AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 739 PM EDT SUN JUL 15 2012 .SYNOPSIS... AN UPPER LEVEL DISTURBANCE WILL CONTINUE TO WORK THROUGH THE AREA THIS EVENING KEEPING SHOWERS AND THUNDERSTORMS ACROSS THE REGION. SHOWERS AND THUNDERSTORMS WILL STAY IN THE FORECAST FOR PARTS OF THE AREA TO START THE WORK WEEK AS MOISTURE WORKS NORTH INTO THE AREA. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... ISOLATED TO SCATTERED THUNDERSTORM ACTIVITY WILL CONTINUE OVER THE NEXT COUPLE OF HOURS BEFORE DECREASING ACROSS THE AREA WITH SUNSET. MADE ONLY MINOR ADJUSTMENT TO TEMPERATURES FOR THE OVERNIGHT TO ADJUST FOR CURRENT TRENDS. WENT CLOSE TO GUIDANCE FOR LOW TEMPERATURES OVERNIGHT. NORTHERN PORTIONS OF THE FA WILL BEGIN TO CLEAR OUT LATER DURING THE OVERNIGHT AND SOME FOG FORMATION WILL BE POSSIBLE. FOG DOES NOT LOOK LIKE IT WILL BE DENSE ENOUGH TO PUT IN THE FORECAST AT THIS AND THEREFORE LEFT FOG OUT CURRENTLY FOR THE OVERNIGHT. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... MOISTURE WILL WORK UP INTO SOUTHERN PORTIONS OF THE FA FOR MONDAY DURING THE DAY BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS TO NORTHERN KENTUCKY...SOUTHERN OHIO...AND SE INDIANA. THE REST OF THE AREA WILL REMAIN DRY ON MONDAY. WITH LESS CLOUD COVER AND PRECIPITATION ACROSS THE AREA EXPECT TEMPERATURES TO BE SLIGHTLY WARMER THAN SUNDAY. WENT WITH HIGHS IN THE UPPER 80S TO THE LOWER 90S WITH THE LOWEST TEMPERATURES ACROSS SOUTHERN PORTIONS OF THE FA WHERE MORE CLOUD COVER AND PRECIPITATION WILL BE PRESENT. PRECIPITATION WILL TAPER OFF DURING THE EVENING HOURS MONDAY NIGHT AND HIGH PRESSURE WILL BRIEFLY WORK INTO THE AREA. && .LONG TERM /TUESDAY THROUGH SUNDAY/... RISING UPPER HEIGHTS AND SOUTHWEST LOW LEVEL FLOW WILL RESULT IN TEMPERATURES AND DEW POINTS CONTINUING TO INCREASE TUESDAY WITH A WARM AND MUGGY TUESDAY NIGHT. HAVE LEANED TOWARDS WARMER GUIDANCE FOR TEMPERATURES BOTH PERIODS. A WEAK DISTURBANCE ROUNDING AN UPPER RIDGE WILL COMBINED WITH PEAK HEATING COULD RESULT IN SOME STORMS DEVELOPING TUESDAY AFTERNOON INTO THE EVENING. CHANCE OF STORMS WILL INCREASE HEADING INTO WEDNESDAY AS A COLD FRONT MOVES INTO THE AREA FROM THE NORTH. THE FRONT WILL SAG SOUTH WEDNESDAY NIGHT AND THURSDAY RESULTING IN A GOOD CHANCE OF SHOWERS AND THUNDERSTORMS NEAR AND AHEAD OF THE FRONT. THE FRONT WILL CLEAR THE FORECAST AREA BY THURSDAY EVENING WITH HIGH PRESSURE BUILDING IN THROUGH THE REST OF THE WEEK. THIS WILL USHER IN LESS HUMID AIR WITH TEMPERATURES CLOSER TO NORMAL. THE HIGH WILL MOVE OFF TO THE EAST ON SUNDAY AND THERE IS THE POSSIBILITY OF A SYSTEM APPROACHING FROM THE NORTHWEST. BUT QUITE A BIT OF UNCERTAINTY THAT FAR OUT IN TIME WHETHER THERE WILL MUCH OF A CHANCE OF RAIN ON SUNDAY. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... SCATTERED SHOWERS WITH A FEW THUNDERSTORMS WILL CONTINUE INTO THIS EVENING...MAINLY NEAR KDAY AND KILN. THIS ACTIVITY WILL DIMINISH BEFORE MIDNIGHT. SCATTERED CU WILL REMAIN ACROSS THE AREA OVERNIGHT TONIGHT. IT IS APPEARING LESS LIKELY NOW THAT A STRATUS DECK WILL DEVELOP OVERNIGHT TONIGHT. HAVE THEREFORE REMOVED THIS FEATURE FROM THE FORECAST. IN TURN HOWEVER...PLENTY OF SURFACE MOISTURE WILL COMBINE WITH RADIATIONAL COOLING UNDER MOSTLY CLEAR SKIES TO ALLOW FOR FOG/MIST TO DEVELOP ACROSS THE AREA. THIS SEEMS REASONABLE AS AREAS UPSTREAM ACROSS IL/IN LAST NIGHT EXPERIENCED SEVERAL HOURS OF MVFR VSBYS. THE BEST CHANCES FOR MORE DENSE FOG/MIST APPEARS TO BE ACROSS THE SOUTHERN TERMINALS. AFTER SUNRISE...VFR CONDITIONS ARE EXPECTED TO RETURN WITH SCATTERED CU LASTING THROUGHOUT THE DAY. OUTLOOK...THUNDERSTORMS POSSIBLE WEDNESDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. && SYNOPSIS...NOVAK NEAR TERM...NOVAK SHORT TERM...NOVAK LONG TERM... AVIATION...LATTO
