Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Dec 23, 11:27 AM CST, 4 hours 37 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1127 AM CST WED DEC 23 2015

...SIGNIFICANT SEVERE WEATHER STILL A THREAT FOR NORTHERN PORTIONS OF
THE ARKLAMISS...

.UPDATE...

THE FORECAST HAS SIMPLIFIED IN THE NEAR TERM NOW THAT THE INITIAL
WARM ADVECTION THUNDERSTORM ACTIVITY HAS MOVED EAST OF THE
ARKLAMISS...AND MOST FOCUS HAS SHIFTED TO NORTHERN/WESTERN PORTIONS
OF THE AREA. THE OVERALL THINKING FOR SEVERE WEATHER IS GENERALLY
THE SAME WITH PRESSURE FALLS AND INCREASING CONVERENCE OVER THE DELTA
REGION HELPING TO DEVELOP DEEP CONVECTION...MOST LIKELY IN THE UPPER
ARKLAMISS DELTA REGION EXTENDING EAST ALONG THE HWY 82 CORRIDOR LATE
TODAY. IN THIS AREA...VERY IMPRESSIVE SHEAR/INSTABILITY (0-6 KM DEEP
LAYER SHEAR > 65KT AND MIXED LAYER CAPE APPROACHING 2000 J/KG) WILL
COMBINE WITH THE FORCING TO RAISE THE CONCERN FOR SUPERCELLS WITH
STRONG TORNADOES...ESPECIALLY FROM AROUND DERMOTT/GREENVILLE EAST TO
GRENADA WHERE THE LOW LEVEL FLOW WILL HAVE A BETTER CHANCE TO BACK
AND ENHANCE SREH. GIVEN THE CAPPED AIRMASS TO THE SOUTH...VERY RICH
MOISTURE IS ADVECTING NORTHWARD UNIMPEDED THROUGH THE HIGHLY MIXED
BOUNDARY LAYER WITH LOWER TO MID 70 DEWPOINTS HAVING MOVED INLAND
OVER LA. THIS SCENARIO IS QUITE RARE FOR LATE DECEMBER TO SAY THE
LEAST.

THE MOST UNCERTAINTY IN THIS SITUATION REGARDS THE CAP STRENGTH/LIFT AND
JUST HOW FAR SOUTH THE MORE VIGOROUS CONVECTION WILL EXTEND LATER
THIS AFTERNOON INTO THE EARLY EVENING. WE HAVE JUST CONDUCTED A
SPECIAL RAOB HERE AND IT STILL SHOWS A SIGNIFICANT CAP. AS OF NOW THE
BULK OF HIGH RES GUIDANCE IS RATHER BEARISH ON CONVECTIVE DEVELOPMENT
ALONG/SOUTH OF THE I-20 CORRIDOR WHERE THE CAP IS STRONGEST AND
PRESSURE FALLS WEAKEST. BASED ON THIS HAVE LOWERED THE SEVERE THREAT
OVER ESPECIALLY THE PINE BELT REGION AND HAVE ALSO LOWERED POPS FOR
THE AFTERNOON.

LOOKING FARTHER OUT IN TIME...THE FORECAST IS RATHER UNCLEAR
REGARDING JUST HOW MUCH CONVECTION WILL LINGER OVERNIGHT AND
REDEVELOP CHRISTMAS EVE...BUT IT DOES SEEM THERE COULD BE AN
INCREASING RISK FOR AT LEAST LOCALLY HEAVY RAINFALL. WILL BE
ASSESSING THIS CONCERN IN THE AFTERNOON FORECAST. /EC/

&&

.AVIATION...MVFR CIGS PREVAIL ACROSS THE REGION THIS MORNING DUE TO
LOW STRATUS. CIGS MAY IMPROVE TO VFR AT TIMES TODAY, BUT GENERALLY
MVFR WILL PERSIST. SHRA/TSRA WILL BECOME PREVALENT THIS AFTERNOON
ESPECIALLY NORTH OF I-20. SOME OF THESE STORMS COULD BE SEVERE THIS
AFTERNOON WITH LARGE HAIL AND GUSTY WINDS. THE WINDS WILL BE GUSTY
OUT OF THE SOUTH THIS AFTERNOON WITH GUSTS TO 30KTS POSSIBLE AT
GLH/GWO. THE THREAT FOR SEVERE STORMS WILL SLACKEN BY LATE TONIGHT,
BUT SOME SHRA/TSRA WILL REMAIN POSSIBLE MAINLY EAST OF I-55 THROUGH
THE OVERNIGHT HOURS AND INTO EARLY THURSDAY. CIG/VISBY REDUCTIONS TO
MVFR/IFR WILL BE POSSIBLE OVERNIGHT. /DL/

&&

.PREV DISCUSSION... /ISSUED 408 AM CST WED DEC 23 2015/

..SIGNIFICANT SEVERE WEATHER POSSIBLE TODAY...

SHORT TERM...TODAY THROUGH THURSDAY NIGHT...

AS WE PROGRESS THROUGH THE MORNING INTO THE AFTERNOON HOURS...WE MAY
GET A BREAK LATER THIS MORNING BEFORE A NEGATIVELY TILTED TROUGH
OVER THE PLAINS MOVES EAST TOWARDS THE AREA...AND A DEEPENING
SURFACE LOW MOVES FROM THE CENTRAL PLAINS INTO THE GREAT LAKES THIS
EVENING. A STRONG SHORT WAVE WILL ROTATE THROUGH THE TROUGH THIS
AFTERNOON AND THE ASSOCIATED SURFACE TROUGH WILL APPROACH THE DELTA
DURING THE EARLY AFTERNOON HOURS. THE SHORT WAVE WILL MOVE ACROSS
THE ARKLAMISS WITH THE BEST HEIGHT FALLS MAINLY OVER THE NORTHERN
PORTIONS OF THE AREA THIS AFTERNOON. THIS WILL COMBINE WITH VERY
STRONG SHEAR AND INSTABILITY...CREATING THE POTENTIAL FOR SEVERE
STORMS. GLOBAL MODELS SUGGEST ANYWHERE FROM 1000-2000 J/KG OF ML
CAPES AND DEEP LAYER SHEAR RANGING FROM 50-70KTS ACROSS MOST OF THE
AREA. THE NAM CONTINUES TO BE THE MOST BULLISH OF THE MODELS
INDICATING EVEN MORE INSTABILITY AND SHEAR. THE GREATEST CONCERN
CONTINUES TO BE GENERALLY NORTH OF THE I-20 CORRIDOR WHERE THE BEST
FORCING WILL EXIST. ALL MODES OF SEVERE WEATHER ARE
POSSIBLE...INCLUDING STRONG TORNADOES THIS AFTERNOON AND EARLY
EVENING. LESS FORCING WILL EXIST FURTHER SOUTH AS HEIGHT FALLS WILL
BE WEAK...BUT ANY STORMS THAT DUE FORM WILL STILL HAVE THE
POSSIBILITY OF BECOMING SEVERE...AS STRONG SHEAR AND INSTABILITY
WILL PREVAIL OVER THE ENTIRE AREA INTO THE EVENING HOURS.

EXPECT THE SEVERE RISK TO BEGIN TO DIMINISH AND SHIFT EAST AS WE
PROGRESS THROUGH THE EVENING HOURS AS MID LEVEL HEIGHT'S BEGIN TO
RISE. EXPECT LINGERING SHOWERS OR POSSIBLY SOME THUNDERSTORMS
ACTIVITY INTO THE NIGHT MAINLY SOUTH OF THE NATCHEZ TRACE CORRIDOR
AS GOOD MOISTURE TRANSPORT CONTINUES OVER THOSE AREAS. PWATS WILL
FALL BELOW AN INCH FOR AREAS NORTH OF THE NATCHEZ TRACE BY THURSDAY
MORNING...BUT MODELS SUGGEST THE MOISTURE WILL SURGE BACK NORTHWARD
WITH A WARM FRONT AS SOUTHERLY FLOW INCREASES BEHIND IT BY THURSDAY
NIGHT. THE FRONT MAY BE THE FOCUS OF THUNDERSTORM ACTIVITY THURSDAY
NIGHT...AND WITH H700-H500 LAPSE RATES CLOSE TO 7 C/KM...SOME LARGE
HAIL WILL BE POSSIBLE WITH THESE STORMS DURING THE OVERNIGHT HOURS.
THIS WILL HAVE TO BE MONITORED IN FUTURE FORECASTS FOR POSSIBLE
INCLUSION IN THE HWO AND GRAPHICASTS. /15/

LONG TERM...FRIDAY THROUGH TUESDAY...FRIDAY MORNING OUR FLOW ALOFT
WILL BE BACKING TO THE SOUTH SOUTHWEST IN RESPONSE TO A DEEPENING
UPPER LEVEL TROUGH OVER THE WESTERN CONUS. SURFACE RIDGING FROM THE
ATLANTIC WILL BE NOSING BACK ACROSS THE GULF COAST STATES. THIS WILL
HELP THE OLD STALLED FRONTAL BOUNDARY TO CONTINUE MOVING BACK NORTH
AS A WARM FRONT AND SERVE AS A FOCUS FOR CONVECTION FRIDAY. THE WARM
FRONT IS EXPECTED TO BE NEAR THE HIGHWAY 82 CORRIDOR AT SUNRISE AND
BE JUST NORTHWEST OF OUR CWA BY NOON FRIDAY. THIS WILL PLACE
OUR WHOLE CWA BACK IN THE WARM SECTOR WITH PWATS GREATER THAN AN INCH
AND A HALF AND SURFACE DEW POINTS IN THE UPPER 60S TO LOWER 70S.
GREATEST POPS WL BE CARRIED OVER OUR NORTHWEST ZONES FRIDAY BUT
THERE WL BE A CHANCE FOR RAIN AREAWIDE DURING THE HEAT OF THE DAY.
AFTERNOON HIGHS WILL BE MUCH WARMER THAN NORMAL TOPPING OUT FROM THE
MID 70S NORTH TO THE LOWER 80S SOUTH. NORMAL HIGHS RUN FROM THE
LOWER 50S NORTH TO THE LOWER 60S SOUTH. THE DEEPENING UPPER LEVEL
TROUGH OVER THE WESTERN CONUS WILL CLOSE OFF OVER THE DESERT
SOUTHWEST BY NOON SATURDAY AND SWING EAST TO THE TEXAS BIG BEND
REGION BY NOON SUNDAY. MODELS STILL DIFFER WITH THE TRACK OF THE
CLOSED LOW SUNDAY THROUGH TUESDAY WITH THE GFS BEING THE MOST
PROGRESSIVE AND FASTEST BRINGING THE ASSOCIATED COLD FRONT ACROSS
OUR CWA SUNDAY NIGHT. THE ECMWF IS THE SLOWEST WITH THE CLOSED LOW
AND BRINGS THE ASSOCIATED COLD FRONT THROUGH OUR CWA MONDAY NIGHT.
HAVE GONE CLOSER TO THE CANADIAN THROUGH SUNDAY AND MAINTAINED SOME
CONTINUITY FROM THE PREVIOUS FORECAST WITH MONDAY BEING THE FROPA
AND MAIN RAIN DAY. MUCH WARMER THAN NORMAL TEMPERATURES WITH MOSTLY
DIURNALLY DRIVEN RAIN CHANCES ARE EXPECTED THROUGH THE WEEKEND.
IT APPEARS THERE WILL BE A CHANCE OF SEVERE STORMS OVER OUR CWA
MONDAY ALONG AND AHEAD OF THE FRONT. COOLER AND MUCH DRIER AIR
IS EXPECTED TO BE BACK OVER OUR CWA TUESDAY. /22/
