FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
449 AM CDT FRI APR 3 2026
DISCUSSION
BREEZY WEST WINDS WILL DIMINISH THROUGH MIDDAY TODAY, AS AN AREA
OF WEAK HIGH PRESSURE BUILDS IN BEHIND LAST NIGHTS COLD FRONT.
WINDS WILL TURN EASTERLY THIS AFTERNOON AS THE HIGH DEPARTS, AND
WILL BECOME BREEZY AGAIN TOWARD EVENING. ONSHORE FLOW WILL MAKE
FOR COOLER CONDITIONS AND LOWER MIXING HEIGHTS DOWNWIND OF LAKE
MICHIGAN ACROSS NORTHEAST ILLINOIS AND PARTS OF NORTHWEST INDIANA.
FARTHER SOUTH, LAST NIGHTS COLD FRONT WILL BEGIN TO RETURN NORTH
AS A WARM FRONT LATER THIS AFTERNOON, LIFTING TO ABOUT A PONTIAC
TO RENSSELAER LINE BY EVENING. ALONG AND SOUTH OF THE WARM FRONT,
TEMPERATURES WILL WARM INTO THE 70S WITH MORE HUMID CONDITIONS.
ISOLATED TO SCATTERED THUNDERSTORMS ARE POSSIBLE IN THE VICINITY
OF THE WARM FRONT THIS AFTERNOON AND EARLY EVENING, A FEW OF WHICH
COULD BE SEVERE.
ANOTHER WEATHER DISTURBANCE AND ASSOCIATED LOW PRESSURE SYSTEM
WILL APPROACH THE AREA TONIGHT AND MOVE THROUGH THE AREA EARLY
SATURDAY, AND WILL BRING ANOTHER ROUND OF RAIN AND THUNDERSTORMS
TO THE AREA. SOME LOCALLY HEAVY RAINFALL AMOUNTS ARE POSSIBLE WITH
SOME OF THESE STORMS THIS EVENING INTO THE OVERNIGHT HOURS, IN
ADDITION TO THE POTENTIAL FOR SOME ISOLATED HAIL AND DAMAGING
WINDS. SHOWERS AND STORMS WILL END FROM WEST TO EAST EARLY
SATURDAY MORNING, THOUGH A FEW SPRINKLES OR LIGHT SHOWERS ARE
POSSIBLE IN THE AFTERNOON. BLUSTERY AND COOLER WEATHER IS EXPECTED
SUNDAY. COOL AND DRY WEATHER WILL PERSIST THROUGH EARLY NEXT
WEEK, BEFORE MILDER AND POTENTIALLY MORE ACTIVE WEATHER RETURNS
BEYOND MID-WEEK.
