Area forecast discussion, May 31, 2:22 PM CST, 3 hours 38 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 322 PM CDT WED MAY 31 2006 .DISCUSSION... SCATTERED THUNDERSTORMS WERE DEVELOPING AS OF 18Z ACROSS THE NORTHEASTERN QUARTER OF THE CWA. STORMS WERE PUTTING DOWN SEVERAL OUTFLOW BOUNDARIES THAT MAY SERVE AS NEW INITIATION POINTS DURING THE AFTERNOON DUE TO THE MOISTURE/INSTABILITY IN PLACE...AND ARE FORMING ON THE WESTERN CIRCULATION OF A REMNANT MCV OVER WEST CENTRAL MISSOURI. CONVECTION SHOULD CONTINUE A SLOW BUT STEADY SOUTHWARD PUSH THIS EVENING AIDED BY ANY OUTFLOWS/ORGANIZED COLD POOLS THAT CAN BECOME ESTABLISHED. COVERAGE SHOULD GRADUALLY DIE DOWN AFTER SUNSET AS DAYTIME HEATING AND INSTABILITY DROP OFF. WITH THE RAINFALL TODAY AND LIGHT SURFACE WINDS TONIGHT...COULD SEE A REPEAT OF THE PATCHY FOG THAT WAS AROUND NORTHEAST KANSAS LAST NIGHT...BUT NOT EXPECTING ANYTHING TOO SERIOUS AS BOUNDARY LAYER FLOW IS A LITTLE STRONGER TONIGHT. THE BIG PICTURE FOR THURSDAY SHOWS THE MAIN TROUGH AXIS PASSING JUST NORTHEAST OF THE CWA AS UPPER RIDGE BUILDS OVER THE ROCKIES AND CREATES NW FLOW ALOFT OVER THE PLAINS. AT THE SURFACE...THE DEWPOINT GRADIENT FINALLY TRIES TO LIMP THROUGH DURING THE AFTERNOON...AND COULD SEE A FEW THUNDERSTORMS POP ALONG IT ACROSS THE SE QUARTER OF THE CWA DURING THE AFTERNOON AS THERE WILL BE SOME INSTABILITY AHEAD OF IT. STRASSBERG THURSDAY NIGHT...THE 5H TROUGH AXIS WILL MOVE SOUTHEAST INTO THE MID MS RIVER VALLEY. ANY THUNDERSTORMS THAT DEVELOP EARLIER IN THE AFTERNOON SHOULD MOVE SOUTHEAST INTO SOUTHEAST KS...SOUTHWEST MO THROUGH THE EVENING HOURS. I KEPT 15 POPS ACROSS THE SOUTHEAST COUNTIES IN CASE THE AFTERNOON THUNDERSTORMS ARE SLOW TO MOVE SOUTHEAST. SKIES SHOULD CLEAR AFTER SUNSET ACROSS THE CWA. A SURFACE RIDGE OF HIGH PRESSURE WILL BUILD SOUTHEAST ACROSS THE CWA...BRINING IN A SLIGHTLY COOLER AND DRIER AIRMASS. LOW TEMPERATURES WILL DROP INTO THE MID TO UPPER 50S. FRIDAY THROUGH MONDAY...A BROAD 5H RIDGE AXIS ALONG THE CONTINENTAL DIVIDE WILL SLOWLY MOVE EAST INTO THE WESTERN HIGH PLAINS. THE SURFACE RIDGE WILL MOVE EAST INTO MO AND WINDS WILL BECOME SOUTHERLY ACROSS THE CWA FRIDAY AFTERNOON INTO EARLY NEXT WEEK. DEEPER MOISTURE WILL BE ADVECTED NORTH ACROSS THE CWA...HOWEVER A STRONG CAP AND SYNOPTIC SCALE SUBSIDENCE UNDER THE 5H RIDGE SHOULD PREVENT STORMS FROM DEVELOPING...BUT ISOLATED THUNDERSTORMS MAY BE POSSIBLE ACROSS THE WESTERN COUNTIES DURING MAX AFTERNOON HEATING. I PLACED 10-14 POPS IN THE WESTERN COUNTIES SATURDAY...SUNDAY AND MONDAY AFTERNOONS. HIGH TEMPERATURES WILL WARM INTO THE UPPER 80S TO LOWER 90S. OVERNIGHT LOWS WILL BE IN THE 60S. MONDAY NIGHT THROUGH WEDNESDAY...THE EXTENDED RANGE MODELS ARE SHOWING A LONGER WAVE-LENGTH UPPER TROUGH DEVELOPING ACROSS THE GREAT LAKES STATES. THE UPPER 5H RIDGE WILL RETROGRADE WESTWARD ALLOWING FOR NORTHWEST FLOW ALOFT TO DEVELOP ACROSS EASTERN KS. THE GFS SHOWS A 5H TROUGH DIGGING SOUTHEAST ACROSS EASTERN KS AND WESTERN MO LATE MONDAY NIGHT AND TUESDAY. THERE MAY BE ENOUGH MOISTURE AND LIFT FOR THUNDERSTORMS...ESPECIALLY ALONG A COLD FRONT THAT MAY MOVE SOUTH ACROSS THE CWA ON TUESDAY. I PLACED SLIGHT POPS IN THE EXTENDED FORECAST FOR LATE MONDAY NIGHT AND TUESDAY. HIGH TEMPERATURES MAY COOL DOWN INTO THE LOWER TO MID 80S NEXT WEDNESDAY. && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. &&
