The GFS giving it up a bit…

May 14, 2009

A very short post because I took a nice long bike ride, then ended up on the phone discussing some possible big changes in the Portland TV weather people “scene”.  How’s that for a tease?  Basically I was doing some weather gossip.  Don’t worry, it doesn’t affect anyone here at FOX-12.

Well, the 00z GFS has suddenly veered towards the ECMWF solution for Monday-Tuesday, keeping upper-level heights much higher, 850mb temps warmer, and digging an approaching trough much farther offshore.  It’s really obvious when you look at the 12z, 18z, 00z 500mb height comparison for Monday afternoon.  This link is a good place to view it.  I notice the 850 mb temp over PDX is 15-16 now compared to 5 Monday afternoon on the new GFS.  So I bumped Monday back up to 80, which could be low.  We’ll see.  Okay, time to slather the makeup on again…Mark Nelsen
