AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 1040 PM EDT WED AUG 23 2006 .UPDATE... LATEST SFC ANALYSIS AT 02Z SHOWS THE QUASI-STATIONARY FRONT EXTENDING FROM JUST SOUTH OF KMSN...TO JUST NORTH OF KORD...AND THEN NEAR THE SW TIP OF LOWER MICHIGAN. A FEW SMALL CLUSTERS OF SFC BASED CONVECTION HAVE BEEN ONGOING RIGHT ALONG THIS FRONT. THE MOST NOTABLE STORM WAS THE RIGHT MOVER THAT MOVED THROUGH MICHIGAN CITY INDIANA AND PRODUCED A MEASURED 106 MPH WIND GUST AT THE COAST AND REPORTS OF A TORNADO. THIS SFC BASED CONVECTION IS STAYING JUST SOUTH OF THE CWFA...RIDING ALONG THE SFC INSTABILITY GRADIENT NEAR THE FRONT. OVER THE GRR CWFA...WE HAVE BEEN IN A LULL BETWEEN THE DYING AREA OF PCPN EARLIER THIS AFTERNOON AND THE PCPN NEAR THE FRONT. THE DRY ATMOSPHERE HAS BEEN GRADUALLY MOISTENING...WITH MANY LOCATIONS NOW REPORTING CLOUD LAYERS AROUND 6K TO 8K FEET. IN THE LAST HALF AN HOUR OR SO...ISOLATED CONVECTION HAS BEEN FIRING SOUTH OF A LINE FROM KGRB TO KMBL. THIS ISOLATED CONVECTION IS EVIDENCE THAT THE ATMOSPHERE HAS MOISTENED ENOUGH AND BECOME UNSTABLE ENOUGH TO ALLOW THE MID LEVEL WAA/THETA E ADVECTION AHEAD OF THE INCOMING WAVE TO START PRODUCING PCPN. SHOWALTER INDICES ARE FORECAST TO FALL DOWN TO AROUND -3 OR SO OVERNIGHT. WE EXPECT THAT THIS DEVELOPMENT OF UNORGANIZED CONVECTION WILL CONTINUE OVER THE NEXT FEW HOURS AND BEGIN AFFECTING MORE OF THE CWFA. THE BEST THREAT OF RAIN WILL CONTINUE TO BE FOUND CLOSER TO THE FRONT AS THE ORGANIZED CONVECTION CONTINUES ALONG THE FRONT. WITH THE ELEVATED NATURE OF THE CONVECTION OVER THE AREA...THE SEVERE THREAT IS DIMINISHING AS TIME GOES ON AS THE BOUNDARY LAYER COOLS. THE THREAT WILL NOT COMPLETELY END AS FREEZING LEVELS AROUND 12K FT OR SO WILL KEEP MARGINALLY LARGE HAIL POSSIBLE IN THE BETTER UPDRAFTS. ALSO WITH DEEP LAYER SHEAR VALUES OF 30 TO 45 KNOTS /HIGHEST NORTH/ AN ISOLATED REPORT OF WIND DAMAGE CAN NOT BE RULED OUT. THE FORECAST HAD THINGS WELL IN HAND AND ONLY MINOR ADJUSTMENTS WERE MADE. && .GRR WATCHES/WARNINGS/ADVISORIES...NONE. NJJ
