FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
446 AM CST THU DEC 25 2025
A QUASI-STATIONARY BOUNDARY IS EXPECTED TO MEANDER NORTH/SOUTH
OVER THE NEXT FEW DAYS AS IT BISECTS THE REGION. ALONG AND NORTH
OF THE FRONT, WARM AND HUMID AIR WILL OVERRUN A SHALLOW LAYER OF
COOLER AIR AT THE SURFACE. THIS WILL LEAD TO NIGHTLY EPISODES OF
FOG ALONG AND NORTH OF THE FRONT, WHILE WARMER AND RELATIVELY
MORE HUMID AIR RESIDES SOUTH OF THE FRONT. TEMPERATURE SPREADS OF
10-15 DEGREES WILL BE COMMON BETWEEN NORTHERN MISSOURI AND
WEST-CENTRAL ILLINOIS, SOUTHWARD THROUGH SOUTHERN MISSOURI AND
ILLINOIS. A STRONG COLD FRONT APPROACHES THE REGION FROM THE
NORTHWEST VERY LATE SATURDAY INTO SUNDAY. THE SPEED OF THE FRONT
REMAINS IN QUESTION WITH LATEST TRENDS FAVORING A LATER ARRIVAL.
THIS COULD KEEP ABOVE NORMAL WARMTH GOING THROUGH THE FIRST HALF
OF SUNDAY WITH INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS
FROM LATE MORNING THROUGH THE AFTERNOON. MUCH COLDER AIR ARRIVES
FOR NEXT WEEK.
