AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1110 AM CST TUE FEB 23 2016

.UPDATE...

THE SEVERE THREAT REMAINS GENERALLY THE SAME IN THIS MORNING
UPDATE...WILL HAVE A KJAN SPECIAL SOUNDING FOR 11 AM AND POSSIBLY
ONE AT 2 PM DEPENDING ON SHOWER/TSTM COVERAGE AT THAT TIME. THE
SEVERE THREAT WILL EVOLVE QUICKLY LATE THIS AFTN/EVNG WITH LATEST
HRRR GUIDANCE SUGGESTING A MORE CONDENSED TIMING WINDOW AND HAVE
REFLECTED THIS IN LATEST TIMING GRAPHIC. INITIAL STORMS ASSOCIATED
WITH WARM ADVECTION MOVING UP FROM SOUTHEAST LA COULD BE A CONCERN IN
THE HATTIESBURG AREA AFTER 200 PM...BUT MAIN CONCERN WILL BE FOR
CONVECTIVE SYSTEM DEVELOPING AHEAD OF STRONGER MID LEVEL DRY PUNCH
AND WITH BETTER SFC PRESSURE FALL/RISE COUPLET LATE THIS AFTN/EARLY
EVENG. /EC/

&&

.AVIATION...POOR CONDITIONS FOR FLYING CAN BE EXPECTED THROUGH
WEDNESDAY. WIDESPREAD IFR CATEGORY CEILINGS WILL CONTINUE DUE TO LOW
STRATUS. THUNDERSTORMS WILL ERUPT OVER MOST OF THE AREA BY MID/LATE
AFTN WITH SEVERE STORMS LIKELY...ESPECIALLY AFFECTING
JAN/HKS/GTR/MEI/HBG IN THE 22-04Z TIME PERIOD. RAIN WILL ALSO AFFECT
KGLH/KGWO THROUGH THE DAY AS WELL AS INTO TONIGHT AND EARLY
WEDNESDAY. OUTSIDE OF STORMS...STRONG SOUTHERLY WINDS WILL OCCUR
TODAY AHEAD OF THE SEVERE STORMS WITH SUSTAINED WINDS AROUND 15-20KTS
AND GUSTS TO NEAR 25-30KTS...SHIFTING TO WEST BEHIND THE FRONT
TONIGHT. NOTE THAT WINDS COULD BE QUITE VARIABLE IN THE GLH/GWO AREA
CLOSER TO THE LOW CENTER TRACK. /28/EC/

.PREV DISCUSSION... /ISSUED 434 AM CST TUE FEB 23 2016/

..SEVERE STORMS WITH POTENTIAL FOR STRONG TORNADOES LIKELY TODAY...

SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT...

OVERALL...THINKING HAS NOT CHANGED TOO MUCH IN TERMS OF TODAYS
SEVERE WEATHER EVENT. THE MID LEVEL TROUGH THAT IS LOCATED ACROSS
THE TEXAS PANHANDLE THIS MORNING WILL DEEPEN AS IT EJECTS NORTH AND
EAST TOWARD ARKANSAS AND TAKES ON A SLIGHT NEGATIVE TILT. AS IT
DOES...THE SFC LOW THAT IS BEGINNING TO DEVELOP ACROSS CENTRAL TEXAS
CURRENTLY WILL RAPIDLY DEEPEN THIS MORNING INTO THIS AFTERNOON. AS
THIS OCCURS THE STALLED FRONT ACROSS OUR AREA ASSOCIATED WITH THIS
LOW WILL MOVE NORTH AS A WARM FRONT ACROSS THE ARKLAMISS REGION
THROUGH THE AFTERNOON. WINDS OVER THE AREA...IN RESPONSE TO THE
DEEPENING APPROACHING LOW PRESSURE AREA...WILL INCREASE
SIGNIFICANTLY AT ALL LEVELS THROUGH THE AFTERNOON. WINDS AT 925MB
WILL INCREASE TO 20KTS BY 18Z AND 40-50KTS BY 00Z AS WELL AS 850MB
WINDS INCREASING TO NEAR 50KTS. THIS WILL HELP PUMP PLENTY OF
MOISTURE INTO OUR REGION SOUTH OF THE WARM FRONT. DEWPOINTS SHOULD
INCREASE TO THE LOWER 60S ACROSS SOUTHERN AREAS AND UPPER 50S ACROSS
MANY NORTHERN LOCATIONS NORTH OF I-20. WHILE ONE MIGHT INITIALLY
THINK THAT MOISTURE RETURN WOULDNT BE TOO SIGNIFICANT IN SOME PARTS
OF THE AREA...THE FORCING FROM THIS SYSTEM AS WELL AS ASSOCIATED
WIND FIELDS WILL BE PLENTY SUFFICIENT TO GENERATE SEVERE STORMS. AS
A 100KT MIDLEVEL 500MB JET CIRCLES AROUND THE BASE OF THE UPPER
TROUGH AND FEEDS INTO THE SOUTHERN PART OF THE AREA...THIS WILL
ENHANCE THE ATMOSPHERIC SETUP EVEN MORE FOR SEVERE STORMS.

IN TERMS OF PARAMETERS...THE BEST INSTABILITY AS CHARACTERIZED BY
BOTH DEWPOINTS AND CAPE WILL BE IN THE SOUTH WITH MUCAPE AROUND 600-
1200 J/KG AND SBCAPE AROUND 500-900 J/KG. COUPLE THIS WITH MID LEVEL
LAPSE RATES AROUND 6.5-7 C/KM...DEEP LAYER WIND SHEAR AROUND 50KTS
AND HELICITY VALUES OF 300-400 M2/S2 NOT JUST IN THE SOUTH BUT
ACROSS MOST OF THE CWA AND THIS WILL ALLOW FOR DISCRETE SUPERCELLS
TO DEVELOP AHEAD OF THE FRONT AND THE POTENTIAL FOR NOT JUST SEVERE
STORMS BUT SIGNIFICANT SEVERE STORMS...MOST NOTABLY STRONG
TORNADOES. MODEL STRONG TORNADO PARAMETERS CONTINUE TO SHOW A
BULLSEYE NEAR OR IN THE NORTHERN GULF/COASTAL AREAS. THIS WOULD PUT
THE CWA ON THE NORTHERN GRADIENT OF THIS WHICH HAS BEEN SHOWN TO BE
A FAVORABLE AREA FOR STRONG TORNADOES.

SOME HI-RES GUIDANCE IS MORE ROBUST THAN OTHERS IN TERMS OF
DEPICTING TODAYS SEVERE EVENT. THEY ALL SEEM TO BRING SOME RAIN INTO
THE WESTERN PART OF MY REGION BY MID-MORNING WHICH WILL THEN MOVE
NORTHWARD AS THE SFC LOW RAPIDLY DEEPENS AND BEGINS TO TRACK
NORTHWARD. THEN THEY SHOW THE STRONGER/DISCRETE STORMS DEVELOPING BY
LATER INTO THE EARLY AFTERNOON CONTINUING INTO THE EVENING HOURS.
MANY OF THEM DO SEEM TO FAVOR THE SOUTHEAST/EAST PART OF THE CWA
WHICH WOULD BE EXPECTED GIVEN THE COMBINATION OF INSTABILITY AND
SHEAR IN THIS REGION...GENERALLY FROM AROUND BROOKHAVEN EASTWARD. AS
STORMS EXIT TO THE EAST...THERE IS SOME DEPICTION OF FORMING A SEMI
BROKEN LINE OF STORMS. THE GENERAL TIME FRAME FOR ACTIVITY IS NEAR
NOON OR A LITTLE AFTER THROUGH 9-10PM(GIVE OR TAKE AN HOUR).

ONE CONCERNING FACTOR IS THAT THE 00Z RUNS SEEMED TO CONTINUE A
SLIGHT TREND OF BRINGING THE SFC LOW A LITTLE FURTHER SOUTH INTO THE
CWA AS OPPOSED TO TRACKING IT ACROSS SOUTHEAST ARKANSAS. THE GFS
BEGAN THIS LAST NIGHT AND A FEW OTHERS SEEM TO FOLLOW THIS TREND THIS
MORNING. IF THIS IS THE CASE THEN I WOULD EXPECT MORE OF THE
STRONGER/SEVERE STORMS TO BE PUSHED FURTHER SOUTH. THIS WOULD IMPACT
HOW MUCH OF MY NORTHERN AREAS WILL SEE IN TERMS OF SEVERE WEATHER OR
THE MORE SIGNIFICANT OF SEVERE WEATHER. THIS WILL BE SOMETHING TO
CONSIDER WHEN MAKING ADJUSTMENTS TO THE HWO AND GRAPHICS.
OVERALL...NOTHING WILL CHANGE IN TERMS OF HAZARDS BUT SOME
ADJUSTMENTS WILL LIKELY OCCUR IN HOW MUCH OF THE NORTHERN
AREA(PARTICULARLY ALONG AND NORTH OF THE LOW TRACK) WILL BE IN AN
ELEVATED RISK AND WILL ALSO LOOK AT POSSIBLY REDUCING SOME OF THE
SIZE OF THE SIGNIFICANT RISK. STILL FEEL THAT THE BEST AREA FOR THAT
WILL BE IN THE SOUTH...A LITTLE CLOSER TO THE MODERATE RISK AREA
HIGHLIGHTED BY SPC.

IN TERMS OF RAINFALL...THE AREA COULD SEE 1-2.5 OR 3 INCHES OF RAIN
WITH THIS SYSTEM WHICH COULD EXACERBATE AREAS THAT SAW DECENT RAIN
YESTERDAY. HOWEVER...FEEL THAT THIS SYSTEM WILL BE PROGRESSIVE
ENOUGH THAT A FLASH FLOOD WATCH IS NOT WARRANTED BUT MAY CONSIDER
PUTTING SOMETHING IN THE HWO FOR HEAVY RAIN/LOCALIZED FLOODING
THREAT.

THE MORE POTENT STORMS SHOULD BE EXITING THE AREA BY 03-06Z AS THE
989MB SFC LOW TRACKS INTO SOUTHERN TENNESSEE AND THE UPPER LOW
ACROSS EASTERN ARKANSAS. AS THIS OCCURS...MOISTURE WILL CONTINUE TO
WRAP AROUND AND LIGHT TO OCCASIONALLY MODERATE RAIN WILL CONTINUE
ACROSS THE FORECAST AREA THROUGH TUESDAY NIGHT AND TAPER OFF FROM
SOUTHWEST TO NORTHEAST DURING THE DAY WEDNESDAY. I HAVE LEFT ALL
PRECIPITATION NOW IN THE FORECAST AS RAIN...HOWEVER AS THE
ATMOSPHERIC COLUMN COOLS IN RESPONSE TO THE COLD CORE LOW MOVING
THROUGH...I CANNOT RULE OUT THAT THERE COULD BE SOME RAIN/SNOW MIX
BEFORE THE PRECIPITATION COMPLETELY ENDS LATER TUESDAY NIGHT INTO
WEDNESDAY. MODEL SOUNDINGS SHOW AN ENTIRELY COLD COLUMN WITH THE
EXCEPTION OF THE LOWER ATMOSPHERE AND THIS WILL BE SOMETHING TO
MONITOR BUT NO IMPACTS OR ACCUMULATION OF SNOW ARE EXPECTED WITH
THIS. AS THE ENTIRE SYSTEM DEPARTS...MUCH COOLER AIR WILL MOVE IN
WITH HIGHS ON WEDNESDAY ONLY REACHING THE MID 40S THANKS TO STRONG
COLD AIR ADVECTION.

ONE LAST THING OF NOTE...A WIND ADVISORY WILL BE IN EFFECT TODAY
THROUGH TONIGHT FOR STRONG GRADIENT WINDS. AS THE SFC LOW DEEPENS
AND WINDS RESPOND...SOUTHERLY WINDS WILL BE STRONG ENOUGH TO POSE
ISSUES OUTSIDE OF STORMS. IN ADDITION...AS THE LOW CONTINUES ACROSS
THE AREA THE PRESSURE GRADIENT WILL REMAIN TIGHT EVEN BEHIND IT SUCH
THAT PORTIONS OF THE AREA...ESPECIALLY THE DELTA...WILL CONTINUE TO
SEE GUSTY NORTHERLY WINDS INTO WEDNESDAY. THIS ADVISORY MAY NEED TO
BE EXTENDED IN TIME FOR A PORTION OF THE AREA INTO WEDNESDAY. /28/

LONG TERM...THURSDAY THROUGH MONDAY...COOLER BELOW NORMAL TEMPS AND
DRIER CONDITIONS CAN BE EXPECTED FOR THE REST OF THE WORK WEEK AS WE
STAY UNDER A BROAD UPPER TROUGH. A DRY COLD FRONT WILL CONTINUE OUR
COOLER AIRMASS ON THURSDAY. HIGH PRESSURE WILL BUILD INTO THE REGION
ON FRIDAY. A WEAK SHORT WAVE WILL PASS THROUGH THE REGION ON SATURDAY
BRINGING SOME HIGH CLOUDS. HIGH PRESSURE WILL SWING EAST OF THE
REGION OVER THE WEEKEND PROVIDING SOME RETURN FLOW. UPPER FLAT
RIDGING WILL PUSH INTO THE CWA FROM THE WEST OVER THE WEEKEND. THIS
WILL PROVIDE MILDER TEMPERATURES FOR THE REGION. A SHORT WAVE TROUGH
ASSOCIATED WITH A COLD FRONT WILL PROVIDE OUR NEXT CHANCE OF RAIN FOR
SUNDAY NIGHT THROUGH MONDAY. THE MODELS WERE NOT IN GOOD AGREEMENT
WITH THE RAIN CHANCES FOR LATE SUNDAY INTO MONDAY...SO POPS WERE
LOWERED SOME. THE EURO HAD ONLY LIGHT RAIN CHANCES ON MONDAY WITH THE
FRONT HANGING TO THE NORTH....AND CANADIAN LOOK TO BE DRY FOR THAT
PERIOD WITH THE FRONTAL PASSAGE. HOWEVER MOST OF THE GFS ENSEMBLES
HAD RAIN WITH THE FRONT./17/
