AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
338 PM CDT WED JUN 02 1999

MAIN CHALLENGE THIS FORECAST IS TIMING OF NEXT SHORT WAVE AND
RESULTANT SEVERE WEATHER IN WESTERN THIRD OF AREA.

20Z SFC CHART SHOWING 60+ DEW POINTS PUNCHING UP INTO LBL
AREA...WITH 70+ DEW POINTS ABOUT 100 MILES UPSTREAM IN WEST-CENTRAL
OKLAHOMA AND TEXAS PANHANDLE.  FEW TCU POPPED AROUND 1945Z IN
STEVENS...GRANT AND HASKELL COUNTIES...SO CONVECTIVE TEMPS HAD
BEEN REACHED.  THINK AS UPPER 100+ JET AT 3H OVER NEW MEXICO EJECTS
NORTHEASTWARD...SEVERE STORMS WILL FIRE IN NE NEW MEX AND TX PNHNDL
FIRST...AND EDGE NORTHWARD INTO SOUTHWEST KANSAS AS UPPER FLOW
BRINGS MORE LIFT NORTHEASTWARD.

MODIFIED 18Z SOUNDING AT DDC SHOWED LI OF -7 AND KI OF 30 BY
00Z...CAPE OF 2500 AND 0-2KM HELICITY OF 45.  FZL LEVEL HAD RAISED
SINCE 2/12Z FROM 12700 TO 13800 FEET AT 18Z.  THUS...LOWER LAYERS OF
ATMOSPHERE HAVE BECOME INCREASINGLY MORE UNSTABLE.  FRONTAL BOUNDARY
IS MOVING NORTH THROUGH NORTHERN OKLAHOMA AT 20Z...AND WILL SERVE AS
FOCUS BOUNDARY FOR STORMS THIS EVENING.  THINK THE GREATEST
THREAT WILL BE HAIL AND DOWNBURST OUTFLOW WINDS.  AFTER 5H/3H JET
GETS OVERHEAD ABOUT 03-05Z...THINK THERE WILL BE A MORE FAVORABLE
SHEAR ENVIRONMENT FOR MESOCYCLONES AND POSSIBLE TORNADOES.  AGREE
WITH SPC ON MOD RISK IN SW KANSAS.

FOR TEMPS...STAYED CLOSE TO FWC/FAN GUIDANCE AS THEY WERE CLOSE AND
LOOKED REASONABLE.

EXTENDED DISCUSSION...
LATEST CONCERN FOR THE WEEKEND SEVERE POTENTIAL IS THE SPEED OF THE
NEXT UPPER LOW FORECAST TO CROSS THE WESTERN HIGH PLAINS INTO
SUNDAY. IF ONE BUYS THE CANADIAN...THEN THE SEVERE POTENTIAL WOULD
EXIST TO THE CWA'S EAST WITH MOST OF THE CWA BEHIND THE DRYLINE.
HOWEVER...THE SLOWER MRF WOULD SUGGEST A GREATER POTENTIAL FOR
SEVERE. ATTM...WILL LEAVE IN THE SLIGHT CHC FOR THE WEEKEND. TEMPS
THROUGHOUT THE EXTENDED PERIOD WILL BE ABOVE NORMAL.

PRELIMINARY GUIDANCE FOR COORDINATION ONLY. OFFICIAL FORECASTS ARE
CONTAINED WITHIN THE DODGE CITY ZONE FORECAST.
