Very Warm Friday

April 5, 2007

SnapshotA very nice warmup today with perfect offshore flow conditions.  In fact there was just a bit too much easterly wind along the Columbia River from PDX to Troutdale.  Highs in that area were only 68-73 degrees.  Those were the coolest spots in the metro area.  Other areas made it to 76 (at official stations).  We should see just slight warming tomorrow in those areas, but as the east wind dies down tomorrow afternoon near the Gorge, more warming there.  Basically I expect more even temperature coverage for Friday.
There is a problem with my currently rain-free temperature forecast for the weekend.  GFS and WRF now have the upper-level low a bit closer to us Saturday.  It could be a good convective day across the central and southern parts of Oregon.  Both of those models have some rain showers by afternoon over even Northwest Oregon though.  Past experience tells me that’s unlikely, but possible.  I’m also concerned that we will see a major marine push on Saturday night, which could keep Sunday cooler and cloudier than my forecast currently indicates.  I may make a change for the 11pm newscast.  Next week is easy…typical clouds and showers. 

Enjoy Friday, I think Clinton Rockey at the Portland NWS captured the mood well with his Aviation Discussion Haiku:

THE DAY GROWS LONGER…THE MERCURY GOES HIGHER…PLAY HOOKIE FRIDAY
I’m not nearly as creative as those guys, but…
LONG DRIVE HOME TONIGHT…SUNNY AND WARM DAY FRIDAY…CUTOFF LOW THUNDER?
