NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
914 am PST Tuesday Mar 3 2015 


Update...the latest infrared satellite was showing a few clouds across the 
region. Otherwise high pressure will dominate the areas weather with 
dry conditions through the middle of the work week and the present 
short term forecast appears on track for now. 


&& 


Aviation...18z tafs...VFR conditions with clear skies are expected 
over the next 24 hours. Winds will be less than 10 kts through 
tomorrow morning. Perry 


&& 


Previous disc... /issued 415 am PST Tuesday Mar 3 2015/ 


Short term...today through Thursday...a deep northerly flow behind 
a cold front will prevail today over the Pacific northwest. This 
will bring down cold Canadian air into the region. Modified Arctic 
air will brush the County Warning Area with the coldest air staying east of the 
Rocky Mountains. However in any case it will be a cooler day with 
maximum temperature readings only reaching the lower to middle 40s in 
the lower elevations and middle 20s to middle 30s in the mountains. This 
is some of the coldest air seen since early January. The cold snap 
will be short lived however as an upper ridge builds eastward into 
the region over the next few days. Temperatures will moderate each 
day...but nights will be cold due to strong radiational cooling and 
light winds. In any event a warming trend will take place with 
maximum readings reaching the middle 50s lower elevations by Thursday 
with 40s to near 50 in the mountains. Precipitation is not expected 
in the short term period...except possible light snow showers this 
morning over the Wallowa Mountains. Winds will be mostly pressure 
gradient driven today from the north and then they will become more 
terrain dependent starting Wednesday and continuing on Thursday. 
Wind speeds will mainly be from 5 to 10 kts...but there could be 
local afternoon gusts to 15 kts each day. 88 


Long term...Thursday night through Monday night...a middle/upper level 
ridge of high pressure will persist over the NE Pacific and the 
Pacific northwest through the period for dry conditions. As such 
near drought conditions are looking more likely as this very 
persistent ridge of high pressure has been a feature of the 
middle/upper level pressure pattern during this winter season across 
the NE Pacific and the region. Polan
