AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 326 PM CDT FRI AUG 17 2007 .DISCUSSION... WEAK FRONTAL BOUNDARY THAT PUSHED THROUGH THE AREA YESTERDAY IS NOW STRETCHING FROM SOUTHEAST NEBRASKA THROUGH SOUTHWEST MISSOURI. DRIER DEWPOINTS STEADILY MAKING THEIR WAY SOUTHWEST ACROSS THE FORECAST AREA WITH TEMPERATURES IN THE UPPER 80S TO LOWER 90S. FORECAST FOCUS IS ON REMNANTS OF ERIN AND POTENTIAL FOR RAINFALL THIS WEEKEND. HAVE THROWN THE WRF MODEL RUN OUT AS IT CONTINUES TO HAVE POOR INITIALIZATION OF ERIN. GFS...NGM...ECWMF...AND CANADIAN MODEL ALL BRING SYSTEM ACROSS MISSOURI AND ILLINOIS SATURDAY NIGHT AND SUNDAY. FIRST SHOT OF UPPER LEVEL ENERGY BEGINS TO AFFECT THE AREA LATE TONIGHT AND SATURDAY MORNING FROM THE SOUTHWEST AS SURFACE WINDS BEGIN TO SWING AROUND TO THE SOUTH. WOULDNT BE SURPRISED TO SEE SOME ISOLATED SHOWER AND THUNDERSTORM ACTIVITY ACROSS THE WESTERN HALF OF THE CWA SATURDAY MORNING....WITH MORE SURFACE BASED CONVECTION DEVELOPING DURING THE AFTERNOON. THE MAIN RAIN EVENT SHOULD COMMENCE LATE SATURDAY NIGHT THROUGH SUNDAY EVENING AS RICH TROPICAL MOISTURE STREAMS INTO THE REGION FROM WHAT IS LEFT OF ERIN. MODEL CONSENSUS BRINGS THIS FEATURE UP THE I-44 CORRIDOR WITH LARGE SWATH OF QPF COVERING A LARGE PORTION OF THE CWA. GIVEN PRECIPITABLE WATER VALUES IN EXCESS OF 2 INCHES...PRECIPITATION SHOULD BE VERY EFFICIENT. HAVE ONCE AGAIN GONE WITH LIKELY IN THE FORECAST ON SUNDAY AS CONFIDENCE IS HIGH IN SIGNIFICANT RAINFALL OCCURRING WITHIN THE CWA. GIVEN TROPICAL NATURE OF PRECIPITATION HAVE DECIDED TO USE RAIN WITH ISOLATED THUNDER WORDING IN FORECAST. EXTENDED FORECAST...MONDAY THROUGH FRIDAY ANY IMPACTS OF ERIN SHOULD BE WELL EAST BY MONDAY AFTERNOON WITH TEMPERATURES RETURNING TO ABOVE NORMAL VALUES THROUGH THE REMAINDER OF THE WEEK. UPPER LEVEL PATTERN STILL INDICATES THAT A LARGE RIDGE WILL BUILD ACROSS THE SOUTHERN HALF OF THE NATION WITH BUILDING HEIGHTS ACROSS THE FORECAST AREA. THIS COUPLED WITH +20C 850MB TEMPERATURES SHOULD SPELL ANOTHER HOT AND HUMID WEEK WITH TEMPERATURES IN THE MIDDLE 90S. STILL TOO EARLY TO DETERMINE IF HEAT CRITERIA WILL BE MET NEXT WEEK...BUT BELIEVE 100+ HEAT INDICES EACH AFTERNOON ARE LIKELY. NEXT PRECIPITATION CHANCE AND COOL DOWN WILL LIKELY COME WITH A FRONT THAT IS ADVERTISED TO MOVE SOUTH ACROSS THE REGION LATE IN THE WEEK...BUT CONFIDENCE IN ANY ONE SOLUTION IS LOW AND THEREFORE HAVE KEPT THE EXTENDED FORECAST DRY AND TAILORED TEMPERATURES TOWARD CLIMATOLOGY ON NEW DAY 7 FORECAST. CVKING && .AVIATION... FOR THE 18Z TAFS...STILL IS SOME POTENTIAL FOR ISOLD TSRA OVER CNTRL AND SERN MO THIS AFTERNOON WHERE IS WILL BE UNSTABLE...BUT CHANCES WILL BE TOO SMALL TO WARRANT MENTION AT KCOU. HAVE VFR AND DRY CONDITIONS GOING THROUGH THE NEXT 24 HOURS...EXCEPT FOR THE POTENTIAL FOR ADDITIONAL FOG DEVELOPMENT AFT 09Z. DO EXPECT SURFACE WINDS TO BE STRONGER TONIGHT WHICH WILL FAVOR LOW CLOUDS VS. FOG. BEST LOCATION FOR FOG DEVELOPMENT WILL BE AGAIN AT QUINCY WHICH HAS HAD THE MOST RECENT RAINFALL...AND KSUS WHICH WILL HAVE THE LIGHTEST VARIABLE WINDS TONIGHT.
