SOUTHWESTERN COPIAH...NORTHWESTERN LINCOLN AND SOUTHEASTERN JEFFERSON
COUNTIES...

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
959 AM CST FRI NOV 28 2008

.DISCUSSION...SURFACE WEATHER ANALYSIS THIS MORNING CONTINUES TO SHOW
A RATHER PERSISTENT BAND OF MODERATE TO HEAVY RAINFALL OVER THE
CENTRAL PART OF THE JAN CWA. A FRONTAL BOUNDARY IS SLOWLY PROPAGATING
TO THE SOUTH...AND IS EXPECTED TO STALL OVER THE SOUTHERN HALF OF THE
CWA THIS AFTERNOON. THIS...IN CONJUNCTION WITH LOWER AND MIDDLE 60S
DEWPOINTS...WILL SERVE AS A FOCUSING MECHANISM FOR MORE SIGNIFICANT
RAINFALL THROUGH TODAY AND TONIGHT. THE MAIN CONCERN WILL BE TRAINING
OF HEAVY RAIN ALONG AND JUST SOUTH OF INTERSTATE 20...WITH WIDESPREAD
PONDING OF WATER AND EVEN SOME MINOR LOCALIZED FLOODING OF POOR
DRAINAGE AREAS. EXPECT THIS BAND OF RAIN TO MOVE SLOWLY TO THE NORTH
LATER TODAY AS A DEVELOPING AREA OF LOW PRESSURE APPROACHES FROM TX.

A FEW CHANGES WERE WARRANTED IN THE FORECAST GRIDS THIS MORNING BASED
ON CURRENT TRENDS AND LATEST MODEL DATA. GIVEN SOME BREAKS IN THE
CLOUDS AND DECENT SOUTHERLY WIND OVER THE SOUTHERN THIRD OF THE
CWA...HIGHS WERE RAISED SEVERAL DEGREES TO GET MAX TEMPS IN THE LOWER
TO MIDDLE 70S. LOWS IN THIS SAME GENERAL AREA WERE ALSO RAISED A FEW
DEGREES WITH THE THINKING THAT THE FRONTAL BOUNDARY WILL NOT MOVE
THIS FAR SOUTH. DEWPOINTS WERE ALSO RAISED TO ACCOUNT FOR THE HIGHER
THAN EXPECTED HUMIDITY. POPS WERE ADJUSTED SLIGHTLY DOWNWARD IN THE SE
QUADRANT FOR TODAY AND TONIGHT ON THE ORDER OF 10 TO 20 PERCENT. THIS
AREA MAY ESCAPE THE HEAVIEST RAINFALL WITH THIS EVENT. /DH/

&&

.HAZARDS...UPDATED HWO TO KEEP THREAT OF HEAVY RAINFALL GOING
THROUGH TONIGHT AND EXPAND INTO AREAS FARTHER N...BUT STILL S OF HWY
82. MODELS SHOW PERSISTENT MODERATE TO STRONG LOW LEVEL MOISTURE
TRANSPORT INTO STATIONARY BOUNDARY THROUGH 06Z-12Z TONIGHT. THIS
SHOULD RESULT IN REGENERATIVE AREAS OF CONVECTION WHICH WILL MOVE
E/ENE ALONG FRONT. MODELS AND HPC QPF AGREE ON WIDESPREAD 1 TO 2
INCH RAINFALL TOTALS...AND EXPECT SOME LOCALIZED HEAVIER AMOUNTS DUE
TO TRAINING. GIVEN RECENT COLD WEATHER...EXPECT THERE WILL BE GOOD
RUNOFF (AND CLOGGING OF SOME STORM DRAINS BY LEAVES)...AND WILL
PROBABLY SEE SOME LOCALIZED PONDING/URBAN FLOODING PROBLEMS.

AS FAR AS SEVERE POTENTIAL...DEWPOINTS SEEM TO BE RECOVERING A BIT
MORE THAN MODELS EXPECTED...WITH MID/UPPER 60S DEWPOINTS NOW INTO
FAR SOUTHERN PART OF FORECAST AREA (NOTE 68 DEWPOINT AT KESF). THIS
SHOULD RESULT IN AT LEAST MARGINAL INSTABILITY THROUGH TONIGHT. AS
CYCLOGENESIS OCCURS AND WIND FIELDS INCREASE...EXPECT SOME RISK FOR
STRONG/LOCALLY SVR CONVECTION ESPECIALLY TONIGHT...WITH DAMAGING
WIND THE PRIMARY THREAT. LOW LEVEL FLOW LOOKS TOO VEERED FOR MORE
THAN A SMALL TORNADO RISK ALTHOUGH ENOUGH LOW LEVEL SHEAR DOES EXIST
SO THAT IT WILL NEED TO BE MONITORED. MAIN STRONG/SEVERE RISK SHOULD
BE ALONG/S OF FRONT WHICH PUTS IT MAINLY S OF I-20. FARTHER NORTH...
ELEVATED INSTABILITY SHOULD RESULT IN AT LEAST ISOLATED STORMS.
MAGNITUDE OF INSTABILITY/LAPSE RATES DOES NOT SEEM TO SHOW MUCH OF A
HAIL THREAT...ALTHOUGH STRENGTH OF DEEP LAYER SHEAR WOULD IMPLY
THREAT IS NON ZERO. OVERALL IT DOES NOT APPEAR AS IF SETUP EVER
BECOMES ORGANIZED ENOUGH TO RESULT IN A WELL DEVELOPED SEVERE THREAT
BUT WILL OF COURSE CONTINUE TO MONITOR THROUGH THE DAY. /AEG/

&&

.AVIATION...WIDESPREAD IFR/LIFR CONDITIONS EXPECTED TO PERSIST ALONG
AND NORTH OF STATIONARY FRONT WHICH CURRENTLY LIES NEAR I-20.
CONTINUED MODERATE TO STRONG ISENTROPIC UPGLIDE ALONG AND NORTH OF
BOUNDARY SHOULD RESULT IN REGENERATION OF AREAS OF RAIN/TSRA ALONG
AND NORTH OF FRONT THROUGH ABOUT 12Z. CURRENT MVFR/VFR CONDITIONS
ALONG HWY 82 CORRIDOR SHOULD DETERIORATE TO IFR/LIFR BY THIS
EVENING. KHBG SHOULD SEE LESS IN THE WAY OF PRECIP UNTIL LATE
TONIGHT WHEN CYCLOGENESIS AND ASSOCIATED INCREASING LIFT RESULTS IN
INCREASED PRECIPITATION AND CONVECTIVE POTENTIAL IN WARM SECTOR. CIGS
SHOULD ALSO BE MVFR/VFR FOR THE MOST PART AT KHBG UNTIL
TONIGHT...WHEN INCREASING LOW LEVEL MOISTURE AND PRECIPITATION SHOULD
RESULT IN IFR CONDITIONS. /AEG/

TOWARDS THE OUTLOOK AREA THIS AFTERNOON...AN AREA OF LOW PRESSURE AT
THE SURFACE WILL ALSO DEVELOP AND TRACK EAST. WHILE INSTABILITY WILL
BE LIMITED AHEAD OF THIS SYSTEM...ADEQUATE WIND SHEAR OVER THE AREA
WILL AID IN THE DEVELOPMENT OF ISOLATED STRONG STORMS WHICH WILL HAVE
THE POTENTIAL TO PRODUCE WIND GUSTS OF 40 TO 50 MPH.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

.SPOTTER CALL TO ACTION STATEMENT...
THE ACTIVATION OF STORM SPOTTERS...HAM RADIO OPERATORS...AND
