AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
231 PM CDT FRI JUN 30 2000

1ST PERIOD FCST CONCERNS...WHAT TO DO WITH POPS.

17Z SURFACE MAP DOESNT HAVE ANY REAL DEFINITE FEATURES...BUT LOOKS
LIKE A SURFACE TROF OVER S CENTRAL KS INTO CENTRAL OK.  A BAND OF
70 DEWPOINTS MOVING AHEAD OF TROF INTO ERN OK ATTM.  STLT/RADAR
SHOWS AREA OF SHOWERS ACROSS OUR NERN ZONES MOVING SE. OTHERWISE
NO OTHER AREAS OF CONVECTION TO OUR W/NW ATTM.

SRN 1/2 HALF OF CWA IS SEEING MORE SUN THAN NRN HALF. THUS THE
POSSIBILITY OF TSRA FORMING ALONG BOUNDARY IS SOMETHING TO WATCH OUT
FOR AS NOTED BY GROWING CU FIELD IN SRN ZONES.

THINKING ABOUT USING THIS EVENING AND LEAVE POPS OUT FOR THE
OVERNIGHT HOURS FOR 1ST PERIOD....BUT WILL NOT GET FANCY WITH THE
POPS WORDING AND JUST BROAD BRUSH THE WHOLE 1ST PERIOD WITH A POP.
NEXT PROBLEM IS WHETHER TO UP THE CURRENT POPS...ATTM THINKING ABOUT
RAISING THE POPS TO AROUND 40 OVER SW MO/SE KS...WITH HIGHER
AMOUNTS TO THE E/NE.

NGM DIDNT DO GOOD JOB WITH CURRENT PCPN...WILL GO WITH MESO-ETA/AVN.
ALSO BIG DIFFERENCE WITH FWC AND FAN VALUE...WITH FAN BEING THE
COOLER ONE. PROBABLY WILL SPLIT THE DIFFERENCE.

THE PROBLEMS ONLY CONTINUES...MESO-ETA PRINTING OUT PCPN ON
SATURDAY NIGHT LATE AND SUNDAY.  1000-500 RH ARE AROUND 40/50
PERCENT SATURDAY NIGHT...WILL PROBABLY LEAVE OUT POPS FOR NOW ON
SATURDAY NIGHT (SILENT 20 POP) AND MIGHT THROW IN A LOW POP ON
SUNDAY.

EXTENDED FCST...WILL LEAVE DRY AND WARM ATTM.
