.PREV DISCUSSION... /ISSUED 220 AM CST SUN NOV 29 2009/

DISCUSSION...MAIN WEATHER STORY THROUGH THE FORECAST PERIOD WILL
CENTER ON SEVERAL LARGE TEMPERATURE SWINGS. DRY WEATHER WILL MORE
THAN LIKELY PREVAIL THROUGHOUT THE NEXT WEEK.

A COLD FRONT THAT SWEPT SOUTH ACROSS THE REGION LAST EVENING
CONTINUES TO RESULT IN RATHER BLUSTERY CONDITIONS EARLY THIS
MORNING. MANY LOCATIONS HAVE BEEN SEEING NORTH WINDS AT 15 TO
20 MPH THROUGH THE OVERNIGHT HOURS. THESE COOL WINDS WILL CONTINUE
THROUGH THIS AFTERNOON MAKING IT FEEL NOTICEABLY COLDER.
HOWEVER...DESPITE THE COLDER AIR MASS IN PLACE
TODAY...TEMPERATURES WILL STILL BE SEVERAL DEGREES ABOVE NORMAL
WITH HIGHS IN THE MID 40S.

PRESSURE GRADIENT WEAKENS BY THIS EVENING AND EXPECT WINDS WILL
QUICKLY DIE OFF BY AROUND SUNSET. SFC HIGH WILL CONTINUE TO SLIP
FURTHER SOUTH TONIGHT AND A LIGHT WEST DOWNSLOPING WIND WILL
DEVELOP AND PERSIST THROUGH MONDAY INTO THE FIRST HALF OF TUESDAY.
UPPER LEVEL RIDGING AND INCREASING TEMPERATURES ALOFT ON MONDAY IN
COMBINATION WITH THE WESTERLY SFC WINDS...WILL ALL SUPPORT GOOD
WARMING WITH MONDAY HIGHS WELL INTO THE 50S TO MAYBE EVEN A FEW
60S ACROSS SOUTHWEST ZONES.

THE NEXT CLIPPER SYSTEM WILL TRACK FROM CANADA ON TUESDAY INTO THE
GREAT LAKES REGION BY TUESDAY NIGHT. THIS WILL BE TOO FAR REMOVED
FOR OUR AREA TO SEE ANY PRECIPITATION...BUT A MODEST COLD FRONT WILL BE
PUSHED SOUTH ACROSS OUR CWA. THE COLD FRONT SHOULD COME THROUGH
SOMETIME ON TUESDAY...BUT EXPECT WE WILL BE ABLE TO SQUEEZE OUT
ONE LAST NICE DAY WITH TUESDAY HIGHS ONCE AGAIN IN THE 50S TO
AROUND 60. THE COLD AIR WILL BEGIN TO GRADUALLY WORK INTO THE
AREA ON WEDNESDAY WITH HIGHS LIKELY ONLY IN THE 30S TO AROUND 40.
THE ECMWF SHOWS THE BRUNT OF THE COLD AIR MOVING IN ON THURSDAY
AND FRIDAY WITH 850MB TEMPERATURES RANGING FROM -8 TO -11 TO END
THE WORK WEEK. THIS WOULD TRANSLATE IN SFC TEMPERATURES THAT
STRUGGLE TO RISE INTO THE LOWER 30S FOR AFTERNOON HIGHS...WHILE
MORNING LOWS FALL INTO THE TEENS. THE FORECAST MODELS THEN BECOME
RATHER VARIABLE AS WE LOOK AHEAD TO NEXT WEEKEND WITH A WIDE
ENVELOPE OF POSSIBLE SOLUTIONS.
