MRDWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Cleveland, OH wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 9, 2:40 PM EDT, 1 hour 41 minutes earlier.
Area forecast discussion, Jun 9, 2:40 PM EDT, 1 hour 41 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 240 PM EDT WED JUN 9 2004 .DISCUSSION... FRONT OVER CENTRAL LOWER MI IS SLOWLY MOVING SOUTH. EXTREME INSTABILITY ACROSS THE AREA WITH CAPES 3000-5000 J/KG. HOWEVER...WITH THE FRONT STILL IN CENTRAL MI...THE ONLY TRIGGER MECHANISM AT THIS TIME OVER NRN OH IS THE LAKE BREEZE. THIS MAY CHANGE THIS EVENING AS THE FRONT SAGS SOUTH. WITH THE INSTABILITY IN PLACE...WILL GO WITH CATEGORICAL POPS TONIGHT...ESPECIALLY SINCE THE FRONT DOES NOT MAKE IT THRU THE CWFA UNTIL THE DAY ON THU. AM A LITTLE CONCERNED ABOUT TRAINING OF ECHOS OVERNIGHT AS FRONT BECOMES PARALLEL TO THE MEAN FLOW AND A THETA-E RIDGE MOVES INTO THE AREA. WILL THEREFORE PUT SOME HVY RAIN IN THE ZONES FOR OVERNIGHT. WITH THE SLOWER MOVEMENT OF THE FRONT...WILL CONTINUE WITH LKLY MORNING POPS ACROSS THE ENTIRE AREA...WITH LKLY POPS ALL DAY ACROSS THE SOUTH AS THE FRONT DOES NOT MAKE IT THRU UNTIL AFTN. AM CONCERNED AGAIN ABOUT HVY RAIN...ESPECIALLY WHEN SEEING WHAT IS HAPPENING OVER E CNTRL LOWER MI ALONG THE FRONT THIS AFTN. WILL ALSO PUT HVY RAIN IN THE FCST FOR THE SRN HALF OF THE AREA AGAIN TMRW. NW PA WILL SEE DRY NORTHEASTERLY FLOW SO WILL TAPER OFF TO SMALL CHC POPS OVER THAT AREA. IN FACT...ERI MAY SEE SUNSHINE IN THE AFTN AS THE HIGH BUILDS INTO NY STATE. FRONT SLOWLY SAGS TO SRN OH THU NIGHT...HOWEVER THE GFS AND ETA SHOW ANOTHER S/WV MOVING INTO OHIO THU NIGHT. WL CONTINUE WITH CHC POPS ACROSS MUCH OF THE AREA...EXCEPT NW PA WHERE DRY NE FLOW WILL KEEP IT DRY. FRONT TRIES TO MOVE N FRI AND FRI NIGHT. WL GO WITH LKLY OVER THE SW 2/3 OF THE CWFA ON FRI. AGAIN...IT IS VERY POSSIBLE THAT ERI WILL STAY DRY WITH CONTINUED NE FLOW. HOWEVER...WL CONTINUE WITH SMALL CHC POPS. IN THE EXTENDED...NOT MUCH CHANGE PLANNED. NRN HALF OF THE COUNTRY IS PROGGED TO BE IN A MORE ZONAL TYPE FLOW WITH INDIVIDUAL SHORT WAVES MOVING THROUGH THE MEAN FLOW EVERY 24-36 HOURS. TOUGH TO TIME THE SHORT WAVES...SO THE FCST WILL CONTINUED RELATIVELY UNSETTLED. UNLIKELY THAT EVERY PERIOD WILL SEE PCPN...BUT AT THIS TIME IT IS TOUGH TO DETERMINE THE EXACT TIMING. BEST CHC OF PCPN LOOKS TO BE MONDAY/MON EVENING WHEN THE GFS AND ECMWF SHOW A STRONG COLD FRONT/UPR TROUGH MOVING THRU THE AREA. WL CONTINUE WITH A DRY FCST ON TUESDAY AS WK HIGH PRES BUILDS INTO THE REGION. MDLS START TO DIVERGE BY WED...BUT THE GENERAL IDEA IS TO DEEPEN A TROUGH OVER THE WESTERN LAKES TUE NIGHT AND WED. THIS SHOULD ALLOW FOR ANOTHER CHC OF TSRA IN THE AFTN AS THE TROUGH APPROACHES. NO MAJOR EXTREMES IN TEMPS FOR THE NEXT COUPLE OF DAYS...BUT WITH HEIGHTS ACROSS THE AREA GENERALLY AT OR ABV NORMAL...IT WOULD SEEM THAT TEMPS WOULD FOLLOW THE SAME TREND. WARMEST DAYS OVER THE WKND. && .CLE WATCHES/WARNINGS/ADVISORIES... OH...SEVERE THUNDERSTORM WATCH UNTIL 6 PM. PA...SEVERE THUNDERSTORM WATCH UNTIL 6 PM. && MRD
