Hail, even a gustnado or two possible with new line of storms headed for Dallas-Fort Worth

A disturbance high in the atmosphere, or a shortwave trough, is moving on a line from the U.S. Southwest to the Rockies heading east and by Thursday afternoon will reach the Great Plains including the Dallas-Fort Worth region, according to the National Weather Service Fort Worth office report.

This cold front will surely cool things down in North Texas after more than 24 hours of summer-like conditions with some parts of the region feeling the heat in the low 90s. It will also usher in a new line of storms starting south in Goldthwaite through the Metroplex and north to Sherman, according to the latest weather service forecast.

“With good instability and decent shear in place, any storm which develops would have the potential to become severe with large hail being the primary threat,” the NWS forecast states. “Damaging wind gusts would be the secondary threat, with the better wind potential being in the evening when cell mergers and subsequent clusters or lines may contain bowing segments.”
