Oh dear ... High Risk over the jungles of Mississippi and Alabama today ... you do not want to be chasing in that area today - 30% probability of tornadoes and lots of trees do not mix well!

DAY 1 CONVECTIVE OUTLOOK

NWS STORM PREDICTION CENTER NORMAN OK

1257 AM CDT SAT APR 24 2010

VALID 241200Z - 251200Z

...THERE IS A HIGH RISK OF SVR TSTMS PORTIONS SERN AR...NERN

LA...MS...CENTRAL/NRN AL...

...THERE IS A MDT RISK OF SVR TSTMS ELSEWHERE FROM PORTIONS E TX TO

CENTRAL/NRN LA...AL...WRN GA...TN...SRN/CENTRAL KY...EXTREME SERN

MO...CENTRAL/SRN/ERN AR....

...THERE IS A SLGT RISK OF SVR TSTMS SURROUNDING MDT RISK...FROM

GULF COAST OF SE TX TO FL PANHANDLE...TO PORTIONS WV/OH...TO

PORTIONS LOWER MO VALLEY REGION...TO E TX....

OUTBREAK OF NUMEROUS SVR TSTMS IS EXPECTED TODAY...GREATEST

CONCENTRATION/INTENSITY OF WHICH SHOULD INCLUDE STG-VIOLENT TORNADO

THREAT AFFECTING MID-SOUTH...MS DELTA REGION...AND TN VALLEY.

...SYNOPSIS...

SPLIT-FLOW PATTERN IN MID-UPPER LEVELS FEATURES CYCLONE INITIALLY

LOCATED OVER CENTRAL HIGH PLAINS...FCST TO MOVE EWD ACROSS KS TO WRN

MO BY 25/00Z AND WEAKEN ALONG WITH ITS SFC MANIFESTATION.

MEANWHILE...STG SHORTWAVE TROUGH AND SPEED MAX ALOFT -- WHICH

COMPRISED MOST OF INITIAL UPPER CYCLONE OVER SWRN CONUS DURING

PREVIOUS FEW DAYS -- IS FCST TO EJECT NEWD FROM CENTRAL TX TO ERN

MO/SRN IL AREA BY 25/00Z...TAKING OVER AGAIN AS PRIMARY 500 MB LOW.

BY THAT TIME...CORRESPONDING SFC CYCLONE WILL FORM ALONG OCCLUSION

TRIPLE POINT E OF ORIGINAL...AND CLOSE TO NEWER MID-UPPER CYCLONE

CENTER. THIS PROCESS WILL RESULT IN REINFORCEMENT/ACCELERATION OF

INITIALLY STALLED FRONTAL SEGMENT NOW OVER SWRN/CENTRAL TX NNEWD

OVER ERN OK. FRONT SHOULD MOVE ACROSS MUCH OF LA...WRN MS AND WRN

PORTIONS TN/KY BY 25/00Z...TO FL PANHANDLE...AL...MIDDLE-ERN TN AND

ERN KY BY END OF PERIOD....WHEN MID-UPPER CYCLONE SHOULD BE OVER NRN

PORTIONS IL/INDIANA...AND SRN LM AREA.

...LOWER MS VALLEY...MID-SOUTH AND TN VALLEY REGIONS...

TSTMS SHOULD BE INCREASING IN COVERAGE/INTENSITY AROUND BEGINNING OF

PERIOD OVER E TX...LA AND ARKLATEX REGION. FOREGOING AIR MASS --

ALREADY MOISTENED/DESTABILIZED FAVORABLY BY PRIOR/OVERNIGHT THETAE

ADVECTION...WILL FURTHER DESTABILIZE AMIDST SFC DIABATIC HEATING.

AMOUNT OF HEATING IS SOMEWHAT IN QUESTION BECAUSE OF POTENTIAL FOR

CLOUD/ANVIL DEBRIS SPREADING DOWNSTREAM IN MID-UPPER LEVELS FROM

EARLY CONVECTION...PERHAPS INCLUDING TEMPORAL EXTENSION OF ACTIVITY

NOW OVER S TX. STILL...AWAY FROM EXISTING CONVECTION...EVERY

REASONABLE SCENARIO INDICATES THAT MLCINH GENERALLY WILL WEAKEN WITH

NWD EXTENT FROM GULF COAST...SUPPORTING EARLY AND RAPID DEVELOPMENT

AND INTENSIFICATION OF TSTMS FROM MID-MORNING THROUGH

MID-AFTERNOON...AND SUSTAINED THREAT SHIFTING EWD AND NEWD ACROSS

OUTLOOK AREA INTO EVENING/OVERNIGHT HOURS.

INTENSE VERTICAL WIND PROFILES WILL SPREAD ACROSS BROAD WARM/MOIST

SECTOR TODAY...MUCH OF WHICH ALREADY IS IN PLACE ACROSS MUCH OF

LA...MS AND COASTAL AL. THIS AIR MASS WILL SPREAD INLAND TOWARD TN

VALLEY AS CONVECTION/PRECIP NOW OVER TN/AL/GA SHIFTS NEWD. SFC DEW

POINTS WILL BE 70S INVOF GULF COAST...TRANSITIONING TO UPPER 60S AS

FAR N AS TN AND LOW-MID 60S TO OH VALLEY. WEAKENING LAPSE RATES

ALOFT AND BUOYANCY WITH NWD EXTENT...FROM TN VALLEY TO OH VALLEY AND

GREAT LAKES...RENDER PROGRESSIVELY MORE CONDITIONAL NATURE TO SVR

THREAT...THOUGH KINEMATIC PROFILES WILL BECOME FAVORABLE OVER VERY

LARGE AREA S OF GREAT LAKES BY EVENING/OVERNIGHT HOURS.

MULTIPLE CONVECTIVE EPISODES AND STORM MODES ARE EXPECTED IN THIS

SITUATION...AGGREGATE OF WHICH SHOULD YIELD DENSE CONCENTRATION OF

SVR EVENTS BY END OF PERIOD ACROSS MDT/HIGH CATEGORICAL RISK AREAS.

THOUGH DISCRETE/CYCLIC TORNADIC SUPERCELLS ARE MOST POTENTIALLY

DANGEROUS THREAT...ESPECIALLY OVER HIGH RISK AREA...CLUSTERED AND

QUASI-LINEAR CONVECTIVE ELEMENTS WITH EMBEDDED BOW/LEWP FORMATIONS

AND SUPERCELLS ALSO APPEAR PROBABLE. STRENGTHENING DEEP-LAYER WINDS

AND RELATED FAST STORM MOTIONS PORTEND LONG TRACKS FOR SUPERCELLS

AND FOR SOME OF THEIR TORNADOES...AS WELL AS FOR SWATHS OF DAMAGING

WIND WITH ANY BOW/LEWP FEATURES. THIS SUPPORTS RATHER ROBUST

PROBABILITIES FOR ALL SEVERE MODES.

PARAMETER SPACES IN FCST SOUNDINGS OVER HIGH RISK AREA -- SHIFTING

NEWD FROM LATE MORNING THROUGH AFTERNOON -- INCLUDE 50-60 KT LLJ

SUPPORTING VERY LARGE HODOGRAPHS WITH 0-1 AND 0-1 KM SRH 300-600

J/KG. ALSO EXPECT 50-60 KT EFFECTIVE SHEAR MAGNITUDES BENEATH

110-140 KT 250 MB JET MAX AND 60-90 KT 500 MB WINDS...POTENTIALLY

JUXTAPOSED WITH MLCAPE 1500-2500 J/KG.

SUPERCELL/TORNADO THREAT MAY CARRY INTO EVENING/OVERNIGHT HOURS OVER

CENTRAL/SRN APPALACHIANS REGION AND WRN GA BEFORE DIMINISHING.

...IA...MO VALLEY REGION...

SCATTERED STG-SVR TSTMS ARE EXPECTED TO DEVELOP ACROSS THIS AREA

INVOF LARGE CYCLONE ALOFT...AS STEEP MID-UPPER LEVEL LAPSE RATES

COLLOCATED WITH BROAD AREA OF LOW-LEVEL CONVERGENCE AND

DIABATIC/DIURNAL DESTABILIZATION OF BOUNDARY LAYER. MAIN CONCERN

WILL BE SVR HAIL...THOUGH POTENTIAL FOR DAMAGING GUSTS EXISTS. SVR

POTENTIAL SHOULD WANE SIGNIFICANTLY AFTER SUNSET.

This sounds Downright Scary for the Deep South Today :lol:

PDS Issued a bit earlier as well (Particulary Dangerous Situation)

MESOSCALE DISCUSSION 0372

NWS STORM PREDICTION CENTER NORMAN OK

0931 AM CDT SAT APR 24 2010

AREAS AFFECTED...MID-SOUTH AND LOWER OH VLY

CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY

VALID 241431Z - 241530Z

TORNADO RISK WILL INCREASE ACROSS A LARGE PART OF THE MID-SOUTH AND

LWR OH VLY THROUGH THE AFTN. STRONG AND LONG-TRACKED TORNADOES WILL

BE POSSIBLE ALONG WITH VERY LARGE HAIL AND DMGG WIND GUSTS.

UPR AIR ANALYSIS SHOWS UPSTREAM TROUGH GOING NEGATIVE-TILT /100

METER 12-HR HEIGHT FALLS/ WITH AN EMBEDDED JET-STREAK PUNCHING ENE

INTO THE ARKLATEX REGION. THIS FEATURE WILL TRANSLATE INTO THE

MID-SOUTH/LWR OH VLY REGIONS THIS AFTN. SFC LOW OVER NCNTRL AR WILL

TRACK TO NEAR ST. LOUIS BY LATE AFTN AND UNDERGO CONSIDERABLE

DEEPENING.

MORNING STG/SVR TSTMS CLUSTERS WILL CONTINUE ENE THROUGH THE TN VLY

THROUGH EARLY THIS AFTN AND PROBABLY BECOME MORE ELEVATED WITH TIME

AS THEY MOVE TOWARD THE CUMBERLAND PLATEAU AND SRN APPALACHIAN

MOUNTAINS. SVR THREAT WILL SUBSEQUENTLY INCREASE UPSTREAM THIS

AFTN.

WARM SECTOR...CHARACTERIZED BY SFC DEW POINTS IN THE MID 60S TO LWR

70S WILL SURGE N IN WAKE OF MORNING ACTIVITY INTO ERN AR...SERN

MO...MIDDLE/WRN TN AND WRN KY AHEAD OF THE SFC LOW. THIS WILL

RESULT IN RAPID DESTABILIZATION AND SUBSEQUENT INCREASE IN TSTMS.

FCST LOW-LEVEL HODOGRAPHS WILL CONTINUE TO EXHIBIT TREMENDOUS 0-1KM

SRH VALUES 300-500+ M2/S2. THUS...ANY STORM WILL HAVE POTENTIAL FOR

STRONG...LONG-LIVED TORNADOES ALONG WITH VERY LARGE HAIL RISKS.

IT APPEARS THAT THE PRIMARY SVR EVENT MAY BE BEGINNING ACROSS

SCNTRL/SERN AR JUST AHEAD OF THE SFC LOW/WIND SHIFT. ACTIVITY

SHOULD GROW UPSCALE IN INTENSITY THROUGH THE AFTN ENE TOWARD THE

MEMPHIS/MID-SOUTH AREA AND TOWARD THE LWR OH VLY LATER THIS AFTN.

And that is why we DONT Chase in Mississippi. Because if the Tornado dont get you from behind the Forests that line the roads, the Trees will land on you :lol:

With it being so close to the Gulf as well the Storms look crappy and Grungy (No Structure) with Temp and Dewpoint spreads almost the same.

Absolute Nightmare of a Place!

Few chasers heading down there, including reed!
