FIRE WEATHER PLANNING FORECAST FOR SCEN AND SERN MONTANA
NATIONAL WEATHER SERVICE BILLINGS MT
338 AM MST MON NOV 24 2025
DISCUSSION
A COLD FRONT WILL CROSS OVER ALL DISTRICTS LATE THIS MORNING
THROUGH THE AFTERNOON, SHIFTING WINDS TO THE WEST TO NORTHWEST AND
BRINGING A LINE OF RAIN/SNOW SHOWERS WITH IT. THERE IS ALSO A
SMALL CHANCE FOR THUNDERSTORMS TO OCCUR WITH THE FRONTAL PASSAGE.
WINDS DURING AND BEHIND THE FRONT WILL GUST 25 TO 55 MPH, WITH
HIGHER GUSTS OCCURRING WEST OF BILLINGS AROUND HARLOWTON AND BIG
TIMBER, AND ACROSS FAR SOUTHEAST MT.
BEHIND THE FRONT BRINGS ABOUT THE FIRST ELONGATED SHOT OF COOLER
AND WETTER CONDITIONS WE'VE SEEN ALL FALL. THE SECOND HALF OF THE
WEEK WILL SEE LIGHT PRECIPITATION (LIKELY ALL SNOW) OCCURRING
EACH DAY, WITH A POTENTIALLY LARGER SYSTEM SWINGING THROUGH OVER
THE WEEKEND DROPPING TEMPERATURES EVEN MORE. STILL MUCH
UNCERTAINTY WITH THE WEEKEND SYSTEM, BUT CONFIDENCE IS HIGH FOR
CONDITIONS TO REMAIN COOLER AND WETTER FOR THIS WEEKEND. VERTZ
