SHORT TERM
Today and Saturday.
Looking at current radar and satellite imagery, there continues to be light to moderate snow from mainly I-15 to the Wyoming line with an exiting system. High pressure is building in from the west. Have left out the winter weather advisory along our eastern areas until 5 pm where 1 to 3 inches of additional snow is possible. Have canceled the winter weather advisories for the Lower Snake plain, Raft River, and the Southern Hills/Albion Mtns.
Have also canceled the wind advisory over the Lower Snake Plain and the Marsh/Albion Highlands. Have kept the wind advisory for the Eastern Magic valley, Raft River, and the Southern Hills/Albion mountains until 5 pm, as winds continue to be elevated with high pressure building in. Have kept the Winter Storm Warning for the Wasatch mountains going until 9 pm with up to 6 inches of more snow likely.

Expect high pressure to continue to build in overnight. Look for patchy freezing fog tomorrow, Saturday, morning. Expect mostly clear skies early on Saturday as well as overall dry conditions with cooler than normal temperatures. The leading edge of the overrunning snowfall with the next approaching system spreads into the western Central mountains Saturday night. See discussion below for more on the next system that comes in late Saturday through Monday.

LONG TERM
Sunday through Friday.
Main impact will be extensive Pacific moisture overriding upper ridge into southeast Idaho. Will likely have light snow Sunday through Monday night. Initial 48 hour 50 percent snow amounts are not overly impressive with generally 2 to 4 inches in the central and eastern mountains with locally higher amounts over passes. and a half inch to 2 inches in the Snake River Plain. Tuesday through Friday in the model blends are dry with only isolated mountain snow showers expected but no significant accumulations. There are some difference in the operational long term models toward the end of the extended with the European model with a closed upper low on Friday possibly producing snow but very minimal confidence in that solution if any that far out. For now have the dry conditions with slightly above normal temperatures Tuesday through Friday. Highs predominately in the 30s with lows in the teens and 20s with some single digits in normal cold locations such as Stanley in the entirety of the long term period.
