BLIZZARD '09

We will all be dead this time tomorrow.  There is a winter weather warning in effect for North Texas until 9pm CST. Merry Christmas!

Fancy words:

00z model guidance follows the trends of very aggressive 18z runs 
so have made some significant changes to current forecast. Have 
issued a Winter Storm Warning for northwest portions of North Texas with 
a Winter Weather Advisory a little farther south. See wswfwd for latest 
information. 


Powerful upper level storm system continues to be a little slower 
than previous model guidance indications with colder air now more 
likely to make it into North Texas before moisture pulls off to 
the east. All of the guidance indicates significant wrap around 
moisture coinciding with moderate lift in the 700-400mb layer... 
with saturation in the favorable area for snow production. 
Although indications are that instability is not quite as 
impressive above the strongest frontogenetic forcing as we would 
like it to be...snow is still likely. The combination of snow and 
strong winds will create near blizzard conditions at times...therefore 
warranting a warning. With air temperatures just above freezing and soil 
temperatures quite warm...accumulations are likely to be limited to areas 
where snow bands set up. 

NWS does not advise consuming pets and children for sustenance; however 
make sure you have plenty of steak sauce on hand.
