Area forecast discussion, Jul 1, 1:53 AM CDT, 9 hours 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
153 AM CDT THU JUL 01 1999

I WILL KEEP IT SHORT AND SWEET DUE TO THE WEATHER.

MAIN PROBELM WILL BE HOW LONG TO HOLD ONTO THE POPS TODAY AND HOW
HOT WILL IT GET LATER IN THE PERIOD.

03Z SURFACE CHART SHOWED LOW PRESSURE IN SOUTHEAST COLORADO WITH
NEARLY STATIONARY BOUNDARY STRETCHING FROM NEAR GCK...DDC...EMP...TO
MKC.  WITH A VERY MOIST ATMOSPHERE AND A WEAK FORCING MECHANISM PRESENT
...SHOWERS AND THUNDERSTORMS HAVE BEGUN TO FIRE.  I EXPECT THE
PRECIPITAITON TO DEVELOP MORE INTO AN MCS TYPE SCENARIO CLOSER TO
SUNRISE...SO POPS WILL BE KEPT THROUGH THE MORNING HOURS.  THE WEAK
BOUNDARY THEN DROPS SOUTH AND STRETCHES FROM NEAR ICT TO MKC BY
F18.  THIS WOULD PUT THE PRIME AREA OF PRECIPITATION IN SOUTHEAST
KANSAS...SO CHANCE POPS WILL BE KEPT THROUGH THE DAY AND INTO THE
EVENING.  I AM STILL ON THE FENCE HERE IN SC KANSAS FOR THE EVENING HOURS
...SO I WILL DECIDE BY ISSUANCE TIME.  IF I DO KEEP THE POPS...THEY
WILL BE SLIM.  CENTRAL SHOULD BE IN THE CLEAR THIS AFTERNOON AND
TONIGHT WITH DRYING NORTH FLOW.  THE BOUNDARY THEN SINKS INTO
OKLAHOMA BY F30 AND SOON WASHES OUT AND ALLOWS GOOD RETURN FLOW ON
FRIDAY. I WOULD THINK A BIG ENOUGH CAP WILL BE IN PLACE...SO I WILL
DROP THE SLIGHT CHANCE POPS AT THIS TIME

THE FWC VALUES LOOK REASONABLE WITH GOOD WARM AIR ADVECTION AT H8
THORUGH F48.

NUMBERS TO FOLLOW SHORTLY.

CHANCE

.ICT...NONE.
