NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
735 PM PDT Thursday Apr 24 2014 


Update...showers continue to develop to the south and east of the 
Blue Mountain foothills. A band of showers is currently moving east 
across the Blue Mountains near Ukiah with more developing behind 
them. Showers should decrease some tonight due to the loss of 
surface heating. There may even be a clap of thunder or two up until 
8 PM (or shortly after sunset) over extreme northeast Oregon and 
southeast Washington mountains. A cold front will continue to 
advance eastward and out of the County Warning Area overnight. However a southerly 
flow will keep abundant moisture over the County Warning Area (mainly the southern 
half) overnight into Friday. Thus will keep showers in the forecast 
through the night into Friday over the southern half of the County Warning Area. On 
Friday afternoon an upper trough axis will move into the Pacific 
northwest which will keep the atmosphere unstable and under a 
continued threat of showers from the Blue Mountain foothills 
southward and over the Cascades. Elsewhere the Columbia Basin and 
the Yakima/Kittitas valleys and the eastern Columbia River gorge 
will be dry due to a downslope flow east of the Cascades. There may 
be a few inches of snow in the higher elevations of the northeast 
mountains overnight and on Friday over Wallowa County as snow levels 
drop to around 4500 feet. However am not expecting enough to warrant 
an advisory. There will be a break in the weather on Saturday and 
then another weather system will move into the region Saturday night 
into Sunday. 88 


&& 


Aviation...06z tafs...VFR conditions will prevail overnight into 
Friday. There may be brief periods of MVFR conditions at kpdt... 
kalw...krdm and kbdn due to showers and lowered ceilings in showers. 
Winds will generally be from 10 to 20 kts this evening...decreasing 
to 5 to 10 kts overnight. Then they will increase again on Friday to 
10 to 20 kts from kdls southward. Elsewhere they will remain from 5 
to 10 kts on Friday. 88

Previous disc... /issued 430 PM PDT Thursday Apr 24 2014/ 


Short term...tonight through Saturday...a cold front associated 
with an upper level trough will continue across the area tonight. 
Showers and thunderstorms will continue this evening across the 
eastern portion of the County Warning Area. As the upper level trough deepens over 
the area tonight...probability of precipitation will increase as moisture from the south is 
transported across the mountains of northeast Oregon. There is a 
chance the these showers will reach the foothills...but not 
anticipating the basin area. Will have to monitor and make updates 
as needed. By tomorrow a better chance for showers to reach the 
basin area. 


Other concerns tomorrow...as the upper level trough centers over the 
County Warning Area...there is the possibility of isolated thunder. The issue is 
that models have a middle level cap at about 650mb. This will inhibit 
towering cumulus to reach the potential for thunderstorms. 
850-500mb temperature differences are around 30 celsius. If enough 
surfaced based heating occurs to break the middle level cap...then 
isolated to scattered thunderstorms will definitely be possible. 


Saturday...as the trough pushes off to the east...showers will 
continue with snow showers above 4000ft. Right now there is a 
slight chance that areas above 4500ft in Wallowa County could 
receive 2 to 3 inches Saturday morning. Have not issued any 
highlight for the area...as other models keep the snow above 
5000ft. Right now the only areas that look to be affected by the 
potential snow...would be sunrise-3 from Joseph to Flora. Weber 


Long term...Saturday night through Wednesday. A storm system will 
take aim on the two state area Saturday night and Sunday with 
increasing clouds and showers before moving east of the region 
Monday. However the unsettled weather will persist into the 
beginning of the week before a ridge of high pressure builds into 
Washington/or Tuesday and Wednesday and drier conditions are expected. 
Temperatures will remain slightly below normal until a warming trend 
is expected toward the middle of the work week.
