zonal flow aloft today. Winds will be breezy to moderate especially 
across the Arco desert where a wind advisory is in place for gusts 
of 45 mph. A lake wind advisory is in place this afternoon for the 
American Falls reservoir where southwest winds of 20 mph sustained

in tonight. Sunday expect a relatively warm day with daytime 
temperatures around 8 to 12 degrees above normal. Expect near 80 
degrees across our southwest valleys and 70s in valleys elsewhere 
with mid to upper 60s for the mountains. The high pressure quickly 
breaks down as a trough moves through the Central mountains in the 
early evening. The Storm Prediction Center (SPC) has the Central 
mountains in a marginal outlook for severe thunderstorms. For the 
Central mountains expect scattered showers and thunderstorms 
bringing a chance of small hail and strong outflow winds. Isolated

Southern Hills/Albion mountains Sunday evening as well. Wyatt

Tuesday and Wednesday with dry conditions expected and highs in
the 60s mountains and 70s valleys. An upper level system with a
cold front will move through eastern Idaho Wednesday night and
expect much colder conditions Thursday through Saturday with
periods of rain and snow. Snow levels expected to drop all the way
down to 5 to 6 thousand feet at the end of the week. High
temperatures in the period generally expected to be in the 40s
mountains and 50s valleys. Expect windy conditions as well with
