AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 753 PM EDT FRI MAY 29 2009 .SYNOPSIS... A COLD FRONT WILL MOVE ACROSS NORTHERN OHIO AND NORTHWEST PENNSYLVANIA TONIGHT AND REACH THE OHIO RIVER BY SATURDAY MORNING. ANOTHER COLD FRONT WILL DROP SOUTHEAST ACROSS THE AREA SATURDAY NIGHT. HIGH PRESSURE WILL SLIDE ACROSS THE REGION ON SUNDAY AND MAY BECOME A FOCUS FOR SHOWERS AND THUNDERSTORMS ON MONDAY. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... UPDATED MAINLY ALONG THE LAKESHORE FOR SCATTERED SHOWERS AND THUNDERSTORMS ASSOCIATED WITH FRONT/TROUGH THAT IS MOVING THROUGH. ALSO UPDATING THE MARION COUNTY AND WYANDOT COUNTY AREAS. THE ACTIVITY IS DIURNALLY DRIVEN AND WILL DECREASE AFTER DARK. OTHERWISE EXPECT SOME DRIER AIR TO SPILL IN ACROSS THE REGION IN THE WAKE OF THE TROUGH/WEAK FRONT. THE DRY AIR AND DECREASING CLOUDS LATE IN THE NIGHT SHOULD ALLOW FOR LOWS TO DIP INTO THE UPPER 40S FOR PORTIONS OF THE AREA. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY NIGHT/... ANOTHER WIND SHIFT/FRONT WILL MOVE ACROSS THE REGION LATE SATURDAY INTO SATURDAY NIGHT. THIS BOUNDARY COULD AGAIN PRODUCE SOME ISOLATED THUNDERSTORMS AS SOME COOLER AIR ALOFT MOVES ACROSS THE REGION. LOW LEVELS DONT LOOK ALL THAT MOIST BUT IF ENOUGH CONVERGENCE IS REALIZED ALONG THE BOUNDARY THEN SOME ISOLATED STORMS MAY BE POSSIBLE. MAY BE SOME SMALL HAIL WITH ANY OF THE STRONGER THUNDERSTORMS THAT CAN DEVELOP LATE AFTERNOON INTO THE EVENING. A STRONGER FRONT LOOKS TO SETTLE INTO THE REGION ON MONDAY. HARD TO PINPOINT ITS LOCATION AT THIS TIME BUT THIS WILL BE CRITICAL ON WHERE TO PLACE THE BEST RAIN CHANCES. AN MCS WILL BE POSSIBLE NEAR THIS BOUNDARY ON MONDAY BUT DONT WANT TO GO MORE THAN CHANCE POPS AT THIS TIME. TEMPERATURES WILL BE ON THE COOL SIDE OF SEASONAL AVERAGES OVER THE WEEKEND BUT WILL WARM ON MONDAY WITH INCREASING SOUTHERLY FLOW. && .LONG TERM /TUESDAY THROUGH FRIDAY/... THE LONG TERM BEGINS ON TUESDAY WITH A COLD FRONT IN THE VICINITY. MANUAL PROGS HAVE IT ACROSS THE SOUTHERN TIER OF COUNTIES. GFS AND 00Z ECMWF ARE IN GENERAL AGREEMENT WITH THE SURFACE TROF POSITION. THROUGH THE DAY TUESDAY THE ECMWF HANGS THE FRONT ACROSS THE AREA WHILE THE GFS TAKES IT SOUTH INTO WVA AND KY. HAVE TENDED TO FOLLOW THE SLOWER ECMWF THROUGH THE EXTENDED WHICH BRINGS THE BULK OF THE DEEP MOISTURE THROUGH THE AREA TUESDAY NIGHT AND WEDNESDAY MORNING. HIGH SURFACE PRESSURE WILL BUILD IN FOR WEDNESDAY AFTERNOON BREAKING CLOUDS FROM THE NORTHWEST. WILL INCLUDE CHANCE POPS WEDNESDAY BUT SHAVE BACK TO SLIGHT CHANCE NW IN THE AFTERNOON. EXPECT DRY CONDITIONS FOR THE REMAINDER OF THE FORECAST. AS THE BROAD HIGH CONTINUES TO BUILD IN. WILL CONTINUE WITH CHANCE POPS FOR FRONTAL PASSAGE. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... SHOWERS/THUNDERSTORMS MAKING THEIR EASTWARD...MAINLY ALONG AND EAST OF I-71. SOME INSTABILITY TO WORK WITH...BUT THAT WILL BE DIMINISHING WITH TIME. FOR EASTERN TAFS HAVE CB AND/OR VCSH AS THE ACTIVITY SHOULD BE WEAKENING. IMPACT AT ANY ONE SPOT ABOUT AN HOUR. FRONT MOVING THROUGH TOLEDO AND WILL TAKE WINDS AROUND TO A WNW DIRECTION...BUT OVERNIGHT WINDS WILL DIMINISH AND BECOME LIGHT/VARIABLE. MAINTAINED PREVIOUS FORECAST AT YNG/ERI THAT FOLLOWED THE NAM GUIDANCE WITH SOME LOW LEVEL MOISTURE IN PLACE OVERNIGHT. NOT OVERLY CONFIDENT IN THIS BUT LEFT THE MVFR CONDITIONS OVERNIGHT AT YNG/ERI ONLY. OTHERWISE ALL VFR. WINDS WILL COME BACK AROUND TO THE WSW SATURDAY IN ADVANCE OF THE NEXT FRONT. ANY SHRA/TS ACTIVITY WITH THIS SHOULD BE AFTER 18Z. OUTLOOK...MAINLY VFR. BEST CHANCE FOR MVFR TUE/WED. && .MARINE... WEAK TROUGH TO CROSS THE LAKE THIS EVENING. WINDS AHEAD OF AND IMMEDIATELY BEHIND THE FRONT WILL BE SOMEWHAT STRONG...10-20KTS BUT WAVES SHOULD REMAIN BELOW SMALL CRAFT CRITERIA. ANOTHER WEAK WAVE WILL CROSS THE LAKE SATURDAY AFTERNOON BUT AGAIN...WINDS AND WAVES WILL BE BELOW SMALL CRAFT CRITERIA. HIGH PRESSURE SUNDAY AND MONDAY WILL YIELD LIGHT WINDS AND MINIMAL WAVES...HOWEVER A FRONT WILL DIP SOUTHWARD TOWARD THE LAKE TUESDAY MORNING. IT WILL BE SLOW TO CROSS THE LAKE...WINDS WITH THE FRONT DO NOT LOOK ALL THAT IMPRESSIVE BUT POST-FRONTAL NORTHEASTERLY FLOW COULD EASILY YIELD SMALL CRAFT CONDITIONS AND AN ELEVATED RISK OF RIP CURRENTS BY THE MIDDLE OF NEXT WEEK. && .CLE WATCHES/WARNINGS/ADVISORIES...
