.PREV DISCUSSION... /ISSUED 225 AM CST MON NOV 30 2009/ 
OVERNIGHT LOWS TONIGHT COULD RETURN TO THE FREEZING MARK THX IN PART 
TO THE XPCTED COLD AIR ADVECTION.

WEAK HIGH PRESSURE LOOKS TO AFFECT WX CONDITIONS ACROSS THE REGION 
ON TUE WITH CLR SKIES AND MILD TEMPS XPCTED. THE FOCUS THEN TURNS 
TOWARD THE WRN GULF TUE NT AS A LOW PRESSURE SYSTEM DEVELOPS AND 
BEGINS TO TURN TOWARD THE NE. THE LATEST MODEL SUITES ARE STILL 
FAIRLY CONSISTENT WITH TRACKING THE SFC LOW TOWARD NRN AL EARLY 
WED...AND THEN TAKING IT ACROSS THE ERN HALF OF THE AREA LATE WED 
AND INTO THE NE STATES THU. WIDESPREAD AMOUNTS OF LIGHT TO MOD 
RAIN/SHOWERS SHOULD ACCOMPANY THE LOW PRESSURE BEFORE A TRAILING 
COLD FRONT MOVES THROUGH THE REGION ON THU. THE LATEST RUN OF THE 
GFS CONTINUES TO INDICATE QUITE A BIT OF COLD AIR ADVECTION BEHIND 
THE FRONT MOVING INTO THE AREA ON THU WITH OVERNIGHT LOWS THU NIGHT 
FALLING BELOW 30 DEGREES.

A STRONGER AND MORE EXPANSIVE AREA OF HIGH PRESSURE COUPLED WITH MOD 
POLAR AIR THEN LOOKS TO SETTLE INTO THE SE REGION ON FRI AND SAT. AS 
SUCH...OVERALL TEMPS FOR NEXT WEEKEND LOOK TO RUN SLIGHTLY BELOW 
NORMAL BASED ON THE LATEST MEX GUIDANCE.
