AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
300 PM CDT TUE JUL 11 2006

.DISCUSSION...
FORECAST CONCERNS WILL DEAL WITH CONVECTIVE EPISODES TONIGHT THROUGH
THURSDAY...FOLLOWED BY HOT TEMPS FOR THE WEEKEND INTO EARLY NEXT
WEEK.

TONIGHT
CURRENT WATER VAPOR IMAGERY/PROFILER NETWORK SHOWS A SHORT WAVE
MOVING INTO WESTERN KANSAS. THUNDERSTORMS HAVE BEEN RAPIDLY
DEVELOPING ALONG A FRONTAL BOUNDARY SITUATED FROM WESTERN KANSAS
TOWARDS CENTRAL KANSAS...AS MASS CONVERGENCE INCREASES ALONG THE
BOUNDARY. THUNDERSTORM ACTIVITY SHOULD CONTINUE INTO THE NIGHT TIME
HRS AS NUMEROUS STORM-SCALE OUTFLOW BOUNDARIES CAUSE ADDITIONAL
DEVELOPMENT. A FEW STRONG TO SEVERE STORMS WILL BE POSSIBLE GIVEN
FAVORABLE WET MICROBURST POTENTIAL FROM COLLAPSING CORES. LOCALLY
HEAVY RAINFALL WILL ALSO BE A RISK DUE TO TROPICAL AIRMASS IN PLACE
ALONG WITH SLOW STORM MOVEMENT. MEANWHILE...PATCHY AREAS OF FOG
COULD DEVELOP LATER TONIGHT ACROSS PORTIONS OF CENTRAL KANSAS BEHIND
THE FRONT WITH DECOUPLED BOUNDARY LAYER WINDS AND CLEARING SKIES.

WED-THUR
THUNDERSTORMS WILL BE POSSIBLE YET AGAIN FOR THIS PERIOD AS MODELS
SHOW ANOTHER IMPULSE SLIDING EAST ACROSS THE REGION FOR WEDNESDAY
INTO WEDNESDAY NIGHT. THUNDERSTORM CHANCES WILL DEPEND ON
POSITIONING OF THE LOW LEVEL BOUNDARY WHICH SEEMS LIKE IT COULD
STALL OUT OVER SOUTHERN KANSAS FOR WEDNESDAY. THE HEAT AND HUMIDITY
WILL INCREASE ON THURSDAY WITH TEMPS RISING INTO THE MID AND UPPER
90S.

FRI
WILL KEEP THE DRY AND HOT CONDITIONS GOING FOR THIS PERIOD...HOWEVER
MODELS ARE STILL PERSISTENT WITH A SHORT WAVE MOVING VERY SLOWLY
SOUTHWARD ACROSS EASTERN KANSAS. WILL LET LATER SHIFTS RE-EVALUATE
THIS POTENTIAL BEFORE EXTENDING POPS INTO FRIDAY.

EXTENDED: SAT-TUES
HOT AND HUMID CONDITIONS WILL AFFECT KANSAS DURING THIS
PERIOD...WITH HEAT INDICES ABOVE 100 AND DRY WEATHER CONDITIONS
PREVAILING.

A WEAK UPPER LEVEL DISTURBANCE COULD DROP SOUTHWARD ACROSS
MISSOURI/EASTERN KANSAS FOR THE WEEKEND WITH POSSIBLE ISOLATED
DIURNAL ACTIVITY...HOWEVER PRECIP CHANCES LOOK TOO REMOTE TO
INTRODUCE ANYTHING AT THIS JUNCTURE FOR SOUTHEAST KANSAS. A COLD
FRONT IS EXPECTED TO SLIDE SOUTHWARD ACROSS THE NORTHERN PLAINS FOR
EARLY NEXT WEEK...AND HOW FAR SOUTH WILL THE FRONT MAKE IT BEFORE IT
STALLS OUT IS THE MAIN CHALLENGE. PRESENT MODEL INDICATIONS SUGGEST
THAT THE FRONT COULD MAKE IT INTO KANSAS BY TUESDAY...BUT FEEL THAT
THE HEAT WILL STILL BE OVER THE AREA THROUGH TUESDAY. THE HEAT AND
HUMIDITY COULD VERY WELL CONTINUE THROUGH MUCH IF NOT ALL OF NEXT
WEEK...ESPECIALLY IF A MODEST TROUGH DIGS INTO THE NORTHWEST COAST
THUS AMPLIFYING THE DOWNSTREAM UPPER RIDGE ACROSS THE CENTRAL
PLAINS.
