AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CLEVELAND OH 337 PM EDT TUE MAY 27 2014 .SYNOPSIS... A COLD FRONT OVER THE LAKES WILL SLOWLY PUSH SOUTH ACROSS THE AREA TONIGHT THROUGH WEDNESDAY...STALLING NEAR THE OHIO RIVER WEDNESDAY NIGHT INTO THURSDAY. HIGH PRESSURE WILL BUILD SOUTH INTO THE REGION LATER THURSDAY AND FRIDAY PUSHING THE COLD FRONT OFF TO THE SOUTH. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... THERMODYNAMICS AND WEAK LOW LEVEL CONVERGENCE CONTINUE TO CAUSE SOME ISOLATED THUNDERSTORMS. AT WORST CASE THE COVERAGE COULD REACH LOW LEVEL SCATTERED THROUGH THE EVENING. WE WILL THEN WATCH THE CONVECTION OVER MICHIGAN AND ADDITIONAL DEVELOP OVER ONTARIO AS A WEAK FRONT/WIND SHIFT SAGS SOUTHWARD INTO NW PA AND NORTHERN OHIO. AS THIS POINT THE BETTER CONVERGENCE APPEARS THAT IT WILL BE LOCATED OVER THE EASTERN THIRD OF THE COUNTY WARNING AREA. ALTHOUGH OUTFLOW BOUNDARIES FROM THE CURRENT CONVECTION WILL INFLUENCE THIS. IT WILL BE ANOTHER WARM NIGHT WITH DEWPOINTS HOLDING IN THE LOWER 60S. THIS SHOULD KEEP LOWS INT HE LOWER TO MIDDLE 60S FOR MOST LOCATIONS. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/... WEDNESDAYS CONVECTIVE DEVELOPMENT WILL BE DIFFICULT TO FORECAST WITH UNCERTAINTY WHERE THE FRONTAL BOUNDARY/WIND SHIFT/OUTFLOW BOUNDARIES WILL RESIDE. CURRENTLY WE BELIEVE THE GREAT THREATS FOR CONVECTION WILL BE ACROSS THE SOUTHERN HALF OF THE COUNTY WARNING AREA WHERE THE BETTER CONVERGENCE SHOULD BE LOCATED. THE ONLY LOCATIONS THAT MAY AVOID CONVECTION ON WEDNESDAY WOULD BE ACROSS NW PA. THIS BOUNDARY SHOULD CONTINUE TO SAG SOUTHWARD WEDNESDAY NIGHT INTO THURSDAY NIGHT AS HIGH PRESSURE BUILDS SOUTHWARD ACROSS ONTARIO. HOWEVER NORTHWEST FLOW OVER THE AREA WILL BRING ANOTHER PIECE OF JET ENERGY ACROSS NY STATE ON FRIDAY. THIS WILL SEND ANOTHER WEAK COLD FRONT INTO THE REGION. THE BETTER CONVERGENCE AND LIFT WILL BE ACROSS NW PA SO WILL KEEP A SLIGHT CHANCE FOR THAT REGION. ANOTHER AREA OF HIGH PRESSURE WILL BUILD IN BEHIND THIS FRONT FROM ONTARIO. TEMPERATURES THROUGH FRIDAY WILL BE VERY CLOSE TO SEASONAL AVERAGES. && .LONG TERM /SATURDAY THROUGH TUESDAY/... MODELS IN GOOD AGREEMENT FOR THE WEEKEND WITH A RIDGE OF HIGH PRESSURE OVER THE AREA. THE HIGH MOVES OFF THE SOUTHEAST COAST LATE SUNDAY ALLOWING NEXT SYSTEM TO APPROACH FROM THE WEST ON MONDAY. ECMWF CONTINUES TO BE A LITTLE FASTER WITH THE NEXT SYSTEM THAN THE GFS. MODELS NOT IN GOOD AGREEMENT WITH THE TRACK AND TIMING OF SYSTEMS MONDAY INTO TUESDAY...AS GFS SLOWER AND FURTHER NORTH WITH SYSTEM. HOWEVER...BOTH SHOW ABOVE NORMAL TEMPS WITH A CHANCE OF THUNDERSTORMS. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... WEAK COLD FRONT STRETCHING FROM LOW NORTH OF LAKE ONTARIO ACROSS LOWER MICHIGAN.

WEAK COLD FRONT NORTH OF THE LAKE WILL MOVE ACROSS THE LAKE LATE TONIGHT. WINDS GRADUALLY TURN TO THE NORTHEAST AND WINDS INCREASE TO 10 TO 15 KNOTS BY THURSDAY SETTING UP CHOPPY CONDITIONS ACROSS THE LAKE. SHOULD REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA.
