Full house at the Wisconsin Climate Services Summit, hosted by Wisconet and the @WI_ClimateSCO. Having good conversations with users of weather and climate data, and learning what sort of services they want from us.

Share this information far and wide: stay home and stay safe! This is a rapidly evolving, life-threatening situation. Northern WI counties are severely impacted by the winter storm. Many roads are impassable and travel is not advised across the majority of northern counties.

8:30 pm: This winter storm is impacting a large portion of the region with much of Wisconsin under Blizzard Warnings. Conditions will deteriorate overnight. Stay safe!

🌨️Confidence continues to increase in a major winter storm producing a swath of heavy snow from the northern High Plains to the Great Lakes this weekend. Whiteout conditions & exceptional snowfall rates will cause dangerous to even impossible travel conditions at times.

{3/12/26} 7 AM ‼️Confidence continues to increase for a significant winter storm (12+ inches of snow) this weekend. Winds gusting in excess of 40 mph may result in near blizzard conditions and widespread hazardous travel. Be sure to stay tuned to the latest forecast! #wiwx

An updated Day 3-7 Hazards Outlook has been issued. wpc.ncep.noaa.gov/threats/threat…

Storms are expected to develop between 4 PM and 7 PM today. Any storms that form initially will have the best chances for large hail. Storms will then continue through the evening, mostly ending by midnight. #swiwx
