DISCUSSION
/ISSUED 611 PM MST MON FEB 2 2026/
- METEOROLOGICAL OVERVIEW:
ANOMALOUSLY STRONG UPPER LEVEL RIDGING IS DEVELOPING ACROSS THE
REGION THIS AFTERNOON. BEFORE THE RIDGING FULLY MOVES IN A WEAK
DISTURBANCE SLIDING SOUTHEASTWARD WITHIN THE NORTHWESTERLY FLOW
ALOFT WILL RESULT IN SOME LIGHT MAINLY MOUNTAIN PRECIPITATION
TONIGHT.
PROBABILITY FOR PRECIPITATION QUICKLY WANES THROUGH THE MORNING
TUESDAY AS UPPER LEVEL RIDGING BECOMES FULLY ENTRENCHED.
TEMPERATURES WILL BEGIN TO TREND WARMER AS A RESULT ACROSS THE
REGION, PEAKING IN THE WEDNESDAY THROUGH FRIDAY TIMEFRAME AS THE
RIDGE PEAKS IN INTENSITY. WINDS WILL BE BREEZY AT TIMES THROUGH
THE WEEK, BUT ARE NOT LOOKING IMPACTFUL.
HEADING INTO THE WEEKEND THE RIDGE BEGINS TO WEAKEN, THOUGH AT
LEAST INITIALLY THIS REALLY ONLY RESULTS IN TEMPERATURES COOLING
SLIGHTLY, WITH ANOTHER ROUND OF BREEZY WINDS ON SATURDAY. GREATER
UNCERTAINTY BUILDS HEADING INTO SUNDAY AND MONDAY, WITH SOME
ENSEMBLE MEMBERS BRINGING LIGHT PRECIPITATION INTO THE REGION. THE
MAIN TAKEAWAY AT THIS POINT IS THERE IS NO CLEAR SIGNAL FOR A
LARGE PATTERN SHIFT AT THIS TIME TOWARD ANYTHING SIGNIFICANTLY
COLDER/WETTER EARLY NEXT WEEK.
- FORECAST CONFIDENCE & SCENARIOS:
TEMPERATURES: THE ONLY QUESTIONS FOR TEMPERATURES WEDNESDAY
THROUGH FRIDAY IS JUST HOW WARM THEY GET. MOST DAYS LOOK TO LACK
SIGNIFICANT CLOUD COVER, BUT EVEN A LITTLE WOULD HINDER
TEMPERATURES A BIT. FOR NOW WE HAVE LEANED TOWARD THE WARMER SIDE
OF THE ENVELOPE FOR FORECAST HIGHS.
THIS WEEKEND INTO EARLY NEXT WEEK:
ENSEMBLE AVERAGES SHIFT THE RIDGE EASTWARD THIS WEEKEND, LEAVING
A SOUTHWESTERLY FLOW ALOFT. ALTHOUGH THIS IS THE CASE, THERE IS
NOT SUPPORT FOR ANY STRONG SYSTEMS TO MOVE IN BEHIND THE RIDGE.
HENCE, THE TREND INTO EARLY NEXT WEEK WILL BE FOR TEMPERATURES TO
TREND CLOSER TO AVERAGE, WITH LOW PROBABILITIES FOR PRECIPITATION
SNEAKING BACK INTO THE FORECAST. -AM
AVIATION
03/06Z TAF PERIOD
LOW-VFR/VFR CONDITIONS WILL PREDOMINATELY PERSIST ACROSS SOUTHWEST
THROUGH NORTH CENTRAL MONTANA OVER THE NEXT 24 HOURS; HOWEVER,
TEMPORARY MVFR CONDITIONS MAINLY DUE TO LOW CIGS COULD IMPACT THE
KBZN, KEKS, AND KLWT TERMINALS THROUGH 12-15Z TUESDAY.
ADDITIONALLY, AN ISOLATED RAIN/SNOW SHOWER CAN'T BE RULED OUT AT
THE KLWT TERMINAL OVER THIS TIMEFRAME, BUT THE PROBABILITY OF THIS
OCCURRING IS ONLY AROUND A 30% CHANCE. MOUNTAINS WILL REMAIN
OBSCURED THROUGH 18Z TUESDAY. - MOLDAN
FIRE WEATHER
EARLY SEASON MILD TEMPERATURES ARE EXPECTED FROM WEDNESDAY THROUGH
FRIDAY OF THIS WEEK. IT WILL BE BREEZY DURING THE AFTERNOON HOURS,

AREAS. BRUSDA
