FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
346 PM CDT SAT MAR 21 2026
DISCUSSION
A WARM AND BREEZY AFTERNOON IS UNDERWAY AND WILL PERSIST THROUGH
SUNSET WITH TEMPERATURES IN THE MID TO UPPER 70S (UPPER 60S NEAR
THE LAKE) AND SOUTHWESTERLY GUSTS AROUND 20-25 MPH. RH VALUES HAVE
DIPPED INTO THE 30-35% RANGE ACROSS MOST OF THE AREA (LOCALLY
HIGHER NEAR THE IL-WI LINE) AND THESE READINGS ARE EXPECTED TO
PERSIST THROUGH SUNSET BEFORE RECOVERING INTO THE 75-85% RANGE
OVERNIGHT. GUSTS WILL GRADUALLY DIMINISH OVERNIGHT BUT SOME
OCCASIONAL 15-20 MPH GUSTS WILL REMAIN POSSIBLE WITH WIND
DIRECTIONS BECOMING MORE WEST-NORTHWEST.
A COLD FRONT ASSOCIATED WITH A LOW PASSING TO OUR NORTH TODAY
WILL SURGE SOUTHWARD LATE TONIGHT INTO SUNDAY MORNING, RESULTING
IN A BLUSTERY, COLDER, CLOUDY AND POSSIBLY DAMP DAY ON SUNDAY.
TEMPERATURES WILL STRUGGLE TO CLIMB OUT OF THE 40S THROUGH THE
DAY. ADDITIONALLY, AN AXIS OF LIGHT RAIN OR DRIZZLE MAY SPREAD
OVER THE AREA DURING THE DAY (20-30% CHANCE).
COOLER CONDITIONS ARE EXPECTED EARLY NEXT WEEK FOLLOWED BY A
WARMING TREND MIDWEEK. CHANCES FOR APPRECIABLE PRECIPITATION
REMAIN LOW THROUGH THE FORECAST PERIOD.
