Primarily diurnally driven convection through today. Cold frontal passage Tuesday with strong to severe storms. Drier airmass settles in for the rest of the week and holiday weekend. && .NEAR TERM /THROUGH TUESDAY/... As of 1228 PM Monday... Showers and storms will ramp up again this afternoon, in the humid/unstable environment, and as a shortwave crosses the Ohio Valley region. Widespread severe is not anticipated, but there is a continued downburst/damaging wind threat, along with a continued threat for localized flash flooding, as overall steering flow remains around 15kts or less and PWATs remain anomalously high. SPC has much of the area highlighted in a marginal risk today for the downburst potential. The bulk of the convection should wane somewhat overnight, however, another shortwave, and surface cold front will be approaching from the west by early Tuesday, with an increase in shower and storm coverage. An isolated strong to severe storm is possible owing to a slight uptick in shear, with damaging winds the primary threat. The cold front will arrive Tuesday afternoon/evening and should be east of the area by Wednesday morning. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... As of 1228 PM Monday... Cold front should generally be to the east of the area by Wednesday morning or early afternoon. A few showers or storms are still possible Wednesday from passing weak disturbances, but most areas should be dry. A secondary front crosses the area Thursday. Once again, an isolated shower or storm is possible, but for the most part, the area should be dry, and overall less humid than as of late. && .LONG TERM /FRIDAY THROUGH SUNDAY/... As of 1228 PM Monday... Increasing temperatures and humidity look to round out the extended as upper heights build across the area. Showers and thunderstorms will also be on the increase over the weekend, mainly diurnal in nature. Ridge looks to break down somewhat towards the end of the extended period, as a disturbance moves across the north. && .AVIATION /17Z MONDAY THROUGH FRIDAY/...-- Changed Discussion --As of 110 PM Monday... Scattered convection is developing across the area, with brief IFR conditions, and a potential for strong/erratic gusty winds. Most of the convection will dissipate after 02Z, however, isolated showers/storms will continue to be possible overnight. Patchy MVFR or worse fog will be possible overnight in areas that receive rain this afternoon. As we move into Tuesday, a cold front will move towards the area. This will bring a renewed threat of showers and storms to the area, with IFR or worse restrictions in vicinity of storms, and the potential for strong/gusty winds. In addition, widespread MVFR ceilings are expected to take hold across the area, particularly after 09Z and linger for much of the remainder of the TAF period. Bulk of convective activity on Tuesday can be expected to develop after 15-18Z and beyond. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing of thunderstorm activity may vary from forecast. Areas of fog may be worse tonight than currently forecast in spots that receive rain.
