Texas weather seems to only be marginally accurate out to 6 hours, beyond that its anyone guess it would seem. Today's storms did not materialize as anticipated during the day, however a retreating cold front and approaching trough mean round two of severe weather potential is upon us! A cluster of severe thunderstorms has already developed south of DFW, building twards the NNE. The storms are expected to continue growth for the next few hours and appear likely to affect most of the DFW metroplex overnight tonight. Large hail is the primary risk, but tornadoes cannot be ruled out. As I write this, a radar indicated tornado just developed 20 miles NW of Waco, so anything seems possible tonight!
