AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEMPHIS TN
1040 AM CST SAT DEC 15 2007

.UPDATE...
STRONG LOW PRESSURE SYSTEM CURRENTLY ACROSS THE ARKLAMISS REGION
WILL CONTINUE TO MOVE NORTHEAST TOWARDS THE AREA TODAY. AS A
RESULT...RAIN WILL CONTINUE TO MOVE EAST ACROSS THE AREA THROUGH
MUCH OF THE AFTERNOON. INSTABILITY IS REALLY LACKING SO HAVE
DECIDED TO PULL OUT THE MENTION OF THUNDERSTORMS EXCEPT FOR THE
FAR SOUTHEASTERN PORTIONS OF THE CWA. TEMPERATURES WILL NOT BUDGE
TOO MUCH TODAY WITH EXCEPTION OF EXTREME NORTHEAST MISSISSIPPI
WHERE TEMPERATURES WILL BEGIN TO FALL ONCE THE SURFACE LOW MOVES
NORTH.

THE HEAVIEST RAIN HAS ENDED ACROSS EXTREME NORTHWESTERN SECTIONS
OF THE AREA BUT AS THE UPPER LEVEL LOW APPROACHES THE
AREA...ANOTHER ROUND OF PRECIP IS LIKELY. FOR LATE THIS AFTERNOON
AND EVENING...WITH COLD AIR IN PLACE ACROSS NORTHEAST
ARKANSAS...THE MISSOURI BOOTHEEL...AND NORTHWEST TENNESSEE...A
MIXTURE OF RAIN AND SNOW THEN A CHANGE OVER TO ALL SNOW AFTER
SUNSET LOOKS TO BE THE SET UP AS THE UPPER LOW MOVE ACROSS THE
AREA.

&&

.PREV DISCUSSION... /ISSUED 350 AM CST SAT DEC 15 2007/

DISCUSSION...
NORTHERN PORTIONS OF THE MIDSOUTH WILL LIKELY EXPERIENCE A BRUSH
OF LIGHT WINTER PRECIP THIS AFTERNOON THIS EVENING. SOME BRIEF
PERIODS OF LIGHT SNOW OR FLURRIES POSSIBLE IN THE MEMPHIS METRO
THIS EVENING...AFTER A COLD AND RAINY DAY. OVERALL...FEW CHANGES
FROM EARLIER FORECASTS.

EARLY MORNING REGIONAL RADAR COMPOSITE SHOWED WIDESPREAD RAIN
EXTENDING FROM EAST TX...THROUGH AR...INTO THE OH RIVER VALLEY.
THIS RAIN WAS OCCURRING AHEAD OF A VIGOROUS UPPER LEVEL TROF
LIFTING QUICKLY INTO THE TX PANHANDLE. A MOISTURE LADEN
SUBTROPICAL JET EXTENDED INTO THE MID MS RIVER VALLEY... AHEAD OF
THE UPPER LOW. SOME EMBEDDED THUNDERSTORMS WERE NOTED OVER TX AND
WESTERN AR...WITH GREATEST LIGHTNING DENSITY OVER EAST TX. 00Z FTW
SOUNDING INDICATED SLIGHT INSTABILITY AT 850 MB...LIKELY FEEDING
ELEVATED THUNDERSTORMS OCCURRING CURRENTLY OVER TX AND AR.

CLOSER TO HOME... SOME BRIGHT BANDING WAS RESULTING IN ELEVATED
REFLECTIVITIES TO THE NORTH AND WEST OF MEMPHIS. 09Z SURFACE
OBSERVATIONS SHOWED KNQA RADAR OVERESTIMATING PRECIP BY A FACTOR
OF AROUND 1.3 TO 1.8...BASED ON NORTHEAST AR SURFACE OBSERVATIONS.
THERE WAS SOME CONCERN EARLIER THIS MORNING ABOUT SLEET NORTH OF A
JONESBORO TO DYERSBURG TO PARIS LINE. HOWEVER... DEWPOINTS HAVE
WARMED TO SEVERAL DEGREES ABOVE FREEZING IN THESE AREAS AND A
SHORTWAVE THAT ENHANCED DEEP LAYER LIFT APPEARS TO HAVE LIFTED OFF
TO THE EAST. THIS HAS LEAD TO MORE STRATIFORM PRECIP AND REDUCED
SHORT TERM SLEET POTENTIAL.

PRIMARY FORECAST CONCERN REMAINS SNOW POTENTIAL LATE THIS
AFTERNOON AND EVENING OVER NORTHEAST AR...THE MO BOOTHEEL AND
NORTHWEST TN. AS MENTIONED IN EARLIER DISCUSSIONS...THE BULK OF
SYNOPTIC SCALE LIFT WILL SHIFT EAST OF THE MS RIVER BY 00Z AND LIKELY
EAST OF THE MIDSOUTH ALTOGETHER BY 03Z. STILL SOME TRAILING LIFT
WITH THE PASSAGE OF THE UPPER TROF AXIS FROM LATE AFTERNOON INTO
MID EVENING...WHICH WILL DRIVE SNOW CHANCES OVER THE NORTHERN
FORECAST ZONES.

GFS AND NAM PROGGED QPF REMAINS ON THE LIGHT SIDE IN THE 6 PM TO
MIDNIGHT CST TIME PERIOD...RANGING FROM 0.10 INCHES LIQUID OVER
NORTHWEST TN AND NORTHEAST MS...TO AROUND 0.01 INCH ELSEWHERE. IT
APPEARS MAXIMUM SNOW ACCUMULATIONS OF 1 INCH OR LESS WILL OCCUR
FROM NORTHEAST AR...INTO THE MO BOOTHEEL AND NORTHWEST TN. WILL
THUS REFRAIN FROM ISSUING A SNOW ADVISORY AT THIS TIME. A SPECIAL
WEATHER STATEMENT WILL BE ISSUED BY 6 AM.

THE UPPER PATTERN REMAINS PROGRESSIVE THROUGH THE UPCOMING WEEK...
WITH A WEAK UPPER LEVEL TROF PASSAGE AROUND MIDWEEK. THE GFS PROGS
A STRONGER UPPER LEVEL TROF DIVING INTO TX NEXT SATURDAY. SOME
LARGER RUN TO RUN VARIATIONS HAVE BEGUN TO APPEAR IN THE GFS AND
THE ECMWF IS SLOWER WITH THE LATE WEEK PATTERN. THERE IS THUS
SOME FORECAST UNCERTAINTIES IN THE LATTER HALF OF NEXT WEEK.
