Frigid overnight temps and howling wind

Wowee! It was one cold day! The temp. did not rise above 6F and the "high" windchill was -10F. Watch out for tonight. When I went to bed, the temp. was 1.2F with a windchill of -20F! Overnight temps. here, will probably dip down to a windchill of -25F. It is dangerous outside.
