NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jun 7, 9:25 AM EST, 1 hour 45 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED... NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1025 AM EDT THU JUN 7 2007 .UPDATED... I HAVE ISSUED A HIGH WIND ADVISORY FOR ALL OF SOUTHWEST LOWER MICHIGAN UNTIL 8 AM FRIDAY. THIS IS MORE FOR DAMAGE TO LEAFED OUT TREES THAN BECAUSE I EXPECT WIDESPREAD GUSTS BETWEEN 45 AND 58 MPH. TAMDAR DOES SHOW 56 KNOTS AT GRR NEAR 4000 FT AT 8 AM THIS MORNING. SO THERE IS A FAIR AMOUNT OF WIND...CLOSE TO THE SURFACE TO MIX DOWN. I SUSPECT THE GUSTY WINDS WILL REMAIN POSSIBLE UNTIL AFTER THE SQUALL LINE MOVES THROUGH AFTER MIDNIGHT. OTHER THAN ISSUING THE WIND ADVISORY THE OVERALL FORECAST LOOKS FINE. I DO NOT PLAN TO CHANGE MUCH ELSE AT THIS POINT. THE SPC 836 AM UPDATE TO THEIR DAY ONE FORECAST KEEPS THE MODERATE RISK FOR SEVERE STORMS OVER THE WESTERN SECTIONS OF LOWER MICHIGAN THROUGH 8 AM FRIDAY. THE LATEST NAM SHOWS ABOUT THE SAME SCENARIO...THE SQUALL LINE WILL COME INTO THE LAKE SHORE AREAS NEAR MIDNIGHT. THE SHEAR REMAINS STRONG AND THERE IS DECENT MIXED LAYER CAPE AS THE STORMS MOVE ONSHORE... NEAR 1000 J/KG. .PREVIOUS DISCUSSION... OUR PRIMARY SHORT TERM FCST CONCERN IS TO EVALUATE OUR SVR WX POTENTIAL FOR LATE TONIGHT. THE SPC HAS ALREADY PLACED MUCH OF OUR CWFA IN A MDT RISK AREA FOR SVR CONVECTION LATE TONIGHT WITH A SLGT RISK FOR THE REMAINDER OF OUR CWFA. IR SAT TRENDS AND MODEL TIME HEIGHT RH PROGS SUGGEST SKIES WILL BE PARTLY SUNNY TODAY. IT WILL BECOME WINDY PARTICULARLY THIS AFTERNOON WHEN DEEPER MIXING WILL OCCUR WITH SOUTH WINDS SUSTAINED AT 15 TO 25 MPH AND GUSTS TO AROUND 40 MPH. A WIND ADVISORY WAS STRONGLY CONSIDERED. IN THE END WE FELT THAT GUSTS THIS AFTERNOON WILL FALL JUST SHORT OF 45 MPH ADVISORY CRITERIA. WE ALSO BELIEVE MAX TEMPS WILL FALL JUST A DEGREE OR TWO SHORT OF THE 90 DEGREE MARK GIVEN QUITE A BIT OF CLOUD COVER STREAMING IN FROM THE WEST. WE ALSO NOTICED THAT MOST LOCATIONS WELL TO OUR SW YESTERDAY IN THE WARM SECTOR MAXED OUT IN THE UPPER 80S RATHER THAN LOWER 90S. STRONG TO SEVERE STORMS ARE LIKELY ACROSS OUR CWFA LATE TONIGHT (MAINLY AFTER MIDNIGHT). WIND DAMAGE WILL BE THE PRIMARY SVR WX THREAT. WIND SPEEDS WITH HEIGHT WILL BE VERY IMPRESSIVE BY 12Z FRI (35-40 KTS 2 KFT AGL... 50-70 KTS 10 KFT AGL... 80 KTS 15-20 KFT AGL AND A 300 MB JET OF AROUND 100 KTS). THERE IS DEFINITELY POTENTIAL FOR BOWS AND MINI BOWS IN ADDITION TO LEWP RADAR SIGNATURES. MANY FACTORS ALSO APPEAR POTENTIALLY FAVORABLE FOR A SERIAL (DYNAMICALLY DRIVEN) DERECHO EVENT BETWEEN AROUND 05Z AND 12Z. FURTHERMORE... A HIGH 0-6 KM BULK SHEAR ENVIRONMENT IS THE KEY TO ANTICIPATING SUPERCELLS. THESE SHEAR VALUES ARE PROGGED TO BE VERY HIGH LATE TONIGHT. THEREFORE I SUSPECT THAT THERE COULD BE SOME SUPERCELLS EMBEDDED WITHIN AND OUT AHEAD OF THE SQUALL LINE. OBVIOUSLY TORNADOES CANNOT BE RULED OUT IN THIS TYPE OF ENVIRONMENT CONDUCIVE TO SUPERCELL FORMATION. WE ALSO NOTICED THAT LCL HEIGHTS WILL GRADUALLY LOWER TONIGHT AS THE INFLUX OF RICHER LOW LEVEL MOISTURE JUST AHEAD OF THE FRONT OCCURS. THE BOTTOM LINE IS WE WILL NEED TO MONITOR THIS SITUATION VERY CLOSELY TODAY THROUGH TONIGHT SINCE A SIGNIFICANT SEVERE WX EVENT IS CERTAINLY POSSIBLE. SEVERAL FACTORS GOING AGAINST SVR WX POTENTIAL TONIGHT INCLUDE COLD FRONTAL TIMING AND TIMING OF CONVECTION INTO OUR CWFA AT A DIURNALLY UNFAVORABLE TIME OF DAY FOR SVR WX. SFC BASED CONVECTION ALSO HISTORICALLY STRUGGLES TO CROSS VERY COLD LAKE MI WATERS AT THIS TIME OF YEAR AND TYPICALLY DIMINISHES SIGNIFICANTLY AS TSTORM INFLOW AND UPDRAFTS INGEST THE RELATIVELY COLD MARINE AIR. WE HAVE SEEN THIS HAPPEN TIME AND TIME AGAIN THIS TIME OF YEAR WHEN CONVECTION IS SFC BASED RATHER THAN ELEVATED. THE SVR WX THREAT WOULD ALSO BE GREATER IF THE SFC LOW WERE TRACKING FURTHER SE IN CLOSER PROXIMITY TO LWR MI. FINALLY WE BELIEVE THAT VIGOROUS CONVECTIVE DEVELOPMENT AFTER 04Z-06Z MAY TEND TO GRAVITATE FURTHER SW OF OUR CWFA IN AN AXIS OF MUCH GREATER SFC BASED INSTABILITY FROM ORD SW TO STL AND OKC. NEVERTHELESS... ALL THINGS CONSIDERED... STRONG TO SEVERE CONVECTION STILL APPEARS LIKELY BETWEEN 05Z AND 12Z WITH WIND DAMAGE BEING THE PRIMARY SEVERE WX THREAT. EVEN A GRADUALLY DIMINISHING LINE OF SFC BASED CONVECTION CROSSING LAKE MI WOULD STILL HAVE POTENTIAL TO PRODUCE WIND DAMAGE GIVEN MAGNITUDE OF WIND SPEEDS W/HEIGHT AND SPEED SHEAR. LINGERING MORNING RAIN AND CONVECTION FRIDAY PRIMARILY OVER EASTERN AND SOUTHERN CWA WILL GRADUALLY TAPER OFF. THE FRONT SHOULD ALREADY BE NEAR DTW BY 18Z FRIDAY SO I SUSPECT CONVECTIVE REDEVELOPMENT WILL FIRE JUST SE OF OUR CWA FRIDAY AFTERNOON. WE WILL NEED TO MONITOR THIS CLOSELY LATE FRIDAY MORNING AND EARLY FRIDAY AFTERNOON THOUGH... SINCE IT COULD BE A CLOSE CALL FOR OUR EASTERN CWA ESPECIALLY IF THE FRONT SLOWS JUST A BIT. SKIES WILL CLEAR BEHIND THE FRONT FRIDAY NIGHT FOLLOWED BY MOSTLY CLEAR SKIES WITH SEASONABLE TEMPS SATURDAY. .LONG TERM... SURFACE HIGH PRESSURE PREVAILS IN THE SUNDAY THROUGH WEDNESDAY PERIOD...WITH THE UPPER FLOW PATTERN TRANSITIONING FROM ZONAL THIS WEEKEND TO A HIGH AMPLITUDE RIDGE BY TUESDAY. EXPECT A STRETCH OF MAINLY SUNNY AND WARM/SUMMER-LIKE WEATHER WITH TEMPERATURES SLOWLY MODERATING FROM NEAR CLIMO OVER THE COMING WEEKEND TO ABOVE CLIMO BY MIDWEEK. SUPPOSE A COUPLE OF ISOLATED DIURNAL/AIR MASS TSTMS ARE NOT OUT OF THE QUESTION NEXT WEEK AS DEW POINTS INCH UP... PARTICULARLY ALONG THE LAKE BREEZE FRONT...BUT NOT WORTH MENTIONING AT THIS POINT. && .GRR WATCHES/WARNINGS/ADVISORIES...SMALL CRAFT ADVISORY ENTIRE NEAR SHORE THROUGH 12Z FRIDAY. WIND ADVISORY FOR THE ENTIRE CWA THROUGH 8 AM FRIDAY. && LAURENS MEADE WDM

THE MAIN THREAT TONIGHT IS DAMAGING STRAIGHT LINE THUNDERSTORM WINDS IN EXCESS OF 60 MPH... BUT LARGE HAIL IS ALSO POSSIBLE. ISOLATED TORNADOES CANNOT BE RULED OUT EITHER. A SQUALL LINE IS EXPECTED TO DEVELOP OVER WISCONSIN LATE THIS AFTERNOON AND EVENING AHEAD OF AN APPROACHING COLD FRONT... THEN RACE RAPIDLY EAST AT 50 MPH ACROSS LAKE MICHIGAN. THE SQUALL LINE SHOULD REACH THE LAKE MICHIGAN SHORELINE NORTH OF HOLLAND AROUND MIDNIGHT...AND A KALAMAZOO TO ALMA LINE BY ABOUT 3 AM. THE STORMS MAY TEND TO WEAKEN A BIT AS THEY MOVE FARTHER EAST...BUT COULD STILL CONTAIN DAMAGING WIND GUSTS AND HAIL. SOUTH WINDS WILL GUST AS HIGH AS 50 MPH THIS AFTERNOON AND TONIGHT AS A STRONG STORM MOVES NORTHEAST THROUGH MINNESOTA INTO SOUTHERN CANADA. THE GUSTY WINDS WILL DIMINISH AFTER THE SQUALL LINE...AHEAD OF THE COLD FRONT MOVES ACROSS THE AREA AFTER MIDNIGHT. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY A SLIGHT RISK OF SEVERE WEATHER EXISTS FRIDAY EAST OF A LINE FROM BATTLE CREEK TO LANSING... BEFORE THE COLD FRONT CLEARS THE AREA. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL LIKELY BE NEEDED TONIGHT... AND POSSIBLY FRIDAY FOR AREAS EAST OF BATTLE CREEK AND LANSING.

IT SHOULD REACH THE LAKE MICHIGAN SHORELINE NORTH OF HOLLAND AROUND MIDNIGHT...AND SOUTH OF HOLLAND BY 2 AM. SOUTH WINDS TO 30 KNOTS WILL CREATE WAVES OF 4 TO 7 FEET NORTH OF WHITEHALL TODAY AND TONIGHT...AND 3 TO 6 FEET SOUTH OF WHITEHALL. THIS WILL POSE A THREAT TO SMALL CRAFT AS WELL AS ANYONE SWIMMING AT AREA BEACHES OR VENTURING OUT ON PIERS. RIP CURRENTS WILL BE POSSIBLE...MAINLY NEAR PIERS SINCE THE WIND WILL BE NEARLY PARALLEL TO THE SHORE. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY WAVES AROUND 4 FEET AND DANGEROUS RIP CURRENTS ARE LIKELY ON FRIDAY DUE TO STRONG WEST WINDS BEHIND THE COLD FRONT. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL LIKELY BE NEEDED TONIGHT. MEADE WDM
