Severe Thunderstorm Warning 30, NWS Wichita, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
337 PM CDT TUE APR 15 2003

THE MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE THE CHANCES OF
SEVERE WEATHER TONIGHT, WITH MORE POSSIBLE ON FRIDAY INTO SATURDAY.

LATEST SURFACE OBSERVATIONS INDICATE THE DRY LINE IS ORGANIZING
ACROSS WEST CENTRAL KANSAS.  ALTHOUGH ELEVATED LIGHT RAIN SHOWERS
ARE BREAKING OUT, A SUBSTANTIAL CAP WILL REMAIN IN PLACE UNTIL
EVENING TO PREVENT ANY SURFACE BASED STORMS IN OUR AREA.  ALTHOUGH
SURFACE MOISTURE IS SHALLOW, A VERY STRONG LOW PRESSURE WILL PUSH
INTO NORTHWEST KANSAS.  THIS WILL SEND THE DRYLINE SURGING INTO
CENTRAL KANSAS THIS EVENING.  VERY COLD TEMPERATURES WILL QUICKLY
GET RID OF THE CAP.  SURFACE WINDS ARE PROGGED TO BACK EAST OF THE
DRYLINE TOWARD EVENING.  WINDS ALOFT ARE VERY STRONG, AS 70 TO 80
KNOTS IS PROGGED AT 500 MB AT 02Z.  THEREFORE, EXPECT SUPERCELL
THUNDERSTORMS TO RAPIDLY DEVELOP ON THE DRYLINE, AND MOVE QUICKLY
NORTH NORTH NORTHEAST AT 45 TO 60 MPH WITH SUCH STRONG WINDS ALOFT.
OBVIOUSLY,  A FEW TORNADOES WILL BE POSSIBLE ON THE DRYLINE WITH
SUCH WIND SHEAR.  THIS AREA WOULD BE MAINLY TO THE WEST OF THE
KANSAS TURNPIKE.  THEREAFTER, WITH SUCH STRONG LINEAR FORCING, A
SQUALL LINE WILL DEVELOP, WITH STRONG DAMAGING WINDS THE PRIMARY
THREAT.  WILL ALSO CONTINUE THE WIND ADVISORY THROUGH TONIGHT.

FOR TOMORROW THE PRIMARY THREAT WILL SWITCH TO VERY STRONG WINDS.
AS THE LOW MOVES EASTWARD INTO NORTHEAST KANSAS, STRONG WEST TO
NORTH WEST WINDS WILL WRAP AROUND THE DEEP LOW PRESSURE SYSTEM.
WILL SEE WIND GUSTS TO AROUND 50 MPH.  ALSO, MAY SEE SOME WIDELY TO
SCATTERED LIGHT RAIN SHOWERS WRAP AROUND THE STORM SYSTEM.

COOLER AIR WILL COME INTO THE REGION WEDNESDAY NIGHT.  EXPECT LOWS
TO DROP INTO THE 30S TO LOWER 40S.  A RATHER SEASONABLE AFTERNOON
WILL BE SEEN ACROSS THE AREA ON THURSDAY.  HOWEVER MAY SEE SOME
ELEVATED THUNDERSTORMS DEVELOP VERY LATE THURSDAY NIGHT, AS MOISTURE
RETURNS.

THE NEXT POTENT UPPER LEVEL DISTURBANCE WILL MOVE OFF THE PACIFIC
OCEAN.  ANOTHER STRONG DRYLINE WILL SETUP ACROSS THE REGION ON
FRIDAY.  THE POTENTIAL FOR MORE SEVERE WEATHER WILL EXIST, AND WINDS
ALOFT WILL ONCE AGAIN BE VERY STRONG.  JUST DEPENDS ON HOW DEEP THE
SURFACE MOISTURE WILL BE.  POTENTIAL FOR MORE SEVERE WEATHER ON
SATURDAY ACROSS EASTERN KANSAS, IF THE SLOWER ECMWF VERIFIES.
THEREAFTER, DRY AND SEASONABLE WEATHER IS EXPECTED FOR THE NEXT FEW
DAYS.
