AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAND RAPIDS MI 320 AM EDT THU SEP 22 2005 .SHORT TERM... SKIES ARE PARTLY CLLOUDY ACROSS THE CWA. CONVECTIVE DEBRIS CLOUDS FROM AN MCS MOVING EAST ACROSS NORTHERN WISCONSIN CONTINUE TO FLOW INTO THE CWA. KGRR-88D AND SURROUNDING RADARS ALSO SHOW SHOWERS AND SCATTERED STORMS MOVING EAST AHEAD OF A LOW PRESSURE SYSTEM LOCATED OVER NORTHWEST IOWA. THE MOVEMENT OF THIS LOW AND ASSOCIATED COLD FRONT THROUGH THE CWA IS THE FOCUS OF THE FORECAST IN THE SHORT TERM. WERE NOT GOING TO CHANGE MUCH IN THE FORECAST. THE COLD FRONT WILL MOVE THROUGH THE CWA TODAY. THIS MORNINGS CONVECTION WILL HELP KEEP A LID ON INSTABILITY GROWTH AS IT WILL TAKE A WHILE FOR THE CONVECTIVE DEBRIS CLOUDS TO DEPART. IF THE CLOUDS CAN THIN A BIT AND WE GET SOME SUNSHINE...LIS COULD FALL TO -4C OR SO. MODERATE SHEAR...40 TO 50 KTS...IS PROGD ALONG AND AHEAD OF THE COLD FRONT TODAY. THE RIGHT ENTRANCE REGION TO THE UPPER JET WILL AID IN LIFT. TAKEN TOGETHER...SEVERE WX IS A POSSIBILITY WITH HIGH WIND BEING THE MAIN THREAT. THE MOST LIKELY AREA TO SEE STRONG STORMS IS SOUTH OF A LINE FROM MUSKEGON TO MOUNT PLEASANT WHERE THIS MORNINGS CLOUD COVER WILL BE THE THINNEST AND THE CHANCES FOR SIGNIFICANT DESTABILIZATION ARE HIGHEST. THE COLD FRONT WILL MOVE SOUTH OF THE CWA TONIGHT. WELL SEE CLEARING SKIES FROM NORTH TO SOUTH AS HIGH PRESSURE IN ONTARIO FEEDS DRIER AIR INTO THE REGION. THIS HIGH WILL BEGIN TO DRIFT NORTHEAST OF THE CWA ON FRIDAY WE SHOULD SEE A COOL DRY WIND FLOW. THE NEXT SHORT WAVE MOVING THROUGH THE FLOW OVER THE ROCKIES WILL HELP TO DEVELOP ANOTHER SFC LOW IN THE NORTHERN HIGH PLAINS FRIDAY NIGHT. AS SOUTHEAST WINDS DEVELOP AHEAD OF THE LOW...THE COLD FRONT WILL BEGIN TO RETURN NORTH. GFS/NAM/NOGAPS/GEM SUGGEST LIGHT PCPN IS A POSSIBILITY SATURDAY ACROSS THE SOUTHERN CWA AS THE FRONT MOVES NORTH. WELL INCLUDE CHC POPS SOUTH OF I-96 SATURDAY. .LONG TERM... MEDIUM RANGE GUIDANCE IS SIMILAR IN SHOWING THE NRN STREAM BUCKLING SOUTH TOWARD THE EASTERN GREAT LAKES REGION NEXT SUNDAY/MONDAY. THIS SENDS A STRONG COLD FRONT THROUGH THE REGION...WITH SCATTERED SHOWERS AND THUNDERSTORMS A GOOD BET OUT AHEAD OF IT BOTH SATURDAY NIGHT AND SUNDAY. WILL END POPS BY MIDNIGHT SUNDAY NIGHT WITH FROPA...THEN HIGH PRESSURE IS EXPECTED TO BRING A DRY/COOL PERIOD FOR MONDAY AND TUESDAY. NEXT WAVE AND ASSOCIATED FRONTAL SYSTEM IS PROGGED TO AFFECT THE REGION NEXT WEDNESDAY AND WILL CARRY CHC POPS. AS FAR AS RITA IS CONCERNED...IT LOOKS AS THOUGH THE DIP IN THE NRN STREAM...AND THE SURFACE HIGH SLIDING ACROSS THE MIDWEST IN THE MONDAY/TUESDAY TIME FRAME...WILL KEEP THE SYSTEM OVER THE GULF COAST REGION EARLY IN THE WEEK. HOWEVER ITS POSSIBLE THAT RITAS REMAINING MOISTURE COULD GET PICKED UP BY WEDNESDAYS FRONTAL SYSTEM AND PULLED NORTH. THATS A LONG WAY OFF THOUGH. && .GRR WATCHES/WARNINGS/ADVISORIES...SMALL CRAFT ADVISORY NORTH OF HOLLAND. && 93 MEADE
