FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
128 AM CDT WED APR 22 2026
AFTERNOON TEMPERATURES ACROSS THE AREA HAVE REACHED THE LOWER
80S, AIDED BY GUSTY SOUTHWESTERLY WINDS THAT WILL CONTINUE THIS
AFTERNOON BEFORE FADING AROUND SUNSET THIS EVENING. THE LOWEST RH
VALUES TODAY ARE FORECAST TO BE ACROSS THE OZARKS AND FAR
SOUTHERN MO WHERE VALUES BELOW 30 PERCENT ARE POSSIBLE. DEEP
MIXING COMBINED WITH THE GUSTY WINDS WILL ALSO SUPPORT EFFICIENT
SMOKE DISPERSION. A WEAK COLD FRONT STALLS NEAR NORTHERN
MO/WEST-CENTRAL IL LATE THIS EVENING AND BRINGS A LOW CHANCE
(10-20%) FOR SCATTERED SHOWERS AND THUNDERSTORMS FOR THOSE AREAS.
WARM TEMPERATURES WITH WEAKER SOUTHWESTERLY WINDS CONTINUE
TOMORROW AS MOISTURE IS STEADILY ON THE INCREASE. SOUTH WINDS ARE
STRONGER ON THURSDAY WITH AN APPROACHING COLD FRONT THURSDAY
AFTERNOON BRINGING WIDESPREAD SHOWER AND THUNDERSTORM CHANCES
THURSDAY NIGHT INTO FRIDAY. MOST OF THE WEEKEND IS EXPECTED TO BE
DRY WITH LESS THAN 20% CHANCE FOR MEASURABLE PRECIPITATION. RAIN
CHANCES RETURN AGAIN LATE SUNDAY LASTING INTO EARLY NEXT WEEK.
