FIRE WEATHER PLANNING FORECAST FOR EASTERN/CENTRAL MO AND SOUTHWEST IL
NATIONAL WEATHER SERVICE SAINT LOUIS MO
506 PM CST SUN JAN 18 2026
ARCTIC AIR WILL REMAIN IN PLACE THROUGH MONDAY BEFORE WARMING TO
NEAR NORMAL TEMPERATURES TUESDAY. DESPITE A DROP IN RELATIVE
HUMIDITY MONDAY, WINDS BEGIN TO DECREASE, REDUCING FIRE RISK,
ESPECIALLY GIVEN THE ARCTIC AIR THAT IS NOT CONDUCIVE FOR
WILDFIRES. BY MIDWEEK, A WARM FRONT DRAWS MILDER AIR INTO THE
REGION, AS SURFACE WINDS TURN OUT OF THE SOUTHWEST. TEMPERATURES
BRIEFLY BECOME SEASONABLY WARM AHEAD OF ANOTHER REINFORCING SHOT
OF COLD AIR THURSDAY. DRY CONDITIONS EXTEND THROUGH FRIDAY, WHEN
A STRONG ARCTIC FRONT BRINGS WHAT HAS THE POTENTIAL TO RIVAL SOME
OF THE COLDEST AIR OF THE SEASON SO FAR. PRECIPITATION CHANCE
INCREASE LATE FRIDAY INTO NEXT WEEKEND, BUT SPECIFIC DETAILS
REMAIN UNCERTAIN.
