The coldest temperatures of the season will blow through North Texas in the coming days. A powerful arctic blast partly tied to the polar vortex will bring frigid, bone-chilling weather to Dallas-Fort Worth through at least midweek next week.

The looming arctic air is putting a freeze on Fort Worth’s annual MLK Day parade. The annual Greater Fort Worth Martin Luther King Jr. Holiday Parade and Rally has been postponed due to weather concerns.

Meteorologists are estimating Dallas-Fort Worth will get snow next week, but the light accumulations won’t surpass a half an inch. The National Weather Service in Fort Worth predicts North Texas will have “some” winter precipitation early-to-mid next week.
