Steve McCauley update:
“ the upper-air disturbance that passed overhead was a little stronger than expected, that does not account for the enhanced snowfall we saw, especially in the western half of north Texas.
There was an unexpected jump in relative humidity overnight which prevented the snowflakes from sublimating (i.e., disappearing) and thus they were able to pile up significantly more than anticipated.
Had the humidity stayed low, this would not have happened.
So where did this added humidity come from? It appears some of it came from area lakes.
As many of you have noted in the comments, there also appears to have been a "lake effect" that enhanced the snow potential. On satellite imagery and radar you could see "cloud streamers" coming off all of north Texas lakes. Snow clouds even streamed into the Metroplex from as far away as Lake Texhoma!”
