NEW INFORMATION ADDED TO UPDATE SECTION
UPDATE
ISSUED AT 918 PM CDT MON MAR 16 2026
DECREASING WINDS AND INCREASING VSBYS ACROSS NORTHERN DOOR COUNTY
INDICATE THAT BLIZZARD CONDITIONS HAVE WANED, SO HAVE DOWNGRADED
TO A WINTER WEATHER ADVISORY TO COVER ANY LINGERING
BLOWING/DRIFTING SNOW FOR THE REST OF THE EVENING. ALLOWED THE
WINTER WEATHER ADVISORIES TO EXPIRE IN THE FOX VALLEY AND OTHER
LAKESHORE COUNTIES AT 9 PM, AS WIND GUSTS HAVE GENERALLY DROPPED

STRONG WINDS GUSTING TO 45 MPH ACROSS NORTHERN DOOR COUNTY WILL
LIKELY PRODUCE BLIZZARD CONDITIONS THERE FOR A FEW MORE HOURS. WINDS

ROAD REPORTS BEFORE TRAVELING. THE CURRENT HEADLINES AND HEADLINE
TIMING REFLECT THESE THOUGHTS, AND THE WSW STATEMENT WILL BE
UPDATED AS HEADLINES DROP OFF.
