.DISCUSSION...
/344 AM CST SUN DEC 28 2008/

A QUIET WX REGIME WILL TAKE HOLD OVER THE AREA OVER THE NEXT FEW
DAYS...WHICH WILL BE IN STARK CONTRAST TO WHAT WE HAVE SEEN OVER THE
PAST COUPLE OF WEEKS...ESPECIALLY YESTERDAY WHERE SEVERE STORMS...
HIGH GRADIENT WINDS...WINTRY WX...AND FLOODING ALL IMPACTED THE AREA
ON THE SAME DAY. THE MODELS ALL AGREE THAT A TRANSITION TO A ZONAL
FLOW AT H500 WILL TAKE PLACE WITHIN THE NEXT 24HRS...WHEREBY THE
MAIN JET WILL SHIFT TO JUST N OF THE FA...RESULTING IN DRY WX WITH
GENERALLY ABOVE NORMAL TEMPS. THIS PATTERN SHOULD HOLD FIRM THRU AT
LEAST MID WEEK. AT THE SFC...A HI PRES CENTER WILL PASS TO OUR S...
RESUMING A SWLY FLOW TODAY...AND THIS WILL CONTINUE THRU MONDAY
MORNING WITH A WEAK RIDGE PASSING THRU LATE MONDAY AND EARLY MONDAY
NIGHT.  A WRMFNT WILL THEN PUSH THRU EARLY TUESDAY MORNING WITH A
CDFNT LATE TUESDAY.

OPPORTUNITIES FOR PCPN WILL BE RATHER SPARSE DURING THIS PERIOD WITH
DRY AIR PERSISTING THRU THE COLUMN AND NO SYSTEMS UPSTAIRS TO CREATE
LIFT TO ATTEMPT SATURATION. THE FRONTAL SYSTEMS TO MOVE THRU ON
TUESDAY WILL HAVE SOME LIFT ASSOCIATED WITH THEM...BUT MOISTURE NOT
ENOUGH YET TO RESULT IN PCPN. BUT THIS WILL BE ONE PERIOD TO WATCH
IF AN ADDITIONAL MOISTURE SOURCE IS TAPPED.

OTHERWISE...LOOK FOR ABOVE NORMAL TEMPS TO CONTINUE...CULMINATING
WITH STRONG SWLY GRADIENT WINDS ON TUESDAY IN THE WARM SECTOR WHERE
TEMPS MAY TOP 60F.
