Area Forecast Discussion National Weather Service Wilmington OH 412 PM EDT THU JUL 14 2016 .SYNOPSIS... A disturbance traveling along a westerly flow aloft will interact with an unstable airmass ahead of a cold front, producing scattered showers and thunderstorms through early tonight. A low chance for showers and thunderstorms will persist on Friday when the cold front will be crossing the forecast area. Drier weather is expected Saturday with high pressure centered over the Great Lakes. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... Surface analysis shows a cold front over Illinois, with the ILN area under a humid and unstable airmass ahead of the front. CAPE fields show a more unstable regime along and south of the Ohio River, with a relatively stable area in the middle of the FA, and another area of lesser instability pushing in from the west. Stronger thunderstorms appear to be confined to the far southeast in the deeper moisture and instability, with showers and a few thunderstorms developing in shallower convection moving back in from the west. Going with pops as high as likely in the far southeast, diminishing to chance and slight chance farther north in the weaker instability and shallower moisture. In addition to a slight risk for severe thunderstorms in the far southeast containing damaging winds, will be monitoring for training cells as movement of the system is rather gradual and localized flooding could develop. Convection will exhibit a diminishing trend after sunset with loss of daytime heating, especially as low temperatures drop toward lows in the upper 60s later tonight. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Cold front will be pushing across the area on Friday. Though instability will be marginal and forcing rather weak, a few showers and thunderstorms may develop in residual moisture and CAPE near the front. A low chance for showers and thunderstorms will linger in southern locations Friday night as the front works slowly southeast. Highs are forecast to be in the mid to upper 80s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... High pressure will be working into the area for Saturday and into Saturday night. This will allow for dry conditions across the region. Northerly flow on Saturday will allow for the coolest day of the long term with high temperatures in the low 80s. Southerly flow will develop on Sunday allowing for an increase in temperatures. Dry conditions will continue through Sunday night. Unsettled weather is expected during the Monday to Tuesday time frame. A system is expected to drop into the region mainly Monday afternoon into Monday night. There is the potential that some of these storms may be severe with damaging winds the primary threat. Some residual thunderstorm activity will be possible on Tuesday as an upper level disturbance moves through. Models are hinting at a couple of weak disturbances after the Tuesday time period, however with only weak signals and model variability decided to leave Wednesday and Thursday dry at this time. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... Scattered showers and a few thunderstorms have developed across southeast Indiana in the last hour or so. Hi res models are suggesting this will continue to fill in through the afternoon hours as we further destabilize. As a result, will allow for a VCTS into early evening at all of the TAF sites and try to hit the more favorable time with a tempo -shra/-tsra. Expect primarily VFR conditions, but some mvfr to locally ifr conditions will be possible with any storm. As we lose the diurnal heating, pcpn should taper off through the evening hours with at least some partial clearing overnight. Depending on how much pcpn actually falls, we could see some mvfr vsbys develop later tonight into early Friday morning. Would think the best chance for this would be at the southern TAF sites so will include a tempo group for KCVG/KLUK. VFR conditions are then expected through the remainder of the TAF period as high pressure begins to build down from the northwest.
