AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 357 PM CDT WED JUN 23 2010 .DISCUSSION... THIS AFTERNOON THROUGH THURSDAY...CENTRAL CONUS PATTERN CHARACTERIZED BY A SHORTWAVE TROUGH MOVING ACROSS SOUTH DAKOTA IN MINNESOTA WITH A TRAILING COLD FRONT SLICING THROUGH KANSAS. AS OF EARLY THIS AFTERNOON...THIS BOUNDARY WAS LOCATED FROM NEWTON TO JUST NW OF TOPEKA. TO THE NORTH OF THIS LINE...TEMPERATURES WERE IN THE UPPER 70S TO MIDDLE 80S WITH MUCH DRIER AIR ADVECTING INTO THE AREA WITH DEWPOINTS IN THE MIDDLE 60S. SOUTH OF THIS LINE...AN UNSTABLE ATMOSPHERE EXISTS WITH TEMPERATURES IN THE 90S AND DEWPOINTS IN THE LOWER 70S. MLCAPE VALUES OF 2500 J/KG ARE COMMON OVER THE AREA WITH RAPIDLY ERODING CINH OVER NORTHEAST KS. STILL ANTICIPATE CONTINUED SFC CONVERGENCE ALONG THE BOUNDARY WILL ALLOW FOR SCT CONVECTIVE INITIATION FIRST ACROSS NORTHERN MISSOURI AND THEN BACKBUILD SWWARD OVER PORTIONS OF NORTHEAST INTO EAST CENTRAL KS BETWEEN 21-23Z. WITH AN UNSTABLE ATM...STORMS THAT ARE ABLE TO MATURE MAY BECOME SEVERE...ALTHOUGH OVERALL SVR POTENTIAL SHOULD BE LIMITED BY WEAK DEEP LAYER SHEAR WITHIN THE WARM SECTOR. THEREFORE BEST CHANCES FOR HAIL WILL BE WITH INITIAL DEVELOPMENT WHEN UPDRAFTS ARE MORE ISOLATED...AND WIND POTENTIAL WITH MICROBURSTS AND/OR UPSCALE GROWTH COLD POOL. COLD FRONT IS EXPECTED TO CLEAR THE TOP CWA BY 03Z...LIKEWISE ENDING PRECIP CHANCES AS COOLER/DRIER AIR MOVE IN. LOWS TONIGHT WILL FALL INTO THE 60S WITH MOSTLY CLEAR SKIES. SFC HIGH PRESSURE BRIEFLY TAKES CONTROL OF THE AREA ON THU...RESULTING IN MOSTLY CLEAR SKIES AND COOLER READINGS WITH HIGHS IN THE MIDDLE 80S. BLAIR RIDGE OF HIGH PRESSURE MOVES OFF TO THE EAST THURSDAY AS LOW PRESSURE DEVELOPS IN THE LEE OF THE ROCKIES. RESULTING LOW-LEVEL WARM ADVECTION HELPS AMPLIFY UPPER RIDGE ACROSS CENTRAL U.S. FOR FRIDAY INTO SATURDAY MORNING...ALSO KEEPING CONVECTIVE SYSTEMS WELL TO THE NORTH DURING THAT TIME. SHORTWAVE TROUGH AND SURFACE LOW MOVING THROUGH THE NORTHERN PLAINS ON SATURDAY...DRAGS A COLD FRONT INTO CENTRAL AND NORTHERN KS BY LATE SATURDAY NIGHT...WITH INCREASING CHANCES FOR THUNDERSTORMS. ECMWF AND GFS BOTH BRING THE FRONT THROUGH ERN KS LATE SATURDAY NIGHT AND SUNDAY...WITH THE GFS FASTER. IT IS POSSIBLE THE PRECIPITATION WILL LINGER BEHIND THE FRONT ACROSS EC KS SUNDAY EVENING...IF THE ECMWF IS CORRECT WITH THE SLOWER MOTION OF THE FRONT. AFTER THAT...UPPER RIDGE BUILDS TO THE WEST...WITH ERN KS IN NWLY FLOW ALOFT. SOME DISCREPANCY AMONG THE MODELS FOR TEMPERATURES TUESDAY AND WEDNESDAY OF NEXT WEEK AS 00Z AND 12Z ECMWF KEEP UPPER RIDGE FARTHER WEST AND NELY OR ELY LOW-LEVEL FLOW OVER ERN KS. THIS WOULD KEEP HUMIDITY LEVELS DOWN AND TEMPERATURES IN THE PLEASANT 80S FOR HIGHS. GFS ON THE OTHER HAND HAS A MORE EWD POSITION OF THE UPPER RIDGE...WHICH WOULD BRING THE WARMTH AND HUMIDITY BACK FASTER. HAVE GONE CLOSER TO THE ECMWF SOLUTION...WHICH HAS CONTINUITY...AND THUS THE COOLER HIGHS NEXT WEEK. GDP && .AVIATION... VFR CONDITIONS PREDOMINANT CATEGORY THROUGH THE FORECAST PERIOD.
