FIRE WEATHER PLANNING FORECAST FOR CENTRAL/SOUTHEAST ILLINOIS
NATIONAL WEATHER SERVICE LINCOLN IL
320 AM CDT MON APR 27 2026
DISCUSSION
SEVERAL ROUNDS OF THUNDERSTORMS ARE EXPECTED TODAY, SOME OF WHICH
COULD BE STRONG TO SEVERE. THE CHANCE OF STORMS HAS INCREASED FOR
THIS MORNING INTO EARLY AFTERNOON. NOT ONLY WILL THIS LEAD TO WET
FUELS, BUT IT WILL LIMIT MIXING HEIGHTS AND WIND GUSTS COMPARED TO
PREVIOUS FORECASTS. BREEZY SOUTHERLY WINDS ARE STILL EXPECTED TO
GUST 30-40 MPH AT TIMES TODAY, BUT VENTILATION WILL JUST BE FAIR
DUE TO THE REDUCED MIXING. AS A COLD FRONT MOVES THROUGH THIS
EVENING, WINDS WILL SHIFT FROM SOUTHERLY TO WEST-NORTHWESTERLY.
ANOTHER CHANCE OF RAIN ARRIVES TUESDAY EVENING, ESPECIALLY SOUTH
OF I-72.
