mug ready here.  You?

Dry Sep 26,27 weekend ahead, except for central Vancouver Island.  Temps will remain Fall-mild.  

Next week continues to present some precipitation, with a stretched out rain field approach the coasts of WA, OR & northern CA on Monday the 29th.  Most areas should get a short-shot of steady rain, then showers lasting into the evening.  Tue Sept 30th will begin with another system, which at this time, may hold more moisture and be centered across southern OR to start, before spreading broadly northward.  Model solutions indicate deep Low pressure center (975 mb) that normally brings fairly strong winds inland, however, this time around the storm center will remain well offshore, so winds should remain minimal.  Rain and shower overnight Tue.  That Low will spin a secondary front over the PNW on Wed Oct 1 for additional rain/showers.  By Thu the 2nd, that Low will move towards the NW corner of WA, with an increasing wind field for the Puget Sound, although not too strong.  It should remain showery throughout the night, drying down on Fri Oct 3.  Potato country (southern ID) will be wet mostly on Mon & Fri next week.

The PNW will catch a break in the rain action over the weekend of Oct 4,5.  And, for the early portion of the Oct 6-10 week.  Rain & showers will spread across the entire PNW again on Wed - Fri Oct 8-10.  Colder, too.  East side snow showers possible at higher elevations overnight Thu.  A chilly Fri, with a widely scattered showers, will end the week.

Cumulative precipitation for the periods noted above:  1/2” to 3/4” in the lowlands west side, both WA & OR next week; then another inch or so added Wed - Fri Oct 8-10.  Dry otherwise.  Yes, there has been lots of variance in model runs, however, we have note moderate consistency for next week, and thus, forecast accordingly.
