NWS Topeka, KS wrote its last area forecast discussion before the first event at Jun 27, 2:23 PM CST, 3 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 323 PM CDT WED JUN 27 2007 .DISCUSSION... COMPLEX WEATHER PATTERN OVER THE AREA TODAY. FRONTAL BOUNDARY FROM THE NORTH LINGERING SOMEWHERE ACROSS NORTH CENTRAL INTO NORTHEAST KANSAS...WHILE UPPER LOW OVER OKLAHOMA MOVES SLOWLY NORTHWARD. HAVE HAD AN INITIAL ROUND OF CONVECTION WITH THE NORTHERN FRONT PROMPTING HEAVY RAIN ALONG THE KS NE BORDER...AND ARE NOW SEEING A LINE OF HEAVIER RAINFALL ASSOCIATED WITH SOUTHERN LOW MOVING NORTH INTO EAST CENTRAL KS ATTM. DIFFICULT TO REFINE DETAILS WITH ONGOING CONVECTION...HOWEVER DO THINK THAT BOUNDARY CURRENTLY BISECTING THE CWA WILL CONTINUE TO MOVE SOUTHWARD SLOWLY THROUGH THE EVENING HOURS. AS UPPER LOW CONTINUES TO PROGRESS NORTH...EXPECT ONE TO ENHANCE THE OTHER AND BRING ADDITIONAL AREAS OF HEAVY RAIN TO EAST CENTRAL KANSAS. STORMS ARE RATHER PROLIFIC RAIN PRODUCERS...DROPPING AN INCH IN HALF AN HOUR IN SOME LOCATIONS. SHOWERS AND STORMS HAVE DIMINISHED IN INTENSITY AS BOUNDARY PASSES...SO THINK OUR NORTHERN COUNTIES WILL BE OK OUT OF THE WATCH ALTHOUGH LOCALLY HEAVY RAINFALL STILL POSSIBLE. SOUTHERN COUNTIES MAY GET A PROLONGED ROUND OF PRECIPITATION AND THINK THE WATCH IS STILL WARRANTED SO WILL STAY IN PLACE. HAVE KEPT HIGH POPS ALONG AND SOUTH OF I70 FOR THIS AFTERNOON INTO TONIGHT...AND DECREASED ALONG THE NORTHERN BORDER TO NO POPS AFTER MIDNIGHT AS SYSTEM SLOWLY GETS SHUNTED SOUTHWARD BY THE MEAN FLOW. WILL CARRY LIKELY POPS ALONG/SOUTH OF I35 IN THE MORNING THEN DIMINISH LATER IN THE DAY AS THREAT DECREASES. HAVE COOLED TEMPS A BIT AND INCREASED CLOUD COVER AND ADJUSTED QPF TO TRY AND BETTER CAPTURE ONGOING AND FORECAST PRECIP. 67 THURSDAY NIGHT...WITH THE SLOW MOVEMENT OF THE FRONTAL BOUNDARY TODAY AND THE MODELS HAVING DIFFICULTY JUST IN INITIALIZATION LEFT SOME LOW CHANCE TO SLIGHT CHANCE POPS ACROSS EAST CENTRAL KS OVERNIGHT. UPPER LEVEL RIDGING WILL BEGIN TO BUILD INTO NORTH CENTRAL KS OVERNIGHT SO WOULD NOT ANTICIPATE MUCH IN THE WAY OF PRECIPITATION FURTHER NORTH THAN I35. AS UPPER LEVEL RIDGING CONTINUES TO NUDGE EAST FRONTAL BOUNDARY SHOULD SINK SOUTH OF THE FORECAST AREA BY THE MORNING HOURS SO REMOVED POPS AFTER 12Z FRIDAY. FRIDAY THROUGH WEDNESDAY...IN GENERAL PATTERN WILL BE CHARACTERIZED WITH UPPER LEVEL RIDGING AND GRADUAL WARMING. INITIALLY IN THE PERIOD BEHIND THE PASSAGE OF THE WEAK COLD FRONT H500 RIDGE WILL BUILD IN WEST TO EAST ACROSS THE CWA CLEARING OUT ANY LINGERING PRECIPITATION ACROSS EAST CENTRAL KS BY FRIDAY AFTERNOON. BAND OF WESTERLIES WILL SET UP NORTH OF THE H500 RIDGE AXIS BRINGING LEE SIDE TROUGHING OVER THE WESTERN HIGH PLAINS BY SATURDAY. LEE TROUGHING WILL VEER LOW LEVEL WINDS AROUND TO THE SOUTH ACROSS THE ENTIRE FORECAST AREA BY SUNDAY AFTERNOON. BETWEEN SOUTHERLY FLOW AND MOSTLY SUNNY SKIES ASSOCIATED WITH MID TO UPPER LEVEL RIDGING TEMPERATURES WILL SLOWLY INCREASE THROUGHOUT THE PERIOD. HIGHS ON FRIDAY ARE EXPECTED TO TOP OUT IN THE LOWER TO MID 80S. HIGH TEMPERATURES WILL THROUGHOUT THE WEEK AND BY MONDAY HIGHS ARE EXPECTED TO CLIMB INTO THE LOWER TO MID 90S ACROSS THE FORECAST AREA. BY TUESDAY NIGHT AND INTO WEDNESDAY THE GFS WAS INDICATING AN AMPLIFICATION OF THE H500 RIDGE WEST OVER THE ROCKIES AS A FEW STRONG SHORTWAVES MOVE SOUTH OUT OF CANADA INTO THE GREAT LAKES REGION. IF THIS VERIFIES THE FLOW ALOFT WOULD TRANSITION TO NORTHWEST FLOW WITH AN AMPLIFIED RIDGE OVER THE WESTERN CONUS...AND A MEAN TROUGH OVER THE EAST COAST. WITH PERSISTENT SOUTHERLY FLOW AND TRANSITIONING NORTHWEST FLOW ALOFT TUESDAY NIGHT INTO WEDNESDAY THERE IS AN INCREASING CHANCE OF A POSSIBLE WEAK FRONTAL PASSAGE OR EMBEDDED SHORTWAVE PASSAGE THAT COULD SET OFF SOME CONVECTION ACROSS THE CWA. WITHOUT MUCH CONFIDENCE IN THESE RELATIVELY SMALL SCALE FEATURES OUT AT DAY 7 OF THE FORECAST PACKAGE HAVE LEFT THE FORECAST DRY AT THIS TIME. THE MIDDLE OF NEXT WEEK WILL HAVE TO BE MONITORED FOR PRECIPITATION CHANCES IF THE FLOW ALOFT DOES TRANSITION TO A NORTHWEST FLOW. CAVANAUGH && .AVIATION... HAVE CARRIED VFR CONDITIONS INITIALLY AT TAF SITES HOWEVER HAVE IFR CONDITIONS AT TIME OF GREATEST THREAT FOR HEAVY RAINFALL AND TSTORMS. HAVE DEPICTED HEAVIEST ROUNDS AT MHK IN THE AFTERNOON...WITH TOP AND FOE IN THE EVENING HOURS. AS FRONT MOVES SOUTH THINK THAT WILL BRING CIGS BACK UP TO MVFR IN THE EARLY MORNING HOURS. 67 && .TOP WATCHES/WARNINGS/ADVISORIES...FLASH FLOOD WATCH THROUGH 7 PM THURSDAY FOR KSZ040-054>056-058-059. &&
