AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1148 AM EDT MON MAY 31 2004 .UPDATE... I WILL UPDATE THE ZONES TO SCATTERED SHOWERS AND THUNDERSTORMS FOR THIS AFTERNOON ACROSS THE CWA. THE PRIMARY RAIN BAND HAS LIFTED NORTH OUT OF THE CWA SO THAT WILL LEAVE US WITH INSTABILITY SHOWERS UNDER THE UPPER LEVEL COLD POOL. BASED ON THE ETA SHOWING ONLY MARGINAL INSTABILITY (850 LI ON ETA POSITIVE THIS AFTERNOON OVER SW LOWER MICHIGAN) AND WITH DNVA AND CONSIDERABLE MID LEVEL DRY AIR MOVING IN...NOT TO MENTION SFC WINDS WILL BE OFF LAKE MICHIGAN SEEMS THE RAIN ACTIVITY THIS AFTERNOON SHOULD BE LIMITED. THE RUC IS MORE AMBIOUS ABOUT IT BUT HAS SIMILAR IDEAS ON THE CONVECTION (SCATTERED MOSTLY ). EVEN SO...RUC SOUNDING SUGGEST NEAR 1000 J/KG WITH TEMPS NEAR 70F AND SFC DEW POINTS NEAR 60F AT 21Z...ETA HAS NO CAPE AT THAT POINT NEAR GRR. THE 0-6 KM SHEAR (ETA) NEAR GRR IS NEAR 80 KNOTS AT 1PM BUT FALLS TO 35 KNOTS BY 3 PM. SO ISOLATED THUNDERSTORMS WITH A SLIGHT RISK OF MARGINAL LARGE HAIL (FREEZING LEVEL FALLS TO NEAR 8500 FT BY 3 PM) AND WIND GUSTS TO 50 KNOTS IS THERE (MID LEVEL DRY AIR AND 30 TO 35 KNOTS FROM 2000 FT THROUGH 10000 FT). BEST INSTABILITY WILL BE OVER THE SOUTHERN COUNTIES WERE MORE SUNSHINE WILL BE SEEN. AN ISOLATED SHORT LIVED TORNADO WOULD BE POSSIBLE IF STORMS DEVELOPED NEAR TRIPLE POINT THIS AFTERNOON. HOWEVER THE TRIPLE POINT SHOULD BE EAST OF CWA BEFORE IT IS A PROBLEM. WE DROPPED URBAN AND SMALL STREAM FLOOD ADVISORY ALLEGAN...OTTAWA AND MUSKEGON COUNTY FOR THIS AFTERNOON BUT WILL CONTINUE IT FOR MASON AND OCEANA BASED ON CALLS TO COUNTIES INDICATING THE NORTHERN TWO COUNTIES WERE THE ONLY COUNTIES WERE THERE WAS SOME WATER OVER ROADS YET. THE PRIMARY PRECIPITATION BAND ASSOCIATED OCCLUDED FRONT IS LIFTING NORTH OUT OF THE CWA. THE DRY SLOT HAS ALREADY MOVED INTO THE SOUTHWEST CORNER OF THE STATE. THERE IS A SECOND AREA OF SHOWERS AND THUNDERSTORMS ASSOCIATED WITH 850MB WARM ADVECTION (IOWA TO IL AT 15Z) MOVING UNDER TO UPPER LEVEL COLD POOL. THIS STUFF SHOULD MOVE INTO SOUTHWEST LOWER LATER THIS AFTERNOON BUT WILL STILL GO WITH SCT SHOWERS AND THUNDERSTORMS SINCE INSTABILITY CONTINUES TO DECREASE WITH TIME AND MODELS SHOW MEAN DEEP RH CONTINUES TO DECREASE AS THIS AREA MOVES EAST INTO THE CWA. && .GRR...SMALL CRAFT ADVISORY THROUGH THE ENTIRE NEAR SHORE AREA INTO THIS EVENING.
