FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
649 PM CST SAT DEC 13 2025
VERY LOW TEMPERATURES AND DANGEROUS WIND CHILLS ARE EXPECTED
OVERNIGHT AND TOMORROW MORNING, WITH BREEZY NORTH WINDS.
TEMPERATURES SUNDAY AFTERNOON AND MONDAY MORNING WILL BE SLIGHTLY
WARMER, BUT IT WILL REMAIN VERY COLD OVERALL. TEMPERATURES ARE
LIKELY TO RISE 30 TO 35 DEGREES DURING THE DAY MONDAY, WITH LOW
HUMIDITY AND BREEZY SOUTHWEST WINDS ALSO EXPECTED. THIS MAY
SUPPORT LOCALLY ERRATIC FIRE BEHAVIOR IN SOME PARTS OF THE OZARKS
AND SOUTHWEST ILLINOIS, BUT BECAUSE MORNING TEMPERATURES WILL BE
SO COLD AND TEMPERATURES WILL RISE SO QUICKLY, MOST FUELS ARE NOT
LIKELY TO BE RECEPTIVE. TEMPERATURES AND HUMIDITY WILL BOTH
QUICKLY RISE TUESDAY AND WEDNESDAY, WITH INCREASING RAIN CHANCES
EARLY THURSDAY.
