DISCUSSION
ISSUED AT 119 PM MDT SAT MAR 28 2026
SATELLITE IMAGERY SHOWS FLAT RIDGE OVER EAST IDAHO WITH
UPSTREAM DEEP TROUGH IN THE GULF OF ALASKA. VERY WARM
TEMPERATURES REMAIN ON TAP INTO SUNDAY AS UPPER LOW APPROACHES
THE COAST. SHOULD SEE AN INCREASE IN UPPER LEVEL CLOUD COVER
ALONG WITH WINDS INCREASING SUNDAY AFTERNOON ACROSS THE REGION.
HELD WIND FORECAST GRIDS JUST SHY OF WIND ADVISORY, BUT IT WILL
BE CLOSE ACROSS THE ARCO DESERT AND UPPER SNAKE PLAIN ZONES. NBM
PROBABILITIES SUPPORT A GREATER THAN 60% CHANCE OF GUSTS
EXCEEDING 45 MPH ACROSS THESE AREAS. WINDS WILL BE STRONGER ON
MONDAY AS THE COLD FRONT SHIFTS THROUGH THE REGION. MAX
SUSTAINED WINDS LOOK TO APPROACH OR EXCEED 40 MPH ACROSS THE
ARCO DESERT AND UPPER SNAKE PLAIN, INCLUDING THE SH-33 AND US-26
REGIONS EAST OF IDAHO FALLS. FOR THESE AREAS ON MONDAY, THERE
IS A 45-70% CHANCE OF GUSTS EXCEEDING 50 MPH. WHILE LOCALIZED
BLOWING DUST WILL BE POSSIBLE SUNDAY AFTERNOON, EXPECTATIONS
WOULD BE HIGHER FOR MONDAY, AND UNLESS GUIDANCE SIGNIFICANTLY
DECREASES, MONDAY WOULD BE THE MORE OBVIOUS DAY FOR A WIND
ADVISORY.
SHOWERS ALSO ACCOMPANY THE FRONT MONDAY, BUT MAINLY OVER HIGHER
ELEVATIONS AND REMAINING LIGHT. WOULD ALSO NOT BE SURPRISED TO
SEE AN ISOLATED THUNDERSTORM DEVELOP ACROSS THE NORTHEAST CORNER
OF THE FORECAST AREA, AS TIMING OF THE FRONT AND SHOWERS WOULD
COINCIDE WITH STRONGEST HEATING. SNOW LEVELS REMAIN HIGH SO
LIGHT ACCUMULATIONS LESS THAN 2" REMAIN LIMITED TO AREAS AROUND
PASS LEVEL. BY THE TIME COOLER TEMPERATURES ARRIVE BEHIND THE
FRONT, THE PRECIPITATION WILL HAVE SHIFTED SOUTHEAST. FRONT
LIFTS BACK NORTH TUESDAY, WITH PRECIPITATION MAINLY ACROSS THE
SOUTHERN HIGHLANDS.
UPPER LOW FINALLY SHIFTS INLAND WEDNESDAY NIGHT, WITH
PRECIPITATION BECOMING MORE WIDESPREAD ACROSS THE REGION
WEDNESDAY THROUGH THURSDAY. TEMPERATURES LOOK TO COOL FOR
THURSDAY AND FRIDAY BACK TO SEASONAL NORMALS. THIS COULD MEAN
SNOW LEVELS LOWER TO VALLEY FLOORS AT NIGHT, AND ACCUMULATIONS
WILL BE HIGHLY DEPENDENT ON TIMING OF PRECIPITATION WAVES WITH
THE COOLEST TEMPERATURES. A RIDGE OF HIGH PRESSURE DOES LOOK TO
BE ON TAP FOR NEXT WEEKEND AS THE LOW SHIFTS EAST FRIDAY,
LEADING TO DRIER NORTHWEST FLOW FOR EAST IDAHO.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

AFTERNOON SUNDAY. GUSTS OF 15-25KTS ARE POSSIBLE TODAY,
INCLUDING SUN (CLOSER TO 15-20KTS THERE). TOMORROW, THEY WILL BE
20-35KTS GENERALLY, STRONGEST AT PIH AND IDA.
