Going for 16 Days

Posted by Rufus La Lone on

Monday May 8
Couple of damp days and then - bam, HEAT.  Build up that ice supply, Patron.
As noted last week, a Low is positioned just west of Brookings and spinning up moisture from the S-SE.  This typically sets up thunderstorm action over the Cascades & east side, with the chance for a few ‘boomers’ west side, as well.  Some of the showers could be intense.  Western WA & BC should remain mostly dry.  Temperatures everywhere will be mild.
HEAT UP.  Our first stretch of hot weather is on tap for this weekend.  Temps will warm rapidly after Wed the 10th, with a peak high in the series expected on Sunday.  Probably 90 - 90+ in western OR; 80s to 90 on north into southern BC.  The heat will be a bit of a shock to plants & people, so be prepared.  Fortunately, temperatures will begin to cool down a few degrees after Sunday May 14, as the High pressure ridge weakens & shifts.  Still on the hot side east of the mountains.   Model solution vary, however, most resolve to another broad Low across the Gulf of Alaska, re-building the warm High pressure ridge west of the coast (vs right over the top of us this weekend).  For now, we’ll call for temps in the seasonal range (70s) and dry, with morning marine clouds at times, for the week of May 15-19.
The weekend of May 20,21 is trending dry, with an onshore breeze.  Pleasant, actually.  Some precip may work north over the eastern basins during that weekend, or at least during the early part of the May 22-26 period; continued dry & mild for the rest of the PNW as we approach the 2023 Memorial Day holiday weekend.
Bottom line:  Very warm temperatures, mainly this Fri - Sunday, followed by seasonally cooler & continued dry wx through at least May 26.   That’s 16 consecutive days without rain (west side), if model solutions verify.
Repeat from 2008:  “The larger the island of knowledge, the longer the shoreline of wonder.”  (Yeah, a bit mushy, but worth a retake.)
