NWS Grand Rapids, MI wrote its last area forecast discussion before the first event at Sep 19, 10:04 AM EST, 4 hours 6 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1104 AM EDT THU SEP 19 2002 FORECAST CHALLENGES ARE PLENTY THIS AFTERNOON. SATELLITE IMAGES SHOWS A PATCH WORK OF OVERCAST AND SCATTERED CLOUDS OVER THE CWA. OVERCAST SKIES PREVAIL OVER THE NW 2/3 OF THE CWA...WHILE THE SOUTHEAST IS SEEING SUNSHINE. ANOTHER LARGE HOLE IN THE CLOUDS SITS OVER SOUTHERN LAKE MICHIGAN. AT THE SAME TIME A FEW SHOWERS AND STORMS HAVE POPPED UP FROM TIME TO TIME OVER THE REGION. THE QUESTIONS OF THE AFTERNOON WILL BE HOW MUCH SUNSHINE BREAKS OUT...AND WHERE ARE THE BEST CHCS FOR CONVECTION. DESPITE THE DECENT LOW LEVEL MOISTURE AVAILABLE THIS AFTERNOON... THERE IS NOT A GOOD TRIGGER FOR ORGANIZED CONVECTION. THE LOW LEVEL JET RESPONSIBLE FOR THE MORNING CONVECTION OVER THE NW CWA HAS SHIFTED NORTHEAST. CAPES THIS AFTERNOON SHOULD REMAIN IN THE 500-1000 J/KG RANGE WITH LI/S AROUND -2...LEAVING THE POSSIBILITY OF SCATTERED CONVECTION. THE ONLY FOCUS TO THE CONVECTION MAY BE TOWARD EVENING WHEN AN AREA OF UPPER DIVERGENCE DEVELOPS OVER CENTRAL LAKE MICHIGAN. WILL THEREFORE KEEP LIKELY POPS GOING OVER THE NW CWA...WITH CHC ELSEWHERE. AS FOR THE SUNSHINE CHCS/LOCATIONS...ALTHOUGH SOME PERIODS OF SUNSHINE SHOULD BE SEEN ACROSS MOST OF THE CWA THERE SHOULD BE ENOUGH LOW LEVEL MOISTURE FOR CU TO FILL IN MOST CLOUD BREAKS DURING THE AFTERNOON. SO IM NOT ANTICIPATING A LOT OF SUN...THE MENTION OF PARTLY SUNNY STILL LOOKS GOOD. STILL...ANY SUNSHINE SHOULD HELP RAISE THE TEMPS BEYOND THE CURRENT FORECAST...SO WILL TWEAK UPWARD A BIT. JK .GRR...NONE.
