What happened

The episode as NWS CLE wrote it up.

A stalled frontal boundary oriented west-east across central Ohio aided in the development of scattered thunderstorms during the afternoon hours. Most of the activity occurred over southern Ohio, but an isolated severe thunderstorm popped up over Knox County that afternoon.

What forecasters said that day

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
312 PM EDT THU JUL 7 2011

.SYNOPSIS...
HIGH PRESSURE SPREADING OVER THE AREA WILL WEAKEN SOME ON FRIDAY
THEN RESTRENGTHEN SATURDAY BEFORE SHIFTING TO THE EAST COAST SUNDAY.
A COLD FRONT SHOULD MOVE ACROSS THE REGION LATE MONDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY/...
HIGH PRESSURE OVER THE CWA WILL PROVIDE DRY CONDITIONS FOR MOST
PLACES. AN UPPER LEVEL TROUGH MOVING INTO THE AREA FROM THE NW MAY
PROVIDE ENOUGH SUPPORT TO MAKE A FEW SHRA/TSRA POSSIBLE IN THE FAR
SOUTHEASTERN COUNTIES WHERE SOMEWHAT BETTER MOISTURE LINGERS.

&&

.SHORT TERM /6 AM FRIDAY THROUGH SUNDAY NIGHT/...
THE CONTINUED PROGRESSION OF THE UPPER TROUGH ACROSS THE CWA WILL
MAINTAIN A CHANCE FOR SHRA/TSRA IN THE SE FRI INTO FRI EVE THEN THE
COMBINATION OF A WEAK COLD FRONT PUSHING SE TO MOVE OUT THE MOISTURE
AND THE UPPER TROUGH MOVING OFF TO THE SE WILL END THE THREAT OF
PRECIP.

HIGH PRESSURE SHOULD DOMINATE TO KEEP THE WEATHER DRY WELL INTO
SUNDAY. A RETURN FLOW WITH INCREASED RH EXPECTED TO START BY LATE
SUN AND CONTINUE SUN NIGHT. SOME LEFTOVER CONVECTION THAT DEVELOPS
NW OF THE AREA MAY BE ABLE TO HOLD TOGETHER TO SLIDE SE DOWN THE
WARM FRONTAL BOUNDARY AND MAKE A RUN AT THE EXTREME NW PART OF THE
CWA LATE SUN AND ANYWHERE NEAR LAKE ERIE SUN NIGHT. NOT SEEING MID
AND UPPER HEIGHTS FALLING SO WILL KEEP THE POP FOR THIS POSSIBILITY
ON THE LOW SIDE.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
THE MODELS HAVE BEEN CONSISTENT WITH THE NEXT COLD FRONT DUE ON
MONDAY. THE EXACT TIMING IS STILL IN QUESTION. THE 12Z GFS IS A
LITTLE FASTER THAN RECENT VERSIONS AND CLOSER TO THE ECMWF BUT THE
THERMAL/PRESSURE FIELDS ARE WEAK AND THERE COULD BE A PREFRONTAL
TROUGH. WILL JUST CONTINUE TO ADVERTISE A "CHANCE" OF SHOWERS/STORMS
ON MONDAY AND STICK WITH A WARM DAY WITH HIGHS WELL IN THE 80S TO
AROUND 90. IF THE TREND HOLDS FOR A FASTER FRONTAL PASSAGE WE HAVE
TIME TO SNEAK THE TEMPERATURES DOWN.

THE SURFACE HIGH PRESSURE SHOULD BUILD OVER EASTERN CANADA FOR MID
WEEK. WE WILL BE CLOSE TO THE BATTLE ZONE WITH THE WARM FRONT AND
THUNDERSTORM COMPLEXES BUT NORMALLY IN THIS PATTERN THERE IS ENOUGH
RIDGING THAT THE ACTIVITY TENDS TO STAY TO OUR WEST AND SOUTH. WILL
CONTINUE WITH A DRY FORECAST FOR MID WEEK WITH TEMPERATURES BACK TO
NEAR SEASONABLE NORMS.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
VFR WILL CONTINUE WITH MAINLY MID AND HIGH CLOUDS. CANNOT TOTALLY
RULE OUT A THUNDERSHOWER FROM KFDY TO KMNN TO CANTON LATE THIS
AFTERNOON OR EARLY THIS EVENING SINCE THE FRONT IS NEARLY
STATIONARY IN THIS AREA BUT THE TAF FORECASTS ARE DRY SINCE THE
CHANCES ARE QUITE LOW AT ANY GIVEN SITE. A WAVE ON THE FRONT COULD
BRING A FEW SHOWERS FRIDAY MORNING INLAND FROM LAKE ERIE BUT
CONDITIONS SHOULD REMAIN VFR.

OUTLOOK...NON-VFR IN SHOWERS/STORMS MONDAY.

&&

.MARINE...
HIGH PRESSURE OVER THE LAKE WILL WEAKEN A BIT ON FRIDAY AS LOW
PRESSURE SYSTEMS MOVE WELL TO THE NORTH AND SOUTH OF THE LAKE. HIGH
PRESSURE WILL REINFORCE OVER THE LAKE ON SATURDAY AND REMAIN IN
CONTROL THROUGH THE END OF THE WEEKEND. THE HIGH PRESSURE WILL
PROVIDE MAINLY LIGHT AND VARIABLE WINDS THROUGH SATURDAY WITH WINDS
TURNING TOWARD THE SOUTHEAST DURING SUNDAY. WINDS WILL TURN MORE
SOUTHERLY BY MONDAY AHEAD OF A WEAK COLD FRONT THAT IS EXPECTED TO
PUSH ACROSS THE LAKE MONDAY AFTERNOON AND EVENING. HIGH PRESSURE
WILL BUILD OVER THE LAKE BEHIND THE COLD FRONT AND MOVE OVER THE
LAKE FOR MIDWEEK. NO HEADLINES ARE ANTICIPATED OVER THE NEXT SEVERAL
DAYS.
