Wet Weekend Ahead

Posted by Rufus La Lone on

Monday June 16
A couple of wet days are now in the works, with continued mild temps holding on through the rest of June.  Here’s the latest outlook.
This week will remain dry until Fri, except for the slight chance for showers over the higher elevations of NW WA & southern BC.  An afternoon onshore NW breeze will also be in play.  When the Summer Solstice arrives this Friday, so too will be a cold front moving down the coast of BC; the front will be strong enough to set off showers on Fri and steady rain this Saturday for the entire PNW.  Temps will cool down into the 50s, for a rather chilly June weekend.
Next week will bring back dry conditions and sunshine, with morning marine clouds at times.  A weak system may clip the northern corner of the PNW on Fri the 27th, but right now, models do not indicate this one to be all that damp, mostly a cloud event for NW WA. The final weekend of June 2025 also looks dry, but on the cool side of summer.
In the long-range view, the first few days of July are trending WET.  (We’ve seen that ‘show' many times -> damp & cool until after the 4th of July.  Plenty of time for models to give us a clearer picture.)

An Adjustment

Posted by Rufus La Lone on

Friday the 13th
🎓🎓 We tip our Mug to all of the Graduates celebrating their educational accomplishment the next couple of weeks.  🎓🎓
A cooler wx pattern is now in place around the PNW.  Let’s look ahead for the rest of June.
We noted in the last report that the balance of June 2025 was charting as pleasant & dry.  An adjustment in that outlook is now charting to begin later next week, as the chance for some precipitation has been added to the forecast.   A rather stationary upper-level Low has been parked over the Alaskan Panhandle, ushering in the onshore flow, morning marine clouds & cool temps that we are experiencing now.  This should hold through the weekend and through Tue Jun 17.  
It looks like that Low will slowly shift farther south, opening the door for slightly cooler temps, more cloudiness and showers, esp for the Puget Sound.  Wednesday the 18th could present such a change, with western OR getiing in on the action as next week ends.  The Summer Solstice - next Friday Jun 20 - looks generally dry, but with the chance for a few stray showers.  
The weekend of Jun 21,22 currently charts as mostly dry, but cooler than normal for June.  For this forecast, we will emphasize that Mon & Tue Jun 23, 24, could be the wettest period between now and July 1.  
It’s understood that all of the above could change, depending on the position of that upper-level Low - so keep your Mug handy for updates.

Pleasant Days

Posted by Rufus La Lone on

Monday June 9

Ah, the heat will soon retreat, leaving pleasant days ahead for, what could be, the rest of June.  ☕️We are Mug ready.
Toasty again today - mostly in the 90s region wide.  On Tue, temps will moderate to the cooler side by just a few degrees, with additional cooling arriving Wed on through the coming weekend.  In fact, it may be a bit chilly Sunday morning Jun 15, before warming into the 60s.  Other than the chance for morning marine clouds, it should be sunny each afternoon through the weekend.  Onshore breezes.
Next week will present a continuation of pleasant temperatures and dry conditions.  Temps should range in the 70s to low 80s, with the warmest being across the southern zones, both sides of the Cascades.  The Summer Solstice - the longest period of daylight of the year - on Fri June 20th is charting as pleasant.
The pleasant afternoons will also last on through the weekend of Jun 21,22.  In fact, for the past several model runs, dry and pleasant days look to hold until at least Jun 28 or quite possibly the rest of the month.  Pleasant days.

Possible Heat Wave

Posted by Rufus La Lone on

Monday June 2
Greetings, Patron.  Simple forecast today.  Iced Coffee may be needed soon.  Read on.
We see an extended DRY pattern on the charts, so don’t expect any precipitation from today on through Sat Jun 14th.  
For this week, temps will remain mild, mostly in the 70s, with a rather brisk afternoon NW wind (like the past couple of days).  However, that will begin to change this coming weekend.   The strong onshore flow will weaken, opening the door for the warmest temperatures of the year, to date.  Upper 80s to lower 90s begin Sunday Jun 8 over western OR, as a classic summer ‘heat low’ builds north from CA.  
The heat will build north into NW WA & BC during the week of Jun 9 - 13.  Temperatures will top triple digits in southern OR / east side; 90s highly probable up in the Puget Sound region and maybe even southern BC.  The Willamette Valley could reach the triple digit mark Mon or Tue, Jun 9,10.
As a reminder, we use the traditional definition of a HEAT WAVE as 3 consecutive days with temps above 90 F in the shade.  That said, we cannot say for sure just yet if the forecast heat-up will last 3 consecutive days in the NW corner of WA, but for western OR, it looks quite probable.
Dry, turning HOT after Jun 8th; cooler by Thu or Fri Jun 12,13. Showers possible Sunday Jun 15th.   
—> We will be in Minnesota this week, so no forecast on Fri Jun 6.

Gateway to Summer

Posted by Rufus La Lone on

Friday May 30
Ah, Summer is nearly upon us, with schools ‘letting out’; graduates receiving diplomas and vacations begin.  What about wx around the great PNW as June - the gateway to Summer - gets underway this weekend?  Mug time.
Pleasant weekend on tap, although a weak cold front will drape some clouds over the NW corner of the region, and the usual chance for a shower, mainly north of Chehalis.  Mild temps after today’s (Friday) short-term ‘heat up’ into the 80s in most locations.  Sunday should be dry, with some clouds here & there.  Westerly winds will pick-up notably in the Columbia Gorge, and generally across much of southern OR, east & west.
Next week looks dry but a tad on the cool side given a rather strong onshore flow.  Fine weather, actually.
The weekend of Jun 7,8 trends as dry, with temps warming up several degrees as the onshore flow weakens a bit.  
Model runs have hinted at a short period of warm wx beginning to develop by Mon Jun 9, as temps could pop into the upper 80s, even teasing 90+ in the usual hot spots.  It may only last until mid-week, with much cooler air moving in from the NW by Wed or Thu, Jun 11,12.  We’ll see.  Either way, limited precip from that cold front; we don’t see any notable rain/showers throughout the first 15-18 days of June 2025.
The extended dry cycle for June, should models verify, will be favorable for ag operations, although water managers will be kept busy moving lines.  Plant disease pressure should be low, as several crops reach or approach harvest.  
A peek at tropical action presents the chance for the season’s first named Atlantic/Caribbean storm, ANDREA, to form around June 7 south of Cuba.  Pacific hurricane action has already started, with tropical storm ALVIN spinning well south of Cabo.
