Severe Thunderstorm Warning 162, NWS Wichita, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
215 PM CDT SUN JUN 3 2001

MAIN CONCERN THIS PACKAGE IS CHANCE OF STORMS THIS EVENING.  OUTFLOW
FROM STORMS EARLY THIS MORNING PUSHED INTO NORTHERN OK...SOUTH OF
THE WARM FRONT EXTENDING ALONG THE KS/OK BORDER.  SFC WINDS HAVE
RECOVERED ACROSS OK AND HAVE RETURNED TO SOUTHERLY...PUMPING +70F
DEWPTS AND +90F TEMPS INTO NORTH CENTRAL OK.  CAPES ARE RUNNING
AROUND 6000 J/KG ACROSS OK WITH 0-1KM HELICITY AT 100-400M/S ALONG
THE WARM FRONT. READINGS NORTH OF THE FRONT HAVE REMAINED IN THE 60S
WITH MID 50S DEWPTS.  ALSO OF NOTE IS A WAVE COMING OUT OF THE
ROCKIES AND CURRENTLY MOVING ACROSS ERN CO AND ERN NM. THE MAIN
NEGATIVE FACTOR IS THE STRENGTH OF THE MID LEVEL CAP WHICH IS
RUNNING +12C TO +15C. HOWEVER...FRONT IS BECOMING SO DEFINED THIS
AFTERNOON IT APPEARS SOME STORMS WILL BE ABLE TO GET GOING ALONG THE
SOUTHERN BORDER LATE THIS AFTERNOON. ALTHOUGH THE TORNADIC THREAT
WILL REMAIN NEAR THE KS/OK BORDER...LARGE HAIL WILL BE A CONCERN FOR
AREAS ALONG U.S. HWY 54 AND NORTHWARD. NEXT QUESTION IS HOW WILL THE
STORMS WHICH GET GOING THIS EVENING AFFECT THE PRECIP WHICH WAS
EXPECTED TO DEVELOP IN THE WWA LATER TONIGHT NORTH OF THE WARM
FRONT.  STILL SUSPECT THAT WITH THE EAST-WEST BOUNDARY REMAINING
NEAR THE KS/OK BORDER AND 850MB DEWPTS POOLING IN THE MID TEENS OVER
THE AREA...STORMS WILL DEVELOP ACROSS CEN/ERN KS DURING THE
OVERNIGHT HOURS ONCE THE LLJ KICKS IN AT SPEEDS OF 40-55KTS.  DUE TO
HEAVY RAINS THE PAST FEW DAYS ACROSS THE REGION...AND WITH MORE
HEAVY RAINS EXPECTED TONIGHT WILL GO AHEAD WITH A FLASH FLOOD WATCH
FOR MOST OF THE AREA.

SFC LOW IS EXPECTED TO REMAIN NEAR THE OK PANHANDLE THROUGH TUESDAY
MORNING WITH THE WARM FRONT GRADUALLY PUSHING NORTH ACROSS ERN KS
AND MOST OF MISSOURI.  HOWEVER WITH THE BOUNDARY STILL SLICING
ACROSS THE CWA AND THE UPPER LEVEL FLOW BECOMING NEARLY ZONAL WITH
SEVERAL EMBEDDED SHORTWAVES...WILL KEEP A CHC OF PRECIP IN THE
FORECAST THROUGH TUE NIGHT.

EXTENDED...
SFC HIGH PRESSURE FINALLY BUILDS INTO THE AREA ON WED AND PERSISTS
INTO FRI BEFORE SLIDING OFF TO THE EAST. WILL CONTINUE TO KEEP
FORECAST DRY FOR THE LATTER HALF OF THE WEEK...AS THE UPPER LEVEL
RIDGE BEGINS TO SLIDES OVERHEAD.  BY NEXT WEEKEND...WITH THE RETURN
OF SOUTHERLY FLOW AND THE UPPER LEVEL RIDGE CONTINUING TO SHIFT
EAST...WILL ADD A CHANCE OF -TSRA TO LATE SAT AND INTO SUNDAY.
AS FOR TEMPS...A GRADUAL WARMING TREND THROUGH THE WEEK.
