NWS Topeka, KS wrote its last area forecast discussion before the first event at Jun 20, 2:45 AM CST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 345 AM CDT TUE JUN 20 2006 .DISCUSSION... THIS MORNING WATER VAPOR SATELLITE IMAGERY LOOP SHOWED A BROAD UPPER RIDGE OVER THE CENTRAL CONUS WITH AN UPSTREAM TROUGH MOVING EAST ACROSS THE UPPER GREAT BASIN. AHEAD OF THE GREAT BASIN 5H TROUGH A LARGE COMPLEX OF THUNDERSTORMS WERE LOCATED OVER SD. A MINOR 5H TROUGH WAS MOVING AROUND THE BROAD UPPER RIDGE ACROSS NORTH CENTRAL KS. WEAK SYNOPTIC SCALE LIFT AHEAD OF THE WEAK 5H TROUGH COMBINED WITH WAA PROBABLY HAS LEAD TO THE CONTINUATION OF A SMALL THUNDERSTORM COMPLEX ACROSS THE NORTHWEST AND WESTERN COUNTIES OF THE CWA THIS MORNING. THE SCATTERED THUNDERSTORMS WILL MOVE EAST INTO A DRIER 850-700MB AIRMASS AND SHOULD DISSIPATE BEFORE 10AM. I PLACED CHANCE POPS FOR THIS MORNING ACROSS THE CENTRAL COUNTIES WITH SLIGHT CHANCE POPS EAST ACROSS NORTHEAST KS AND PORTIONS OF EAST CENTRAL KS...JUST IN CASE ANY LEFT OVER SHOWERS DO MAKE IT INTO THE EASTERN COUNTIES OF THE CWA. THE GREAT BASIN 5H TROUGH WILL MOVE EAST TODAY AND FLATTEN THE BROAD 5H RIDGE ACROSS THE PLAINS. THE UPPER FLOW OVER THE CENTRAL AND NORTHERN HIGH PLAINS WILL VEER AND INCREASE. THE WESTERLY FLOW OVER THE ROCKY MOUNTAINS WILL LEAD TO DEEPENING SFC/850MB TROUGH OVER WESTERN KS. THE NAM SHOWS 850MB WINDS INCREASING TO 50KTS ACROSS THE SOUTHWEST AND WEST-CENTRAL COUNTIES OF THE CWA TODAY. AFTER 10AM THE BOUNDARY LAYER SHOULD MIX TO THE 850MB LEVEL AND TRANSPORT THESE HIGHER 850MB WINDS TO THE SURFACE DURING THE LATE MORNING AND EARLY AFTERNOON HOURS. THEREFORE I PLACED A WIND ADVISORY IN EFFECT FROM NOON THROUGH 700 PM SOUTH AND WEST OF A CONCORDIA...TO MANHATTAN...TO COUNCIL GROVE LINE. HIGH TEMPERATURES WILL BE VERY WARM TODAY WITH HIGHS IN THE MID TO UPPER 90S ACROSS MUCH OF THE CWA. A STRONG CAP SHOULD PREVENT THUNDERSTORMS FROM DEVELOPING THIS AFTERNOON. BOTH THE NAM AND GFS SHOW UPSLOPE STORMS DEVELOPING THIS AFTERNOON OVER EXTREME NORTHEAST CO AND WESTERN NE. THESE STORMS MAY CONGEAL INTO A COMPLEX OF STORMS/MCS AND MOVE EAST ACROSS NORTHERN KS AND MUCH OF NE THROUGH THE NIGHT. I PLACED CHANCE POPS ACROSS THE NORTHERN COUNTIES WITH A SLIGHT CHANCE ACROSS THE CENTRAL COUNTIES FOR LATE TONIGHT. THE UPPER FLOW WILL BE 30 TO 40 KTS FROM THE WEST...THUS I DONT THINK THERE WILL BE MUCH SOUTHWARD PROPAGATION OF TONIGHT THUNDERSTORM COMPLEX. THERE IS A CHANCE THE THUNDERSTORM COMPLEX TONIGHT MAY STAY NORTH OF THE KS BORDER. AS THE GREAT BASIN 5H TROUGH MOVES ACROSS THE NORTHERN PLAINS LATE THIS AFTERNOON AND TONIGHT...LOW-LEVEL CAA WILL CAUSE A COLD FRONT TO PUSH SOUTHWARD INTO THE NORTHERN CWA ON WEDNESDAY. SURFACE CONVERGENCE AHEAD OF THE FRONT WILL PROVIDE A LIFTING MECHANISM FOR THUNDERSTORMS TO DEVELOP AHEAD OF THE FRONT ACROSS THE NORTHERN CWA WEDNESDAY AFTERNOON. THESE STORMS WILL SLOWLY BUILD SOUTHEAST ACROSS THE CWA AS OUTFLOW FROM THE THUNDERSTORMS PUSH THE FRONT FARTHER SOUTH ACROSS THE CWA. BOTH THE GFS AND NAM SHOW A COMPACT 5H TROUGH EMBEDDED IN THE ZONAL FLOW MOVING EAST ACROSS KS LATE WED NIGHT INTO THURSDAY. THE 5H TROUGH WILL PROVIDE SYNOPTIC SCALE LIFT COMBINED WITH THE WAA/ISENTROPIC LIFT TO GIVE MOST OF THE CWA A GOOD CHANCE FOR RAIN AND THUNDERSTORMS EARLY THURSDAY MORNING INTO THURSDAY NIGHT. HOWEVER IF THE FRONT MOVES BACK NORTH AS THE WARM FRONT ON THURSDAY THE BEST CHANCES OF RAIN MAY SHIFT NORTH OF THE CWA. CLOUD COVER AND SCATTERED THUNDERSTORMS WILL KEEP TEMPERATURES COOLER ON THURSDAY WITH HIGHS ONLY REACHING INTO THE 80S. MOST OF THE SHOWERS AND THUNDERSTORMS MAY PUSH SOUTH OF THE CWA ON FRIDAY AS THE SFC FRONT MOVES SOUTH INTO NORTHERN OK. HIGH TEMPERATURES WILL CONTINUE TO BE A BIT COOLER NORTH OF THE FRONT. EXPECT HIGH TEMPERATURES IN THE 80S. THE EXTENDED FORECAST GRIDS...DAYS 5 THROUGH 7...LOOKED GOOD AND I DID NOT MAKE ANY CHANGES. && .TOP WATCHES/WARNINGS/ADVISORIES...WIND ADVISORY IN EFFECT FROM 12 NOON THROUGH 7PM FOR KSZ 020>022-034>036-037. &&
