Area forecast discussion, Aug 27, 1:55 PM EST, 2 hours 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OHIO 255 PM EDT FRI AUG 27 2004 .SHORT TERM (TONIGHT THRU SUN) SLOW MOVING FRONTAL SYSTEM OVER THE MID MISSISSIPPI VALLEY WL CONT TO BE THE FOCUS OF THE FORECAST FOR THIS PERIOD. THE MODELS ARE IN DISAGREEMENT WITH THE MOVEMENT OF THIS SYSTEM THROUGH THE WARNING AREA. SEVERAL MESOSCALE CONVECTIVE SYSTEMS HAVE GENERATED IN ADVANCE OF THIS FRONT AND MAYBE HAVING AN IMPACT ON THE MODELS. BOTH THE GFS AND ETA DO NOT BRING THE FRONT THROUGH THE FORECAST AREA UNTIL SUNDAY. THE GFS IS FASTER WITH THE SYSTEM...HAVING THE FRONT CLEAR THE FORECAST AREA BY 00Z MON. THE ETA KEEPS THE FRONT LONGER CLEARING THE AREA 06Z-12Z MON. WHILE SUNDAY LOOKS LIKE A SURE BET FOR PCPN THE PERIODS IN BETWEEN ARE QUESTIONABLE. THE ATMOSPHERE IS VERY UNSTABLE AS LIS ARE -6 TO -7. THE PROBLEM IS A KICKER TO INITIATE THE PCPN. THE MODELS INDICATE SEVERAL SMALL WAVES TONIGHT AND SATURDAY BUT THESE WAVES MAY NOT BE REALISTIC. AN EXISTING BOUNDARY FROM THE CONVECTION LAST NIGHT IS MOVING THROUGH THE AREA ATM. THUNDERSTORMS ARE ALREADY DEVELOPING ALONG THIS BOUNDARY AND ARE EXPECTED TO CONTINUE THROUGH THE AFTERNOON AND EVENING. MOST LIKELY...THE POPS WILL REMAIN SCATTERED BUT IF THE PCPN BECOMES TO WIDESPREAD WE MAY HAVE TO ISSUE LIKELY POPS. I WL KEEP HIGH CHC POPS FOR SAT AND SAT NGT. THE HIGHER POPS WL BE TO THE WEST CLOSER TO THE FRONT. I AM STILL NOT SURE OF A FOCUSING MECHANISM FOR THE PCPN ON SAT AND GUIDANCE POPS SEEM REALLY HIGH. I ALSO BELIEVE THE TEMPS ON SAT WL BE SIMILAR TO TODAY. THE MODEL 850 MB TEMPS SHOW SOME COOLING BUT I THINK THIS IS UNREALISTIC. WITH SCATTERED PCPN ON SAT I EXPECT TEMPS TO BE NEAR MID 80S NOT UPPER 70S AS GUIDANCE SUGGESTS. && .LONG TERM (SUN NIGHT THROUGH FRIDAY) THE EXTENDED MODELS SHOW THAT MOST OF THE AREA IS IN FOR A FAIRLY DRY PERIOD THROUGH THE EXTENDED. SOME PCPN MAY LINGER SUN NGT AND EARLY MONDAY AS THE COLD FRONT PUSHES EAST BUT A LARGE RIDGE WILL BUILD OVER THE REGION ON MONDAY. THE GFS SHOWS A WEAK UPPER LEVEL SYSTEM MOVE THROUGH THE WARNING AREA TUESDAY DAY/NIGHT. HOWEVER...THE ATMOSPHERE IS VERY DRY AND PCPN IS NOT LIKELY. THE MODELS DO NOT HINT AT ANY OTHER SYSTEMS UNTIL LATE FRIDAY NIGHT. TEMPS LOOK TO BE NEAR CLIMATOLOGY. && .AVIATION (18Z-18Z)...
