A Couple Days

Looks like only two ’summer-like’ days are on the charts out of the next seven.  Do they fall on a weekend?  ☕️ Mug up for the answer.  

Onshore flow has helped keep a pesky marine cloud deck around, holding down temps this past weekend, and today.  Not bad, just typical PNW April weather.  We have a weak front that will quickly pass over tonight into early Tue, so areas roughly north of Portland can expect a bit of moisture.  Not much, but enough to dampen the ground.  THEN, Wednesday & Thursday this week will be the 2 ’summer-like’ days out of the next several.  Sunshine & warmth, esp over western OR, which could top 80 inland on Thu; upper 70s possible around the Puget Sound, esp the southern portion.  Friday does NOT look too bad, as the next chilly, damp system may hold off arrival until overnight Fri into Sat morning.  Temps on Fri will be down a bit from Thu, but pleasant & a tad muggy, ahead of the cold front. 

The first weekend of May looks on the chilly side, with periodic showers broadly spread around the entire PNW; clearing some on Sunday May 4.  WINDS will pick-up significantly over the eastern basins of the PNW this weekend, with the strongest located over SE OR & potentially Spokane.  Blowing dust could an issue.  California - generally north of Pt Conception - will turn chilly with some rain/showers & possible thunderstorms in the Sierra Nevada range.  

By the time next Mon, May 5 arrives, we should be out of the broad precipitation mode and slowly warming back up into the upper 60s or so in Oregon; however, an onshore flow is likely to bring a return to the pesky marine cloud deck inland, west of the Cascades.  We do see a weak trough clipping Puget Sound area late Tue through Thu, so mostly cloudy with a chance showers is our ‘call’ for now.  That same trough may hold together enough to bring on clouds and a widely scattered showers over western OR on Thu May 8, as well.  Friday May 9 is trending warmer, with plenty of sunshine in the afternoon.  

The weekend of May 10,11 is looking dry, with partly cloudy conditions under an onshore flow.  Sounds familiar, right?

NOTE:  we do see a possible shift of the Pacific High farther to the NW by May 14 or 15, which, if verified, would usher in warm weather for the second half of May — mid-80s to lower 90s in western OR; warm over the Sound, too.  We’ll see.
