NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
230 PM PDT Friday Apr 18 2014 


Short term...tonight through Monday night...weak ridge of high 
pressure will build over the area today and tonight. Temperatures 
will be in the lower to middle 60s today and upper 60s 
tomorrow...before another cold front pushes through tomorrow 
afternoon. Breezy winds and a chance of showers...mainly over the 
mountains will accompany this frontal system. As this system exits 
the area...brief high pressure will once again return Sunday 
morning. Temperatures will be a bit cooler Sunday...but should 
still be a nice day...with highs in the lower to middle 60s. By Monday 
southwest flow will have set in and temperatures are expected to be 
in the 70s across the lower elevations. Moisture will begin to 
spread across the Cascades Monday afternoon ahead of the next cold 
front. By Monday afternoon and evening precipitation chances will 
increase across all areas. For now have not added thunder to the 
forecast...but will not rule it out as a possibility. Expect the 
cold front to push through late Monday...early Tuesday. Weber 


Long term...Tuesday through Friday night...a negatively tilted 
trough will be over forecast area on Tuesday with rain showers 
likely over mountains and a good chance of showers at lower 
elevations. Tuesday night the trough moves into Idaho/Montana for 
decreasing probability of precipitation overnight. Wednesday high pressure begins building 
into the region from the west for decreasing probability of precipitation at lower 
elevations with a chance of showers in mountains through Wednesday 
afternoon. Wednesday night through Thursday night mainly dry 
conditions due to the ridge. Friday/Friday night moisture begins 
increasing in higher terrain for a chance of showers over mountains.

Aviation...00z tafs...VFR will occur over the next 24 hours. The 
ridge axis of an upper level ridge of high pressure offshore moves 
east to the coast by early this evening. Sinking air associated with 
the ridge will keep dry conditions in place east of the Cascades 
throughout the forecast period. The ridge axis will move into 
Idaho/Montana by daybreak Saturday, thus allowing winds aloft to 
back from west to southwest by daybreak on Saturday morning. 
Scattered high clouds will stream through the ridge today with cloud 
bases around 20000-25000 feet above ground level and then lowering to middle levels this 
evening with bases beginning around 15000-20000 feet this evening and 
then lowering to 10000-15000 feet overnight into Saturday morning. 
Saturday afternoon cloud bases will lower and thicken to broken 
7000-11000 feet above ground level. Pressure gradients have weakened this afternoon. 
As a result sustained winds will be 8-17 kts through sunset and then 
early this evening become 6-12 kts for a few hours after sunset, 
then become drainage winds of 4-8 kts by 05z/19th and persist 
through overnight. Wind will increase late Saturday morning through 
Saturday afternoon, becoming 14-20 kts by 20z/19th. Polan
