NWS Topeka, KS wrote its last area forecast discussion before the first event at Jul 7, 5:13 PM CST, 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 613 PM CDT WED JUL 7 2010 .UPDATE... UPDATED THE AVIATION DISCUSSION. && .DISCUSSION... SEE PREV DISCUSSION. && .AVIATION... ATMOSPHERE REMAINS CONDITIONALLY UNSTABLE WITH A VERY MOIST AIRMASS IN PLACE. UNFORTUNATELY THERE IS NO ONE FEATURE FORCING CONVECTION. EVEN STORMS ALONG THE FRONT LOOK UNORGANIZED...DUE PRIMARILY TO WEAK SHEAR WITHIN THE ENVIRONMENT. THEREFORE IT IS DIFFICULT TO NAIL DOWN SPECIFICS IN TERMS OF SHRA IN THE TERMINALS. WILL KEEP A VC GROUP INTO THE EVENING. THEN KEPT TAFS OPTIMISTIC WITH MAINLY VFR CONDITIONS THROUGH TOMORROW. THINK THERE COULD BE SOME MVFR CIGS DEVELOP TOWARDS DAWN AS THE BOUNDARY LAYER COOLS. OTHERWISE CONFIDENCE IN ANY RESTRICTIONS TO CIGS AND VSBY ARE TO LOW TO MENTION. WOLTERS && .PREV DISCUSSION.../312 PM CDT WED JUL 7 2010/ SCATTERED SHOWERS CONTINUED TO DEVELOP ACROSS THE CWA. A CLUSTER OF THUNDERSTORMS WAS DEVELOPING ACROSS SOUTH CENTRAL KS...AND MAY MOVE NORTHEAST ALONG AND SOUTH OF THE KS TURNPIKE LATER THIS AFTERNOON AND THROUGH THE EVENING HOURS. A SFC COLD FRONT EXTENDED FROM EASTERN NE...SOUTH-SOUTHWEST TO MHK...THEN SOUTHWARD TO EAST OF ICT. THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS WILL BE ALONG AND AHEAD OF THE SFC COLD FRONT. THE NAM AND GFS BOTH SHOW THE FRONT MOVING SOUTHEAST OUT OF THE CWA BY 4 TO 5Z...THUS OUR CHANCE FOR HEAVY RAINFALL ACROSS EAST CENTRAL KS SHOULD COME TO AN END LATER TONIGHT. PW'S ACROSS EAST CENTRAL KS WILL BE AROUND 2.0 INCHES...THUS THE POTENTIAL FOR HEAVY RAINFALL WILL EXIST THIS EVENING FOR EAST CENTRAL KS. ANY FLOODING THIS EVENING WILL BE DEPENDENT ON WHERE AND WHEN BANDS OF THUNDERSTORMS WILL SET UP ACROSS EAST CENTRAL KS. SINCE THE HEAVY RAINFALL WILL BE MORE OF A MESOSCALE FORECAST A SHORT FUSE FLASH FLOOD WATCH FOR THIS EVENING WILL NOT BE ISSUED. HOWEVER...THERE IS THE POTENTIAL FOR SOME LOCALIZED FLOODING...GENERALLY ALONG AND SOUTH OF I-35 THROUGH THE EVENING HOURS. WEAK ISENTROPIC LIFT NORTH OF THE BOUNDARY MAY PROVIDE A CHANCE OF SHOWERS THROUGH THE REMAINDER OF THE NIGHT AND PERHAPS INTO THURSDAY ACROSS THE SOUTHERN COUNTIES OF THE CWA...BUT THE HEAVIER RAINFALL ASSOCIATED WITH THUNDERSTORMS ALONG THE FRONT SHOULD PUSH SOUTHEAST OF THE CWA LATER TONIGHT. THE GFS DOES SHOW BETTER ISENTROPIC LIFT NORTH OF THE BOUNDARY ALONG AND SOUTH OF I-35...THUS THERE COULD BE AN ADDITIONAL .25 TO .5 INCHES OF RAINFALL THROUGH THE DAY THURSDAY. THE NAM SHOWS AROUND A TENTH OF AN INCH OF QPF ACROSS ANDERSON COUNTY ON THURSDAY. TONIGHT LOWS WILL ONLY DROP INTO THE MID TO UPPER 60S. HIGHS ON THURSDAY WILL BE DEPENDENT ON CLOUD COVER AND RAIN CHANCES. ATTM...I WENT WITH LOWER TO MID 80S ACROSS THE CWA. IF WE SEE MORE INSOLATION THEN HIGHS MAY BE A FEW DEGREES WARMER. GARGAN PARTS OF EAST CENTRAL KANSAS MAY CATCH THE NORTHERN FRINGE OF THUNDERSTORM ACTIVITY EARLY THURSDAY NIGHT...BUT OTHERWISE EXPECT SURFACE HIGH PRESSURE TO BUILD ACROSS THE CWA BY FRIDAY AS THE SURFACE FRONT SAGS FURTHER SOUTH. TEMPERATURES WILL BE NEAR OR JUST BELOW NORMAL FOR FRIDAY AND SATURDAY WITH A SLIGHT WARMUP INTO THE LOWER 90S POSSIBLE BY SUNDAY. BY LATE IN THE WEEKEND...THE UPPER LEVEL FLOW PATTERN WILL TREND SLIGHTLY TOWARD ZONAL FLOW WITH A LONG WAVE TROUGH SITUATED INVOF THE HUDSON BAY. A SHORT WAVE TROUGH IS FORECAST TO CROSS THE NORTHERN ROCKIES AND AMPLIFY OVER THE NORTHERN AND CENTRAL PLAINS LATE SUNDAY INTO MONDAY. EXPECT SHOWERS AND THUNDERSTORMS TO DEVELOP IN ADVANCE OF THIS WAVE...AS WELL AS IN ADVANCE OF A SECONDARY TROUGH HOT ON THE HEELS OF THE FIRST. SOME ACTIVITY MAY BE POSSIBLE IN THE WEAK WARM ADVECTION REGIME IN ADVANCE OF THE SYSTEM AS WELL BUT WOULD TEND TO BE MORE ISOLATED. UPPER LEVEL WIND FIELDS WILL BE A BIT STRONGER AS THIS SYSTEM COMES THROUGH AND MAY BE SUFFICIENT FOR MORE ORGANIZED THUNDERSTORM ACTIVITY... BUT THE DETAILS OF THE SETUP FOR THIS SYSTEM ARE STILL QUITE FUZZY. AS THE UPPER WAVE PUSHES ACROSS THE GREAT LAKES REGION...LONGER RANGE MODELS HINT AT QUICK RESPONSE RIDGING INTO THE REGION WITH THE SFC FRONT AND PRECIP PUSHING SOUTH. IF THIS FORECAST HOLDS TRUE...WOULD EXPECT A WARMING TREND WITH TEMPS CLIMBING INTO THE 90S ONCE AGAIN BY THE MIDDLE OF NEXT WEEK. MUCH OF THIS WILL HINGE ON THE STRENGTH OF THE SHORT WAVE TROUGH AND ITS ABILITY TO PUSH THE SFC FRONT SOUTH INTO OKLAHOMA...AS A WEAKER FRONTAL SOLUTION WOULD RESULT IN GREATER PRECIP CHANCES OVER THE CWA. BARJENBRUCH && .TOP WATCHES/WARNINGS/ADVISORIES...NONE. &&
