‘Blue Norther’ Expected To Bring 30-Degree Temperature Drop Overnight Friday

National Weather Service

Temperatures in North Texas are expected to take a deep dive this weekend. The National Weather Service is predicting a high temperature near 70 on Friday, with lows Friday night reaching down to 35 as a strong cold front moves through late Friday afternoon and into Friday night. The front carries with it a chance of showers and thunderstorms, the service stated.

The deep chill takes effect early Saturday, as temperatures are on track to continue dropping as an arctic front surges south into the area. Saturday’s high is expected to be near 41, with a low Saturday night in the 20s. Winds could gust as high as 40 mph.

The high temperature Sunday is forecasted to be 48 degrees, while the low Sunday night will be around 38. Winds from the north-northwest from 5 to 15 mph could gust as high as 25 mph.

A Blue Norther, also known as a Texas Norther, is a fast moving cold front marked by an exceptionally rapid drop in temperature, strong winds, and dark blue or "black" skies, according to the weather service.  The cold front originating from the north can send temperatures plummeting by anywhere from 20 to 40 degrees in minutes.
