AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE CLEVELAND OHIO 1030 AM EDT THU JUL 20 2006 .SHORT TERM (THIS AFTERNOON)... MAINLY COSMETIC CHANGES. WILL SPLIT FAR WESTERN GROUP INTO TWO...WILL KEEP OCCASIONAL IN FAR WEST AND THEN LIKELY FOR REST OF THAT GROUP. && .AVIATION(12Z-12Z)... THE MCS OVER INDIANA IS MOVING EAST WITH THE STRONGEST STORMS PUSHING SOUTH. HOWEVER...SOME OF THE PCPN WILL MAKE IT INTO THE WESTERN FORECAST AREA AFTER 10AM AND SHOULD DECREASE AS IT MOVES EAST. THE DEBRIS CLOUDS FROM THE MCS WILL OVERSPREAD THE AREA. THE FOG WILL BURN OFF BY 10 AM. AS THE MCS MOVES EAST THE PCPN SHOULD BECOME MORE SPOTTY. WE MAY HAVE TO WAIT UNTIL THIS EVENING FOR MORE ACTIVITY TO DEVELOP AHEAD OF COLD FRONT AND THE CLOUDS WILL HELP STABILZE THINGS...SEVERE THREAT IS ON THE EDGE. SOME FORECAST MODELS TRYING TO INDICATE LOW LEVEL MOISTURE AFTER FROPA...THUS INTRODUCED SOME MVFR CIGS. && .SHORT TERM (TODAY)UPDATE... PCPN OVER INDIANA MAY GET INTO NORTHWEST OHIO QUICKER THAN FORECAST...THUS UPDATED. ALSO PLENTY OF CLOUDS WILL BE OVER THE AREA FROM THE DECAYING MCS...THUS ADDED BECOMING MOSTLY CLOUDY. ALSO ADJUSTED TEMPERATURES DOWN. THIS EXTRA CLOUDS MAY HAVE DECREASE THE SEVERE THREAT. THE SEVERE THREAT WOULD BE AFTER 20Z AT THE EARLIEST. && .SHORT TERM(TODAY THROUGH FRIDAY NIGHT)... WATCHING MCS OVER IL. THE MAIN BULK SHOULD JUST MISS THE FORECAST AREA BUT SOME MAY GET CLOSE AND THIS WILL HAVE TO BE MONITORED. THE THICKNESS SEEMS TO INDICATE THAT IT SHOULD TRY TO DIVE SOUTH. OTHERWISE GFS SEEMS TO HAVE TOO MUCH CONVECTIVE FEEDBACK AND TRYING TO START THE PRECIPITATION TOO SOON. ALSO ALL THE CLOUD COVER FROM THE MCS MAY HELP KEEP THE INSTABILITY UNDER CONTROL...BECAUSE OF QUESTIONS WILL NOT MENTION SEVERE IN THE ZONES JUST THE HWO. THE WRF/NAM TRIES TO MOVE THINGS QUICKER THAN THE GFS THIS MAKES SENSE WITH THE CONVECTIVE FEEDBACK PROBLEMS ON THE GFS IT IS TOO SLOW. ATTM WILL HAVE SOME PCPN LINGER INTO FRIDAY AM IN THE EASTERN PORTION OF THE FORECAST AREA....OTHERWISE WILL LET THE HIGH PRESSURE BUILD IN. GUIDANCE TEMPERATURES OK. WILL HAVE TO MONITOR THE AMOUNT OF CLOUD COVER TODAY AS THAT COULD AFFECT THE TEMPERATURES. && .LONG TERM(SATURDAY-WEDNESDAY)... NO REAL CHANGES TO THE EXTENDED. STILL LOOKS LIKE A DECENT COOLDOWN FOR THE WKND. HAVE DISREGARDED THE NAM SOLN SHOWING PCPN ON SATURDAY...AS THE GFS ENSEMBLE MEMBERS AND OTHER MED RANGE MODELS DO NOT SUPPORT THIS. HAVE CONTINUED THE DRY FCST FOR THE WKND...ALTHOUGH THERE MAY BE SOME CLOUDS ESPECIALLY SATURDAY. THE GFS AND ECMWF CONTINUE TO SHOW AMPLIFICATION OF THE PATTERN ACROSS THE COUNTRY...WITH A STRONG RIDGE OVER THE WEST AND THE TROUGH OVER THE GREAT LAKES. THIS WILL ALLOW FOR BELOW NORMAL TEMPS IN THE 70S FOR THE WKND. THE FRONT SHOULD BECOME STATIONARY FAR ENOUGH SOUTH TO KEEP ANY PCPN OUT OF THE REGION UNTIL MONDAY NIGHT WHEN THE FLOW BECOMES FLATTER AND THE SFC FRONT MOVES BACK NORTH. THE MODELS SUGGEST THAT FRONT MAY BECOME STATIONARY OVER OHIO TUE AND WED WHICH MAY SERVE AS FOCUS FOR CONVECTION. WL THEREFORE INTRODUCE 30 POPS FOR THIS TIME PERIOD WITH TEMPERATURES RISING TO ABOVE NORMAL ONCE AGAIN. && .CLE WATCHES/WARNINGS/ADVISORIES... .OH...NONE. .PA...NONE. && SHORT TERM...OUDEMAN/KIELTYKA LONG TERM...MRD AVIATION...KIELTYKA
