Blue Skies Return

March 11, 2009

Moonset_LarryFilz  Larry Filz sent me another very nice picture today…he was up early (at least for my schedule).  He caught the early morning full moon setting behind the West Hills as just a few puffs of stratus or fog floated above the Willamette River.

Today was a great day with tons of bright sunshine.  I still had 3" of snow at my home this morning, so it was a bit blinding inside the house with the sun plus snow cover.  A dry east wind is blowing as expected, bringing dewpoints down into the lower 20s and teens.  No significant changes for tomorrow except a warming airmass should push our temps up 8 or 10 degrees.  A few more degrees of warming for Friday as the east wind dies down.  In fact the wind goes light southerly late in the day.

The big change is Saturday as clouds and solid rainfall move in.  This is a change to wet southwesterly flow.  Models disagree on how close the new Western USA ridge will be to us.  The ECMWF has it closer with much higher heights…warm enough to give us a 70 degree day.  The GFS insists that the conveyor belt of moisture will sit over or just north of us.  We have decided to stick with that solution in our 7 Day forecasts.  Either model  is mild though…Mark Nelsen
