As a slug of arctic air overtakes the eastern two-thirds of the U.S. next week, a storm system could bring snow, sleet and freezing rain to places deep in the heart of Texas, but the forecast isn’t a lock just yet.

Lows Tuesday morning were in the 20s and lows Wednesday are expected to be in the 30s, an improvement but it's still cold. North Texas should see highs rebound into the 60s on Thursday and Friday, but it's short-lived.

Enjoy the next couple of mild days before the bitter cold returns to North Texas this weekend. Highs will reach the low 60s on Thursday and Friday, but overnight lows will drop into the 20s.
