Severe Thunderstorm Warning 198, NWS Wichita, KS

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
319 PM CDT MON JUN 29 1998

...SHORT TERM...
MAIN FCST PROBLEMS THIS AFTERNOON WILL BE THE FROPA TIMING AND MENTION
OF TSRA.  PRECIP EARLIER TODAY ACRS CWA HAS DISSIPATED WITH ONLY ECHOES
WELL TO THE NORTHEAST.  FRONT FCST TO MOVE THROUGH OVERNIGHT AND SHOULD
BE MOSTLY OUT OF CWA BY 24 HRS.  MODELS SHOWING DECENT LIFT ASSOCIATED
WITH FRONT AND CONVECTION ALREADY FIRING OVER ERN COLO.  WL HAVE MENTION
OF TSRA FOR ALL OF CWA OVERNIGHT BUT THINK BRUNT OF ACTIVITY SHOULD
STAY ACRS NRN PORTION. TEMPS NOT ALL THAT COOL OVERNIGHT AS BEST COOL
AIR WELL TO THE NORTH. WL GENERALLY GO ABV GUID NUMBERS BY A FEW
DEGREES.  WL ALSO LET HEAT ADVISORY EXPIRE THIS EVENING AS MAJORITY OF
AREA WILL DROP BELOW CRITERIA OVERNIGHT.  WL ISSUE NPW FOR HEAT AND
HANDLE REMAINING 4 HOURS WITH STF.

...LONG TERM...
MAIN PROBLEM WITH THIS PACKAGE WILL BE THE CHANCES FOR PRECIPITATION.

I WILL FOLLOW THE ETA/AVN SOLUTION DUE TO THE HANDLING OF THE
SURFACE FRONT.  THE FRONT IS PROGGED TO DROP SOUTH AND ALIGN ITSELF
ALONG THE OK/KS BORDER BY MORNING AND THEN FLUTTER AROUND NORTH
CENTRAL OKLAHOMA THROUGH F48.  THIS SCENARIO WILL FILTER IN SOME
COOLER TEMPERATURES THAN WHAT HAS PREVAILED THE PAST WEEK.  THE
READINGS LOOK TO BE SOMEWHERE AROUND NORMAL FOR THIS TIME OF YEAR.
THE PRESENCE OF A BOUNDARY WILL GIVE THE CWA...PRIMARILY THE
SOUTHERN HALF...A CHANCE FOR THUNDER THROUGH THE PERIOD.  THE BETTER
CHANCES WILL OCCUR TUESDAY NIGHT WHEN THE BEST INSTABILITY AND
MOISTURE FLUX IS PRESENT.  INITIAL THINKING IS THAT A FEW ISOLATED
THUNDERSTORMS WILL FIRE DURING THE AFTERNOON HOURS AND THEN DEVELOP
INTO AN MCS OVERNIGHT.

...EXTENDED...
I WILL ADD A CHANCE FOR THUNDER TO THE EXTENDED DUE TO THE LINGERING
SURFACE BOUNDARY JUST TO THE SOUTH.  THE TEMPERATURES SHOULD ALSO
REBOUND A BIT...BUT REMAIN BELOW WHAT HAS OCCURRED THE PAST WEEK.
