AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 118 AM EDT MON JUL 18 2011 .AVIATION... //DISCUSSION... A LARGE COMPLEX OF THUNDERSTORMS IS MAKING ITS WAY EAST EARLY THIS MORNING. AWIPS TIME OF ARRIVAL TOOL PROGS THE STORMS TO MAKE A STEADY SOUTHEAST TRACK THROUGH THE TAF SITES EARLY THIS MORNING REACHING MBS SHORTLY AFTER 07Z...AND FINALLY OVER THE METRO AIRPORTS SHORTLY AFTER 10Z. GIVEN THE UNCERTAINTY REGARDING THE SPEED AS THE STORMS ARE STILL SEVERAL HOURS AWAY...WILL PUT IN A 3 HOUR TEMPO GROUP TO CAPTURE THE MOST LIKELY TIMES THE LINE OF THUNDERSTORMS WILL TRACK OVER THE TAF SITES. UPSTREAM OBSERVATIONS INDICATE THE THUNDERSTORMS HAVE AT BEST DROPPED CIG VALUES TO MVFR...WITH VIS VALUES AROUND 1 MILE. LATER TODAY A WEAK FRONT MAY BRING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS TO THE TAF SITES THIS AFTERNOON AND THIS EVENING...HOWEVER COVERAGE AND CONFIDENCE ARE TOO LOW TO INCLUDE IN THE TAFS AT THIS TIME. FOR DTW...SHOWERS AND THUNDERSTORMS CURRENTLY OVER NORTHERN AND WESTERN MICHIGAN SHOULD MAKE THEIR WAY OVER THE METRO AIRPORT BETWEEN 10Z AND 13Z. THESE STORMS COULD BRING WIND GUSTS FROM THE NORTHWEST TO 40 KNOTS AS THEY PASS THROUGH THE AIRPORT. //DTW THRESHOLD THREATS... * MEDIUM CONFIDENCE IN THE COVERAGE AND TIMING OF THUNDERSTORMS THIS MORNING. * MEDIUM CONFIDENCE CIGS WILL FALL BELOW 5K FT THIS MORNING WITH SHOWERS AND THUNDERSTORMS. && .PREV DISCUSSION...ISSUED 1101 PM EDT SUN JUL 17 2011 UPDATE... THE MCS OVER WISCONSIN IS MAKING STEADY EASTWARD PROGRESS TOWARDS MICHIGAN LATE THIS EVENING. THE LATEST HRRR RUN SHOWS THE LINE OF STORMS MARCHING ALL THE WAY THROUGH SOUTHEAST MICHIGAN EARLY THIS MORNING...MAKING IT TO THE SAGINAW VALLEY AROUND 08Z AND THE METRO AREA AROUND 12Z. WHILE OTHER MODELS SUCH AS THE WRF AND NAM DO NOT HOLD THIS LINE TOGETHER...THEY ARE INITIALIZING VERY POORLY AND TO NOT HAVE THE CURRENT CONVECTION AS FAR SOUTH AS THE RADAR DATA SHOWS. DESPITE THE PROGRESS OF THE CONVECTION...INSTABILITY ACROSS OUR CWA IS MUCH LOWER THAN THAT OVER WISCONSIN WITH MLCAPE VALUES OF ONLY A FEW HUNDRED J/KG. THEREFORE WILL RAISE POPS ACROSS THE ENTIRE CWA FOR THE REST OF TONIGHT...HOWEVER WILL NOT GO CATEGORICAL AS THE SYSTEM COULD DISSIPATE WHEN IT REACHES MORE STABLE AIR IN PLACE ACROSS SOUTHEAST MICHIGAN. PREV DISCUSSION...ISSUED 357 PM EDT SUN JUL 17 2011 SHORT TERM...TONIGHT A VERY SMALL SHORTWAVE RIDGE FEATURE ON THE PERIMETER OF THE MUCH LARGER MID TO UPPER LEVEL RIDGE WILL BE IN PLACE OVER LOWER MICHIGAN THROUGH APPROXIMATELY 6Z. THE HEIGHT RISES ASSOCIATED WITH THIS SMALL FEATURE WILL CAUSE A SUBSIDENCE INVERSION TO LOWER IN THE 800-600MB RANGE. THIS WILL EFFECTIVELY BOLSTER THE CAP AND PROVIDE STABLE CONDITIONS. QUIET WEATHER IS EXPECTED THROUGH AT LEAST THE FIRST HALF OF THE PERIOD. A CONSOLIDATED ZONE OF MODEST 850-700MB CONVERGENCE AND 700-500MB DEFORMATION IS EXPECTED TO CARVE DOWN INTO SOUTHEASTERN MICHIGAN TONIGHT ON NORTHWESTERLY MEAN FLOW. THE BEST TIMING FOR THIS FORCING TO ENTER THE NORTHERN CWA IS AFTER 9Z TONIGHT. THERE IS ENOUGH MODEL AGREEMENT THAT WEAK MOISTURE/THETA E ADVECTION...NOTED AT 700MB...WILL COMMENCE BEHIND THIS FORCING AS WELL. THUS...THE IDEA THAT REMNANT CONVECTION FROM THE UPPER MISSISSIPPI RIVER VALLEY WILL SURVIVE THE TRIP INTO THE CWA TOWARDS MORNING IS FAVORED. WITH NO LOW LEVEL JET IN PLACE OVER SOUTHEASTERN MICHIGAN...CONVECTIVE ACTIVITY WILL BE OUTPACING THE BETTER THERMODYNAMIC INSTABILITY SUPPORT AND ACTIVITY SHOULD BE IN A DRAMATICALLY WEAKENED STATE BY TOMORROW MORNING. NO SEVERE WEATHER IS EXPECTED DURING THIS PERIOD. CONDITIONS WILL REMAIN MUGGY AND MILD OVERNIGHT...LOWER 70S FOR LOWS WITH HEAT INDICES LIKELY REMAINING IN THE MIDDLE TO UPPER 70 DEGREE RANGE. LONG TERM... MONDAY THROUGH NEXT SUNDAY COVERAGE AND INTENSITY OF THUNDERSTORMS WILL BE THE MAIN CONCERN IN THE FORECAST FOR MONDAY. OBSERVATIONS SO FAR TODAY SUPPORT STANDARD AND HIGH RESOLUTION MODEL DEPICTIONS OF ACTIVITY OVER THE NORTHERN PLAINS AND UPPER MIDWEST WITH GOOD AGREEMENT IN COVERAGE AND INTENSITY. THE GENERAL IDEA CALLS FOR THE USUAL DIURNAL CYCLE OF SURFACE BASED CONVECTION THROUGH PEAK HEATING THIS EVENING FOLLOWED BY FOLLOWED BY A COMPONENT OF NOCTURNAL DEVELOPMENT DURING THE NIGHT OVER THE UPPER MIDWEST AND UPPER MICHIGAN. THIS NOCTURNAL COMPONENT IS EXPECTED TO MOVE THROUGH SE MICHIGAN MONDAY MORNING WITH SCATTERED COVERAGE AND NOT MUCH MORE THAN STANDARD STRENGTH. THE MAIN LIMITING FACTOR FOR SEVERE POTENTIAL DURING THE MORNING WILL BE AN OVERALL LACK OF INSTABILITY OVER SOUTHERN LOWER MICHIGAN INTO WHICH THE ACTIVITY WILL BE MOVING, JUDGING MAINLY BY MODEL REPRESENTATIONS OF AVERAGE MID LEVEL LAPSE RATES AND ELEVATED INSTABILITY. THIS CONVECTION AND ASSOCIATED CLOUD COVER WILL COMPLICATE AFTERNOON AND EVENING CONVECTIVE TRENDS AS WELL BUT WITH ENOUGH BOUNDARY LAYER RECOVERY EXPECTED TO TAKE ADVANTAGE OF THE WEAK FRONT SHOWN SINKING SOUTHWARD INTO THE SAGINAW VALLEY BY EVENING. THIS SURFACE BOUNDARY, ASSOCIATED WITH LOW PRESSURE OVER NORTHERN ONTARIO AND QUEBEC, WILL SETTLE SOUTHWARD WITH THE HELP OF INCREASING NORTHWEST FLOW ALOFT AND COULD REPRESENT OUR BEST CHANCE FOR SEVERE WEATHER MONDAY AFTERNOON AND EVENING. THIS WILL BE HIGHLY DEPENDENT ON THE RECOVERY OF SURFACE BASED INSTABILITY ON THE HEELS OF MORNING ACTIVITY, WHICH LOOKS OVERDONE IN THE MODEL DATA DUE TO EXAGGERATED SURFACE DEWPOINT IN THE MID 70S AND EVEN UPPER 70S IN THE NAM OUTPUT. TUESDAY WILL SHAPE UP MUCH LIKE TODAY IN TERMS OF TEMPERATURE AND HUMIDITY. THE WEAK FRONTAL BOUNDARY IS EXPECTED TO WASH OUT AND LEAVE BEHIND A NEBULOUS PATTERN OF SURFACE HIGH PRESSURE THAT WILL BE SLIGHTLY LESS HUMID BUT NOT MUCH COOLER. MODEL AGREEMENT IS QUITE GOOD ON THE DEPICTION OF THE 850-700 MB THETA-E RIDGE DRIVEN TO OUR SOUTH AND WEST WHICH WILL HELP ENSURE DRY CONDITIONS IN OUR AREA. RETURN FLOW WILL LIKELY DEVELOP QUICKLY, HOWEVER, BY TUESDAY NIGHT INTO WEDNESDAY MORNING BUT FOCUSED MAINLY TO OUR NORTH INITIALLY. FOR NOW, THE PLAN IS TO BEEF UP CLOUD COVER WEDNESDAY BUT HOLD OFF ON RAIN CHANCES THAT MAY BE NEEDED AFTER ANOTHER CYCLE OR TWO OF MODEL CONSISTENCY. THE MAIN STORY HERE WILL BE A RETURN OF HEAT AND HUMIDITY WITH MAX TEMPS BACK INTO THE LOWER 90S AND HEAT INDEX INTO THE MID AND UPPER 90S. FROM THURSDAY ONWARD, THERE IS NOT MUCH TO CHALLENGE IN TERMS OF MODEL OUTPUT THAT MAINTAINS THE HOT AND HUMID THEME INTO THE WEEKEND. ALL OF THE LARGE SCALE FEATURES DIRECTING THE PATTERN REMAIN IN PLACE AND ARE SHOWN TO EVOLVE AS EXPECTED. CONFIDENCE IS IN THE HIGH SIDE WITH A SCENARIO SHOWING THE MAIN BAND OF WESTERLIES BRUSHING THROUGH THE NORTHERN GREAT LAKES FROM THE LONG WAVE TROUGH OVER THE WEST COAST AND INTO THE BROAD UPPER LOW ANCHORED BETWEEN NEWFOUNDLAND AND GREENLAND. THIS LEAVES THE BROAD UPPER RIDGE INTACT OVER THE CENTRAL U.S. WITH A STRONG EXTENSION INTO SE MICHIGAN. INCREASED SW WINDS WILL HELP REINFORCE THE HOT SURFACE AIR MASS IN THE REGION FROM THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY, ESPECIALLY THURSDAY WHICH COULD BE THE HOTTEST DAY OF THE STRETCH WITH THE LOWEST CHANCE OF DISRUPTION DUE TO CONVECTION BUT NOT SO MUCH FRIDAY. TRENDS IN MODEL SOLUTIONS FROM THE LAST COUPLE DAYS INDICATE MAINTENANCE OF THE WEST COAST LONG WAVE TROUGH VIA PACIFIC SHORT WAVE ENERGY THROUGH THE WEEKEND BUT WITH A TENDENCY TO KICK A STRONGER WAVE INTO CENTRAL CANADA. AS EXPECTED, THIS RESULTS IN A WEAK FRONT MOVING INTO LOWER MICHIGAN AT VARIOUS TIMES DURING THE WEEKEND, DEPENDING ON THE MODEL. THE 00Z ECMWF WAS THE ONLY HOLD OUT ON A SIMILAR SOLUTION BUT THE 12Z RUN HAS TRENDED A BIT TOWARD THE MAJORITY OF RUNS IN SUPPORT OF A SHOT AT BREAKING THE HEAT BY SUNDAY. MARINE... GOOD MARINE CONDITIONS CAN BE EXPECTED AGAIN THIS EVENING AS THE CENTRAL GREAT LAKES REMAIN BETWEEN HIGH PRESSURE NEAR THE EAST COAST AND A SLOW MOVING FRONT PUSHING SOUTH OUT OF CANADA. THIS WEAK FRONT WILL PROVIDE A FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS TO MOVE SOUTH ACROSS THE GREAT LAKES FROM TONIGHT THROUGH MONDAY NIGHT. THERE IS THE POTENTIAL FOR SOME OF THE STORMS TO BE STRONG ON MONDAY...ESPECIALLY FROM SOUTHERN LAKE HURON TO LAKE ERIE. HIGH PRESSURE WILL RETURN BEHIND THIS FRONT BRINGING FAVORABLE MARINE CONDITIONS AGAIN FOR TUESDAY. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
