AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 556 PM CDT WED JUL 2 2008 .UPDATE... UPDATED FOR 00 UTC AVIATION. && .DISCUSSION... SEE PREVIOUS DISCUSSION. && .AVIATION... SYNOPTIC FRONT STILL ANALYZED NORTH OF THE TERMINALS WITH CONVECTION DEVELOPING ALONG THE BOUNDARY OVER SOUTHERN IA AND SOUTHEASTERN NEB. COVERAGE STILL A LITTLE SPOTTY ALONG THE BOUNDARY WITH SATELLITE SHOWING SOME CU BETWEEN BIE AND FNB. CONVECTION AROUND EMP IS EXPECTED TO REMAIN SOUTH OF THE TERMINALS. WILL HAVE TO MONITOR CONVECTIVE TRENDS WITH RUC SOUNDINGS AND LAPS ANALYSIS SHOWING LITTLE CIN ALONG THE SYNOPTIC FRONT FOR TIMING OF POSSIBLE TS IN THE TERMINALS. THOUGH WOULD LIKE TO SEE MORE DEVELOPMENT WEST ALONG THE BOUNDARY BEFORE CONFIDENCE IN TS INCREASES. WILL LIKELY KEEP TEMPO TS SIMPLY TO KEEP CONSISTENCY WITH PREVIOUS FORECASTS. WOLTERS && .PREV DISCUSSION.../324 PM CDT/ NARROW BAND OF SHOWERS AND WEAK THUNDERSTORMS MOVING SOUTHEAST THRU NORTHEAST KANSAS CURRENTLY AND WEAKENING. THIS BAND OF MID LEVEL SHOWERS NOT VERY IMPRESSIVE WITH WARM CLOUD TOPS AND LITTLE IN THE WAY OF LIGHTNING. CLOUDS ALSO DECREASE BEHIND THIS BAND OF SHOWERS...SO MORE SUNSHINE IN THE NORTHERN PORTION OF OUR CWA SHOULD HELP ERODE THE CAP IN THIS AREA. 18Z SOUNDING FROM TOPEKA SHOWED A CAP REMAINING AND FORECAST SOUNDINGS ALSO SHOW CAP HOLDING OVER NORTHEAST KS THRU 22Z. MCV MOVING THRU EASTERN NEBRASKA HAS CAUSED SOME THUNDERSTORMS TO DEVELOP IN EASTERN NEBRASKA. SURFACE FRONT SEEMS TO BE MAKING SLOW PROGRESS SOUTHWARD...AS IT REMAINS IN SOUTHEAST NEBRASKA...TO NORTH CENTRAL KANSAS. AS THE CAP CONTINUES TO WEAKEN AND SURFACE FRONT MOVES FARTHER SOUTH THIS EVENING...EXPECT THUNDERSTORMS TO DEVELOP ACROSS THE CWA. MAIN CONCERN WILL BE LOCALIZED HEAVY RAINFALL. SOME OF THE STORMS COULD BECOME SEVERE WITH LARGE HAIL OR DAMAGING WINDS. KEPT HIGHEST POPS IN THE NORTHERN PORTION OF THE CWA EARLY THIS EVENING AND THEN SHIFTED FAVORED AREA FOR PRECIPITATION SOUTH AFTER MIDNIGHT. ON THURSDAY...THE FRONTAL BOUNDARY HANGS UP IN EAST CENTRAL KANSAS AND KEPT HIGHEST POPS IN THIS AREA. HOWEVER...IT IS DIFFICULT AT THIS TIME TO KNOW EXACTLY WHERE THE BOUNDARY WILL SET UP. LOWS TONIGHT IN THE LOWER 60S NORTH TO UPPER 60S SOUTH. HIGHS THURSDAY IN THE MID 70S NORTH TO LOWER 80S SOUTH. BASED THURSDAY NIGHT FCST MORE IN LINE WITH THE NAM SOLN AS THE GFS CONTINUES TO SUFFER FROM CONVECTIVE FEEDBACK WITH ITS PROJECTION OF AN MCS TOO FAR TO THE NORTH IN THE CWA. ALSO...PREFER THE MORE SOUTHERLY POSITION OF THE FRONT INTO OK THAN THE GFS SHOWS. AS A RESULT...CONTINUED TO KEEP THE HIGHER CHC POPS ACROSS THE EAST CENTRAL AND ONLY SLIGHT CHANCE ACROSS THE NORTHERN CWA. ALSO...TRIMMED SLIGHT CHC POPS FRIDAY TO AREAS MAINLY SOUTH OF THE I 70....THEN WENT DRY FRIDAY NIGHT INTO SATURDAY AS FLOW ALOFT WEAKENS FURTHER AND WARMING ALOFT SPREADS EASTWARD AS UPPER RIDGE IS PUSHED EASTWARD INTO THE PLAINS. ALSO...RAISED HIGH TEMPS SLIGHTLY INTO THE WEEKEND WITH THE UPPER RIDGE BUILDING EASTWARD INTO THE PLAINS AND MORE IN THE WAY OF SUNSHINE EXPECTED THAN PREVIOUS FCST. MODELS KEEPING UPPER RIDGE ACROSS THE PLAINS THROUGH THE WEEKEND WITH FCST PROFILES SHOWING A GOOD CAP IN PLACE. HAVE LEANED WITH THE ECMWF AND WENT WITH A DRY WEEKEND FOR NOW UNTIL SUNDAY NIGHT INTO MONDAY WHEN ANOTHER SHORTWAVE IS FCST TO MOVE EAST THROUGH THE NORTHERN PORTIONS OF THE RIDGE WITH A SLIGHT CHANCE FOR PRECIP GENERALLY NORTH OF I 35...BEFORE RIDGING ALOFT REAMPLIFIES THROUGH MID WEEK. HAVE THEREFORE KEPT TUESDAY AND WEDNESDAY DRY WITH HIGHS IN THE LOW TO MID 90S. && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. &&
