DISCUSSION

- METEOROLOGICAL OVERVIEW:
WITH AN UPPER LEVEL RIDGE OF HIGH PRESSURE MOVING EASTWARD OVER MT
OVER THE NEXT FEW DAYS, EXPECT DRIER AND MILDER AIR TO MOVE INTO
THE CWA. ADDITIONALLY, STRONG WINDS ARE EXPECTED OVER NORTH
CENTRAL MT AT TIMES STARTING TODAY, AND THEN CONTINUING INTO
MONDAY. THERE IS SOME POTENTIAL THE STRONG WINDS COULD CONTINUE IN
THE CUT BANK AREA INTO MID WEEK. THE ONLY CHANGE TO THE HIGH WIND
STATEMENT WAS TO START THE STRONG WINDS TODAY IN THE CUT BANK AREA
THIS MORNING. OTHERWISE, THE REST OF THE HIGH WIND STATEMENT IS ON
TRACK.
AFTERNOON TEMPERATURES WILL BE NEAR RECORD HIGHS FOR THE FIRST
HALF OF THE WEEK.
THERE IS THE POTENTIAL FOR THE FLOW ALOFT TO SHIFT A BIT NORTHERLY
COME THURSDAY. THIS WOULD ALLOW FOR SLIGHTLY COOLER AIR TO MOVE
BACK INTO THE CWA FOR A FEW DAYS, BUT OVERALL TEMPERATURES WILL
STILL BE ABOVE NORMAL.
IN TERMS OF PRECIPITATION, THERE IS A SMALL CHANCE FOR A PASSING
MOUNTAIN SHOWER MONDAY INTO TUESDAY, BUT THE PROBABILITY OF A
SHOWER IS LOW AND ANY PRECIPITATION THAT DOES FALL WILL BE LIGHT.
FOR THURSDAY, BOTH THE EC AND GFS CONTINUE TO HAVE SEPARATE
SOLUTIONS, WITH THE EC DRY AND THE GFS HAVING SOME SCATTERED
SHOWERS. THE NBM IS MOSTLY DRY, AND THAT IS THE PREFERRED SOLUTION
AT THIS TIME. BY NEXT WEEKEND, AFTERNOON TEMPERATURES COULD ONCE
AGAIN BE CLOSE TO 15 DEGREES ABOVE NORMAL.
- FORECAST CONFIDENCE & SCENARIOS:
THERE IS AN 80 PERCENT CHANCE FOR HIGH WINDS TODAY IN THE CUT BANK
AREA, THUS THE HIGH WIND WARNING WAS ADDED FOR TODAY.
OTHERWISE, THERE IS A 90 PERCENT CHANCE FOR HIGH WINDS ON MONDAY
ACROSS MUCH OF NORTH CENTRAL MT. BLOWING DUST COULD BE AN IMPACT
OVER THE PLAINS AT TIMES.
THERE IS AN 80 PERCENT CHANCE OF RECORD HIGH TEMPERATURES ACROSS
PORTIONS OF NORTH CENTRAL MT ON TUE AND THAT PROBABILITY INCREASES
TO ABOVE 90 PERCENT FOR WEDNESDAY. BRUSDA
AVIATION
11/18Z TAF PERIOD
VFR CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THE AFTERNOON AND
INTO THE OVERNIGHT HOURS EVEN AS WINDS INCREASE AND MID/UPPER
LEVEL CLOUDS CONTINUE TO PASS OVER THE AREA. WINDS INCREASE FURTHER
TOMORROW, BRINGING AREAS OF LLWS AND BLDU TO THE AREA, WHICH COULD
RESULT IN LOCALIZED MVFR TO IFR CONDITIONS AND TURBULENCE ON
ASCENT/DESCENT. LUDWIG
FIRE WEATHER
LOW HUMIDITY, GUSTY WINDS, AND MILD AFTERNOON TEMPERATURES ARE
EXPECTED THE NEXT FEW DAYS. THIS WILL ELEVATE FIRE CONDITIONS OVER
GRASSY AREAS THE NEXT FEW DAYS. OVERALL, OBSERVED HUMIDITY HAS
BEEN QUITE A BIT LOWER THAN FORECAST, WITH SOME AREAS CLOSE TO 10
PERCENT ON SATURDAY. THUS, AFTERNOON HUMIDITY IN THE TEENS IS
LOOKING LIKELY OVER THE PLAINS THE NEXT FEW DAYS. VERY POOR
RECOVER IS OCCURRING AT NIGHT, WITH MANY AREAS STAYING IN THE LOW
20 PERCENT RANGE. THE COMBINATION OF GUSTY WINDS AND LOW HUMIDITY
WILL MAKE CONTAINING ANY NEW FIRE STARTS IN GRASSY AREAS A BIT
MORE DIFFICULT THROUGH MID WEEK. BRUSDA
