AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 456 PM EDT WED AUG 02 2006 .SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)... LINE OF CONVECTION IS NOW FORMING AHEAD OF THE COLD FRONT FROM NRN LWR MI SW ACROSS SRN WI. FRONT IS SLOW TO MOVE SOUTHEAST THIS EVENING... SO MAIN THREAT FOR SVR WX IS IN THE NRN CWFA WHERE BEST SURFACE CONVERGENCE AND BETTER DEEP LAYER SHEAR WILL EXIST. MAIN THREAT IS FOR DAMAGING WINDS FROM SHORT BOWING SEGMENTS. SLOW MOVEMENT OF THE FRONT MAY ALSO RESULT IN TRAINING OF CELLS AND A HEAVY RAINFALL THREAT. COLD FRONT EXPECTED TO CLEAR THE SE CWFA THURSDAY MORNING BUT HAVE HELD ON TO A CHANCE OF SHOWERS/TSTMS ALL DAY IN THE SOUTH IN CASE THE FRONT SLOWS/STALLS. OTHERWISE COOLER LESS HUMID AIR FILTERING INTO THE REGION TONIGHT/THURSDAY... WITH MUCH MORE COMFORTABLE CONDITIONS TO FOLLOW. HIGH PRESSURE WILL LEAD TO DRY WEATHER THURSDAY NIGHT THROUGH FRIDAY NIGHT. .MARINE...STRONG SW FLOW AHEAD OF THE FRONT HAS RESULTED IN WAVES OF UP TO 6 FEET TODAY. ARRIVAL OF THE FRONT AND ASSOCIATED BAGGY GRADIENT SHOULD ALLOW WINDS/WAVES TO DIMINISH THIS EVENING. HOWEVER THE NORTH FLOW COLD ADVECTION ON THURSDAY WILL LIKELY CAUSE THEM TO KICK UP AGAIN. WE COULD NEED ANOTHER SMALL CRAFT ADVISORY ON THURSDAY...PARTICULARLY SOUTH OF GRAND HAVEN. .LONG TERM (SATURDAY THROUGH WEDNESDAY)... A SFC HIGH PRESSURE RIDGE WILL PRODUCE DRY WX SATURDAY INTO SUNDAY AND TEMPERATURES WILL CONTINUE TO AVERAGE ABOVE NORMAL. A WEAK COLD FRONT WILL DROP IN FROM THE NW SUNDAY NIGHT INTO MONDAY BRINGING A CHC FOR A FEW SHOWERS AND STORMS. HOWEVER PROBABILITIES OF RAIN WITH THAT SYSTEM LOOK QUITE LOW SINCE GUIDANCE RH PROGS INDICATE MOISTURE WITH THE FRONT WILL BE VERY LIMITED. THEN BEYOND THAT ANOTHER SFC HIGH PRESSURE AREA WILL TAKE CONTROL OF OUR WX AND PRODUCE DRY WX WITH SEASONABLE TEMPS FROM MONDAY NIGHT THROUGH THE MIDDLE PORTION OF NEXT WEEK. && .GRR WATCHES/WARNINGS/ADVISORIES...HEAT ADVISORY IN EFFECT THROUGH 8 PM THIS EVENING FOR THE SOUTHERN HALF OF THE GRR CWFA. SMALL CRAFT ADVISORY IN EFFECT FOR THE LAKE MI NEARSHORE FROM ST JOSEPH TO MANISTEE UNTIL 11 PM. && MEADE LAURENS
