AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 1227 PM CDT THU AUG 16 2007 ...UPDATED AVIATION... .DISCUSSION... MAIN CONCERN IS ONCE AGAIN THE HEAT. SURFACE BOUNDARY WAS NEARLY STATIONARY FROM STJ TO IRK WITH AND BAND OF AC ALONG AND NORTH OF THE BOUNDARY. A FEW LIGHT SHOWERS WERE NOTED WITHIN THIS BAND OF CLOUD COVER...AHEAD OF WEAK SHORTWAVES EMBEDDED IN THE WEAK WEST NORTHWEST UPPER FLOW. THE NAM HAS COME IN LINE WITH THE GFS IN KEEPING THE BOUNDARY NEARLY STATIONARY TODAY AND SAGGING IT SOUTH TO NEAR I-70 TONIGHT. THE CLOUD COVER ALONG WITH A FEW LIGHT SHOWERS WILL KEEP TEMPERATURES COOLER ACROSS NORTHERN MISSOURI...BUT AREAS ALONG AND SOUTH OF THE MISSOURI WILL ONCE AGAIN SEE HOT TEMPERATURES. DOWNSLOPE SOUTHWEST WINDS WILL NOT BE AS STRONG TODAY WITH MODEL GRIDS SUGGEST A LITTLE COOLING AT H8. MOISTURE WILL BE GENERALLY POOLED NORTH OF THE BOUNDARY WITH MINOR POOLING OF MOISTURE JUST SOUTH OF THE BOUNDARY.
