Clear Skies that caused the cold temps the morning of January 21st

It was a very cold morning across the local area this morning, Most places were at least in the 20 degree below zero range, some places were as cold as the upper 30s below zero! The reason for the cold temperatures is a strong arctic cold front that went thought yesterday afternoon. The front moved well east and the skies that once had some clouds in them Thursday afternoon became crystal blue clear with not a cloud in the sky by evening. To add to this it was a full moon and winds were fairly light. This was a perfect set up for temperatures to plummet, and plummet they did!

By sunset Thursday my thermometer was already at zero. and by 12AM it was already -16.F My station bottomed out at a low of -23.F, Which was 1 degree from reaching a tie with my stations 3 year record cold temperature of -24.F set in 2008 The coldest wind chill reading from my station was -33.F

Reported lows.

The coldest reports came from traditional Northern area cold spots, Minong had a stunning low of -38.F below zero! While the warmest if you can call it “warm” was -19.F in Knapp. This was the coldest night of the Winter so far for the local area. Hopfully there wont be too many nights like this!
