NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 28, 6:18 AM EST, 5 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 718 AM EDT FRI JUN 28 2013 .AVIATION... //DISCUSSION... LOOKS LIKE A MIX OF IFR... MVFR AND VFR CONDITIONS TO START THE TAF CYCLE AS LATE NIGHT CONVECTION HAS INCREASED CLOUD COVER OVER MOST AREAS PREVENTING MUCH IN THE WAY OF FOG FORMATION. CIGS WILL LIFT THROUGH THE EARLY AFTERNOON BEFORE INCREASING COVERAGE OF SHOWERS AND THUNDERSTORMS DEVELOPS DURING THE AFTERNOON AND EVENING. A SLOW MOVING LOW PRESSURE SYSTEM OVER THE EASTERN GREAT LAKES WILL DRIFT SOUTHWARD FRIDAY NIGHT AND PULL A TRAILING TROUGH THROUGH SE MI. THIS WILL SHIFT THE WINDS FROM WESTERLY TO NORTHERLY AND LIKELY BRING ABOUT ANOTHER ROUND OF PATCHY FOG PENDING SHOWER ACTIVITY AND CLOUD COVER. FOR DTW... THOUGH MVFR VISIBILITY SHOULD IMPROVE THIS MORNING TO VFR OUTSIDE OF SHOWER ACTIVITY...MVFR CEILINGS WILL HOLD INTO THE AFTERNOON HOURS. ANOTHER ROUND OF SHOWERS IS ANTICIPATED DURING THE AFTERNOON INTO FRIDAY EVENING...BUT MUCH LESS INTENSE THAN THURSDAY AFTERNOON. //DTW THRESHOLD THREATS... * MEDIUM CONFIDENCE ON CEILING BELOW 5000 FEET THROUGH SATURDAY MORNING. && .PREV DISCUSSION...ISSUED 344 AM EDT FRI JUN 28 2013 SHORT TERM...TODAY AND TONIGHT COMPLEX MESOSCALE PATTERN CONTINUES FOR ANOTHER DAY. THE LONGWAVE TROUGH THAT BEGAN TO DEVELOP OVER THE GREAT LAKES REGION ON THURSDAY WILL DEEPEN THROUGH TONIGHT AS RIDGING OVER THE WEST COAST STEEPENS THE NW FLOW PATTERN OVER THE STATE SENDING A SERIES OF SHORTWAVES DOWN THE PIPELINE AND TOWARD SE MI. IN ADDITION TO THESE SHORTWAVES...RESIDUAL BANDS OF VORTICITY WILL BE ROTATING AROUND THE DEVELOPING UPPER LOW IN THE TROUGH WESTWARD TOWARD SE MI. MODELS FAIRLY CONSISTENT WITH THE STRONGEST MID LEVEL HEIGHT FALLS FORMING OVER THE SOUTHERN ONTARIO/QUEBEC BORDER BY LATE FRIDAY NIGHT. MEANWHILE A SECOND WEAKER AREA OF LOW PRESSURE WILL CONTINUE DIVING SOUTHWARD INTO THE TN VALLEY. WHILE THE UPPER LEVEL PATTERN RECONFIGURES ITSELF...ELONGATED SFC LOW EXTENDING NW FROM PA WILL STALL AS A SECOND LOW TRACKS TOWARD IT. MORAL OF THE STORY IS THAT THERE ARE PLENTY OF FEATURES TO AID IN CONVECTION ONCE AGAIN TODAY/TONIGHT. THE CHALLENGE WILL BE TO TIME THESE FEATURES AND BEST CHANCES FOR CONVECTION. THE HRRR...ALONG WITH LOWER RES MODELS... ADVERTISES A ROUND OF MORNING CONVECTION ON THE LEAD EDGE OF A SHORTWAVE DIVING THROUGH THE SW PORTION OF OUR CWA. THE MORE WIDESPREAD CONVECTION SHOULD DEVELOP IN THE AFTERNOON AS THE TRAILING SFC TROUGH EXTENDING FROM LAKE ERIE UP TO THE SOO DROPS DOWN THROUGH THE THUMB. THIS TIMING WILL BE FAVORABLE AS IT WILL GIVE AMPLE TIME FOR DAYTIME HEATING TO HELP FUEL THE STORMS. MUCAPE WILL RISE UP TO 1500 J/KG TOWARD THE OH BORDER BUT WILL DROP THROUGH THE MORNING IN THE THUMB DOWN AROUND 500 K/KG AS THE TROUGH INCHES SOUTHWARD. THERE IS LITTLE FLOW IN THE MID LEVELS TO PROVIDE MUCH ORGANIZATION BUT THE STORMS THAT DO DEVELOP WILL BE CAPABLE OF STRONG WIND GUSTS AND HEAVY RAIN. WITH THE HIGH RAINFALL TOTALS ON THURSDAY...WILL NEED TO KEEP AN EYE ON ANY STORMS THAT TRACK NEAR THESE AREAS TODAY. TEMPERATURES WILL BE LOWER THAN WE HAVE BEEN DEALING WITH FOR THE PAST WEEK AS NORTHERLY FLOW OFF LAKE HURON AND ABUNDANT CLOUD COVER WILL KEEP MOST AREAS IN THE MID 70S. LONG TERM...SATURDAY THROUGH THURSDAY MODELS IN GOOD AGREEMENT WITH THE OVERALL PATTERN FOR THE WEEKEND AND INTO EARLY NEXT WEEK. RELATIVELY POTENT JET FROM THE NORTHERN PLAINS WILL CONTINUE TO CARVE OUT A TROF OVER THE GREAT LAKES/EASTERN U.S. EVENTUALLY CUTTING OFF AN UPPER LOW OVER THE LOWER LAKES/OH AND TN VALLEYS. MODELS DO HAVE SOME DIFFERENCES WILL INDIVIDUAL SHORTWAVES...MOST NOTABLY THE NAM/S HANDLING OF THE SHORTWAVE ENTERING NY AND NEW ENGLAND THIS MORNING. WILL BE LEANING TOWARD THE OTHER MODELS WITH THIS PARTICULAR SHORTWAVE WHICH KEEPS THE ENERGY MORE OVER THE ONTARIO/QUEBEC BORDER REGION RATHER THAN THE NAM/S DEPICTION OF DROPPING IT INTO SOUTHERN MI. BESIDES THESE SHORTWAVES...THE AVAILABLE MOISTURE AND VERY MODEST INSTABILITY... THERE IS LITTLE FORCING NOTED. THE SHEAR AXIS THAT EXTENDED FROM LAKE SUPERIOR TO THAT MAIN SHORTWAVE MOVING FROM NY TO THE ONTARIO/QUEBEC BORDER THIS MORNING...WILL FINALLY BE PUSHING THROUGH SOUTHERN LOWER MI ON SATURDAY. THERE WILL BE PLENTY OF MOISTURE AVAILABLE WITH PW UP TO 1.4 OR 1.5 INCHES. MODEL SOUNDING ARE MOIST-ADIABATIC ALL THE WAY UP. WILL BE GOING WITH LIKELY POPS IN THE SOUTH...BUT KEEP THE CHANCE POPS FOR THE NORTHERN THIRD AS DRIER AIR DOES ADVECT IN ON THE SUBSIDENCE SIDE OF THAT SHEAR AXIS. GIVEN THE LIMITED CAPE...WILL KEEP THE IDEA OF SHOWERS LIKELY WITH A CHANCE OF THUNDERSTORMS. BY SUNDAY THE TWO MAIN PIECES OF ENERGY WILL BE OVER THAT ONTARIO/QUEBEC BORDER REGION AND DIVING INTO THE TN VALLEY AS THE TROF AXIS/UPPER LOW WILL BE JUST SOUTHEAST OF THE FORECAST AREA. THIS SHOULD LEAD TO THE DRIEST DAY AS THE DRY AIR ADVECTION CONTINUES. WILL KEEP THE SMALL CHANCE IN THE FAR SOUTHEAST GIVEN THE PROXIMITY TO THE MAIN TROF AND MOISTURE AXIS. THEN BY MONDAY...THE TN VALLEY ENERGY MOVES NORTHWARD INTO OHIO AS THE EASTERN SEABOARD RIDGE STRENGTHENS. THIS WILL SHIFT THE MOISTURE AND TROF AXIS EVER SO SLIGHTLY WESTWARD AND HAVE INCREASED THE CHANCE OF SHOWERS AND STORMS FOR THE SOUTHEAST HALF OF THE FORECAST AREA. FOR THE EXTENDED PERIOD...THE STRENGTHENING EASTERN SEABOARD RIDGE WILL CONTINUE TO PUSH THE UPPER LOW FARTHER WEST. ANOTHER GOOD PIECE OF ENERGY SHOULD BE ROTATING AROUND THE EAST SIDE OF THE UPPER LOW...RIGHT OVER LOWER MICHIGAN ON TUESDAY AND THUS THE HIGHEST POPS IN THE EXTENDED. 00Z GFS AND ECMWF BOTH WANT TO BRING A CANADIAN PRAIRIE LOW DOWN INTO THE NORTHERN AND HIGH PLAINS ALONG WITH FASTER FLOW DEVELOPING OVER ONTARIO TO KICK OUT OUR UPPER LOW. THIS SHOULD BE A SLOW TRANSITION ON WEDNESDAY AND ON THE 4TH...AND WILL KEEP WITH THE UNSETTLED SENSIBLE WEATHER IN THE FORECAST. MARINE... BROAD AREA OF LOW PRESSURE WILL RESIDE OVER THE GREAT LAKES INTO THE WEEKEND. THIS WILL PROVIDE SEVERAL CHANCES FOR SHOWERS AND THUNDERSTORMS FOR THE NEXT FEW DAYS. THE STRONGER THUNDERSTORMS WILL BE CAPABLE OF PRODUCING WIND GUSTS UP TO 35 KNOTS. A FRONT WILL DROP THROUGH THE EASTERN GREAT LAKES TONIGHT LEADING TO A GENERAL INCREASE IN NORTHERLY FLOW AS COOLER AIR MOVES ACROSS THE LAKE. WAVES WILL BUILD ON SATURDAY UP TO AROUND 4 FEET OVER SOUTHERN LAKE HURON WITH THE FAVORABLE FETCH AND THEN WILL HOLD AROUND 3 FEET INTO NEXT WEEK. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE.
