CURRENT MODEL RUNS HAVE BEEN FAIRLY CONSISTENT WITH THIS

Perhaps this reasoning is being shared by the NWSFO Norman office and, thus, they have shown their precip maps accordingly?

Correct me if I'm wrong, there seems to be two separate areas of good precip. One tracking on the NM\TX border in the south plains and the other going from San Angelo to DFW southwards. I would assume Lubbock is more focused on their batch.

Look what the 12z GFS throws out next Tuesday/Wednesday...

Hey, we can dream cant we?

Johnny · #2466 Postby **Johnny** » Mon Dec 28, 2009 12:26 pm

I've got a question. If you were to set up camp somewhere to see the highest totals, where would that be?

Correct

If you glance at the 12Z GGEM you'll notice an Upper Level Feature tacking along N MX/ NW TX and attending surface reflection a bit further S and W in Northern MX.

Could you explain more of what this means? I'm not so smart =P

Blah not sure I get this, but alright

.UPDATE...
HAVE SLOWED DOWN THE SYSTEM...WITH NO PRECIP EXPECTED IN NORTH
TEXAS BEFORE 6 AM AND NONE IN THE METROPLEX BEFORE NOON. GFS/NAM
SHOW GOOD AGREEMENT...AND WANTED TO GET THIS INFO OUT NOW. WILL
LIKELY ISSUE WINTER WEATHER ADVISORY BEFORE AFTERNOON PACKAGE AS
SNOW AMOUNTS LOOK LIKE 1-2 INCHES IN THE WEST AND LESS THAN ONE
ACROSS METROPLEX AND SOUTHEAST HALF OF NORTH TEXAS. UPDATE OUT
SHORTLY.,.WITH REST OF GRIDS UPDATED/ADJUSTED FOR THE AFTERNOON
PACKAGE. 84

Wouldn't slowing down the system up the totals? Just curious.

Not much time for me, but basically the GGEM suggests three features. Upper Level Disturance track ENE out of New Mexico, surface reflection further SW in Northern Mexico tracking E across Northern MX into Central TX and a developing coastal low...

Thanks, I guess that explains the different areas of heavy precip.

Does the 12Z European show snow for Dallas around Sunday, January 3? I have plans to attend the Dallas Cowboys game and wanted to get a feel for travel conditions Saturday and Sunday as I will be driving.

Hour 144 appears to show the freezing line to the South of DFW. However, what is not clear to me is whether there is precipitation occurring at the time:

That would be dry and cold. There's a high pressure over Texas which will keep moisture away. Assuming of course it verifies.

Is it just me or does it seem like the local NWS offices are starting to write this storm off?

NWS FTW needs more people I disagree with.

#2477 Postby **HockeyTx82** » Mon Dec 28, 2009 2:45 pm

Does this storm look anything like the first storm that hit our area earlier in the month. The one that came out of Mexico, (did not have much data on), hit El Paso, (notice the WST our for that area) and then swung up here and gave us snow? Just throwing that out there based off what I remember and nothing more. Any thoughts?

#2478 Postby **Portastorm** » Mon Dec 28, 2009 3:09 pm

Here's how desperate I am ... the 18z NAM is getting my hopes up! :lol:

This run has more cold air it appears and a wider precip shield over the state, or so it seems.

#2479 Postby **Ntxw** » Mon Dec 28, 2009 3:17 pm

Models are starting to trend stronger with this storm as many of us have stated. It's getting closer and data is getting better. Lets see how it pans out. And this is somewhat different Hockey no two storms are the same. This one has more cold air to work with. So rather than the back wrap around snow\moisture, the main shield that gave constant rain in the storm earlier in the month would rather be frozen precip. This is what gave W Falls and Okc heavy snow last week. Convection in the warm sector (heavy rain and thunderstorms) drove in to the cold air and just dumped snow.
