What happened

The episode as NWS PAH wrote it up.

A building dome of high pressure aloft was responsible for near record high temperatures. Combined with high humidity, the heat index soared to between 105 and 110 on the afternoon of the 22nd and again on the afternoon of the 23rd. Actual air temperatures reached the mid to upper 90's both days. The heat caused some concrete roadways to buckle. The Dexter office of the Missouri Department of Transportation reported 26 incidents of highway concrete joints expanding and rupturing. Three of them were on U.S. Highway 60 west of Dexter in Stoddard County. Three others were on Highway 25 in the Dexter and Bloomfield areas.

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 Paducah, KY wrote its last area forecast discussion before the first event at Jun 22, 2:53 AM CST, 8 hours 7 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
353 AM CDT MON JUN 22 2009

.DISCUSSION...
MAIN CONCERNS CONTINUE TO BE THE HEAT AND HUMIDITY AND WHERE/WHEN
TO PLACE SMALL POPS ACROSS THE AREA.

00Z MODELS ARE IN AGREEMENT AND HAVE BEEN PERSISTENT IN
RETROGRADING THE UPPER RIDGE THAT HAS CRANKED UP THE HEAT ACROSS
THE QUAD STATE FOR THE LAST WEEK. IN ADDITION...THE SURFACE RIDGE WILL
ALSO RETROGRADE. THE RESULT OF ALL OF THIS WILL BE TO BRING NORTHERLY
FLOW AT THE SURFACE AND ALOFT TO THE REGION BY THE END OF THE DAY
TODAY. THIS WILL CONTINUE THROUGH MUCH OF THE WORK WEEK.

THE IMPACT OF THIS CHANGE WILL BE TO TREND TOWARD LESS HEAT AND
HUMIDITY...AND A COMPLETELY DRY FORECAST BY WEDNESDAY. IN THE
MEANTIME...THE 00Z CYCLE OF THE MODELS IS INDICATING SOME POOLING
OF LOW-LEVEL MOISTURE ACROSS THE REGION TODAY INTO TUESDAY...AS
THE WINDS GRADUALLY BECOME NORTHERLY IN THE LOW LEVELS. WITH THE
UPPER RIDGE STILL DOMINATING THE AREA...TEMPERATURES WILL REACH
THE MIDDLE 90S OVER THE ENTIRE AREA TODAY...RESULTING IN HEAT
INDICES AVERAGING AROUND 105 LATE THIS AFTERNOON AND EARLY THIS
EVENING. THUS THE HEAT ADVISORY LOOKS GOOD FOR TODAY.

HOWEVER...CONSENSUS MODEL GUIDANCE HAS TEMPERATURES AND DEWPOINTS
EACH DROPPING A FEW DEGREES FOR TUESDAY...AS THE NORTHERLY FLOW
TAKES EFFECT. WITH TODAYS HEAT INDICES RIGHT AT ADVISORY
CRITERIA...IT IS UNLIKELY THAT WE WILL SEE HEAT INDICES HIGH
ENOUGH TO EXPLICITLY SUPPORT THE ADVISORY ON TUESDAY.
HOWEVER...TUESDAY WILL MAKE A FULL WEEK OF ABNORMALLY WARM AND
HUMID CONDITIONS...SO FOR NOW WILL KEEP THE ADVISORY IN PLAY FOR
TUESDAY DUE TO THE PROLONGED NATURE OF THIS HEAT WAVE.

AS FOR POPS...THE 20/21Z SREF SEEMED TO DO A PRETTY GOOD JOB OF
MAPPING POPS FOR SUNDAY AFTERNOON AND NIGHT...SO WILL FOLLOW THE
21/21Z SREF FOR POPS FOR TODAY THROUGH TUESDAY. HAVE INCREASED
POPS A BIT IN THE NORTHEAST TODAY...AND DECIDED TO CONTINUE THE
SLIGHT CHANCE POPS IN THE EAST TONIGHT THROUGH THE DAY TUESDAY.

ONLY MADE A FEW COSMETIC CHANGES TO THE FORECAST BEYOND WEDNESDAY
NIGHT.

&&

.AVIATION...
GENERALLY CLEAR SKIES AND LIGHT WINDS OVERNIGHT WILL PERMIT SOME
LIGHT FOG TO FORM FOR A FEW HOURS. SIMILAR TO THE PAST FEW
DAYS...DIURNAL CUMULUS CLOUDS WILL BUBBLE UP BY 18Z. ISOLATED STORMS
WILL AGAIN POP UP AFTER 21Z...WITH THE GREATEST COVERAGE AGAIN IN
THE KEVV/KOWB AREAS. THE CHANCE FOR ISOLATED STORMS WILL BE A BIT
HIGHER MONDAY IN THE KPAH/KCGI AREAS AS AN UPPER LEVEL HIGH
RETROGRADES WESTWARD. ANY ISOLATED STORMS SHOULD DIE OFF AFTER
SUNSET MONDAY EVENING.
