122 AM MDT SAT MAY 9 2026
KEY MESSAGES

THUNDERSTORMS.
- ABOVE NORMAL TEMPERATURES AND DRIER CONDITIONS SUNDAY INTO MID
WEEK.
- WIDESPREAD WIND GUSTS OF 25 TO 35 MPH POSSIBLE MONDAY.
DISCUSSION
TODAY THROUGH FRIDAY...
A SHORTWAVE TROUGH MOVING THROUGH WILL CONTINUE TO BRING
SCATTERED SHOWERS THIS MORNING. ENERGY BEING ADVECTED INTO THE
REGION BEHIND THE MAIN TROUGHING WILL ALLOW SCATTERED WEAK
THUNDERSTORMS TO DEVELOP BY THIS AFTERNOON. THE HIGHEST CAPE
VALUES REMAIN LESS THAN 500 J/KG AND 0-6 KM SHEAR IS ONLY 10-20
KTS, SO ANY HAIL WILL REMAIN SMALL. THE BEST CHANCE (50-80%) FOR
SHOWERS AND THUNDERSTORMS TODAY REMAINS FROM BILLINGS EAST.
UPPER LEVEL RIDGING RETURNS FOR SUNDAY THROUGH MIDWEEK, BRINGING
WARM AND MOSTLY DRY CONDITIONS. HIGHS WILL INCREASE FROM LOW 70S
TO LOW 80S SUNDAY TO 80S TO NEAR 90 BY WEDNESDAY.
A DISTURBANCE MOVING ACROSS NORTHERN MONTANA LATE SUNDAY INTO
MONDAY WILL BRING WIDESPREAD GUSTS OUT OF THE NORTH OF 25 TO 40
MPH TO THE REGION, BUT NO PRECIPITATION IS EXPECTED. GIVEN THE
ABOVE NORMAL TEMPERATURES, ANY AREAS THAT HAVE NOT RECENTLY
RECEIVED PRECIP WILL BE AT A GREATER RISK FOR GRASS FIRES TO
SPREAD MONDAY. TAKE CARE NOT TO CAUSE A SPARK!
LATE WEEK, THERE ARE SIGNS OF THE PATTERN BECOMING UNSETTLED. THE
TIMING AND IMPACTS ARE STILL VERY UNCERTAIN, BUT THERE IS MODERATE
CONFIDENCE FOR DAILY PRECIP CHANCES TO RETURN BY THE END OF THE
WORK WEEK. ARCHER
AVIATION
VFR CONDITIONS WILL PREVAIL THROUGH THE DAY. HOWEVER, THERE WILL
BE AN INCREASE IN SHOWER COVERAGE (SCATTERED TO NUMEROUS)
INCLUDING A LARGE BAND OF PRECIPITATION DEVELOPING, AND EXTENDING
NW TO SE FROM THE FRONT RANGE OF MONTANA TO THE BIG HORNS REGION
IN NORTH CENTRAL WYOMING. ISOLATED TO WIDELY SCATTERED
THUNDERSTORMS ARE POSSIBLE IN THIS AREA AS WELL, ESPECIALLY
BETWEEN 16Z AND 01Z WITH IMPACTS MOSTLY LIKELY AT KSHR AND KBIL.
LOCAL MVFR CONDITIONS CAN BE EXPECTED NEAR SHOWER ACTIVITY ALONG
WITH WIND GUSTS 25-30 KTS. MTN TOPS MAY BE OBSCURED AT TIMES.
THUNDER/SHOWER ACTIVITY DROPS OFF SIGNIFICANTLY AFTER 01Z SUNDAY.
