Extreme Cold Watch issued January 18 at 3:16PM EST until January 22 at 10:00AM EST by NWS Northern Indiana

* WHAT…Dangerously cold wind chills between 15 and 25 below zero
possible.

* WHERE…Portions of northern Indiana, southwest Michigan, and
northwest Ohio.

* WHEN…From late Sunday night through Wednesday morning.

* IMPACTS…The dangerously cold wind chills as low as 20 below zero
could cause frostbite on exposed skin in as little as 30 minutes.
Frostbite and hypothermia will occur if unprotected skin is
exposed to these temperatures.

* ADDITIONAL DETAILS…A period Monday into Monday night will be
able to warm into the single digits below zero which provides
additional uncertainty around wind chill magnitude. Time duration
of this relatively warm period and individual alignment of wind
and temperatures during the watch period are still uncertain. Lake
effect snow and accompanying cloud cover will also impact wind
chills during this time period insulating them like a blanket and
keeping those areas relatively warm.
