Yeah, I see it. Don't think it is yet. mPing reports are still blank, just one report in Corpus of drizzle.

Temps won’t warm much at all if that precip verifies

Yep Ive noticed also models are coming in more potent with Thursdays system,maybe another decent round of snow?Good news is since this system is coming with the upper level trough the setup looks like it could be maybe an all snow event,as the 540 line is much further to the south.

Wouldn't it be funny, if, after all this, it was the Thursday system that finally gave us the convective banding of snow we all hoped for on Sunday night?

The latest HRRR run highlights the uncertainty with respect to the rain/freezing rain line across the region with the W/NW half of Harris County receiving freezing rain while the E/SE half of the county receives rain. Unfortunately, all of the latest mesoscale models depict some type of freezing rain/sleet near or over the Metro area at this time.
