Interesting, as I just noticed that the models (GFS, NAM, and NAM 3k) were suggesting that a complex of vigorous storms (possibly supercells transitioning to an MCS?) may form in the vicinity of the DFW metroplex tomorrow (especially in areas S/SW). I would place my bet on a slight risk if the models continue to suggest the formation of a storm complex.
EDIT: SPC 6z outlook confirms slight risk (5% tornado/15% hail) for north central Texas, including the southern portion of the DFW metroplex. NAM and GFS place the warm front slightly further north (into Denton and Collin counties) so if this holds I wouldn't be surprised to see the slight risk adjusted northwards, though the NAM 3k places it on a line from downtown Fort Worth to north of downtown Dallas (resolution differences?). If the warm front moves further north (as NAM and GFS suggest) I'd expect the bulk of the DFW area to get in more on the storm action.
