Rain Returns

February 20, 2009

Snapshot  I borrowed this info from Jesse (the one in Orchards).  He found that we haven't had this many 32 degree nights at PDX so far this decade.  Drew and I were a bit surprised, since we had lots of split flow and clear skies for a couple winters in the early 2000s.  BUT, the big cold spell in December really helped the numbers add up this year.  By the way, I credited you each time I used the info Jesse.

The big change is the return of rain this weekend.  Freezing levels are going to be quite high through early Monday due to the mild southerly flow…forget skiing for Sunday.

I'm about out of time this evening due to keeping my eyes on another tv show (BSG) right now.  A change towards cooler and wetter weahter is on the way for later Monday through next Friday.  There seems to be very little moisture Wednesday through Friday until another trough digs in by Saturday.  Earlier GFS runs were wildly cold from that point forward into the first week of March.  I notice the 00z is more reasonable with occasional low snow levels during that time, but no big snow events for the lowlands.  As we all know (especially after last year) it's quite possible to get snow to low elevations in March, but sticking snow IN THE CITY only seems to happen maybe once every 5-10 years.  I think I've only seen it 3 times in my entire career which goes back to 1991.  I'm sure someone can correct me if I'm wrong, but it was only 1999, 2006, and 2008 when we had widespread low elevation snow here in the metro area in March.  Each of those times I think only a trace of snow was recorded at PDX…Mark Nelsen
