Is the low over TX falling apart or strengthening?
Theoreticaly (i need huked on foniks), if it holds together as if moves farther east, would it not start to pick up gulf moisture? Wouldnt' that cause it to lay down more precip?

Got my Met degree from a cracker jack box, thus the questions.

Tim, the ULL is wrapping up ... (getting stronger)

SF, thanks. I wanted to say that it was, but wasn't sure. Do you think that it'll start to tap into gulf moisture and possibly cause more snow than forcast at the present time? NWS in Jackson is saying 1-3" in northern sections of MS and a dusting as far south as Mendenhall, which is about 30 miles north of me.
Where is it going to track? Will it track across central MS or what?
If the track is farther south than expected, would the southern part of the state have a chance to see snow too?

Its closing off at the mid levels. See the darker stream extending from the southwest to the east coast, thats the vort max, from there you can clearly see the low closing off across New Mexico.

I mentioned this in the Severe Weather Discussion thread Friday afternoon, too at 2:57 pm EST in regard to the strong to severe weather potential for central Florida, late Saturday and Saturday night:

Water Vapor Loop: Upper level low moves out of Arizona into New Mexico.....

A lot of deep moisture ahead of this upper level low, across the Gulf of Mexico and Texas.

Both you and SF are 100% right.

Tonight's ETA initial shows it best.



As the trough becomes negatively tilted, intensifying PVA ahead of the vort will cause strong UVM to develop, and a nice deformation zone should result, as the low closes off.

I wish that it would snow all the way to the coast in MS or Bama but that looks about impossible now .
