Texas Under Winter Storm Watches for Over 12 Inches of Snow

Texas is under a Winter Storm Watch for the December 20th storm (click here for this morning's discussion) as that area is expecting over 12 inches of snow. Here is what the models are saying:

6z GFS 84 Hour Snowfall Accumulation

The GFS is going in cautiously compared to the GFS, with maximum accumulations up to 15 inches, which is still a lot of snow. 

12z NAM 84-Hour Snowfall Accumulation

The 12z NAM is going in, guns blazing, with maximum snow accumulations projected at 21 inches- nearly 2 feet! The NAM has been known to be a little on the heavy side with snow accumulations, so we will be going with the GFS for now, until we see the new 12z GFS, which ought to be similar to the 6z GFS as we are getting into the short range part of forecasting.
This post was just a briefing, and if there is anything else we will notify you.
