What happened

The episode as NWS DTX wrote it up.

A lake breeze kicked off a pulse severe storm in Oakland County to start things rolling on Tuesday, May 30th. With a very unstable airmass in place, additional strong thunderstorms were able to develop on the outflow boundaries from previous storms. This led to severe thunderstorm development propagating as far north as Huron County. At the same time, another line of severe storms, that had initially formed along a lake breeze off of Lake Michigan, tracked across the Tri-Cities area. There were numerous reports of large tree limbs and trees downed. Also, several hail reports were received, with the largest hail being reported as the size of quarters.

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 Detroit, MI wrote its last area forecast discussion before the first event at May 30, 9:10 AM EST, 1 hour 55 minutes earlier.

.UPDATE...

QUICK UPDATE SENT OUT TO BUMP UP POPS THIS MORNING...AS SHOWER AND
THUNDERSTORM ACTIVITY MOVING THROUGH THE TRI-CITIES/FLINT VICINITY
HAS HELPED UP FAIRLY WELL. ALSO...A THUNDERSTORM HAS POP UP ACROSS
THE THUMB REGION AND JUST SW OF LENAWEE COUNTY. NUMEROUS SHOWERS AND
THUNDERSTORMS STILL ON TRACK (EVERYWHERE) FOR THE AFTERNOON AS K
INDICES CONTINUE TO CLIMB INTO THE MID TO UPPER 30S. GOOD
INSTABILITY COUPLED WITH WEAK WIND FIELDS WILL PROVIDE AREAS OF
SURFACE CONVERGENCE...AS NOTED IN THE THUMB REGION THIS
MORNING...TRIGGERING ADDITIONAL ACTIVITY. THIS MORNING ACTIVITY
SHOULD LIMIT THE INSTABILITY JUST ENOUGH...GENERALLY CAPES 2500 J/KG
OR LESS...WHICH SHOULD MAKE THE PULSE SEVERE THREAT MINIMAL.

.AVIATION...

AN AREA OF THUNDERSTORMS HAS DEVELOPED THIS MORNING NEAR JXN
ALONG THE LEADING EDGE OF SOME DEEPER ATMOSPHERIC MOISTURE. THIS
LEADING EDGE OF HIGHER MOISTURE WILL REACH MBS AND FNT BETWEEN 15Z
AND 18Z...AND DTW/DET BETWEEN 18Z AND 21Z. AFTER THIS DEEPER
MOISTURE ARRIVES...THERE WILL BE THE RISK OF THUNDERSTORMS
BASICALLY AT ANY TIME DUE THE HIGH INSTABILITY PRESENT OVER THE
AREA. WILL KEEP A SHORT TEMPO GROUP IN THE TAFS BASICALLY DURING
THE TIME PERIOD AT WHICH THE NAM MODEL SHOWS THE BEST 850MB
MOISTURE CONVERGENCE AND SURFACE CONVERGENCE. THIS WILL BE LATE
AFTERNOON AND EARLY EVENING. THUNDERSTORMS TODAY WILL BE CAPABLE
OF PRODUCING VERY HEAVY RAINFALL WHICH WILL SEVERELY RESTRICT
VISIBILITY. FREQUENT LIGHTNING CAN ALSO BE EXPECTED FROM THE
STORMS.

.PREV DISCUSSION...ISSUED 347 AM EDT TUE MAY 30 2006

SHORT TERM...TODAY AND TONIGHT

THE LATEST WATER VAPOR LOOP AND 00Z UPPER AIR PLOTS SHOW AN UPPER
LOW OVER THE SASKATCHEWAN/MANITOBA BORDER AND A SUMMER-LIKE RIDGE
EXTENDING FROM THE EASTERN GULF OF MEXICO TO THE EASTERN GREAT
LAKES. ALSO SHOWN ON THE WATER VAPOR IS A PLUME OF DEEP MOISTURE
FROM THE MISSISSIPPI VALLEY TO THE WESTERN GREAT LAKES ON THE BACK
SIDE OF THE UPPER RIDGE AXIS. AT THE SURFACE...A COLD FRONT EXTENDS
FROM WESTERN LAKE SUPERIOR TO THE TEXAS PANHANDLE.

THE UPPER LOW WILL ROTATE INTO HUDSON BAY TONIGHT...FLATTENING THE
RIDGE AXIS OVER THE EASTERN GREAT LAKES AND ALLOWING THE SURFACE
COLD FRONT TO MAKE A GRADUAL PUSH EASTWARD INTO THE GREAT LAKES
REGION. 00Z UPPER AIR PLOTS AND NAM/GFS MODEL SOLUTIONS INDICATE THE
LEADING EDGE OF HIGHER MOISTURE BETWEEN 700 AND 500MB WILL RESIDE
JUST WEST OF THE FORECAST AREA THIS MORNING. THIS AXIS OF DEEPER
MOISTURE MAY ALLOW SOME SCATTERED CONVECTION TO DEVELOP THIS
MORNING...WHICH MAY IMPACT THE FAR WESTERN COUNTIES. THE DEEPER
MOISTURE WILL MOVE ACROSS SOUTHEAST MICHIGAN THIS AFTERNOON. MODEL
SOUNDINGS INDICATE A WEAKER MID LEVEL CAP PRESENT THIS AFTERNOON IN
COMPARISON TO PREVIOUS DAYS. 850MB MOISTURE CONVERGENCE AS WELL AS
SURFACE CONVERGENCE ALONG LAKE BREEZE BOUNDARIES AND THUNDERSTORM
OUTFLOW BOUNDARIES SHOULD ALLOW SCATTERED TO NUMEROUS COVERAGE OF
SHOWERS AND THUNDERSTORMS FROM LATE AFTERNOON THROUGH MID EVENING
ACROSS THE FORECAST AREA. MID LEVEL WIND FIELDS WILL REMAIN WEAK.
HOWEVER 0-1KM MIXED LAYER CAPE IS EXPECTED TO RANGE FROM 2-3K
J/KG...SO CAN NOT RULE OUT THE POSSIBILITY OF ISOLATED PULSE SEVERE
STORMS LATE TODAY. WITH PRECIPITABLE WATER VALUES RISING TO 1.7
INCHES BY EVENING AND WITH SLOW STORM MOTION...LOCALLY HEAVY
RAINFALL WILL ALSO BE POSSIBLE TODAY.

THERE SHOULD BE MORE CLOUD COVER TODAY THAN YESTERDAY GIVEN THE
DEEPER MOISTURE ADVECTION AND GREATER POTENTIAL FOR THUNDERSTORMS.
WILL THEREFORE LEAN TOWARD THE COOLER MAV MOS GUIDANCE FOR
HIGHS...BASICALLY 2-4 DEGREES COOLER THAN YESTERDAY. SURFACE
DEWPOINTS WILL STILL HOWEVER REMAIN WELL IN THE 60S TO NEAR 70. SO
IT WILL BE ANOTHER HOT AND HUMID DAY.

WILL LOWER POPS BACK INTO THE CHANCE/SCATTERED CATEGORY LATE TONIGHT
IN MOST AREAS AS THE SURFACE COLD FRONT AND STRONGER LIFT WILL
REMAIN JUST NORTHWEST OF THE FORECAST AREA. WITH LITTLE CHANGE IN
AIRMASS...TONIGHT WILL BE ANOTHER WARM AND MUGGY NIGHT.

LONG TERM...WEDNESDAY THROUGH TUESDAY

THE POTENTIAL FOR A HEAVY RAINFALL EVENT WEDNESDAY-THURSDAY
TIMEFRAME AS DEEP MOISTURE...TROPICAL...ACROSS THE REGION INTERACTS
WITH APPROACHING COOL FRONT AND DEPARTING UPPER LEVEL JET TO OUR
NORTH.  IT SEEMS WE ARE SETTING UP FOR NOT ONLY AN ACTIVE MID WEEK
PERIOD WITH CONVECTION BUT FLOODING AS WELL WITH LOCAL CHECK LIST A
BIT ALARMING.

THIS SLOW MOVING FRONTAL BOUNDARY IS EXPECTED TO REMAIN NEAR THE
REGION WEDNESDAY AND WEDNESDAY NIGHT UNTIL UPSTREAM SHORT
WAVE...CURRENTLY ENTERING THE FOUR CORNERS REGION...APPROACHES.  YET
THE EVOLUTION OF THIS WAVE IS STILL IN QUESTION AS BOTH THE NAM/GFS
SUGGEST THIS WILL BECOME MANUFACTURED ACROSS THE NORTHERN PLAINS
THEN DIVES SOUTHEAST ACROSS THE GREAT LAKES.  THE FACT THAT BOTH OF
THESE MODELS PICK UP ON THIS IS QUITE REMARKABLE BUT TIMING AN
ISSUE...OF COURSE.  NEVERTHELESS...THIS NCEP SUITE IS QUITE ALARMING
WITH FLOOD POTENTIAL FOR OUR NORTHERN 1/2-1/3 OF THE CWA AS THIS
REGION NOT ONLY HAS A SHOT TO HAVE A QUASI-LINEAR FRONT IN THE
VICINITY BUT PWATS CLIMBING WELL BETWEEN 1.70 AND 2.00 INCHES AND A
RELATIVELY WEAK WIND FIELD SOUTH OF THIS BOUNDARY.  IN THE UPPER
LEVELS...WE BECOME INFLUENCED BY A DEPARTING 90+KT JET WITH ENTRANCE
REGION DYAMANICS WEDNESDAY NIGHT AND INCREASED DEFORMATION IN THE
850-700 LAYER ACROSS OUR NORTH COUNTIES.  WITH THETA-E RIDGE AXIS IN
PLACE AND SURFACE-500MB MEAN RH FIELDS IN EXCESS OF 80% WITH WARM
CLOUD DEPTHS 12K-13K FEET...PRECIP EFFICIENCY LOOKS GOOD.  PERHAPS
THE ONLY MAIN INGREDIENT MISSING IS A STRONGER LOW LEVEL JET AS
PROGS ONLY SUPPORT 20KTS AT 850MB.  WHILE WE WILL NOT HOIST ANY
HEADLINES AT THIS TIME...WE WILL CONTINUE TO HIGHLIGHT WITHIN THE
HWO AND DAY CREW WILL HAVE ANOTHER LOOK WITH THE 12Z MODEL GUIDANCE.

THIS FRONT AND UPPER LEVEL SUPPORT SLOWLY MIGRATE SOUTHEAST THURSDAY
WHERE WE WILL CONTINUE WITH THE THREAT FOR ADDITIONAL SHOWERS.  BOTH
THE NAM AND GFS INCREASE FRONTOGENESIS AS THERMAL PACKING DOES
INCREASE SOMEWHAT.  BUT INSTABILITY IS NOT AS STRONG OF A SIGNAL
WITH SWI/S CLIMBING ABOVE 0C THROUGH THE DAY HENCE THE REMOVAL OF
THUNDER FROM THE FORECAST.

CONFIDENCE IN ANY MODEL SOLUTION...WHILE NATURALLY DECREASES THE
FURTHER OUT WE GO...DECREASES EVEN FURTHER WITH QUITE A BIT OF
CONVECTIVE ELEMENTS AND AFTER-EFFECTS IN THE MODEL SCALE RESULTING
IN DIFFICULT TIMING AND STRENGTH OF WAVES TO IMPACT THE REGION
FRIDAY AND LATER IN THE WEEKEND.  BASED ON PRELIMINARY HPC GUIDANCE
AND DPROG/DT OF THE GFS...RIDGES SETTLES INTO THE REGION FOR THE
FIRST HALF OF THE WEEKEND TO BE FOLLOWED BY ANOTHER PACIFIC WAVE AND
WARM ADVECTIVE PROCESSES SUNDAY-MONDAY TIMEFRAME.  TEMPERATURES AND
DEWPOINTS SHOULD DROP BACK TO SEASONABLE LEVELS FOR MOST OF THIS
FIRST WEEKEND OF JUNE.
