The National Weather Service Milwaukee/Sullivan Weather Forecast Office has issued a Cold Weather Advisory from 10 p.m. on Wednesday to 10 a.m. on Thursday. They indicate that “The combination of air temperatures in the low single digits to negative single digits and wind gusts between 35 to 40 mph will lead to wind chills as low as -25 degrees. Wind chills will be the worst between Midnight and 8AM Thursday.”

The former Wind Chill Advisories are now being called “Cold Weather Advisories.” Such an advisory is issued when the wind chill is anticipated to be at least -20 degrees F. It appears that much of Rock and Walworth Counties will barely miss falling to that level, and consequently the advisory is not being extended to them – but it will still be very cold.
