AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DODGE CITY KS
317 PM CDT SAT AUG 01 1998

QUESTION FOR TNGT IS WHERE AND HOW MUCH CONVECTION THERE WILL BE.
UA ANLYS THIS MRNG SHOWED A GOOD BAROCLINIC ZONE AT H85 OVR THE
OK/NRN TX PANHANDLES EXTENDING EAST ACRSS NRN OKLA.  HIGHER DWPTS
HAVE BEEN POOLING ALNG AND NORTH OF THIS BNDRY.  FURTHER UP A PESKY
WK VORT MAX HAS BEEN HANGING AROUND SWRN KS ALL DAY PER THE PROFILER
PLAN VIEW AT H5.  THIS ALL SHOWING UP WELL IN SAT IMGRY AS WELL AS A
BAND OF -SHRA OCCURNG ALONG THE BAROCLNIC ZONE.  SOME BREAKS IN THE
CLDS HAVE ALLOWED LWR LVLS TO WARM UP.

ETA MODEL SEEMED TO HANDLE THE H5 FEATURES BEST THROUGH 24 HRS.
ETA/NGM/AVN ALL IN FAIRLY DECENT AGREEMENT WITH MOVEMENT OF STGR S/W
MOVING OUT OF NRN/CNTRL ROCKIES LT SUN.  ETA AND NGM LOOKED GOOD
WITH SFC MSLP PTTN BUT WERE SOME 3-4 MB TOO LOW ON PRESS VALUES.
THIS SEEMS TO BE OCCURING A LOT OF LATE AND ALSO MAY ACCOUNT FOR THE
CONSISTANTLY TOO WARM TMPS BEING FCST BY MOS GUIDANCE.

FEELING TONIGHT IS THAT WE'LL SEE SOME SCT SHRA/TSRA CONTG TO DEVLP
AND GET MORE ORGANIZED ALONG THE AFOREMENTIONED BAROCLINIC ZONE.
THIS FEATURE IS FCST TO MOVE NORTH INTO NRN KS BY MRNG.  EXPECT TO
SEE HEAVIEST PRECIP OVER THE ERN 1/3D TO 1/2 OF CWA.  WITH PW'S
CONTG FAIRLY HIGH WILL MENTION POSS HEAVY RAIN.  WITH A DAY OF
REPRIEVE FROM SIG RAIN AND THE FCST MOVEMENT OF BNDRY...WILL HOLD
OFF ON MENTION OF ANY WATCHES ATTM.

WILL CONT A MENTION OF SHOWERS INTO THE MRNG PD OVR NRN SCTNS OF
AREA.  H85 TMPS SHOW A WRMG TREND DURNG DAY SUNDAY AND WILL CONT
TREND OF WARMER TMPS THEN BUT WILL STILL BE GOING BELOW GUIDANCE.

SHOULD SEE ANOTHER CHC FOR TSRA SUN EVE/NGT AS NRN ROCKIES SWEEPS
EAST ACRSS HIGH PLAINS.

PRELIMINARY GUIDANCE FOR COORDINATION ONLY.  OFFICIAL FORECASTS ARE
CONTAINED WITHIN THE TOPZFPDDC.

.DDC...NONE.
