0451 PM CDT TUE JUN 16 2009

AREAS AFFECTED...PARTS OF NRN OK...SERN KS...SW MO

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 162151Z - 162315Z

TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE THREAT AND THE
POSSIBILITY OF A WW.

CONVECTIVE INHIBITION STILL SEEMS STRONG ACROSS MUCH OF THE SOUTH
CENTRAL PLAINS...EVEN NEAR THE CREST OF THE BUILDING RIDGE NORTH OF
THE KANSAS/OKLAHOMA BORDER AREA. HOWEVER...A SUBTLE IMPULSE
EMBEDDED WITHIN THE BROADER SCALE FLOW MAY BE IN THE PROCESS OF
TURNING EAST NORTHEAST OF THE TEXAS/OKLAHOMA PANHANDLE REGION...IN
THE WAKE OF MUCH MORE SIGNIFICANT SHORT WAVES SHIFTING INTO/THROUGH
THE UPPER MISSISSIPPI AND LOWER OHIO VALLEYS.

IT APPEARS POSSIBLE THAT WEAK MID-LEVEL FORCING...COUPLED WITH THE
APPROACH OF CONVECTIVE TEMPERATURES IN PEAK AFTERNOON HEATING...IN
THE PRESENCE OF GENERAL LOW-LEVEL WARM ADVECTION MAY WEAKEN
INHIBITION ENOUGH TO SUPPORT BOUNDARY LAYER BASED CONVECTIVE
DEVELOPMENT PRIOR TO 00Z. IF THIS OCCURS...STORMS PROBABLY WILL
REMAIN ISOLATED TO WIDELY SCATTERED IN NATURE...BUT THEY COULD
RAPIDLY REACH SEVERE LEVELS IN THE PRESENCE OF STRONG POTENTIAL
INSTABILITY AND SUFFICIENT SHEAR FOR SUPERCELLS. BEST CHANCE FOR
THIS SEEMS TO BE NEAR/NORTH THROUGH EAST OF BARTLESVILLE...BUT
SOMEWHAT BETTER POTENTIAL FOR MORE SUBSTANTIAL STORM DEVELOPMENT MAY
NOT OCCUR UNTIL CLOSER TO 02-03Z...AS A STRENGTHENING LOW-LEVEL JET
FOCUSES LIFT A BIT FARTHER TO THE NORTH....ACROSS SOUTHEAST KANSAS
INTO THE MISSOURI OZARKS.

OTHER WATCH INFORMATION...CONTINUE...WW 433...WW 434...WW 435...

DISCUSSION...WELL-DEFINED BOW ECHO WITH DAMAGING WINDS IS MOVING EWD
ALONG THE SE KY/NE TN BORDER AT ABOUT 45 KT. THIS SYSTEM MAY TEND
TO PROPAGATE MORE ESEWD OVER THE NEXT FEW HOURS AS IT ENCOUNTERS AN

NC/VA. MEANWHILE...MORE ISOLATED STORMS ARE ONGOING ACROSS SC ALONG
THE SAME INSTABILITY GRADIENT. VERTICAL SHEAR AND INSTABILITY ARE
AT LEAST MARGINALLY FAVORABLE FOR SUPERCELLS ACROSS SC...WITH LARGE

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0739 AM CDT WED JUN 17 2009

VALID 171300Z - 181200Z

...THERE IS A MDT RISK OF SVR TSTMS THIS AFTERNOON AND TONIGHT
ACROSS PARTS OF NEB...EXTREME NORTHERN KS...SOUTHWEST IA...AND
NORTHWEST MO...

...THERE IS A SLGT RISK OF SVR TSTMS FROM THE CENTRAL PLAINS INTO
THE OH VALLEY AND SOUTHEAST STATES...

AN ACTIVE CONVECTIVE DAY IS ANTICIPATED TODAY ACROSS THE UNITED
STATES...WITH MULTIPLE AREAS OF SEVERE STORMS EXPECTED. IT APPEARS
AT THIS TIME THE AREA OF GREATEST THREAT WILL BE OVER PARTS OF THE
CENTRAL PLAINS...WHILE OTHER CONCENTRATED AREAS OF SEVERE OCCUR FROM
THE UPPER OH VALLEY SOUTHWARD INTO THE SOUTHEAST STATES.

...NEB/KS/IA/MO...
A LARGE UPPER RIDGE IS IN PLACE ACROSS THE SOUTHERN STATES
TODAY...WITH BAND OF STRONG MID LEVEL WINDS EXTENDING FROM THE
CENTRAL ROCKIES INTO THE MID/UPPER MS VALLEY...THEN
EAST-SOUTHEASTWARD TO THE CENTRAL APPALACHIANS. MODELS AGREE IN THE
DEVELOPMENT OF A SURFACE LOW BY THIS AFTERNOON OVER WESTERN KS WITH
BACKED LOW LEVEL WINDS EXPECTED TO THE NORTH OF THE LOW ACROSS MUCH
OF NEB. A HOT AND VERY MOIST AIRMASS WILL DEVELOP ACROSS THIS
REGION WITH DEWPOINTS IN THE UPPER 60S TO LOWER 70S AND TEMPERATURES
IN THE 90S. MODEL FORECAST SOUNDINGS ACROSS NEB THIS AFTERNOON SHOW
STEEP LOW AND MID LEVEL LAPSE RATES AND MLCAPE VALUES OF 4500+ J/KG.


IT APPEARS LIKELY THAT A COMBINATION OF DIURNAL HEATING AND WEAK
LARGE SCALE ASCENT BENEATH THE UPPER JET WILL WEAKEN THE CAP AND
LEAD TO SCATTERED THUNDERSTORMS THIS AFTERNOON FROM EXTREME
NORTHEAST CO INTO WESTERN AND CENTRAL NEB. THE INITIAL STORMS WILL
LIKELY BE SUPERCELLS CAPABLE OF VERY LARGE HAIL AND A FEW TORNADOES.
THIS ACTIVITY WILL TRACK EASTWARD ACROSS NEB DURING THE EVENING AND
IS EXPECTED TO COALESCE INTO A FAST-MOVING MCS AS STORMS SPREAD INTO
IA/KS/MO. THE POTENTIAL EXISTS FOR WIDESPREAD DAMAGING WINDS FROM
THIS CLUSTER OF STORMS ACROSS THE EASTERN HALF OF THE MODERATE RISK
AREA.

...MN/NORTHERN IA...
REMNANT WEAK UPPER LOW OVER ND WILL LIFT NORTHEASTWARD INTO SOUTHERN
CANADA TODAY...WHILE THE SURFACE LOW/TROF BECOMES ESTABLISHED ALONG
THE DAKOTA/MN BORDER. SOUTHERLY LOW LEVEL WINDS TO THE EAST OF THE
TROF COMBINED WITH VEERING/INCREASING WINDS WITH HEIGHT WILL PROVIDE
CONSIDERABLE VERTICAL SHEAR FOR A RISK OF A FEW SUPERCELLS THIS
AFTERNOON. AMBIENT LOW LEVEL VORTICITY AND STEEP LAPSE RATES WILL
ALSO AID IN THE RISK OF ISOLATED TORNADOES...ALONG WITH HAIL AND
DAMAGING WINDS. THIS THREAT SHOULD DIMINISH SHORTLY AFTER SUNSET.

...IA/PA/WV/KY...
MORNING WATER VAPOR IMAGERY SHOWS A STRONG MID LEVEL JET MAX MOVING
ACROSS IL. THIS FEATURE WILL TRACK INTO THE UPPER OH VALLEY BY THIS
AFTERNOON PROVIDING LARGE SCALE ASCENT AND AIDING IN THE DEVELOPMENT
OF SCATTERED THUNDERSTORMS. AMPLE MOISTURE/INSTABILITY WILL BE IN
PLACE ACROSS MUCH OF OH...WITH A RATHER STRONG THETA-E GRADIENT
ACROSS WESTERN PA INTO WV. FORECAST SOUNDINGS SHOW SUFFICIENT
VERTICAL SHEAR FOR A RISK OF ORGANIZED MULTICELL AND SCATTERED
SUPERCELL STORMS THIS AFTERNOON CAPABLE OF TORNADOES...LARGE
HAIL...AND DAMAGING WINDS. EASTWARD PROGRESS INTO CENTRAL PA AND
EASTERN WV WILL BE LIMITED BY WEAKER INSTABILITY IN THIS REGION.

...SOUTHEAST STATES...
RATHER STRONG NORTHWEST FLOW ALOFT IS PRESENT TODAY OVER THE
SOUTHEAST STATES. SCATTERED CLOUDS THIS MORNING WILL GIVE WAY TO
POCKETS OF STRONG HEATING THIS AFTERNOON...YIELDING MLCAPE VALUES
OVER 2000 J/KG IN MANY AREAS. SCATTERED THUNDERSTORMS ARE EXPECTED
TO INTENSIFY OVER MUCH OF THE REGION BY MID AFTERNOON AS CONVECTIVE
TEMPERATURE IS REACHED AND INITIATION OCCURS OVER THE HIGHER
TERRAIN. STORMS WILL TRACK SOUTHEASTWARD ACROSS THE RISK AREA WITH
A THREAT OF DAMAGING WINDS AND HAIL. WATER VAPOR IMAGERY SHOWS
MULTIPLE WEAK UPPER VORTICITY MAXIMA WHICH MAY HELP TO FOCUS STORMS
ACROSS THE REGION.

...WEST TX...
HOT CONDITIONS ARE EXPECTED THIS AFTERNOON OVER WEST TX WITH
TEMPERATURES OVER 100F AND LARGE SURFACE T-TD SPREADS. MODEL
GUIDANCE IS IN GOOD AGREEMENT IN DEVELOPING SCATTERED HIGH-BASED
SHOWERS AND THUNDERSTORMS ALONG AN AXIS FROM SOUTHWEST TX INTO THE
SOUTHERN PANHANDLE. INVERTED-V PROFILES AND SUFFICIENT CAPE WILL
PROMOTE A RISK OF LOCALLY DAMAGING WIND GUSTS IN THE STRONGEST
CORES.

PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0717 AM CDT WED JUN 17 2009

...SEVERE THUNDERSTORMS EXPECTED OVER PARTS OF THE CENTRAL PLAINS
LATER TODAY AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF...LARGE HAIL...DAMAGING WINDS AND A FEW TORNADOES
OVER PARTS OF THE CENTRAL PLAINS LATER TODAY AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

SOUTHWESTERN IOWA
EXTREME NORTHERN KANSAS
NORTHWEST MISSOURI
MUCH OF NEBRASKA

ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE FROM THE MID MISSISSIPPI
VALLEY INTO THE OHIO VALLEY AND INTO THE SOUTHEASTERN STATES.

A BELT OF STRONG UPPER LEVEL WINDS WILL STRETCH FROM AN UPPER TROUGH
OVER THE ROCKIES EASTWARD ACROSS THE CNTRL PLAINS AND INTO THE OHIO
VALLEY ATOP AN UPPER RIDGE. AT THE SAME TIME...A VERY WARM AND MOIST
AIR MASS WILL SPREAD NORTH AND EASTWARD. SEVERE STORMS WILL FIRE BY
LATE AFTERNOON ACROSS CENTRAL AND WESTERN NEBRASKA NEAR A WARM FRONT
AND NORTH OF A SURFACE LOW...WITH A THREAT OF VERY LARGE HAIL AND
ISOLATED TORNADOES. THIS ACTIVITY WILL THEN GROW INTO A LARGE
THUNDERSTORM COMPLEX CAPABLE OF PARTICULARLY DAMAGING WINDS IN
EXCESS OF 75 MPH AS IT QUICKLY TRAVELS EASTWARD ACROSS NEBRASKA AND
INTO IOWA AND NORTHERN MISSOURI LATER THIS EVENING.

ELSEWHERE...WIND SHEAR WILL ALSO BE FAVORABLE FOR SCATTERED SEVERE
STORMS OVER OHIO...WESTERN PENNSYLVANIA...AND NORTHERN WEST VIRGINIA
WITH A FEW TORNADOES POSSIBLE IN ADDITION TO DAMAGING WINDS AND
HAIL.

STATE AND LOCAL EMERGENCY MANAGERS ARE MONITORING THIS DEVELOPING
SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE
WEATHER SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA
WEATHER RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER
TODAY.
