NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
240 PM MDT Wednesday Sep 17 2014 


Short term...afternoon temperatures are approaching forecast highs despite 
extensive high cloudiness from upper trough off the Oregon coast. A 
low has formed in the trough near 39/130 which will help split the 
trough as it moves inland Thursday. The low itself will go down the 
calif coast Thursday and Friday while the northern portion of the trough 
shears east into Montana...leaving our County Warning Area in the col between them. 
Weak surface cold front will produce a slight chance of showers in 
our Oregon zones late tonight and in Idaho zones Thursday. Main 
instability for thunderstorms will be in eastern-most Idaho zones 
tonight and Thursday but instability and vertical shear will limit 
mention to only a slight chance. However a better chance will exist 
in southern Twin Falls County and southeastern Owyhee County Thursday afternoon 
and evening where moisture may be entrained from weakening Tropical 
Storm Odile in Arizona. Models have surprisingly little instability 
on our northern border Thursday even though the upper trough will be 
nearby. Drying from the west late Thursday night and Friday. Temperatures 
will be above normal again tonight due to cloud cover. Maximum temperatures 
Thursday will cool 8-10 degrees from today with a few degrees 
further cooling of both min and maximum temperatures Friday. 


Long term... 
Friday evening through Sunday...expect southeast Oregon and 
southwest Idaho to be dry and mild. Highs will run around 5 above 
normal. Skies should be mostly clear or sunny. This is due to an 
upper level ridge currently about 2000 miles west-southwest of Boise...that 
builds northeastward late this week across the pacnw and eventually 
spreads to interior SW Canada as well for the weekend. This leaves 
our area open to influence /moisture instability and lift/ from the 
upper low meandering from our west to S in the short term. Prefer a 
gefs/ec/GFS blend. So the low now is expected to lift north-northeast to the Nevada- 
Idaho border Sunday morning and across light snow shower to S-central Idaho Sunday 
through Monday respectively with scattered mainly mountain showers 
and isolated thunderstorms. Then through Wednesday...temperatures 
will continue to be about 5-7 degrees above normal and a slight 
chance of precipitation will linger in the west central mountains 
from the cutoff low. Models agree that a trough coming out of the 
NE Pacific will move in by Wednesday evening bringing around a half 
an inch of precipitation to much of southeast Oregon/west central mountains/ 
Boise Mountains. Cooler temperatures will accompany the associated 
front...bringing US to just a few degrees above normal. 


&& 


Aviation... deteriorating conditions after 09z but still mostly 
VFR. VFR high clouds this evening except in the Idaho mountains. 
Idaho mountains will have broken middle clouds with isolated thunderstorms. 
Thursday over Idaho scattered showers and isolated thunderstorms 
mainly in the mountains with areas of mountain peaks obscured with 
Oregon and Idaho valleys getting isolated showers and thunderstorms. 
Surface winds strongest over Oregon until sunset from the SW 20-30 
kts then SW to west 15-25 kts. Idaho surface winds south to west 10-15 
kts shifting to west and northwest 10-20 kts Thursday. Winds aloft shifting from 
SW to west 25-35 kts.
