FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
348 AM CST TUE DEC 30 2025
DISCUSSION
A PAIR OF CLIPPER SYSTEMS WILL PROVIDE A COUPLE
SHOTS OF ACCUMULATING SNOW TO END 2025. THE FIRST ONE IS THIS
AFTERNOON/EVENING. DRY AIR ALOFT MIXING IN WITH THE SYSTEM SHOULD
LIMIT ACCUMULATIONS FROM A DUSTING TO LESS THAN AN INCH.
ON NEW YEARS EVE, THE NEXT SYSTEM HAS A BETTER CHANCE FOR
ACCUMULATIONS LOCALLY OVER AN INCH IN THE AFTERNOON AND EARLY
EVENING. BLUSTERY CONDITIONS CAN ALSO BE EXPECTED WITH THE SNOW
WITH NORTHWEST WIND GUSTS UP TO 30 MPH.
ANOTHER SHOT OF COLDER, DRIER AIR IS EXPECTED ON NEW YEARS DAY,
BEFORE MODERATING TEMPERATURES THROUGH THE WEEKEND.
