Yea maybe, just maybe if when the disturbance drops down south over us if we can get some wrap around moisture, we could see some snow flakes.

[weatherguy425]

Is it still coming down swmmom?

[jeff]

Likely seeing accumulation in Madison and Houston Counties. Brenham reporting mix...may see mix as far south as SE Montgomery and N Liberty Co...if rain can hang on a few more hours. 1-2 slushy inches looks likely in the advisory area.

8.7 inches at DFW now...incredible

[wxdata]

Observation out of the Ft. Worth NWS

"Looking at latest water vapor imagery/upper lvl pv analysis, a secondary shortwave trough is digging into the backside of the trough causing widespread precipitation over north tx atm. While this may not mean much... we are watching this feature very closely as it has produced 2 lightning strikes in west texas. The moisture is a little better out there and it's quite a bit warmer so it may have little to no impact on our local wx pattern in north tx... however we will be watching this feature closely for any potential for regenerating wintry precipitation for friday morning."

Report: Sleet in Copperfield

Freezing rain in Huntsville.

Report: Sleet in Copperfield

Yep!

[polisciaggie]

Well it's just raining now in College Station. There are some nice accumulations on vehicles but minimal ground accumulations. The sidewalks are all slushy now. I've heard a few ambulances go by already, hopefully it wasn't for wrecks.

[sleetstorm]

swmmom, how fast did all of the rain change over to wet snow & how fast did they grow to their large size?

[sleetstorm]

Report: Sleet in Copperfield

Where is Copperfield, srainhoutx?

Yep!

Yes! The flakes got smaller for about 10 minutes and now they are back to being huge. It has not stopped snowing since about 8 pm and if I understand the forecast it is suppose to keep snowing until 2-3 am. I can only imagine how much might be on the ground by morning. I hope my son gets a day off from school or either a late start. I am in heaven. I tried to take some pictures but it was my son's camera and I could not figure out how to get the flash on so the pictures did not come out very good. I will take some in the morning and post them if they turn out good.

It is about 9:25 now and shows no signs of letting up. The temp has fallen to around 32. And I thought the December 2008 snow storm was all I would ever get to see again.

I hope everyone who wants the snow gets some. It is so pretty!!!!

Is that good for those who want to get sleet/snow particularly in SE Texas, wxdata?

[srainhoutx]

NW Harris County sleet storm. About an 20/80 mix with rain being the highest. Gusty wind switch to NNE as well.

[C2G]

Appears some precip is developing to the west and southwest of the Houston area.

I had started sleeting really hard for about 30 minutes and then the next thing I knew my son had come in from swim practice at ATM and told me it was snowing. I went outside and the flakes were bigger than quarters. Could barely seen down the street. We are fixing to go back outside and see what is going on and I will report back.

So, I guess in answer to your question, it changed immediately from the heavy sleet to the big snowflakes. All the roadways are covered in pristine white as well as the rooftops, trees, sidewalks, anything outside.

Absolutely beautiful!!!!!

Here a water vapor sat of the new area of interest now swinging through west Texas

[biggerbyte]

Up to 1 inch accumulation in Porter possible tonight.

What? Say it ain't so...

[C2G]

Which way will that new area of concern trek, wxdata?
Do you believe it could trigger some energy for us?

This may dig further south, however it is a weak piece of energy.
