NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
848 PM MST Thursday Nov 26 2015 

Discussion...update to go colder tonight /10 to 13 below zero/ at 
Fairfield Idaho and Burns Oregon. This due to fresh snow 
cover...light winds...and mostly clear skies...along with current 
temperatures in the single digits around zero. Expect patchy dense fog 
to expand downhill on drainage winds...from the western magic 
across Mountain Home. About a third inch of rain fell across the 
lower Treasure valley and highs there were mild /38-46f/ for good 
evaportaion. So low layer moisture could also form patchy fog and 
stratus there early Friday. Record cold is likely at Burns the 
next two morning - see pnsboi - and possible at Baker City too. 


Aviation...generally VFR. Patchy LIFR fog in the Magic Valley near 
kjer ktwf kmuo and in mountain valleys. Low stratus may develop in 
Treasure valley but low confidence. Surface winds generally variable 
12kt or less. Winds aloft near 10kft mean sea level...east-northeast 25-35kt. 


Air stagnation...across southeast Oregon afternoon mixing 
heights Friday through Sunday will be below 1200 feet above ground 
level and transport winds will be light less than 7 miles per hour. The 
stagnant pattern will bring poor ventilation across southeast 
Oregon through the weekend. 


Previous discussion... 
short term...tonight through Saturday...light snow is still 
occurring in the southeast portion of the County Warning Area...mainly south and east of 
a line from Rome to Mountain Home to Fairfield. This snow will 
continue to diminish as the afternoon and evening progress. This 
drying trend continues tomorrow as the upper low retrogrades back 
into Nevada tonight before slowly drifting east again Friday night 
through Saturday. Clouds will be found across the south and 
east...closer to the low...with mostly clear skies elsewhere. Fog 
will be a problem through Saturday...with snowpack covering much 
of the County Warning Area and especially in valley locations where skies are 
mostly clear. Interestingly...Jerome has fog this afternoon 
underneath a low cloud deck. How long this will last is a good 
question...for now will take it into the evening and let later 
shifts adjust as necessary. Fog is also possible in the Baker and 
long valleys...and around Burns...so those areas have it in the 
forecast for tonight and tomorrow morning. Temperatures will 
depend heavily on snow cover...and we have manually adjusted the 
model guidance significantly more than normal in this forecast 
package. Particularly...the southeast portion of the County Warning Area was 
adjusted downward close to 10 degrees owing to heavy snow pack. 
The differences are not that great at this time owing to 
wind...but as the wind decreases tonight through Saturday...we 
expect this will change. The area around Burns and also Foster 
Flat...both in Harney County...were adjusted downward based on 
actual lows from this morning. We can find no reason for large 
changes Friday or Sat morning compared to what happened this 

Long term...Saturday night through Tuesday. Cutoff upper low is 
expected to continue to spin over northern Nevada/Utah before finally 
drifting east on Monday. No impacts are anticipated...except some 
cloud cover...which may bring some uncertainty to the forecasted 
temperatures. For Monday and Tuesday...models have come into a bit 
of better agreement on a transitional upper high dominating the 
pattern. Temperatures will remain below normal through the period. 

Tuesday night through Thursday...ridging remains over the area 
Tuesday night into Wednesday keeping things dry for the County Warning Area. 
Models start to show some moisture pushing in from the coast 
Wednesday night associated with an upper low that sits off British 
Columbia. Timing is different between models with the European model (ecmwf) 
keeping US drier longer compared to the GFS. Because of the 
differences in timing...confidence still remains low with this 
next system. Kept things on the drier end through the period as 
did previous forecast.
