.PREV DISCUSSION... /ISSUED 348 AM CST TUE DEC 15 2009/ 

DISCUSSION...
LOOKS LIKE WE ARE IN FOR A COLD DAY TODAY,  WENT WITH THE
COLDER MET NUMBERS AS THEY WERE IN MORE AGREEMENT WITH WHAT
THE ECMWF WOULD INDICATE.  ALSO WENT BELOW THE MAV TONIGHT
AS SKIES WILL BE CLEAR AND WINDS LIGHT.  

WARMER WEATHER IS IN STORE FOR WEDNESDAY AFTERNOON AND
THURSDAY BEFORE THE NEXT SHOT OF COLD AIR PUSHES INTO THE
AREA FRIDAY AND FRIDAY NIGHT.  COULD BE SOME PRECIPITATION
WITH AND BEHIND THE FRONT BUT ONLY WENT WITH SLIGHT CHANCE
POPS.  DID MENTION SNOW BUT IF IT DID SNOW IT WOULD NOT
AMOUNT TO MUCH.

SUNDAY AND MONDAY WILL BE DRY. THE ECMWF SHOWS ANOTHER 
SURGE OF COLD AIR WHILE THE GFS IS WARMER.  AT THIS TIME
DID A COMPROMISE WITH THE TEMPERATURES IN THAT TIME RANGE
WHICH WOULD HINT THE THE ECMWF IS RIGHT.
