No significant changes. && .KEY MESSAGES... 1) Additional showers and thunderstorms are expected into tonight, with some risk for heavy rainfall. 2) Another chance for showers and thunderstorms will be possible on Saturday. && .DISCUSSION... KEY MESSAGE 1) A mid level short wave will move east across the mid Ohio Valley tonight as a frontal boundary sags slowly south across the region. The airmass across our area has begun to slowly recover with MLCapes now back up to around 1000 J/KG. This will allow for showers and some embedded thunderstorms to overspread our area through the rest of the afternoon and into this evening. Will likely see some additional showers then linger through much of the night across mainly our southeast as the boundary continues to push slowly south. The overall severe threat will be limited by the marginal instability, but increasing mid level flow through late afternoon could allow for a few stronger to possibly severe storms if we are able to destabilize a bit more. The main threat would be gusty winds into early this evening. PWs ahead of the front will remain in excess of 2 inches tonight. Thus, locally heavy rainfall will remain possible along with the potential for flooding in areas where storms are able to train. The best chance for this appears to be across southeast portions of our area into tonight. KEY MESSAGE 2) The frontal boundary will push slowly south on Friday before lifting back to the north on Saturday ahead of an approaching mid level short wave. This will lead to another chance of showers and thunderstorms for the first half of the weekend. && .AVIATION /00Z FRIDAY THROUGH TUESDAY/... Showers associated with a mid level shortwave were developing in a region of marginal instability ahead of east-west oriented surface cold front. Expect this pcpn to continue to shift east early this evening and decrease in coverage. As the front sags into the area additional development is expected to be south of the TAF sites overnight. Some of the model solutions continue to suggest the potential for low clouds and fog later tonight. This fits the conceptual model of a moist environment with low level northeast flow in the wake of the front. Therefore, have continued MVFR to IFR conditions later tonight into Friday morning. Ceilings and visibilities will slowly improve through late Friday morning with VFR conditions returning during the afternoon. Southwest-west winds at less than 10 kts veer to the northwest and then northeast overnight. Northeast winds at 5 to 8 kts on Friday become east and then southeast during the afternoon. OUTLOOK...Additional thunderstorms possible on Saturday. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...None. KY...None. IN...None. && $$ DISCUSSION...JGL AVIATION...AR
