Area forecast discussion 
National Weather Service Pocatello Idaho 
207 PM MDT sun Oct 19 2014 


Short term...high pressure ridge will prevail over southeast Idaho 
through Monday evening. Monday morning will be on the cool side 
again with morning lows near or a little above freezing. The lower 
valleys will warm 3 to 6 degrees over Sunday with afternoon south 
winds pulling warmer air in. Low pressure trough will move inland by 
Monday night and bring rain showers to the central mountains before 
Tuesday morning. Associated surface front will reach Stanley about 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. Models are also consistent in bringing sub tropical 
moisture north from Arizona and New Mexico in almost monsoon 
fashion. The nam12 model uses some of that moisture to enhance 
shower activity in the south central and Caribou Highlands Tuesday 
afternoon. With the front pushing into the snake plain Tuesday 
afternoon...it will be on the windy side but short of advisory 
level. Tuesday highs only in the upper 50s to lower 60s. This trough 
moves off to the east quickly Tuesday night with a little wrap 
around moisture and showers lingering Near Island park and Driggs 
Wednesday morning. Receiver station 


Long term...Thursday through Sunday. 
Vast disagreement in GFS and European models in extended. GFS 
flattens flow much quicker and brings moisture into the region the 
entire long term period with a much more progressive pattern. GFS 
brings in precipitation Thursday to central mountains with the main 
trough coming through Saturday into Sunday. European keeps ridge to 
east stronger and keeps precipitation north Thursday through 
Saturday and moves the trough inland on Sunday with no precipitation 
until Sunday at the earliest. For now decided to keep the dry 
conditions Thursday through Saturday and did not jump on GFS 
solution at this time. Kept above normal temperatures through the 
period with the slower movement and European favored.
