AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 153 AM EDT SAT JUL 17 2010 .SYNOPSIS... A WEAKENING FRONT WILL STALL OUT NEAR THE OHIO RIVER TONIGHT AND TOMORROW. ANOTHER COLD FRONT WILL SLOWLY APPROACH FROM THE NORTH ON SUNDAY AND PUSH INTO THE REGION BY MONDAY. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... LOWERED SKY COVER AND INCREASED MIN TEMPS TONIGHT IN THE SOUTH WHERE DEWPOINTS ARE POOLING AND ANY RUNAWAY DROP IN TEMPS WILL BE NIXED. ALSO UPDATED TO REMOVE EVENING SHOWER/THUNDERSTORM WORDING. DID NOT THINK THAT THERE WOULD BE A DIFFERENCE IN LOWS TONIGHT OVER THE HOCKING HILLS AND THE REST OF CENTRAL OHIO WITH DEWPOINTS IN THE MID TO UPPER 60S. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/... REMNANTS OF STALLED FRONT WILL BE NEAR THE OHIO RIVER THROUGH THE DAY. WITH MOISTURE POOLING NEAR THIS BOUNDARY...HEATING AND ANY WEAK DISTURBANCES MOVING THROUGH THE FLOW COULD TRIGGER SOME SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHERN ZONES DURING THE DAY. THERE IS SOME INDICATION THAT A PRE-FRONTAL TROUGH COULD DROP IN FROM THE NORTH DURING THE EVENING AND IT IS NOT COMPLETELY OUT OF THE QUESTION THAT ISOLATED CONVECTION COULD DEVELOP ALONG THIS FEATURE. BIAS CORRECTED MOS SEEMED MOST APPROPRIATE FOR HIGHS WHILE A MOS BLEND LOOKED REASONABLE FOR SATURDAY NIGHT LOWS. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... THE LONG TERM PERIOD WILL START OFF DRY SUNDAY MORNING. THE FORECAST FOCUS WILL BE ON PCPN CHANCES THROUGH THE WEEK. EXPECT SOME THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON HOURS ON SUNDAY IN ADVANCE OF A FRONTAL BOUNDARY. AS BOUNDARY APPROACHES THE AREA PCPN CHANCES WILL INCREASE SUNDAY EVENING INTO MONDAY. BOUNDARY REMAINS NEAR THE AREA FOR TUESDAY KEEPING PCPN IN THE FORECAST DURING THAT TIME FRAME. HIGH PRESSURE WILL THEN WORK INTO THE AREA FOR WEDNESDAY. A WEAK DISTURBANCE WILL SPARK A FEW THUNDERSTORMS AROUND THE AREA FOR THURSDAY AFTERNOON. AT THIS POINT HAVE LIMITED PCPN CHANCES TO SLIGHT CHANCE. DRY CONDITIONS WILL RETURN FOR FRIDAY IN ADVANCE OF ANOTHER SYSTEM MOVING IN FOR NEXT WEEKEND. WENT CLOSER TO THE ECMWF ON PCPN TIMING AS IT HAS BEEN MORE CONSISTENT WITH THIS TIME FRAME. FOR TEMPERATURES WENT WITHIN A FEW DEGREES OF HPC GUIDANCE. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... WEAK FRONTAL BOUNDARY THAT STALLED SOUTH OF THE OHIO RIVER WILL WASH OUT LATER THIS MORNING...ALLOWING INCREASINGLY UNSTABLE AIR TO RETURN TO MUCH OF THE OHIO VALLEY THIS AFTERNOON. THIS WILL LIKELY LEAD TO SCATTERED SHOWERS AND THUNDERSTORMS DEVELOPING FROM SOUTH TO NORTH THROUGH EARLY AFTERNOON.
