DISCUSSION

SATELLITE IMAGERY THIS AFTERNOON SHOWS WIDESPREAD CLOUD COVER
ACROSS EASTERN IDAHO AS A WEAK WEATHER DISTURBANCE MOVES QUICKLY
THROUGH THE REGION. DESPITE THE CLOUDS AND ONGOING LIGHT
PRECIPITATION, TEMPERATURES REMAIN NEAR SEASONAL AVERAGES, WITH
VALLEY HIGHS IN THE 40S. HIGH-RESOLUTION WEATHER MODELS INDICATE
THAT RAIN AND SNOW SHOWERS WILL TAPER OFF TONIGHT AS THE
DISTURBANCE MOVES EAST INTO WYOMING. EXPECT PARTIAL CLEARING
FROM WEST TO EAST OVERNIGHT, THOUGH SOME LOW-LEVEL CLOUDS MAY
LINGER IN THE SNAKE PLAIN AND MAGIC VALLEY THROUGH EARLY TUESDAY
MORNING. TUESDAY LOOKS RELATIVELY QUIET AS A BRIEF PERIOD OF
HIGH PRESSURE BUILDS OVER THE AREA.
A "SPRING-LIKE" PATTERN TAKES HOLD MID-WEEK AS A PACIFIC SYSTEM
BEGINS DIGGING INTO THE REGION. WEDNESDAY WILL BE QUITE MILD,
WITH VALLEY TEMPERATURES REACHING THE MID TO UPPER 50S. WHILE
MOISTURE IS SOMEWHAT LIMITED, PRECIPITATION WILL INCREASE BY
WEDNESDAY AFTERNOON. SNOW IS EXPECTED FOR THE HIGHER TERRAIN OF
THE CENTRAL MOUNTAINS AND EASTERN HIGHLANDS, GENERALLY STAYING
ABOVE 6,000 FEET. THIS SYSTEM SHIFTS OVERHEAD ON THURSDAY,
USHERING IN COOLER AIR AND DROPPING VALLEY HIGHS BACK INTO THE
40S FOR THE REMAINDER OF THE WEEK. SHOWERY PRECIPITATION WILL
LINGER INTO FRIDAY, PRIMARILY CONFINED TO THE MOUNTAINS. THERE
IS SOME UNCERTAINTY IN THE MODELS REGARDING WHETHER THIS SYSTEM
CUTS OFF FROM THE MAIN ATMOSPHERIC FLOW, WHICH COULD IMPACT HOW
LONG SHOWERS STICK AROUND LATE IN THE WEEK.
CONDITIONS LOOK TO TREND QUIETER BY THE WEEKEND AS PRESSURE
ALOFT INCREASES. THIS WILL ALLOW TEMPERATURES TO RETURN TO THE
50S FOR VALLEY LOCATIONS, WITH ANY REMAINING RAIN OR SNOW
SHOWERS LIMITED TO THE HIGH COUNTRY. LOOKING TOWARD EARLY NEXT
WEEK, WEATHER MODELS ARE SHOWING INCREASING AGREEMENT THAT A
BROADER PACIFIC SYSTEM WILL APPROACH THE INTERMOUNTAIN WEST BY
MONDAY. WHILE SPECIFIC DETAILS REGARDING TIMING AND TOTALS ARE
STILL BEING FINALIZED, PRECIPITATION CHANCES ARE EXPECTED TO
RISE ONCE AGAIN. OVERALL, EXPECT THE ACTIVE SPRING PATTERN TO
PERSIST WITH NO SIGNIFICANT ARCTIC AIR INTRUSIONS ON THE
HORIZON.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1054 AM MST MON MAR 2 2026
SHOWERS CONTINUE ACROSS EASTERN IDAHO ESPECIALLY CLOSER TO I-15
AND POINTS EAST. WE ARE SEEING A MIX OF MVFR/IFR CONDITIONS DUE
TO SHOWERS AND EVEN POCKETS OF FOG WHERE PRECIPITATION HAS ENDED
OR SUBSTANTIALLY DROPPED OFF THIS AFTERNOON. THE STORM
RESPONSIBLE FOR ALL OF THIS WILL BE OFF TO OUR EAST IN THE NEXT
24 HOURS. ONCE WE SEE AN END TO ANY RISK OF SHOWERS, WE ARE
LOOKING AT THE POTENTIAL FOR MVFR/IFR WEATHER TO DUE TO LOW
CEILINGS AND/OR POCKETS OF FOG TONIGHT AND TOMORROW MORNING. WE
HAVE INCLUDED THAT IN ALL TAFS EXCEPT FOR SUN, WHICH SHOULD
EVENTUALLY GO VFR AND STAY THERE.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
