It is supposed to be cold tonight.  REALLY cold!  There's a Wind Chill Advisory until 9 AM tomorrow (Sunday) morning and the National Weather Service says the temp will get down to -3, but feel like -20 with the wind chill.

Obviously, you should probably stay inside tonight, but if you need to go outside, please be cautious about frostbite and hypothermia.

Here is a video about treating frostbite

And, here's one about hypothermia

Please be safe
