SPOT FORECAST FOR BENCHMARK 1A 1B...USFS
NATIONAL WEATHER SERVICE GREAT FALLS MT
354 PM MST WED FEB 4 2026
FORECAST IS BASED ON IGNITION TIME OF 1600 MST ON FEBRUARY 04.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
UNUSUALLY WARM TEMPERATURES FOR EARLY FEBRUARY ARE EXPECTED THE
NEXT FEW DAYS AS A STRONG UPPER LEVEL RIDGE LINGERS OVER THE AREA.
EVEN WITH THIS RIDGE OVERHEAD, EXPECT DECENT RH RECOVERIES
OVERNIGHT, WITH MOST AREAS RISING TO AROUND 60% OR SO, THOUGH
THERE IS A CHANCE MID SLOPE LOCATIONS RECOVER MORE POORLY TONIGHT.
TOMORROW WILL BRING VERY WARM TEMPERATURES WITH RISING TO THE MID
50S EVEN IN THE MID AND UPPER SLOPES. MIXING HEIGHT FORECASTS ARE
TRICKY, AS WARM AIR SHOULD BE FOUND IN A LAYER AT AND JUST ABOVE
THE BURN ELEVATION KEEPING MIXING HEIGHTS TO AROUND 500FT, BUT
SHOULD THIS WARM LAYER MIX OUT MIXING HEIGHTS WOULD RISE SUDDENLY
TO AROUND 10,000 FEET ABOVE THE GROUND. AS OF NOW, THE ATMOSPHERE
SHOULD REMAIN CAPPED AND KEEP THE MIXING HEIGHTS LOW, WITH AROUND
A 20% CHANCE OF THE HIGHER MIXING HEIGHTS DURING THE AFTERNOON.
