It is cold across the nation. The only place “warm” is south Florida. Here are the temperatures as of 7 PM from the Oklahoma Mesonet.
The jet stream is in a large “U” shape or trough and this is allowing the cold air across the nation.
We are dealing with the coldest air of the season so far and it is cold enough to break record cold highs and record lows for November. The first graphic is from today (Nov 17). A record cold high was set in Waterloo. The NWS does not have any record data for Cedar Rapids or Iowa City.
Now tonight temperatures are expected to drop to near zero by morning with wind chills of 10 to 20 below zero. The forecast lows are all new record lows for Tuesday (Nov 18)
Starting out is a deep “temperature hole” it will be hard to get out. High temperatures again will be in the teens with a better chance of both Waterloo and Dubuque breaking the record cold highs for Tuesday (Nov 18)
Every state in the lower 48 will have a low temperature below freezing Tuesday morning.
