NATIONAL WEATHER SERVICE SIOUX FALLS SD
952 PM CDT TUE MAY 7 2002

02Z SUBJECTIVE SURFACE ANALYSIS INDICATED PRIMARY AREA OF LOW
PRESSURE OVER SOUTHEAST COLORADO. WARM FRONT HAS SURGED NORTH AND
WAS LOCATED FROM NEAR NORFOLK, NEB EAST TO SIOUX CITY, IA AND THEN
SOUTHEAST INTO CENTRAL IOWA. MOISTURE RETURN HAS BEEN FAIRLY
IMPRESSIVE WITH THE 60 DEGREE ISODROSOTHERM INTO SOUTHERN ZONES OF
CWA. LOOKING AT THE 00Z SOUNDING FROM OMAHA AND LIFTING A PARCEL
FROM 800MB WOULD YIELD OVER 1500J/KG OF ELEVATED INSTABILITY.

INITIAL WAVE OF SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE TO
THE NORTH AND EAST. ACTIVITY IS NOW FAR ENOUGH NORTH AND EAST OF THE
ELEVATED INSTABILITY THAT SEVERE POTENTIAL FAIRLY LOW. AN ADDITIONAL
WAVE IS INDICATED OVER CENTRAL CO ON THE LATEST WATER VAPOR
IMAGERY. LATEST SHORT-RANGE MODELS INDICATE THIS WAVE TO MOVE TO THE

INSTABILITY...THUNDERSTORMS WILL LIKELY ONCE AGAIN DEVELOP OVER
CENTRAL AND NORTHERN NEB AFTER 06Z. THE THUNDERSTORMS WILL THEN MOVE
TO THE NORTHEAST ACROSS SOUTHEAST SD/NORTHEAST NEB/NORTHWEST IA. WE
HAVE SEVERE WORDING IN THE ZONES...AND FEEL A CONTINUED HAIL THREAT
IS THERE...SO WE WILL CONTINUE SEVERE WORDING IN THE SOUTHERN CWFA.
PRIMARY AREA FOR SEVERE WILL BE IN NORTHEAST NEB/FAR SOUTHEAST
SD/NORTHEAST IOWA WHERE BETTER INSTABILITY AND SHEAR COME TOGETHER.

OTHERWISE ZONES APPEAR TO BE IN GOOD SHAPE WITH ONLY MINOR CHANGES
BEING MADE. WILL TAKE OUT THE BECOMING WORKING IN THE NORTHWEST
ZONES FOR WIND AND TWEAK SOME TEMPERATURES IN THE CENTRAL AND
SOUTHERN ZONES WHERE THE WARM FRONT HAS SURGED NORTH.
