FIRE WEATHER PLANNING FORECAST FOR CENTRAL/SOUTHEAST ILLINOIS
NATIONAL WEATHER SERVICE LINCOLN IL
421 AM CST TUE FEB 17 2026
DISCUSSION
STRONG LOW-LEVEL INVERSIONS AND SUBSEQUENT LOW MIXING HEIGHTS
WILL LIMIT VENT RATES TODAY. TODAY SOUTHERLY WINDS WILL INCREASE
WITH GUST OF 30-40 MPH THIS AFTERNOON INTO THE OVERNIGHT HOURS.
STRONG SOUTHWEST TRANSPORT WINDS WILL THEN ARRIVE TOMORROW,
LEADING TO GOOD VENT RATES; THOUGH, SOME CONCERN FOR RAPID FIRE
SPREAD COULD ARISE AS MINIMUM RH VALUES FALL BELOW 30% AND SURFACE
WIND GUSTS INCREASE TO 20-30 MPH.
SCATTERED RAIN SHOWERS ARE POSSIBLE (30-50% CHANCE) INTO
WEDNESDAY MORNING, THOUGH RAINFALL AMOUNTS LOOK FAIRLY PALTRY
(LESS THAN 0.10 INCH). THE BETTER CHANCE (50-60%) FOR RAIN AND
THUNDERSTORMS ARRIVES THURSDAY.
