AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WICHITA KS 305 AM CDT THU JUL 12 2007 .DISCUSSION... FORECAST CONCERNS... CONVECTIVE TRENDS AND AREAL EXTENT/PLACEMENT OF HEAVY RAINFALL TODAY AND TONIGHT... AT EARLY MORNING...CONVECTIVE CLUSTER/DEVELOPING MCS WAS ONGOING ACROSS WEST-CENTRAL/SOUTHWEST KANSAS. ALL SHORT RANGE MODELS WERE SUPPORTIVE OF THIS SCENARIO...THOUGH DIFFERED ON AREAL PLACEMENT AND TRACK. LATEST RUC MAY HAVE BEST HANDLE IN THE SHORT TERM...BASED ON RADAR/SATELLITE TRENDS...TAKING COMPLEX SOUTHEAST ACROSS SOUTH CENTRAL KANSAS THROUGH MID-MORNING. ALTHOUGH CONVECTION MAY WANE BY LATE MORNING...EXPECT SOME FESTERING ACROSS SOUTH CENTRAL AND PORTIONS OF SOUTHEAST KANSAS THROUGH MIDDAY. THIS WILL STUNT DIURNAL TEMPERATURE RISE...SO HAVE CUT MAXS DOWN A BIT THERE. BETTER CHANCES FOR MORE SUNSHINE AND STRONGER SURFACE HEATING TO BE REALIZED ACROSS PORTIONS OF CENTRAL AND SOUTHWEST KANSAS THIS AFTERNOON...AND EXPECT THIS TO BE THE AREA FOR CONVECTIVE REDEVELOPMENT. A VERY UNSTABLE AIRMASS AND MODEST DEEP LAYER SHEAR IN NORTHWEST FLOW ALOFT WILL SUPPORT ORGANIZED SEVERE CONVECTION...WHICH COULD AFFECT CENTRAL OR SOUTH CENTRAL KANSAS LATE IN THE AFTERNOON OR EARLY EVENING. HIGH PRECIPITABLE WATER VALUES AROUND 1.8 INCHES WILL MAKE FOR HEAVY RAIN PRODUCERS AS WELL. CURRENT FLASH FLOOD WATCH WILL BE MAINTAINED IN TIME...WITH BARTON COUNTY ADDED IN CENTRAL KANSAS. CONFIDENCE IS A BIT HIGHER FOR SOUTH CENTRAL KANSAS COUNTIES TODAY AND TONIGHT. THE LATEST SHORT RANGE MODELS ARE A BIT MORE BEARISH ON THE DRIER AIR ADVECTION ON FRIDAY AND SATURDAY...THOUGH FORECAST CONSENSUS STILL SUPPORTS DWINDLING OF PRECIP CHANCES FROM NORTH TO SOUTH ON FRIDAY...WITH DRY WEATHER ACROSS THE AREA ON SATURDAY. WILL LET DAY SHIFT GET ANOTHER GANDER AT NEXT MODEL RUN BEFORE MAKING ANY NEEDED TWEAKS TO WEEKEND FORECAST. NO CHANGE TO OUTER PERIODS WITH THIS FORECAST CYCLE. DARMOFAL && .AVIATION... FOR 06Z TAF ISSUANCE: ALTO CUMULUS CONTINUES INCREASE ACROSS THE AREA AT THIS TIME...AS LIFT ALONG THE 315K ISENTROPIC LAYER CONTINUES. THIS LIFT WILL EVENTUALLY LEAD TO SHRA/TSRA TO DEVELOP TO THE WEST OF KHUT/KRSL AFTER 09Z. THIS AREA OF CONVECTION WILL CONTINUE TO EXPAND AND MOVE NORTHEAST BETWEEN 09-12Z. SO HAVE INTRODUCED VCTS FOR KHUT/KRSL AND KSLN STARTING AFTER 09Z. ITS AFTER 12Z WHEN CEILINGS WILL BEGIN TO DETERIORATE AS WARM ADVECTION AND CONTINUED MOISTURE TRANSPORT AND ISENTROPIC LIFT WILL LEAD TO CONVECTION BREAKING OUT ALMOST ANYWHERE ACROSS THE REGION. SO WILL INCLUDE VCTS FOR MOST LOCATIONS FOR THE DAYTIME HOURS. WILL ALSO SEE MVFR CEILINGS ALSO BECOME MORE PROMINENT AS INCREASED TSRA IN THE AREA WITH LOW LEVEL MOISTURE INCREASING.
