NWS Detroit, MI wrote its last area forecast discussion before the first event at May 31, 11:47 AM EST, 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 1247 PM EDT FRI MAY 31 2013 .AVIATION... //DISCUSSION... PREFRONTAL TROUGH/MOISTURE AXIS TRIGGERING SHOWERS AND EMBEDDED THUNDERSTORMS WILL BE SLIDING EAST OF THE AREA BY MID AFTERNOON. THUS CONVECTIVE THREAT WILL THEN BE LOW (AFTER 20Z) THROUGH THE REMAINDER OF THE DAY. WILL BE WAITING ON MORE ORGANIZED ACTIVITY OVER THE WESTERN OHIO VALLEY TO ADVANCE INTO SOUTHERN LOWER MICHIGAN THIS EVENING/TONIGHT...BUT TIMING IS PROBLEMATIC...AS STRONG MID LEVEL JET COULD PROMOTE A RAPID INCREASE IN FORWARD SPEED TO THE EAST. BEST ESTIMATE THIS FAR OUT IS FOR STORMS TO MOVE THROUGH DURING THE EVENING HOURS...WITH ANOTHER LULL BEFORE ANOTHER BATCH ARRIVES SATURDAY MORNING. OUTSIDE OF THUNDERSTORMS...THE OTHER AVIATION ISSUE COULD BE OVERNIGHT TONIGHT. IF BATCH OF STORMS MOVES THROUGH DURING THE EVENING HOURS...LEFTOVER LOW LEVEL MOISTURE COULD PRODUCE MVFR/IFR CEILINGS AND EVEN SOME PATCHY FOG AS SURFACE WINDS LOOK TO BE WEAK. //DTW THRESHOLD THREATS... * MEDIUM CONFIDENCE IN THUNDERSTORMS...18-19Z...THEN AGAIN THIS EVENING. LOW CONFIDENCE OVERNIGHT INTO TOMORROW. * LOW CONFIDENCE IN CEILINGS BELOW 5000 FEET THIS AFTERNOON AND EVENING...MEDIUM CONFIDENCE OVERNIGHT...LOW CONFIDENCE TOMORROW. && .PREV DISCUSSION...ISSUED 912 AM EDT FRI MAY 31 2013 UPDATE... THE FORECAST LOOKS ON TRACK AS BATCH OF SHOWERS OVER INDIANA/WESTERN LOWER MICHIGAN TIED TO SHORTWAVE TRACKING NORTH THROUGH THE WESTERN GREAT LAKES AND REMNANT 850 JET WEAKENS AND FALL APART. HOWEVER...MORNING SUNSHINE IS QUICKLY DESTABILIZING SOUTHEAST MICHIGAN...WITH MLCAPES ON THERE WAY TO 2000 J/KG AS WE RISE INTO THE LOWER 80S TOWARD THE NOON HOUR. 12Z DTX SOUNDING REVEALED AN 850 MB DEW PT OF 12 C...WHICH IS GOOD...BUT 850 MB THETA-E AXIS IS EXPECTED TO BE MOVING THROUGH 15-18Z WITH DRYING OCCURRING DURING THE LATE AFTERNOON HOURS (UNLIKE YESTERDAY). THIS MAKES FOR A DIFFICULT FORECAST WITH RESULT TO AREAL COVERAGE AS SURFACE BASED STORMS SHOULD INITIATE ON THIS DIFFERENTIAL HEATING BOUNDARY. THUS...CAN'T ARGUE WITH SCATTERED 50 POP AT THIS POINT UNTIL TRENDS SUPPORT OTHERWISE. CHANCE OF SEVERE STORMS REMAINS VALID WITH 0-6 KM WIND SHEAR OF 40 KNOTS AS PREVIOUSLY NOTED. PREV DISCUSSION...ISSUED 423 AM EDT FRI MAY 31 2013 SHORT TERM...TODAY AND TONIGHT THUNDERSTORMS HAVE CONTINUED TO FIRE OVER WESTERN LOWER MICHIGAN THIS MORNING AS A NOCTURNAL LOW LEVEL JET HAS WORKED INTO THE STATE...AND ALSO AS A SMALL UPPER SHORTWAVE LIFTS UP THROUGH INDIANA. CONVECTIVE ACTIVITY DOES HAVE A SLIGHT EASTERLY COMPONENT TO IT...AND IS EXPECTED TO CLIP THE SAGINAW VALLEY AROUND SUNRISE. THE REMAINDER OF THE AREA LOOKS TO REMAIN FAIRLY DRY THROUGH THE EARLY PART OF THE MORNING...BUT DID KEEP SOME LOW POPS IN THE FORECAST WITH GOOD ELEVATED INSTABILITY SHOWN ON 00Z KDTX SOUNDING FROM LAST EVENING...AS WELL AS FORECAST SOUNDINGS FOR THIS MORNING...AND THE PRESENCE OF THE LOW LEVEL JET. VERTICALLY STACKED UPPER AND SURFACE LOW PRESSURE WILL SLOWLY MOVE FROM THE NORTHERN PLAINS INTO THE UPPER MIDWEST TODAY. THIS WILL CONTINUE TO FEED WARM MOIST AIR INTO MICHIGAN (PW VALUES STAY AT OR ABOVE 1.5 INCHES) WHILE ALSO KEEPING US VULNERABLE TO MVC'S FROM UPSTREAM CONVECTION STRETCHING DOWN THROUGH ARKANSAS. GEM/GFS DO IN FACT GENERATE AN MCV OUT OF CURRENT CONVECTION OVER ARKANSAS (NAM IS NOT HANDLING THAT WELL) AND TRACK IT UP INTO SOUTHEAST MICHIGAN AROUND 18Z. THIS COULD BE A TRIGGER FOR CONVECTION OVER THE AREA...IN ADDITION TO DAYTIME HEATING AND OUTFLOW BOUNDARIES. MAIN QUESTION AS USUAL WILL BE HOW MUCH INSTABILITY WILL BUILD PRIOR TO THUNDERSTORM DEVELOPMENT. WILL START THE DAY FAIRLY CLEAR ACROSS THE EASTERN 2/3 OF THE FORECAST AREA...BUT DO EXPECT SOME HIGHER CLOUD DEBRIS TO SPILL IN LATER FROM OFF CONVECTIVE COMPLEXES OVER MISSOURI AND IOWA. MODEL GUIDANCE SUPPORTS BETWEEN 1000-2000 J/KG OF CAPE BUILDING BY AFTERNOON ACROSS SOUTHEAST MICHIGAN (ASSUMING HIGHS CLIMB INTO THE LOW 80S)...AS THE GROUND HEATS AND INSTABILITY BECOMES SURFACE BASED. THIS INSTABILITY COMBINED WITH 30-40 KNOTS OF 6KM BULK SHEAR WILL SUPPORT THE THREAT FOR SEVERE WEATHER TODAY. STRONG UPDRAFTS WILL SUPPORT LARGE HAIL WHILE PRETTY MUCH UNIDIRECTIONAL SHEAR ABOVE 1KM AND DRIER AIR IN THE LOWER LEVELS WILL SUPPORT MORE OF A DAMAGING WIND THREAT (WITH LINEAR FEATURES EXPECTED TO DEVELOP). CANNOT RULE OUT SUPERCELLS AND EVEN A TORNADO HOWEVER GIVEN SOME UNIDIRECTIONAL SHEAR IN THE LOWEST 1KM. VERY HEAVY RAINFALL WILL ALSO BE LIKELY WITH EACH STORM THAT DEVELOPS GIVEN HIGH PW VALUES. MAY SEE A LULL IN ACTIVITY LATER THIS EVENING WITH THE LOSS OF DAYTIME HEATING. WOULD THEN EXPECT ACTIVITY TO FLARE UP AGAIN OVERNIGHT WITH RE-DEVELOPMENT OF A NOCTURNAL LOW-LEVEL JET...THIS TIME SLIGHTLY FURTHER EAST AS THE LOW TO OUR WEST MOVES CLOSER. WILL ALSO SEE STRONGER HEIGHTS FALLS LATE AND STRONG UPPER DIFFLUENCE ALSO LOOKS TO BECOME MORE CENTERED OVER THE AREA AS AN UPPER JETLET APPROACHES. HAVE CONTINUED TO CARRY LIKELY POPS FOR THE SECOND HALF OF THE NIGHT. LONG TERM... SATURDAY THROUGH THURSDAY TEXTBOOK CONSOLIDATION OF THE UPPER JET ON THE DOWNSTREAM SIDE OF THE PLAINS UPPER LOW WILL LEAD TO AN OPENING OF THE CIRCULATION BY SATURDAY MORNING. THE TIMING OF THIS PROCESS HAS BEEN AN ISSUE IN THE FORECAST OVER THE LAST FEW CYCLES AND REMAINS SOMEWHAT PROBLEMATIC, BUT WITH SOME CONVERGENCE OF MODEL SOLUTIONS NOTED IN THIS PACKAGE. THE NAM HAS MADE THE LARGEST ADJUSTMENT ON A SLOWER/WESTWARD POSITION OF THE 500 MB TROUGH AXIS BY 12Z SATURDAY AS IT GAINED A BETTER FEEL FOR INCOMING SHORT WAVE ENERGY FROM THE PACIFIC AND A CORRESPONDING RIDGE BUILDING OVER THE ROCKIES. THE POSITION OF THE UPPER JET OVER WISCONSIN AND UPPER MICHIGAN WILL THEN BE FAVORABLE FOR MAINTENANCE OF THE LOW LEVEL JET AND A LARGER SCALE AGEOSTROPHIC CIRCULATION FROM THE LOW LEVEL THETA-E RIDGE WESTWARD INTO THE FRONTAL ZONE. THIS FORCING WILL MAINTAIN A GENEROUS COVERAGE OF SHOWERS AND THUNDERSTORMS DURING SATURDAY MORNING, MUCH LIKE ACTIVITY ONGOING EARLY THIS MORNING ONLY FARTHER EAST, AND IN AN ENVIRONMENT OF ELEVATED INSTABILITY MARKED BY 850 LI AROUND -2C AND 700-500 MB LAPSE RATES NEAR 7C. THE 00Z MODELS THEN BRING A SURGE OF MOISTURE UP FROM THE MID MISSISSIPPI VALLEY DURING THE AFTERNOON, WHICH LOOKS REASONABLE GIVEN THE EXTRA SUPPORT FOR A WAVE OF LOW PRESSURE UNDER THE ENTRANCE REGION OF THE JET AXIS. THE MAIN QUESTION BY THEN WILL BE WITH SEVERE WEATHER POTENTIAL AND HOW MUCH, IF ANY, RECOVERY OF SURFACE BASED INSTABILITY CAN BE REALIZED AS THE COLD FRONT MOVES THROUGH SE MICHIGAN DURING SATURDAY EVENING. THE NORMALLY BULLISH NAM ACTUALLY DROPS SURFACE BASED CAPE BELOW 1000 J/KG BY LATE IN THE DAY UNDER NEARLY MOIST ADIABATIC LAPSE RATES THROUGH THE MID LEVELS. HOWEVER, SHOULD THIS NOT BE THE CASE AND ADEQUATE RECOVERY BECOMES POSSIBLE, THEN CONVECTION WILL BE ABLE TO FULLY UTILIZE A FAVORABLE WIND FIELD FOR ORGANIZED STORMS. BULK SHEAR IN THE 0-6 KM LAYER IS SHOWN TO REACH A UNIDIRECTIONAL 30-40 KNOTS IN MODEL SOUNDINGS WITH A 45 KNOT 500 MB WIND SPEED, GOOD ENOUGH FOR MULTICELL GROWTH INTO LINE SEGMENTS WITH DAMAGING WIND POTENTIAL. WHILE THE DEGREE OF INSTABILITY WILL BRING SEVERE WEATHER POTENTIAL INTO QUESTION DURING THE PEAK OF THE DIURNAL CYCLE, LIKELY POPS IN THE GOING FORECAST LOOK VERY MUCH ON TARGET SATURDAY MORNING WITH THE PASSAGE OF THE COLD FRONT WORTH ENTRY LEVEL CATEGORICAL POPS HEADING INTO SATURDAY EVENING. LOCALLY HEAVY RAINFALL AND THE POTENTIAL FOR FLOODING WILL ALSO CONTINUE TO BE A HIGHLIGHT IN THE HWO AS THIS WILL BE THE LATEST OF SEVERAL ROUNDS OF CONVECTION OVER THE LAST FEW DAYS BUT LIKELY THE MOST WIDESPREAD GIVEN THE FRONTAL BOUNDARY AS A FOCUS. MODEL FORECAST SOUNDINGS INDICATE STEEPER LAPSE RATES BELOW 700 MB DURING SUNDAY DUE TO COOLER AIR MOVING IN POST FRONT. EXPECT THIS WILL MAINTAIN A MORE PESSIMISTIC SKY COVER AND EVEN AN ISOLATED SHOWER DURING PEAK HEATING. THIS WAS THE ONLY ADJUSTMENT IN THE LONGER RANGES OF THE FORECAST AS SURFACE HIGH PRESSURE IS EXPECTED TO BE IN FULL CONTROL AND EXERTING DRY CONDITIONS OVER THE GREAT LAKES BY MONDAY. MAX TEMPS GENERALLY IN THE MID 60S WILL BE ABOUT 10 DEGREES BELOW NORMAL FOR THE FIRST WEEK OF JUNE. MARINE... SOUTHERLY WINDS WILL REMAIN BELOW 20 KNOTS THROUGH SATURDAY NIGHT AS A LOW PRESSURE SYSTEM VERY SLOWLY APPROACHES FROM THE PLAINS. A WARM AND UNSTABLE AIRMASS WILL REMAIN IN PLACE IN ADVANCE OF THIS SYSTEM...AND CONTINUE TO SUPPORT CHANCES FOR THUNDERSTORMS. SOME OF THESE STORMS MAY BECOME SEVERE TODAY THROUGH SATURDAY. THE COLD FRONT WILL TRACK THROUGH THE AREA EARLY ON SUNDAY...BRINGING MORE CHANCES FOR SHOWERS AND THUNDERSTORMS AND FLIPPING WINDS TO THE NORTHWEST. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE.
