Gateway to Summer

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.
