AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 735 PM EDT WED APR 7 2010 .SYNOPSIS... SURFACE LOW PRESSURE LOCATED OVER WESTERN ILLINOIS WILL SLOWLY TRACK NORTHEAST ACROSS ONTARIO INTO QUEBEC BY FRIDAY. A COLD FRONT WILL SLIDE ACROSS THE REGION TONIGHT INTO THURSDAY. HIGH PRESSURE WILL RETURN TO THE REGION BY SATURDAY AND PERSIST INTO THE WEEKEND. A WEAK FRONTAL BOUNDARY MAY LAY ACROSS THE REGION FROM SUNDAY INTO EARLY NEXT WEEK. && .NEAR TERM /THROUGH THURSDAY/... STATIONARY BOUNDARY REMAINS THE SOUTH SHORE OF LAKE ERIE TO LOW PRESSURE LOCATED OVER WESTERN ILLINOIS. THIS AREA OF LOW PRESSURE WILL TRACK NORTHEAST ALONG THIS BOUNDARY WITH A COLD FRONT LOCATED SOUTH IT. THIS COLD FRONT WILL BE SLOW TO MOVE EASTWARD BUT SHOULD MOVE INTO AT LEAST WESTERN OHIO TONIGHT. SHOWERS AND THUNDERSTORMS WILL CONTINUE TO SPREAD FROM WEST TO EAST ACROSS THE REGION TONIGHT. STILL SOME CONCERN THAT THERE COULD BE A FEW STRONGER THUNDERSTORMS ACROSS WESTERN OHIO THIS EVENING. AS THE REGION LOSSES THE HEAT OF THE DAY WE SHOULD SEE THIS THREAT DECREASE OVERNIGHT. HOWEVER THE THREAT OF A STRONGER THUNDERSTORM WILL BE POSSIBLE ALONG THE FRONT AS IT MOVES EASTWARD. WILL CONTINUE THIS MENTION IN THE HWO. RAIN ACROSS THE AREA SHOULD PROVIDE FOR COOLER TEMPERATURES TONIGHT WITH MOST LOCATIONS IN THE 50S. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... COLD FRONT WILL SLOWLY MOVE ACROSS THE REMAINDER OF THE REGION ON THURSDAY WITH SHOWERS AND A FEW RUMBLES OF THUNDER AHEAD OF THE FRONT. IN THE WAKE OF THE FRONT SHOWERS WILL CONTINUE WITH SOME ENHANCEMENT POSSIBLE OFF OF LAKE ERIE AS TEMPERATURES CONTINUE TO FALL THROUGH THE DAY. HIGHS THURSDAY WILL BE EARLY THEN FALL INTO THE 40S AT MOST LOCATIONS. THE LAKE EFFECT RAIN SHOWERS...MAYBE A FEW SHOW SHOWERS....WILL BE POSSIBLE INTO FRIDAY NIGHT. ANY SNOW SHOULD ONLY MIX WITH THE RAIN AT TIMES. THE VERY WARM TEMPERATURES THE LAST FEW DAYS HAS WARMED THE GROUND WHICH SHOULD KEEP ANY ACCUMULATIONS FROM OCCURRING. IT WILL FEEL MUCH COLDER THURSDAY THROUGH INTO FRIDAY AS THE UPPER LEVEL LOW PASSES. HIGHS ON FRIDAY SHOULD DIP BELOW SEASONAL AVERAGES WHICH ARE NOW IN THE MIDDLE 50S. LOWS THURSDAY NIGHT AND FRIDAY NIGHT WILL RETURN TO SEASONAL LEVELS. WINDS LOOK TO STAY UP ENOUGH THURSDAY NIGHT TO LIMIT THE FROST THREAT BUT BY FRIDAY NIGHT LIGHTER WINDS AND PARTLY CLOUDY SKIES SHOULD LEAD TO AT LEAST SOME PATCHY FROST. HIGH PRESSURE WILL TAKE BACK CONTROL OF THE WEATHER ACROSS NORTHERN OH AND NW PA INTO SATURDAY. WITH MORE SUNSHINE AND A RETURN TO SOUTHERLY WINDS SHOULD ASSIST IN A RETURN TO HIGHS IN THE MID 50S TO LOWER 60S. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... WEAK FRONTAL BOUNDARY WILL BE ACROSS A PORTION OF THE AREA ON SUNDAY AND COULD GENERATE A FEW SHOWERS...MAYBE A THUNDERSTORM. MODELS TRYING TO INDICATE WEAK FRONTAL BOUNDARY ACROSS THE AREA ON MONDAY THAT WILL LIFT AWAY FROM THE AREA BY TUESDAY AS STRONG UPPER RIDGING BECOMES ESTABLISHED OVER THE AREA. FOR NOW LEFT SLGT CHC POPS FOR MONDAY ESPECIALLY ACROSS NE OH AND NW PA WITH THE FRONTAL BOUNDARY...BUT BEYOND THAT THROUGH THE END OF THE PERIOD HIGH PRESSURE WILL DOMINATE. WITH PLENTY OF SUNSHINE AND RIDGING LEANED A BIT TOWARDS WARMER SIDE OF GUIDANCE FOR TEMPERATURES. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... COMPLICATED FORECAST. SLOW MOVING FRONT WITH LINE OF SHOWERS/THUNDERSTORMS ACROSS IND. TIMING DIFFICULT WITH WAVES OF LOW PRESSURE RIDING THE FRONT AND SLOWING ITS EASTWARD PROGRESS.

SOME GUSTS THURSDAY...MOST LIKELY WEST. .OUTLOOK...NON VFR THROUGH THE DAY INTO THURSDAY NIGHT...THEN MAINLY VFR THROUGH WEEKEND. && .MARINE... WINDS ARE NOT AS STRONG TODAY AS THEY WERE YESTERDAY AND SHOULD DIMINISH EVEN MORE THIS EVENING AHEAD OF AN APPROACHING COLD FRONT. HAVE HAD TO SLOW THE TIMING OF THE FRONT DOWN SOME MORE. IT NOW APPEARS THAT FRONT WON'T CLEAR THE LAKE TILL SOMETIME EARLY THURSDAY AFTERNOON. THERE SHOULD BE SOME SHOWERS AND STORMS AHEAD OF THE FRONT OVERNIGHT AND THURSDAY MORNING. WINDS BEHIND THE FRONT WILL START OUT SW BUT SHOULD GO TO WEST TOMORROW AFTERNOON. SPEEDS WILL INCREASE DURING THE AFTERNOON AND MOST OF THE NEARSHORE WILL SEE LEGITIMATE SMALL CRAFT CONDITIONS. SPEEDS WILL BEGIN TO SLOWLY DIMINISH LATE THURSDAY NIGHT AND FRIDAY. ON SATURDAY A SURFACE RIDGE WILL MOVE EAST ACROSS THE LAKE WITH THE FLOW AGAIN BECOMING SW. SW FLOW LESS THAN 15 KNOTS WILL THEN CONTINUE INTO SUNDAY. AT THAT POINT THE MODELS BEGIN TO SHOW SOME DIFFERENCES. THERE IS SOME SUGGESTION THAT ANOTHER HIGH WILL BUILD OVER THE REGION FROM THE NORTH FOR THE START OF NEXT WEEK.
