Nice Weekend, Then Cool Week Ahead

July 7, 2011

It was a forecast bust north of Salem today since the clouds lingered far longer than expected.  Even some light drizzle in spots eastside, although that sure wasn’t a surprise.

We have real quiet weather on tap for at least the next 5 days with a thinning of the marine layer tomorrow through Sunday.  That means far more sunshine all three days; Saturday and Sunday look sunniest and warmest.  Then an increase in onshore flow Monday and Tuesday as an upper-level trough approaches.

The big story is still the unseasonable cold trough forecast to sit over the West Coast from next Wednesday until further notice.  It is unusual to see this in mid-late July, and even more unusual that it’ll sit overhead for more than a day or two.  Models don’t show much rainfall, but I have a feeling we’ll see them “moisten up” the next few runs.  Expect at least SOME showers later next week.  As a result, I see no chance for temps above 80 degrees for at least the next 8-9 days!  The average high temperature in Portland reaches 80 next Friday and stays at/above that level through mid-August. 

I will be off work now until the 18th on vacation…nice timing to enjoy the “summer” weather next week eh?  If it gets too bad I’m heading east of the mountains!  It should be warmer over there at least. 

So probably no more posts over the next week.
