The Storm Prediction Center has upgraded our forecast area to a level 4 Moderate Risk for severe weather. All modes of severe weather will be possible, including a significant tornado threat. A Tornado Watch has already been posted for much of the forecast area. An eroding cap will give way to significant lift from an approaching dryline and large storm system lifting northeast onto the Central Plains from the Desert Southwest. Storms are already forming off the dryline and moving eastward just east of Abilene. A very moist atmosphere is in place across the area. There is 3000 to 4000 J/Kg for convective available potential energy (quite high) and moderate wind shear on the order of 300 M2/S2. Of real concern is backing surface winds across the area. All these parameters point to supercellular storm mode with any storm capable of producing large and strong tornadoes and giant sized hail up to softball/grapefruit size. In addition, heavy rainfall will be possible and some of the tornadoes could become rain wrapped and difficult to see. Residents of DFW should pay close attention to the changing weather conditions, and please take seriously any Tornado Warning issued for your area by taking appropriate action. Remember the best place to go is to an interior room, without windows, on the lowest level of the building or home.
