SHORT TERM /THROUGH TUESDAY NIGHT/
Issued at 1241 PM MDT Mon May 12 2025
Upper level trof continues to push east and will spread showers back into southeast Idaho tonight through Tuesday night. Snow levels will drop to 6 to 7 thousand feet overnight. Any accumulations will be well over 7 thousand feet with snow levels rising Tuesday to over 7 thousand feet once again. Lows tonight in the 20s and 30s mountains and 40s valleys. Highs Tuesday will be significantly colder with 40s to low 50s mountains and 50s valleys. Lows Tuesday night will be in the 20s and 30s mountains and 30s to lower 40s valleys. Will see thunderstorms Tuesday afternoon but only expecting isolated mainly mountain coverage but can't be ruled out anywhere. Instability will be limited by significantly colder temperatures but enough to not rule out the thunderstorm activity. Expect 10 to 20 mph west to southwest winds through Tuesday in the Snake River Plain.
LONG TERM /WEDNESDAY THROUGH MONDAY/
Issued at 1241 PM MDT Mon May 12 2025
The weather in the coming days will remain more on the cool and wet side of the spectrum. Another slow moving low will keep some lighter rain and mountain snow showers in place through Thursday. the bulk of the moisture will fall outside of the central mountains, Magic Valley and South Hills/Albion Mountains. There's a 40-70% chance of more than 0.50" of moisture over the Big Holes/Tetons/Island Park through Thursday night. We get a bit of break later Friday before another split flow storm creeps across the western states, at least that is what the latest GFS and ECMWF think will happen. If you look at the cluster forecasts, that only follows about what 30% of that is depicting. The rest show a rather progressive/fast moving system. Our Blend of Models seems to follow along with the slow mover scenario through the weekend and into next week. The "warmest" day will be Saturday where we will be fairly close to average. Otherwise, highs will be pushing 5-10 degrees BELOW average other days.
AVIATION /00Z TAFS THROUGH 00Z TUESDAY/
