AREA FORECAST DISCUSSION National Weather Service Wilmington OH 337 PM EDT Sun Jul 14 2019 .SYNOPSIS... A weak frontal boundary meandering about the area will provide a focus for isolated storms today with increasing warmth and humidity through the first part of the workweek. Rain and storm chances will be on the increase Tuesday and Wednesday as the remnants of Barry move through the region. Heat and humidity will return towards the end of the week. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... The front, as of this writing, now stretches from approximately Wayne County, Indiana through Hocking County, Ohio and will continue to serve as a focus for isolated to scattered storm development through the early evening hours. The favored corridor will extend about 50 miles north and south of the front where satellite imagery shows a better development of Cu for many spots north of the Ohio River and near and just south of the I-70 corridor. With relatively robust instability but a lack of any notable bulk shear, updraft/downdraft interactions will be key in terms of determining exactly how well any storm is able to be maintained. The environment continues to suggest pulsy convection, with at least a non-zero threat for some gusty winds owing to strong DCAPE values in excess of 1000j/kg planted across most of the ILN FA. However, the instances of storm development robust enough to generate any sort of elevated core is likely to be spotty at best, so do think that any threat for gusty and/or damaging winds will be rather limited (but cannot rule it out completely). The spotty convection should be primarily diurnally-driven and is expected to wane past sunset, leaving most (if not all) of the area dry for the overnight period tonight -- with a mix of clouds lingering through Monday morning. Temperatures this afternoon have once again topped out near/around the 90-degree mark area-wide, with the lone exception being from west-central Ohio through central Ohio where temperatures have been held several degrees cooler (mid 80s) -- owing to being on the northern side of the frontal boundary. Lows tonight will be rather slow to drop off, especially as higher dewpoints begin to creep north again late tonight as the front begins to retreat back north/east. Lows will range from the mid/upper 60s in central Ohio to around 70 degrees in the Tri-State area. && .SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/... Monday will be off to a warm and muggy start across much of the Ohio Valley -- with an early spotty shower possible in the far northern parts of the local area. By Monday afternoon, shower/storm potential will once again be on the increase across much of the area -- especially with the arrival of various pieces of midlevel energy courtesy of the remnants of Barry further to the southwest. These pockets of midlevel energy will become detached from the main remnant circulation and propagate northeast toward the Ohio Valley beginning Monday afternoon. With better upper level forcing for ascent arriving amidst a seasonably unstable environment, expect that isolated to scattered convection will once again develop Monday afternoon. This will likely be initially focused near and south of the Ohio River before better coverage spreads north/northeast through the day. Coverage of activity may in fact be a bit more widespread by Monday afternoon than will be the case at any time today -- owing to better mid/upper level support for convective enhancement and maintenance. Highs will once again top out a degree or two either side of the 90-degree mark Monday afternoon, with dewpoints hovering near 70 degrees by the afternoon. This will likely occur despite an overall trend toward cloudier conditions -- especially with the arrival of thicker cirrus from remnant Barry as early as Monday morning. Activity should once again decrease in coverage somewhat Monday evening, but may be met later in the overnight period by an increase in showers/storms across near/west of I-75 as another round of midlevel energy begins to pivot northeast through the region. Lows Monday night will bottom out in the lower 70s -- with mainly dry conditions favored across central and eastern portions of the ILN FA. && .LONG TERM /TUESDAY THROUGH SUNDAY/... The remnants of Barry will slowly lift northeast across the Ohio Valley Tuesday through Wednesday. An initial axis of energy associated with the remnants will lift northeast into our area through the day on Tuesday. This will combine with some decent instabilities and marginal shear to produce scattered shower and thunderstorm activity and perhaps a marginal severe threat. Highs on Tuesday will be in the mid to upper 80s. The main pcpn associated with the remnants will work its way east across our area later Tuesday night and through the day on Wednesday. This will likely help keep temperatures down a bit on Wednesday with highs in the low to mid 80s. Some embedded thunderstorms will also be possible along with locally heavy rainfall given the tropical airmass. Models continue to vary somewhat on how much the ridging will build into the region later in the week and into the weekend. The general trend though is for mid and upper level ridging to build east into the Ohio Valley through the weekend. This would keep our region in a hot and humid airmass and on the periphery of some of the stronger mid level energy moving over the ridge, more across the Great Lakes region. Will therefore keep any pops in just the slight chance category at best through the remainder of the long term period. Highs will be mainly in the lower 90s and with a humid airmass in place, afternoon heat indices in the upper 90s to lower 100s will be possible each day. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... VFR conditions continue across the region with some diurnally- driven VFR Cu beginning to sprout with the heating of the day. Still anticipate some isolated to scattered SHRA/TS development by mid-afternoon, especially for KDAY and KILN, with northeastern sites of KCMH/KLCK and southwestern terminals of KCVG/KLUK seeing a better chance at remaining mainly dry through Monday morning. Certainly some spotty SHRA/TS cannot be completely ruled out anywhere this afternoon, but the favored corridor for activity seems to be lining up better for KDAY and KILN to be impacted (or at least have activity nearby), so maintained the VC for these sites. Isolated SHRA/TS will wane after sunset but could linger for a few hours depending on the coverage and intensity of activity that develop earlier in the afternoon/early evening. Nevertheless, went with a dry fcst everywhere after 02z with a mix of clouds lingering through the overnight period. Some thicker cirrus will be overspreading the Ohio Valley from the south late tonight. However, even with this being said, some brief MVFR VSBYs cannot be completely ruled out again at KLUK with winds going calm after sunset -- but think that potential is low enough as to not include in the TAF at this time. If a terminal does receive rainfall courtesy of a SHRA/TS this afternoon, that may increase the chances for a bit of BR development toward 12z Monday. Dry conditions are expected through the first part of Monday morning before scattered SHRA/TS develop initially southwest of the local area and move northeast during the daytime period. Included a VC at KCVG and KLUK past 16z to account for this potential. Activity may be a bit more widespread on Monday than is the case today, but think that greatest potential for pcpn will hold off until after 18z for the other sites. Despite a frontal boundary bisecting the area, with KCMH and KLCK seeing more northerly winds and KCVG and KLUK having winds out of the southwest, winds will generally be 5kts or less everywhere -- with calm winds likely again tonight.
