NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service Pendleton or 
330 PM PST Friday Feb 5 2016 


Updated aviation discussion 


Short term...tonight through Monday. Upper level trough and cold 
front are moving into the Pacific northwest this afternoon. Clouds 
are increasing with some light precipitation showing up just west 
of the Cascades. This system will move through the forecast area 
this evening and tonight with a period of rain and higher elevation 
snow. Locally breezy south winds ahead of the front this afternoon. 
More widespread breezy west winds this evening and overnight after 
frontal passage. Snow levels fairly high with much of the precipitation 
falling as rain at first...then cold advection will change over to 
snow in the mountains before ending late tonight. Upper ridge 
starts building in Saturday with clearing skies. The ridge will 
strengthen Sunday and Monday and be centered over the region. 
Skies will be clear to partly cloudy. Will likely have patchy fog 
develop in the Columbia Basin and valleys each night. The airmass 
will warm rapidly with freezing levels approaching 10k. Highs will 
be well above normal. 94 


Long term...Monday night through Friday...high pressure will be 
over the region through Wednesday...keeping the weather mild and 
dry. However...patchy fog and freezing fog will be possible in and 
around the Columbia Basin...and especially in the Kittitas Valley 
the High Mountain valleys of eastern Oregon...including the Wallowa 
valley. Then on Wednesday night...a cold front will approach and 
rain will start to cross the Cascades. There are timing differences 
among the models with the 12z European model (ecmwf) bringing the front through on 
Thursday morning...but the GFS and Canadian hold off until Thursday 
night. Have leaned toward the slower solutions...which is in line 
with the previous forecast. That said...do not expect rain to reach 
eastern portions of the forecast area until Friday morning. An upper 
low will then keep showers going through Friday evening. Snow levels 
will be above 5000 feet through Friday...then fall to between 4000 
and 4500 feet on Friday night. Cobb 


&& 


Aviation...00z tafs...S-SW winds will increase this evening as the 
next cold front moves into the region. Mostly middle and high clouds 
are expected before ceilings lower to 4-7 k feet this evening...with a 
period of light rain showers after 02z. A well mixed atmosphere with 
the passage of this front...and increased winds...should keep fog 
from redeveloping Saturday morning. The strongest winds will be 
overnight...decreasing during the day Saturday. 82
