The episode as NWS APX wrote it up.
A cluster of strong to severe thunderstorms moved off of Lake Michigan into Northwest Lower Michigan.
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 Gaylord, MI wrote its last area forecast discussion before the first event at Jun 23, 8:09 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GAYLORD MI 909 PM EDT WED JUN 23 2010 .SYNOPSIS.../ISSUED AT 334 PM/ SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS NORTHERN MICHIGAN IN ADVANCE OF AN APPROACHING COLD FRONT. THE FRONTAL BOUNDARY WILL PASS THROUGH LATER TONIGHT...TAKING THE PRECIPITATION WITH IT...AND ALLOWING MUCH DRIER AIR TO FILTER INTO THE AREA FOR THE REMAINDER OF THE WORK WEEK. BERGER && .SHORT TERM.../ISSUED AT 909 PM/...TONIGHT LARGE STRONG/SVR TSTORM MOVING OFF OF DOOR CO WI. OUR AIRMASS...AS ILLUSTRATED BY THE 00Z APX SOUNDING...IS CONSIDERABLY LESS UNSTABLE THAN UPSTREAM. EVEN ADJUSTING FOR SOMEWHAT RICHER SURFACE PARCELS TO THE SW...75/65 ONLY GIVES US A FEW HUNDRED J/KG OF VERY SKINNY MLCAPE TO PLAY WITH (AND EVEN THAT WILL ONLY DECREASE WITH TIME). THAT SAID...THE UPSTREAM STORM IS WELL-ORGANIZED...AND MAY BE IN POSITION TO TAKE BETTER ADVANTAGE OF OUR MEAGER INSTABILITY THAN A GARDEN-VARIETY CELL. THAT ALSO SAID...IT APPEARS THAT SOME WEAKENING IS ALREADY OCCURRING. REGARDLESS...IT SEEMS READILY APPARENT THAT PARTS OF NW LOWER MI WILL GET WET...AND POPS HAVE BEEN INCREASED IN THE GD TRAVERSE BAY REGION. EXPECT ONE (OR MORE) ADDITIONAL UPDATES THIS EVENING...AS WE GET A BETTER LOOK AT HOW THE LAKE WILL TREAT UPSTREAM CONVECTION. FOR NOW...SVR WX APPEARS DOUBTFUL BUT NOT IMPOSSIBLE. JZ && .LONG TERM.../ISSUED AT 334 PM/...THURSDAY AND BEYOND WATER VAPOR IMAGERY EARLY THIS AFTERNOON REVEALS A PRETTY POTENT WESTERLY FLOW STRETCHING FROM THE CENTRAL PACIFIC EAST THROUGH CENTRAL NOAM...COURTESY OF HEIGHTS SLIGHTLY ABOVE NORMAL OVER THE SUBTROPICS ALONG WITH MULTIPLE LOW CENTERS ALONG ABOUT 50N. THE UPPER LOW CENTERED OVER WESTERN HUDSON BAY EARLY THIS AFTERNOON WILL STRENGTHEN WITH TIME IN RESPONSE TO DOWNSTREAM BLOCKING OVER GREENLAND...WHICH WILL MAINTAIN WEST NORTHWEST FLOW ALOFT OVER OUR AREA WITH THE PRIMARY POLAR FRONT NEAR OUR GENERAL VICINITY THROUGH THE UPCOMING WEEKEND. THERE ARE SIGNS...HOWEVER...THAT TOWARDS EARLY NEXT WEEK THE AFOREMENTIONED BLOCKING TOWARDS GREENLAND WILL STRENGTHEN AND CAUSE THE UPSTREAM FLOW TO SLOW...AND BUCKLE WITH STRENGTHENING CENTRAL NOAM RIDGING ALONG WITH TROUGHING ALONG EACH COAST. NEARLY ALL DETERMINISTIC/ENSEMBLE GUIDANCE IS ON BOARD WITH THIS IDEA WHICH WOULD BRING A DRYING/COOLING TREND TO THE AREA BY EARLY NEXT WEEK. PERIOD STARTS WITH DEPARTING MID LEVEL SHORTWAVE AND COOLER/DRIER AIR FILTERING INTO THE REGION FROM THE NORTH AND WEST AS SURFACE HIGH PRESSURE BUILDS RAPIDLY OVERHEAD DURING THE DAY. AS WE HAVE SEEN OVER THE PAST FEW EVENTS...EXPECT SOME STRATUS TO BE STUCK UNDER THE DEVELOPING SUBSIDENCE INVERSION...AND THE EVOLUTION OF ANY STRATUS WILL BE THE BIGGEST QUESTION IN THE THURSDAY FORECAST. WILL INCREASE CLOUD COVER SUBSTANTIALLY THROUGH THE MORNING...WITH CLEARING BY AFTERNOON. THIS WILL HAVE AN IMPACT ON TEMPS...WITH HIGHS OCCURRING LATE IN THE DAY WITH A SLOW INITIAL DIURNAL RISE. T85S WILL SUPPORT MID/UPPER 70S...BUT GIVEN THE SLOWER RISE AND LIMITED VERTICAL MIXING DUE TO SUBSIDENCE ALOFT...WILL LOWER HIGHS TO THE LOWER 70S OVER EASTERN UPPER AND EXTREME NORTHERN LOWER...INCREASING TO THE UPPER 70S FROM GRAYLING SOUTH AND EAST WHERE THERE WILL BE THE MOST SUN THROUGH THE DAY. CONTINUED CLEARING ALONG WITH MORE SIGNIFICANT LEVEL DRYING SPELLS A COOL NIGHT THURSDAY NIGHT AND HAVE LITTLE REASON TO DEPART FROM GOING LOWS WHICH ARE AT OR BELOW GUIDANCE. THIS YIELDS LOWS IN THE LOWER TO MIDDLE 40S. WOULDN/T BE SURPRISED TO SEE ONE OR TWO LOCATIONS DROP JUST BELOW 40 IF WE REMAIN FULLY CLEAR THROUGH THE NIGHT GIVEN NEARLY OVERHEAD SURFACE HIGH PRESSURE. HIGH PRESSURE SETTLES EAST OF THE AREA ON FRIDAY WITH RETURN FLOW DEVELOPING. DEEP MOISTURE REMAINS SOUTH AND WEST OF THE AREA THROUGH THE DAY...HOWEVER...WITH ONLY MODEST WARM AIR ADVECTION. THE RESULT SHOULD BE A P/MSUNNY DAY WITH SOME HIGH CLOUDINESS SPILLING EAST FROM CONVECTION LIKELY TO DEVELOP OVER THE NORTHERN MIDWEST DUE TO A SMALL SCALE NORTHERN STREAM DISTURBANCE. T85S WARM A DEGREE OR TWO AND WITH MORE SUNSHINE EXPECT HIGHS IN THE MIDDLE TO UPPER 70S FROM NORTH TO SOUTH WITH COOLER TEMPS ALONG THE LAKESHORES...PARTICULARLY ALONG LAKE MICHIGAN. A SERIES OF DISTURBANCES IN THE WEST-NORTHWEST FLOW ALOFT LOOK TO IMPACT THE AREA THROUGH THE UPCOMING WEEKEND. WHILE I HAVE LITTLE TO NO CONFIDENCE ON THE DETAILS OF THESE FEATURES...I THINK IT WILL BE A MORE UNSETTLED PERIOD AS THESE FEATURES INTERACT WITH A NEARBY FRONTAL ZONE. THIS SETUP COULD FAVOR ONE TO TWO MCS/S IMPACTING THE REGION...SO WE/LL HAVE TO KEEP AN EYE ON THIS PERIOD FOR HEAVY RAIN/SVR POTENTIAL. WILL CERTAINLY KEEP POPS IN THE CHANCE CATEGORY AS CONFIDENCE IN PLACEMENT/TIMING IN DOUBT. DROPPED TEMPS JUST SLIGHTLY DURING THIS PERIOD GIVEN POTENTIAL CONVECTIVE CONTAMINATION...WITH HIGHS LOWER THAN THOSE IMPLIED BY THE TEMPS AT H85. AS WE MOVE INTO THE FIRST HALF OF NEXT WEEK...THE FLOW AMPLIFICATION MENTIONED ABOVE SHOULD FINALLY BE ABLE TO DRIVE THE NEARBY BAROCLINIC ZONE SOUTH...WITH DRIER AIR FILTERING INTO THE REGION. WILL MAINTAIN GOING DRY FORECAST THROUGH THE END OF THE PERIOD AND SLOWLY BEGIN TO LOWER TEMPERATURES. IT/S LOOKING MORE AND MORE LIKE AN ANOMALOUSLY COOL PERIOD GIVEN T85S DROPPING BELOW 10C WITH THE ECMWF SUGGESTING T85S MAY MAKE A RUN AT 0C!! WILL DROP HIGHS...PARTICULARLY ON TUESDAY/WEDNESDAY /DOWN ABOUT A CATEGORY/ INTO THE LOWER/MIDDLE 70S...BUT THESE MAY STILL BE TOO OPTIMISTIC IF GOING TRENDS IN THE GUIDANCE CONTINUE. IN ANY CASE...TEMPERATURES BELOW SEASONAL NORMS ARE LOOKING INCREASINGLY LIKELY...AS WELL AS DRY CONDITIONS. ARNOTT && .MARINE.../ISSUED AT 334 PM/ SOUTHWEST WINDS WILL SHIFT NORTHWEST THIS EVENING AS A COLD FRONT PUSHES THROUGH THE GREAT LAKES REGION. BEFORE THE COLD FRONT MOVES THROUGH THIS EVENING...SHOWERS AND EMBEDDED THUNDERSTORMS ARE POSSIBLE. NORTHWEST WINDS WILL FRESHEN BEHIND THE DEPARTING COLD FRONT DURING THE DAY THURSDAY WITH CLEARING SKIES. CONDITIONS WILL APPROACH THOSE HAZARDOUS TO SMALL CRAFT DURING THE DAY THURSDAY. HIGH PRESSURE SETTLES OVERHEAD THURSDAY NIGHT WITH MOSTLY CLEAR SKIES AND WINDS BECOMING LIGHT. ARNOTT && .AVIATION.../ISSUED AT 728 PM/...VALID FOR 00Z TAFS WAVY COLD FRONT PRESSING EASTWARD ACROSS WI. STRONG TSRA HAVE RECENTLY DEVELOPED IN NORTHERN WI...W AND N OF GRB. HOWEVER... AIRMASS OVER NORTHERN MI IS ONLY MARGINALLY UNSTABLE (AT BEST) GIVEN LIMITED SUNSHINE TODAY. THUS...UPSTREAM STORMS WILL WEAKEN...WITH A BAND OF SHOWERS (AND MAYBE A RUMBLE OF THUNDER) FOR THE TAF SITES LATE EVENING AND EARLY OVERNIGHT. COOLER AND DRIER AIR WILL ENTER THE REGION ON FRIDAY...THOUGH APN COULD SEE MVFR CONDITIONS FOR A FEW HOURS IN THE MORNING. JZ && .APX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LM...NONE. LH...NONE. LS...NONE. &&
