A look at tonight’s temperature map across the country reveals a very cool airmass that has overspread much of the country. But the more telling map is this one, the WWA map from the National Weather Service (That’s Watch, Warning, and Advisory).

Freeze warnings are up for a big chunk of the country, indicating many areas may see their first freeze of the season tonight as temperatures dip. There’s still time to get your sensitive plants indoors and make sure your pets have a warm place to sleep through the winter.

I’ll be the sleepy storm chaser hibernating until the next severe weather setup.
