FIRE WEATHER PLANNING FORECAST FOR SOUTHEAST WYOMING/WESTERN NEBRASKA
NATIONAL WEATHER SERVICE CHEYENNE WY
403 AM MST WED DEC 17 2025
...ELEVATED FIRE WEATHER CONCERNS ONGOING THROUGH FRIDAY PRIMARILY
ACROSS THE HIGH PLAINS OF THE REGION...
...HIGH WIND WARNINGS IN EFFECT THROUGH 11 AM MST THURSDAY FOR
MOST OF SOUTHEAST WYOMING AND THE NEBRASKA PANHANDLE...
DISCUSSION
WINDS BEGIN TO INCREASE THIS MORNING AND WILL
CONTINUE TO REMAIN ELEVATED THROUGH THE END OF THE WEEK. MEANWHILE
OVERALL RH VALUES SHOULD REMAIN ON THE LOW SIDE, AROUND 20-25%.
THIS COMBINED WITH THE LACK OF SIGNIFICANT PRECIPITATION SHOULD
HELP TO FUEL ELEVATED FIRE WEATHER CONCERNS, PRIMARILY IMPACTING
OUR HIGH PLAINS ZONES. WHILE THIS SHOULD KEEP US BELOW CRITICAL
FIRE WEATHER CONCERNS, ENHANCED FIRE WEATHER CONDITIONS WILL BE
PRESENT AND ANY FIRES THAT DO OCCUR WILL SEE A QUICK SPREAD. THERE
IS ALSO A CHANCE THAT RH VALUES WILL DECLINE EVEN LOWER ON FRIDAY,
BUT AT THIS TIME WE ARE NOT ANTICIPATING THE NEED FOR RED FLAG
WARNINGS, BUT WILL CONTINUE TO MONITOR THE LATEST UPDATES TO MODEL
DATA AS WE APPROACH THE END OF THE WEEK.
