GFS indicates plenty of cold air aloft from SE TX west to West Texas. However, surface temps in Houston may be above freezing with a small warm nose aloft. There may be a shallow layer of sub-freezing air around 1000-2000 ft above the surface during the precip. This could allow the melted snowflakes to refreeze into sleet for Houston.
Farther west, the cold air may be deeper in San Antonio & Austin with no warm nose and surface temps below freezing. You listening, Portastorm? Unfortunately, as I've stated before, WGLs typically produce precip in south Texas and along the coastal counties rather than way up north into the D-FW area. Moisture is generally too limited away from the Gulf.
Looks like I have some work to do on my wall prior to next Friday...

Nice post 57 but I have been having trouble viewing your images that you post and even your avatar for the last few days. Not sure if it is an error on my end.
That's been happening with mine as well.
