The above image shows a broken line of thunderstorms, some severe, extending from South of San Angelo to just West of the DFW Metroplex, to the Red River North of the Metroplex. The line itself is moving slowly Eastward, while individual storms within the line are moving Northeast at 35 to 40 mph.
The most intense thunderstorm within the line is currently located just West of Ft. Worth, over Parker County, as show by this image from the Ft. Worth area doppler radar:
This storm is moving Northeast at 40 mph, and will pass just to the North of Ft. Worth (proper) during the next half hour to hour.
After remaining nearly stationary for the last few hours, the broken line of storms is finally beginning to make a move toward the East, as upper level energy increases from the Southwest.
With the above trends in mind, the DFW Metroplex can expect thunderstorm activity from now through Midnight. Areas South of the Metroplex, toward Waco and Temple, can expect activity toward the Midnight to 2am timeframe, and areas further south, toward the Austin-San Antonio corridor along I-35, can expect a chance of thunderstorms after 2 or 3 am.
The further Southward you travel, the lesser the chance of widespread thunderstorm activity.
The strongest thunderstorms overnight can be expected to produce hail and gusty winds to severe limits, and perhaps an isolated tornado (especially in Northern portions of the region).
