AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
653 PM EDT WED AUG 19 2015
.AVIATION...
MOIST PRE-FRONTAL ENVIRONMENT WILL SUSTAIN A LOW POTENTIAL FOR
ADDITIONAL ISOLATED SHOWERS/THUNDERSTORMS THROUGH THE LATTER HALF OF
THE EVENING. GREATER POTENTIAL WILL ARRIVE AFTER MIDNIGHT...AS A
STRENGTHENING FRONTAL ZONE ENTERS THE REGION. THIS WILL LIKELY
RESULT IN AN EXPANDING COVERAGE OF SHOWERS...CONTAINING EMBEDDED
THUNDER. ENVIRONMENT WILL BE SUPPORTIVE OF AT LEAST PERIODIC
EPISODES OF HEAVIER RAINFALL...LEADING TO MVFR CONDITIONS. THIS
MOISTURE WILL EXIT TO THE EAST BY MID MORNING THURSDAY /10Z-12Z/.
GUSTY POST-FRONTAL SOUTHWESTERLY CONDITIONS WILL EMERGE AS DAYTIME
HEATING ENSUES ON THURSDAY. GUSTS INTO THE 25 KNOT RANGE FOR THE
AFTERNOON PERIOD.
FOR DTW...INCREASING COVERAGE OF SHOWERS EXPECTED DURING THE
OVERNIGHT PERIOD. WEAK INSTABILITY WILL MAINTAIN THE POTENTIAL FOR
SOME EMBEDDED THUNDERSTORMS. HOWEVER THE LOW PROBABILITY AND
QUESTIONABLE DURATION/TIMING WILL PRECLUDE ANY DEFINED MENTION AT
THIS STAGE. PERIODIC MVFR CONDITIONS AS THIS MOISTURE WORKS
THROUGH.
//DTW THRESHOLD PROBABILITIES...
* LOW FOR CEILING 5000 FT OR LESS PRIOR TO 04Z...HIGH OVERNIGHT...
MEDIUM ON THURSDAY.
* LOW FOR THUNDERSTORMS TONIGHT.

.PREV DISCUSSION...ISSUED 337 PM EDT WED AUG 19 2015
SHORT TERM...TONIGHT
MOIST ENVIRONMENT IN PLACE...AS 18Z DTX SOUNDING CHECKED IN PW VALUE
OF 1.66 INCHES...WITH SURFACE DEW PTS RUNNING IN THE UPPER 60S TO
LOWER 70S. MLCAPES OF 500-1000 J/KG HAVE BEEN ABLE TO GENERATING
PLENTY OF SHOWERS THIS AFTERNOON...BUT UPDRAFT STRENGTH/ACTIVITY HAS
NOT BEEN SUFFICIENT TO GENERATE MUCH IN THE WAY OF THUNDERSTORM
ACTIVITY (THROUGH 19Z) THUS FAR...AS MID LEVEL LAPSE RATES REMAIN
WEAK. ON FLIP SIDE...DESPITE THE GOOD COVERAGE OF SHOWERS...THIS
ACTIVITY IS NOT DOING A WHOLE LOT TO STABILIZE THE LOW LEVELS...AS
LATE AFTERNOON AUGUST SUNSHINE QUICKLY ALLOWING FOR SOME RECOVERY.
WITH MAIN COLD FRONT JUST BEGINNING TO MOVE INTO THE STATE LATE
TODAY...THE RAMPING UP OF BULK WIND SHEAR MAY PROVE SUFFICIENT TO
PRODUCING ISOLATED WIND DAMAGE BEFORE WE CAN STABILIZE AT THE
SURFACE POST SUNSET. 12Z NAM IS ACTUALLY SLOWEST WITH THE 0-4KM BULK
SHEAR RAMP UP...AFTER 00Z...AS VALUES REMAIN AROUND 20 KNOTS THROUGH
00Z.
ATTENTION TONIGHT IS THEN ON STRONG UPPER WAVE SLIDING THROUGH
NORTHWEST MISSOURI...HEADING TOWARD CHICAGO. THIS FEATURE AND
LONGWAVE TROUGH AXIS ATTEMPTING TO BECOME NEGATIVELY TILTED LOOKS TO
PROVIDE LARGE SCALE SUPPORT OVERNIGHT...WITH LOW LEVEL FGEN FLARE UP
AND RESIDUAL MOISTURE AXIS IN PLACE (PW VALUES 1.8-2.0 INCHES) TO
SUPPORT REDEVELOPMENT OF WIDESPREAD HEAVY RAIN SHOWERS AND
EMBEDDED THUNDERSTORMS. 12Z CANADIAN IS MOST AGRESSIVE WITH QPF
AMOUNTS...BUT INSTABILITY APPEARS TO BE TOO HIGH. ONE PLUS INCH
RAINFALL IS CERTAINLY POSSIBLE HOWEVER...WHICH COULD CAUSE SOME
URBAN FLOOD ISSUES (ADVISORY TYPE). LATE NIGHT CLEARING OF THE
COLD FRONT...TOWARD 12Z THURSDAY...EXPECTING TO HOLD MINS
PREDOMINATELY IN THE MID 60S. INTERESTLY...IF FLINT (KFNT) DOES
NOT FALL BELOW 73 DEGREES BEFORE MIDNIGHT...THE RECORD DAILY HIGH
MINIMUM WILL BE TIED...PREVIOUSLY SET 1934.
LONG TERM...THURSDAY THROUGH TUESDAY
UNSETTLED LONGWAVE PATTERN AS SEVERAL STRONG WAVES WORK THEIR WAY
ACROSS SOUTHERN CANADA THROUGH PERIOD. THE FIRST SYSTEM WILL BE
EXITING THE REGION ON THURSDAY WITH THE NEXT ONE MOVING IN ON
SUNDAY...PERSISTING THROUGH EARLY NEXT WEEK. THE STRENGTH OF THESE
SYSTEMS AND DEPTH OF LONGWAVE TROUGHS ALL POINT TOWARD COOLER THAN
NORMAL TEMPS FOR THE BULK OF THE EXTENDED.
THE COLD FRONT WORKING THROUGH LOWER MI WILL EXIT TO THE EAST EARLY
THURSDAY MORNING. MODELS ARE STILL ADVERTISING A SHORTWAVE LIFTING
NORTH ALONG THE FRONT THROUGH SE MI WHICH COULD RESULT IN AN
ENHANCED BAND OF SHOWERS IN THE THROUGH 15Z BEFORE THE FRONT PUSHES
EVERYTHING EAST. SUBSIDENCE IN THE WAKE OF THE FRONT WILL ATTEMPT TO
CLEAR SKIES FOR A FEW HOURS BEFORE BUT WILL QUICKLY FILL BACK IN AS
CAA IN THE BOUNDARY LAYER SETS UP A STOUT LL INVERSION WITH STEEP
LAPSE RATES FROM THE SFC TO AROUND 750MB...ALL AS THE WRAP AROUND
MOISTURE IN THE TRAILING TROUGH SWINGS THROUGH THE GREAT LAKES. WE
HAVE SEEN THIS SEVERAL TIMES ALREADY THIS SUMMER WITH SCATTERED
COVERAGE DEVELOPING AND TEMPERATURES ON THE LOW SIDE OF GUIDANCE.
USING MODELS AND CURRENT UPSTREAM OBS/SATELLITES...LOOKS GOOD FOR
THIS STRONG SYSTEM TO ONCE AGAIN FOLLOW SUITE. ISOLATED COVERAGE
ACROSS THE SOUTH WITH SCATTERED COVERAGE FURTHER NORTH LOOKS GOOD
WITH CLOUDY SKIES TIL SUNSET. EVEN THOUGH SFC HEIGHTS WILL BE ON THE
CLIMB THROUGH THE DAY AS RIDGING BUILDS IN FROM THE SW...EXCESSIVE
CLOUDS AND THERMAL TROUGH WILL LIMIT TEMPS TO THE LOW 70S. THE OTHER
ISSUE FOR THURSDAY WILL BE THE WIND. A TIGHT W-E GRADIENT AT THE
BASE OF THE TROUGH WILL TRAVERSE SE MI IN THE EARLY AFTERNOON WHICH
SHOULD RESULT IN WINDS GUSTING TO AROUND 25 KNOTS. UPSTREAM OBS
AGAIN SUPPORT THIS WITH WIDESPREAD OBS REPORTING GUSTS INTO THE MID
20 KNOT RANGE. HEIGHTS AT THE SFC AND AT 500MB WILL THEN BOTH BEGIN
TO CLIMB THURSDAY NIGHT THROUGH FRIDAY. DRIER AIR AND HIGH PRESSURE
WILL LEAD TO CLEARING SKIES AND SLIGHTLY WARMER TEMPS IN THE UPPER
70S.
HIGH PRESSURE WILL RESULT IN DRIER CONDITIONS FOR SATURDAY INTO MOST
OF SUNDAY. AN UPPER LEVEL NEGATIVELY TILTED TROUGH WILL PROGRESS
EASTWARD THROUGH THE NORTHERN MIDWEST REGION WITH THE ECMWF SHOWING
A STRONG UPPER LEVEL CLOSED LOW OVER NORTHERN MINNESOTA AT 06Z
SUNDAY. A SURFACE LOW PRESSURE SYSTEM MOVING EASTWARD THROUGH
SOUTHERN CANADA WILL BRING A TRAILING COLD FRONT THROUGH THE GREAT
LAKES REGION PROVIDING THE LIFT FOR CONVECTION SUNDAY NIGHT.
ALTHOUGH MODEL GUIDANCE IS SHOWING IMPRESSIVE LIFT...INSTABILITY MAY
BE LIMITED IN THE OVERNIGHT HOURS. FOLLOWING THIS FRONT...EXPECT
TEMPERATURES TO BE WELL BELOW AVERAGE. HIGH PRESSURE WILL BUILD INTO
THE AREA PROVIDING US WITH NO POPS FOR THE REMAINDER OF THE FORECAST
PERIOD.
MARINE...
A STRONG LOW PRESSURE SYSTEM LIFTING NORTH THROUGH THE WESTERN GREAT
LAKES WILL STEER THE FORECAST FOR THE NEXT COUPLE DAYS. SCATTERED
SHOWERS AND THUNDERSTORMS WILL PERSIST THROUGH THE OVERNIGHT BEFORE
A COLD FRONT PUSHES EAST THROUGH LAKE HURON THURSDAY MORNING. WINDS
CONTINUE TO BE A CONCERN ACROSS THE GREAT LAKES AS A TIGHT PRESSURE
GRADIENT HAS KEPT GUSTS ELEVATED TODAY NEAR 20 KNOTS. THE GRADIENT
WILL TIGHTEN FURTHER BEHIND THE FRONT ON THURSDAY LEADING TO
SOUTHWESTERLY FLOW GUSTING TO 25 KNOTS ACROSS ALL MARINE ZONES...AS
PER UPSTREAM OBSERVATIONS. FOR THAT REASON...SMALL CRAFT ADVISORIES
WERE EXPANDED ACROSS ALL NEARSHORE ZONES THURSDAY MORNING THROUGH
THE EVENING HOURS. OFF SHORE FLOW WILL MINIMIZE THE WAVE HEIGHTS IN
THE NEARSHORE ZONES WITH THE EXCEPTION OF SAGINAW BAY WHERE THE FLOW
WILL BE ALONG THE AXIS OF THE BAY ALLOWING WAVE TO BUILD.
