Area forecast discussion, Jun 9, 9:21 PM EDT, 22 hours 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 900 PM EDT SAT JUN 8 1996 KGRR-88D SHOWS HEAVY RW IN NW IN JUST SOUTH OF THE ST JOE RIVER. 88D SHOWS 2.8 IN STP AND GROUND TRUTH CONFIRMS THIS. TRAIN ECHO IS SETTING UP FROM FWA-SBN. HAVE BEEN IN CONTACT WITH NCRFC AND WE WILL CONTINUE TO MONITOR THIS DEVELOPING SITUATION. MOST OF THE RW/TRW ACTIVITY IS SOUTH OF JXN-AZO LINE AND THAT TREND SHOULD CONTINUE AS THE PCPN MOVES NW IN RESPONSE TO THE UPR LOW SPINNING IN WRN KY. FOG HAS ALREADY MOVED BACK IN ALONG WITH THE LOW CIGS AND I WOULD EXPECT THIS TREND TO CONTINUE OVERNIGHT. DRY SLOT IS KICKING OFF THE TRW BUT AT THIS TIME I DO NOT THINK THAT ENOUGH DRY AIR WILL MAKE IT NORTH OF I-96 TO GET RID OF THE FOG AND LOW CIGS. LOTS OF LLVL MOISTURE WILL ENSURE THIS. NOT A LOT OF CHANGE ANTICIPATED FOR THE NEXT 24 HRS AS UPR LOW CONTINUES ITS SLOW NWD TREK. FCST SOUNDINGS FROM ETA BUFKIT GIVE LIS OF -2 TO -4 ON MONDAY SO THE THREAT OF TRW WILL CONTINUE. WF
