&& .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1235 PM CDT Thu Aug 10 2017 VFR conditions are indicated through the TAF cycle. Ceilings should remain above 5000ft at all sites, but the possible exception could be at KLNK if it is affected by showers/storms in the late afternoon/early evening. Current forecast primarily keeps showers/isolated storms south of KLNK, thus no mention in the TAF. Also kept visibility unrestricted at all sites, but with light winds, cannot rule out brief MVFR visibility at all sites close to dawn. In short, the TAF set reflects the optimistic outcome projected by the model blend, but other less optimistic scenarios are possible. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
