NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 13, 3:28 PM EST, 47 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 428 PM EDT SAT JUN 13 2015 .SYNOPSIS... WITH UPPER LEVEL RIDGING REMAINING CENTERED OVER THE SOUTHEASTERN STATES...WARM AND MOIST AIR WILL REMAIN IN PLACE OVER THE OHIO VALLEY. OCCASIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO NEXT WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... IN A VERY WARM AND UNSTABLE AIR MASS...THUNDERSTORM DEVELOPMENT OVER A FEW SECTIONS OF THE FORECAST AREA HAS BEEN ESSENTIALLY UNINHIBITED SO FAR TODAY. THE MAIN FOCUS SO FAR HAS BEEN IN THE EASTERN CWA...BUT ADDITIONAL STORMS DEVELOPING OVER INDIANA ARE LIKELY TO HAE A BIGGER IMPACT ON THE NORTHWEST CWA OVER THE NEXT FEW HOURS AND INTO THE EVENING. INSTABILITY IS CERTAINLY IMPRESSIVE...UP TO 3000 J/KG OF SURFACE-BASED CAPE...AND UP TO 2000 J/KG OF MIXED-LAYER CAPE. WIND SHEAR IS NOT STRONG (15-20 KNOTS OF 0-6KM SHEAR)...AND PROPAGATION VECTORS HAVE SET UP IN A WAY TO SUPPORT GENERAL SLOW STORM MOTIONS. THIS ADDS UP TO A MARGINAL THREAT FOR SEVERE WEATHER...WITH THE ATMOSPHERE TOO WARM FOR MUCH HAIL...BUT AT LEAST SOMEWHAT SUPPORTIVE OF STRONG DOWNDRAFTS. THE THREAT FOR LOCALIZED HEAVY RAIN COULD REMAIN AN ISSUE...AS SEEN WITH THE STORMS OVER NORTHWESTERN FAIRFIELD COUNTY...WHICH CONTINUALLY BACK-BUILT WHILE ANCHORED TO AN EAST-WEST BOUNDARY IN SOUTHERN FRANKLIN COUNTY. OVERALL LARGE-SCALE FORCING IS WEAK...SO STORM ORGANIZATION WILL LIKELY BE DRIVEN ON THE CELL-BY-CELL OR CLUSTER-BY-CLUSTER LEVEL. HOWEVER...CURRENT TRENDS DEFINITELY INDICATE THAT THE NORTHERN HALF OF THE FORECAST AREA WILL BE THE MOST FAVORED FOR ADDITIONAL DEVELOPMENT. STORM COVERAGE IS EXPECTED TO BE MUCH LESS OVER THE SOUTHWESTERN THIRD OF THE FORECAST AREA...AND LOWER POPS WERE USED THERE. BY OVERNIGHT...STORMS SHOULD BE ON A DIMINISHING TREND JUST ABOUT EVERYWHERE. THERE ARE SOME INDICATIONS IN THE MODELS OF ANOTHER WAVE OF PRECIPITATION TRYING TO MOVE INTO THE AREA (MAINLY THE NORTHWEST CWA)...BUT THERE HAS BEEN A NOTED POSITIVE BIAS IN THE QPF FIELDS AT AROUND 12Z FOR SEVERAL DAYS NOW...AS THIS PATTERN HAS GENERALLY KEPT THINGS NOT QUITE THAT ACTIVE DURING THE DIURNAL MINIMUM PERIOD. POPS WILL THUS BE LIMITED TO THE CHANCE CATEGORY OVERNIGHT. THE WARM AND MOIST CONDITIONS WILL LEAD TO ANOTHER NIGHT OF WARM MIN TEMPS...WITH UPPER 60S TO LOWER 70S. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/... THERE WILL BE VERY LITTLE OVERALL CHANGE IN THE WEATHER PATTERN FROM SATURDAY INTO SUNDAY...WITH AN UPPER RIDGE REMAINING IN PLACE OVER THE SOUTHEASTERN STATES. THE NORTHERN OHIO VALLEY WILL BE FIRMLY POSITIONED IN THE UNSTABLE ARC OF CONVECTION THAT EXTENDS FROM THE NORTHWEST GULF COAST INTO THE MID-ATLANTIC STATES. THERE IS NO REASON TO MAKE ANY SIGNIFICANT CHANGES TO THE TEMPERATURE FORECAST...WITH PERSISTENCE BEING USED AS GUIDANCE...BUT SOME SLIGHT DOWNWARD ADJUSTMENTS IN THE NORTHWESTERN SECTIONS OF THE CWA (WHERE CLOUD COVER IS EXPECTED TO BE A LITTLE MORE PREVALENT ON SUNDAY). THIS ALLOWS HIGHS TO RANGE FROM THE MID 80S IN THE NORTHWEST TO UPPER 80S (NEAR 90) IN THE SOUTHEAST. MIN TEMPS ON SUNDAY NIGHT WILL BE SIMILAR TO SATURDAY NIGHT...WITH VALUES IN THE UPPER 60S TO LOWER 70S. THE CONVECTIVE FORECAST FOR SUNDAY IS AGAIN LIKELY TO BE DIURNALLY DRIVEN...WITH A LACK OF FOCUSED UPPER-LEVEL SUPPORT ON THE PERIPHERY OF THE RIDGE. THUS...INTERACTIONS AND MORPHOLOGIES WILL LIKELY BE DRIVEN AGAIN ON THE STORM-SCALE...WITH SOME ASSISTANCE FROM ANY LEFTOVER BOUNDARIES THAT SETTLE INTO THE REGION FROM CONVECTION OVER THE PREVIOUS 24 HOURS. THE ENVIRONMENT WILL BE A LITTLE DIFFERENT...WITH SLIGHTLY LESS INSTABILITY THAN SATURDAY (1200-1500 J/KG MLCAPE OR 1500-2000 J/KG SBCAPE)...BUT SLIGHTLY MORE SHEAR (30 KNOTS 0-3KM AND SOME VEERING WITH HEIGHT). SO...SOME INDIVIDUAL STORMS OR CLUSTERS MAY HAVE SOME ORGANIZATION...AND THERE WILL BE A RISK OF ISOLATED SEVERE WEATHER (PRIMARILY DAMAGING WIND). COMBINING THE COVERAGE/INSTABILITY/SHEAR FACTORS ALL TOGETHER...THE GREATEST SEVERE RISK APPEARS TO BE IN THE NORTHERN HALF OF THE FORECAST AREA. AS HAS BEEN TYPICAL...STORMS ARE AGAIN EXPECTED TO DIMINISH IN COVERAGE AND INTENSITY ON SUNDAY EVENING. && .LONG TERM /MONDAY THROUGH SATURDAY/... HAVE USED A BLEND OF THE NAM/ECMWF THROUGH WEDNESDAY. THEREAFTER...THE EXTENDED HAS BEEN HEAVILY WEIGHTED TOWARD WPC GUIDANCE. UPPER LEVEL RIDGE CENTERED OVER THE SOUTHEAST U.S. WILL SLOWLY BECOME SUPPRESSED THROUGH MID WEEK AS WEAK EMBEDDED DISTURBANCES ROTATE AROUND ITS PERIPHERY ACRS THE GREAT LAKES AND THE OHIO VALLEY. AT THE SAME TIME...THIS WILL ALLOW A WEAK FRONTAL BOUNDARY TO SLOWLY PUSH INTO THE REGION FROM THE NORTH. WILL KEEP THE THREAT FOR SHOWERS AND THUNDERSTORMS IN THE FORECAST. FOR THE REMAINDER OF THE EXTENDED...SURFACE BOUNDARY MAY LIFT BACK NORTH. IF THIS FRONT GETS BACK NORTH OF THE AREA...IT WILL MARK THE RETURN TO DISORGANIZED FORCING AND LARGELY DIURNAL CONVECTION. LOWS WILL REMAIN ABOVE NORMAL THROUGH THE PERIOD. HIGHS WILL DROP BACK CLOSER TO NORMAL WITH THE FRONTAL PASSAGE AND THEN SLOWLY WARM AFTER THE BOUNDARY RETREATS NORTH. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... MOSTLY VFR CONDITIONS THOUGH WITH VERY MOISTURE LADEN ENVIRONMENT...OCCASIONAL MVFR CEILINGS POSSIBLE. MVFR VSBYS POSSIBLE WITH THUNDERTORMS MAINLY NEAR/BEFORE 00Z...AS WELL AS POSSIBLE GUSTS TO 30-35KTS IN SOME STORMS. OVERALL PRECIPITATION COVERAGE WILL DECREASE AFTER 00Z. QUESTION FOR THE NORMAL MVFR VSBY LOCTIONS OF KLUK/KILN...CONFIDENCE IS LOW ATTM SO STUCK WITH HIGHER LEVEL MVFR VSBY POTENTIAL. NEAR/AFTER 18Z GREATER POTENTIAL FOR MORE THUNDERSTORM COVERAGE. OUTLOOK...THUNDERSTORMS WILL BE POSSIBLE AT TIMES THROUGH WEDNESDAY. WITH HIGH MOISTURE ENVIRONMENT...MVFR TO POSSIBLY EVEN IFR CIGS/VSBYS IN SOME STORMS. && .ILN WATCHES/WARNINGS/ADVISORIES...
