FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
434 PM CDT THU MAR 19 2026
DISCUSSION
A LAKE BREEZE CONTINUES TO WORK INLAND ACROSS THE CHICAGO METRO
AREA THIS AFTERNOON WHICH IS RESULTING IN 10-12 MPH EASTERLY WINDS
AND HIGHER HUMIDITIES (AROUND 45-50%) IN ITS WAKE. WHILE THE LAKE
BREEZE COULD GET AS FAR INLAND AS AURORA, IT SHOULD BEGIN TO LOSE
STEAM A WE APPROACH SUNSET. ELSEWHERE, EXPECT A WARM SPRING
AFTERNOON WITH RH VALUES AROUND 30-35% AND LIGHT EAST-SOUTHEAST
WINDS AROUND 5-10 MPH THROUGH SUNSET. FOR TONIGHT EXPECT CLOUD
COVER TO GRADUALLY INCREASE WITH RH VALUES IMPROVING TO 90-98%
OVERNIGHT AS TEMPERATURES COOL NEAR THE DEW POINTS. WINDS WILL
REMAIN LIGHT AND BECOME MORE SOUTHWESTERLY OVERNIGHT.
FRIDAY WILL START WITH PARTLY TO MOSTLY CLOUDY SKIES AND
SOUTHWESTERLY WINDS OF 10 TO 15 KT. A WEAK FRONT WILL MOVE THROUGH
THE AREA DURING THE MORNING LEADING TO A NORTHWESTERLY WIND
SHIFT. SIMILAR TO TODAY, TEMPERATURES AND MIXING HEIGHTS WILL BE
MOST STUNTED NEAR LAKE MICHIGAN DUE TO A LAKE BREEZE THAT WILL
MOVE INLAND LATE IN THE AFTERNOON.
THIS WEEKEND WILL OFFER A CONTINUATION OF SPRING-LIKE CONDITIONS
WITH WARM TEMPERATURES AND SOUTHWESTERLY WINDS. A COLD FRONT WILL
MOVE THROUGH AT SOME POINT ON SUNDAY, HOWEVER, POTENTIALLY LEADING
TO WIDELY VARYING TEMPERATURES AND WINDS ACROSS THE REGION.
NO WIDESPREAD OR SOAKING RAIN IS IN OUR FORECAST THROUGH AT LEAST
THE NEXT SEVEN DAYS.
