Warming Up

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!
