Good afternoon all!…Due to a change in my work schedule, I will not be updating on Wed., Thu., and Fri.
EXTREMELY cold Arctic air will continue to spread over the U.S. during the next 48 – 72 hours. This will be some of the coldest air we have seen thus far, and will push deeper into the south, with a great majority of the U.S. experiencing freezing to below freezing minimum temperatures during the next 3 days. In fact, the freezing line (32f), depicted by the solid, dark blue line on the surface map, extends down into the Florida Panhandle by Thursday. Some snow will continue through tonight around the Great Lakes area, NY State, and PA, which should begin to taper off late tonight / very early Wed. morning, with another short period on Thur. Temperatures will begin to slowly modify by Fri., with warmer Minimum temperatures occurring over the far south by Sat.
The following maps are comparison maps of the GFS and NAM models from 12Z this morning, regarding forecast station minimum temperature plots. Bear in mind, these projected minimum temperatures DO NOT take into account the wind chill. You may keep track of Wind Chill by using the Intellicast Wind Chill map, and scrolling at the bottom of the map to see forecast wind chill temperatures. Sub zero wind chills are forecast over most of the nation.

Even though they have fur, they get cold just as we do, and will die from exposure and hypothermia! Here is an article from the ASPCA regarding pets and cold weather:
