National Weather Service Pocatello Idaho 
232 PM MDT Monday Apr 20 2015 


Short term...today through Thursday. Current water vapor imagery 
shows our area under high pressure ridging with an low spinning 
over Alaska. Models show this low to move over northern Idaho 
late Wednesday into Thursday. Expect scattered showers and 
isolated thunderstorms Wednesday afternoon into Wednesday evening 
mainly over the central mountains...Pahsimeroi Mountains and 
eastern Highlands with lingering light showers over the eastern 
Highlands through Thursday morning. Expect snow levels to start 
around 10000 feet before dropping to around 8000 feet by the end 
of the period. Only around 1 inch of snow above 10000 feet is 
expected. Models are showing less showers from the previous model 
run on Thursday with weak high pressure ridging. Expect above 
average temperatures through the period. Wyatt 


Long term...Thursday night through Monday. Somewhat unsettled in the 
long term period. Have at least a slight chance of chance of 
showers and thunderstorms daily...mainly in high elevations. Both 
European and GFS drive through an upper level system in the Friday 
to Saturday time period. GFS is stronger with a wetter solution 
while European moves it through quicker with less precipitation. 
Have highest probability of precipitation in the Friday through Saturday time period. Both 
are drier Sunday into Monday and reflected this on grids cutting 
back precipitation chances a bit.

with winds mainly light through the period.
