Fire Weather Planning Forecast for Northeast Montana

206 PM MDT Sun Sep 29 2024

...RED FLAG WARNING IN EFFECT UNTIL 7 PM MDT MONDAY
FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY...

.DISCUSSION...
Periods of widespread critical fire weather conditions are likely
through late tonight. The primary concern this afternoon will
be record temperatures as high as the upper 90s along with
humidity as low as 10 percent. Most locations have high
to very high fire danger with further curing of fuels occurring
today. The hot/dry/windy index today is well above the 95th
percentile or at record highs for this time of year. Winds will be
mostly in the 10 to 25 mph range this afternoon, before
increasing into the 20 to 35 mph range with gusts up to 55 mph
behind a cold frontal passage this evening. This frontal passage
brings almost zero chance of any wetting rain, while coming with
enough cloud cover and drier air to limit humidity recovery until
after midnight.

Near critical conditions will linger into Monday afternoon,
particularly outside of the Little Rockies where the gusty winds
that begin this evening remain more persistent. Despite the notably
stronger winds compared to the previous afternoon, humidity will be
slightly higher Monday at around 20 percent along with much
cooler temperatures. Looking ahead, Tuesday afternoon will also
have slightly elevated fire weather conditions due to lower
humidity and potential for gusty winds to a lesser extent.
