NWS Forecaster Discussion

Area forecast discussion 
National Weather Service Boise Idaho 
324 am MDT Friday Oct 9 2015 

Short through Saturday...upper level ridging will 
begin to decrease later today as a shallow but strong and fast- 
moving trough approaches the Pacific northwest coast. High level clouds 
continue to cover much of the region this morning...and these 
will be the deciding factor on high temperatures today. Guidance varies 
considerably throughout the short term...both highs and lows...due 
to differences in wind and sky cover. For today...forecast highs 
range from lower 80s in the ec MOS to upper 80s in the sref. 
Tomorrow the differences are even larger...from lower 80s in the 
met to near 90 in the mav. Differences today seem to be due to sky 
cover...while tomorrow they appear to be due to wind. With 
scattered to broken high clouds apparent upstream...went with a 
blend of guidance to allow for periods of sun and cloud. 
Tomorrow...the GFS seems to be too strong with the southeast wind in the 
Snake River Plain...and therefore has temperatures too high. The only way 
this will come to pass is if the upper level trough digs a little 
more than presently forecast and therefore slows down...allowing 
the surface trough to remain in southeast Oregon throughout the 
afternoon. However...with the nature of the instead of 
closed...and the fast flow in which it is embedded...will lean 
away from the warmest solution. In addition...the mav guidance 
results in record high temperatures over much of the area for Saturday 
maximum temperatures...and this pattern does not seem to support it. Finally... 
for overnight lows Friday night...the GFS again has significantly 
stronger southeast winds in the Snake River Plain...resulting in warm min 
temperatures. We again leaned away from the warm GFS/mav solution. 

Long term...Saturday night through Thursday...models agree on 
timing and amplitude of the shortwave trough crossing our County Warning Area late 
Saturday night and Sunday morning. Prefer the GFS which brings 
precipitation further south with this relatively deep and fast moving 
feature. Expect clearing Sunday afternoon following the cold 
front...with highs 10-15 degrees cooler than Saturday and close to 
normal. Low amplitude ridging will bring warming starting Monday... 
with dry westerly flow south of the jet axis. Temperatures will be 5- 
10 degrees above normal. 


Aviation...VFR. Scattered to broken high level clouds. Patchy 
valley fog is possible in the Baker area and west central Idaho 
mountains until about 16z. Surface winds...light and variable. Winds 
aloft southwest to west 10 knots or less up through 10k feet mean sea level. 

Weekend outlook...VFR. Scattered showers mainly late Saturday night 
through Sunday morning over Baker County Oregon and the central 
Idaho and Boise Mountains.
