Area Forecast Discussion National Weather Service Wilmington OH 707 AM EDT MON JUL 18 2016 .SYNOPSIS... A cold front will move south through the Great Lakes today, and south of the Ohio River on Tuesday. High pressure will then build into the region for the mid part of the week, bringing drier weather and near seasonable temperatures. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... The first weather focus will be the propagation of an upstream MCS heading east/southeast into the forecast area this morning. All models have been experiencing trouble capturing this feature and subsequently where it will move to before it weakens by mid morning. Based on radar trends and the latest HRRR, the best chance for showers and thunderstorms will be across the northern two thirds of the CWFA as the pcpn moves east/southeast. It becomes more unclear across the southern third CWFA so have only kept a chance of showers and thunderstorms going through the morning hours. Locally heavy rain will be the main threat with the potential for localized flooding. For this afternoon, it is still unclear on what convective coverage will transpire in the wake of the MCS as it will be highly dependent on short term mesoscale features. The HRRR tries to bring a convectively induced MCV toward the tri- state region by afternoon. However, based on how poor all the high resolution/convective allowing models have done recently, do not have much confidence with this feature at this time. A weak cold front will be approaching the northern zones as well. So, for now, will just have 30 pops for the afternoon hours with the caveat that short term/mesoscale trends will have to be watched for the potential to raise pops if the need arises. The combination of low end moderate shear and MLCAPEs in the 2000-3000 J/KG range may produce a severe storm or two with large hail and damaging winds being the primary severe weather threats. Locally heavy rain could occur as well given pwats approaching 2 inches. Finally, the combination of highs in the upper 80s and dewpoints in the lower 70s will push heat index values into the mid and upper 90s. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY NIGHT/... The cold front will slowly move toward the Ohio River tonight. Convection looks to be isolated to scattered at best, with a diminishing trend in coverage as the front slips south. Skies will clear from the north. On Tuesday, the front should eventually pivot south and southwest, keeping the threat for additional showers/storms out of the area by afternoon. Skies will be partly to mostly sunny with drier air filtering in from the north. Surface high pressure will build in from the north Tuesday night and remain over the region on Wednesday. A mid level ridge will begin to poke northeast toward the lower Ohio Valley Wednesday night. Models suggest a s/wv may dive southeast on the periphery of this ridge. There continues to be low confidence as to whether this feature, along with increasing instability, will be close enough to bring a threat of showers/storms. As a result, will maintain a dry forecast. Temperatures will be near seasonal normals for Tuesday and Wednesday. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Mid and upper level ridging will build east northeast toward the southern Great Lakes region through the end of the work week before beginning to weaken over the weekend. Both the 12Z GFS and 12Z ECMWF are trying to show some mid level energy dropping down across the western Great Lakes on Thursday but weakening it as it pushes into the ridge axis. As a result, will maintain a dry forecast for now but depending on the timing of this and actual placement of the ridge, we may end up needing some lower chance pops across at least northern portions of our fa Thursday afternoon into Thursday night. Stronger mid level energy and an associated short wave will move down through the western Great Lakes Friday into Saturday. This will eventually help push a cold front south across our area over the weekend and lead to at least some lower chance pops toward the end of the long term period. Temperatures will slowly moderate through the end of the week as heights rise and the airmass modifies across our region. High temperatures by the end of the week will be into the lower 90s with heat indices potentially pushing up toward advisory criteria for Friday and possibly Saturday afternoon. && .AVIATION /11Z MONDAY THROUGH FRIDAY/... Thunderstorms moving through the area will gradually weaken over the next few hours, eventually dissipating by late morning. Until that happens, some brief MVFR/IFR conditions (with thunder) will be possible through the 11Z-14Z time frame. Winds are expected to remain somewhat variable as the precipitation moves through, but occasionally gusty. Quieter conditions are expected for the late morning and into the afternoon, with winds eventually becoming established again from the SW at around 10-20 knots. There is low confidence in the forecast for additional convection this afternoon and evening, but the potential seems slightly higher for Cincinnati than for points further to the north. However, VCTS/VCSH will be used until timing and placement for additional storms (if any) becomes more certain. Quiet conditions are expected tonight and into Tuesday morning, with VFR flight conditions and winds becoming calm. OUTLOOK...No significant weather expected. && .ILN WATCHES/WARNINGS/ADVISORIES...
