NWS Topeka, KS wrote its last area forecast discussion before the first event at Jun 1, 11:19 PM CST, 2 hours 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 1219 AM CDT TUE JUN 2 2009 .UPDATE... UPDATED FOR 06Z AVIATION. && .DISCUSSION... SEE PREVIOUS DISCUSSION. && .AVIATION... ONGOING CONVECTION IS INITIAL CONCERN AS LOW LEVEL JET CONTINUES TO GENERATE THUNDER OVER OUTFLOW BOUNDARIES NEAR TAF SITES. WILL CARRY A TEMPO FOR THESE STORMS UNTIL THEY DIMINISH IN COVERAGE AND SHIFT NORTH AFTER 10Z. SECONDARY PUSH OF ENERGY WILL BRING FRONT BACK SOUTH DURING THE DAY TUESDAY AND HAVE BROUGHT BACK CIGS AND VCTS AFTER 18Z. ADDED NO ADDITIONAL GROUPS AS WINDS AND CIGS LIKELY TO BE SIMILAR THROUGH END OF THE TAF PERIOD AND CONVECTION TOO FAR OUT TO PEG ATTM. 67 && .PREV DISCUSSION... /ISSUED 402 PM CDT MON JUN 1 2009/ DISCUSSION... THE 18Z WATER VAPOR SATELLITE IMAGERY SHOWED A BROAD UPPER LEVEL RIDGE ACROSS THE WESTERN CONUS. A SERIES OF UPPER LEVEL TROUGHS WERE DIGGING EAST AND SOUTH EAST ACROSS SOUTHERN CANADA. A WEAK UPPER LEVEL LOW EMBEDDED WITHIN THE SOUTHERN BRANCH OF THE JET WAS MOVING EAST ACROSS NORTHWEST NM AND SOUTHWEST CO THIS AFTERNOON. A SURFACE COLD FRONT EXTENDED FROM SOUTHWEST IA...WEST AND SOUTHWEST TO NEBRASKA CITY...NE THEN WEST AND SOUTHWEST TO SOUTH OF HILL CITY...KS...THEN SOUTHWEST INTO A WEAK SFC LOW ACROSS THE OK PNHDL. SOUTH TO SOUTHWEST WINDS CONTINUE TO ADVECT LOWER TO MID 60 DEGREE DEWPOINTS NORTHWARD ACROSS EASTERN KS THIS AFTERNOON. THOUGH...AT 19Z MHK AND SLN HAVE MIXED OUT A BIT AS DEWPOINTS HAVE DROPPED INTO THE UPPER 50S. SFC CONVERGENCE AHEAD OF THE FRONT SHOULD PROVIDE ENOUGH LIFT FOR SCATTERED THUNDERSTORMS TO DEVELOP ACROSS SOUTHEAST NE...SOUTHWEST ACROSS WEST CENTRAL KS. THE THUNDERSTORMS THAT DEVELOP ALONG THE FRONT WILL BE PULSE STORMS DUE TO THE WEAK VERTICAL WINDSHEAR. THE THUNDERSTORMS ACROSS SOUTHEAST NE MAY PRODUCE OUTFLOW BOUNDARIES WHICH MAY MOVE SOUTHWARD INTO THE NORTHERN COUNTIES OF THE CWA EARLY THIS EVENING. THERE MAY BE ENOUGH SURFACE CONVERGENCE AHEAD OF THE OUTFLOW BOUNDARIES EARLY THIS EVENING FOR ISOLATED TO SCATTERED THUNDERSTORMS TO DEVELOP. SBCAPE VALUES OF 2000 TO 3000 J/KG MAY PROVIDE FOR POSSIBLE PULSE SEVERE THUNDERSTORMS ALONG AND NORTH OF HIGHWAY 36 EARLY THIS EVENING WITH QUARTER SIZE HAIL AND DAMAGING WIND GUSTS BEING THE PRIMARY HAZARD. I CAN NOT RULE OUT THE CAP BREAKING WITHIN THE WARM SECTOR ALLOWING FOR ISOLATED PULSE STORMS TO DEVELOP...BUT THE BETTER CHANCE SHOULD OCCUR ALONG THE FRONT NEAR THE NE BORDER LATE THIS AFTERNOON AND EVENING. THUNDERSTORMS DEVELOPING ACROSS EASTERN CO AND WESTERN KS LATE THIS AFTERNOON AND EVENING MAY CAUSE AN MCV TO DEVELOP. THE NAM MODEL SHOWS AN MCV DEVELOPING DUE TO THE HIGH PLAINS CONVECTION AND TRACKING EAST AND NORTHEAST ACROSS NORTH CENTRAL KS INTO SOUTHEAST NE LATER TONIGHT. THE LIFT AHEAD OF AN MCV COMBINED WITH ISENTROPIC LIFT NORTH OF THE BOUNDARY MAY CAUSE SHOWERS AND THUNDERSTORMS TO DEVELOP ACROSS THE NORTHERN COUNTIES OF THE CWA AFTER MIDNIGHT AND CONTINUE INTO THE MID MORNING HOURS OF TUESDAY. TUESDAY...A 5H TROUGH DIGGING SOUTHEAST ACROSS SOUTH CENTRAL CANADA INTO THE NORTHERN GREAT LAKES WILL HELP TO PUSH THE FRONT SOUTHWARD ACROSS THE CWA DURING THE AFTERNOON HOURS. THE WEAK UPPER LEVEL TROUGH OVER SOUTHWEST CO WILL ALSO MOVE EAST INTO WESTERN AND CENTRAL KS DURING THE AFTERNOON HOURS. SFC CONVERGENCE AHEAD OF THE FRONT AND ASCENT AHEAD OF THE WEAK UPPER LEVEL TROUGH WILL CAUSE SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS TO DEVELOP ALONG AND AHEAD OF THE SFC COLD FRONT. THE FRONT BY LATE AFTERNOON IS FORECASTED TO BE ALONG A HIAWATHA TO MHK TO CARLTON LINE. THE VERTICAL WINDSHEAR WILL CONTINUE TO BE WEAK WITH ONLY 15 TO 20 KTS OF 0-6KM BULK SHEAR. THOUGH SBCAPE WILL ONCE AGAIN BE 1500-2000 J/KG. THERE MAY BE SOME PULSE SEVERE THUNDERSTORMS WITHIN THE LINE OF THUNDERSTORMS THAT SHOULD DEVELOP ACROSS THE NORTHEAST AND CENTRAL COUNTIES OF THE CWA. THE SLOW MOVING STORMS MAY ALSO PRODUCE HEAVY RAINFALL AND LOCALIZED FLOODING. THE PRIMARY HAZARDS FROM ANY SEVERE THUNDERSTORM WILL BE QUARTER SIZE HAIL AND DAMAGING OUTFLOW WINDS. HIGHS ON TUESDAY WILL BE DEPENDENT ON CLOUD COVER AND THE TIMING OF THE FRONT. I KEPT THE NORTH CENTRAL COUNTIES COOLER IN THE LOWER TO MID 70S...SINCE FROPA MAY OCCUR DURING THE LATE MORNING HOURS. AREAS AHEAD OF THE FRONT DURING THE EARLY AND MID AFTERNOON HOURS SHOULD REACH AROUND 80 INTO THE LOWER 80S. IF WE SEE MORE ISOLATION IN THE WARM SECTOR THEN HIGH TEMPS MAY WARM INTO THE MID TO UPPER 80S. GARGAN TUESDAY AFTERNOON THROUGH THURSDAY...SQUALL LINE EXPECTED TO MOVE THROUGH THE AREA BY LATE TUESDAY NIGHT AND EARLY WEDNESDAY MORNING. ONCE THE LINE PASSES THROUGH THE AREA...DRY NORTHERLY WINDS WILL MOVE IN AND COOL THINGS OFF A BIT FOR WEDNESDAY AND EARLY THURSDAY. A BRIEF LULL IN THE ACTION IS EXPECTED FOR WEDNESDAY THROUGH FRIDAY. FLOW WILL RETURN TO SOUTHERLY AND WARM THINGS BACK UP FOR THE MIDDLE TO LATTER PART OF THE WEEK. THURSDAY AFTERNOON THROUGH MONDAY AFTERNOON...UNSETTLED WEATHER RETURNS TO THE PLAINS FOR THE WEEKEND. UPPER LEVEL TROUGH MOVING EASTWARD ACROSS CONTINENTAL CANADA WILL ALLOW A WEAK COLD FRONT TO MOVE THROUGH THE NORTHERN PLAINS AND INTO THE CWA TOWARD THE END OF THE WEEK. THE MAIN THREAT FOR RAIN WITH THIS FRONT WILL BE ACROSS THE FAR NORTHERLY COUNTIES. BEHIND THE DEPARTING FRONT A WEAKLY AMPLIFIED RIDGE SETS UP OVER SOUTHERN TEXAS...HOWEVER A CUTOFF LOW WHICH HAS BEEN STATIONARY OFF THE COAST OF CALIFORNIA WILL MOVE ON SHORE...AND DISPLACE THE RIDGE TO THE EAST. SURFACE LOW ASSOCIATED WITH THE INCOMING UPPER LEVEL WAVE WOULD BE THE FOCUS FOR RAIN DURING THE WEEKEND. BEST CHANCES FOR CONVECTION WOULD COME SUNDAY AFTERNOON AS THE COLD FRONT ASSOCIATED WITH THE DEPARTING SURFACE TROUGH MOVES THROUGH THE AREA. AS FOR NOW...HAVE ONLY INTRODUCED CHANCE POPS THROUGH THE WEEKEND AND WILL CONTINUE TO MONITOR THE PROGRESSION OF THE SYSTEM FOR ANY UPDATES TO POPS. WAA DUE TO SOUTHERLY FLOW AHEAD OF THE APPROACHING TROUGH COULD CAUSE TEMPERATURES TO RISE THROUGH NEXT WEEKEND...HOWEVER CLOUD COVER FROM THE PRE-WARM FRONTAL SHOWERS MAY MITIGATE STRONG SURFACE HEATING...THUS HAVE KEPT TEMPERATURES IN THE LOWER TO MID 80S FOR THE ENTIRE CWA THROUGH THE WEEKEND. JL && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. &&
