What was reported inside it

Time	Report	Where	Remark
Jun 22, 5:38 PM EDT	HAIL 0.75	Onaway State Park, MI

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Alpena, MI (KAPX), launched 12:00Z, 9.3 hours before the alert went out and 136 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Skew-T log-p

Temperature in red, dew point in green, the mixed-layer parcel dashed.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Gaylord, MI wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 22, 4:05 PM EDT, 1 hour 14 minutes earlier.

Area forecast discussion, Jun 22, 4:05 PM EDT, 1 hour 14 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GAYLORD MI
405 PM EDT SUN JUN 22 2008

.DISCUSSION...AFTERNOON SYNOPSIS...LIKE YESTERDAY...CONVECTION
BLOSSOMING WITH AFTERNOON HEATING ACROSS A GOOD CHUNK OF NORTHERN
LOWER MICHIGAN...WITH SPOTTIER DEVELOPMENT ACROSS CHIPPEWA COUNTY
LIKELY TIED TO THE LAKE BREEZE.  BIT OF EXCITEMENT THIS AFTERNOON
WITH A COUPLE SUPERCELLS DEVELOPING OVER NORTHEAST LOWER...PROBABLY
HOOKED UP WITH THE LAKE HURON BREEZE OR SOME OTHER BOUNDARY TO SET
THEM SPINNING...WITH A TORNADO TOUCHDOWN NEAR HUBBARD LAKE IN ALCONA
COUNTY.  OTHERWISE SMALL HAILERS HAVE BEEN THE MAIN FOCUS WITH
MLCAPE VALUES FROM 800-1200 J/KG.

SHORT WAVE TROUGH AXIS WILL HANG OVER THE STATE TONIGHT...WITH A
GENERALLY WEAK PRESSURE PATTERN IN PLACE.  FOR THE MOST PART
PRECIPITATION SHOULD BE TIED TO THE DIURNAL HEATING CYCLE LIKE THE
PAST COUPLE OF DAYS...SO ANTICIPATE THINGS WILL WIND DOWN AS THE
EVENING PROGRESSES BUT CANT RULE OUT SOME ISOLATED CONVECTION
THROUGH THE NIGHT WITH THE UPPER TROUGH IN PLACE.  DEPENDING ON HOW
THE CLOUD COVER SHAKES OUT SOME FOG/ST MAY DEVELOP OVERNIGHT
ESPECIALLY IN AREAS THAT PICKED UP RAIN THIS AFTERNOON.

JPB

MONDAY AND MONDAY NIGHT...SLOW MOVING MID LEVEL TROUGH ACROSS THE
GREAT LAKES WILL CONTINUE TO BE THE DOMINATE PLAYER FOR ONE MORE DAY
BEFORE FINALLY PUSHING EAST OF THE STATE MONDAY NIGHT. AND ONE MORE
DAY OF SHOWER/THUNDERSTORM CHANCES TO CONSIDER TIED PRIMARILY TO THE
DIURNAL HEATING CYCLE. MAIN FORECAST ISSUE IS PLACEMENT/TIMING OF
THE BEST CHANCES. BY MONDAY MORNING...LOW-MID LEVEL TROUGH AXIS
EXPECTED TO BISECT NORTHEAST LOWER MICHIGAN WITH THE MID LEVEL
VORTICITY MAX IN SRN LOWER MICHIGAN. PRIMARY QG-UPWARD SUPPORT WILL
BE LOCATED WELL OFF TO THE SOUTH/EAST OF THE CWA (AHEAD OF THE MID
LEVEL WAVE). HOWEVER...MAY STILL BE ABLE TO SQUEEZE OUT SOME SHOWER
ACTIVITY ALONG AND AHEAD OF THE LOW-MID LEVEL TROUGH AXIS DURING THE
MORNING HOURS...AND PLAN TO HAVE LOW CHANCY POPS ACCORDINGLY.
SECONDARY MID LEVEL TROUGH AXIS ALSO DEPICTED ALONG THE NW SIDE OF
THE TROUGH SLIPPING DOWN ACROSS EASTERN UPPER/NW LOWER MICHIGAN. BUT
OUTSIDE OF SOME ENHANCED BAND OF CLOUD COVER DON/T FEEL THERE WILL
BE ENOUGH THERE TO WARRANT RAIN CHANCES.

THEN...TROUGH AXIS SLIPS EAST OF THE AREA BY AFTERNOON. HOWEVER...
WITH SFC DEWPOINTS STILL LINGERING IN THE LOWER 50S AND COOLER AIR
REMAINING ALOFT...WILL HAVE YET ANOTHER OPPORTUNITY TO BUILD DAYTIME
INSTABILITY ESPECIALLY ACROSS THE SE COUNTIES (AROUND 300 J/KG
MLCAPE PER MODIFIED FORECAST SOUNDINGS) WHERE SLIGHTLY HIGHER
DEWPOINTS AND TEMPERATURES ARE EXPECTED. NO SYNOPTIC TRIGGER TO
SPEAK OF. BUT WITH RELATIVELY LIGHT WINDS...LAKE BREEZES SHOULD HAVE
NO PROBLEM DEVELOPING ALONG THE LAKE HURON SHORE RESULTING IN LOW
LEVEL CONVERGENCE OVER NORTHEAST LOWER MICHIGAN. WITH THIS IN
MIND...WILL CARRY CHANCE-SCT SHOWERS/STORMS FOR THIS AREA DURING THE
AFTERNOON...HIGHEST NEAR THE SAGINAW VALLEY. AND ONCE AGAIN WITH
FREEZING LEVELS UNDER 10K FEET AND LIGHT WINDS...ANY STORM MAY
PRODUCE HAIL.

TUESDAY THROUGH THURSDAY...A TRANSITION TO A MORE ZONAL OR LOW
AMPLITUDE RIDGING PATTERN SHAPING UP...ACROSS THE PLAINS AND RUNNING
THROUGH THE GREAT LAKES. TEMPERATURES AT OR EVEN A LITTLE ABOVE
NORMAL...PARTICULARLY TOWARD THE END OF THE WORK WEEK. BUT IN
TYPICAL SUMMERTIME FASHION CERTAINLY A DIFFICULT PATTERN TO PICK OUT
PERIODS IN THE EXTENDED WITH BETTER CHANCES FOR SHOWERS. LATEST
RENDITIONS OF THE GFS/ECMWF SHOWING LOOSE AGREEMENT WITH ONE MID
LEVEL IMPULSE PASSING THROUGH THE WESTERN GREAT LAKES LATE TUESDAY
NIGHT THROUGH WEDNESDAY...ALONG WITH A PUSH OF WARMER/HIGHER
DEWPOINT AIR INTO THE REGION. SO CURRENT FORECAST FOR CHANCE
SHOWERS/STORMS DURING THAT TIME LOOKS FINE FOR NOW. SOME OF THIS
ACTIVITY MAY LINGER INTO WEDNESDAY EVENING...BUT WILL NOT GET CUTE
WITH TIMING THIS FAR OUT...AND LEAVE GOING SHOWER CHANCES IN THROUGH
THE 12 HOUR PERIOD.

FRIDAY THROUGH SUNDAY...STRONGER WAVE SLATED TO MOVE THROUGH SOUTH
CENTRAL CANADA FRIDAY AND DEEPEN OVER THE GREAT LAKES/EASTERN CANADA
DURING THE WEEKEND...A PATTERN WE/VE SEEN OVER THE LAST SEVERAL
MONTHS. SO...SHOWER AND THUNDERSTORM CHANCES LOOKING TO RETURN LATER
FRIDAY AND FRIDAY NIGHT AS THE MAIN DYNAMICS WITH THIS SYSTEM
PRESSES THROUGH THE AREA. BUT UNCLEAR AT THIS POINT JUST HOW LONG
THIS NEXT SYSTEM WILL BE WITH US AS THE ECMWF IS TRENDING DEEPER AND
SLOWER. BUT FEELING IS CURRENT DRY WEEKEND FORECAST MAY BE IN
JEOPARDY...ESPECIALLY SATURDAY WITH THE CLOSED LOW STILL MOVING
THROUGH ONTARIO/QUEBEC AND NRN MICHIGAN POTENTIALLY SITTING WITHIN
DEEP CYCLONIC FLOW REGIME. BUT UPON COLLABORATION WITH SURROUNDING
OFFICES WILL HANG ON TO A DRY FORECAST FOR NOW...AND SEE WHERE THIS
GOES OVER THE NEXT FEW DAYS.
