Steep low level lapse rates and dry low levels ahead of a cold front, allowed for the development some a few thunderstorms across central Lower Michigan, which dropped southeast. A few of these storms clipped portions of Branch and St Joseph counties with isolated damaging wind gusts.

The episode as NWS IWX wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
814 PM EDT MON JUN 17 2013
.SYNOPSIS...
ISSUED AT 425 PM EDT MON JUN 17 2013
A WEAK COLD FRONT WILL APPROACH THE REGION THIS EVENING AND BRING
A CHANCE FOR SHOWERS AND THUNDERSTORMS OVERNIGHT AND AGAIN TUESDAY
EVENING. HIGH PRESSURE WILL THEN BUILD OVER THE GREAT LAKES BY
MIDWEEK WITH A RETURN TO DRY CONDITIONS.
&&
.UPDATE...
ISSUED AT 812 PM EDT MON JUN 17 2013
UPDATED MAINLY TO FRESHEN ZFP WORDING... BUT ALSO BUMPED UP POPS A
BIT NWRN AREAS THIS EVE DUE TO SCT SHOWERS OVER AND APCHG THIS
AREA. AS MENTIONED IN AVIATION DISCUSSION... INSTABILITY CURRENTLY
LIMITED OVER OUR CWA AND PROSPECT FOR DESTABILIZATION SLIM WITH
MCS OVER THE LWR OH VALLEY PREVENTING MUCH THETA-E ADVECTION AHEAD
OF THE FRONT... SO TSTM COVERAGE ONLY EXPECTED TO BE ISOLATED TO SCATTERED
IN OUR AREA. STEEP LOW LEVEL LAPSE RATES AND FAIRLY DRY LOW LEVELS
WILL SUPPORT GUSTY WINDS AND PSBLY SMALL HAIL IF THUNDERSTORMS DO
OCCUR THROUGH THE EVE BEFORE DIURNAL COOLING STABILIZES LOW
LEVELS.
&&
.SHORT TERM...(THIS EVENING THROUGH TUESDAY)
ISSUED AT 350 PM EDT MON JUN 17 2013
PERTURBED WNW FLOW ALOFT WILL PERSIST THIS PERIOD BETWEEN AN EASTERN
CANADA NEGATIVE HEIGHT ANOMALY AND AN INTERMOUNTAIN WEST/SOUTHERN
PLAINS UPPER RIDGE. A SHEARED PV FILAMENT EMBEDDED IN THIS FLOW
OVER WISCONSIN WILL TRANSLATE THROUGH THE CENTRAL GREAT LAKES THIS
EVENING...FORCING A BACKDOOR COLD FRONT SOUTHEAST THROUGH THE AREA
TONIGHT. THIS COLD FRONT WILL GET A LITTLE EXTRA BOOST FROM COOL
LAKE MICHIGAN WATERS...FORCING IT INTO FAR NW ZONES BY 00Z. ISOLATED
TO SCATTERED CONVECTION MAY FIRE BTW 23-02Z ALONG THIS BOUNDARY AND
THEN SLOWLY WORK SOUTHEASTWARD OVERNIGHT. KEPT COVERAGE/PROBABILITY
OF CONVECTION LOW (20-30 PERCENT) WITH DEEPER MOISTURE LOCKED UP
SOUTH OF THE AREA AND STRONGER SUPPORT ALOFT PASSING NORTH AND EAST
OF THE IWX CWA. MODERATE DEEP LAYER SHEAR (40-45 KNOTS) AND WEAK
INSTABILITY (500-1000 J/KG OF MLCAPE) MAY SUPPORT AN ISOLATED
WIND/HAIL THREAT IF CONVECTION FIRES EARLY THIS EVENING ACROSS
NORTHERN ZONES.
FRONTAL SLOPE WILL SINK JUST SOUTH OF THE HWY 24 CORRIDOR BY 12Z
TUESDAY...AND THEN CLEARING OUR SOUTHEASTERN ZONES BY MIDDAY. LOW
LEVEL COOL/DRY ADVECTION WILL BE MORE IMPRESSIVE OVER THE NORTHERN HALF
OF THE FA...ESPECIALLY DOWNWIND OF LAKE MICHIGAN INTO NW INDIANA AND
SW LOWER MICHIGAN...WITH GUIDANCE BACKING OFF SOMEWHAT ON THIS
COOL/DRY PUSH INTO SOUTHERN AREAS. 12Z GUIDANCE ALSO CAME IN A LITTLE
STRONGER WITH A MORE PRONOUNCED PV ANOMALY (ACROSS THE NORTHERN
PLAINS AS OF THIS WRITING) PROGGED TO DROP SOUTHEAST THROUGH THE
NORTHERN OHIO VALLEY TUESDAY AFTERNOON. THIS UPPER LEVEL SUPPORT PER
DCVA/7-3H Q VECTOR CONVERGENCE PROGS...COUPLED WITH MODEST BL
DESTABILIZATION (MAYBE 1000-1500 J/KG OF CAPE TO WORK WITH) AND A
POSSIBLE LOW LEVEL FOCUS ALONG A LEFTOVER INVERTED-LIKE TROUGH MAY
COMBINE TO HELP GENERATE SCATTERED SHOWERS/STORMS TUESDAY
AFTERNOON...BEST CHANCES SOUTH OF HWY 30 IN INDIANA. BUMPED UP POPS
A BIT BUT HELD SHY OF LIKELY WITH DEEPER MOISTURE AND MORE UNSTABLE
AIR SUPPRESSED SOUTH OF THE AREA ALONG THE PRIMARY BAROCLINIC
ZONE. THERE DOES APPEAR TO BE A MARGINAL HAIL/WIND THREAT WITH
SUSTAINABLE UPDRAFTS GIVEN PROGGED WEAK TO MODERATE INSTABILITY AND
NEAR 40 KNOTS OF EFFECTIVE DEEP SHEAR.
&&
.LONG TERM...(TUESDAY NIGHT THROUGH MONDAY)
ISSUED AT 350 PM EDT MON JUN 17 2013
A WEAK UPPER LEVEL TROF WILL BE MOVING ACROSS THE SOUTHERN PART OF
THE AREA EARLY IN THE PERIOD. NCEP MODELS HAVE BEEN TRENDING UP THE
CHANCES OF PRECIPITATION OVER SOUTHEAST AREAS AS THE UPPER LEVEL
TROF COMBINES WITH A WEAK FRONT AND MOVES SOUTHEAST. ADDED A CHANCE
FOR SHOWERS AND THUNDER BEFORE MIDNIGHT TUESDAY NIGHT. BULK SHEAR
AND CAPE SHOULD NOT BE SUFFICIENT FOR SEVERE STORMS. THIS SYSTEM
SHOULD MOVE OUT OF THE AREA FAIRLY QUICKLY...WITH DRY WEATHER AND
MODERATING TEMPERATURES THROUGH THE END OF THE WORK WEEK AS AN UPPER
LEVEL RIDGE BUILDS INTO THE AREA. HAVE TRENDED TEMPERATURES WARMER
OVER THE LAST SEVERAL DAYS OF THE THIS PERIOD. CR ALLBLEND LOOKS TOO
COOL AND APPEARS TO HAVE INGESTED SOME OF THE COOLER MODEL DATA.
OVERALL...FAVOR THE GFS WITH AN UPPER RIDGE EXTENDING INTO THE
FORECAST AREA OVER THE WEEKEND. 850 MB TEMPERATURES OVER 20C SUPPORT
HIGHS AROUND OR TOPPING 90 DEGREES. CR ALLBLEND HAS TRENDED
SHOWER/STORM CHANCES LOWER AND APPEARS TO BE ON TRACK AS MID LEVEL
CAP SHOULD BECOME FAIRLY SUBSTANTIAL. SUBSIDENCE FROM THE UPPER
LEVEL RIDGE SHOULD ALSO INHIBIT STORM ACTIVITY.
&&
.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z TUESDAY EVENING)
ISSUED AT 744 PM EDT MON JUN 17 2013
CDFNT DROPPING SOUTHWARD ACROSS SRN MI/NE IL THIS EVE WITH SCT
SHRA/TS IN VCNTY OF THE FRONT. FROPA EXPECTED AT SBN BY 05Z AND AT
FWA BY 08Z. LEFT TS OUT OF TAFS FOR TNGT AS INSTABILITY OVER NRN
INDIANA WK ATTM AND POTENTIAL FOR DESTABILIZATION LIMITED WITH
NIGHTFALL APCHG AND MCS OVER LWR OH VALLEY PREVENTING MUCH IN THE
WAY OF THETA-E ADVECTION IN ADVANCE OF THE FRONT. INSTEAD... CONTD WITH
VCSH WITH FROPA AT FWA AND FCST TEMPO -SHRA THIS EVE AT SBN DUE TO
PROXIMITY OF SHRA TO THE TERMINAL ATTM. MOISTENING OF BOUNDARY
LAYER BEHIND THE FRONT COULD LEAD TO SOME MVFR VSBYS TOWARD
MORNING AND PERHAPS SOME STRATUS CLOSER TO LAKE MICHIGAN AT SBN.
ALTHOUGH FRONT WILL BE SOUTH OF THE TERMINALS ON TUE WITH NELY SFC
FLOW... A FAIRLY STRONG VORT MAX EVIDENT IN WATER VAPOR LOOP OVER
ND THIS EVE IS EXPECTED TO MOVE INTO INDIANA TUE AFTN. THIS COULD
TRIGGER SOME TS OVER THE AREA TUE AFTN AS IT HAS UPSTREAM THIS
AFTN.
