Happy Fourth of July! Real Summer Arriving

July 3, 2012

The saying is “Summer begins after the 4th of July” west of the Cascades.  Some years we get short summery spells, then brief cool spells in between all through June and early July.  In those years there is no real defined change.

This year will be one of those “switch gets flipped to SUMMER” years:

1.  I have no idea when we’ll see rain again; long-range models have no rain or just a sprinkle over the next two weeks.

2.  Hot ridging over the center of the country shifts to its usual summertime position farther west over the Rockies and Intermountain region from this weekend until further notice.

3.  This leaves the “big” summer forecast challenge: how much morning cloudiness makes it inland and does that mean it’ll be 78 or 88?

Tonight will be quite chilly since we still have a cool airmass in place and clear skies…lots of 40s!  But the midsummer sun will warm us quickly into the 60s for those of you headed out to late morning parades.

I’ll be at the Corbett Fun Fest Wednesday evening.  I have a one hour shift in the evening at the Elephant Ear booth (sugar!), plus some sort of minor emcee duty on the stage around the same time.  Fireworks are the 3rd largest display in the Portland Metro area; they tend to go 30 minutes or so!  Just $5 gets you in the gate in case you’re looking for a nice location to watch the fireworks from.  The full moon should be rising over Mt. Hood at the same time too.
