AREAS AFFECTED...PARTS OF CENTRAL/SWRN MO...SERN KS...AND NERN OK

CONCERNING...TORNADO WATCH 395...

VALID 310039Z - 310145Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 395 CONTINUES.

REGIONAL RADARS SHOWED STRONGER...LONG-LIVED STORMS HAVE MOVED INTO
WW 394 ACROSS EAST CENTRAL MO AND CENTRAL IL. HOWEVER...
ADDITIONAL...MORE ISOLATED TSTMS CONTINUE TO DEVELOP SWWD ALONG A
PRE-FRONTAL TROUGH WHICH EXTENDED FROM CENTRAL MO...20 NNW COU...TO
SERN KS...40 ENE CNU TO 25 NNE PNC. EARLY EVENING SURFACE ANALYSIS
SHOWED A COLD FRONT EXTENDING FROM ERN WI SWWD THROUGH FAR SERN IA
TO EAST CENTRAL KS AND INTO NWRN OK TO THE NRN TX PANHANDLE.

AIR MASS ACROSS MUCH OF WRN/CENTRAL MO INTO NERN/CENTRAL OK REMAINS
MODERATELY-VERY UNSTABLE WITH MLCAPE VALUES RANGING FROM 2000-3000
J/KG. 00Z SGF SOUNDING SHOWED CAP HAD WEAKENED SINCE THE SPECIAL
SOUNDING AT 18Z...WHICH IS INDICATIVE OF THE RECENT INCREASE IN TSTM
ACTIVITY HAVING BECOME MORE ROBUST ALONG PRE-FRONTAL TROUGH IN
MO/SERN KS. EFFECTIVE BULK SHEAR REMAINS SUPPORTIVE OF ORGANIZED
STORMS...BUT WEAK LOW LEVEL SHEAR WOULD SUGGEST THE TORNADO THREAT
ACROSS CENTRAL/SRN PART OF WW 395 IS LOWER THAN WITH EARLIER
ACTIVITY FARTHER N. HAIL AND STRONG WIND GUSTS SHOULD BE THE
PRIMARY THREATS THIS EVENING. CONVECTIVE DEVELOPMENT FARTHER SWWD
INTO OK DOES NOT APPEAR LIKELY...GIVEN THE CAP OBSERVED ON THE 00Z
OUN SOUNDING.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0752 PM CDT FRI MAY 30 2008

VALID 310100Z - 311200Z

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE LWR GRTLKS REGION SWWD
ACROSS THE MIDWEST TO THE CNTRL PLAINS...

...MIDWEST/GRTLKS REGION...
WATER VAPOR SHOWED A DIGGING MID-LEVEL WAVE OVER MN THAT IS PROGGED
TO MOVE INTO THE GRTLKS REGION TONIGHT. ALONG THE BASE OF THIS
TROUGH...UPR FLOW WAS BEING ENHANCED WITH A BROAD 65-75 KT H5 JET
MOVING THROUGH THE MIDWEST. THUS...DESPITE SOMEWHAT VEERED FLOW
REGIME...SPEED SHEAR WAS SUFFICIENT FOR SUPERCELLS OVER A LARGE
PORTION OF THE MIDWEST. TSTMS THAT DEVELOPED EARLIER ALONG SRN
FRINGE OF MORNING MCS GREW INTO SEVERAL SUPERCELLS ACROSS CNTRL
SECTIONS OF IND/IL BY MID/LATE AFTN WITH LARGE HAIL...DMGG WIND
GUSTS AND A FEW TORNADOES.

00Z MESOANALYSIS SHOWED THAT BOUNDARY LAYER MOISTURE WAS SLOWLY
IMPROVING ACROSS THE OH VLY DOWNSTREAM FROM CURRENT ACTIVITY. THIS
WILL LIKELY CONTINUE SUPPORTING SFC-BASED STG-SVR TSTMS FOR SEVERAL
MORE HOURS ACROSS CNTRL/SWRN OH...SRN IND...SRN IL. STRONGER
INSTABILITY WILL RESIDE FROM INDIANA WEST WHERE 00Z SOUNDINGS
EXHIBITED THE STEEPEST MID-TROPOSPHERIC LAPSE RATES. FARTHER
E...WHILE MODEST NIGHTTIME DESTABILIZATION WILL OCCUR...BUOYANCY
WILL BE LESS. AS A RESULT...SUPERCELL STRUCTURES WILL LIKELY LAST
LONGER FROM CNTRL/SRN IND AND SRN IL...WITH ACTIVITY EVOLVING INTO
SMALL SCALE BOWS/LEWPS WITH TIME AND EWD EXTENT TOWARD THE MID/UPR
OH VLY OVERNIGHT. WHILE A COUPLE OF EVENING TORNADOES/LARGE HAIL
WILL STILL BE POSSIBLE ASSOCD WITH DISCRETE SUPERCELLS...A
TRANSITION INTO DMGG WINDS/HAIL WILL EXIST OVERNIGHT.

MEANWHILE...TO THE N...AS THE PRIMARY UPR TROUGH/HEIGHT FALLS GLANCE
OFF RESIDUAL INSTABILITY FROM NRN IL INTO SRN ONTARIO
TONIGHT...PRIMARILY ELEVATED STORM CLUSTERS WILL EVOLVE. LARGE HAIL
AND GUSTY WINDS CAN BE EXPECTED WITH THESE STORMS.

...CNTRL PLAINS/MO OZARKS...
IN WAKE OF THE MIDWEST/GRTLKS SYSTEM...A PRE-FRONTAL TROUGH
CONTINUES TO MAKE SEWD PROGRESS INTO THE MO OZARKS AND KS/NWRN OK
THIS EVENING. 00Z SGF SOUNDING SUGGESTS THAT AIR MASS FROM SWRN MO
WEST WAS SLIGHTLY CAPPED. GIVEN THAT LARGER SCALE HEIGHT FALLS WILL
PASS N AND E OF THE REGION LATER THIS EVENING...STRONGER TSTMS
SHOULD BE CONFINED TO AREAS FROM THE MO OZARKS NEWD INTO THE
MIDWEST. NOCTURNAL STORMS MAY INCREASE OVER PARTS OF KS/NRN OK TO
THE N OF THE SFC TROUGH AFTER 06Z AS A WEAK SSWLY LLJ INCREASES IN
THE ENTRANCE REGION OF THE MIDWEST UPR JET CORE.

I am sensing something tomorrow that is pretty much not being picked up by forecasts. It seems the system is moving slower now, and the threat will be more eastern OH/PA/MD/WV than the Mid-Atlantic. Something along the line of 1985 (hopefully not as severe - helicity isn't that great).

[CrazyC83]

No tornado warnings at this point.

CONCERNING...TORNADO WATCH 394...395...

VALID 310216Z - 310245Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 394...395...CONTINUES.

NEW WW WILL BE NEEDED ACROSS PARTS OF SERN MO TO SRN IND AND
POSSIBLY INTO PARTS OF WRN OH BY 03Z.

FARTHER SW ACROSS SWRN MO TO SERN KS...TSTMS COULD REMAIN STRONGER
FOR A FEW ADDITIONAL HOURS...WITH ACTIVITY WEAKENING BY LATE EVENING
AS FORCING FOR ASCENT MOVES AWAY FROM THIS REGION.

AT MID EVENING...REGIONAL RADARS SHOWED STRONG TO SEVERE TSTMS
EXTENDING FROM CENTRAL IND SWWD INTO CENTRAL MO. SWLY LOW LEVEL
FLOW WILL MAINTAIN MOISTURE ADVECTION INTO THE OH VALLEY AIDING
DESTABILIZATION. STRONGER INSTABILITY IS EXPECTED TO EXTEND WWD
FROM IND WHERE MID LEVEL LAPSE RATES ARE STEEPER PER 00Z SOUNDINGS.
ASCENT ATTENDANT TO MID LEVEL TROUGH AND DIFFLUENT FLOW APPROACHING
THE GREAT LAKES/LOWER OH VALLEY REGION IS EXPECTED TO MAINTAIN
ONGOING LINE OF TSTMS ESEWD DURING THE LATE EVENING AND OVERNIGHT
PERIOD. 50-60 KT WSWLY MID LEVEL WINDS ATOP STRENGTHENING SWLY LLJ
INTO THE OH VALLEY WILL MAINTAIN SUFFICIENT EFFECTIVE BULK SHEAR FOR
ORGANIZED STORMS. ACTIVITY HAS BECOME ORIENTED MORE PARALLEL TO THE
DEEP LAYER SHEAR VECTORS WHICH SHOULD SUPPORT MORE OF A QUASI-LINEAR
MODE WITH DAMAGING WINDS BEING THE PRIMARY THREAT OVERNIGHT.
HOWEVER...STRONGER LOW LEVEL SHEAR ALONG THE LLJ AXIS COULD SUPPORT
AN ISOLATED TORNADO THREAT.
