Hail in Kansas, April 6, 2003

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
251 PM CDT SUN APR 6 2003

MAIN FCST CONCERN THIS PACKAGE IS CONVECTIVE ACTIVITY TNGHT,
ESPECIALLY OVER SE KS.

TNGHT: MUCH OF WHAT HAPPENS TNGHT WL REVOLVE AROUND HOW THE
CONVECTIVE ACTIVITY EVOLVES AROUND ZONE ISSUANCE TIME. AM EXPECTING
STORMS TO DEVELOP CLOSE TO OR JUST BEFORE ISSUANCE TIME, WITH SVR
STORMS DEFINITELY A THREAT OVER SE KS THIS EVENING. WIND PROFILES
ARE VERY IMPRESSIVE, WITH 60KTS AT 500MB AND 250MB WINDS AT 100KTS.
LOW LEVEL WINDS ARE ALSO EXPECTED TO BE BACKED OVER SE KS AHEAD OF
THE SFC LOW. THE MAIN QUESTION WL BE HOW FAR NORTH THE WARM
FRONT/BETTER MOISTURE MAKES IT. ATTM AM EXPECTING IT TO MAKE IT TO
BASICALLY ALONG THE KS/OK BORDER. THIS ACTIVITY SHUD BE SHORT LIVED
AS THIS STRONG SYSTEM LIFTS NORTH QUICKLY. PREV FCST HAD A MIX OF
SNOW AND RAIN TNGHT OVER CENTRAL KS, AND AM LEANING TOWARD TAKING IT
OUT, MAINLY DUE TO THE PRECIP CHANCES COMING BEFORE THE COLDER AIR
WORKS DOWN HERE. HAVE DECIDED TO GO WITH A MIX FOR THE FOUR CENTRAL
KS COUNTIES IN MY CWA, WITH NO ACCUMULATION EXPECTED AT ALL.

MON-WED: UPPER LOW WL GENERALLY BE SITUATED OVER NEBRASKA MON
BEFORE FINALLY SHEARING OUT AND MOVING EAST TUESDAY. SOUTH CENTRAL
AND SE KS SHUD SEE SOME SUN MONDAY WHICH MAY HELP TO BOOST TEMPS
INTO THE LOWER 50S. AS THIS SYSTEM PULLS OUT, COLDER CANADIAN AIR WL
SPILL DOWN INTO THE PLAINS. BY TUES 12Z 850MB TEMPS WL BE AROUND THE
-10 DEGREE RANGE, WHICH IS REALLY COLD FOR THIS TIME OF YEAR. SOME
LOW CLOUDS WL ALSO ACCOMPANY THE ARRIVAL OF THE COLDER AIR MONDAY
NGHT INTO TUESDAY, WHICH WL REALLY LIMIT HEATING TUES.  THEREFORE,
WENT BELOW FWC AND MORE IN LINE WITH THE MAV NUMBERS, WHICH MAY EVEN
BE TOO WARM. BUT FOR NOW WL JUST TREND IN THIS DIRECTION. BY WED SFC
RIDGE WL PLANT ITSELF OVER THE AREA, PROVIDING CLEARING SKIES. BUT
WITH FAIRLY COOL 850MB TEMPS STILL IN PLACE OVER SE KS, WL KNOCK
DOWN TEMPS WED, MORE IN LINE WITH 1000-850MB THICKNESSES, WHICH
PLACES MOST OF CWA IN THE 50S WITH AROUND 60 OVER CENTRAL KS.

THURS-SUN: NOT MUCH CHANGE NEEDED TO THE FCST THROUGH THIS PERIOD,
AS A GOOD WARM UP AND DRY CONDITIONS ARE STILL EXPECTED.

BY THURS WE WL BE UNDER NW FLOW ALOFT AS THE STRONG TROUGH AFFECTING
US NOW IS SITUATED OVER THE SE US. THEREFORE, LOOK FOR GENERALLY SW
SFC FLOW, WITH CLEAR AND WARMING CONDITIONS. BY 12Z FRI UPPER FLOW
SHUD FLATTEN OUT ALLOWING SOME LEE SIDE TROUGHING AND CONTINUING
WARMING TEMPS. HIGHS FRI ARE EXPECTED TO BE IN THE UPPER TO MID 70S
CWA WIDE, AS 850MB TEMPS CLIMB INTO THE 10 -14 DEGREE RANGE. IF WE
GET FULL SUN AND MIXING CENTRAL KS COULD EVEN CLIMB TO LOWER 80S.
THE ECM IS STILL TRYING TO PUSH A WEAK UPPER LOW ACROSS SOUTHERN
TEXAS. JUST LIKE YESTERDAYS RUNS, THE GFS IS NOT EVEN HINTING AT
THIS.  IF THE ECM WOULD VERIFY, THE ONLY CHANGE FROM THE GFS WOULD
BE MORE MID-UPPER CLOUDS OVER SOUTH CENTRAL KS FRI-SAT. BY SAT-SUN
MOST OF CENTRAL KS SHUD WARM INTO THE 80S, AS 850MB TEMPS STAY
FAIRLY WARM.
