URGENT - IMMEDIATE BROADCAST REQUESTED
TORNADO WATCH NUMBER 90
NWS STORM PREDICTION CENTER NORMAN OK
150 PM CDT WED APR 10 2013


Quote: THE NWS STORM PREDICTION CENTER HAS ISSUED A
TORNADO WATCH FOR PORTIONS OF

SOUTHERN ILLINOIS
SOUTH CENTRAL AND SOUTHEAST MISSOURI

EFFECTIVE THIS WEDNESDAY AFTERNOON AND EVENING FROM 150 PM UNTIL
900 PM CDT.

TORNADOES...HAIL TO 2.5 INCHES IN DIAMETER...THUNDERSTORM WIND
GUSTS TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE
AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 80 STATUTE
MILES EAST AND WEST OF A LINE FROM 25 MILES NORTHEAST OF SCOTT
AFB ILLINOIS TO 35 MILES EAST SOUTHEAST OF WEST PLAINS MISSOURI.
FOR A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU0).

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 88...WW 89...

DISCUSSION...SURFACE HEATING/DESTABILIZATION ACROSS SRN/ERN MO IS
CONTRIBUTING TO MODERATE INSTABILITY IN THE WARM SECTOR...WITH A
WEAKENING CAP AND INCREASING PROBABILITY FOR THUNDERSTORM INITIATION
IN THE NEXT COUPLE OF HOURS. GIVEN THE MODERATE INSTABILITY AND MID
60S BOUNDARY LAYER DEWPOINTS...AN INCREASE IN VERTICAL SHEAR
/ALREADY NOTED IN THE VWP FROM SAINT LOUIS/ WILL RESULT IN AN
INCREASING RISK FOR SUPERCELLS WITH TORNADOES AND LARGE HAIL. LATER
THIS AFTERNOON/EVENING...CONVECTION SHOULD EVOLVE INTO MORE OF A
LINE ALONG THE COLD FRONT IN MO...WITH A CONTINUED RISK FOR EMBEDDED
CIRCULATIONS AND DAMAGING WINDS.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE
WIND GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO
550. MEAN STORM MOTION VECTOR 23040.

MESOSCALE DISCUSSION 0430
NWS STORM PREDICTION CENTER NORMAN OK
0446 PM CDT WED APR 10 2013


Quote: AREAS AFFECTED...NORTHERN/CENTRAL LA INTO WESTERN MS

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 102146Z - 102345Z

PROBABILITY OF WATCH ISSUANCE...60 PERCENT

SUMMARY...NEAR/AHEAD OF A COLD FRONT...AT LEAST AN ISOLATED SEVERE
POTENTIAL MAY INCREASE THROUGH LATE AFTERNOON/EARLY EVENING ACROSS
PORTIONS OF NORTHERN/CENTRAL LA INTO WESTERN MS. THIS INCLUDES
POTENTIAL FOR DAMAGING THUNDERSTORM WINDS AND A TORNADO OR
TWO...MONITORING FOR A WATCH.

DISCUSSION...PER RECENT VISIBLE SATELLITE IMAGERY /SINCE
2045Z/...BOUNDARY LAYER CU FIELD WITHIN THE WARM SECTOR APPEARS TO
BE DEEPENING ESPECIALLY ACROSS NORTH-CENTRAL/NORTHEAST LA INTO FAR
SOUTHWEST MS...INCLUDING AREAS 50-75 MILES EITHER SIDE OF I-20. THIS
IS AHEAD A COLD FRONT WHICH EXTENDS SOUTH-SOUTHWESTWARD FROM A
WEST-CENTRAL AR SURFACE LOW TO NEAR THE SHREVEPORT AREA INTO EXTREME
EASTERN TX AS OF 21Z. WITHIN THE WARM SECTOR...BOUNDARY LAYER CINH
NOW APPEARS NEGLIGIBLE AMID LOWER 80S SURFACE TEMPERATURES AND UPPER
60S OR NEAR 70F SURFACE DEWPOINTS. AS SUCH...IT IS POSSIBLE THAT
WARM SECTOR TSTM DEVELOPMENT MAY CONTINUE TO OCCUR WITH ADDITIONAL
DESTABILIZATION...ESPECIALLY GIVEN GRADUAL HEIGHT FALLS/STRONG
DIFFLUENCE ON THE SOUTHERN PERIPHERAL OF A PLAINS UPPER TROUGH.
COINCIDENT WITH THE ENTRANCE REGION OF A MODERATELY STRONG SOUTHERLY
LOW LEVEL JET...LOW-LEVEL/DEEP LAYER WILL SUPPORT WARM SECTOR
SUPERCELLS AS UPDRAFTS CONTINUE TO MATURE...WITH A MORE LINEAR MODE
NEAR THE COLD FRONT. THUNDERSTORM WIND GUSTS AND PERHAPS A TORNADO
OR TWO WILL BE POSSIBLE THIS EVENING...AND INCREASING TRENDS MAY
PROMPT A WATCH ISSUANCE.
