Severe Thunderstorm Watch issued for north Texas

Severe Thunderstorm Watch has been issued for nearly all of North Texas, until 3:00pm today. A developing line of thunderstorms is approaching from the west, currently located from Mineral Wells through Wichita Falls. This line already has embedded severe thunderstorms, and will continue to gain intensity as it travels twards the DFW Metroplex. Today's primary risks are large hail and winds, the tornado threat today is very low and will likely not be an issue for our area. Timing on these storms, best guess i can make right now will be anywhere from 10:00am to noon for arrival in DFW.
