High quality snow

The importance of the wind chill index is as an indicator of how to dress properly for winter weather. Wind chill does not affect your car's antifreeze protection, freezing of water pipes, etc. In dressing for cold weather an important factor to remember is that entrapped insulating air warmed by body heat is the best protection against the cold. Consequently, wear loose-fitting, lightweight, warm clothing in several layers. Outer garments should be tightly-woven, water-repellant and hooded. Mittens snug at the wrist are better protection than fingered gloves.

Wind speeds greater than 40 mph have little additional effect on chilling. In using the table below, values of wind chill below -10° F are considered bitterly cold. Values of wind chill below -20° F are extremely cold -- human flesh will begin to freeze within one minute!

According to the latest short term computer model, the warm air advection snow is maximized over the Twin Cities from around 10am to 3pm. We could tally more than an inch of high quality snow. Be cautious on the roadways.

When is the temperature bitter cold for you?
