WEEKEND.
- UNSETTLED CONDITIONS SUNDAY INTO MONDAY WILL KEEP SEASONABLE

DISCUSSION
TODAY THROUGH WEDNESDAY...
BROAD RIDGING WILL KEEP THE REGION WARM AND MOSTLY DRY THROUGH
SATURDAY. AS SPLITTING ENERGY MOVES TO THE NORTH AND SOUTH OF THE
REGION, A DRY COLD FRONTAL PASSAGE IS EXPECTED TO MOVE THROUGH
FRIDAY EVENING. AHEAD OF THIS FRONT, CONDITIONS ARE EXPECTED TO
BE BREEZY AHEAD OF AND WITH THE FRONTAL PASSAGE WITH GUSTS 25-35
MPH EXPECTED ACROSS SOUTHEAST MT. HI- RES MODELS GENERALLY HAVE
ISOLATED LIGHT SHOWERS FOR PORTIONS OF SOUTH CENTRAL AND SOUTHEAST
MT FRIDAY EVENING. WITH A LITTLE INSTABILITY ACROSS SOUTHEAST MT,
AN ISOLATED THUNDERSTORM OR TWO IS POSSIBLE FRIDAY EVENING. THIS
WILL ALSO COOL TEMPERATURES FROM THE UPPER 70S AND LOW 80S (TODAY
AND FRIDAY) TO THE 60S AND LOW 70S THIS WEEKEND THROUGH MID WEEK.
ENSEMBLES THEN DEPICT AN ADDITIONAL SYSTEM WORKING INTO THE AREA
LATE SUNDAY INTO MONDAY, BUT THE BETTER FORCING LOOKS TO TRACK
SOUTH. WEAK FORCING IS CURRENTLY PRODUCING SOME SHOWERS ACROSS THE
REGION. CURRENTLY, THERE IS ABOUT A 25-50% CHANCE FOR AT LEAST A
QUARTER INCH OF PRECIPITATION SUNDAY-MONDAY WITH ABOUT A 50-70%
CHANCE FOR AREA MOUNTAINS. WITH THIS, THERE IS ABOUT A 20-40%
CHANCE FOR AT LEAST 2 INCHES OF SNOW, GENERALLY ABOVE 8500 FT
(INCLUDING THE BEARTOOTH PASS) MONDAY NIGHT INTO TUESDAY MORNING.

NORTH-EASTERN WYOMING, INCLUDING KMLS, KBHK, AND POSSIBLY KSHR.

ADVECTING INTO FAR EASTERN MONTANA REMAINS LOW. LATE FRIDAY,
WINDS WILL BEGIN TO INCREASE OVER SOUTH-CENTRAL MONTANA AHEAD OF
