FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
1126 AM CST MON JAN 12 2026
A WARMING TREND BEGINS TODAY, AND PEAKS ON TUESDAY AS HIGHS CLIMB
INTO THE MID 50S TO MID 60S FROM NORTH TO SOUTH. MINIMUM RELATIVE
HUMIDITY VALUES OF 30-50 PERCENT ARE FORECAST EACH DAY, WITH THE
LOWEST VALUES IN SOUTHEAST MISSOURI. SOUTHWEST WINDS ARE ALSO
EXPECTED TO PICK UP SLIGHTLY ON TUESDAY, WITH SPEEDS IN THE
10-15 MPH RANGE. THE WEAKEST WINDS HOWEVER ARE LIKELY TO BE IN
PARTS OF SOUTHEAST MISSOURI, SO ELEVATED FIRE DANGER IS
QUESTIONABLE GIVEN THESE WEAK WINDS ANTICIPATED. COLDER
TEMPERATURES, BACK CLOSER TO NORMAL, ARE FORECAST FOR THE
REMAINDER OF THE WORK WEEK.
