INITIAL ALERTEmail
In response to the extreme cold, UW–Madison is canceling classes on Friday, January 23. Bitterly cold temperatures are expected to begin on Friday and continue into the weekend. An Extreme Cold Warning has been issued for Dane County from midnight to 1 p.m. Friday, with wind chills expected in the range of -30-40 F. The cancelation applies to all class meetings, including lectures, labs and discussion sections. If you have questions, please contact your instructor. Only classes are canceled. All other campus operations will continue as normal. Employees are expected to report to work as scheduled. If an employee's ability to report to work is impacted by the weather, employees should notify their supervisors and make alternative work arrangements or use leave time, depending on the situation. Campus buildings will be open during regular hours and all campus services, including University Housing, the Wisconsin Union and food services will operate normally. All UW Athletics events are expected to be held as scheduled, including Men's & Women's Hockey. Additional information for students If you need to be outside, limit your exposure and be aware of frostbite risks. Be sure to wear appropriate clothing. Wear layers of warm clothing, scarves, hats and gloves. Utilize Madison Metro for transportation and keep up to date on schedules and delays. Additional information for employees For more information, please review the campus Inclement Weather Policies or contact your supervisor or HR rep. To assist employees with transportation, parking permits will not be required Friday in campus lots 16, 26, 34, 45, 57, 59 and 60, or in off-campus lots 202, 204 and 206 which are serviced by shuttles. Refer to the campus parking map and lot addresses if needed. Please note that restricted areas are always enforced, such as signed reserved stalls, access aisles, and fire lanes. Note, only the chancellor or an authorized designee has the authority to suspend additional services, or close campus buildings.
Reconstructed from UW-Madison News and student-paper coverage; the cancellation of all class meetings 'including lectures, labs and discussion sections' is quoted from the university's announcement, but the precise WiscAlert SMS wording was not recovered.
The alert carefully separates class cancellation from campus closure: buildings, housing and dining stayed open and employees were still expected to report, a distinction UW-Madison stresses in its inclement-weather policy.
Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardabsent0/0

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationabsent0/0

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidanceabsent0/0

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Impactabsent0/0

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

About this analysis
Context

Background

The University of Wisconsin-Madison almost never cancels classes for weather; before January 23, 2026, the last weather cancellation was the January 2019 polar vortex. An Extreme Cold Warning for Dane County, with wind chills forecast at -30 to -40 degrees Fahrenheit, prompted the university to notify students Thursday evening via WiscAlert that all Friday classes were canceled. The cancellation applied to every class meeting, but per UW-Madison's inclement-weather policy, campus buildings, University Housing, the Wisconsin Union and food services remained open and employees were expected to report. The Daily Cardinal reported that a student Change.org petition had circulated ahead of the decision. WiscAlert and the campus alerts website are the university's authoritative channels for these notifications.
