URGENT - FIRE WEATHER MESSAGE
National Weather Service Twin Cities/Chanhassen MN
330 AM CDT Mon Sep 30 2024

...CRITICAL FIRE WEATHER CONDITIONS ACROSS PORTIONS OF WESTERN 
AND CENTRAL MINNESOTA MONDAY...

.Monday will see a dry cold front sweeping west to east across
the region, reaching western Minnesota by the early afternoon
both increasing winds and significantly lowering dewpoints. 
Minimum humidity values could reach the teens in spots, with low 
to mid 20s across a large portion of western to central Minnesota.
Dewpoints are expected to drop from near 50 ahead of the front to
the low to mid 30s behind the front. Meanwhile, highs will reach 
the upper 70s to near 80. Winds will increase out of the northwest
behind the front with gusts of 25-30 mph possible, mainly during 
the late afternoon to evening in western Minnesota. Winds are 
generally expected to be weaker east of a line stretching from St.
Cloud to Mankato due to the timing of the front, with a later 
arrival time allowing for a gap between the lowest humidity and 
strongest winds arriving after sunset. The Red Flag Warning covers
the area most likely to have ideal timing of the frontal passage,
allowing for the strongest winds to sync up with the lowest humidity.
