Overview
- National Weather Service freeze warnings and watches are in effect in several regions, with first-of-season freezes likely from North Texas to parts of the Southeast and northern Florida.
- Gusty winds commonly 20–40 mph will drive wind chills into the teens and 20s in many areas, with the coldest conditions expected Monday night into Tuesday.
- Great Lakes snowbelts face lake-effect snow and narrow squalls from Sunday night through Tuesday, with localized totals reaching several inches and over a half-foot where bands persist.
- Wet, heavy snow and blustery conditions could down tree limbs and create slick spots on bridges and overpasses in affected snowbelt zones.
- The Arctic air is expected to be short-lived, with temperatures rebounding quickly by midweek into the 60s and 70s and elevated fire-weather risk noted in drought-stricken parts of Southeast Texas.
