For background, see posting below.

The image is of the Storm Prediction Center's "Significant Tornado Index." What it shows is, given a strong thunderstorm, where tornadoes might occur. 

A value of "1" is worth watching and 2 or above means to pay attention if thunderstorms develop in your area. This map shows the index's value as of 3pm CDT. 

AccuWeather regional radar shows thunderstorms slowly continuing to build across the area, especially around (at 3:30pm) Stillwell and Cherry Tree, Oklahoma.

I believe DFW will receive 1-3" with heavier amounts as you go northeast. I-30 will become a mess for its entire route.  --- original forecast still valid --- Here are the latest NWS winter weather warnings and watches as of 3:15pm Note: the white "hole" in southwest Texas will be filled in with a purple winter weather advisory for 1-3 inches of snow.  Color codes: Pink = winter storm warning  Dark green = winter storm watch Purple = winter weather advisory  Bright green = ongoing flood warning  Dark blue and bright turquoise = freeze warnings.  As expected, t...
