Hail and Damaging Winds in Michigan, September 5, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
335 PM EDT WED SEP 5 2012

.SHORT TERM...THIS EVENING AND TONIGHT

CONVECTIVE DEBRIS HAS BEEN WIDESPREAD ACROSS SOUTHEAST MICHIGAN FOR
MOST OF THE DAY, SIGNIFICANTLY LIMITING HIGH TEMPERATURES AND
INHIBITING DESTABILIZATION. THIS IS PARTICULARLY THE CASE ACROSS THE
SOUTHERN HALF OF THE CWA WHERE SHOWERS/TSTORMS HAS RESULTED IN
PARTIAL OVERTURNING AND ADDITIONAL OPAQUE CLOUDCOVER. MOST OF THE
INSTABILITY THEREFORE REMAINS CONFINED TO NORTHERN PORTIONS OF THE
AREA WHERE ONLY PARTIAL CLOUD COVER HAS BEEN OBSERVED FOR THE
MAJORITY OF THE PEAK HEATING PERIOD. AN 18Z DTX SOUNDING REVEALED
THAT A MODERATELY FAVORABLE THERMODYNAMIC ENVIRONMENT WAS IN PLACE
ACROSS THE AFOREMENTIONED CORRIDOR WHERE ML CAPE VALUES HAVE
INCREASED TO 1500-2000 J/KG THIS AFTN. IN ADDITION, 0-6KM BULK SHEAR
OF 35-40 KTS CHARACTERIZED BY A DEEP LAYER OF VEERING WINDS IN THE
LOWEST 5000 FT AGL IS ALSO PRESENT. IN FACT, THE POTENTIAL FOR
ROTATING UPDRAFTS HAS ALREADY BEEN REALIZED IN A CELL THAT FORMED
OVER NORTHERN MIDLAND COUNTY AND TRACKED ACROSS SAGINAW BAY EARLIER
THIS AFTERNOON. THE POTENTIAL FOR SEVERE/ROTATING UPDRAFTS WILL
REMAIN UNTIL THE LOSS OF DIURNAL HEATING THIS EVENING WITH A PRIMARY
THREAT OF MARGINALLY SEVERE HAIL. DAMAGING WINDS WILL ALSO BE
POSSIBLE WHILE THE TORNADIC THREAT WILL REMAIN MARGINAL. THE LACK OF
ANY WELL-DEFINED FORCING MECHANISM ALONG WITH A FAIRLY STOUT 850MB
CAPPING INVERSION WILL LIMIT COVERAGE FOR THE REST OF THE AFTERNOON.
THEREFORE, ONLY HIGH CHANCE POPS REMAIN IN PLACE NORTH OF I-69 WHERE
ISOLATED SEVERE POTENTIAL WILL PERSIST UNTIL 00Z.

A LULL CAN THEN BE EXPECTED UNTIL LATE TONIGHT WHEN A COLD FRONT,
WHICH IS NOW GATHERING ITSELF OVER THE UPPER MS VALLEY/WESTERN GREAT
LAKES, IS FORECAST TO ACCELERATE INTO THE FORECAST AREA. THIS WILL
OCCUR AS A CORRIDOR OF MID-LEVEL HEIGHT FALLS SPREADS INTO THE
NORTHERN LAKES AND THE PARENT SURFACE LOW UNDERGOES RAPID DEEPENING
AS IT LIFTS FROM LAKE SUPERIOR INTO ONTARIO. LOW LEVEL FORCING ALONG
THE FRONT WILL COUPLE WITH STEEP H7-3 LAPSE RATES TO PRODUCE AN
INCREASING LIKELIHOOD OF SHOWERS AND THUNDERSTORMS AS THE FRONT
APPROACHES AFTER MIDNIGHT. ISOLATED SEVERE WILL AGAIN BE A
POSSIBILITY IN THE VERY EARLY MORNING HOURS ON THURSDAY AS PARCELS
LIFTED FROM THE INVERSION SHOULD HAVE ACCESS TO AT LEAST 1000-1500
J/KG OF ELEVATED CAPE WITH HAIL ONCE AGAIN POSING THE PRIMARY
THREAT. CLOUDS AND SOUTHERLY WINDS WILL MAINTAIN LOW TEMPERATURES
SOLIDLY IN THE 60S.

&&

.LONG TERM...THURSDAY THROUGH NEXT WEDNESDAY

LOW LEVEL DRY AIR ADVECTION WILL BE ONGOING DURING THE DAY THURSDAY
WITH MID LEVEL SUBSIDENCE OVERSPREADING THE SOUTHERN GREAT LAKES.
THE NAM SOLUTION IS AN OUTLIER IN MAINTAINING REMNANT SFC LOW
PRESSURE AND AMPLE INSTABILITY OVER METRO DETROIT INTO EARLY
AFTERNOON. GIVEN THE EXPECTED UPPER AIR PATTERN AND CURRENT SURFACE
PATTERN...THIS SOLUTION DOES NOT SEEM REASONABLE. THUS PREFER TO
MAINTAIN JUST A CHANCE OF EARLY MORNING CONVECTION ACROSS THE
EXTREME EASTERN SECTIONS OF THE FORECAST AREA TO ACCOUNT FOR ANY
RESIDUAL ACTIVITY LEFT OVER FROM TONIGHT. THE DRY AIR ADVECTION AND
MID LEVEL SUBSIDENCE WILL THEN LEAD TO A CLEARING TREND DURING THE
DAY. AFTERNOON INSOLATION SHOULD OFFSET THE WEAK LOW LEVEL COLD AIR
ADVECTION SOME AND ALLOW AFTERNOON HIGHS TO RISE INTO THE UPPER
70S/LOWER 80S.

THE 12Z MODEL SUITE CONTINUE TO SHOW LONG WAVE TROUGH AMPLIFICATION
ACROSS THE UPPER MIDWEST AND GREAT LAKES FRIDAY AND FRI NIGHT. THESE
MOST RECENT MODEL RUNS HAVE FOLLOWED SUIT WITH THE SIGNIFICANTLY
MORE PROGRESSIVE TREND NOTED IN THE 00Z RUNS. IT APPEARS THAT
STRONGER AND FASTER MID LEVEL IMPULSES WILL ROTATE OUT OF THE ALASKA
UPPER VORTEX...SUPPRESSING THE DEGREE OF MID LEVEL RIDGING OVER
WESTERN CANADA AND ALLOWING MID LEVEL RIDGING TO BUILD BACK INTO
THE EASTERN US NEXT WEEK. INTENSIFICATION OF AN UPPER JET MAX OVER
THE NRN GREAT LAKES FRIDAY NIGHT IN ADVANCE OF THE DEEPENING LONG
WAVE TROUGH WILL STRENGTHEN LOW TO MID TROPOSPHERIC FRONTOGENESIS
OVER THE GREAT LAKES. THE INCREASED BAROCLINICITY WILL LEAD TO SFC
CYCLOGENESIS ACROSS THE EASTERN GREAT LAKES ON SATURDAY. SUBTLE
DIFFERENCES IN THE AMPLITUDE OF THIS WAVE WILL IMPACT WHERE THE
BETTER FGEN SETS UP AND HOW LONG THIS LARGER SCALE FORCING
PERSISTS INTO THE DAY SATURDAY. RECENT MODEL TRENDS TOWARD A MORE
PROGRESSIVE SYSTEM SUGGEST THE BETTER FGEN ARRIVING LATE FRIDAY
INTO FRIDAY NIGHT...WITH THE BULK OF LARGER SCALE FORCING PASSING
TO THE EAST BY LATE FRI NIGHT/SAT MORNING. THIS STILL SUPPORTS A
GOOD CHANCE OF WIDESPREAD RAIN FRIDAY NIGHT...BUT WARRANTS
LOWERING RAIN CHANCES ON SATURDAY. RESIDUAL LOW LEVEL MOISTURE
COUPLED WITH STEEPENING MID LEVEL LAPSE RATES ON
SATURDAY...COURTESY OF THE MID LEVEL COLD POOL MOVING
OVERHEAD...WILL SUPPORT A CHANCE OF SOME DIURNALLY DRIVEN SHOWERS.
GOOD COLD AIR ADVECTION UNDER GUSTY N-NW WINDS TO THE WEST OF THE
DEEPENING SFC LOW /850MB TEMPS DROPPING INTO THE SINGLE DIGITS/
WILL RESULT IN A RATHER COOL AND BREEZY DAY...WITH TEMPS LIKELY
STUCK IN THE 60S.

A SECONDARY MID LEVEL IMPULSE DIVING INTO THE BASE OF THE LONG WAVE
TROUGH OVER THE SOUTHERN GREAT LAKES IS SHOWN BY ALL THE MODEL
SOLUTIONS FOR SUNDAY. ADDITIONAL COLD AIR ADVECTION ALOFT WILL AGAIN
SUPPORT STEEP MID LEVEL LAPSE RATES AND WARRANTS ANOTHER CHANCE OF
SOME DIURNALLY DRIVEN SHOWERS SUNDAY /POSSIBLY SOME ISOLATED
THUNDERSTORMS/. WITH THE MORE PROGRESSIVE FLOW...SFC HIGH PRESSURE
SHOULD BUILD IN BY MONDAY...LEADING TO COOL AND DRY CONDITIONS TO
START OFF THE WEEK. MID LEVEL HEIGHTS AND RETURN FLOW SHOULD HOWEVER
LEAD TO A WARMING TREND TUES-WED.

&&

.MARINE...

SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS EVENING, MAINLY OVER
SAGINAW BAY AND THE NEARSHORE WATERS OF LAKE HURON. THESE STORMS
WILL POSE A THREAT OF MARGINALLY SEVERE HAIL, WIND, AND POTENTIALLY
WATERSPOUTS. ANOTHER ROUND OF THUNDERSTORMS, POTENTIALLY CONTAINING
MARGINALLY SEVERE HAIL, WILL BE POSSIBLE AGAIN LATE TONIGHT ACROSS
ALL WATERS AS A COLD FRONT APPROACHES THE AREA. NORTHWEST WINDS AND
WAVES WILL ALSO INCREASE BEHIND THE FRONT ON THURSDAY...BUT ARE
EXPECTED TO BELOW HEADLINE CRITERIA.

&&

.AVIATION...ISSUED 1232 PM EDT WED SEP 5 2012

//DISCUSSION...

BOUNDARY LAYER MOISTURE HAS BEEN SLOW TO MIX OUT THIS OUT THIS
MORNING RESULTING IN IFR CLOUDS/VSBYS PERSISTING LONGER THAN
EXPECTED. AT ISSUANCE TIME, HOWEVER, VISIBILITIES HAVE IMPROVED AND
CEILINGS HAVE LIFTED ABOVE 5KFT FOR NEARLY ALL LOCATIONS. ANY
LINGERING LOW CLOUDS WILL CONTINUE TO MIX OUT OVER THE NEXT HOUR OR
TWO.

PERIODIC THUNDERSTORM ACTIVITY WILL THEN HAVE AT LEAST THREE
WELL-DEFINED OPPORTUNITIES TO AFFECT THE TAF SITES OVER THE NEXT 18
HOURS. THE FIRST IS ASSOCIATED WITH ONGOING ACTIVITY ACROSS SOUTHERN
LOWER MICHIGAN THAT WILL POTENTIALLY IMPACT THE AIRFIELDS FROM KPTK
SOUTH AROUND 18Z. ADDITIONAL THUNDERSTORMS, AIDED BY MODERATE
DIURNAL DESTABILIZATION, WILL BE POSSIBLE IN THE 20-00Z TIME FRAME
THIS AFTERNOON FOLLOWED BY ANOTHER ROUND IN THE 06Z-12Z WINDOW AS
THE COLD FRONT FINALLY BEGINS TO PUSH THROUGH SOUTHEAST MICHIGAN.
CONFIDENCE IN ANY ONE LOCATION SEEING THUNDER REMAINS LOW FOR ALL
THREE INSTANCES, THOUGH THE BEST CHANCE WILL BE THIS EVENING DURING
PEAK HEATING WHEN THUNDERSTORM INTENSITY AND COVERAGE IS FORECAST TO
BE GREATEST. TSTORMS WILL THEREFORE BE HANDLED ON AN AMENDMENT
BASIS AS INDIVIDUAL THREATS PRESENT THEMSELVES. AWAY FROM
SHOWER/TSTORM ACTIVITY, CONDITIONS WILL REMAIN VFR WITH A LOW
VFR/SUB-5KFT CEILING OF DIURNAL CU POSSIBLE THIS AFTERNOON.

//DTW THRESHOLD THREATS...

* LOW CONFIDENCE THAT A THUNDERSTORM WILL IMPACT KDTW

* MEDIUM CONFIDENCE OF CEILINGS AROUND 5000 FEET BY THIS EVENING.
