The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jun 24, 6:21 PM EST, 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 721 PM EDT WED JUN 24 2009 LATEST UPDATE...ALL BUT AVIATION... .SYNOPSIS...(330 PM EDT WED JUN 24 2009) A WEAK COLD FRONT WILL CROSS THE REGION ON THURSDAY. THUNDERSTORMS COULD FORM OUT AHEAD OF THE COLD FRONT LATER TONIGHT AND THURSDAY. DRY WEATHER WILL RETURN FOR FRIDAY AS A WEAK AREA OF HIGH PRESSURE BUILDS IN. HOWEVER MORE STORMS ARE POSSIBLE FOR SATURDAY INTO SATURDAY NIGHT. && .SHORT TERM...(330 PM EDT WED JUN 24 2009) (TONIGHT THROUGH FRIDAY NIGHT) THE MAIN CHALLENGE IN THE SHORT TERM DEALS WITH THE POTENTIAL FOR SEVERE THUNDERSTORMS AND HEAVY RAIN LATER TONIGHT INTO THURSDAY. THUNDERSTORMS WILL BE ON THE INCREASE AFTER MIDNIGHT AS AN UPPER LEVEL WAVE APPROACHES FROM THE WEST. FAVORABLE UPPER DIFFLUENCE ARRIVES BETWEEN 06Z AND 12Z...WITH WEAK CONVERGENCE IN THE LOW LEVELS. DEEP LAYER SHEAR INCREASES TO 40 KNOTS NEAR LDM BY 12Z. THE NAM SHOWS FAVORABLE ELEVATED INSTABILITY ARRIVING TOWARD DAYBREAK WITH CAPE VALUES OF MORE THAN 1000 J/KG. WE WILL NEED TO MONITOR THE SITUATION CLOSELY FOR POSSIBLE LATE NIGHT STRONG TO SEVERE STORMS. I DID FEATURE AN EARLIER ARRIVAL FOR POSSIBLE SEVERE IN MY ETEAMS MESSAGE AND WILL UPDATE THE HWO TO ACCOUNT FOR THAT. A LOT DEPENDS ON HOW THE CONVECTION UNFOLDS TONIGHT UPSTREAM. THIS ENVIRONMENT DOES FAVOR STORMS TO FORM OVERHEAD AS WELL. THE LOW LEVEL JET IS NOT STRONG...BUT CONVERGENCE LOOKS ENOUGH TO INITIATE STORMS. AS FOR THURSDAY THE NAM SHOWS THE UPPER DIFFLUENCE MOVING OFF EAST OF LAN BY 18Z...WHICH IS A LIMITING FACTOR. OTHERWISE DEEP LAYER SHEAR COMBINED WITH MODERATE INSTABILITY SUPPORTS ORGANIZED CONVECTION. THE BULK OF THE CONVECTION SHOULD BE OVER BY 6 PM AS THE MAIN AXIS OF LOW LEVEL CONVERGENCE SHIFTS SOUTHEAST OF JACKSON. GUIDANCE DOES KEEP SOME INSTABILITY INTO THE EVENING THOUGH. I DID NOT ADD THUNDERSTORMS TO THE FORECAST FOR FRIDAY...HOWEVER SOME INSTABILITY IS STARTING TO SHOW UP IN THE AFTERNOON. SOUNDINGS SUPPORT FREQUENT LIGHTNING AND LOCALLY HEAVY RAIN WITH ANY OF THE STORMS TONIGHT INTO THURSDAY. UNSEASONABLY WARM TEMPERATURES WILL PERSIST THROUGH FRIDAY NIGHT. && .LONG TERM...(330 PM EDT WED JUN 24 2009) (SATURDAY THROUGH TUESDAY NIGHT) UPPER RIDGE OVER THE CENTRAL CONUS WILL BEGIN TO BREAK DOWN BY THE START OF THIS WEEKEND. AS THE UPPER SYSTEM SITTING OFF OF THE CA COAST MOVES INLAND, A PIECE OF ITS ENERGY IS EJECTED NORTHEAST AROUND THE PERIPHERY OF THE UPPER RIDGE AND ACROSS THE DAKOTAS. A SECOND UPPER SYSTEM, SITTING OFF OF THE COAST OF NORTHWEST CONUS, WILL ALSO MOVE INLAND DURING THIS TIME. THIS UPPER SYSTEM WILL APPROACH MICHIGAN DURING THE WEEKEND. AT THE SURFACE, A COLD FRONT WILL BE SLIDING ACROSS LAKE MICHIGAN. TIMING WILL BE IMPORTANT AS THE FRONT WILL BE THE FOCUS FOR THUNDERSTORMS. AT PRESENT TIME, SHEAR AND TIMING OF UPPER LEVEL SHORTWAVE APPEAR TO FAVOR THE THREAT FOR STRONG TO SEVERE STORMS SATURDAY EVENING. WILL BUMP UP THE POPS DURING SATURDAY EVENING TIME FRAME TO ACCOUNT FOR INCREASING STORM THREAT. ONCE THE COLD FRONT AND ASSOCIATED UPPER SYSTEM SLIDES EAST SUNDAY, YET ANOTHER UPPER LOW SETTLES SOUTH FROM ONTARIO. COOLER TEMPERATURES WILL ACCOMPANY THIS SYSTEM. H85 TEMPERATURES IN THE SINGLE DIGITS NORTH TO LOW TEENS WILL REMAIN IN PLACE FOR THE START OF THE WORKWEEK. && .AVIATION...(721 PM EDT WED JUN 24 2009) SIMILAR TO LAST EVENING...IT APPEARS THAT ISOLATED THUNDERSTORMS WILL BE REMAINING WELL NORTH OF LANSING AND GRAND RAPIDS. THE RAIN SHOULD HOLD OFF UNTIL 10Z TO 12Z AS THE COLD FRONT MOVES IN WITH AREAS OF MVFR CONDITIONS WITH SHOWERS AND THUNDERSTORMS MUCH OF THE MORNING INTO THE AFTERNOON AS IS SLOWLY SAGS SOUTH ACROSS LOWER MICHIGAN. SOME ISOLATED IFR POSSIBLE WITH HEAVIER STORMS BUT TIMING ON THESE CANNOT BE PINNED DOWN AT THIS TIME....MOST LIKELY BETWEEN 16Z TO 20Z. && .MARINE...(330 PM EDT WED JUN 24 2009) LIGHT WINDS WILL REMAIN IN PLACE THROUGH FRIDAY RESULTING IN WAVES OF A 2 FEET OR LESS. HOWEVER IN ANY THUNDERSTORMS...WINDS AND WAVES COULD BE HIGHER. && .HYDROLOGY...(330 PM EDT WED JUN 24 2009) HEAVY RAIN IS POSSIBLE TONIGHT AND THURSDAY AS SLOW MOVING THUNDERSTORMS DEVELOP AHEAD OF A COLD FRONT. QPF AROUND AN INCH IS POSSIBLE WHICH WILL CAUSE AREA RIVERS AND STREAMS TO RISE AGAIN. THE MOST LIKELY TIMEFRAME FOR THUNDERSTORM IS FROM AFTER MIDNIGHT TONIGHT UNTIL 6 PM THU. AN INCH OF RAIN COULD FALL IN LESS THAN AN HOUR WITH THE STRONGER STORMS. LOCALLY IN EXCESS OF 2 INCHES OF RAIN COULD FALL. RIGHT NOW THE MOST LIKELY LOCATION FOR THAT TO HAPPEN IS NORTH OF A MUSKEGON TO ALMA LINE. THIS COULD LEAD TO URBAN AND POOR DRAINAGE FLOODING. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...NONE.
