NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Sep 16, 1:00 PM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 200 PM EDT THU SEP 16 2010 LATEST UPDATE...AVIATION.. .SYNOPSIS...(400 AM EDT THU SEP 16 2010) A LOW PRESSURE SYSTEM WILL TRACK EAST ACROSS SOUTH CENTRAL LOWER MICHIGAN THIS MORNING BRINGING RAIN AND SOME THUNDERSTORMS. SHOWERS WILL TAPER OFF MID TO LATE THIS AFTERNOON AND IT WILL TURN BREEZY IN THE AFTERNOON ON THE BACK SIDE OF THIS SYSTEM. DRY WEATHER IS ON TAP TONIGHT THROUGH FRIDAY AFTERNOON FOLLOWED BY A CHANCE OF SHOWERS FRIDAY NIGHT AND SATURDAY. SEASONABLE TEMPERATURES ARE ANTICIPATED THROUGH MONDAY. && .SHORT TERM...(1051 AM EDT THU SEP 16 2010) (REST OF TODAY THROUGH SATURDAY AFTERNOON) I UPDATED THE GRIDS TO SHOW THE HIGHEST CHANCE FOR CONVECTION WILL BE SOUTH OF INTERSTATE 96 THIS AFTERNOON. AT 10 AM THERE WAS AN AREA OF THUNDERSTORMS OVER WESTERN LAKE MICHIGAN...JUST EAST OF MILWAUKEE TO CHICAGO...MOVING EAST AROUND 25 KNOTS. THAT IS ON THE COLD FRONT BUT MORE IMPORTANTLY IT IS UNDER A DECENT LOOKING MID LEVEL SHORTWAVE AND PV MAX THAT ON THE WATER VAPOR LOOPS WAS JUST SOUTHWEST OF MILWAUKEE AT 10 AM. THIS IS FORECAST TO MOVE DUE EAST ACROSS THE SOUTHERN GRR CWA THIS AFTERNOON. GIVEN THE MODEL FORECAST -5 SURFACE BASED LI AND THE DYNAMICS FROM THE SHORTWAVE/PV MAX IT WOULD SEEM THE COMPLEX SHOULD CONTINUE TO MOVE EAST WITHOUT DISSIPATING. THUS I HAVE LIKELY POP NEAR AND SOUTH OF INTERSTATE 96 THIS AFTERNOON FOR THAT COMPLEX TO MOVE EAST. IT SHOULD GET TO THE AZO AREA BY 1 PM AND JXN BY 4 PM. ELSEWHERE JUST A FEW SHOWERS THIS AFTERNOON WITH MOSTLY CLOUDY SKIES. WINDS WILL GET GUSTY... MORE OF THE SOUTHERN 1/2 OF THE CWA MID TO LATE AFTERNOON AS THE SYSTEM MOVES OUT. MID LEVEL CLOUDS SHOULD CLEAR EARLY TONIGHT BUT THAT WILL ALLOW EXTENSIVE FOG AND LOW CLOUDS TO DEVELOP OVERNIGHT. WINDS WILL QUICKLY DECREASE AFTER MIDNIGHT WHICH WILL FACILITATE FOG DEVELOPMENT. ONLY ISSUE IS IF THERE IS TO MUCH LOW CLOUDS AROUND THE FOG WILL BE LESS OF AN ISSUE. THE NEXT FRONTAL SYSTEM WILL BRING THE CHANCE OF SHOWERS FRIDAY NIGHT INTO SATURDAY. THERE IS SOME SUGGESTION OF MID LEVEL INSTABILITY SATURDAY... I MAY HAVE TO PUT THE RISK OF THUNDERSTORMS IN FORECAST FOR SATURDAY WITH THE NEW ZONE PACKAGE AT 4 PM. && .LONG TERM...(400 AM EDT THU SEP 16 2010) (SATURDAY NIGHT THROUGH WEDNESDAY) THE MAIN CHALLENGE IN THE LONG TERM DEALS WITH THE RISK FOR THUNDERSTORMS SUN NIGHT INTO MONDAY. THE GFS IS SUGGESTING A POTENTIAL FOR SHOWERS AND THUNDERSTORMS AS A WARM FRONT LIFTS INTO SOUTHWEST LOWER MICHIGAN SUNDAY NIGHT. ELEVATED INSTABILITY ARRIVES AND A LOW LEVEL JET IS SEEN IN WI. ALL THIS SUPPORTS A CHANCE FOR SHOWERS AND THUNDERSTORMS. THE NEW HIGH RES EURO CAME IN AND STILL MAINTAINS A DRY PERIOD SUN NIGHT INTO MON...FOCUSING THE LOW LEVEL JET MUCH FURTHER WEST INTO SD AND MN. GIVEN THE UNCERTAINTY...WILL KEEP THE CURRENT DRY FORECAST GOING FOR SUN NIGHT INTO MON. && .AVIATION...(200 PM EDT THU SEP 16 2010) RAIN/STORMS WILL BE ENDING SHORTLY AS LOW PRESSURE MOVES EAST. ALREADY THERE HAS BEEN SOME CLEARING ACROSS NORTHWEST LWR. CLOUDS IN WISCONSIN ARE TAKING ON A CELLULAR LOOK SUGGESTING WE MAY BREAK OUT FOR A FEW HOURS THIS EVENING. THAT TREND IS REFLECTED IN THE TAFS. BUT GIVEN THE RAINFALL TODAY...ANY CLEARING COUPLED WITH LIGHT WINDS TONIGHT SHOULD RESULT IN CLOUDS QUICKLY REDEVELOPING ALONG WITH FOG. LOOK FOR IFR/LIFR OVERNIGHT BEFORE IMPROVING CONDITIONS AFTER 12Z FRIDAY. && .MARINE...(1051 AM EDT THU SEP 16 2010) THE LATEST MODEL DATA FROM THE NAM AND HRRR RUC SUGGEST THE STRONGEST WINDS WILL STAY ON THE WEST SIDE OF LAKE MICHIGAN SO THE RISK FOR GALES IN THE GRR NEAR SHORE DO NOT LOOK GOOD. ALSO THE LATEST MARINE OBS DO NOT SHOW GALES OVER THE NORTHERN PART OF LAKE MICHIGAN WHERE THE COLD AIR HAS ALREADY STARTED TO MOVE IN. IN ANY EVENT... THE WINDS WILL QUICKLY SUBSIDE BETWEEN 8 PM AND MIDNIGHT. THUS OUR SMALL CRAFT ADVISORY AS IT IS LOOKS GREAT. && .HYDROLOGY...(400 AM EDT THU SEP 16 2010) RAINFALL AMOUNTS ON AVERAGE OF UNDER AN INCH ARE ANTICIPATED TODAY AND WILL BE MAINLY OF ONLY LIGHT AND MODERATE INTENSITY. HOWEVER SOME BRIEFLY HEAVY RAIN IS POSSIBLE PARTICULARLY WITH ANY STORMS. RAINFALL AMOUNTS/INTENSITY SHOULD NOT BE SUFFICIENT ENOUGH TO CAUSE ANY HYDRO ISSUES GIVEN ANTECEDENT LOW RIVER AND STREAM LEVELS. && .GRR WATCHES/WARNINGS/ADVISORIES... MI....NONE.
