What happened

The episode as NWS CLE wrote it up.

The combination of a surface boundary and a surge of warm, moist air helped to initiate convective thunderstorms during the early afternoon hours of July 22nd. Widespread activity fired up across the area and persisted through the afternoon and early evening hours. Recent heavy rainfall and saturated ground across the forecast area set the stage for flash flooding. Thunderstorms moved slowly across the area with heavy rainfall. Some locations saw as much as 3 to 4 inches of rainfall in an 60 to 90 minutes. As areal coverage of the thunderstorms increased later that afternoon, a second round of thunderstorms hit some locations, resulting in rapid runoff and more flash flooding.

What forecasters said that day

The local office's own words before the first event, 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 the first event at Jul 22, 11:56 AM EST, 49 minutes earlier.

Area forecast discussion, Jul 22, 11:56 AM EST, 49 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CLEVELAND OH
1256 PM EDT FRI JUL 22 2011

.SYNOPSIS...
HEAT AND HUMIDITY WILL CONTINUE TODAY AS A FRONTAL BOUNDARY JUST
NORTH OF THE AREA GRADUALLY MOVES SOUTH OVER THE AREA. THIS FRONT
WILL LINGER OVER THE AREA THROUGH THE UPCOMING WEEKEND. A COLD
FRONT IS EXPECTED TO MOVE ACROSS THE AREA EARLY NEXT WEEK PUSHING
THE HOT AND HUMID AIRMASS AWAY FROM THE REGION.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
UPDATED FOR DEVELOPING THUNDERSTORMS.

UPDATED FOR UPGRADE TO EXCESSIVE HEAT WARNING SOUTH AND WEST.
DEWPOINTS A BIT HIGHER THAN EXPECTED EARLIER AND THAT SHOULD PUT
THE HEAT INDEX OVER THE TOP OF ADVISORY CRITERIA.

PREVIOUS UPDATE...
MCS OVER NERN IL APPEARS TO BE MOVING LARGELY DUE EAST. CONCERNED
HOWEVER THAT THERE WILL BE SOME DEVELOPMENT ON THE SOUTH SIDE OF
THE MCS OR SOUTHEAST OF THE MCS ALONG AN OUTFLOW/COLD FRONT
INTERACTION. BEST THETA E ADVECTION GRADIENT AND VARIOUS
THUNDERSTORM PARAMETERS TRENDING TOWARD THIS SCENARIO OF BRINGING
THUNDERSTORMS INTO NWRN OH MID/LATE AFTERNOON. FOR NOW WILL
GO/CONTINUE WITH HIGH CHANCE POPS BUT WILL CHANGE FROM CHANCE TO
"SCATTERED" WORDING AND CONTINUE TO MONITOR FOR THIS TO
DEVELOP/EVOLVE.

PREVIOUS...
MADE ONLY MINOR ADJUSTMENTS TO TEMP AND DEWPOINT GRIDS WITH THIS
UPDATE. CONVECTION OFF TO THE WEST HAS DIMINISHED OVER SOUTHERN
MICHIGAN AS ANTICIPATED KEEPING NW OH DRY THIS MORNING. SOME
DEBRIS CLOUDS MOVING INTO NW OH THOUGH AS INDICATED...AND WILL
ALSO WATCH PROGRESS FOR SHRA/TS NEAR AND WEST OF ORD THIS MORNING.
PREVIOUS DISCUSSION BELOW.

HOT AND HUMID CONDITIONS WILL CONTINUE AGAIN TODAY...BUT THERE ARE
SOME ADDITIONAL CONCERNS TODAY COMPARED WITH YESTERDAY.
FIRST...TEMPS THIS MORNING WILL START IN THE UPPER 70S TO LOWER
80S WHICH WILL PROVIDE A GOOD OPPORTUNITY FOR LOCATIONS TO CLIMB
INTO THE 90S AGAIN TODAY. A FRONTAL BOUNDARY LOCATED OVER SOUTHERN
LAKE ERIE FROM NEAR ERI TO TOL WILL ONLY GRADUALLY SAG SOUTH OVER
THE AREA THROUGH TODAY. WINDS HAVE ALREADY TURNED WEST OR NW THIS
MORNING NEAR LAKESHORE AREAS OF NW PA AND OH. GIVEN THE GOOD START
THESE AREAS WILL HAVE A GOOD SHOT OF BREAKING 90 BUT THE FLOW OFF
THE LAKE WILL INHIBIT TEMPS RISES ESPECIALLY THIS AFTERNOON.
FURTHER TO THE SOUTH ESPECIALLY ACROSS SOUTHEAST AREAS FROM CAK TO
YNG TEMPS ARE EXPECTED TO ONCE AGAIN CLIMB WELL INTO THE 90S. WITH
THE FRONT EVEN CLOSER TODAY DO NOT THINK DEWPOINTS ACROSS CENTRAL
AND SOUTHERN AREAS WILL BE ABLE TO DROP MUCH THIS AFTERNOON
KEEPING THEM IN THE LOWER TO MID 70S. NORTHERN AREAS MAY SEE A
SLOW FALL TO THE LOWER 70S WITH NW OH HAVING THE BEST CHC OF DPTS
DROPPING BELOW 70. WITH THE INCREASE IN PROBABILITY OF TEMPS AND
DEWPOINTS ESPECIALLY ACROSS SOUTHEAST AREAS HAVE EXPANDED THE
HEAT ADVISORY FOR AREAS FROM CAK TO YNG. KEPT OUT IMMEDIATE
LAKESHORE AREAS OF NE OH AND NW PA.

REGARDING CONVECTION TODAY...POPS HIGHLY VARIABLE BETWEEN MAV AND
MET GUIDANCE. AFTER LOOKING AT VARIOUS MODELS INCLUDING EARLIER
RUNS OF THE HRRR EXPECTING CURRENT CONVECTION OVER SRN LAKE MI
THIS MORNING TO PUSH JUST NORTH OF TOL. HOWEVER...ADDITIONAL
SHRA/TS MOVING ALONG THE FRONT FURTHER WEST WHICH WILL PROGRESS
EAST TOWARD THE AREA THIS MORNING. NOT COMPLETELY CONFIDENT THIS
ACTIVITY WILL NECESSARILY MOVE INTO NW OH...BUT RATHER WITH THE
FRONTAL BOUNDARY SAGGING SOUTH COMBINED WITH A WEAKENING CAP AND
GOOD CAPE AND LI/S THINKING THERE COULD BE SCATTERED DEVELOPMENT
MIDDAY AND THROUGH THE AFTERNOON. EXPECTING THIS ACTIVITY TO BE
CONFINED MAINLY ACROSS WESTERN AREAS WITH A PUSH EASTWARD TOWARD
CLE-CAK POSSIBLE NOT UNTIL LATE AFTERNOON OR EVENING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
WITH THE FRONTAL BOUNDARY OVER THE AREA TONIGHT AND CONTINUING
INTO THE WEEKEND EXPECTING AT LEAST SLIGHT CHC/S FOR SHOWERS AND
THUNDERSTORMS THROUGH THE PERIOD. FOR TONIGHT POPS DECREASE QUITE
A BIT ACROSS THE AREA BUT RELUCTANT TO GO COMPLETELY DRY FOR THE
AREA AS THERE IS A POSSIBILITY OF LEFTOVER ACTIVITY PUSHING INTO
EASTERN AREAS. SIMILAR SITUATION FOR SATURDAY ACROSS THE AREA WITH
THE FRONTAL BOUNDARY. BY THIS POINT IT IS DIFFICULT TO TIME ANY
POSSIBLE UPPER LEVEL SHORTWAVES THAT MAY BE MOVE ALONG THE FLOW TO
HELP DEVELOP SHOWERS AND THUNDERSTORMS OVER ANY PARTICULAR AREA.
MET GUIDANCE POPS LEAN QUITE A BIT HIGHER THAN MAV NUMBERS SO
MAINTAINED CHC POPS ESPECIALLY GOING INTO SATURDAY NIGHT AND
THROUGH SUNDAY. THE COLD FRONT BRINGING RELIEF TO THE AREA IS
EXPECTED TO MOVE THROUGH ON MONDAY THEREFORE THE CHANCES OF
SHOWERS AND THUNDERSTORMS WILL PERSIST THROUGH EARLY MONDAY NIGHT
ACROSS THE AREA. AS FOR TEMPS THE EXACT PLACEMENT OF THE FRONTAL
BOUNDARY WILL BE AN ISSUE FOR SATURDAY AND SUNDAY AS EVEN A LIGHT
NORTHERLY WIND OFF THE LAKE WILL IMPACT TEMPS. WHILE DEWPOINT WILL
REMAIN AT LEAST IN THE UPPER 60S TO LOWER 70S THROUGH MUCH OF THE
PERIOD...GOING INTO THE WEEKEND ADDITIONAL CLOUD COVER AND THE
INCREASED CHANCES OF SHOWERS/TS IN THE AREA WILL HELP TO KEEP
TEMPS A BIT LOWER.

&&

.LONG TERM /TUESDAY THROUGH THURSDAY/...
THE SURFACE HIGH SHOULD BUILD SOUTH ACROSS THE AREA BY TUESDAY. IT
MAY NOT BE THE MOST REFRESHING/COOL HIGH PRESSURE WE HAVE SEEN BUT
IT WILL DROP TEMPERATURES BACK TO NEAR NORMAL AND DEWPOINTS DOWN
TOWARD 60 OR THE 50S...SO IT WILL SEEM A LOT MORE COMFORTABLE.

THE COOL DOWN APPEARS AS IF IT WILL BE SHORT LIVED AS THE RIDGE
ALOFT IS PROGGED TO BUILD THE SECOND HALF OF THE WEEK. TEMPERATURES
SHOULD REBOUND AS SOON AS WE GET ON THE BACK SIDE OF THE HIGH AND
THE RETURN SOUTH FLOW DEVELOPS. WILL FORECAST TEMPERATURES BACK UP
TOWARD 90 LATE IN THE WEEK. SOME OF THE MODELS HINT THAT WE MAY HAVE
TO DEAL WITH WARM ADVECTION THUNDERSTORMS BY WEDNESDAY NIGHT AND
THURSDAY. WILL KEEP A LOW POP (SLIGHT CHANCE FOR THE NORTHERN
COUNTIES) FOR NOW AS THERE IS NOT MUCH CONFIDENCE THIS FAR IN
ADVANCE.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
A WEAK COLD FRONT NEAR THE SOUTH SHORE OF LAKE ERIE WILL BECOME
NEARLY STATIONARY TODAY AND MAY BEGIN DRIFTING BACK NORTH AS A
WARM FRONT AS EARLY AS THIS AFTERNOON OR EVENING. A WEAK WAVE ON
THE FRONT NEAR CHICAGO MOVING EAST WILL BRING A DECENT CHANCE OF
SHOWERS/STORMS ACROSS NORTHWEST OHIO THIS AFTERNOON. STILL NOT
SURE HOW FAR EAST THE SHOWERS/STORMS WILL SPREAD. THERE ARE
INDICATIONS THAT THE SHOWERS/STORMS THAT DEVELOP WILL MOVE OFF TO
THE SOUTHEAST...PROBABLY MISSING EXTREME NE OH/NW PA...BUT NOT
REAL CONFIDANT ON THIS. WILL MENTION TEMPO SHOWERS/STORMS AT KTOL
KFDY AND KMFD WITH A CHANCE AT KCLE KCAK AND KYNG LATER AND KEEP
KERI DRY TODAY.

OUTLOOK...NON-VFR AT TIMES THROUGH MONDAY MORNING IN
SHOWERS/STORMS AND EARLY MORNING FOG/HAZE.

&&

.MARINE...
THE WEAK COLD FRONT WILL SLIDE ACROSS LAKE ERIE EARLY THIS MORNING
WITH A WIND SHIFT FROM THE NORTHWEST. THE FRONT WILL BECOME
STATIONARY SOMEWHERE NEAR THE SOUTH SHORE OF LAKE ERIE. THE GRADIENT
WILL BECOME LIGHT TODAY AND ONSHORE FLOW MAY BECOME THE DOMINANT
WIND BY THIS AFTERNOON. THUNDERSTORMS ACROSS NORTHWEST OHIO AND
LOWER MICHIGAN MAY SNEAK OUT OVER THE WESTERN BASIN OF THE LAKE AND
MARINERS SHOULD BE ALERT TODAY.

THE WEAK FRONT WILL LIKELY DRIFT BACK NORTH AS A WARM FRONT SO THE
PREVAILING FLOW WILL RETURN FROM THE SOUTHWEST FOR MUCH OF THE
WEEKEND. THE GRADIENT WILL PROBABLY BE LIGHT ENOUGH THAT
ONSHORE/OFFSHORE FLOW MAY CONTINUE IN MANY AREAS.

A STRONGER COLD FRONT IS EXPECTED LATE SUNDAY NIGHT/EARLY MONDAY
WHICH SHOULD VEER THE WIND TO THE NORTHWEST AND EVENTUALLY THE NORTH
AND NORTHEAST MONDAY AND TUESDAY. WE WILL HAVE TO WAIT AND SEE JUST
HOW THE STRONG THE GRADIENT IS AS THE SURFACE HIGH PRESSURE BUILDS
IN...OFTEN THE NORTH FLOW CAN MAKE THE LAKE CHOPPY.
