The episode as NWS MPX wrote it up.
Temperatures soared in the Twin Cities, passing the 100-degree mark and breaking an all-time record for June 7. The National Weather Service recorded a temperature of 103 degrees at the Minneapolis-St. Paul International Airport. The previous record high for the day was 95 degrees in 2004. The high fell one degree short of the all-time June record of 104 degrees set on June 27th, 1934. This was the warmest day in the Twin Cities in almost 23 years, when July 31, 1988 had a high of 105 degrees. The temperature remained at or above 100 degrees from 1200 to 1800 CST.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN
1235 PM CDT TUE JUN 7 2011
.UPDATED FOR AVIATION DISCUSSION BELOW...
.DISCUSSION...
SUMMARY...A LOT GOING ON IN THE SHORT TERM WITH HOT AND WINDY
CONDITIONS EXPECTED THIS AFTERNOON. PRECIP CHANCES ARE PRETTY LOW
FOR MOST OF THE FORECAST AREA WITH WARM FRONT LIFTING NORTH AND
KEEPING THE FOCUS IN NORTHERN MN...WHERE THUNDERSTORM ACTIVITY
COULD BE SEVERE. A COUPLE CHANGES TO THE HEADLINES THIS
MORNING...WILL EXPAND THE HEAT ADVISORY WEST A TIER OF COUNTIES IN
MN BUT LEAVE THE TIMING THE SAME. NO CHANGE TO THE EXCESSIVE HEAT
WARNING FOR THE TWIN CITES...WHICH IS STILL IN EFFECT UNTIL
WEDNESDAY MORNING. FINALLY...THERE SEEMS TO BE ENOUGH SUPPORT FOR
A WIND ADVISORY IN PORTIONS OF SOUTH CENTRAL AND WEST CENTRAL MN
THIS AFTERNOON. THE FORECAST IS LARGELY DRY UNTIL THE THURSDAY
NIGHT THROUGH SATURDAY PERIODS.
AS OF SUNRISE THIS MORNING THE SURFACE WARM FRONT IS EXPECTED TO
EXTEND FROM NORTHERN WI THROUGH CENTRAL MN AND INTO FAR NORTHERN
SOUTH DAKOTA. AREA OF CONVECTION THIS MORNING IN NORTHERN MN IS
TIED TO THE 925-700MB BAROCLINIC ZONE...WITH A LINGERING
INSTABILITY GRADIENT ALSO IN PLACE. 850MB MOISTURE TRANSPORT HAS
BEEN INCREASING SINCE MIDNIGHT ACROSS MUCH OF THE AREA...BUT THE
STRONGEST TRANSFER OF MOISTURE AND BETTER CONVERGENCE IS STILL
PEELING BACK ACROSS THE DAKOTAS AND INTO MONTANA. THERE ARE A FEW
LIGHT ECHOES APPEARING IN FAR WEST CENTRAL MN THIS MORNING...BUT
HAVE A HARD TIME SEEING MUCH AT ALL IN THE WAY OF PRECIP DOWN THIS
WAY DURING THE DAYLIGHT HOURS. THE WHOLE COLUMN IS DRY AND EVEN
CLOUDS SHOULD BE HARD TO COME BY...SMOKE FROM THE FIRES IN NEW
MEXICO MAY BE THE ONLY THING TO BE FOUND IN THE SKY.
TODAY WILL BE A BLOW TORCH. CURRENT SURFACE LOW IN THE NORTHERN
PLAINS WILL MATURE AND DEVELOP EASTWARD IN RESPONSE TO POTENT
UPPER TROUGH ADVANCING FROM MONTANA INTO NORTH DAKOTA TODAY. 00Z
GUIDANCE TAKES A 992-994MB SURFACE LOW INTO NORTHWEST MN BY LATE
THIS AFTERNOON...SOMEWHAT OF A CLIMATOLOGICAL ABNORMALITY THIS
TIME OF YEAR. HARD TO IGNORE THIS LOW...THE ISOBAR PACKING...THE
VERY GOOD MIXING EXPECTED TODAY...DRY AIR IN THE COLUMN...AND THE
40KTS IN THE MIXED LAYER OFF THE SOUNDINGS. A WIND ADVISORY WILL
BE NEEDED FOR TYPICAL OPEN AREAS IN SOUTHERN AND WESTERN MN. NOT
TO SAY IT WILL NOT BE WINDY EVERYWHERE...FULLY EXPECT GUSTS OVER
30MPH ACROSS MOST OF THE FORECAST AREA TODAY. THE DRY AIR AND
FAVORABLE S-SW COMPONENT...ALONG WITH 850MB TEMPERATURES IN THE
LOWER 20S C...AND ABUNDANT SUNSHINE SHOULD MEAN WE CAN ACTUALLY GO A
COUPLE DEGREES HIGHER THAN WHAT WE OBSERVED YESTERDAY. HIGHS WERE AT
OR ABOVE RECORD LEVELS YESTERDAY...AND SHOULD EASILY GET THERE AGAIN
TODAY. MAV/MET GUIDANCE BRING THE TWIN CITIES METRO TO 95 F...BUT WE
WERE 97 YESTERDAY AND WITH THE MIXING EXPECTED TODAY...WE SHOULD
FLIRT WITH 100. EXPECT LOCATIONS IN SOUTH CENTRAL AND SOUTHEAST MN
TO REACH TRIPLE DIGITS. DEWPOINTS HAVE RECOVERED THIS MORNING...AND
WE FIND MANY LOCATIONS IN THE LOW TO MID 60S. HOWEVER...WE WILL MIX
OUT AGAIN TODAY AND WE SHOULD DROP INTO THE LOWER 50S AT MANY SPOTS.
THIS WILL KEEP THE HEAT INDICIES DOWN SLIGHTLY...BUT ALSO ALLOW THE
OBSERVED HIGHS TO CLIMB A FEW DEGREES HIGHER.
FOR TONIGHT...THERE ARE SMALL POPS IN THE FORECAST FOR LARGELY
SOUTHEAST MN AND WEST CENTRAL. APPEARS THAT LLJ TRIES TO FEED SOME
MOISTURE UP THIS WAY LATE TONIGHT AS IT BENDS EASTWARD. BETTER CHANCE
FOR PRECIP FOR ROUGHLY THE SAME AREA WEDNESDAY NIGHT AS THE
SURFACE TROUGH FINALLY PASSES THROUGH...BUT EVEN THE MOISTURE AND
FORCING ALIGN FURTHER TO THE SOUTHEAST AND FOCUS THE RAIN IN EASTERN
IA AND SOUTHERN WI.
DRY AND COOLER WEATHER ON TAP FOR THURSDAY WHEN HIGH PRESSURE
PUSHES THE SURFACE BOUNDARY SOUTH OF THE AREA. THIS SHOULD BE THE
FOCUS FOR SHOWERS AND THUNDERSTORMS IN IOWA...BUT PRECIP RETURNS
THURSDAY NIGHT INTO FRIDAY MORNING AS BOUNDARY ADVANCES BACK TO
THE NORTH. THIS IS ESPECIALLY TRUE FOR LOCATIONS IN FAR SOUTHERN
MN. SHORTWAVE ENERGY OUT OF THE ROCKIES ALSO APPEARS DURING THIS
WINDOW. THE TREND WILL BE FOR MUCH COOLER TEMPERATURES THURSDAY
THOUGH SATURDAY. ECMWF AND GFS STILL AT ODDS OVER THE STRENGTH AND
POSITION OF THE HIGH...THE ECMWF IS MUCH WETTER THAN THE GFS
FRIDAY AND SATURDAY. MORE WARMTH RETURNS SUNDAY AND MONDAY...BUT
NO MAJOR SYSTEMS LOOMING IN THE NEXT SEVEN DAYS AFTER THE
IMMEDIATE SYSTEM MOVES OUT.

.AVIATION.../18Z TAF ISSUANCE/
VFR CONDS THROUGHOUT PERIOD AS A WIND SHIFT AND COLD FRONT MOVES
THROUGH THE REGION. VERY WINDY AND HOT ACROSS THE AREA THIS
AFTERNOON WITH SOUTH/SOUTHWEST WINDS AHEAD OF DRY TROUGH MOVING
ACROSS EASTERN SOUTH DAKOTA NOW. AS THIS WORKS INTO THE AREA THIS
EVENING...WIND SWILL DECREASE AND SHIFT MORE SOUTHWEST. 12Z MODEL
RUNS INDICATING BETTER CHANCE OF SCT/ISOLD SHRA/TSRA ALONG THIS
BOUNDARY AS IT MOVES EAST AFTER 05Z WED. WILL MENTION VCSH/CB OVER
FAR EASTERN AREAS. THIS MOVES FAR ENOUGH EAST BY 15Z WED TO END THE
THREAT. COLD FRONT MOVES IN BEHIND THIS SYSTEM AND DROPS SOME CAA
STRATOCUMULS OVER NORTHWEST CWA DURING THE MORNING. SREF PROBS
INCREASE FOR POSSIBLE MVFR CONDS DEVELOPING AT KAXN AFTER 14Z WED.
WILL KEEP LOW END VFR FOR NOW AND SEE IF THIS TREND CONTINUES. GUSTY
NORTHWEST WIND SWILL DEVELOP BEHIND COLD FRONT MAINLY AFTER 15Z WED.
KMSP...VFR CONDITIONS THROUGHOUT FORECAST PERIOD. STRONG
SOUTH/SOUTHWEST WINDS AHEAD OF TROUGH OVER EASTERN DAKOTAS...WILL
GRADUALLY DIMINISH THIS EVENING. MODELS TREND INCREASING CHANCE OF
SHRA/TSRA DEVELOPING ALONG AHEAD OF THIS TROUGH LATER TONIGHT. WILL
MENTION VCSH FOR NOW. CONFIDENCE LOW ON ANY SIGNIFICANT DEVELOPMENT
OVER EAST CENTRAL MINNESOTA NOW. SECOND COLD FRONT WILL MOVE THROUGH
THE TOWARD 12Z WED...USHERING IN SOME MID CLOUDS AND INCREASING
NORTHWEST WINDS. MAY SEE SOME CUMULUS LATE MORNING/AFTERNOON AS
COLDER AIR ARRIVES.
