AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
323 PM EDT SAT JUN 27 2015
.SHORT TERM...THIS EVENING AND TONIGHT
LAST PHASE OF THE MATURE CYCLONE AFFECTING THE REGION IS ABOUT TO
COMMENCE OVER SOUTHEAST LOWER MICHIGAN. DEFORMATION AXIS IS
REORIENTING OVER SOUTH CENTRAL LOWER AND REPOSITIONING FARTHER EAST
WHERE THE BETTER THETA-E OVERLAP IS PRESENT IN THE 850-700MB LAYER.
DECENT ELEVATED CONVECTIVE RESPONSE OCCURRED NEAR THE MI/IN/OH STATE
INTERSECTION THIS AFTERNOON CLOSER TO THE MID/UPPER LEVEL DRYING.
THIS WILL SERVE AS THE ANCHOR POINT FOR THE DEFORMATION SIGNAL
THROUGH THE EVENING HOURS. EXPECT THE GREATEST CONTINUOUS RESPONSE
WILL EXIST ALONG A FLINT TO ADRIAN LINE - MORE FEEDER WAVE STRUCTURE
IS EXPECTED TO THE EAST OF THE DEFORMATION AXIS. LATEST GUIDANCE
SUITE SUGGESTS THE DEFORMATION WILL BECOME OVERSTRETCHED AND DECAY
TOWARD MIDNIGHT AS IT SLOWLY WORKS EASTWARD TOWARD THE CANADIAN
BORDER. AFTER WHICH...SCATTERED SHOWERS ARE STILL POSSIBLE UNTIL
DAYBREAK ACROSS THE FAR EAST.
THE OTHER MAIN SYSTEM CHARACTERISTIC IMPRESSING ITSELF UPON THE
REGION IS THE STRONG NORTH/NORTHEAST WINDS. THE BEST GUST POTENTIAL
WILL BE LATE THIS AFTERNOON INTO THIS EVENING AS THE LOW CONTINUES
TO DEEPEN - FORCING 50KTS AT 925MB. HOWEVER...NOT EXPECTING MIXING
WILL REALLY BE AN ISSUE TO GET UP INTO THE REALLY STRONG LOW-LEVEL
FLOW. THE SURFACE PRESSURE GRADIENT SHOULD SUFFICE ALONE TO
MAINTAIN THE FIRM WIND FIELD. AS SUCH...WILL CONTINUE TO ADVERTISE
HIGH WATER LEVELS ALONG THE LAKE ERIE AND LAKE ST CLAIR SHORELINES
WITH THE ONSHORE GALES FORCING ON TOP OF THE RECENTLY HIGHER WATER
LEVELS.
&&
.LONG TERM...
OUR WELL DEFINED MID LEVEL CIRCULATION/500 MB LOW WILL SLOWLY WORK
THROUGH THE EASTERN GREAT LAKES ON SUNDAY. THE KEY WORD IS
SLOWLY...AS HEIGHTS WILL GRADUALLY RISE. DEEP MOISTURE TO START THE
DAY (POSSIBLE SPRINKLES/LEFTOVER LIGHT RAIN SHOWERS EAST OF U.S 23
)...AS 1000-500 MB MEAN RH STARTS OUT IN EXCESS OF 80 PERCENT. WITH
ALL THE RAIN TODAY AND TONIGHT SATURATING THE GROUND AND THE
STUBBORN CYCLONIC FLOW...WOULD EXPECT MOSTLY CLOUDY SKIES OVER
EASTERN AREAS THROUGH AT LEAST THE EARLY AFTERNOON HOURS BEFORE
RIDGING/DRYING TAKES BETTER HOLD. HOWEVER...CONFIDENCE IN THE
DEVELOPING AFTERNOON SUNSHINE IS NOT HIGH ENOUGH TO GO FOR MAXES OF
80 DEGREES WHICH IS THE AIRMASS POTENTIAL (850 MB TEMPS APPROACHING
12 C)...AND THUS WILL CARRY MID TO UPPER 70S INSTEAD...IN LINE WITH
LATEST MET GUIDANCE.
ANOTHER SEASONABLY STRONG UPPER WAVE CURRENTLY DIVING SOUTHEAST
THROUGH SOUTHERN MANITOBA WILL TRACK INTO THE UPPER MISSISSIPPI
RIVER VALLEY TONIGHT/SUNDAY MORNING...THEN MAKING THE TURN TO THE
EAST DURING THE DAY INTO THE NORTHERN OHIO VALLEY SUNDAY
EVENING/NIGHT. YET MORE UPPER LEVEL ENERGY COMING DOWN FROM THE SAME
LOCATION MONDAY MORNING CARVING OUT HIGHER AMPLITUDE TROUGH AXIS
OVER THE WESTERN GREAT LAKES MONDAY EVENING AS UPPER LEVEL RIDGE
ALONG THE WEST COAST BUILDS INTO WESTERN CANADA.
AS A RESULT...DEVELOPING RAIN SHOWERS APPEAR LIKELY MONDAY
AFTERNOON/EVENING OVER SOUTHEAST MICHIGAN AS THE CLOSED 500 MB LOW
OR OPEN UPPER LEVEL TROUGH AND ASSOCIATED SURFACE LOW SLOWLY TRACKS
THROUGH SOUTHERN LOWER MICHIGAN...WITH SUFFICIENT MOISTURE AS PW
VALUES RISE TO AT LEAST 1.5 INCHES...POTENTIALLY AROUND 1.75 INCHES
PER 12Z NAM. MORE SUBSTANTIAL INSTABILITY LOOKS TO BE REMAINING
SOUTH OF THE BORDER ALONG WITH THE MID LEVEL JET...BUT STRENGTH OF
LOW LEVEL JET/MOISTURE ADVECTION CERTAINLY WARRANTS A CHANCE OF
THUNDERSTORMS. MUCH LIKE THIS LAST SYSTEM...MOVEMENT WILL BE
SLOW...AS THE GFS STILL SHOWING TROUGH AXIS LINGERING OVERHEAD ON
TUESDAY...IN LINE WITH THE 12Z EURO. THE CHANCE FOR SHOWERS AND
THUNDERSTORMS WILL CONTINUE DURING THE DAY. HIGHS LOOK TO BE IN THE
70S BOTH TUESDAY AND WEDNESDAY...ULTIMATELY DEPENDENT ON CONVECTION
INITIATION TIMES.
NORTHWEST UPPER FLOW OVER THE LOCAL AREA ON WEDNESDAY AS THE CENTER
OF THE UPPER TROUGH CONTINUES TO SHIFT EASTWARD. THIS IS EXPECTED TO
LEAD TO HIGH PRESSURE AT THE SURFACE AND DRY CONDITIONS. THERE ARE
SIGNS THAT THE TROUGH WILL REESTABLISH ITSELF OVER THE WESTERN GREAT
LAKES FRIDAY INTO NEXT WEEKEND COINCIDENT WITH AN INCREASE IN PWATS.
WILL CARRY CHANCE POPS FRIDAY NIGHT INTO NEXT WEEKEND. TEMPS LOOK TO
REMAIN BELOW NORMAL WITH THE TROUGHINESS IN PLACE.
.
&&
.MARINE...
STRONG LOW PRESSURE HAS JUST ABOUT FINISHED BOTTOMING OUT OVER
NORTHEAST OHIO THIS AFTERNOON. SUBSEQUENTLY...THE STRONGEST WINDS
ACROSS LAKE ERIE AND LAKE ST CLAIR HAVE LIKELY ALREADY OCCURRED. AS
WINDS SHIFT TO A MORE NORTHERLY DIRECTION THIS EVENING...STILL
EXPECT WINDS TO INCREASE TO GALE FORCE ACROSS EXTREME SOUTHERN LAKE
HURON...BUT THESE STRONGER WINDS WILL BE THE EXCEPTION...WITH THE
OVERALL TREND OF GRADUALLY DIMINISHING WINDS OCCURRING THIS
EVENING...AND ESPECIALLY TONIGHT. DECREASING WINDS WILL CONTINUE ON
SUNDAY...WITH WINDS 10 KNOTS OR LESS BY SUNDAY EVENING AS A WEAK
SURFACE RIDGE ARRIVES. THE NEXT LOW PRESSURE SYSTEM LOOKS TO BE
TRACKING THROUGH SOUTHERN LOWER MICHIGAN MONDAY NIGHT...BRINGING
ANOTHER ROUND OF SHOWERS AND POSSIBLE THUNDERSTORMS. DEPENDING ON
THE STRENGTH OF THE LOW...SOUTHWEST WINDS SOUTH OF THE LOW OVER LAKE
ST CLAIR AND LAKE ERIE COULD GUST TO 25 KNOTS...WITH POSSIBLE
NORTHWEST GUSTS TO AROUND 25 KNOTS BEHIND THE LOW OVER LAKE HURON ON
TUESDAY.
&&
.AVIATION...ISSUED 1256 PM EDT SAT JUN 27 2015
NORTHWEST QUADRANT OF THE MATURE CYCLONE AFFECTING THE REGION IS
CURRENTLY REDEFINING WHERE THE BEST OVERLAP IN MOISTURE AND
FORCING WILL PERSIST THROUGH THE LATE AFTERNOON AND EVENING HOURS.
EXPECTATION IS FOR THE BEST FORCING TO RESIDE NEAR KFNT - WITH
MORE PERIODIC RAIN FOR THE DETROIT AREA TERMINALS.
REGARDLESS...LOWER CEILINGS WILL PERSIST IN SOME FASHION THROUGH
MUCH OF THE TERMINAL FORECAST PERIOD. GUSTY NORTHEAST TO NORTH
WINDS WILL ALSO PLAGUE THE AREA PRIOR TO MIDNIGHT...WITH GUSTS
APPROACHING 30 KNOTS.
FOR DTW...CEILINGS WILL HOVER SLIGHTLY ABOVE 1KFT UNTIL THE NEXT
BATCH OF RAIN WASHES ACROSS - AFTER WHICH A PROLONGED PERIOD OF SUB-
1KFT CEILINGS IS EXPECTED. RAINFALL MAY TEMPORARILY LOWER
VISIBILITIES BELOW 3SM - BUT NOT VERY CERTAIN. LIKEWISE...COULD
ALSO BE A STRAY LIGHTNING STRIKE.
//DTW THRESHOLD PROBABILITIES...
* HIGH IN CEILINGS BELOW 5000 FEET THROUGH 16Z SUNDAY.
* LOW IN A THUNDERSTORM AFFECTING THE NEAR TERMINAL AIRSPACE.
