Cold snap across the USA
The graphic is from the article: Vague de froid sur les Etats-Unis. Neige sur Houston et dans le nord du Mexique (Meteo World)
Cold temperatures reached all the way to the Mexican border. This cold air mass is apparently moving to the east. Saturday morning the low just north of Atlanta was in the lower 40's (4 C as shown above.) This morning, the front yard thermometer read 24.9 F. Temperatures stayed below freezing this morning until around noon or so and finally hit a high of 43 by 3 pm.
