Someone earlier in the thread asked about you when there was a report of hail and sheet metal in Monett.

PRE-FRONTAL SQUALL LINE ADVANCES EASTWARD AT AROUND 35 KTS. LINE
APPEARS LIKELY TO REACH THE CREST OF THE APPALACHIANS DURING THE
17-19Z TIME FRAME...UPON WHICH INFLOW OF COOL/DRY AND STABLE AIR
LIKELY WILL LEAD TO WEAKENING TRENDS. BOUNDARY LAYER AIR TO THE
WEST OF THE APPALACHIANS IS NOT PARTICULARLY UNSTABLE...BUT
DOWNSLOPE COMPONENT TO LOW-LEVEL FLOW IS ALLOWING FOR SURFACE
HEATING AHEAD OF STRONGLY FORCED CONVECTIVE LINE. AND...DAMAGING
WIND POTENTIAL COULD STILL INCREASE AS LOW-LEVEL LAPSE RATES
STEEPEN. HODOGRAPHS BENEATH A 50-60+ KT SOUTHERLY 850 MB JET CORE
ARE LARGE AND CLOCKWISE CURVED...SO THE TORNADO THREAT IS NOT
NEGLIGIBLE. HIGHEST POTENTIAL MAY BE NORTHEAST OF MORRISTOWN TN

Down to a slight risk...the big supercells have emerged in the Atlantic. The question mark now is whether anything can get going behind the line.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1101 AM CDT SUN MAY 11 2008
VALID 111630Z - 121200Z
...THERE IS A SLGT RISK OF SVR TSTMS OVER MUCH OF THE SOUTHEAST
STATES INTO THE UPPER OH VALLEY AND MID ATLANTIC REGION...
INTENSE UPPER LOW WILL MOVE FROM CENTRAL IND INTO VA DURING THIS
FORECAST PERIOD...WITH 80-100 KNOT MID LEVEL JET SURGING EASTWARD
ACROSS MUCH OF THE OH/TN VALLEYS AND EVENTUALLY INTO THE CAROLINAS.
THE DERECHO THAT AFFECTED PARTS OF THE SOUTHEAST STATES OVERNIGHT
HAS NOW MOVED OFFSHORE...BISECTING THE PRIMARY RISK ZONE TODAY INTO
TWO AREAS. ONE OVER SOUTHERN GA/NORTH FL...AND THE OTHER OVER PARTS
OF SC/NC. ALSO...ORGANIZED SEVERE STORMS ARE EXPECTED THROUGH MID
AFTERNOON OVER PARTS OF THE CENTRAL APPALACHIANS.
...SOUTHEAST GA/NORTHEAST FL...
CLUSTER OF THUNDERSTORMS CONTINUES TO MOVE EASTWARD AND OFF THE GA
COAST. MEANWHILE...ISOLATED CELLS CONTINUE TO SLOWLY INTENSIFY OVER
SOUTHERN GA AND FAR NORTH FL. THIS ACTIVITY IS IN A REGION OF
MODERATE INSTABILITY AND STRONG DEEP LAYER VERTICAL SHEAR.
THUNDERSTORMS IN THIS AREA TODAY WILL CONTINUE TO POSE A RISK OF
DAMAGING WINDS AND HAIL. THREAT FARTHER SOUTH IS MORE UNCERTAIN DUE
TO LIMITED LOW LEVEL CONVERGENCE AND FORCING TO INITIATE STORMS.
HOWEVER...A CONDITIONAL THREAT EXISTS WITH ANY STORMS THAT CAN FORM
DUE TO STRONG DAYTIME HEATING AND SEA BREEZE CONVERGENCE.
...WV/KY/VA/TN/WRN NC...
BAND OF STRONGLY FORCED THUNDERSTORMS IS ROTATING NORTHEASTWARD INTO
WESTERN WV AND EXTREME SOUTHWEST VA. THIS ACTIVITY IS ALONG LEADING
EDGE OF STRONG DPVA...AND IS EXPECTED TO PERSIST FOR AT LEAST
ANOTHER COUPLE OF HOURS BEFORE WEAKENING AS IT CROSSES THE
APPALACHIANS. SOME MODEL GUIDANCE SUGGESTS THAT ACTIVITY MAY
MAINTAIN INTENSITY OVER WESTERN/CENTRAL VA THIS AFTERNOON WITH A
CONTINUED THREAT OF DAMAGING WINDS.
...SC/NC...
VISIBLE SATELLITE IMAGERY SHOWS RAPID CLEARING ALONG AND SOUTH OF
REMNANT SURFACE WARM FRONT EXTENDING FROM EAST OF ATL INTO CENTRAL
SC. DENSE LOW CLOUDS AND EASTERLY SURFACE WINDS ARE MAINTAINING A
MORE STABLE AIRMASS NORTH OF BOUNDARY. PRESENT TRENDS AND MODEL
GUIDANCE SUGGEST THAT BOUNDARY MAY LIFT SLIGHTLY NORTHWARD THIS
AFTERNOON...ESPECIALLY OVER EASTERN SC/NC. THIS WILL RESULT IN
RATHER RAPID DESTABILIZATION OF THE AIR MASS ROUGHLY ALONG AN AXIS
FROM CAE-FAY-HAT. FORCING ASSOCIATED WITH UPPER JET WILL OVERSPREAD
THIS REGION THIS AFTERNOON...LIKELY LEADING TO SCATTERED
THUNDERSTORM DEVELOPMENT. FORECAST SOUNDINGS SHOW RELATIVELY STEEP
MID LEVEL LAPSE RATES AND IMPRESSIVE VERTICAL SHEAR PROFILES ALONG
THE BOUNDARY. STORMS THAT TRACK ALONG THE BAROCLINIC ZONE WITH POSE
A THREAT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS.

LARGE-SCALE FLOW...TO THE SOUTH OF A 90-100 KT 500 MB POLAR JET

NWS STORM PREDICTION CENTER NORMAN OK
210 PM EDT SUN MAY 11 2008
THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF
NORTH CAROLINA
NORTHERN SOUTH CAROLINA
SOUTHERN VIRGINIA
EFFECTIVE THIS SUNDAY AFTERNOON AND EVENING FROM 210 PM UNTIL 800
PM EDT.
TORNADOES...HAIL TO 1.5 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 80 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
AREAS.
THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 85 STATUTE
MILES EAST AND WEST OF A LINE FROM 55 MILES NORTH NORTHEAST OF
SOUTH HILL VIRGINIA TO 75 MILES SOUTH SOUTHEAST OF CHARLOTTE
NORTH CAROLINA. FOR A COMPLETE DEPICTION OF THE WATCH SEE THE
ASSOCIATED WATCH OUTLINE UPDATE (WOUS64 KWNS WOU7).
REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.
OTHER WATCH INFORMATION...CONTINUE...WW 306...
DISCUSSION...STRONGLY FORCED PRE-FRONTAL SQUALL LINE HAS PASSED THE
CREST OF THE APPALACHIANS AND WAS RECONSOLIDATING ACROSS THE VA/NC
FOOTHILLS ATTM. AIR MASS AHEAD OF THE BROKEN CONVECTIVE LINE WAS
ONLY WEAKLY UNSTABLE BASED ON OBJECTIVE DATA. HOWEVER...BINOVC AND
MOISTENING ON LOW LEVEL ESELY FLOW WILL CONTRIBUTE TO CONTINUING
DESTABILIZATION AS THE INTENSE FORCING WITH THE UPPER TROUGH AND
100KT 500MB WIND MAX SPREAD EAST. IN ADDITION TO RAPID STORM MOTION
AND WIND DAMAGE THREAT...BRIEF TORNADOES APPEAR POSSIBLE AS STRONG

ONLY WEAKLY UNSTABLE BASED ON OBJECTIVE DATA. HOWEVER...BINOVC AND
MOISTENING ON LOW LEVEL ESELY FLOW WILL CONTRIBUTE TO CONTINUING
DESTABILIZATION AS THE INTENSE FORCING WITH THE UPPER TROUGH AND

AREAS AFFECTED...PARTS OF ERN OH...WV...SW VA...ERN TN
CONCERNING...TORNADO WATCH 306...307...
VALID 111833Z - 111930Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 306...307...CONTINUES.
BUT...THE SEVERE THREAT IS DIMINISHING/BECOMING MORE LOCALIZED.
AND...A NEW WW IS NOT ANTICIPATED.
THE LEADING EDGE OF LOW-LEVEL COLD ADVECTION ACROSS THE LOWER OHIO
VALLEY CONTINUES TO GRADUALLY ADVANCE TOWARD THE CREST OF THE
NORTHERN/CENTRAL APPALACHIANS. AND...THIS WILL EVENTUALLY END
CONVECTIVE POTENTIAL ALONG ITS WESTERN SLOPES FROM EXTREME NORTHEAST
TENNESSEE INTO EASTERN OHIO. HOWEVER...THE NARROWING TONGUE OF WEAK
BOUNDARY LAYER INSTABILITY WITHIN CLEAR SLOT EAST OF THE MID-LEVEL
CIRCULATION MAY REMAIN A FOCUS FOR A FEW STORMS THROUGH 20-21Z. ONE
OR TWO OF THESE MAY STILL BE CAPABLE OF PRODUCING A BRIEF TORNADO OR
SOME MARGINALLY SEVERE HAIL IN THE PRESENCE OF FAVORABLE SHEAR AND
AMBIENT VERTICAL VORTICITY. BUT...THE OVERALL SEVERE THREAT IS
BECOMING LOW.
