Wind fields will only strengthen later on. too bad we couldn't also get one from say Ft Hood/Killeen, Camp Mabry/Bergstrom in Austin, or New Braunfels at the NWS office. so see what's going on between the metroplex and Del Rio.

Chicago Storm Posted April 26, 2015 Share Posted April 26, 2015 The northern tor warned supercell approaching Throckmorton looks outflow dominant. Will be interesting to see what new development NW-SW of Abilene does. Link to comment Share on other sites More sharing options...
NTXYankee Posted April 26, 2015 Share Posted April 26, 2015 FWD stated in their AFD, sorry can't post that the surface low may be developing further north than what was originally thought and that the threat could shift more into the metroplex than central Texas. They also stated that the supercells off the low are still expected to form in the 5-10 pm timeframe, so what we are looking at right now is possibly not the bigger threat to come?

This is not the main show. The majority of the large-scale ascent is still over New Mexico right now and will not hit the warm sector in TX until 22-0Z. That round will have a higher threat of tornadoes as the LLJ ramps up and LCL's drop. Link to comment Share on other sites More sharing options...
