AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
1217 AM EDT TUE JUL 14 2015
.AVIATION...
INCREASED COVERAGE OF THUNDERSTORMS OVER WESTERN LOWER MICHIGAN
SUPPORTS A MENTION IN THE TERMINAL FORECASTS DURING THE EARLY
MORNING HOURS. SOME WEAKENING IS EXPECTED AS THE CONVECTION MOVES
EASTWARD BUT SOME GUSTY WEST WIND AND IFR IN HEAVY DOWNPOURS ARE
LIKELY AT EACH LOCATION UNTIL THE CLUSTERS EXIT EASTWARD TOWARD
SUNRISE. ANOTHER PERIOD OF ENHANCED STRATUS/STRATO-CU AND PERHAPS
ADDITIONAL SCT -SHRAS LATE IN THE FORECAST PERIOD. WINDS WILL VEER
FROM SW TONIGHT TO W DURING THE MORNING NW/N DURING AFTN/EVENING
WITH THE PASSAGE OF THESE SYSTEMS.
FOR DTW...THUNDERSTORMS ARE LIKELY IN THE 07Z-11Z PERIOD AND PERHAPS
AGAIN LATER IN THE FORECAST AS SEVERAL WAVES PIVOT THROUGH REGION.
IFR RESTRICTION IS LIKELY WITH LOWER VFR/MVFR POSSIBLE AGAIN LATE IN
FORECAST WITH SECOND WAVE.
//DTW THRESHOLD PROBABILITIES...
* MEDIUM FOR CEILINGS AOB 5000 FT TONIGHT/MORNING. LOW TUESDAY
EVENING.
* MEDIUM FOR THUNDERSTORM DEVELOPMENT TONIGHT/MORNING AND LOW DURING
AFTERNOON.

.PREV DISCUSSION...ISSUED 354 PM EDT MON JUL 13 2015
SHORT TERM...THIS EVENING AND TONIGHT
A STRUNG OUT STRETCHING DEFORMATION FILLAMENT HAS BEEN STRUGGLING TO
PUSH EASTWARD TODAY AND HAS BEEN THE MAIN ITEM OF NOTE. ENOUGH
THERMODYNAMIC SUPPORT EXISTED DESPITE RELATIVELY STABLE LOWER LEVELS
TO ALLOW FOR MULTIPLE...INNOCUOUS WAKE LOW STRUCTURES TO CAUSE
DISRUPTIONS AND LOWER PREDICTABILITY TO THE SURFACE WIND FLOW AROUND
MIDDAY. A SURVEY OF SURFACE OBSERVATIONS THIS AFTERNOON SUGGESTS
THIS POTENTIAL HAS ENDED. A FAIRLY IMPRESSIVE BRANCH OF UPPER LEVEL
WESTERLIES SANDWHICHED BETWEEN TWO UPPER LEVEL RIDGE CENTERS REMAINS
IN PLACE OVER PORTIONS OF THE MISSISSIPPI AND OHIO RIVER VALLEYS.
THE FORECAST IS FOR THIS UPPER LEVEL JET MAXIMUM TO REMAIN SOUTH AND
WEST OF DETROIT THROUGH THE OVERNIGHT. THE LACK OF FLOW WILL MAKE
THE DEFORMATION SLUGGISH IN ITS EXIT OVER THE NEXT 3 HOURS. BETTER
SURFACE HEATING AND MIXED LAYER GROWTH AHEAD OF THE DEFORMATION WILL
ALSO GIVE A CHANCE FOR A SHOWER OR RUMBLE OF THUNDER YET LATE THIS
AFTERNOON.
THE ITEM OF IMPORTANCE FOR TONIGHT WILL BE SHORTWAVE ENERGY THAT
WILL STREAM OUT OF MINNESOTA AND WISCONSIN...ALONG WITH THE ABSOLUTE
VORTICITY MAXIMUM THAT IS OVER LAKE SUPERIOR. MAIN FORCING LATE
TONIGHT WILL BE DIFFERENTIAL CYCLONIC VORTICITY ADVECTION OCCURING
IMMMEDIATELY IN ADVANCE OF THE SHORTWAVE ENERGY AS IT PUSHES
DIRECTLY INTO SOUTHEASTERN MICHIGAN. FORECAST THETA E PLAN VIEW
CHARTS SHOW SOME MINOR THETA E RIDGE ORGANIZING AMIDST THE LARGER
SCALE DIFFUSE QUASI-WARM SECTOR. MAINTAINED THE PREVIOUS FORECAST OF
LIKELY POPS FOR LATE TONIGHT. THE EVENT WILL BE HEAVILY DEPENDENT ON
UPSTREAM CONVECTION PUSHING/ADVECTING DOWNSTREAM INTO THE AREA.
THERE IS AGAIN LOW PREDICTABILITY ON COVERAGE GIVEN LACK OF UPPER
LEVEL JET SUPPORT...BUT ENOUGH THERMAL FORCING EXISTS TO SUPPORT
LIKELY TO NUMEROUS COVERAGE DURING THE 8-12Z TIMEFRAME.
LONG TERM...TUESDAY THROUGH NEXT MONDAY
AN AMPLIFYING MID LEVEL TROUGH NOW ROTATING ACROSS LAKE SUPERIOR/NE
MINNESOTA WILL ROTATE ACROSS LAKE HURON AND SE MI ON TUESDAY. THE
ASSOCIATED MID LEVEL COLD POOL COUPLED WITH MODEST DAYTIME
DESTABILIZATION WILL SUPPORT A HEALTHY COVERAGE OF SHOWERS AND SOME
THUNDERSTORMS. BOUNDARY LAYER CONVERGENCE IN THE VICINITY OF THE SFC
LOW /FCST TO TRACK ACROSS THE ERN HALF OF THE FORECAST AREA/ AND
NUMEROUS SFC FRONTS/TROUGH AXES WITHIN A RELATIVELY DEEP MOIST LAYER
WILL FURTHER SUPPORT A HIGH LIKELIHOOD OF RAIN SHOWERS. THE DEGREE
OF DIURNAL DESTABILIZATION WILL OF COURSE REMAIN DEPENDENT ON THE
COVERAGE OF MORNING SHOWERS AND LOW CLOUDS. MODEL SOLUTIONS BRING
SFC DEWPOINTS UP TOWARD 70 DEG TUES MORNING...WHICH MAY BE A BIT
OVERDONE TAKING INTO ACCOUNT SFC DEWPOINTS ACROSS THE UPPER GREAT
LAKES THIS AFTERNOON. ASSUMING AT LEAST A BRIEF PERIOD OF DAYTIME
HEATING BOOSTING HIGHS IN THE MID/UPPER 70S AND SFC DEWPOINTS IN THE
UPPER 60S...0-1KM ML CAPE WILL LIKELY FALL SHY OF 1K J/KG. THIS
ALONG WITH THE BETTER MID LEVEL WIND FIELDS SLIDING JUST SOUTH OF
THE STATE WILL DRASTICALLY LIMIT THE POTENTIAL FOR ANY STRONG/SEVERE
STORMS ON TUES.
SHOWERS WILL END ABRUPTLY FROM NORTH TO SOUTH ACROSS THE FORECAST
AREA TUES EVENING AS A DRY CONTINENTAL AIRMASS ADVANCES ACROSS THE
AREA IN THE WAKE OF THE ASSOCIATED COLD FRONT. THIS COOLER AND DRIER
AIR WILL BE DRIVEN INTO THE AREA IN ADVANCE OF A 1020MB SFC HIGH
BUILDING INTO THE NRN GREAT LAKES TUES NIGHT INTO WEDNESDAY. A POST
FRONTAL N-NE GRADIENT WILL LEAD TO A PERIOD OF RATHER GUSTY WINDS
TUES NIGHT INTO WED MORNING FOLLOWING FROPA...ESPECIALLY ALONG THE
LAKE HURON SHORELINE. POST FRONTAL SHALLOW COLD AIR ADVECTION WILL
LIMIT WED AFTERNOON MIXING DEPTHS...SUPPORTING HIGHS MAINLY IN THE
70S WITH UPPER 60S EXPECTED ALONG THE LAKE HURON SHORELINE. THE SFC
HIGH WILL SETTLE INTO THE SRN GREAT LAKES WED NIGHT...SETTING UP
OPTIMAL RADIATIONAL COOLING CONDITIONS. THIS WILL SUPPORT WED NIGHT
MINS WELL DOWN INTO THE 50S.
THE END OF THE WEEK AND INTO THE WEEKEND WILL FEATURE INCREASINGLY
WARM TEMPERATURES ALONG WITH CHANCES FOR PRECIPITATION. THE START
OF THE EXTENDED FORECAST ON THURSDAY WILL BE DRY AS THE AREA RESIDES
IN UPPER LEVEL RIDGING. THIS RIDING WILL NOT HOLD FOR VERY LONG AS
NUMEROUS SHORTWAVES ROTATE THROUGH THE UPPER LEVEL FLOW COME FRIDAY.
MODELS AS OF RIGHT NOW ARE SHOWING THE BETTER CHANCES FOR PRECIP ON
FRIDAY AND MONDAY AS MORE PROMINENT SHORTWAVES SLIDE ACROSS THE
GREAT LAKES REGION...HOWEVER LIKE USUAL ISSUES WITH TIMING WILL COME
INTO PLAY. COMFORTABLE TEMPERATURES FELT EARLIER IN THE WEEK WILL
GIVE WAY TO WARMER CONDITIONS AS TEMPS RISE INTO THE LOW TO MIDDLE
80S BY THE END OF THE WEEKEND.
MARINE...
LOW PRESSURE WILL TRACK ACROSS LAKE HURON LATE TONIGHT THROUGH TUES
MORNING...CAUSING A GRADUAL VEERING OF THE WINDS FROM SSE TO NW BY
TUES AFTERNOON. THE GRADIENT WILL INCREASE TUES AFTERNOON THROUGH
TUES NIGHT AS THE LOW DEPARTS TO THE EAST AND HIGH PRESSURE BUILDS
INTO LAKE SUPERIOR. THIS ALONG WITH NEUTRAL TO SLIGHTLY UNSTABLE
CONDITIONS OVER THE LAKES WILL LEAD TO GUSTY N-NE WINDS TUES NIGHT
INTO AT LEAST WED MORNING...ESPECIALLY ON LAKE HURON AND SAGINAW
BAY. SMALL CRAFT ADVISORIES MAY BE NEEDED UNDER THESE CONDITIONS.
WINDS AND WAVES WILL THEN DIMINISH TUES NIGHT AS THE HIGH PRESSURE
EXPANDS INTO THE SOUTHERN GREAT LAKES.
