GO BIG OR GO HOME....
The all-time record low in Cedar Rapids is 29 below set in 2009. There's no doubt here (and in many other parts of the Midwest) lows will be within striking distance of that benchmark. It's a dubious honor but in my opinion if we're going to be that cold (and we will), it might as well be 30 below so we can set the record and make history. Afterall, what's another degree or two when it's that cold? Trust me, you won't know the difference.
One thing I do want to emphasize is how dangerous this type of extreme cold is. Exposed skin will freeze in less than 5 minutes, especially when wind chills reach minus 50. Pets and animals are also susceptible to these frigid conditions so please make sure they get the care and protection they need as well.
This is a timeline prepared by the NWS showing when wind chills will be at their worst.
