Possible Christmas Snow Storm – Friday Evening Update

Highlights Confidence in a Cold Air Outbreak in Texas by Christmas Afternoon is high Confidence in light snow occurring in Texas is moderate. Confidence WHERE in Texas snow will fall is low. Confidence in accumulating snowfall in Texas is low. We will begin to get better weather model consistency on Saturday, at least that is the hope.

Worth yesterday evening.  In it, they break down the processes that would need to be in place with this next system for snow to develop.  It’s very interesting and not extremely nerdy.  I did include some definitions in parenthesis where appropriate.  It’s...
