Area forecast discussion, Aug 18, 2:05 PM CST, 3 hours 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 305 PM CDT THU AUG 18 2011 .DISCUSSION... MAIN FORECAST UPDATES WILL FOCUS ON THUNDERSTORM CHANCES FOR THE NEXT COUPLE DAYS ALONG WITH EXCESSIVE HEAT ON FRIDAY AFTERNOON. TONIGHT CURRENT CONDITIONS SHOW THUNDERSTORMS ERUPTING OVER NORTHEAST NEBRASKA WITH A STRONG INSTABILITY AXIS EXTENDING FROM EASTERN NEBRASKA SOUTHWARD INTO SOUTHEAST KANSAS. THE THUNDERSTORMS WILL BECOME MORE NUMEROUS AND EVOLVE INTO A MCS AND RACE SOUTH/SOUTHEAST TONIGHT ALONG THE INSTABILITY AXIS AND COULD CLIP SOUTHEAST KANSAS TONIGHT. SEVERE WEATHER IS LIKELY WITH THIS COMPLEX OF STORMS. MEANWHILE A FEW HIGH-BASED STORMS COULD POP OVER NORTH CENTRAL OKLAHOMA AND SOUTH CENTRAL KANSAS FOR LATE THIS AFTERNOON/EVENING WHERE SOME WEAK LOW LEVEL CONVERGENCE IS OCCURRING. PATCHY FOG COULD FORM OVER CENTRAL KANSAS TOWARDS DAYBREAK...AS LIGHT MOIST EASTERLY FLOW COMMENCES. FRI-SUN THE DANGEROUS HEAT INDICES WILL AFFECT MUCH OF THE REGION AGAIN FOR FRIDAY AFTERNOON...AND WILL KEEP THE HEAT ADVISORY IN PLACE. MEANWHILE LOCATION OF THE OUTFLOW BOUNDARY FROM THURSDAY NIGHT MCS WILL PLAY A ROLE IN FAVORED AREAS FOR THUNDERSTORM REDEVELOPMENT BY LATE FRIDAY AFTERNOON. EXPECTING DECENT MOIST UPSLOPE FLOW TO SPARK OFF THE NEXT ROUND OF STORMS IN THE HIGH PLAINS REGION FRIDAY AFTERNOON...WITH ANOTHER AREA OF STORMS POSSIBLE ALONG THE OUTFLOW BOUNDARY. THE ACTIVITY COMING OFF THE HIGH PLAINS WILL CONGEAL AND FORM ANOTHER MCS WHICH LOOKS TO IMPACT CENTRAL KANSAS FRIDAY NIGHT. SEVERE WEATHER WILL ONCE AGAIN BE A POSSIBILITY GIVEN EXPECTED SHEAR/INSTABILITY COMBINATION. THIS FRIDAY NIGHT ACTIVITY WILL MURKY THE FORECAST WATERS FOR SATURDAY WITH UNCERTAINTY ON LOCATION OF MESO-SCALE BOUNDARIES...THEREFORE WE WILL GO WITH SMALL CHANCE POPS FOR SATURDAY. WE WILL KEEP SUNDAY DRY AT THIS JUNCTURE FOR KANSAS WITH THE BOUNDARY LIKELY REMAINING SOUTH OF THE AREA. EXTENDED: MON-THU MODELS IN GOOD AGREEMENT THAT THE UPPER RIDGE WILL AMPLIFY OVER THE ROCKIES...WITH NORTHWEST FLOW ALOFT PERSISTING ACROSS THE CENTRAL PLAINS THIS PERIOD. A COUPLE UPPER WAVES WILL TRAVEL DOWN THE NORTHWEST FLOW REGIME WITH THE MOST ROBUST WAVE PREDICTED BY THE MODELS MOVING FROM THE NORTHERN PLAINS INTO THE GREAT LAKES DURING THE TUESDAY/TUESDAY NIGHT TIME FRAME. SHOWERS AND THUNDERSTORMS ARE LIKELY AHEAD OF THESE WAVES...BUT THE HIGHER CHANCES OF PRECIPITATION LOOK TO BE EAST OF KANSAS WHERE MOISTURE TRANSPORT IS FOCUSED. NEAR NORMAL TEMPERATURES AND DRY WEATHER SHOULD PREVAIL FOR WED/THU AS SURFACE HIGH PRESSURE BUILDS SOUTHWARD INTO THE CENTRAL PLAINS. JAKUB .AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU TWO TAF CONCERNS...FIRST WILL BE A CHANCE OF ISOLD/WIDELY SCT TSRA FROM EAST OF KSLN TO KCNU EARLY THIS EVENING IN CLOSE PROXIMITY TO A WARM FRONT LOCATED BASICALLY FROM KMHK TO KCNU. WILL PLACE A VCTS IN THE KSLN/KCNU TAFS FOR THIS INITIAL CHANCE. NEXT CONCERN WILL BE A CHANCE OF MORE NUMEROUS STORMS OVER SE NEB AND NE KS FORMING INTO A COMPLEX OF TSRA AND SURGING SOUTH TOWARDS SE KS VERY LATE THIS EVENING BETWEEN 03-07Z/FRI. THIS SURGING COMPLEX WILL AFFECT THE KCNU TAF SO WILL GO WITH A WIND SHIFT TO THE NORTH AND VCTS FOR THIS CHANCE. NOT COMPLETELY CONFIDENT TO ADD A TEMPO TSRA GROUP FOR GUSTY WINDS JUST YET...BUT COULD SEE A CHANCE OF VARIABLE GUSTY WINDS OF 25 TO 45 KTS WHEN IT ARRIVES. WILL ALSO TRY AND TIME A POSSIBLE OUTFLOW BOUNDARY FROM THIS COMPLEX INTO KICT/KSLN/KHUT BY AROUND 06Z WITH A WIND SHIFT TO THE EAST. KETCHAM && .PRELIMINARY POINT TEMPS/POPS...
