Hundreds of brave people are mentally preparing to take the plunge into Lake Superior as part of the Duluth Polar Plunge for Special Olympics of Minnesota. Temperatures have been warming up this week, but will they hold out through plunge day?

Here's the breakdown for plunge day (Saturday, February 20):

Polar Plunge 5K Run (9:00 am)

Cloudy with an air temperature of 36 degrees. A NW wind around 10 mph will make for wind chill values that will feel more like 29 degrees.

Polar Plunge into Lake Superior (2:00 pm)

Mostly cloudy with an air temperature of 39 degrees. A NW wind around 10 pm will continue through the day, making it feel more like 33 degrees. These conditions should hold through the duration of the plunge, with a chance of seeing the sun from time to time.
