AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TOPEKA KS
221 PM CDT FRI JUL 30 2010

.DISCUSSION...

...FOCUS IS ON CONVECTIVE CHCS THIS EVENING AND TEMPS NEXT 36 HRS.

WATER VAPOR IMAGERY SHOWS A SUBTLE SHORTWAVE TROUGH MOVING THROUGH
IA/NE AND INTO MO. 500-700MB PROFILER NETWORK SUGGESTS THAT THE
TROUGH AXIS MAY BE SHIFTING EAST OF THE CWA BY 21Z SHIFTING THE MORE
FOCUSED MESOSCALE LIFT TO OUR EAST BY PEAK HEATING. THAT
SAID...MODEST ISENTROPIC LIFT/WAA IN THE 850-600MB LAYER SHOULD
COMBINE WITH DAYTIME HEATING TO SET THE STAGE FOR SCT TSRA TO
DEVELOP ALONG THE SFC FRONT FOR THE NEXT SEVERAL HOURS. MODEST 6KM
SHEAR OF 20 TO 30KTS AT BEST ACROSS OUR NE COUNTIES ALONG WITH
EXTREME INSTABILITY COULD YIELD SOME STORMS WITH SEVERE WIND GUSTS
BUT POOR MID LVL LAPSE RATES AND AFOREMENTIONED WEAK SHEAR SHOULD
LIMIT THE COVERAGE OF ANY SVR THREAT. ANY STORMS SHOULD PRODUCE VERY
HIGH RAIN RATES WITH WARM CLOUD DEPTH AND PWATS. CURRENT FCST OF
30-50 POPS THROUGH 00Z LOOKS REASONABLE WITH SCT TSRA EXPECTED.

TONIGHT...LACK OF SUPPORT FOR MORE ORGANIZED CONVECTION SHOULD LEAD
TO A DIMINISHING TREND IN THE COVERAGE OF STORMS OVERNIGHT. THE
FRONT WILL ONLY MAKE SLOW PROGRESS SOUTH AND WITH DEWPOINTS POOLING
NEAR THE BOUNDARY WE FAVOR THE WARMER MOS GUIDANCE TONIGHT.

SAT...THE FRONT WILL CONTINUE TO DRIFT SOUTH THROUGH THE AREA DURING
THE MORNING WITH SOME SMALL CHCS FOR PRECIP ACROSS OUR SOUTHERN
COUNTIES THROUGH MIDDAY BEFORE THE FRONT MOVES SOUTH OF THE AREA.
MOS GUIDANCE IS IN GOOD AGREEMENT THAT WE WILL SEE SLIGHTLY COOLER
AIR TEMPS HOWEVER DEWPOINTS MAY REMAIN IN THE UPPER 60S TO LOWER 70S
SO IT WILL REMAIN HUMID WITH HEAT INDICES IN THE 95 TO 100 RANGE
MOST AREAS.

UPPER RIDGING IS EXPECTED TO BUILD FURTHER INTO THE PLAINS OVER
THE REST OF THE WEEEKEND INTO EARLY NEXT WEEK. THE REMNANT
BOUNDARY WILL LIFT NORTH THROUGH NORTHEAST KANSAS WITH SURFACE
LOW PRESSURE DEEPENING IN THE HIGH PLAINS. SOUTHERLY ADVECTION
WILL REINFORCE A MOIST AIRMASS ACROSS THE REGION. FORECAST MODELS
DEPICT AN UPPER TROUGH MOVING THROUGH THE UPPER MIDWEST WITH AN
ASSOCIATED WEAK COLD FRONT MOVING INTO THE NORTHERN AND CENTRAL
PLAINS. THIS FRONT IS PROGGED TO APPROACH NORTHERN KANSAS LATE
MONDAY NIGHT AND LINGER ACROSS NORTHEAST KANSAS INTO THE MIDDLE
OF NEXT WEEK. ISOLATED TO WIDELY SCATTERED THUNDERSTORMS WILL BE
POSSIBLE NEAR THIS BOUNDARY DURING THE LATE AFTERNOON AND EARLY
EVENING HOURS.
