Tornadoes and Flash Flooding in Mississippi, May 5 to 6, 2009

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
1015 AM CDT TUE MAY 5 2009

.UPDATE...LATEST SURFACE ANALYSIS HAS THE STALLED FRONTAL BOUNDARY
JUST SOUTH OF OUR AREA NEAR THE INTERSTATE 10 CORRIDOR. VISIBLE
SATELLITE IMAGERY SHOWS SOME ENHANCED CU DEVELOPING ALONG THE
BOUNDARY ALREADY THIS MORNING. THE BOUNDARY IS STILL EXPECTED TO
DRIFT NORTH THIS AFTERNOON INTO THE SOUTHERN PORTIONS OF OUR AREA
AND RESULT IN THE GREATEST CHANCE FOR RAIN THERE THIS AFTERNOON.
ALTHOUGH WATER VAPOR IMAGERY/RUC ANALYSIS SUGGESTS THAT THE WEAK
SHORTWAVE THAT HELP SPAWN OVERNIGHT AND EARLY MORNING SHOWERS HAS
SHIFTED EAST OF OUR AREA...LOCAL RADARS STILL HAD ISOLATED TO
SCATTERED SHOWERS CONTINUING NORTH OF INTERSTATE 20. THIS ACTIVITY
IS EXPECTED TO BECOME MORE ISOLATED AFTER NOON. MINOR ADJUSTMENTS TO
CLOUDS...POPS AND MORNING THUNDERSTORM WORDING. UPDATES HAVE BEEN
POSTED. /22/

&&

.PREVIOUS DISCUSSION...SHORT TERM...TODAY THROUGH WEDNESDAY
NIGHT...CERTAINLY NOT AN EASY FORECAST TO TRY AND FIGURE OUT OVER
THE NEXT 48 HOURS.  MODELS CONTINUE TO SHOW A COUPLE OF THUNDERSTORM
COMPLEXES AFFECTING THE FORECAST AREA THROUGH THE PERIOD AS A
STALLED FRONTAL BOUNDARY THAT'S CURRENTLY STALLED TO THE
SOUTH...BEGINS TO LIFT NORTHWARD ACROSS THE AREA LATER THIS
AFTERNOON AND THROUGH TONIGHT.  MODELS AGAIN AGREE IN SHOWING
THIS...BUT AS FOR TIMING AND EXACT TRACK OF THESE COMPLEXES...MODELS
REALLY HAVEN'T BEEN MUCH HELP IN NAILING DOWN THESE FINER DETAILS.
AS A RESULT...THE FORECAST THROUGH MUCH OF THE PERIOD WILL BE QUITE
THE BLEND OF MODELS...OPINION...AND THINKING AS TO THE OVERALL
MANNER OF HOW THE LAST COUPLE OF COMPLEXES MOVED THROUGH THE AREA
DURING THE PREVIOUS FEW DAYS.

FIRST OFF THOUGH...WITH THE BEFORE MENTIONED FRONT NEARLY STALLED
OUT ALONG TO JUST SOUTH OF A KHBG TO KMCB LINE...RADAR THIS MORNING
CONTINUE TO SHOW SOME SCATTERED ELEVATED CONVECTION SHIFTING EAST
SOUTHEAST ACROSS AREAS MAINLY ALONG AND NORTH OF THE INTERSTATE 20
CORRIDOR AS A WEAK TROUGH CONTINUES TO SWING EAST ACROSS THE MID
SOUTH.  THIS ACTIVITY WILL CONTINUE TO DO SO THROUGH THE MORNING
HOURS.

THE THINKING FOR TODAY IS THAT MOST OF THE CONVECTION WILL LATER
SHIFT AND STAY SOUTH OF THE INTERSTATE 20 CORRIDOR IN THE VICINITY
OF THE STALLED BOUNDARY.  A FEW STRONG STORMS...ONE OR TWO IN WHICH
COULD BRIEFLY REACH SEVERE LIMITS...COULD BE POSSIBLE MAINLY ACROSS
THE SOUTHWEST AS THE FRONT BEGINS TO PIVOT NORTHWARD LATER THIS
AFTERNOON.  INSTABILITY LOOK BETTER IN THIS AREA AND WITH DECENT
LAPSE RATES RESIDING IN THE AREA...THINKING IS THAT HAIL WILL BE THE
BIGGEST CONCERN...BUT CERTAINLY WON'T RULE OUT SOME GUSTY WINDS.

THE FRONT WILL CONTINUE TO LIFT NORTHWARD ACROSS MAINLY WESTERN
PORTIONS OF THE FORECAST AREA THROUGH LATE TONIGHT.  DEEP GULF
MOISTURE WILL ALSO SURGE NORTHWARD IN THE WAKE OF THE FRONT.  AS IT
DOES SO...A FAIRLY DECENT UPPER LEVEL DISTURBANCE WILL SWING ACROSS
THE REGION CAUSING A COMPLEX OF THUNDERSTORMS TO DEVELOP NEAR TO
JUST NORTH OF THE ARKLATEX AND RAPIDLY RACE EAST SOUTHEAST ALONG THE
FRONTAL BOUNDARY AND IMPACTING AT LEAST THE WESTERN HALF OF THE
FORECAST AREA AFTER MIDNIGHT TONIGHT...AND CONTINUE TO THROUGH THE
FORECAST AREA DURING WEDNESDAY.

I'VE GONE AHEAD AND HOISTED A FLASH FLOOD WATCH...WHICH WILL RUN
FROM 00Z THIS EVENING THROUGH 12Z WEDNESDAY MORNING...FOR AREAS
MAINLY ALONG AND NORTH OF A LINE FROM RAYVILLE LOUISIANA...TO
VICKSBURG MISSISSIPPI...TO YAZOO CITY...TO WINONA.  LOCATIONS ACROSS
THIS AREA OVER THE PAST FEW DAYS HAS ALREADY RECEIVED AMOUNTS
RANGING FROM 2 TO 5 INCHES.  WITH ANOTHER 1 TO 3 TO LOCALLY 4 INCHES
OF RAIN POSSIBLE LATE TONIGHT INTO WEDNESDAY MORNING...FLASH
FLOODING WILL LIKELY OCCUR IN SOME LOCATIONS ACROSS THIS AREA.
DEPENDING UPON HOW THIS COMPLEX EVOLVES AND TRACKS...THIS WATCH AREA
COULD BE EXPANDED IN BOTH TIME AND AREA IF NEEDED BY LATER SHIFTS.

IN ADDITION...GIVEN THE EXPECTED NATURE OF THE COMPLEX...SOME OF
THE STORMS COULD BE SEVERE WITH STRONG DAMAGING STRAIGHT LINE
WINDS AND HAIL BEING THE PRIMARY CONCERNS...BUT A BRIEF TORNADO OR
TWO CAN'T BE RULED OUT.

THE COMPLEX WILL CONTINUE TO SHIFT EAST ACROSS THE CWA THROUGH THE
DAY WEDNESDAY.  BY THIS TIME...THE FRONT WILL BE NORTH OF THE
FORECAST AREA WITH MOST...IF NOT ALL...OF THE CWA RESIDING IN SOME
PRETTY JUICY AIR.  DURING THIS TIME AND INTO WEDNESDAY
NIGHT...ANOTHER UPPER LEVEL DISTURBANCE IS PROGGED TO SEND YET
ANOTHER COMPLEX OF STORMS TOWARDS THE CWA.  WHERE THIS COMPLEX WILL
EXACTLY MOVE ACROSS THE FORECAST AREA IS AGAIN A BIT OF AN UNKNOWN.

TYPICALLY AS THE FIRST COMPLEX MOVES THROUGH...IT'LL SEND AN OUTFLOW
BOUNDARY SOUTH THAT EVENTUALLY STALLS OUT.  THEN WHEN THE NEXT
COMPLEX MOVES THROUGH...IT'LL RIDE THE NEW BOUNDARY ACROSS THE AREA.
HERE IN THOUGH LIES THE PROBLEM.  THE EXACT TRACK OF THIS SECOND MCS
WILL BASICALLY DEPEND ON THE PLACEMENT OF THE LEFT OVER BOUNDARY
FROM THE FIRST...TONIGHT'S...MCS.  MODELS SHOW THIS SECOND COMPLEX
MOVING EAST ALONG THE ORIGINAL FRONT...BUT AS WE'VE OBSERVED WITH
THESE SYSTEMS THE PAST FEW DAYS...THE NEXT SYSTEM TENDS TO BE A
LITTLE FURTHER SOUTH WERE AGAIN THE NEW BOUNDARY IS AND THE BETTER
JUICER AIR RESIDES.  FOR THE MEANTIME...AS FAR AS POPS ARE CONCERNED
FOR WEDNESDAY NIGHT...I STUCK WITH GUIDANCE GIVEN THE UNKNOWN AS TO
WHERE THINGS WILL SETUP FOR THE PASSAGE OF THE NEXT COMPLEX. /19/

.LONG TERM...ACTIVE AND CHALLENGING WEATHER PATTERN LOOKS REMAIN THE
CASE FOR THE LATTER PORTION OF THE WEEK. MUCH OF WHAT OCCURS THU-FRI
WILL HIGHLY DEPEND ON HOW THE SYSTEM FRO TONIGHT-WED WORKS OUT. AS
WAS MENTIONED WITH LAST NIGHTS FORECAST...NW FLOW PATTERN WILL BE
OVER THE REGION AND THAT BRINGS MUCH TIMING UNCERTAINTY TO
INDIVIDUAL WAVES. ADDITIONALLY...EACH WAVE WILL HAVE TO WORK WITH AN
ATMOSPHERE THAT WAS DISRUPTED BY AN EARLIER SYSTEM AND KNOWING WHERE
BOUNDARIES AND INSTABILITY AXIS WILL EXIST IS KEY...BUT DIFFICULT
TO PIN POINT. TRADITIONALLY...THESE NW FLOW SETUPS STEADILY PROGRESS
TAD S WITH EACH WAVE. HOWEVER...MODEL GUID IS NOT FOLLOWING THIS
PROGRESSION AND ACTUALLY PUSHES EACH STORM CLUSTER A TAD FURTHER N
WITH EACH WAVE PASSAGE. ONE THING THE MODELS DO HAVE SOME AGREEMENT
WITH IS THAT THE MORE SUBSTANTIAL WAVE WITH THE GREATEST LARGE SCALE
DYNAMICS WILL IMPACT THE AREA TONIGHT INTO WED. FOR THE END OF THE
WEEK INTO THE WEEKEND...HUGE QUESTION MARKS EXIST ON TIMING EACH
DISTURBANCE. ALSO...THESE SEEM TO BE SMALLER IN SCOPE WHICH MAY ONLY
RESULT IN SMALLER COMPLEXES. HOWEVER...JUST BECAUSE THEY MAY BE
SMALLER...DOESN'T MEAN THEY WON'T PACK A PUNCH. THE ATMOSPHERE WILL
CONTINUE TO BE QUITE UNSTABLE ALONG AND AHEAD OF ANY STALLED SFC
BOUNDARY WITH SOLID LAPSE RATES IN PLACE. AT THIS TIME...I CAN SEE
SOME COMPLEX OR A PORTION OF A COMPLEX BRING SOME STRONG/SVR STORMS
TO THE AREA THU INTO THU NIGHT WITH EVEN A BIT MORE POSSIBLE FRI
INTO SAT. HOWEVER...TOO MUCH UNCERTAIN EXISTS IN WHERE/WHEN THIS MAY
OCCUR BEYOND THU NIGHT. THUS I WILL HOLD OF ON MENTIONING ANY SVR
FOR FRI INTO SAT. I DO HAVE ENOUGH CONFIDENCE TO MENTION A RISK OF
SOME STRONG/SVR STORMS FOR THU INTO THU NIGHT. AT THIS TIME...I WILL
LEAN CLOSER TO THE GUID...BUT STILL STAY ON THE SOUTHERN EDGE OF
WHAT THEY SUGGEST. I WILL MENTION THE RISK FOR THE N HALF OF THE CWA
AS A START WITH WINDS/HAIL BEING THE PRIMARY RISK FROM SOME COMPLEX
OF STORMS.

AS FOR THE FORECAST ELEMENTS...GUID TEMPS AND POPS WERE GENERALLY
ACCEPTED AS IT DID SEEM TO COVER THE UNCERTAINTY IN TIMING AND
LOCATION. I DID TWEAK HIGH TEMPS DOWN A TAD FOR THU AS UPPER 90S MAY
BE TOUGH TO ACHIEVE AS WE WILL HAVE TO OVERCOME VERY WET SOILS ALONG
WITH CLOUDS AND POSSIBLY SOME LEFT OVER OUTFLOW BOUNDARY OR EVEN
PRECIP. AS FOR POPS...THE FOCUS WILL CONTINUE TO BE ACROSS THE N
HALF OF THE CWA THROUGH THE PERIOD AND I HAVE USED A MIX OF THE
LATEST GUID AND PREV FORECAST. POPS WILL CONTINUE TO RANGE FROM
20-30% FROM FRI-MON.  /CME/

.AVIATION...UPDATED...VFR TO PERIODS OF MVFR FLIGHT CATEGORIES WILL
PREVAIL THROUGH THE REMAINDER OF THE DAY.  A FEW SITES WITH MVFR
CEILINGS SHOULD BEGIN TO SEE CLOUDS BREAK UP THROUGH THE REMAINDER
OF THE MORNING INTO THE AFTERNOON.  VISIBILITIES FOR MOST SITES
SHOULD REMAIN VFR THROUGH THE REMAINDER OF THE MORNING AND INTO THE
AFTERNOON.  CONVECTION IS EXPECTED TO DEVELOP THIS AFTERNOON MAINLY
ACROSS AREAS SOUTH OF THE INTERSTATE 20 CORRIDOR WHERE A WARM FRONT
WILL BEGIN TO LIFT NORTHWARD LATER THIS AFTERNOON.  SITES WHERE
SHOWERS AND THUNDERSTORMS ARE OBSERVED WILL EXPERIENCE AT MINIMUM
MVFR CONDITIONS...WITH A BRIEF PERIOD OF IFR TO LIFR CONDITIONS
POSSIBLE IF CAUGHT UNDER A HEAVIER DOWNPOUR.  BY LATE TONIGHT INTO
EARLY WEDNESDAY MORNING...A COMPLEX OF STORMS IS EXPECTED TO MOVE
INTO NORTHWEST PORTIONS OF THE AREA.  THIS COMPLEX IS EXPECTED TO
MOVE SOUTH AND EAST THROUGH THE OVERNIGHT HOURS.  SITES IN THE PATH
OF THIS COMPLEX WILL AGAIN SEE A PROLONGED PERIODS OF IFR TO LIFR
CONDITIONS POSSIBLE. /14/
