Great Ending Possible

Yes, indeed, we have seen a shift in time for the arrival of super-pleasant weather around the PNW.  A great ending for the rather chilly month of May 2025.  Mug up.  Read on.

This weekend will continue on the damp side, after a short break today into early Sat, then another cold air system moves is for increasing rain, possible thunderstorms (mainly over portions of OR) and cool temps.  HOWEVER, Sunday looks to turn mostly dry, as expected.  Windy east of the mountains.

Next week presents the chance for additional moisture arriving sometime Mon May 19, but that system should transit the PNW quickly, leaving cool & mostly dry conditions, along with some cloudiness, esp around the Puget Sound.  —> Eastern basins, esp OR, are likely to have WINDY periods on/off the whole week.  Other than a slight chance for a widely scattered shower or two over the Puget Sound on Wed May 21, we’ll boldly forecast a mostly dry and WARMING week after Monday the 19th.  In fact, the coming US Memorial Day Weekend is trending exceptional!

Earlier solutions presented by the wx models had a damp holiday charted, then the dampness shifted a bit to just part of the weekend: however, now the charts indicate a ridge of High pressure building over the entire PNW (BC, too) as the weekend progresses.  Furthermore, in our previous discussion, we ’saw’ a heat-up period after the holiday showing on the charts.  Well, that continues to be the scenario except that the time of arrival has shifted forward to the Memorial Day weekend.  Excellent wx for all outdoor activities honoring those that gave their life for our Nation (and, yes, for the campers and BBQ events, as well).

Bottom line: the sky will clear and the sun will shine as Memorial Day weekend gets going.  Temperatures could pop well into the upper 70s to mid 80s (warmest in the southern sector).   Also, the short work/school week after the holiday should be warm.  Temps also looking up - into the 80s, even low 90s in southern OR.  (Mid-level moisture is on the charts, riding north around a Low over NV / UT in the May 28-30 period, which could set off thunderstorms east of the Cascades).  Overall, a great ending for May.

June.  Trend is for sunny, warm conditions to continue as June opens, as the Pacific High may position favorably for pleasant PNW weather.
