Area forecast discussion 
National Weather Service Pocatello Idaho 
152 PM MDT Monday Oct 20 2014 


Short term...low pressure trough will move inland late tonight and 
bring rain showers to the central mountains before Tuesday morning. 
Associated surface front will reach Stanley about 5-6 am Tuesday. A 
quarter to half inch of rain is possible in western Custer and Butte 
County with the deeper moisture tracking to the northeast. Snow 
levels dip to about 8700 feet...1-2 inches accumulation possible 
between 7800-8500 feet...up to 5 inches on the highest peaks. The 
main disturbance tracks northeast towards Montana...while the 
associated surface front trails across the snake plain during the 
afternoon hours. It will be on the windy side during the afternoon. 
A Wind Advisory has been issued for the lower snake plain. Tuesday 
highs only in the upper 50s to lower 60s. Showers are expected to 
end Tuesday night...followed by a weak high pressure ridge on 
Wednesday with lighter winds and mainly middle and high level clouds 
across this area. Receiver station 


Long term...Thursday night through next Monday night. 500mb 5-wave forecast 
indicates a slow change from between a coastal low and Great Plains 
high with a low amplitude pattern...to troughing over the northern 
rockies and northern Great Basin. Thus expect wetter conditions by 
the weekend with even the longwave developing a trough. Both the GFS 
and the European model (ecmwf) are in fairly good agreement on an upper level 
trough/surface frontal passage Sat night/sun...so have increased 
probability of precipitation and clouds for those periods and the other two surrounding them 
to reflect uncertainty in timing. This should also bring some windy 
conditions...but currently appears below advisory criteria. Messick 


Aviation...incoming cold front arrives shortly after midnight in 
the west and spreads eastward during the early morning. Good chance 
of airdrome closure at ksun Tuesday morning with the amount of incoming 
moisture due to ceiling. Elsewhere...ceilings should stay VFR through at 
least the morning. Visibility should also stay good VFR with only -ra type 
of precipitation expected below 8000 feet elevation. Wind shift with 
the front and very windy conditions expected during the morning and 
early afternoon...though peaking shortly after 21/1800z so included 
in tafs after the 21/00z are issued. Messick
