Green Bay, Wisconsin – Warmer temperatures arriving Friday could deteriorate ice and increase jam risks on area rivers.
According to the National Weather Service in Green Bay, a preview of spring will bring seasonally warm temperatures beginning Friday and continuing through the first half of next week. Highs this weekend are expected to reach the low to middle 40s across most of northeast Wisconsin.
Meteorologists say the warming trend will gradually weaken ice conditions on lakes and rivers. As ice begins to shift and break apart, the risk of ice jams may increase, particularly along area waterways feeding into Green Bay.
The 6-to-10-day temperature outlook indicates above-normal temperatures are likely across much of the Great Lakes region through the middle of next week. Forecasters also note that periods of stronger southeast winds early next week could increase the potential for ice movement and localized ice floes on Green Bay.
While no flooding is currently forecast, rapid ice deterioration can lead to sudden water level changes in vulnerable locations. Residents near rivers and streams are advised to monitor conditions closely as temperatures rise.
Drivers along Interstate 43, U.S. Highway 41, Interstate 41, Wisconsin Highway 29, and U.S. 141 near river crossings should remain alert for changing conditions, especially in low-lying or flood-prone areas.
The warming pattern marks a noticeable shift from recent colder conditions. Additional updates will be issued if ice movement or flooding concerns increase.
