NWS Detroit, MI wrote its last area forecast discussion before the first event at Jun 7, 6:27 PM EST, 4 hours 18 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 727 PM EDT SAT JUN 7 2008 .AVIATION... MAIN CONCERN IN THE SHORT RUN IS CONVECTIVE COMPLEX MOVING OVER LAKE MICHIGAN PROPAGATING EASTWARD DURING THE OVERNIGHT HOURS... AND HOW FAR IT CAN GET BEFORE WEAKENING INTO A LARGE MASS OF SHOWERS WITH ISOLATED THUNDERSTORMS. THERE REMAINS ENOUGH LOW LEVEL MOISTURE IN PLACE OVER SOUTHEAST MICHIGAN TO SUPPORT CONVECTION THIS FAR EAST... BUT STRONGER CONVECTION WILL CONTINUE TO REDEVLOP ON THE SOUTHWEST/WEST FLANK OF THE COMPLEX ALONG THE COLD FRONT IN MINNESOTA AND WISCONSIN THROUGH THE EVENING AND OVERNIGHT HOURS. SO WILL KEEP VFR CONDITIONS WITH INCREASING MID AND HIGH LEVEL CLOUDINESS IN THE TAFS THIS EVENING AND BRING IN A 2-3 HOUR PERIOD OF LIGHT RAIN INTO THE NORTHERN TAF SITES LATER TONIGHT PRE-SUNRISE. COULD ALSO SEE SOME LIGHT FOG THOSE SITES POST-SUNRISE FOR A FEW HOURS. HAVE UPPED WINDS IN THE TAFS FOR SUNDAY AFTERNOON AS WE SHOULD BE ABLE TO EASILY MIX DOWN GUSTS TO 25 OR 30 KNOTS PROVIDED WE BREAK INTO ENOUGH SUNSHINE... WHICH WE SUSPECT WILL HAPPEN BY MID AFTERNOON. FOR LATE IN THE PERIOD... HAVE MENTIONED THE LIKELIHOOD OF THUNDERSTORMS IN THE NORTHERN TAFS WITH THE APPROACH OF THE BOUNDARY LATE SUNDAY AFTERNOON AND EVENING - AND SUSPECT THESE COULD BE RATHER ROBUST PROVIDED WE DONT SUFFER TOO MUCH MID LEVEL WARMING FOLLOWING LATENT HEAT RELEASE FROM TONIGHTS CONVECTION COMPLEX. && .PREV DISCUSSION...ISSUED 325 PM EDT SAT JUN 7 2008 SHORT TERM...TONIGHT CLOUDS ACROSS THE SOUTH HALF OF THE CWA FINALLY THINNING OUT AS MCS OVER THE OHIO VALLEY WEAKENS...AND THE FLOW BECOMES A BIT MORE WESTERLY OVER THE CENTRAL GREAT LAKES. AS OF 18Z...MLCAPES WERE 1000 J/KG WITH SURFACE BASED CAPES OF 2000+ J/KG OVER MUCH OF SOUTHEAST MICHIGAN. HOWEVER...ACAR FLIGHTS OUT OF KDTW CONTINUED TO SHOWED THE WARM CAPPING HOVERING BETWEEN 725/750 MB...WITH TEMPS IN THE LOWER TEENS. PRONOUNCED SURFACE RIDGING HAS ALSO BEEN PRESENT OVER WESTERN LOWER MICHIGAN...PREVENTING ANY ACTIVITY FROM DEVELOPING OFF THE LAKE MICHIGAN BREEZE THUS FAR. THOUGHTS HAVE NOT CHANGED MUCH FROM EARLIER UPDATE...AND WILL JUST MAINTAIN CHANCES POPS TONIGHT. ORGANIZING MCS OVER THE WESTERN GREAT LAKES REMAINS THE MOST CONCERNING FEATURE...BUT CORFIDI VECTORS ARE NO LONGER FORECASTED TO BE FORWARD PROPAGATING THIS EVENING/TONIGHT...AND COMPLEX WILL PROBABLY JUST BACK BUILD WITH THE MOIST INFLOW OF MID 70 DEW POINTS CONTINUING AND THE GREATEST INSTABILITY RESIDING OVER THE MIDWEST. ANY SUBTLE HEIGHT FALLS TONIGHT LOOK TO BE OVER NORTHERN LOWER MICHIGAN...AND STILL THINK THE NORTH THIRD OF THE CWA STANDS THE BEST CHANCE OF SEEING PRECIPITATION WITH THE BEST 850/700 MB MOISTURE TRANSPORT. THE SOUTH HALF OF THE CWA IS STILL NOT OUT OF THE WOODS EITHER...WITH SOME REMNANT CELLS/OUTFLOW STILL PROPAGATING NORTHEAST OUT OF NORTHERN INDIANA. HOWEVER...THINKING WILL REALLY NEED SOME LOCALLY ENHANCED CONVERGENCE/MOISTURE POOLING TO OVERCOME THE WARM MID LEVELS AND TAMPERED HEATING IN THE SOUTH DUE TO THE PERSISTENT CLOUDS MOST OF THE DAY. ANOTHER WARM NIGHT EXPECTED BASED ON CURRENT DEW POINTS AND 925 MB TEMPS FORECAST TO HOLD IN THE LOW TO MID 20S...RESULTING IN MINS IN THE LOW/MID 70S. LONG TERM...SUNDAY THROUGH SATURDAY PERSISTENT RIDGING ALOFT WILL CONTINUE INTO THE BEGINNING OF NEXT WEEK - ALLOWING THE SULTRY CONDITIONS TO PERSIST ACROSS THE REGION. SURFACE DEWPOINTS ARE EXPECTED TO SLOWLY INCH INTO THE LOW 70S ON THE HEALS OF CONTINUED LOW-LEVEL MOISTURE ADVECTION FROM THE SOUTHWEST. IF THE CONVECTION CAN HOLD OFF FOR MUCH OF DAY...TEMPS WILL CLIMB INTO THE LOWER 90S WITH HEAT INDICES IN THE UPPER 90S. GIVEN SUNDAY WILL BE WARMEST DAY OF THIS STRING AND IT IS THE THIRD CONSECUTIVE DAY OF HIGHER HEAT/HUMIDITY...A HEAT ADVISORY MAY BE WARRANTED. AGAIN...MUCH OF THIS HINGES ON THE LACK OF CONVECTION/DEBRIS DURING THE FIRST HALF OF THE DAY. MID-LEVEL WARM LAYER WILL LIKELY PERSIST ACROSS THE FORECAST AREA FOR A GOOD PART OF SUNDAY. THE LAYER OWING IT/S MAINTENANCE TO RIGHT EXIT INDUCED SUBSIDENCE AND ADVECTION OF A LATENT HEAT MODIFIED LAYER FROM THE ONGOING CONVECTION UPSTREAM OVER IOWA AND WISCONSIN. MAY HAVE TO DEAL WITH REMNANTS/DEBRIS OF THE UPSTREAM MCS EARLY IN THE DAY...THEN WAIT FOR THE BOUNDARY LAYER TO RECHARGE AS THE NEXT WEAK SHORTWAVE APPROACHES FROM THE SOUTHWEST. MODEL SOUNDINGS CONTINUE TO INDICATE THAT THE MID-LEVEL LAPSE RATES WILL BE MEDIOCRE...RESULTING IN MLCAPES CLIMBING TO ROUGHLY 1500J/KG. CERTAINLY ENOUGH TO SUPPORT SOME UPDRAFT VIGOR...BUT MAY BE LACKING MID-LEVEL ACCELERATION. HOWEVER...APPRECIABLE DEEP LAYER SHEAR WILL BE PRESENT...AIDING IN ORGANIZATION OF ANY NEW DEVELOPMENT. AS ALWAYS...THE DETAILS ALL HINGE ON THE EVOLUTION OF THE UPSTREAM CONVECTION. THE NEXT SPEED MAX...CURRENTLY OVER THE FOUR CORNERS REGION...WILL AFFECT THE REGION ON MONDAY AND WILL USHER IN SUBSTANTIAL HEIGHT FALLS. EXPECT ANOTHER ROUND OF CONVECTION...POTENTIALLY SEVERE...AS THE SURFACE COLD FRONT SWEEPS ACROSS THE REGION. THE GFS AND NAM ARE ADVERTISING A SURFACE WAVE TO RIPPLE ALONG THE BOUNDARY AS IT TRAVERSES THE REGION...WHICH SHOULD ENHANCE THE SHEAR PROFILE. AGAIN...THE CONVECTIVE DETAILS WILL HINGE UPON THE EVOLUTION OF SUNDAY/S ACTIVITY. REASONABLE AGREEMENT AMONG THE EXTENDED RANGE PROGS IN THE OVERALL EVOLUTION OF SYNOPTIC PATTERN FOR THE MIDDLE TO LATTER PORTIONS OF NEXT WEEK. HEIGHT AND THICKNESS FALLS ARE EXPECTED TUESDAY AND WEDNESDAY BEFORE THE UPPER-LEVEL RIDGE RECHARGES OVER THE CENTRAL AND NORTHERN PLAINS AND BUILDS BACK INTO THE LAKES REGION FOR WEEK/S END. FREQUENCY OF PRECIPITATION CHANCES WILL BE LOWER DURING THIS TIME STRETCH...ONLY EXPECTING A DECENT SHOT AT CONVECTION FRIDAY INTO SATURDAY AS A SURFACE FRONT ATTEMPTS TO MAKE A MOVE TOWARD THE REGION IN A SIMILAR FASHION AS YESTERDAY/S FRONT. THIS PATTERN WILL PROMOTE COOLER TEMPS DURING THE MID-WEEK TIME FRAME...BEFORE REBOUNDING ONCE AGAIN FROM THURSDAY ON AS THE RIDGE BUILDS OVERHEAD. MARINE... FAVORABLE BOATING CONDITIONS WILL CONTINUE...OUTSIDE OF THE CHANCE OF THUNDERSTORMS. WARM SOUTHERLY WINDS WILL PERSIST INTO MONDAY...WITH THE STABLE MARINE LAYER HOLDING WIND GUSTS BELOW 25 KNOTS...AND SUSTAINED WINDS GENERALLY 15 KNOTS OR LESS. SCATTERED THUNDERSTORMS REMAIN POSSIBLE IN THIS MOIST AND UNSTABLE AIRMASS...ESPECIALLY LATE MONDAY AS AN AREA OF LOW PRESSURE TRACKS THROUGH THE CENTRAL GREAT LAKES. WINDS WILL SHIFT TO THE NORTHWEST BEHIND THIS SYSTEM...WITH HIGH PRESSURE BUILDING INTO THE AREA ON TUESDAY. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE. LAKE ST CLAIR...NONE.
