FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
1020 PM CST SUN DEC 14 2025
WHILE ANOTHER VERY COLD MORNING IS EXPECTED TOMORROW, BREEZY
SOUTHWESTERLY WINDS WILL DRIVE A 30-35 DEGREE WARMUP BY MID
AFTERNOON. HUMIDITY WILL ALSO BE VERY LOW IN SOME AREAS,
ESPECIALLY ACROSS THE OZARKS. WHILE THIS WOULD ORDINARILY SUPPORT
ERRACTIC FIRE BEHAVIOR, IT IS UNLIKELY THAT MOST FUELS WILL BE
ABLE TO WARM UP AND DRY FAST ENOUGH TO BE ESPECIALLY RECEPTIVE TO
FIRE, CONSIDERING HOW QUICKLY TEMPERATURES WILL RISE.
TEMPERATURES WILL CONTINUE TO WARM TUESDAY AND WEDNESDAY AND
SOUTHWESTERLY WINDS WILL CONTINUE, BUT HIGHER HUMIDITY AND
SLIGHTLY LOWER WINDS SPEEDS ARE ALSO EXPECTED. THURSDAY WILL
FEATURE ACTIVE WEATHER, WITH A ROUND OF SHOWERS AND BREEZY SOUTH
WINDS EARLY IN THE DAY, FOLLOWED BY A COLD FRONT AND STRONGER
WESTERLY WINDS LATER IN THE DAY.
