AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
1230 PM EDT TUE JUN 28 2005

.UPDATE...
VISIBLE IMAGERY SHOWS A LINE OF CU WITH THE FRONT FROM NEAR CAD
TO BETWEEN LDM AND MBL.  STRONG HEATING CONTINUES IN THIS AREA AS
WELL.  SOUTH OF THIS BOUNDARY SPC WEBPAGE HAS
ML CAPE VALUES UP 2500 J/KG...DCAPE IS HIGH AS WELL.  THUS ANY
STRONGER THUNDERSTORM THAT DOES FORM WILL NEED TO BE WATCHED FOR
POSSIBLE STRONG DOWNDRAFTS.   I DID NOTICE THAT MID LEVEL LAPSE
RATES APPEAR TO BE MORE FAVORABLE FOR HAIL AS COMPARED TO PREVIOUS
DAYS WITH VALUES NEAR 7 DEG C FROM 700 TO 500 MB.  THIS COULD PERHAPS
LEAD TO A HIGHER HAIL THREAT THAN WE HAVE SEEN. WILL CONTINUE WITH
THE CHANCE PROBABILITIES FOR THUNDERSTORMS THIS AFTERNOON AND
EVENING.

.GRR WATCHES/WARNINGS/ADVISORIES...NONE.
