AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
334 PM EDT TUE JUN 25 2013

.SHORT TERM...TONIGHT

MOIST AIRMASS IN PLACE...WITH SURFACE DEW PTS HOVERING AROUND 70
DEGREES. REMNANT THUNDERSTORM COMPLEX/MID LEVEL CIRCULATION WHICH
WAS OVER SOUTHERN WISCONSIN THIS MORNING IS MOVING THROUGH LOWER
MICHIGAN...AND THE EARLIER ARRIVAL HAS LIMITED THE INSTABILITY JUST
ENOUGH TO KEEP STORMS SUB SEVERE...AS MAXES HAVE STAYED AROUND 80
DEGREES ACROSS MANY LOCATIONS (THUS FAR). ONCE THIS DISTURBANCE
MOVES ON...850 MB WESTERLY JET/WINDS WILL BE DIMINISHING...AND THUS
LITTLE TO FOCUS/OR TRIGGER ADDITIONAL STORMS THIS EVENING OUTSIDE OF
SOME LINGERING MESOSCALE BOUNDARIES...AS WE RESIDE WITHIN THE
SUBSIDENCE WAKE. HOWEVER...INSTABILITY/MLCAPES REMAIN ON THE
UNCOMFORTABLY HIGH SIDE OVER THE NORTHERN OHIO VALLEY (2500-3500
J/KG)...WITH STILL SOME LATE DAY RECOVERY POSSIBLE ACROSS SOUTHEAST
MICHIGAN...AND CERTAINLY NOT ABANDONING CHANCE OF ADDITIONAL STRONG
TO SEVERE THUNDERSTORMS...AS ORGANIZED ACTIVITY CAN STILL GET GOING
OVER THE MIDWEST/ILLINOIS LATE THIS AFTERNOON (NOTED DISTURBANCE
PUSHING INTO NORTHERN ILLINOIS)...TRACKING EAST WITH THE MEAN FLOW.
THIS IS GIVEN SOME SUPPORT BY 17Z HIRES RUN.

AFTER MIDNIGHT...THE CHANCES SHOULD BE DIMINISHING FURTHER AS UPPER
LEVEL SHORTWAVE RIDGING IS ADVERTISED TO BE BUILDING IN...PER
NAM/GFS/REGIONAL GEM. WITH FAIR AMOUNT OF CLOUD COVER AND ELEVATED
DEW PTS...LOOKING AT MINS IN THE 65 TO 70 DEGREES...AS WINDS WILL BE
CALM/LIGHT.

&&

.LONG TERM...WEDNESDAY THROUGH TUESDAY

THERE HAS BEEN A VERY MEANINGFUL SHIFT IN MODEL SOLUTIONS (PER 12Z
RUNS OF NAM/GEM/GFS/UKMET) IN REGARDS TO THE EVOLUTION OF WEDNESDAY
AND WEDNESDAY NIGHT CONVECTIVE POTENTIAL. THE STRAIGHTFORWARD
EVOLUTION OF ONE LOW PRESSURE CENTER CROSSING THE AREA AS STRONG
SHORTWAVE TOPS THE UPPER RIDGE TO OUR WEST AND SWEEPS THROUGH THE
AREA HAS BEEN COMPLICATED BY PERSISTENT CONVECTION ACTIVITY DURING
THE PAST 24 HOURS THAT WILL BE ONGOING TO ONE DEGREE OR ANOTHER
TONIGHT. ESSENTIALLY...THE WEST TO EAST BOUNDARY ACROSS THE SOUTHERN
GREAT LAKES/NORTHERN OHIO VALLEY IS NOW FORECAST TO REMAIN
QUASI-STATIONARY NOW THAT MESOSCALE INFLUENCES HAVE RE-ENFORCED ITS
CURRENT POSITION...WITH A SOUTHERN LOW PRESSURE CENTER TRACKING
ALONG IT AS THE MAIN SHORTWAVE AND ASSOCIATED NORTHERN LOW SHEARS
INTO THE NORTHERN GREAT LAKES.

WHILE THE GENERAL SCENARIOS FORECAST BY THESE MODELS VARY ON THE
AMOUNT OF CONVECTION THAT WILL BLEED NORTH INTO THE CWA TO THE NORTH
OF THE MAIN CONVERGENCE NEAR THE MICHIGAN/OHIO STATE LINE...THERE
HAS UNARGUABLY BEEN A NOTABLE SOUTHWARD SHIFT IN THE BEST FOCUS FOR
CONVECTION...AND WILL HAVE TO ADJUST THE FORECAST TO INCLUDE A
TIGHTER NORTH TO SOUTH GRADIENT FOR THE BEST RAIN CHANCES. WHILE
CHANCES LOOK BE REMAIN QUITE HIGH IN SOUTHERN AREAS SOUTH OF
DETROIT...LOCATIONS NORTH OF I 69 MAY ONLY SEE VERY ISOLATED
ACTIVITY....WITH POINTS IN BETWEEN THESE TWO EXTREMES PRETTY MUCH
STILL UP IN THE AIR. WHILE DRAMATIC CHANGES TO FORECAST ARE NOT
PLANNED...WILL LOWER POPS NORTH OF M 59 OR SO WHILE MAINTAINING
LIKELY WORDING FURTHER SOUTH.

UNDER THIS SCENARIO...THE BEST POOL OF INSTABILITY WILL BE CUT OFF
FROM MUCH OF LOWER MICHIGAN...LIMITING THE RISK OF SEVERE WEATHER.
COUPLE THIS WITH MUCH LESS FAVORABLE WIND FIELDS NORTH OF THE OHIO
VALLEY (OR LOW TRACK IF YOU PREFER)...AND THE SLIGHT RISK FOR SVR
WEATHER WILL ONLY REACH NORTH INTO THE FAR SOUTHERN CWA.

BEYOND WEDNESDAY NIGHT...UPPER PATTERN TRANSITIONS FROM NEAR ZONAL
OVER THE AREA TO NORTHWEST FLOW AS UPPER TROUGH BEGINS TO AMPLIFY
OVER THE EASTERN CONUS. BY THE WEEKEND...THIS TROUGH EVOLVES INTO A
BROAD UPPER LOW POSITIONED OVER/NEAR THE GREAT LAKES. THIS PATTERN
WILL MAINTAIN UNSETTLED CONDITIONS WITH NEARLY DAILY SHOWERS OR A
FEW THUNDERSTORMS SCATTERED ABOUT DURING THE AFTERNOON/EVENING.

WILL MAINTAIN RELATIVELY MILD CONDITIONS ON THURSDAY/FRIDAY AS WEST
TO NORTHWEST FLOW SHOULD STILL ASSIST IN DAYTIME WARMING BEFORE THE
COOLEST POOL OF AIR SHIFTS OVER THE AREA BY SATURDAY. HIGHS SHOULD
BE IN AND AROUND 80...WITH 70S COMMON THEREAFTER INTO EARLY NEXT
WEEK.

&&

.MARINE...

WARM AND HUMID AIR WILL CONTINUE TO RESIDE OVER THE GREAT LAKES FOR
THE NEXT COUPLE OF DAY...PROVIDING MOSTLY STABLE CONDITIONS. THIS
WILL KEEP WINDS AND WAVES ON THE LOW SIDE OUTSIDE OF ANY
THUNDERSTORM THAT MAY DEVELOP. THE FORECAST CONTINUES TO CARRY A LOW
CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THE END OF THE
WEEK....BUT WINDS WILL ARE EXPECTED TO REMAIN LIGHT AND VARIABLE.

&&

.AVIATION...ISSUED 1206 PM EDT TUE JUN 25 2013

//DISCUSSION...

BREAKS DEVELOPING IN THE CLOUDS EARLY THIS AFTERNOON SHOULD GENERATE
ENOUGH INSTABILITY TO MAINTAIN SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS LATE THIS AFTERNOON INTO THIS EVENING. LATEST
MODELS OVERNIGHT INTO TOMORROW SUGGEST UPPER LEVEL RIDGING
BUILDING INTO SOUTHEAST MICHIGAN...AND THUS LIMITING THE CHANCES
FOR CONVECTION. KEPT A DECK OF CLOUDS (3-5 KFT) IN TONIGHT...BUT
IF THESE CLOUDS DO NOT PERSIST THEN FOG IS BIG CONCERN TOWARD
SUNRISE.

FOR DTW...
VARIABLE CLOUDS THIS AFTERNOON (4-5 KFT) WITH INCREASING CHANCE OF
THUNDERSTORMS. SHOWER/POSSIBLE THUNDERSTORM ACTIVITY THIS EVENING
THEN ENDING...WITH PROBABLE CEILINGS BELOW 5000 FEET OVERNIGHT.
CONFIDENCE IS LOW IN THE TIMING AND CHANCES OF ADDITIONAL STORMS
TOMORROW.

//DTW THRESHOLD THREATS...

* MEDIUM CONFIDENCE IN THUNDERSTORMS LATE TODAY/EARLY THIS EVENING.

* LOW TO MEDIUM CONFIDENCE IN CEILINGS BELOW 5000 FT OUTSIDE OF
  THUNDERSTORMS.

SOUTH. THERE WILL BE A SLIGHT CHANCE OF SEVERE STORMS WITH THE
BEST CHANCE SOUTH OF I 94. THE MAIN HAZARDS WILL BE DAMAGING WIND
GUSTS TO 60 MPH AND HAIL TO ONE INCH IN DIAMETER...WITH HEAVY RAIN
ALSO LIKELY. SOME OF THIS ACTIVITY WILL LINGER INTO WEDNESDAY NIGHT

SCATTERED THUNDERSTORMS WILL REMAIN POSSIBLE INTO THURSDAY AND
FRIDAY AS AN UPPER LOW PRESSURE SYSTEM SHIFT SOUTH INTO THE AREA.
THIS ACTIVITY WILL OCCUR MAINLY DURING THE AFTERNOON AND EVENING
