SPC AC 251722
DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1222 PM CDT SUN MAY 25 2008
VALID 261200Z - 271200Z
...THERE IS A MDT RISK OF SVR TSTMS ACROSS PARTS OF CNTRL AND SRN
KS...
...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF THE SRN
PLAINS...CNTRL PLAINS...SRN HIGH PLAINS...MID MS VALLEY...OH VALLEY
AND NRN APPALACHIAN MTNS...
...SIGNIFICANT SEVERE WEATHER EVENT APPEARS LIKELY ACROSS CNTRL AND
SRN KS MONDAY AFTERNOON AND EVENING...
...CNTRL AND SRN PLAINS...
SOUTHWEST FLOW ACROSS THE CNTRL PLAINS TONIGHT WILL BECOME MORE
WESTERLY AS AN UPPER-LEVEL TROUGH IN THE NRN U.S. MOVES EWD INTO THE
GREAT LAKES REGION. IN THE WAKE OF THE TROUGH...AN UPPER-LEVEL RIDGE
WILL BUILD ACROSS THE GREAT PLAINS AS STRONG LOW-LEVEL FLOW
ASSOCIATED WITH A 40 TO 50 KT LOW-LEVEL JET REINFORCES MOISTURE
ACROSS A BROAD WARM SECTOR. MODERATE INSTABILITY IS FORECAST TO
DEVELOP FROM SRN KS ACROSS OK INTO THE OZARK REGION BY MONDAY
AFTERNOON. THIS COMBINED WITH THE LOW-LEVEL JET AND MODERATE TO
STRONG VERTICAL SHEAR SHOULD SUPPORT A WELL-ORGANIZED SEVERE MCS
ACROSS PARTS OF KS FROM LATE MONDAY AFTERNOON THROUGH MUCH OF THE
EVENING. FURTHER WEST...THUNDERSTORMS SHOULD ALSO INITIATE ALONG THE
DRYLINE IN WEST TX AND ON THE WEST EDGE OF THE INSTABILITY AXIS IN
ERN CO.
AT THE SFC...A 998 TO 1000 MB LOW IS FORECAST OVER SW KS MONDAY
AFTERNOON WITH A SHARP WARM FRONT EXTENDING EWD ACROSS CNTRL KS.
STRONG DIRECTIONAL SHEAR WILL EXIST ALONG AND NORTH OF THE BOUNDARY
WHICH WILL ENHANCE LOW-LEVEL SHEAR PROFILES. THE
INSTABILITY...VERTICAL SHEAR AND STRONG LOW-LEVEL SHEAR WILL SUPPORT
SUPERCELLS CAPABLE OF PRODUCING TORNADOES. A POTENTIAL FOR STRONG
TORNADOES SHOULD EXIST ESPECIALLY WITH SUPERCELLS THAT MOVE EWD
ALONG THE WARM FRONT WHERE 0-1 KM HELICITIES WILL BE LOCALLY
ENHANCED. SUPERCELLS WILL ALSO BE CAPABLE OF VERY LARGE HAIL DUE TO
A PLUME OF STEEP MID-LEVEL LAPSE RATES FROM THE SOUTHWEST AND
MODERATE TO STRONG INSTABILITY SOUTH OF THE WARM FRONT. THE THREAT
FOR LARGE HAIL WILL LIKELY EXTEND SWD ALONG THE DRYLINE INTO WEST TX
WITH ISOLATED VERY LARGE HAIL ALSO POSSIBLE THERE. FURTHER WEST
ACROSS ERN CO...A FEW SEVERE STORMS MAY ALSO DEVELOP WHERE STRONG
VERTICAL SHEAR WILL EXIST IN THE EXIT REGION OF AN APPROACHING 50 TO
60 KT MID-LEVEL JET.
THE MCS OVER KS SHOULD CONTINUE TO MOVE EWD ACROSS ERN KS INTO MO
DURING THE LATE EVENING AND OVERNIGHT PERIOD. VERTICAL SHEAR AND
INSTABILITY ON FORECAST SOUNDINGS SUGGEST THE ENVIRONMENT WILL
SUPPORT A SEVERE THREAT AFTER MIDNIGHT AND THE WIND DAMAGE POTENTIAL
COULD BECOME ENHANCED IF A LARGE BOWING SEGMENT CAN ORGANIZE ACROSS
ERN KS AND THE OZARK REGION.
...MID-MS VALLEY/OH VALLEY/ERN GREAT LAKES...
AN UPPER-LEVEL TROUGH WILL DEAMPLIFY AND BROADEN ACROSS THE GREAT
LAKES REGION TONIGHT THROUGH MONDAY. A SHORTWAVE TROUGH EMBEDDED IN
WLY FLOW IS FORECAST TO DRIFT EWD ACROSS THE MID TO UPPER MS-VALLEY
WITH A LOW-LEVEL JET MOVING EWD INTO THE OH VALLEY MONDAY AFTERNOON.
SEVERAL MCS CLUSTERS APPEAR LIKELY TO DEVELOP ACROSS THE REGION
ASSOCIATED WITH LIFT FROM THE LOW-LEVEL JET AND SHORTWAVE TROUGH.
MODEL FORECASTS DEVELOP MODERATE INSTABILITY ACROSS MOST OF THE
MID-MS AND OH VALLEYS WITH FORECAST SOUNDINGS SHOWING MODERATE
VERTICAL SHEAR PROFILES IN PLACE. ALTHOUGH SHEAR APPEARS TO BE ON
THE LOW-END FOR SUPERCELLS...A FEW SUPERCELLS MAY DEVELOP IN AREAS
WITH LOCALLY MAXIMIZED INSTABILITY. THE SHEAR AND THERMODYNAMIC
ENVIRONMENT LOOKS MORE FAVORABLE FOR SEVERE MULTICELL LINE SEGMENTS
WITH WIND DAMAGE POTENTIAL. AN AREA WITH ENHANCED WIND DAMAGE
POTENTIAL COULD DEVELOP IF INSTABILITY AND SHEAR PARAMETERS END UP
BEING A BIT STRONGER THAN CURRENTLY FORECAST.

I hope not, but time will tell.
Bust or otherwise, the SPC has and knows the data. We all know that sometimes weather "changes".
