Texas Winter 2012-2013

[downsouthman1]

Still almost 46 degrees here in Austin. I'm skeptical it's going to get cold enough in the lower layers to keep anything frozen long enough to get to the ground...

Look for wet-bulb effect. It is important to note the dewpoint temps as temps generally will not go lower than that. In the Austin area, the dewpoints are between 29 & 32. So I would expect air temp will not drop below that tonight. http://www.wrh.noaa.gov/zoa/mwmap2.php?map=zfw

Snowing in San Angelo and already sticking!

Send us a pic or two, Ivanhater.

0z GFS is still hinting at some big changes. Would be a series of very strong fronts, heights in Alaska are very impressive. Canadian is just as wild with a big snowstorm first then 510 thickness (at least Feb 2011 cold) to the central plains on that run for the first arctic front.

Still long range though, we'll continue to track the trends. The models are quietly showing bigger highs per run. Not the 1050s yet but I expect they will as the resolution gets better in the closer range.

People must not be excited at all by tonight's storm, since there's so much discussion about 7-14-day Models.

Current storm is taking its sweet time, people are probably just waiting to see what happens outside their window

The models keep getting bigger with each run. Usually it's the other way around they show it then slowly back off. For instance 0z GFS has 580+dm ridge popping up in the Pacific compared to 12z which was 564-576.

It might be too warm for any frozen stuff to fall in the DFW area. Still hovering in the low 40's here.

Wet bulb. Dew point is at 31, temp at 43, which means when rain falls and the air saturates, the temp will drop and the dew point will rise to meet somewhere in between. Plus, soundings from DFW show that temperatures above the surface are plenty cold to support snow. They are just so dry at the moment, so it will be a while before anything reaches the ground.

Well, since I live in Killeen & we rarely get measurable snow/sleet, I'm interested in current storm. We have not had measurable frozen precip yet this year.

I hope so. I told Mrs. Gpsnowman to wake me up before she leaves for work if it is snowing. Wouldn't want to miss any winter. She thinks I am crazy.

I told my wife the exact same thing.

Need to get underneath those heavy bands of precip to get maximum cooling at the lower levels. The non-virga stuff is around San Angelo and Midland.



Edit: Wet bulb currently could probably get DFW to about 35. Austin about 36-38

Thats pretty funny downsouthman1. The winter "high" I would get would make up for lack of sleep.

:uarrow: Thats pretty funny downsouthman1. The winter "high" I would get would make up for lack of sleep.

That's why I don't sleep during Winter Storms. Too much natural adrenaline.

Ntxw: I beg to differ. On my way home from work, stuff that barely showed up on Radar was actually reaching the ground as light rain down here.

0z Euro, nice to look at

Coming down hard in San Angelo right now!

That looks like some big flakes! I think it's time you build a Texas-sized snowman!

Edit: Still looks like another 1-2 hours of moderate to heavy snow in San Angelo. Temps about 30 so it will stick like glue

Coleman just west of Brownwood is reporting light snow. Should be seeing changeover from Abilene to the southwest counties of the Metroplex not long after

[Portastorm]

A quick check-in to report that at 1:40 am a mixture of light rain and sleet is falling at the Portastorm Weather Center.

[South Texas Storms]

It's sleeting here at my house on the NW side of SA!
