NWS Detroit, MI wrote its last area forecast discussion before the first event at May 31, 10:43 AM EST, 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 1143 AM EDT MON MAY 31 2010 .UPDATE... CONVECTION THAT FIRED THIS MORNING ACROSS WESTERN LOWER MICHIGAN AND WITHIN VICINITY OF SAGINAW BAY HAS ALL BUT VANISHED DURING THE PAST HOUR. EXPECTATIONS ARE FOR THE STRATIFORM LEFTOVERS TO TRACK EASTWARD INTO LAKE HURON MOMENTARILY. THE NEXT BATCH OF CONVECTION IS AT THE DOORSTEP OF THE FAR SOUTHWESTERN CWA AND RESIDES ALONG A SECONDARY THETA E GRADIENT. THE MODELS HAVE STRUGGLED MIGHTILY WITH THIS COMPLEX...AS VARIOUS HI RES MODELS HAVE FAILED IN DEVELOPING THE NORTHERN INDIANA CONVECTION ALTOGETHER...IN ADDITION TO OPERATIONAL NWP WAITING UNTIL THE 12Z INITIALIZATIONS IN CAPTURING THE FRONTAL FEATURE. THEREFORE...THE NOWTERM (16-20Z) TIMEFRAME IS A CHALLENGE IN DETERMINING OVERALL CONVECTIVE TRENDS/COVERAGE. FOR NOW EXPECT THE CALHOUN/HILLSDALE CELLS TO LIFT NORTHEASTWARD ALONG THE LEAD EDGE OF DEEPER MOISTURE PUSH WHILE MAINTAINING SIMILAR BEHAVIOR/INTENSITY. LATER THIS AFTERNOON...THE MAIN MIDLEVEL CONVERGENCE ZONE AND COLD FRONT THAT IS LOCATED OVER NORTHERN LAKE MICHIGAN AND WISCONSIN WILL SLIDE EASTWARD. THERE IS INCREASED CONFIDENCE THAT WIDESPREAD CATEGORICAL SHOWERS AND THUNDERSTORMS WILL DEVELOP AND FILL ALONG THIS FEATURE AS IT SPREADS INTO LOWER MICHIGAN. THE AIRMASS ACROSS LOWER MICHIGAN IS MODERATELY UNSTABLE...WITH SBCAPES OF 2000-2500 J/KG. WIND SHEAR REMAINS WEAK TO MARGINAL UNDER NO CONSOLIDATED UPPER LEVEL JET CORE....BUT BULK SHEAR VALUES DO INCREASE TO AROUND 25 KNOTS LATE. GIVEN SOME CONVECTIVE VIGOR THAT HAS BEEN SPOTTED IN AREA RADARS THIS MORNING...AND THE DEGREE OF INSTABILITY...ISOLATED SEVERE REPORTS WILL BE POSSIBLE ALTHOUGH NOT EXPECTED TO BE WIDESPREAD. THE MAIN THREATS WITH CONVECTION TODAY WILL BE STRONG WINDS AND HEAVY RAINFALL. INHERITED HIGH TEMPERATURES SEEM REASONABLE AND A DECENT COMPROMISE. AREAS ACROSS THE NORTH SHOULD RECOVER THIS AFTERNOON IN ADVANCE OF THE APPROACHING COLD FRONT. && .PREV DISCUSSION...ISSUED 647 AM EDT MON MAY 31 2010 AVIATION... THUNDERSTORMS ARE RAPIDLY DEVELOPING ACROSS MICHIGAN AHEAD OF AN APPROACHING COLD FRONT. THIS DEVELOPMENT WILL CONTINUE AS THE DAY WEARS ON WITH WIDESPREAD SHOWERS AND THUNDERSTORMS EXPECTED AT THE TAF SITES MUCH OF TODAY. GIVEN THE RAPID DEVELOPMENT WILL INCLUDE ACTIVITY IN TEMPO GROUPS THIS MORNING...WITH PREVAILING DURING THE AFTERNOON WHEN THE CONVECTION BECOMES MORE WIDESPREAD. THE FRONT ITSELF IS FORECAST TO REACH MBS AROUND 16Z AND DTW AROUND 21Z. THE FRONT IS FORECAST TO BECOME NEARLY STATIONARY OVER THE DETROIT AREA THIS EVENING...WHICH MAY LEAD TO A PROLONGED PERIOD OF THUNDERSTORMS AT DTW/DET THROUGH THE NIGHTIME HOURS. FARTHER NORTH SHOWERS ARE EXPECTED AT THE OTHER TERMINALS THIS EVENING...WITH THE ACTIVITY WINDING DOWN AFTER MIDNIGHT. PREV DISCUSSION...ISSUED 410 AM EDT MON MAY 31 2010 SHORT TERM...TODAY AND TONIGHT THE DRY AND UNSEASONABLY WARM WEATHER WILL COME TO AN ABRUPT END TODAY AS A COLD FRONT MAKES ITS WAY THROUGH THE CENTRAL GREAT LAKES. BEFORE COOLER AIR MAKES ITS WAY INTO THE REGION ANOTHER DAY WITH HIGH TEMPERATURES WELL INTO THE 80S IS EXPECTED AHEAD OF THE APPROACHING COLD FRONT. DESPITE DEVELOPING STORMS BRINGING ABUNDANT CLOUDS TODAY...VERY WARM 850 MB TEMPERATURES OF +17 TO +18 COMBINED WITH MUCH WARMER MORNING TEMPERATURES THAN THE PREVIOUS FEW DAYS SHOULD ALLOW HIGHS TO REACH THE LOW TO MID 80S BEFORE CONVECTION ENDS THE INCOMING SOLAR RADIATION BY THE AFTERNOON HOURS AND THE RISE IN DAYTIME TEMPERATURES. THE NEXT ORDER OF BUSINESS IS RAIN CHANCES AS THE COLD FRONT MAKES ITS WAY THROUGH THE AREA TODAY. THE ONGOING CONVECTION ACROSS THE WESTERN GREAT LAKES ALONG THE FRONT MAKING ITS WAY EASTWARD CERTAINLY MAKES A STRONG CASE FOR CATEGORICAL POPS TODAY AS THE FRONT TAKES ADVANTAGE OF 1500 TO 2500 J/KG OF CAPE WITH THE AREA IN THE RIGHT REAR QUAD OF THE UPPER LEVEL JET AND MOISTURE POOLING AHEAD OF THE FRONT WITH DEW POINTS EXCEEDING 60 DEGREES. THE COLD FRONT LOOKS TO HALT ITS EASTWARD PROGRESSION BY LATE THIS AFTERNOON AND REMAIN ACROSS EXTREME SOUTHEAST MICHIGAN INTO THE EVENING HOURS. A SHORTWAVE MAKING ITS WAY NORTHEAST ALONG THE FRONT THIS EVENING WILL KEEP FAIRLY HIGH RAIN CHANCES IN THIS EVENING BEFORE THE BUILDING HIGH PRESSURE SYSTEM PUSHES THE FRONT TO THE EAST VERY LATE TONIGHT. THE SLOWER PROGRESSION OF THE FRONT WILL MEAN LIKELY POPS WILL CONTINUE MUCH THIS EVENING ACROSS THE AREA WITH CHANCY POPS WELL AFTER MIDNIGHT. FINALLY THE SEVERE WEATHER POTENTIAL WITH THE FRONT IS A CONCERN AS DAYTIME HEATING AND MOISTURE BRING TEMPS INTO THE LOW TO MID 80S WITH LOW TO MID 60 DEW POINTS ALLOWING SURFACE BASED CAPE VALUES TO REACH 1500 TO 2500 J/KG. DESPITE THE ABUNDANT INSTABILITY...SHEAR WILL BE VERY LACKING AS BUFKIT SOUNDINGS SHOW A VERY WEAK WIND FLOW WITH LESS THAN 50 KNOTS OF WIND SPEED ALL THE WAY UP TO 300 MB MEANING STORMS WILL NOT BE VERY WELL ORGANIZED AND HAVE A DIFFICULT TIME PRODUCING MUCH IN THE WAY OF WIND DAMAGE. IN ADDITION THE WET BULB ZERO HEIGHT ABOVE 10K FT WILL MEAN A MARGINAL HAIL THREAT...ESPECIALLY GIVEN THE LACK OF ORGANIZED STORMS WITH THE WEAK SHEAR IN PLACE. THE MAIN THREAT FROM THESE STORMS APPEARS TO BE HEAVY RAIN WITH LONG SKINNY CAPE PROFILES...WEAK SHEAR AND PRECIPITABLE WATER VALUES OF 1.5 TO 2 INCHES. THE MAIN THREAT WILL BE ALONG THE EASTERN CWA WITH THE STALLED OUT FRONT LATE THIS AFTERNOON AND THIS EVENING WHERE THE CHANCE FOR MULTIPLE ROUNDS OF RAIN WILL BE HIGHEST. FLASH FLOOD GUIDANCE VALUES HAVE REBOUNDED TO 2 TO 3 INCHES ACROSS THESE AREAS SO IT WILL TAKE MORE THAN ONE ROUND OF STORMS TO CAUSE FLOODING. THEREFORE WILL HOLD OFF ON ANY HYDRO HEADLINES AT THIS TIME. LONG TERM...TUESDAY THROUGH SUNDAY THE LONG TERM FORECAST WILL FEATURE A PROGRESSIVE PATTERN AS A NEARLY ZONAL FLOW BECOMES ESTABLISHED ACROSS THE NORTHERN TIER OF THE UNITED STATES. SHORTWAVE ENERGY MOVING THROUGH THE FLOW WILL BE THE DRIVING FACTOR BEHIND TIMING ROUNDS OF SHOWERS AND THUNDERSTORMS. MODELS HAVE LACKED CONSISTENCY IN THIS PATTERN OVER THE LAST SEVERAL DAYS LEADING TO UNCERTAINTY IN TIMING PRECIP CHANCES OVER THE COMING WEEK. EVEN HARDER TO DETERMINE WILL BE THE IMPACT THAT UPSTREAM CONVECTION WILL HAVE ON SHOWERS AND THUNDERSTORMS IN SOUTHEAST MICHIGAN. TUESDAY WILL BE A DRY DAY AS HIGH PRESSURE BUILDS OVER THE CENTRAL GREAT LAKES BRINGING A RETURN TO SUNNY SKIES. THE COLUMN UNDERGOES SUBSTANTIAL DRYING BY TUESDAY MORNING WITH ANY RESIDUAL BOUNDARY LAYER STRATUS MIXING OUT QUICKLY. MONDAYS WEAK COLD FRONT WILL ONLY HAVE A MINIMAL IMPACT ON TEMPERATURES...LIMITING HIGHS TO NEAR 80(UPPER 70S NEAR LAKE HURON) ON TUESDAY INSTEAD OF THE MID-UPPER 80S THAT WAS EXPERIENCED DURING MUCH OF THE PAST WEEK. HUMIDITIES WILL BE MUCH LOWER WITH DEWPOINTS DROPPING INTO THE UPPER 40S MAKING THE DROP IN TEMPERATURES FEEL GREATER. THE LINGERING UPPER LEVEL LOW OVER CANADA WILL PASS NORTH OF THE LAKES REGION FROM TUESDAY NIGHT INTO WEDNESDAY AS IT GETS ABSORBED INTO THE STRONGER UPPER LEVEL LOW DROPPING SOUTH ACROSS HUDSON BAY. A LOW PRESSURE SYSTEM WILL DEVELOP ALONG THE STALLED BAROCLINIC ZONE IN PLACE ACROSS WESTERN ONTARIO...WITH A TROUGH EXTENDING SOUTH TO LOW PRESSURE DEVELOPING OVER THE CENTRAL PLAINS. MODELS HAVE COME INTO BETTER AGREEMENT IN PULLING THIS FRONT SOUTH TO AROUND CENTRAL LOWER MICHIGAN BEFORE THE BOUNDARY STALLS BY MIDDAY WEDNESDAY. MEANWHILE MODELS DEPICT AN MCS ORIGINATING OVER IOWA ON TUESDAY NIGHT WHICH WILL BE A FEATURE TO WATCH AS IT TRACKS EASTWARD INTO SOUTHERN LOWER MICHIGAN/UPPER OHIO VALLEY AHEAD OF THE FRONT. HAVE INCREASED CHANCES OF THUNDERSTORMS TO ABOUT 50 PERCENT BUT DONT WANT TO GO ANY HIGHER AT THIS TIME AS THE MCS MAY FAVOR THE MORE UNSTABLE ENVIRONMENT TO OUR SOUTHWEST. BY THURSDAY THE 12Z/30 GFS AND 00Z/31 ECMWF ARE IN GOOD AGREEMENT IN ALLOWING THE WELL DEFINED PLAINS LOW TO TRACK EAST ALONG THE LINGERING FRONTAL BOUNDARY ACROSS THE TATE. MEANWHILE THE 00Z/31 GFS HAS SHIFTED THIS FEATURE SOUTH TO THE OHIO RIVER BUT SEEMS TO HAVE SIGNIFICANT CONVECTIVE FEEDBACK PROBLEMS SO WILL MAINTAIN THE CHANCE OF THUNDERSTORMS ON THURSDAY. THIS FEATURE FINALLY PULLS THE COLD FRONT THROUGH SOUTHEAST MICHIGAN BY THE END OF THE WEEK BRINGING NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES FOR NEXT WEEKEND. KEC MARINE... A COLD FRONT WILL MOVE THROUGH THE CENTRAL GREAT LAKES TODAY. THE COLD FRONT WILL BRING SHOWERS AND THUNDERSTORMS TODAY...WITH THE ACTIVITY DIEING DOWN FROM NORTH TO SOUTH TONIGHT. HIGH PRESSURE WILL BUILD BACK INTO THE REGION...BRINGING DRY WEATHER AND FAVORABLE BOATING CONDITIONS ON TUESDAY. ANOTHER LOW PRESSURE SYSTEM WILL BRING THE CHANCE FOR PRECIPITATION BACK TO THE CENTRAL GREAT LAKES WEDNESDAY AND THURSDAY. DESPITE THE MULTIPLE CHANCES FOR RAIN...WINDS AND WAVES DURING THE WEEK SHOULD BE BELOW SMALL CRAFT CRITERIA. && .DTX WATCHES/WARNINGS/ADVISORIES... MI...NONE. LAKE HURON...NONE.
