The above image shows the radar's estimate of total rainfall overnight, from the New Braunfels, TX radar. The medium to darker green shadings show widespread 1 inch totals, with 1.5-2 inches in the brighter yellow and orange areas between Austin and Houston. The maximum estimate by the radar is 2.78 inches, over portions of Lee and Fayette Counties (about 70 miles Northwest of Houston).
Much needed rain indeed, and without any significant severe weather, which is a good thing since this took place during the overnight hours.
Widespread precipitation has exited all but the far eastern and northeastern counties of Texas as of this writing, but now is when the winter weather event will begin to unfold across the South.
Below are the latest HPC forecasts of snow greater than 4 inches and freezing rain (ice) accumulation of at least one-quarter inch for today and tonight:
I'll make a more detailed post on the unfolding winter weather event around midday, after taking a closer look at the morning computer model runs. Generally, it appears that our thinking from yesterday is still on track.
