Ice beginning to glaze my car in Porter.

radar is quickly filling in in South Texas

http://radar.weather.gov/radar.php?rid= ... 1&loop=yes

Stairs have already iced over....as well as the railings. This reminds me of the ice storm in the late 1990s. Am anxious to see what happens overnight.

Hate to leave the party but I need sleep. Will listen for the next big system.

According to The Huntsville Item's Facebook post: All Huntsville schools will be closed tomorrow.

That will be an absolute nightmare!!! One has to think that deep convection will bring warm air down and keep us around or above freezing. If not, gonna be some major problems

I think evaporative cooling is helping to contradict this. On another note, heavy sleet here with a layer on the sidewalk and beginning to get on the roads and the party hasn't even started yet.

32 here in Beaumont light rain not sure why we do not have a warning in our area

Paul Baustista wrote:there will be no warming only cooling. this is a cold core upper level storm. with very cold air in the upper atmosphere. cold air from the cold core low will be eliminating any mid level warm layer.

Incorrect. I wish I had the images to show, but if you go to any model site and look at the 500mb-700mb temperatures, this is not a cold core system. There is a significant warm nose (inversion) above us which is exactly why the preicp falling tonight will NOT be snow. It falls as snow, gets in the warm layer, and depending on the depth of the inversion, will melt completely into rain drops then freeze on contact since the surface is at or below freezing and that is what we call freezing rain. If there is a short warm depth and then falls back below freezing a couple thousand feet up, then the precip will refreeze, thus creating sleet.

Tonight, there is a pretty good depth of warm layer where this will mainly be a freezing rain issue more than a sleet issue I believe. Though, due expect some sleet. I wish I had a Skew T to upload along with a 500mb-700mb diagram to show you, but I am not where I can upload that at the moment.

Paul Baustista wrote:wrong. this is a cold core upper level low pressure system with cold air at its core in the upper atmosphere. dont lecture me

No, he is right when saying there is warm air above. Look at how deep that warm layer is:

Alright, I lied, you gave me a challenge where I wanted to upload these.

This would be a cold core low (aka: what we could see next weekend according to the GFS) 500mb

This is what we have currently: 500mb


This is the current Skew T for the Houston area:

Follow the O'C line and notice the huge inversion. About 50 degrees up about 800mb. By looking at this sounding, this would be more of a freezing rain sounding than sleet, but sleet could still fall, which is obviously happening around some of the areas.

To me this one paints the picture more, nuby.

.

yes, I agree, I was just trying to give more perspectives. there is a lot of very interesting stuff happening

I tried to go to sleep but I can't, time to get some coffee this event looks to good to miss lol.

interested in the little cell merger in western harris. trying to waste a half hour to see what happens
