Travis update...

We've got several hours of sleet before we ever get to snow, and it could be heavy sleet (and snow) at times.

This movie shows raw computer model data, and it continues to show significant sleet falling befor the transtion to snow occurs after midnight.

Why will it be sleeting when the temperatures are in the 20s at ground level?

Airplane data confirms that there is a significant layer of air above freezing (as warm as 45 degrees) between 5,000 and 10,000 feet above ground (roughly 1-2 miles up). Everything else in the atmosphere above and below that layer is freezing or colder. But that layer is warm enough to melt all the snow. It is then refreezing as sleet (ice pellets) befor reaching the ground.

So while I do think we'll eventually change over to snow (between 1am-4am for Houston), first comes the sleet, and lots of it. We'll wake up to a winter wonderland, but it may be more icy than snowy.

Also, if you look carefully at this computer model around 9am, it is showing "lake effect" snow downwind from Lake Livingston and "ocean effect" snow offshore from Galveston! That's what happens when arctic air blows over long stretches of warmer water. The turbulent flow it creates can generate snow showers!

Remember, temperatures will drop into the teens by morning and barely warm back into the 20s. Factor in those northwest winds at 15-25 mph and it's going to feel like its in the single digits all day long! Stay warm, friends!

We'll continue to guide you through this historic winter storm, and I'm confident we'll get through this together, come whay may.

32 and heavy rain...finally coming into my area

Some lightning with heavy snow, sleet showers west of Houston. Don’t be surprised if you hear a rumble of thunder or two, tonight!

Well I hope those whiney Dallas ppl on 2k are happy now

They got their snow.

Heavy freezing rain and a little bit of sleet in Rosharon right now

Looks like a decent area of precip is about to move into metro Houston.

West of Houston in Katy/Cinco and its moderate to heavy sleet. It’s so loud! This is awesome.

Feeling better about getting 5 plus inches up here. That snow shield approaching SA/Austin is going to intensify here with the gulf and unload.

Oh, I’m not going to bed. I got a heat lamp attached to the Ranger and will go driving through it. Up all night baby!

I hope so. All the discussion of that stout warm nose has me concerned.

I bribed him.

Actually, I just think he's busy. It's a lot of work to post on both boards. I know...

I’m Cantore on steroids. My first severe Winter memory was the 1989 December storm. I was 7. 70 and thunderstorms then temp dropped 45-50 degrees and had 6 hours of thunder sleet and thunder snow. It was wild.

I thought I’d never see it again but I went to grad school at Ohio State and saw it again.

I may again tonight.

Accumulating sleet, maybe light snow here. 26.2 at my house, kids are pretty excited yelling in the neighborhood haha
