Patchy Frost possible in parts of western and central Wisconsin

We were warming up nicely as we got a little sunshine between the morning rain and the afternoon round. This allowed temperatures to climb towards 70, but they quickly fell by almost 15 degrees when the afternoon shower rolled through Eau Claire. We’ve recovered a bit after they moved out, but still our temperatures are only in the 60s.

This is the starting point for falling temperatures tonight. With a clear sky, light winds, and low dew points, the atmosphere should have no problem allowing temps to drop into the upper 30s, especially north and east of Eau Claire. This is near the edge of frost formation.

It’s likely that a isolated spots within northwestern and central Wisconsin’s colder areas drop into the mid 30s. Typically, frost starts to form around an air temperature of 36 to 37 degrees. and becomes likely at or below 34 degrees. While this doesn’t look likely for Eau Claire, rural areas north and east could see a few spots with lows in the upper 30s, perhaps briefly at 35 or 36.

Protect or bring in plants if you live in these typically cool spots tonight just to be safe.

After the chilly start, sunshine tomorrow will help warm us back up into the 70s, and humidity will continue to be nonexistent. More showers move in Friday and Saturday and temperatures have a chance at the upper 70s again next week, with more lower end chances for rain.
