NWS Wilmington, OH wrote its last area forecast discussion before the first event at Sep 8, 7:00 PM EST, 1 hour 35 minutes earlier.
Area Forecast Discussion National Weather Service Wilmington OH 800 PM EDT THU SEP 8 2016 .SYNOPSIS... Increasing moisture and a series of upper level disturbances will bring a chance of showers and thunderstorms to the Ohio Valley as a front move into the region from the north. Chances for showers and thunderstorms will remain in place through Saturday, when a cold front moves through, bringing drier conditions on Sunday and into next week. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Mid level shortwave moving through the Great Lakes Will flatten out the northern portion of the ridge. Surface cold front will drop south into ILN/s northern counties overnight and stall out e-w parallel to the westerlies. In moist southwesterly flow PW/s will increase to 2.2 to 2.4 inches by Friday morning. Weak axis of 8H convergence to drop south and weaken during this evening. This will allow scattered showers and thunderstorms across the far northwest to weaken as it moves south across ILN/s FA. In this very moist environment, some of the storms may contain locally heavy rain. Given moderate instability in place early this evening, a few of the stronger storms could produce strong to severe winds. Lows will range from the upper 60s northwest to the lower 70s southeast. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/... Shortwave to lift northeast in moist southwesterly flow Friday. Numerical models generally consistent with this s/w inducing a weak surface wave that tracks ne from the Mid MS Vly into the Great Lakes Friday/Friday night. This will allow the stalled front to lift north as a warm front. Best pops look to be focused over the west-northwest Friday afternoon/Friday evening, where more favorable instability and forcing coincides. Have mention of likely pops over this location. Threat for local heavy rain will continue with max PW axis in excess of 2 inches lifting north across ILN/s FA Friday night. Temperatures to remain a little above normal Friday, with highs from the lower 80s northwest to the mid 80s southeast. Lows will be muggy Friday night in the warm sector with readings around 70. Progressive mid level shortwave to move through the Great Lakes Saturday. Deepening surface low to track from the Upper MS VLY through the Great Lakes. Trailing the sfc low, a cold front will sweep east through ILN/s FA Saturday afternoon. Expect storms to develop in the axis of moderate instability that develops along and ahead of this front. Given wind flow, the potential exists for storms to organize into line segments with damaging winds being a threat. Have increased pops to likely with this fropa. Temperatures will show a good gradient with highs from near 80 northwest to the upper 80s southeast. In the wake of this front, surface high pressure builds in from the west Saturday night. Precipitation to come to an end Saturday evening with diminishing cloud overnight. Cooler and drier air advects in with lows in the mid and upper 50s. && .LONG TERM /SUNDAY THROUGH THURSDAY/... Period begins with the region in a post frontal regime as high pressure builds east up the Ohio River Valley. Dry conditions will prevail through Tuesday, as the high will control the region's weather. Highs will be 70s on Sunday, then gradually warm to the 80s by Tuesday. Late Tuesday night into Wednesday, a cdfnt will drop into the area as a H5 s/w swings across the Great Lakes. There will be a chance of thunderstorms as the front pushes through. Highs Wednesday will be cooler, in the 70s, due to the rain chances. Another high pressure system will build in Wednesday night into Thursday. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... Additional convection extending from the area southwest to near KPAH, where an upper level disturbance will ride along the weakening boundary which will slowly settle southward across the mid ohio valley. Kept VCSH in the area with some uncertainty with how much of the current convection over southern Indiana will hold together as it rides along the boundary. Kept IFR ceilings in the forecast to develop mainly at kday/klck/kcmh north of the boundary and spread southward to kiln/kcvg/kluk as the boundary settles southward in the 12-18z timeframe. By 18z Friday...the stalled frontal boundary will begin to lift north as a warm front. IFR ceilings as a mid level trough digs/MVFR visibilities will improve with daytime heating...though scattered storms will develop in the afternoon with most of the taf locations will be in the warm sector between the northward progressing warmfront and ahead of the strong cold front to push through the area on Saturday.
