AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 319 PM CDT SUN JUL 10 2011 .DISCUSSION... FORECAST CONCERNS WILL BE CONTINUED HOT WEATHER INTO MON...AND ISOLATED DIURNAL STORM CHANCES EACH DAY INTO WED. THIS EVENING-TONIGHT: ANOTHER VERY HOT DAY IS UNDER WAY ACROSS MOST OF SOUTH CENTRAL KS...WITH TEMPS SOARING INTO THE LOWER 100S TO NEAR 110 AT KICT. ATMOSPHERE...REMAINS SOMEWHAT CAPPED...BUT WITH SFC TEMPS ACTUALLY APPROACHING CONVECTIVE TEMPS...SBCIN IS GETTING WEAKER AND WEAKER. LATEST WV SATELLITE SHOWS A WEAK PV-ANOMALY CURRENTLY ROTATING ACROSS CEN TX...WITH A LOBE OF THIS FEATURE ROTATING INTO SRN KS. BELIEVE THIS FEATURE WILL HELP WEAKEN THE CAP ENOUGH FOR AN ISOLATED STORM CHANCE ACROSS MOST OF SRN KS LATE THIS AFTERNOON INTO THIS EVENING...SIMILAR TO LAST EVENING. CURRENT RADAR IMAGES SHOWING ISOLATED SHOWERS TRYING TO GET GOING OVER SERN KS...AND EXPECT THIS TREND TO CONTINUE. SO WILL INCLUDE AN ISOLATED WORDING IN MOST AREAS...WITH A SLIGHT POP WORDING IN CEN KS...WHERE COOLER TEMPS AND A WEAK BOUNDARY IN THE AREA MAY LEAD TO WIDELY SCATTERED SHOWERS IN THIS AREA AS WELL. DO NOT THINK ANY CONVECTION...THAT CAN GET GOING ACROSS SRN KS...WILL LAST MUCH PAST SUNSET. BUT WILL KEEP A LOW POP IN CEN KS...AS MID LEVEL BAROCLINIC ZONE TIGHTENS AGAIN TONIGHT...WITH SOME ELEVATED SHOWERS/STORMS FESTERING IN CEN KS INTO THE OVERNIGHT HOURS. MON: MODELS FAIRLY SIMILAR ON THE UPPER LOW OVER CEN TX GRADUALLY SHIFTING A LITTLE FURTHER NORTHWARD TOWARDS SRN KS ON MON. A LITTLE CONCERNED ABOUT ANOTHER HOT DAY ON MONDAY...EVEN WITH A SLIGHT COOLING FROM THE UPPER LEVEL SYSTEM...BUT ALSO THINK THIS WILL KEEP SFC DEWPOINTS UP AS WELL...SO HEAT INDICES WILL STILL REACH HEAT ADVISORY CRITERIA AGAIN...SO EXCESSIVE HEAT WARNING...LOOKS FINE...GIVEN THE PROLONGED HOT SPELL. THINK MID LEVEL IMPULSE WILL AGAIN SPARK SOME DIURNAL STORMS ACROSS SRN KS AGAIN LATE MON AFTN/EVE. THINK STORMS WILL AGAIN BE ISOLATED AT BEST...SO WILL ADD THIS WORDING TO THE GRIDS/ZONES FOR MON. TUE-WED: TROPICAL WAVE/UPPER LOW WILL CONTINUE TO DRIFT NORTHEAST INTO SRN KS EARLY ON TUE...WITH MID LEVEL COOLING ASSOCIATED WITH THIS WAVE...KEEPING TEMPS DOWN SLIGHTLY ON TUE. BUT AS THIS COOLING MOVES OVER SRN KS...WEAK LIFT AND ADDED MID LEVEL MOISTURE WILL LEAD TO A DIURNAL STORM CHANCE ACROSS MOST OF SRN KS. NOT EXPECTING WIDESPREAD COVERAGE AS THE CONVECTION WILL BE MORE HIT OR MISS. STILL WORTH A CHANCE POP ALMOST ANYWHERE AS THIS WEAK WAVE MOVES ACROSS THE AREA ON TUE. NOT SURE HOW WED WILL PLAY OUT...AS TIMING OF THIS UPPER LOW MOVING ACROSS THE SRN KS MAY BE PROBLEMATIC. THINK THE ECMWF IS THE BEST COMPROMISE ON THE SPEED OF THIS FEATURE...WHICH WOULD STILL LEAD TO SOME STORMS LINGERING ACROSS THE ERN HALF OF KS INTO EARLY WED AS WELL. THU-SUN: AFTER THE UPPER WAVE DRIFTS EAST OF THE AREA WED EVE...THE UPPER RIDGE WILL BUILD IN WITH A VENGEANCE FOR THE END OF THE WEEK. THIS WILL BRING THE VERY HOT TEMPS BACK INTO THE PICTURE FOR THE END OF THE WEEK...WITH POSSIBLE MORE HEAT HEADLINES POSSIBLE...AS MAX TEMPS AGAIN WILL CLIMB ABOVE THE CENTURY MARK. CANNOT COMPLETELY RULE OUT A SOME ISOLATED STORMS FOR THIS PERIOD AS WELL...BUT THINK CHANCES ARE BELOW 14 PERCENT SO WILL KEEP THIS OUT OF THE FORECAST FOR NOW. KETCHAM .AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU VERY HOT TEMPERATURES COUPLED WITH A WEAK FRONTAL BOUNDARY COULD RESULT IN A FEW ISOLATED THUNDERSTORMS LATE THIS AFTERNOON THROUGH OVERNIGHT FOR MAINLY KSLN-KRSL. IN FACT...CANNOT RULE OUT A STRAY AFTERNOON/EVENING THUNDERSTORMS OVER THE REST OF SOUTH-CENTRAL AND SOUTHEAST KS DUE TO A VERY HOT AIRMASS IN CONCERT WITH WITH UPPER TROUGHING APPROACHING FROM THE SOUTHEAST. HOWEVER...THINKING THREAT IS SLIGHTLY HIGHER OVER CENTRAL KS...SO INSERTED "CB" WORDING AT KRSL-KSLN. ADK && .PRELIMINARY POINT TEMPS/POPS...
