FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
1244 PM CDT SAT MAR 21 2026
VERY WARM TEMPERATURES AND SEASONABLY LOW MOISTURE WILL LEAD TO
MINIMUM RH OF 20 TO 35 PERCENT ACROSS THE AREA. SPORADIC ELEVATED
FIRE DANGER IS EXPECTED ACROSS NORTHEASTERN MO/WEST-CENTRAL IL
WHERE SOUTHWESTERLY WINDS WILL BE STRONGEST, AROUND 10 TO 12 MPH
AT TIMES. MIXING HEIGHTS WILL BE EXCEPTIONALLY DEEP THIS
AFTERNOON, PROMOTING OVERALL GOOD SMOKE DISPERSION, DESPITE SOME
LIMITATION FROM LIGHT WINDS. SIMILARLY WARM TEMPERATURES, MINIMUM
RH OF 25 TO 35 PERCENT, AND SOUTHWESTERLY WINDS WILL LIKELY LEAD
TO ELEVATED FIRE DANGER IN SOUTHEASTERN/EAST-CENTRAL MO SUNDAY
AFTERNOON AHEAD OF AN APPROACHING COLD FRONT. ALTHOUGH WINDS WILL
BE STRONGER ELSEWHERE AND BEHIND THE FRONT AFTER THE VEER TO
NORTHERLY, RH WILL GENERALLY BE HIGHER (35 TO 50 PERCENT) WITH
GREATER MOISTURE AND COOLING TEMPERATURES AFTER THE FRONT PASSES.
THERE IS ALSO A 20 TO 30 PERCENT CHANCE OF SHOWERS AND
THUNDERSTORMS SUNDAY EVENING IN SOUTHEASTERN MO/SOUTHWESTERN IL.
NEAR AVERAGE TEMPERATURES WILL WARM BACK TO WELL-ABOVE AVERAGE
MONDAY THROUGH THURSDAY, BUT MOISTURE WILL BE SLOWER TO INCREASE
WITH MINIMUM RH AROUND 30 TO 45 PERCENT MONDAY AND TUESDAY
AFTERNOONS.
