102 hours: looks a bit colder than 18z just by glancing at it.

Hour 90:

It's a bit slower with the cold air, but no big deal. Still a ways away. Like wxman said one time, how can you pick one model over the other? There is so much variability still that one run is just as good as another. I wait with bated breath for the 0z euro and gfs.

I think we're going to have some serious mixing issues when all this starts out--if it even happens. Anytime you get stratoform precipitation, it is indicative of warm air advection. Surface temps are going to play heck with the precip. On the flip side of the coin, the upper levels are forecast to ...

18z GFS is running. Will be in the timeframe of the possible winter storm in about 20 min.

GFS shows snow line as close as College Station for now.

Dan, that image is so pixilated. There is noway in heck you can tell where the snow line is or isn't. Again, I think it's too far out to call the shots at this point. I'm satisfied that the chance of wintry weather is real and not a 384 hour dream.

Dallas Thoughts: EYOND MONDAY...GLOBAL GUIDANCE DIVERGES MORE SIGNIFICANTLY. THE FAVORED ECMWF PINCHES OFF A PIECE OF EASTERN PACIFIC ENERGY...MERGES IT WITH THE TROF OVER THE WESTERN US AND CLOSES OFF AN UPPER LOW. THIS IS SIGNIFICANT BECAUSE THERE IS SOME FAIRLY COLD AIR ASSOCIATED WITH THIS FEATU...

There ya go, Wxman. Post away!

Jason, I think last summer has affected your ability to think properly. Your talking rubbish already! Another hot summer? Please tell me this is a joke. Am I on Candid Camera? nope, I love the sun and hot stuff. The more the better, thats why I live in Houston. The added benefit of last summers pat...

You guys should report the sleet to HGX via webmaster. I bet they don't have any idea.

Man, I just got home from work and the sleet was really coming down on I-45 at Woodlands Parkway! When I walked out of work, you could see the sleet bouncing all over the car and hear it hitting the trees and bushes. Very cool

Yesterday 18Z NAM @ hour 66...time sensitive... http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/namer/nam/18/images/nam_pcp_066l.gif True story. Sorry, I've been working very long and late hours so I'm only catching glimpses and pieces of what's going on here. I apologize for asking dumb questions.

Looks like more interesting wintry weather may be ahead for TX later next week. AO, NOA, (severely negative) and a rather robust +PNA ridge is suggested by the OP as more strongly suggested via the ensembles. A very strong late winter Arctic front will pass through TX Sunday/Monday ushering some ve...

The following discussion pertains to IAH - northern Houston. NAM has been trending warmer than the GFS in many areas, but apparently not in Houston. 18Z not all in, but 12Z forecasts quite warm air between the surface and 10,000ft (low 40s) until around 3am Friday. Beyond that, it shows significant...
