NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Jul 7, 8:51 PM EST, 3 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 951 PM EDT MON JUL 7 2003 AM LEANING TOWARD REMOVING THE CHANCE OF THUNDERSTORMS FROM THE NRN TWO THIRDS OF THE CWFA TONIGHT...OR AT LEAST LOWERING THE 40 POP TO JUST A SLIGHT CHANCE (20 PCT). ALL OF THE CONVECTIVE DEVELOPMENT THIS EVENING HAS BEEN FAVORING THE AREA FROM IOWA TO NRN OHIO WHERE BEST AXIS OF MOISTURE AND INSTABILITY EXISTS. ONLY PROBLEM IS THAT THE COLD FRONT IS STILL OVER ERN WI AND WILL BE COMING THROUGH OVER THE NEXT FEW HOURS. DECENT SURFACE CONVERGENCE EXISTS ALONG THE BOUNDARY...BUT NOTHING HAS DEVELOPED ALONG IT YET (WITH EXCEPTION OF FARTHER NORTH OVER ERN UPR MI). DEW POINTS ARE CURRENTLY IN THE MID 60S ACROSS THE CWFA WITH MID TO UPPER 70S TO THE SOUTH. BELIEVE MCS COMING EAST FROM NRN ILLINOIS WILL RIDE THE DEW POINT GRADIENT ALONG THE MI/IN BORDER... POSSIBLY CLIPPING THE I-94 CORRIDOR. WILL THEREFORE LEAVE A 30-40 POP GOING THERE... AND UPDATE THE HWO TO REFLECT LATEST SPC SWODY1. LOW LEVEL NORTHWEST FLOW BEHIND THE SURFACE FRONT LATER TONIGHT SHOULD DRIVE THE DEW POINTS DOWN A BIT...WITH MUCH OF THE NW CWFA AROUND OR BELOW 60F BY 12Z. THIS SHOULD LEAD TO MORE COMFORTABLE CONDITIONS FOR TUESDAY. LATEST GFS/ECMWF SOLUTIONS FOR THE WED-THU TIME FRAME ARE A LITTLE CONCERNING SINCE WE CURRENTLY HAVE A DRY FCST. WILL WAIT FOR NEW 00Z GUIDANCE TO MAKE ANY CHANGES THAT FAR OUT. MEADE .GRR...NONE.
