KEY MESSAGES
- TEMPERATURES WILL STEADILY CLIMB THROUGH THE WEEKEND, WITH
MANY AFTERNOON HIGHS REACHING THE 40S AND LOWER 50S BY SUNDAY.
- LIGHT SNOW IS EXPECTED IN PORTIONS OF THE CENTRAL MOUNTAINS
AND ISLAND PARK REGIONS THROUGH TONIGHT, THOUGH ACCUMULATIONS
WILL REMAIN UNDER 2 INCHES.

WARMING TREND RETURNS THROUGH THE END OF THE WEEK.
SHORT TERM /THROUGH TONIGHT/
ISSUED AT 130 AM MST FRI JAN 30 2026
EARLY MORNING SATELLITE SHOWS AREAS OF STRATUS, YET NOT AS
WIDESPREAD AS 24 HOURS PRIOR AS MID- TO HIGH-LEVEL CLOUDS ARE
INHIBITING EXPANSION OF STRATUS AND FOG DEVELOPMENT. WHILE THE
MAJORITY OF SOUTHEAST IDAHO WILL REMAIN DRY TODAY, WEAK MOISTURE
WILL FILTER INTO OUR NORTHEASTERN MOUNTAINS IN NORTHWEST FLOW, WHERE
UP TO AN INCH OR SO OF SNOW WILL ACCUMULATE THIS AFTERNOON AND
EVENING. GRADUAL WARMING IS EXPECTED TO CONTINUE AS HIGH PRESSURE
DOMINATES THE UPPER-LEVEL PATTERN, ALTHOUGH CLOUD COVER COULD
INHIBIT DAYTIME HEATING.
LONG TERM /SATURDAY THROUGH THURSDAY/
ISSUED AT 113 PM MST THU JAN 29 2026
UPPER RIDGE AXIS TRANSITIONS INTO EAST IDAHO FOR THE WEEKEND,
LEADING TO WARMING TREND ACROSS THE REGION. THIS MAY COME WITH
THE CAVEAT OF RENEWED POTENTIAL FOR LOW ELEVATION STRATUS AND
FOG, WHICH MAY THEN DAMPEN TEMPERATURES SLIGHTLY. THE NBM MEANS
STILL CARRY HIGHS IN THE MID 40S TO LOW 50S BY SUNDAY FOR MOST
LOWER ELEVATION AREAS. ANOTHER WEAK FEATURE TRIES TO TOP THE
RIDGE LATE SUNDAY THROUGH MONDAY, WITH ANOTHER CHANCE FOR LIGHT
SNOW ACROSS HIGHER ELEVATION AREAS. ONCE AGAIN, THE CHANCE FOR
MORE THAN AN INCH OR TWO OF ACCUMULATION AT HIGHER ELEVATIONS IS
MINIMAL. THE UPPER RIDGE AXIS STRENGTHENS ONCE AGAIN BEHIND THIS
FEATURE, WITH CONTINUED WARMING THROUGH MIDWEEK. THE AREA
COVERED BY A GREATER THAN 50% PROBABILITY OF TEMPERATURES
EXCEEDING 50 DEGREES GROWS SIGNIFICANTLY BY THURSDAY, COVERING A
BROAD SWATH SOUTH OF A LINE FROM SHOSHONE TO BLACKFOOT.
