FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
739 AM CDT FRI MAR 27 2026
MOST OF THE REGION NORTH OF I-70 IN MISSOURI AND ILLINOIS HAS
RECEIVED A WETTING RAIN OVERNIGHT WITH BREEZY NORTH TO NORTHEAST
WINDS BEHIND A SOUTHWARD MOVING COLD FRONT. THIS AFTERNOON,
EXPECT RELATIVE HUMIDITY VALUES TO FALL INTO THE MID 30% RANGE
WITH THE HIGHEST CONFIDENCE BEING ACROSS NORTHEAST MISSOURI AND
WEST- CENTRAL ILLINOIS. THIS IS THE AREA THAT RECEIVED THE
GREATEST RAINFALL TOTALS THOUGH, SO ANY FIRE WEATHER CONCERNS ARE
LIMITED TODAY.
ON SATURDAY, SURFACE HIGH PRESSURE WILL MOVE OVER EASTERN
MISSOURI AND WEST- CENTRAL ILLINOIS ALLOWING WINDS TO
SIGNIFICANTLY RELAX. BY THE AFTERNOON, HIGH PRESSURE WILL BE
APPROACHING THE MID-ATLANTIC REGION WITH WINDS OVER BI-STATE
TURNING FROM THE SOUTHEAST 5 TO 10 KT. RELATIVE HUMIDITY VALUES
WILL QUICKLY DROP INTO THE 15 TO 25% RANGE SATURDAY ACROSS
CENTRAL, EAST- CENTRAL, AND SOUTHEAST MISSOURI. THIS WILL SUPPORT
AN ELEVATED FIRE DANGER MAINLY SOUTH OF I-70 AND WEST OF THE
MISSISSIPPI RIVER.
