.DISCUSSION...
TORNADO WATCH 556 CONTINUES UNTIL 7AM WITH PERHAPS MORE PERAHPS TO
COME TODAY WITH HEATING. AREA RADARS HAVE BEEN FAIRLY QUIET FOR
THE WEE HOURS...BUT THERE IS SOME IMPRESSIVE DEVELOPMENT OVER THE
LAST HOUR KNOCKING ON OUR DOOR NOW IN NE TX AND SE OK. IN FACT...WE
WILL UPDATE THE ZONES TO LIKELY FOR THESE AREAS IN THE NEXT FEW
MINUTES. THE WATER VAPOR SHOWS THE UPPER LOW CORE IS CURLING UP
OVER N OK INTO S KN AND ON THE SURFACE...THE DRY LINE OUT IS
NUDGING INTO THE DFW METRO PLEX. OTHERWISE...WE ARE MUGGY WITH
TEMPS AND DEW POINTS IN THE 60S. SURFACE WINDS ARE S/SE WITH SOME
GUSTS AND THAT SHOULD CONTINUE FOR MUCH OF THE DAY...JUST BELOW
LAKE WIND CRITERIA FOR THE MOST PART.

WE WILL BE NEAR RECORD WARM TERRITORY FOR A RUN OF MAINLY
AFTERNOONS HERE INCLUDING CHRISTMAS DAY FOR MOST OF OUR AREA
ALONG AND SOUTH OF I-20 AND THEN AREAWIDE FOR SATURDAY AHEAD OF
THE BOWLING BALL CLOSED LOW. THE LONG RANGE MODELS ARE A LITTLE
CLOSER NOW IN AGREEMENT...BUT GFS IS STILL A LITTLE FASTER THAN
EURO WITH A SIMILAR PRESSURES AROUND 539DM. THE GFS IS SOUTH OF
DENISON DAM AND EURO STILL JUST EAST OF MIDLAND TX FOR MONDAY 12Z.

THE WPC 5 DAY TOTAL QPF SHOWS MOST OF OUR AREA IN A 1 TO 3 INCH
RANGE WITH SOME 3 TO 5 EXTREME NORTH. SO WHILE A LATE WEEKEND
FLOOD WATCH FOR RAIN MAY BE ONLY UP THERE...OUR RIVERS AREA WIDE
ALL FLOW DOWN HILL AS WE LOOK WRAP UP 2015 AND HEAD INTO THE NEW
YEAR. /24/
