Monday June 10

A fair mix of weather ahead; quite seasonal.  Let’s enjoy a morn’n bev and get the week going - - -

Pleasant conditions in store this week, with morning marine clouds pushing inland, at times, burning off in the afternoon.  The Puget Sound will have mid-level clouds moving overhead Tue evening (showers over N Vanc. Is) and early Wed.  OR & ID conditions just fine. 

By the coming weekend, we can expect increasing clouds and chance for some showers over the Puget Sound Fri night, then expanding over OR and SW WA by late Sunday and into Monday.  Monday & Tue next week are charting to be our wettest period for the balance of June.  Quarter-to-half inch cumulative precip west side is probable.  Outside chance for a few showers around the 28th (a cold front drops down the BC coast), but that is ‘on the edge’ of our model’s view right now.

Onshore flow will hold temperatures in the moderate range.  For now, it looks like a HOT wx pattern may return around Jun 20-25.  We’ll see.

Standard June weather ahead --> meaning a few toasty days, along with some cloudy days with chance for showers.  

• Warm-to-hot for the next couple of days, with cooler onshore push starting Sunday.  
• Pleasant next week, with clouds possible over the Puget Sound on Tue; sunny elsewhere.
• Next chance for showers remains during the weekend of Jun 15,16; definitely cooler.  
• Week of Jun 17-21 starts with some cloudiness (slight chance for showers) & periods of sunshine; turning warmer after the 19th.
• Weekend of Jun 22,23 is trending dry & warm.

🎓 Congrats to all the Graduates in the great PNW, both high school & college!

Plenty of dry wx coming, with a pleasant mix of temperatures.  Let’s take a peek ahead.

Soils are drenched and the air is cleansed of pollen, for a couple of days, at least.  The dry pattern arrives by Wed, with clearing from south-to-north as Tue unfolds.  There will be showers Tue, with most of the precip falling north of Portland.  Overall, temps will remain mild through Wed.  The ‘heat-up’ begins Thu - with some of the warmer temps of the season possible on Fri - esp over western OR.  Expect 80s in most locations, with 90+ possible south of Eugene.  BC catches a rain-break, as well.  Enjoy.

Next weekend looks pleasant, with temps tapping down a bit as an onshore flow increases on Sunday.  Sat will be the warmer of the 2 days.  The onshore flow pattern will hold into the following week, so even though no rain is in our forecast, temps will be mild; cloudiness possible over the Puget Sound, north, as a very weak trough moves overhead on Tue.  Late week we see a cool air mass beginning to drop south over the eastern Pacific, opening the door for increased onshore breezes & somewhat cooler temps.  Morning ‘marine cloud deck’ possible, with afternoon sunshine inland.

The cool Low pressure ‘cell’ moving towards the PNW coast late next week (Jun 13,14) is currently modeled to finally push onshore over southern OR by the weekend of Jun 15,16, ushering in a SW flow and moisture, esp over the eastern basins and Idaho.  This pattern typically means WET and rather stormy wx across eastern regions of the PNW; clouds and showers are also possible for west side locations.  Temps on the cool side for June.  (This is a fairly ’new’ solution on the charts, so the Low may remain far enough offshore to keep the west side dry, with moisture training east of the Cascades.)  

Warmer weather possible as the ’second half’ of June get underway.  So for now, we see pleasant temperatures with muggy humidity levels the week of Jun 17-21.  Although, continued Damp east side!

Warm-up coming after the ’New Month’ storm drenches the region.  Refill time.

Pleasant conditions across the PNW today through most of Saturday.  Mild temps.  Clouds will begin to roll in Saturday over the Puget Sound, with RAIN arriving by Sunday morning across the PNW.  

The ’New Month’ storm will be a real soaker for all of the PNW.  Eastern basins will also get precip, at times.  Expect the steady moderate-to-heavy rain to continue through Sunday night. Blustery!  Monday morning looks wet, as well, although the main front will have passed to the east.  A secondary band of rain may arrive later Monday into early Tue.  Most of the precip this time will fall over areas north of Salem.

Clearing begins late Tue, with a rapid warm-up for the entire PNW by Thu.  (Patrons in southern BC and NW WA may have lingering clouds on Wed Jun 5.)  Temps will pop into. the 80s, maybe a few 90s in the usual hot spots.  The warm pattern will hold into the weekend of Jun 8,9 — although models draw moisture up from the south over the eastern basins, combined with an onshore push of ‘air conditioning’ for western valleys.  Overall, it should be a mostly dry weekend.  

For Jun 10 - 15: continued moisture over eastern OR into ID, with increasing chance for thunderstorms to the east & over the Cascades. Some storms may move out over the Willamette Valley late week.  It will be rather warm and MUGGY, esp for OR.  Patrons in NW WA are likely to remain somewhat cooler, with an onshore wind picking-up late week.  

Generally dry & mild for the weekend of Jun 15,16.  

🇺🇸 Memorial Day 2024 🇺🇸

The weather for the next 17 days (through June 12) is generally split between two zones, if you will.  1) Puget Sound, southern BC, Vancouver Island; 2) south of roughly Chehalis and east of the Cascades, both WA & OR, along with ID.  Here’s the rundown, as of today, May 27.

1) NW WA area & BC.  ☔️ Cloudy & wet at times every day except:

• Dry today, May 27
• Dry this coming Thursday - Saturday, May 30 - Jun 1
• Dry Fri - Sunday Jun 6-9.  (STORMY east side of WA & over ID on Fri & Sat Jun 7,8.)

2) S of Chehalis & east sides.  ☀️ Sunny with mild-to-warm temps every day except:

• Wet tomorrow -Tuesday & early Wednesday May 28,29
• Wet Monday & Tuesday Jun 3,4 (mainly cloudiness south of Salem
• Wet Monday - Wednesday Jun 10-12. 

For all the PNW - the Jun 7-9 period could be the warmest consecutive run of days thus far in 2024.  Early yet to peg this forecast, as models have inconsistently hinted a ’summer ridge’ building into the region, from the south.  Stay tuned.

Bottom line — over the next 2 weeks, the Puget Sound corner of the PNW looks to be more wet than dry, with the opposite pattern for areas south of that zone.
