FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN...UPDATED
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
446 AM CDT MON MAY 12 2025
DISCUSSION
UPPER LEVEL LOW PRESSURE OVER THE LOWER MISSISSIPPI VALLEY WILL
SLOWLY LIFT NORTH THROUGH MIDWEEK. THIS MAY BRING ISOLATED TO
WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS AT TIMES THIS
AFTERNOON THROUGH WEDNESDAY. WARM, ABOVE NORMAL HIGH TEMPERATURES
WILL CONTINUE INLAND OF LAKE MICHIGAN, WITH INCREASED HUMIDITY
LEVELS AS WELL TONIGHT ONWARD. ONSHORE WINDS WILL KEEP AFTERNOON
TEMPERATURES COOLER AND MIXING HEIGHTS LOWER NEAR THE LAKE. ON
THURSDAY, VERY WARM TO HOT, HUMID, AND BREEZY CONDITIONS MAY SET
THE STAGE FOR THUNDERSTORM DEVELOPMENT (POSSIBLY SEVERE) AHEAD OF
A COLD FRONT INTO THE EVENING. BEHIND THE COLD FRONT ON FRIDAY,
THE POTENTIAL EXISTS FOR STRONGER THAN CURRENTLY FORECAST WEST-
SOUTHWEST WINDS ALONG WITH WARM TEMPERATURES AND LOW RH, WHICH
MAY YIELD AN ELEVATED FIRE DANGER. COOLER AND PRIMARILY DRY
CONDITIONS ARE EXPECTED INTO THE WEEKEND.
