Flash Flooding and Hail in Michigan, June 25, 2009
A weak low pressure system coupled with high instability triggered several severe thunderstorms along and south of I-69 during the afternoon hours of June 25th, into the early evening hours. Southern Macomb county was hardest hit, as the majority of the 80,000 DTE customers who lost power resided in Macomb county.

Area forecast discussion, Jun 25, 12:38 PM EST, 12 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 138 PM EDT THU JUN 25 2009 .AVIATION... VERY UNSTABLE ATMOSPHERE IN PLACE ACROSS ALL TAF SITES THIS AFTERNOON SOUTH OF A COLD FRONT LOCATED ACROSS MID MICHIGAN. CU FIELD HAS BEGUN TO DEVELOP AS SHOWN ON VISIBLE SATELLITE AND SHOULD INCREASE IN COVERAGE WITH THE ABUNDANT LOW LEVEL MOISTURE IN PLACE. STRONG INSTABILITY IN COMBINATION WITH GOOD UPPER LEVEL SUPPORT WILL PROVIDE A VERY GOOD CHANCE FOR THUNDERSTORMS TO IMPACT TAF SITES EARLY THIS EVENING. MOST OF THE ACTIVITY SHOULD EXIT THE SITES BY ABOUT 10 PM. WILL MONITOR STORM DEVELOPMENT AND AMEND TAFS AS NECESSARY FOR TIMING. OVERNIGHT...SKIES SHOULD CLEAR AS WINDS BECOME NORTHERLY BEHIND THE PASSING COLD FRONT. && .PREV DISCUSSION...ISSUED 358 AM EDT THU JUN 25 2009 SHORT TERM...TODAY A WEAK ILL-DEFINED SURFACE BOUNDARY IS SHOWN EXTENDING ACROSS CENTRAL MICHIGAN ON THE 07Z SURFACE ANALYSIS. THIS FRONT WILL PROVIDE A FOCUS FOR THUNDERSTORM DEVELOPMENT TODAY AS IT SLIDES SOUTH INTO THE HUMID AND UNSTABLE AIRMASS ACROSS SOUTHERN MICHIGAN. SOME CONVECTION IS STILL POSSIBLE ACROSS THE SAGINAW VALLEY AND THUMB LATER THIS MORNING ALONG THE FRONTAL BOUNDARY AS WEAK SHORT ENERGY NOTED UPSTREAM OVER WISCONSIN PASSES ACROSS LOWER MICHIGAN. MORE NUMEROUS CONVECTION IS EXPECTED DURING THE AFTERNOON AS THE MID LEVEL WAVE NOW OVER THE MANITOBA/ONTARIO BORDER SLIDES ACROSS THE NORTHERN GREAT LAKES AND AMPLIFIES...ALLOWING MID LEVEL HEIGHTS TO DROP ACROSS SOUTHERN MICHIGAN. ADDITIONAL UPSTREAM SHORT WAVE ENERGY AND CONVERGENCE ALONG THE SURFACE FRONT AND/OR OTHER SURFACE BOUNDARIES WILL HELP FOCUS CONVECTIVE DEVELOPMENT THIS AFTERNOON. THE UPPER FLOW WILL ALSO BECOME INCREASINGLY DIFFLUENT DURING THE COURSE OF THE DAY...AND EXIT REGION JET DYNAMICS WILL INCREASE AS THE UPPER JET MAX OBSERVED OVER SOUTHERN SASKATCHEWAN ON THE 00Z UPPER AIR PLOTS DIVES INTO THE WESTERN GREAT LAKES. UPSTREAM 00Z SOUNDINGS REVEALED A DEEP ELEVATED MIXED LAYER...WHICH WILL ADVECT ACROSS THE FORECAST AREA TODAY AND COMBINE WITH DAYTIME HEATING AND MOISTURE POOLING ALONG THE SURFACE FRONT TO CREATE AMPLE INSTABILITY. MODEL SOUNDINGS INDICATE 0-1KM MIXED LAYER CAPE APPROACHING 2000 J/KG. A 40-45KT 500MB WIND MAX IS EXPECTED TO PROGRESS INTO THE STATE DURING THE AFTERNOON...ACCOMPANIED BY A SURGE OF MID LEVEL DRY AIR. THESE FACTORS WILL FAVOR LINEAR CONVECTIVE MODES WITH THE THREAT FOR DAMAGING WIND GUSTS. GIVEN THE POTENTIAL FOR PREFRONTAL TROUGHING/LAKE BREEZE BOUNDARIES/CONVECTIVE OUTFLOW...STORM RELATIVE HELICITY MAY FAVOR SOME SUPERCELLS EARLY IN THE CONVECTIVE EVENT. ALL THESE FACTORS HAVE LED TO SPC PLACING ALL OF SOUTHEAST MICHIGAN IN A SLIGHT RISK FOR SEVERE WEATHER ON THE DAY ONE OUTLOOK. SURFACE DEWPOINTS ARE EXPECTED TO BE IN THE UPPER 60S/LOWER 70S ALONG AN AHEAD OF THE SURFACE FRONT. WHILE THERE WILL BE SOME MID AND HIGH LEVEL CLOUDS AROUND THIS MORNING...ENOUGH HEATING IS EXPECTED TO CREATE ANOTHER HOT AND HUMID DAY. IN ANTICIPATING A LATER START TO CONVECTION ALONG AND SOUTH OF I-94...MAX TEMPS NEAR 90 LOOK REASONABLE. MEANWHILE...IN ANTICIPATING EARLY TO MID AFTERNOON CONVECTION...WILL KEEP FORECAST HIGHS IN THE 80S NORTH OF THE I-94 CORRIDOR. LONG TERM...TONIGHT THROUGH WEDNESDAY UPPER TROUGH WILL EXIT EAST OUT OF MICHIGAN EARLY TONIGHT AS UPPER RIDGING BUILDS TO OUR WEST. THIS WILL ALLOW LOWER MICHIGAN TO FALL UNDER THE INFLUENCE OF SURFACE HIGH PRESSURE...AND BRING AN END TO ANY LINGERING SHOWERS AND THUNDERSTORMS DURING THE LATE EVENING. SURFACE HIGH PRESSURE WILL THEN HOLD INTO SATURDAY AS THE UPPER RIDGE AXIS SLOWLY TRANSLATES EAST ACROSS THE GREAT LAKES. SOME QUESTION AS TO HOW MUCH INSTABILITY WILL BE PRESENT ON FRIDAY AS LAKE BREEZES MOVE INLAND. GFS MODEL SOUNDINGS FROM 00Z INDICATE ENOUGH WARMING ALOFT FROM THE RIDGE TO INHIBIT THUNDERSTORM FORMATION...HOWEVER THE NAM IS A BIT STEEPER WITH THE MID LEVEL LAPSE RATES AND ALLOWS A DEEPER LAYER OF INSTABILITY TO DEVELOP. WILL CONTINUE TO FOLLOW THE MORE STABLE GFS AS UPPER RIDGING BUILDS IN AND WATCH FOR ANY WESTWARD SHIFT WITH THE RIDGE AXIS WHICH COULD PREVENT SOME OF THE WARMING ALOFT SHOWN ON THE GFS SOUNDINGS. STRONG UPPER LOW OVER BRITISH COLUMBIA WILL TRACK ACROSS CANADA AND INTO THE WESTERN GREAT LAKES ON SATURDAY/SATURDAY NIGHT. THIS WILL PUSH A STRONG SURFACE LOW ACROSS THE NORTHERN GREAT LAKES SATURDAY NIGHT...THOUGH MODELS CONTINUE TO DIFFER ON WHETHER THE CENTER OF THIS SYSTEM WILL PUSH ACROSS CENTRAL ONTARIO OR NORTHERN MICHIGAN...LEADING TO SOME DIFFERENCES WITH WHERE THEY PLACE THE FRONTAL BOUNDARIES/OCCLUSION AND INSTABILITY. RECENT SHIFT TO NOCTURNAL TIMING OF FRONTAL/OCCLUSION PASSAGE WOULD BODE FAVORABLE FOR SOUTHEAST MICHIGAN AS THIS WOULD KEEP THE HIGHEST SURFACE/MIXED LAYER INSTABILITY WELL TO OUR WEST OVER WISCONSIN SATURDAY AFTERNOON/EVENING. DID LEAVE SOME POPS IN FOR LATE SATURDAY AFTERNOON...BUT THIS WAS MORE TO COVER UNCERTAINTY IN TIMING RATHER THAN INSTABILITY AND LIFT AHEAD OF THE SYSTEM. 00Z GFS/NAM SOUNDINGS ARE ACTUALLY QUITE STABLE NOW FOR SATURDAY AFTERNOON...ESPECIALLY IN THE MID LEVELS. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL BECOME LIKELY OVERNIGHT ON SATURDAY AS THE SYSTEM MOVES ACROSS...WITH SOME ACTIVITY LINGERING INTO THE FIRST HALF OF THE DAY ON SUNDAY. WILL HAVE TO KEEP AN EYE ON MODEL TIMING HOWEVER...AS WE HAVE SEEN A TENDENCY TO SLOW THINGS DOWN OVER THE PAST FEW DAYS. MEDIUM RANGE MODELS ARE IN FAIRLY GOOD AGREEMENT WITH THE CANADIAN UPPER LOW STALLING OVER THE GREAT LAKES SUNDAY THROUGH WEDNESDAY. WHILE ANY SHORTWAVES AND FRONTS WILL BE HARD TO TIME...SUFFICIENT MOISTURE AND GOOD INSTABILITY GENERATED FROM THE UPPER COLD POOL SUPPORTS A BROAD-BRUSH CHANCE OF SHOWERS ALONG WITH DAYTIME THUNDERSTORMS THROUGH THE PERIOD. HAVE ALSO COOLED THE FORECAST SLIGHTLY AS WE SHOULD EXPECT BELOW NORMAL TEMPERATURES UNDER THE UPPER LOW. MARINE... A WEAK COLD FRONT AND UPPER LEVEL DISTURBANCE WILL TRIGGER SEVERAL ROUNDS OF THUNDERSTORMS TODAY. SOME OF THESE STORMS WILL BE STRONG TO SEVERE WITH THE POTENTIAL FOR WIND GUSTS GREATER THAN 40 KNOTS. WEAK HIGH PRESSURE WILL EXPAND ACROSS THE AREA ON FRIDAY AND LINGER INTO SATURDAY...PROVIDING LIGHT WINDS AND IDEAL BOATING CONDITIONS. A STRONG COLD FRONT IS FORECAST TO MOVE THROUGH THE REGION EARLY SUNDAY. THIS SYSTEM WILL TRIGGER THUNDERSTORMS. COLD AIR ADVECTION BEHIND THIS FRONT MAY BE STRONG ENOUGH TO CREATE SOME GUSTY WINDS AND HIGHER WAVES SUNDAY INTO EARLY MONDAY. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE.
