Tornadoes and Hail in Kansas, April 19, 2003

AREA WEATHER SUMMARY
NATIONAL WEATHER SERVICE WICHITA KS
200 PM CDT SAT APR 19 2003

OVERALL...GOING FCST IS IN GOOD SHAPE. ONLY MINOR TWEAKS NEEDED
ALONG WITH A FEW ADJUSTMENTS HERE AND THERE. WL PLAN ON ISSUING
FORECAST PACKAGE EALIER TODAY DUE TO THE IMMINENT SEVERE WEATHER
THREAT FOR PARTS OF THE CWA.

NUMEROUS BOUNDARIES IN AND NEAR THE CWA WILL MAKE FOR A DIFFICULT
CONVECTION FORECAST FOR LATER THIS AFTERNOON AND EVENING. ANOTHER
COMPLICATING FACTOR IS THE VARYING AMOUNTS OF INSOLATION ACROSS THE
CWA. ALL IN ALL...SFC MOISTURE IS SLOWLY INCREASING ACROSS THE VERY
SRN PART OF THE CWA...AND THE WINDS ARE BACKED AROUND TO THE SE. NO
DOUBT THAT THERE IS ENOUGH SHEAR FOR SUPERCELLS TODAY (APPROX
50-70KTS 0-6KM). INSOLATION IN SRN KS HAS BECOME WEAK AT
BEST...LIMITING SFC BASED INSTABILITY.  HOWEVER...STORMS SHUD DEVLOP
IN MORE UNSTABLE AREAS OF OK AND MOVE RAPIDLY N AND NEWD INTO THE
SRN SXNS OF MY CWA AND RESPOND TO THE GOOD LOW LEVEL SHEAR AS WELL
AS THE LOW LCL HEIGHTS. STORMS MAY ALSO BE OF THE LOW TOPPED VARIETY
IN THIS SLIGHTLY COOLER AIRMASS UP HERE...BUT NO DOUBT WILL BE
POTENT...I.E...PRODUCING LARGE HAIL AND POSSIBLY TORNADOES. SEVERE
WEATHER THREAT WILL LIKELY SHIFT FURTHER EWD INTO SERN KS LATER THIS
EVENING. WILL ALSO BE ON THE LOOKOUT FOR LOCALIZED FLASH FLOOD
POTENTIAL...ESP IF STORMS CAN TRAIN & PROPAGATE ALONG BOUNDARIES.

STORMS WILL DIMINISH OVERNIGHT AND MOVE EWD WITH THE DEPARTING
SYSTEM. WL KEEP POPS GOING OVERNIGHT...ESP FOR S-CNTRL AND SERN
ZONES. AS IMPLIED EALIER...SOME STORMS WILL BE SEVERE...ESP EARLY
ON.

NO BIG CHANGES TO THE REST OF THE FORECAST...AS GOING FORECAST
MATCHES NICELY WITH LATEST MODEL RUNS. NEXT SIG SYSTEM LOOKS TO MOVE
INTO THE AREA SOMETIME WED AND THURS WITH THE CHC OF TSTMS...AND
CURRENT FCST HANDLES THIS WELL.

GRIDS/ZONES TO FLY BY 215...
