FIRE WEATHER PLANNING FORECAST FOR SCEN AND SERN MONTANA
NATIONAL WEATHER SERVICE BILLINGS MT
1259 AM MDT SUN JUN 28 2026
DISCUSSION
SLOW MOVING STORM SYSTEM WILL BE IN THE AREA OVER THE NEXT FEW
DAYS. CORE OF THE SYSTEM WILL BE NORTH OF THE FIRE DISTRICT, WHICH
WILL BRING DRIER AND WINDY CONDITIONS TO MOST OF THE AREA, THOUGH
THERE WILL BE PERIODS OF SHOWERS AND THUNDERSTORMS IN THE
FORECAST. THE BEST CHANCE FOR WETTING RAINS SUNDAY AND MONDAY WILL
BE OVER THE WESTERN MOUNTAIN AND FOOTHILLS ZONES (60-90%),
DECREASING TO 40% CENTRAL AND 20% EAST. EXPECT ACCUMULATING
MOUNTAIN SNOW ABOVE 8000 FEET WITH 2 TO 4 INCHES COMMON, AND
HIGHER VALUES UP TO 10 INCHES POSSIBLE ON HIGHER NORTHWEST FACING
SLOPES.
WESTERLY WINDS WILL INCREASE TODAY (GUSTS 25 TO 40 MPH)
AND TOMORROW (GUSTS 30 TO 50 MPH) WITH THE STRONGEST GUSTS FROM
BILLINGS WEST INTO THE FOOTHILLS. DESPITE THE DOWNSLOPE WESTERLY
WINDS, AFTERNOON RH VALUES WILL REMAIN ELEVATED (30-60%) AND
AFTERNOON TEMPERATURES WILL RANGE FROM THE 60S WEST TO THE
LOWER/MID 70S EAST THROUGH MONDAY.
A RETURN TO A MORE TYPICAL SUMMER TIME WEATHER PATTERN ARRIVES
TUESDAY AND STICKS THROUGH THE REST OF THE WEEK. TEMPERATURES WILL
CLIMB INTO THE 80S BY WEDNESDAY WITH LOWER 90S POSSIBLE THU/FRI.
THERE WILL BE CHANCES FOR MAINLY AFTERNOON/EVENING SHOWERS AND
THUNDERSTORMS EACH DAY BUT WETTING RAIN CHANCES WILL BE LOW DURING
THIS PERIOD. CHAMBERS
