Longest day of the year, and of course, it has to be the wettest period of the whole month. Go figure.

Cool & damp today through late Saturday.  ⚠️CAUTION:  there is a moderate chance for thunderstorms around SW WA & western OR during this period.  Cold air aloft, peaks of sunshine warming the surface, and boom -> a thunderstorm can form.  Gusty winds, lightning, hail all possible; stay safe!

Indications are that Sunday the 22nd should bring on drier conditions, although temps will run below normal.  

Next week will bring a return to sunshine, with the exception of Thu Jun 26, when a quick moving trough of cooler temps & showers cross western WA.  Temps next week should run in the lower 70s; breezy afternoons.  

The last weekend of June will present as dry, warm & summer-like, with temps topping out in the 80s in most locations; low 90s possible in southern OR and around Burns, OR.

July is now charting to start out dry, with some cloudiness over the far NW corner of WA and portions of BC at times.  Temperatures should run in the normal range for the first week or so.  The 4th?  Well, breezy with a fairly strong onshore flow; dry.  We’ll see.

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.)

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.  

Ah, the heat will soon retreat, leaving pleasant days ahead for, what could be, the rest of June.  ☕️We are Mug ready.

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.  

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.
