NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
954 am MDT Thursday Aug 21 2014 


Discussion...stable and much drier air over Oregon will slide 
into central Idaho while a surface trough...moisture and scattered 
showers/isolated thunderstorms linger across south central Idaho. 
Interesting anomaly gradient in the precipitable water field this afternoon with 
from very dry -1 Standard deviation air over Oregon by noon and +1 
South Dakota over Idaho. With the dry air moderate gradient winds are 
expected over Oregon with the nam12 bufr sounding at Burns 
indicating gusts to 25 miles per hour later today. This is below headline 
criteria. Conditions are in current forecast...so no changes. 


&& 


Aviation...VFR. Isolated showers and thunderstorms mainly south and 
east of ktwf this afternoon. Surface winds generally westerly 12kt 
or less. Winds aloft at 10k feet mean sea level...SW 10-20kt. 


&& 


Previous discussion... 
short term...today through Friday...drier air will follow an 
exiting shortwave trough today...limiting showers and 
thunderstorms to central Idaho zones...to include the west-central 
mountains and western Magic Valley. The rest of the SW Idaho and southeast 
Oregon is dry today in west-northwest flow. An upper low drops into the Pacific 
northwest tonight...tracking to east-central Oregon by Friday afternoon. 
Moisture and lift ahead of this feature will focus precipitation 
development from east-central Oregon into the west-central Idaho mountains and 
S-central Idaho on Friday. Temperatures will continue to gradually 
slide with highs 5-10 degrees below normal today and Friday. 


Long term...Friday night through Wednesday...upper level trough 
will remain over the northern rockies through the period bringing 
below normal temperatures. A closed low moves across our northern 
zones Friday night into Saturday for precipitation across the west 
central and Boise Mountains. Drier air on the backside of the low 
should keep much of southeast Oregon precipitation free. 
Temperatures will fall to about 10 degrees below normal Saturday. 
Dry northwesterly flow remains over the area Sunday as the low 
pressure system exits but will be followed by another moist Pacific 
trough for Monday. Increased probability of precipitation across much of the area especially 
the central Idaho mountains. Models remain split on the trough and 
upper ridge evolution for the middle of the week. GFS remains 
consistent in bringing the Pacific Ridge Tuesday/Wednesday. 
However...the 00z European model (ecmwf) and many of the 00z GFS ensembles member 
keep the trough over the intermountain west through Wednesday. 
Blocking patterns are not particularly handled well so confidence in 
either solutions is low.

Boi watches/warnings/advisories... 
Idaho...none. 
Or...none.
