AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1051 PM CDT TUE MAY 24 2011
.UPDATE...
/626 PM CDT TUE MAY 24 2011/
HAVE REMOVED ADDITIONAL COUNTIES FROM THE SEVERE THUNDERSTORM
WATCH AS THE LINE CONTINUES TO DIMINISH IN INTENSITY. MLCAPES
CONTINUE TO RISE IN THE REMAINDER OF THE WATCH AREA...SO WILL
KEEP THE REST OF THE COUNTIES IN IT FOR NOW.
RECENT RUNS OF THE RUC ARE SHOWING THAT INSTABILITY INCREASES
ACROSS MO/IL AHEAD OF LINE OF STORMS OVER THE CENTRAL AND
SOUTHERN PLAINS. STILL LOOKS LIKE THE POTENTIAL FOR SEVERE
WEATHER WILL CONTINUE LATE THIS EVENING AND OVERNIGHT AS THIS
LINE CONTINUES TO MOVE NORTHEAST TOWARD THE CWA.

.DISCUSSION...
/306 PM CDT TUE MAY 24 2011/
...POTENTIAL INCREASING FOR SIGNIFICANT OUTBREAK OF SEVERE
THUNDERSTORMS WITH FLASH FLOODING OVER THE NEXT 24-36 HOURS...
SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED IN ADVANCE OF FORWARD
PROPAGATING MCS CURRENTLY OVER WEST CENTRAL MO. WHILE THERE HAVE
NOT BEEN ANY RECENT SEVERE WEATHER REPORTS...EXPECT POTENTIAL TO
INCREASE OVER THE AREA AS SURFACE DEWPOINTS INCREASE UNDER FULL
SUNSHINE RESULTING IN THE MLCAPES INCREASING TO 1500-2000 J/KG BY
00Z. THERE IS ALSO A WEAK BOUNDARY SEEN IN THE VISIBLE SATELLITE
IMAGERY MOVING NORTHEAST OVER SOUTHERN MO WHICH MAY AID IN INCREASING
SEVERE THREAT THIS AFTERNOON INTO EARLY THIS EVENING.
GFS/NAM/HRRR ARE ALSO INDICATING THAT LINE OF SIGNIFICANT SUPERCELLS
OVER THE CENTRAL PLAINS SHOULD CONGEAL INTO A FORWARD PROPAGATING
MCS THAT WILL MOVE ACROSS THE CWA OVERNIGHT. THIS LINE WILL LIKELY
ALSO BE SEVERE BECAUSE OF INCREASING SHEAR AND ASCENT AHEAD OF THE
UPPER CLOSED LOW IN ADDITION TO STRONG LOW LEVEL MOISTURE
TRANSPORT FROM THE GULF. THIS ROUND WILL LIKELY MOVE QUICKLY OUT
OF THE AREA TOMORROW MORNING ALLOWING FOR A PERIOD OF DRY TIME
FROM LATE MORNING INTO AFTERNOON.
THE POTENTIAL FOR SIGNIFICANT OUTBREAK OF SEVERE THUNDERSTORMS
INCLUDING TORNADOES IS INCREASING FOR TOMORROW AFTERNOON AND
EVENING AS THE AFOREMENTIONED DRY TIME TOMORROW SHOULD ALLOW FOR
THE ATMOSPHERE TO RECOVER FROM TONIGHT'S ACTIVITY. VERY STEEP
LAPSE RATES WILL MOVE IN AROUND THE SOUTH PART OF THE CLOSED LOW
AS UPPER 60 DEWPOINTS SURGE NORTH INTO AREA YIELDING MLCAPES
BETWEEN 2000-3500 J/KG. ASCENT FROM UPPER LOW WILL INCREASE
OVER ATTENDANT COLD FRONT/DRY LINE WHICH SHOULD CAUSE A RAPID
DEVELOPMENT OF SUPERCELLS ALONG AND SOUTH OF INTERSTATE 70 AFTER 3
PM. LOW LEVEL SHEAR WILL BE SUFFICIENT FOR TORNADOES...POSSIBLY
STRONG...AS WELL AS VERY LARGE HAIL AND DAMAGING WINDS. THIS ROUND
OF SEVERE WEATHER SHOULD MOVE OUT OF THE AREA BY MIDNIGHT TOMORROW
NIGHT.
IN ADDITION...I HAVE ISSUED A FLASH FLOOD WATCH FOR THE ENTIRE CWA
UNTIL 06Z TOMORROW NIGHT. WE HAVE ALREADY HAD SOME AREAS WITH
HEAVY RAINFALL THE PAST THREE DAYS...AND DO EXPECT THAT THE THREE
ROUNDS OF THUNDERSTORMS MENTIONED ABOVE WILL POSE AN INCREASING
THREAT FOR AT LEAST A FEW AREAS TO SEE FLASH FLOODING...ESPECIALLY
WHERE THERE IS ANY TRAINING.
AFTER THIS STORM SYSTEM MOVES OFF...THERE WILL BE SOME BRIEF DRY
TIME BEFORE ADDITIONAL ROUND OF THUNDERSTORMS COMES FRIDAY NIGHT.
PATTERN WILL THEN CHANGE WITH RIDGE BUILDING OVER THE EASTERN
CONUS. HAVE GONE DRY WITH TEMPERATURES CLIMB ABOVE NORMAL INTO
EARLY NEXT WEEK.

.AVIATION...
/1032 PM CDT TUE MAY 24 2011/
LARGE THUNDERSTORM COMPLEX OVER WRN MO WILL TRANSLATE EWD LATE TGT
THROUGH THE TAF SITES. SLY LOW LEVEL JET OF 50 TO 60 KTS WILL
ALSO TRANSLATE EWD THROUGH THE SRN HALF OF MO WITH LLWS MOST
LIKELY AT KCOU LATE TGT SINCE IT WILL BE CLOSEST TO THE JET AXIS.
STG AND GUSTY SLY SFC WINDS CAN BE EXPECTED ON WED. ANOTHER ROUND
OF THUNDERSTORMS...LIKELY SEVERE IS EXPECTED WED AFTN AND EVNG AS
AN UPPER LEVEL LOW AND ASSOCIATED SFC LOW MOVE EWD THROUGH NRN MO
DRAGGING A TRAILING CDFNT THROUGH THE AREA.
SPECIFICS FOR KSTL...TSRA OVER WRN MO WILL MOVE INTO STL AREA
AROUND 08Z WED AND CONTINUE UNTIL ABOUT 11Z WED. MODELS SUGGEST
THAT THERE MAY BE SOME MVFR CIGS ON WED BUT SIMILAR PROGS
YESTERDAY DID NOT VERIFY EVEN AFTER ABUNDANT RAINFALL DURING THE
DAY. ANOTHER ROUND OF THUNDERSTORMS...LIKELY SEVERE IS EXPECTED
LATE WED AFTN AND EVNG. SELY SFC WINDS SHOULD BECOME SLY WED MRNG
AND STRONG AND GUSTY DUE TO MIXING OF STRONG LOW LEVEL WINDS TO
THE SFC. THE SFC WIND WILL VEER AROUND TO A SWLY DIRECTION WED
EVNG AS A CDFNT MOVES EWD THROUGH THE AREA.
