Question....is the rain/moisture we're getting now helping to cool the warm layer in the upper atmosphere? Is the rain we're getting now helping any at all?

Thanks Mr T. That's the one--heading right through the heart of Houston!

Numerous reports of sleet, graupel and freezing rain coming in across Northern Harris County.

Well the evaporation that is occurring in the area is an endothermic process meaning it is cooling the atmosphere. That is what we commonly associate with the wetbulb temp. Now what does happen with stronger storms is the precip can actually bring warmer temps down to the surface. Something we will need to keep an eye on as we go into the night but I suspect this won't be much of an issue.

Ice coating car tops and metal surfaces in NW Harris County.

[Mr. T]

Officially freezing rain in Kingwood with a temp of 31. A nice glaze on exposed surfaces, cars, etc...

[Charlster]

I live in Angleton. Can we expect any ice down this far? I wasn't expecting this weather at all.

Got it...thank you

I'm on the north side of Kwood literally right next to Kingwood Park High.

Officially 32 at IAH with freezing rain and thunder

[jasons2k]

Starting to ice over here. When it first started, the water was running down the windshield and the car tops were wet. After that burst of sleet (maybe graupel) it's all freezing-up now. Plants also getting a coat of ice now.

Well that's not every day that happens around here, let alone in March. Maybe next winter we'll get a blizzard.

Gotcha.ya its starting to freeze here on the car now

Update from Jeff:

This is going to be a significant winter weather event!

Corridor of strong convection with P-type mix between sleet and freezing rain developing roughly along and north of I-10 from San Antonio to Beaumont.

Freezing rain and sleet with accumulation rates of .05 to .10 of an inch an hour will be possible in the outlined region on the graphic below through 300am. Models have not handled the onset of this precipitation well and expected longer duration of freezing rain/sleet mix with heavy freezing rain possible in convective cells.

Already numerous reports of ice and sleet accumulation over Waller, NW Harris and Montgomery Counties with surface air temperatures of 30-32. Crusty accumulation of freezing rain and sleet is likely over all of the warning area. Do not think onset of more sleet will cut down on accumulation amounts at all given the amount of lift and moisture we are dealing with.

TXDOT is showing widespread ice formation on bridges and overpasses over Burleson County from west of College Station to Somerville to Dime Box.

Ice starting to form on top of my parking garage here at 59 and weslayn

[txsnowmaker]

After reading Jeff's latest update, I am wondering if we may see an Ice Storm Warning issued for Houston before all is said and done.

ice forming here also
