Area forecast discussion, Aug 30, 5:59 PM EST, 13 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 659 PM EDT FRI AUG 30 2013 .AVIATION... //DISCUSSION... THE THUNDERSTORMS SLOWLY PUSHING TO THE SOUTHEAST IN ADVANCE OF A WEAK COLD FRONT HAVE BEEN STRUGGLING SOMEWHAT AS A RESULT OF STRONG MID LEVEL CAPPING OVER SE MI. NONETHELESS...RECENT RADAR/SATELLITE TRENDS HAVE BEEN SUGGESTING THAT THE LOW LEVEL CONVERGENCE IS SUFFICIENT IN GENERATING AT LEAST A SCT-BKN LINE OF SHOWERS/THUNDERSTORMS. THESE SHOULD CONTINUE TO ADVANCE TO THE SOUTHEAST ACROSS THE TERMINALS DURING THE REMAINDER OF THE EVENING AS THE CAPPING INVERSION SLOWLY WEAKENS. THE PASSAGE OF THE FRONT WILL BE MARKED BY A VEERING OF THE WIND TO THE W-NW. POST FRONTAL OBSERVATIONS ACROSS NORTHERN MI STRONGLY SUPPORT MODEL SOUNDINGS WHICH DEPICT A LOW STRATUS DECK OVERSPREADING THE TERMINALS IN THE WAKE OF THE FRONT. ADDED MOISTURE FLUX OFF LAKE HURON LATER TONIGHT COUPLED WITH A LOWERING INVERSION MAY RESULT IN LOW END MVFR AND/OR IFR CEILINGS BY DAYBREAK SAT. FOR DTW...THE CAPPING INVERSION OVER METRO IS A BIT STRONGER. THIS RAISES SOME CONCERN THAT CONVECTION WILL BYPASS DTW TO THE NORTH. CONFIDENCE IS NOT GREAT ENOUGH TO REMOVE THUNDERSTORMS FROM THE TAF. GIVEN THE TIMING OF THE FRONT AND RECENT RADAR TRENDS...THE TIMING OF THUNDERSTORMS HAS BEEN PUSHED BACK TO THE 02Z TO 04Z TIME FRAME. //DTW THRESHOLD THREATS... * MEDIUM CONFIDENCE THUNDERSTORMS WILL IMPACT DTW THIS EVENING. * HIGH CONFIDENCE CEILINGS WILL DROP BELOW 5000 FT AFTER 06Z. && .PREV DISCUSSION...ISSUED 355 PM EDT FRI AUG 30 2013 SHORT TERM...THIS AFTERNOON AND TONIGHT THE MID-LEVEL CAP DRAWN NORTHWARD AHEAD OF THE SHORTWAVE DIGGING ACROSS THE GREAT LAKES HAS WON OUT SO FAR TODAY. THIS WAS EVIDENCED BY THE RAPID DECAY OF THIS MORNING'S CONVECTIVE COMPLEX OVER NORTHERN LOWER MICHIGAN, BUT ALSO BY THE SHALLOW AND SHORT-LIVED UPDRAFTS THAT HAVE SPORADICALLY POPPED UP WITHIN THE MID-LEVEL MOISTURE PLUME THROUGHOUT THE AFTERNOON. AVAILABLE 100-MB MLCAPE NOW EXCESS OF 1500 J/KG COMBINED WITH 0-6KM BULK SHEAR IN EXCESS OF 40 KTS AND IMPROVING MID-LEVEL MOISTURE QUALITY DOES OFFER IMPROVED PROSPECTS FOR CONVECTION THIS EVENING COMPARED TO EARLIER TODAY. BUT THIS IS REALLY ONLY THE CASE ALONG AND NORTH OF THE I-69 CORRIDOR, WHERE THE AFOREMENTIONED PARAMETERS ARE FAVORABLY MAXIMIZED (LOCALLY) AND SUPPORTIVE OF AT LEAST A LOW-END SEVERE WIND/HAIL THREAT FOR THE REMAINDER OF THE DAYTIME HEATING PERIOD. ELSEWHERE, CONCERNS RELATED TO CAPPING REMAIN SINCE THE WARM LAYER CENTERED AROUND 700MB WILL BE GOING NOWHERE DURING PEAK HEATING AND CONVECTION IS UNLIKELY TO ARRIVE IN DETROIT METRO AND SURROUNDING AREAS UNTIL THE ONSET OF NOCTURNAL COOLING. FURTHER SUPPORTING THIS REASONING IS THE COMPLETE VOID OF ANY DEVELOPMENT, INCLUDING RESPECTABLE CU, ALONG THE PRONOUNCED OUTFLOW BOUNDARY THAT HAS BEEN PROPAGATING SOUTH THROUGH THE WESTERN CWA THIS AFTERNOON. IT HAS THEREFORE BECOME EXCEEDINGLY DIFFICULT TO JUSTIFY A POP ANY HIGHER THAN 30 TO 40 PERCENT FOR THOSE AREAS. FINALLY, LOW-LEVEL COLD ADVECTION IN THE WAKE OF TONIGHT'S SLOWLY MOVING FRONT WILL FAVOR A PARTIAL TO BROKEN COVERAGE OF STRATUS WHICH WILL HELP MAINTAIN TEMPERATURES IN THE MID TO UPPER 60S FOR MOST OF THE AREA. COOLER AIR WILL BEGIN TO MAKE INROADS INTO THE NW PORTION OF THE CWA BY EARLY SATURDAY MORNING. LONG TERM... SUNDAY THROUGH NEXT FRIDAY SATELLITE IMAGERY AND SURFACE ANALYSIS TODAY BACKS THE IDEA OF THE WEAK SURFACE COLD FRONT MAKING IT SOUTH OF THE OHIO BORDER SATURDAY MORNING. THE SHALLOW NATURE OF THE FRONTAL ZONE DOES, HOWEVER, KEEP A CHANCE OF RAIN IN THE FORECAST FOR SOUTH SECTIONS OF THE REGION THROUGH THE DAY. WV IMAGERY TODAY SUGGESTS MID LEVEL SUBSIDENCE TRIALING THE UPPER LEVEL SHORT WAVE OVER THE NORTHERN GREAT LAKES COUPLED WITH AN ARM OF MODERATE SURFACE HIGH PRESSURE TRAILING THE FRONT WILL BE STRONG ENOUGH TO NUDGE THE SURFACE BOUNDARY SOUTH OF THE OHIO BORDER SHORTLY AFTER SUNRISE SATURDAY. THE SURFACE WIND SHIFT WILL BE SOUTH OF THE OHIO BORDER BUT THE NEW 12Z MODEL DATA REVEALS A SHALLOW ENOUGH SLOPE IN THE FRONT FOR THE 850-700 MB ZONE TO BRUSH THE SOUTH FOUR COUNTIES DURING THE DAY. THE MODELS ALSO INDICATE A RIPPLE OF LOW PRESSURE SLIDING ALONG THE FRONT THAT COULD BRING AN UPTICK IN RAIN CHANCE DURING THE AFTERNOON. THAT GENERAL IDEA IS IN ALL OF THE MODEL SOLUTIONS BUT NO SURPRISE WITH CONSIDERABLE SPREAD IN THE SPECIFICS. DRY CONDITIONS ARE PLANNED FOR THE M-59 CORRIDOR NORTH THROUGH THE TRI CITIES AND NORTHERN THUMB BUT POST FRONTAL LOW CLOUDS WILL BE PLENTIFUL THROUGH MID AFTERNOON WITH MAX TEMPS STRUGGLING INTO THE LOWER 80S. THE FRONT WILL LINGER SOUTH OF THE OHIO BORDER THROUGH SATURDAY NIGHT BEFORE RETURNING NORTH AS A WARM FRONT SUNDAY. THIS WILL BE FORCED BY THE NEXT LOW PRESSURE SYSTEM IN THE CANADIAN ROCKIES TODAY AS IT REACHES NORTHERN ONTARIO SUNDAY. MODEL PERFORMANCE ON THIS SYSTEM HAS BEEN SOLID OVER THE LAST SEVERAL MODEL CYCLES WITH REGARD TO THE MASS FIELDS BUT IT IS A TOUGH CALL ON THE MOISTURE FIELDS. LOW LEVEL MOISTURE TRANSPORT IS LESS EFFECTIVE FOR ELEVATED CONVECTION DURING THE DAYTIME, WHICH SUGGESTS THE NAM IS OVERDONE ON MOISTURE AND QPF WHILE THE DRIER SOLUTIONS LOOK MORE REPRESENTATIVE FOR SURFACE BASED ACTIVITY DURING THE AFTERNOON. PASSAGE OF THE UPPER LEVEL TROUGH AND COLD FRONT SUNDAY NIGHT WILL THEN PROVIDE ENOUGH FORCING TO TIP THE FORECAST FROM CHANCE TO LIKELY, AT LEAST FOR SHOWERS AS THE SYSTEM PASSES THROUGH DURING THE NIGHT MAKING THUNDERSTORM POTENTIAL MORE LIMITED. AFTER MORNING CLOUDS, LABOR DAY WILL TURN OUT OK WITH COOLER AND LESS HUMID AIR MOVING AGGRESSIVELY INTO THE REGION. A BROAD AREA OF SURFACE HIGH PRESSURE WILL THEN DOMINATE CONDITIONS THROUGH MID WEEK BEFORE GLOBAL MODEL SOLUTIONS ADVERTISE A STRONGER COLD FRONT WEDNESDAY INTO THURSDAY. AT THIS POINT, THE SYSTEM IS COLD ENOUGH TO BRING A PREVIEW OF FALL TEMPERATURES INTO THE GREAT LAKES TO START THE WEEKEND. MARINE... SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE WATERS THIS EVENING...A FEW OF WHICH COULD BE SEVERE OVER LAKE HURON. CONDITIONS WILL OTHERWISE REMAIN RATHER TRANQUIL THROUGH THE WEEKEND WITH LIGHT WINDS AND JUST A CHANCE OF THUNDERSTORMS. A PASSING COLD FRONT WILL THEN ALLOW GUSTY NORTHWEST TO SPREAD ACROSS THE WATERS EARLY NEXT WEEK.
