Mean mid-level RH is high right now (about 90%) on DFW 0z upper-air observation data this evening. But low-level is below 50%. Moisture is there overall. But, latest 0z NAM data coming in tonight still is not showing much omega/lift aloft overnight around DFW, and absent by morning (before column really dries out by midday). GFS hasn't been showing much lift either. Just FYI.

Lift has looked like it will be better across E TX into N LA. This evenings flurries and dusting is just bonus, few hours before good stuff gets here.

Sleet, reported in Houston on 8 pm NWS observation data.

Not many flakes but what is falling is perfect little stars.

Been very windy here near the coastal bend/mid-coast region since early this evening (gusts up to 50 mph) with the surface Gulf low apparently not far offshore right now. I don't remember where it was this windy in an overrunning Arctic airmass scenario with frozen precip involved. But this could increase the power outage risk overnight - this morning (Tuesday). Especially if any icing from freezing rain/drizzle happens on trees & power lines at the same time.

GFS, Euro and NAM all intent now on the sleet line getting all the way down, close to Brownsville later this morning after sunrise. I'm really hoping I can cash in on all sleet/ice pellet event like in the 2021 TX chill.

I'm going to be shocked if New Orleans gets any kind of snow accumulation later today. GFS, Euro and NAM all showing that now..
