AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE ST LOUIS MO 638 AM CDT FRI AUG 25 2006 .DISCUSSION... THE LATEST GUIDANCE IS ALL POINTING TO A RATHER WET AND ACTIVE WEATHER PATTERN AS A SLOW MOVING WEST-EAST ORIENTED FRONT SAGS THROUGH THE AREA OVER THE NEXT 3-4 DAYS. THIS SHOULD BRING US MUCH NEEDED RAINFALL...HOWEVER BEFORE ALL IS SAID AND DONE SOME AREAS COULD SEE LOCALLY HEAVY RAINFALL IN A SHORT PERIOD. PINNING DOWN THE DETAILS OF THIS FCST IS THE MOST DIFFICULT TASK AS BOTH THE GFS AND NAM-WRF APPEAR TO BE SUFFERING FROM CONVECTIVE FEEDBACK AT VARYING POINTS IN THE FCST CYCLE. IN THE NEAR TERM...THUNDERSTORMS HAVE BLOSSOMED OVER PORTIONS OF NW MO AND ERN KS SINCE 06Z IN ASSOCIATION WITH A 35+ KT SWLY LLJ. THIS ACTIVITY IS BECOMING INCREASINGLY ORGANIZED WITH TIME AND APPEARS TO BE BEST FOCUSED ON THE LEADING EDGE OF THE ELEVATED INSTABILITY. THE QUESTION IS JUST HOW FAR EAST AND SOUTH THE ACTIVITY WILL PUSH AND DEVELOP BOTH THIS MORNING AND LATER TODAY. THE LATEST RUC ANALYSIS DATA IS INDICATING DRIER AND RELATIVELY STABLE AIR LOCATED ACROSS CNTRL MO EWD INTO ILLINOIS ATTM. HOWEVER THE FCST FROM BOTH THE RUC AND WRF-NAM SHOW THE LLJ VEERING TO MORE WLY AFT 12Z WHICH TRANSPORTS THIS HIGHER THETAE/UNSTABLE AIR EWD INTO CNTRL AND NE MO. IF THIS IS INDEED THE CASE IT WUD ARGUE FOR THESE STORMS IN SOME STATE TO PUSH INTO AT LEAST NW PTNS OF THE CWA. ALL OF THE MODEL GUIDANCE ALSO GENERATES PCPN IN THIS REGION. I HAVE BOOSTED POPS INTO THE HIGH CHC RANGE IN THE AFOREMENTIONED AREA AND CUT TEMPS A TAD WITH THIS IN MIND. FOR TONIGHT INTO MONDAY THE MAIN SHOW SHOULD BE CONCENTRATED ALONG AND NORTH OF THE WEST-EAST FRONT AS A PERSISTENT SWLY LLJ REMAINS FOCUSED ALONG THE SLOPED FRONTAL ZONE. A NUMBER OF ROUNDS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED. MOISTURE CONTENT WILL BE HIGH AND WARM CLOUD DEPTHS RELATIVELY DEEP WHICH SHOULD ENHANCE PCPN EFFICIENCY. IF WE GET SOME PRONLONGED TRAINING THEN WE COULD GET INTO A FLOOD THREAT. THE POTENTIAL FOR HEAVY RAINFALL WILL BE ADDRESSED IN THE HWO. THE THREAT OF RAIN SHOULD FINALLY PUSH SE OF THE AREA ON TUESDAY AS THE MAIN UPPER LEVEL TROF MOVES EAST INTO THE OH VLY REGION. GLASS && .AVIATION... FOR THE 12Z TAFS...CLUSTER OF STORMS OVR THE NWRN QUARTER OF MO WILL PUSH EWD THRU COU EARLY THIS MRNG AND POSSIBLY INTO UIN DURING THE MID-LATE MRNG HRS. THESE STORMS WILL LIKELY WKN AS THEY MOVE EWD THRU THE WRN PTN OF THE CWA AS THE ATMOSPHERE IS MORE STABLE OVR THE ERN PTN OF THE CWA...ESPECIALLY S AND E OF STL. THIS CLUSTER OF STORMS OR SMALL MCS SHOULD LEAVE AN OUTFLOW BNDRY ACRS THE CWA WHICH SHOULD BE A FOUCS FOR NEW CONVECTIVE DEVELOPMENT THIS AFTN INTO THE EARLY EVNG HRS. WILL MENTION A PROB30 GRP OF TSRA IN ALL THE TAF SITES FOR THE LT AFTN INTO THE EARLY EVNG HRS. GKS && .LSX WATCHES/WARNINGS/ADVISORIES... MO...NONE. IL...NONE. && WFO LSX
