AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 622 PM CDT SAT SEP 18 2010 ...UPDATE TO AVIATION... .DISCUSSION... FOR THE 00Z TAFS FOR KSGF/KJLN/KBBG...VFR CONDITIONS PREVAIL ACROSS THE AREA AT THIS TIME. A FRONTAL BOUNDARY IS CURRENTLY LOCATED ROUGHLY ALONG THE I-70 CORRIDOR WITH THUNDERSTORMS OCCURRING ALONG THE FRONT. IN ADDITION...THERE EXISTS A LOCAL AXIS OF INSTABILITY ALONG A KRCM-KHFJ-KROG LINE THAT IS SETTING OFF MAINLY SHOWERS AND AN ISOLATED THUNDERSTORM. HOWEVER...AS THIS ACTIVITY MOVES OFF THE AXIS IT DISSIPATES RATHER QUICKLY. EXPECT THE SHOWER AND THUNDERSTORM ACTIVITY LOCALLY TO ABATE TOWARD SUNSET. ACTIVITY ALONG FRONTAL BOUNDARY COULD BECOME MORE LINEAR LATER THIS EVENING...PER SPC DISCUSSION...AND MAY AFFECT THE KAIZ AND KVIH AREAS. OVERNIGHT...WITH LIGHT WINDS AND MOIST CONDITIONS PRESENT...EXPECT TO SEE AREAS OF MVFR FOG TO DEVELOP ACROSS THE AREA FROM 06Z ONWARD. ONCE FOG DISSIPATES AROUND 15Z...EXPECT VFR CONDITIONS THROUGH THE REMAINDER OF THE PERIOD WITH LIGHT SOUTHEAST WINDS. GAEDE && .PREV DISCUSSION... /ISSUED 249 PM CDT SAT SEP 18 2010/ MAIN FOCUS IN THE NEAR SHORT TERM WILL BE WITH CONVECTIVE PRECIPITATION CHANCES AND SEVERE WEATHER CHANCES THROUGH THIS EVENING. CU FIELD HAS DEVELOPED NICELY OVER THE PAST HOUR ACROSS WESTERN MISSOURI AND SOUTH CENTRAL KANSAS. OUTFLOW BOUNDARY FROM PREVIOUS CONVECTION HAS ALMOST STALLED ALONG THE NORTHERN CWA BORDER WITH WELL DEFINED COLD FRONT LOCATED FROM CENTRAL INTO NORTHEAST KANSAS AND ALONG THE I70 CORRIDOR IN MISSOURI. SURFACE MOISTURE AXIS WAS LOCATED OVER EASTERN KANSAS INTO WESTERN MISSOURI. A COUPLE OF RADAR ECHOES ALREADY STARTING TO SHOW UP ALONG THE COLD FRONT IN NORTHEAST KANSAS AND ANOTHER ALONG THE OUTFLOW BOUNDARY JUST NORTH OF OUR CWA IN HENRY COUNTY. ML CAPES HAVE POOLED UP INTO THE 2500 TO 3000 J/KG RANGE ALONG THE OUTFLOW BOUNDARY ACROSS NORTHERN CWA. WHILE WIND SHEAR REMAINS FAIRLY WEAK...IT IS AROUND 30 KTS ALONG THE NORTHERN CWA SO COULD SEE A HAIL THREAT WITH THE STORMS THAT DEVELOP. NORTHERN CWA HAS RECENTLY BEEN INCLUDED IN A SEVERE THUNDERSTORM WATCH UNTIL 10 PM CDT. IF THUNDERSTORM CLUSTERS CAN FORM...MOTION WOULD TAKE THE CONVECTION MORE TO THE SOUTH INTO THE CWA. WOULD EXPECT ANY CONVECTION TO WEAKEN WITH LOSS OF DAYTIME HEATING LATER THIS EVENING. UPPER RIDGE BUILDS INTO THE AREA AND AMPLIFIES LATE SUNDAY INTO MONDAY AND WILL LIKELY SEE DIMINISHED THUNDERSTORM CHANCES WITH FRONTAL BOUNDARY SHIFTING TO THE NORTH. WARM TEMPERATURES ARE ALSO EXPECTED WITH HIGHS CLIMBING BACK INTO THE UPPER 80S TO LOW 90S FOR MOST LOCALES. BETTER CHANCES OF RAIN WILL ARRIVE LATE IN THE WEEK AS A FRONTAL BOUNDARY BEGINS TO PUSH THROUGH WITH UPPER RIDGE BUILDING BACK TO OUR WEST AND TROUGH DEVELOPING OUT EAST.
