AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
925 PM EDT WED MAY 8 1996

NTRANS VIS LOOP SHOWS A BREAK IN THE OVC OVR SW LWR ATTM MOVG EAST.
BEH HAS ALREADY SCTD AND HAVE INTRODUCED A BREAK IN THE AZO FT.  THE
BREAK APPEARS TO BE CAUSED BY SUBSIDENCE BEHIND THE EARLIER MCS. IT
LOOKS LIKE THE BREAK WILL LAST A COUPLE OF HOURS BEFORE FILLING BACK
IN. SFC ANAL SHOWS THE WARM FRONT ALONG THE IN/MI BORDER. DWPTS SOUTH
OF IT ARE IN THE LOW 60S AND NORTH OF IT IN THE LOW 50S. IFR CONDS
STILL EXIST IN WI AND VFR CONDS IN IL/IN WILL BECOME IFR BY 04Z OR SO.
NEXT BATCH OF TRW IS FIRING OVR THE PLAINS AGAIN IN VCNTY OF WARM FRONT
AND AIDED BY LLJ AND GOOD MOISTURE CONVERGENCE. I EXPECT TONIGHTS MCS
TO FINALLY AFFECT THE FA LATE MORNING THU. THE FOCUS IS FARTHER NORTH
SINCE THE FRONT IS FARTHER NORTH AND THE DIFFLUENT THICKNESS PATTERN
IS ALSO FARTHER NORTH COMPARED WITH THE PAST SEVERAL NIGHTS. I AM
KEEPING IFR CONDS IN THE FTS THRU THU AS THERE WILL BE A LOT OF
MOISTURE IN THE AIR AND SCT TRW NOT TO MENTION GOOD INFLOW FROM THE
SOUTH. ETA BUFKIT SOUNDING FOR THU AFTNOON IN GRR YIELDS LI`S OF -4.
FWC TEMPS A BIT HIGH GIVEN THE AMOUNT OF CLOUD COVER. GOING FCST
LOOKS GOOD.
