So far for the 2014-2015 winter season in the metro, the coldest low temperature has been -11°, and that was just the other day. Now, the Upper Midwest is set to encounter our coldest temperatures yet.
There are several factors working in our favor, if you're routing for the cold that is. High pressure will bring some downright cold air in from Canada. Also, unlike the cold on a wake of a snow system, we will have clear skies to start. Plus, we are already cold, with temperatures below zero, instead of in the lower 30s, like they were before the last cold snap. Check out the forecast wind chills for early Tuesday morning.
When temperatures are as cold as they are forecast to be, then you don't need much of a breeze to have dangerous wind chill values. Frostbit can occur on exposed skin in less than 10 minutes, so make sure you cover all your cracks and crevices if your out and about.
Here is an interactive website from NOAA that allows you to calculate the wind chill for your neck of the woods. All you need is the temperature and wind speed. http://www.nws.noaa.gov/om/winter/windchill.shtml
To add insult to injury, this cold snap will have our temperatures at about 25 degrees below average.
Wouldn't normal be nice right about now?
