Hail in Kansas, August 7, 2007

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
305 PM CDT TUE AUG 7 2007

.DISCUSSION...
THE MAIN FORECAST CONCERNS WILL BE WITH HIGH LEVELS OF HEAT AND
HUMIDITY FOR THE NEXT SEVERAL DAYS...FOLLOWED BY CONVECTION
CHANCES FOR TONIGHT AND TOMORROW.

TONIGHT
DECENT CAPPING IS KEEPING A LID ON CONVECTION OVER CENTRAL AND
NORTHERN KANSAS AT THIS JUNCTURE...HOWEVER STORMS COULD DEVELOP
LATER ON AS MOISTURE CONVERGENCE INCREASES ALONG THE FRONTAL
BOUNDARY. A FEW STRONG STORMS WITH GUSTY WINDS WILL BE POSSIBLE
GIVEN HIGH DCAPE VALUES FOR ANY COLLAPSING CORE.
OTHERWISE...ISENTROPIC ACCENT IN THE 310-315K LAYER/MOISTURE
TRANSPORT INCREASES LATER TONIGHT WHICH SHOULD INCREASE THE
THUNDERSTORM COVERAGE. THE BULK OF THE ACTIVITY LOOKS LIKE IT WILL
AFFECT LOCATIONS TO OUR NORTHEAST. VERY HIGH ATMOSPHERIC MOISTURE
SUGGESTS THAT HEAVY RAINFALL WILL BE A  POSSIBILITY WITH ANY OF THIS
ACTIVITY. WE COULD SEE A FEW STORMS DEVELOP TOWARDS MORNING FOR
LOCATIONS NEAR THE KANSAS TURNPIKE...AS THE LOW LEVEL JET VEERS OUT
A BIT AND ISENTROPIC ACCENT OCCURS ALONG THE 310-315K LAYER GRADIENT.

WED-FRI
WE WILL KEEP THE HEAT ADVISORY GOING FOR THE ENTIRE AREA THROUGH
WEDNESDAY. CENTRAL KANSAS COULD FALL A LITTLE SHORT OF ADVISORY
CRITERIA TOMORROW WITH CLOUD DEBRIS AND FRONTAL BOUNDARY PUSHING
INTO THE AREA...OTHERWISE SOUTHERN KANSAS SHOULD MEET HEAT ADVISORY
CONDITIONS ONCE AGAIN. WE COULD END UP ISSUING A HEAT WARNING IF
AFTERNOON HEAT INDICES OF 105 AND HIGHER PERSIST...STAY TUNED.
MEANWHILE...WATER VAPOR SATELLITE IMAGERY/PROFILER NETWORK SHOWS A
IMPULSE CURRENTLY POSITIONED OVER NEW MEXICO MOVING SLOWLY
NORTHWARD. THIS SHORT WAVE WILL MOVE CLOSER TO THE AREA FOR
WEDNESDAY WITH THUNDERSTORMS POSSIBLE ALONG THE FRONTAL BOUNDARY. WE
WILL KEEP THURSDAY DRY AND HOT BUT CANNOT RULE OUT SOME ACTIVITY
FROM BUBBLING UP OVER SOUTH CENTRAL KANSAS LATE THURSDAY AFTERNOON
IN THE MOIST AXIS...AS WEAK CONVERGENCE AND DAYTIME HEATING COULD
SPARK OFF A FEW STORMS. THE HOT AND DRY WEATHER WILL PERSISTENT INTO
FRIDAY AND HEAT HEADLINES COULD BE NEEDED FOR ALL OF THESE PERIODS.

EXTENDED: SAT-TUE
UPPER RIDGE CENTER WILL CONTINUE TO DOMINATE OVER THE CENTRAL PLAINS
THIS PERIOD THUS PROLONGING THE HOT AND DRY WEATHER
CONDITIONS...THEREFORE NO BIG CHANGES WERE MADE. SOME RELIEF FROM
THE HEAT COULD FINALLY ARRIVE BY MIDDLE OF NEXT WEEK IF MODELS
CONTINUE TO ADVERTISE UPPER LEVEL PATTERN TRANSITIONING TO A
NORTHWEST FLOW REGIME...THUS ALLOWING A FRONTAL BOUNDARY TO PUSH
SOUTHWARD ACROSS KANSAS.

JAKUB

.AVIATION...
THUNDERSTORMS WILL BEGIN TO DEVELOP ALONG THE FRONTAL BOUNDARY IN
NORTHERN AND CENTRAL KANSAS LATER THIS AFTERNOON. VFR CONDITIONS
ARE EXPECTED...HOWEVER POSSIBLE MVFR CONDITIONS COULD OCCUR DUE TO
PROXIMITY OF THUNDERSTORMS IN THE VICINITY OF RSL AND SLN TAF
SITES. THUNDERSTORMS ARE EXPECTED TO LINGER NEAR THE FRONTAL
BOUNDARY ALL NIGHT LONG WITH THE BULK OF THE ACTIVITY AFFECTING
LOCATIONS MAINLY NORTH OF CENTRAL KANSAS.
