NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Sep 10, 2:33 PM EST, 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 333 PM EDT TUE SEP 10 2002 THE 12Z AVN INITIALIZED BETTER THAN THE OTHER MODELS...ESPECIALLY WITH THE 850 MB TEMPERATURES. IT ALSO SEEMS MORE REASONABLE IN HOLDING ONTO THE STRENGTH OF THE SHORTWAVE TRACKING THROUGH THE GREAT LAKES REGION THIS EVENING. WILL BE GENERALLY GOING WITH THE AVN SOLUTION. THE MAIN WEATHER CONCERNS WITH THIS FORECAST DEAL WITH THE SEVERE WEATHER THREAT THIS EVENING...WINDS OVER LAKE MICHIGAN TONIGHT AND TEMPERATURES THROUGH THE PERIOD. VERY UNSTABLE ACROSS THE REGION AT THIS TIME. VALUES ARE LOWER THAN MINUS 6 ACROSS MUCH OF THE AREA. LITTLE IN THE WAY OF A CAP AROUND. ONE BOUNDARY IS PUSHING SLOWLY SOUTHEAST FROM NEAR CLARE...SOUTHWESTWARD TO NEAR MUSKEGON. THE STORMS NEAR HARRISON HAVE BEEN INCREASING AND DEVELOPING SLOWLY SOUTHWESTWARD ALONG THIS BOUNDARY. AM EXPECTING THE STORMS TO CONTINUE TO INCREASE ALONG THIS BOUNDARY...AS IT PUSHES SOUTHEASTWARD THROUGH THE REGION. THE STORM PREDICTION CENTER IS MONITORING THE REGION SOUTH AND EAST OF THIS LINE FOR A POSSIBLE WATCH. WILL MAINTAIN THE CHANCE OF AN EVENING SHOWER OR THUNDERSTORM FOR ALL ZONES. THE FRONT SHOULD PUSH SOUTHEAST OF JXN BY MIDNIGHT. STRONG NORTHERLY GRADIENT MOVES IN. LOOKING AT LAKE SUPERIOR BUOYS...WINDS HAVE BEEN GUSTING INTO THE MID 30S WITH COLD AIR ADVECTION. AM EXPECTING SOME LARGER WAVES TO DEVELOP OVER THE NEARSHORE WATERS ON NORTHERLY WINDS GUSTING TO NEAR 30 KNOTS. MUCH COOLER AND DRIER AIR MOVES IN FOR THE REMAINDER OF THE PERIOD. TEMPERATURES WILL FALL TO MORE SEASONABLE LEVELS. NOTICED THE ETA ACTUALLY DRIES THE SURFACE DEWPOINTS INTO THE 30S SOUTH OF JXN FOR THU NIGHT. WILL GO LOWER THAN MOS NUMBERS FOR THU NIGHT... OTHERWISE THE VALUES LOOK FAIRLY GOOD. MJS EXTENDED FORECAST DISCUSSION... MEDIUM RANGE MODELS ALL INDICATE THAT AN AMPLIFYING SHORTWAVE TROUGH WILL SWING INTO THE GREAT LAKES REGION OVER THE WEEKEND. MRF AND ECMWF DIFFER A BIT ON THE TIMING OF THE PASSAGE OF THE UPPER LEVEL TROUGH. AVN ENSEMBLES ALSO INDICATE SOME SPREAD WITH RESPECT TO TIMING AND OVERALL PREFER A LITTLE SLOWER TIMING GIVING THE AMPLIFYING NATURE OF THE TROUGH. SHOULD HAVE GOOD MOISTURE RETURN AHEAD OF THE FRONT AND THE MODELS DEPICT A PRETTY VIGOROUS BOUNDARY AS IT SWEEPS INTO THE GREAT LAKES. GIVEN THE UNCERTAINTY WITH THE TIMING OF THE UPPER TROUGH PASSAGE WILL CONTINUE PRECIPITATION CHANCES SATURDAY INTO SUNDAY. RELATIVE STRONG AREA OF HIGH PRESSURE WILL BUILD INTO THE REGION BEHIND THE FRONT WITH SOLID COLD ADVECTION. WILL KEEP RELATIVELY COOL AND DRY FORECAST BEHIND THE TROUGH INTO THE EARLY PORTION OF NEXT WEEK. GRAHAM .GRR...NONE.
