FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1006 AM CDT TUE MAY 13 2025
DISCUSSION
- ELEVATED TO POTENTIALLY SIGNIFICANT FIRE DANGER POSSIBLE ON
FRIDAY.
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE THIS
AFTERNOON AND AGAIN ON WEDNESDAY AFTERNOON. WARM, ABOVE NORMAL
HIGH TEMPERATURES WILL CONTINUE INLAND OF LAKE MICHIGAN. ONSHORE
WINDS WILL KEEP AFTERNOON TEMPERATURES COOLER AND MIXING HEIGHTS
LOWER NEAR THE LAKE.
ON THURSDAY, HOT, MODERATELY HUMID, AND BREEZY CONDITIONS MAY SET
THE STAGE FOR THUNDERSTORM DEVELOPMENT (POSSIBLY SEVERE) AHEAD OF
A COLD FRONT LATE IN THE AFTERNOON INTO THE EVENING. THEN ON
FRIDAY, THE POTENTIAL EXISTS FOR STRONG WEST-SOUTHWESTERLY WINDS
GUSTING ABOVE 40 MPH, ALONG WITH AFTERNOON RH VALUES FALLING BELOW
25 PERCENT, WHICH MAY YIELD ELEVATED TO RED FLAG FIRE CONDITIONS.
THE CURRENT FORECAST HAS AFTERNOON RH IN THE 20-30% RANGE, BUT
THE RANGE OF PLAUSIBLE OUTCOMES IS STILL LARGE, FROM 10-20% ON THE
LOW SIDE TO 30-40% ON THE HIGH SIDE. WITH THAT SAID, THE MOST
CONSISTENT MODEL GUIDANCE GENERALLY SUPPORTS THE LOWER RH AND
STRONGER WIND SCENARIO. CLOSELY MONITOR FORECAST TRENDS IN THE
COMING DAYS.
THEREAFTER, COOLER AND PRIMARILY DRY CONDITIONS ARE EXPECTED INTO
THE WEEKEND. SATURDAY WILL FEATURE BREEZY WESTERLY WINDS, BUT NOT
AS STRONG AS FRIDAY, AND RH DOWN AS LOW AS 30-40%.
