NWS Wilmington, OH wrote its last area forecast discussion before the first event at Jun 14, 12:22 PM EST, 48 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington OH 122 PM EDT Wed Jun 14 2017 .SYNOPSIS... A warm and moist airmass will lead to an unsettled weather pattern through the weekend. A drier and cooler airmass will settle into the area early next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... An axis of shower and thunderstorm activity centered across the middle of the FA this morning will continue to slowly drift eastward through remainder of the morning hours. Although hi-res models /in particular the HRRR/ are showing a gradual weakening trend as the activity moves eastward, decided to up PoPs to likely category in the east as MCV will likely provide enough elevated forcing to maintain activity through at least the next several hours. In the wake of the MCV-enhanced activity this morning, do think there may be a brief break early/mid afternoon despite increasing SB instability. Subsidence on the back edge of the MCVs across Ohio and north-central IN should initially inhibit redevelopment in the early afternoon before the cap eventually erodes toward late afternoon/early evening. Did reintroduce likely PoPs late afternoon/evening as one or multiple complexes of showers and thunderstorms move back into the area. There is still some uncertainty as to how much these areas of thunderstorms will develop /and subsequently be maintained/ as they approach the FA. However, do think that with sufficient instability building through the afternoon that coverage will be widespread enough to justify likely PoPs, especially for western zones. With all activity through the near term period, main threat will be locally heavy rain, which may lead to localized flooding concerns. Additionally, there is the potential for a few strong to severe storms, mainly with later activity, with locally damaging winds being the primary threat. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/... The weak mid level ridge in place across the region will finally break down tonight into Thursday as a stronger short wave moves east across the southern Great Lakes. This will lead to a continued chance of thunderstorms into tonight and then an increasing chance through mid day Thursday as the short wave combines with a destabilizing airmass. This will lead to a continued threat for locally heavy rain and isolated damaging wind gusts during the day on Thursday. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... The long term will open up active again with showers and thunderstorms Thursday night. Convection will likely be ongoing and exiting east thanks to a departing mid-level shortwave. Behind the shortwave most of the area should actually see a break in the precipitation Friday as much drier air works in to the region. PWATs Friday afternoon now actually fall below 1.00". 1000/ 850 mb thicknesses are still around 1420 m though and with 850 mb temperatures 18 to 20 degrees C high temperatures around 90 degrees Friday looks likely. The break in the precipitation looks to be short lived though as the upper level low over Manitoba continues to push east and moves into Ontario. As this happens a series of upper level disturbances will wash over the area allowing PWATs to slowly rise again towards 1.50". Have backed PoPs off a bit for Saturday though as a weak upper level low will be located over the southeastern United States helping to keep the better moisture advection more towards Indiana. By Sunday another piece of energy will quickly move east towards Minnesota and then eject towards Ontario. As this occurs a surface cold front will dive southwards. Ahead of the front moisture will begin to pool with PWATs approaching 2.00". As this occurs forecast soundings will destabilize with CAPE values moving over 1000 J/kg. Given the RRQ, moisture values, and instability showers and thunderstorms look likely Sunday evening. The timing of the cold front remains rather good with both the GFS and ECMWF having the front around I-71 late Sunday early Monday. The CMC is much slower with the front but have discounted this solution at this time. Monday into Tuesday surface high pressure will build into the region with 850 mb temperatures falling towards 10 degrees C. Dewpoints will also fall into the upper 50s allowing for a refreshing break from the humid air. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Areas of SHRA/TS will continue to move through the area for the first part of the TAF period. Brief MVFR or even IFR VSBYs are expected in some of the heaviest activity, although pinpointing such timing and location for each of the terminals poses quite a challenge. Have handled expected reductions/lowering in VSBY and CIGs with TEMPOs for now, but will likely need to adjust individually as activity evolves through the period. Winds will generally be out of the southwest, but given various storm-generated outflows and boundaries, periodic directional changes will be possible. Some brief gusts to 25kts are possible with heaviest TSRA. Although scattered SHRA/TS is expected to be on a weakening trend past 00z, still do think there may be some isolated activity lingering through the overnight hours. Have handled this potential with a VCTS for now, but adjustments will likely be needed as radar trends evolve during the evening hours. Hi- res models have been struggling quite a bit with development and progression of activity thus far today, so confidence on any one solution/evolution is low at this time. A downward trend in SHRA/TS will likely develop towards 12z before scattered diurnally-enhanced activity likely redevelops towards the end of the TAF period. Have included in the 30-hr KCVG TAF, but have omitted for other sites for now due to lack of confidence on exact timing. OUTLOOK...Thunderstorms possible through Thursday and then again Saturday into Sunday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None.
