NWS Forecaster Discussion




Area forecast discussion...update 
National Weather Service Pendleton or 
349 PM PDT Wednesday Apr 1 2015 


Updated aviation discussion 


Short term...tonight through Friday night...isolated to scattered 
showers continue to develop across the area this afternoon. The 
instability driving these showers has the potential to be locally 
strong enough to cause stray thunderstorms as well. Expect these 
showers and any storms to persist into the evening. The 
thunderstorms should end around sunset. Northwest flow will keep 
some showers going over the interior mountains and near the Cascade 
crest overnight into Wednesday. Snow levels will remain low, but 
accumulations will be light and localized. Expect to see decent 
clearing over north central Oregon and south central Washington 
after sunset. This clearing, combined with a dry air mass and 
decreasing winds, will lead to good radiational cooling. Overnight 
low temperatures in the Yakima Valley, Kittitas Valley and north central 
Oregon are expected to run between 28 and 34 degrees. Though zone 
coverage of freezing temperatures in these areas will not be complete, 
issues for sensitive vegetation will still be possible. Thus have 
issued freeze warnings for the above mentioned zones. Another 
Pacific system will approach the region Friday. Precipitation will reach 
the Cascade east slopes Friday morning and the northeast Oregon 
mountains by Friday afternoon. The system's cold front will swing 
across the region Friday night bringing varying precipitation chances to 
much of the area. 90 


Long term...Saturday through Wednesday...an upper level low will 
slowly move southeastward onto the Pacific northwest coast and across the 
region through the forecast period. Unsettled weather will occur as 
a result with a chance for showers and mountain snow showers 
expected through Tuesday over the two-state area. As the upper 
level low approaches the region Sunday afternoon and evening...middle 
and upper level cooling will allow for some instability over central 
Oregon and portions of the John Day Highlands. Have retained the 
slight chance of thunderstorms from prior shift with some 
adjustments based upon a blend of model guidance instability 
parameters. The upper low will open up on Monday and dig southeastward 
across southern Oregon and northern California through Tuesday night 
with the most favorable dynamics in our forecast area favoring 
central Oregon. Sufficient instability remains on Monday to 
continue a mention of a slight chance of thunderstorms through The 
Highlands of central to northeast Oregon. A shortwave ridge will 
build in behind the trough as it exits the area on Wednesday 
heralding a start to a warming and drying trend. Daytime high 
temperatures during the period will be in the lower 40s to lower 50s 
along The Highlands and near 60 in the lower Columbia Basin Saturday 
through Monday. High temperatures will gradually warm a degree or 
two per day Tuesday and Wednesday. Low temperatures will be below 
freezing each night along The Highlands of Washington and 
Oregon...and near to slightly above freezing in the lower Columbia 
Basin. Bieda 


&& 


Aviation...00z tafs...VFR conditions will prevail during the 
forecast period. Passing convective showers with ceiling at or above 6k feet above ground level 
will continue through 02/04z...with best chance maintained at sites 
with a vicinity mention given the hit or miss nature. West winds 
between 10 to 20 kts with higher gusts will continue through sunset 
tonight before dropping to 5 to 15 kts. Gusty west winds between 10 to 
20 kts will return after 02/18z. Otherwise...ceiling will gradually rise 
as storm system moves out after 02/04z. Bieda
