1040 AM EDT THU MAY 8 1997

THE LATEST SFC ANAL SHOWS A COLD FRONT ON THE WEST SHORE OF LAKE MI.
ADAP SHOWS SOME MOISTURE CONVERGENCE ALONG THE FRONT WITH THE MAX BEING
IN NE IL. SKIES ARE CLOUDY AHEAD OF THE FRONT AND KGRR-88D SHOWS
SCATTERED SHOWERS PERSISTING EVEN BACK TO THE LAKE. BEHIND THE FRONT,
LOW CLOUDS AND FOG ARE BEGINNING TO FALL APART AS SOME DRIER AIR MOVES
IN AS EVIDENCED BY THE LATEST VIS LOOP. THE DIFFERENTIAL HEATING TAKING
PLACE ON THE BACK EDGE OF THE CLOUD DECK IS BEGINNING TO DESTABILIZE
THE ATM SOMEWHAT AS ENHANCED CU WAS SEEN DEVELOPING IN CENTRAL WI.  IN
ADDITION, A STRONG S/W IN SRN CANADA IS SWINGING A LOBE OF ENERGY SOUTH
THROUGH MN WHICH IS ALSO HELPING TO DESTABILIZE THINGS. THE BACK EDGE
OF THE CLOUDS WAS APPROACHING CENTRAL WI AND BELIEVE THAT SOME CLEARING
WILL INDEED OCCUR ACROSS THE FA THIS AFTERNOON. MODIFIED GRB SOUNDING
INDICATES THAT LI'S WILL FALL BELOW ZERO AND TT WILL CLEAR 50 AS THE
SFC HEATS TO THE MID 60S AND MID LVL TEMPS FALL BELOW -20.  NATURALLY,
THIS WON'T OCCUR ACROSS THE FA UNTIL MID-LATE AFTNOON, BUT
THUNDERSTORMS STILL APPEAR TO BE A PLAYER IN THIS AFTERNOONS WX. HAIL
IS A POSSIBILITY AS UPR LVL TEMPS COOL. WE WILL NOT CHANGE MUCH IN THE
CURRENT ZFP. BELIEVE THAT FCST TEMPS WILL STILL BE REACHED BUT NOT TILL
LATE AFTNOON.
