WISCONSIN issued its second blizzard warning of the year this past weekend — the first coming before 8 inches of snow hit Sheboygan on Dec. 1 — an EXTREMELY UNCOMMON occurrence. "We usually issue a blizzard warning probably once every five years. It's pretty RARE." This is the first time since 1999 the weather service has issued a blizzard warning for its entire coverage area. The warnings are issued when the weather service expects sustained winds of at least 35 mph combined with falling snow for at least a three-hour period.
