.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 1150 PM CST Fri Feb 24 2017

Latest satellite imagery and surface plot shows BKN-OVC high
clouds across western NEB with SCT high clouds over north central
NEB. VFR conditions currently prevail across much of the area
with the exception being in portions of the eastern NEB Panhandle.
There patchy fog is present based on obs and web cams and it`s
reducing visibility sub-one mile. Winds are light and variable to
calm in eastern NEB and far southwest NEB, elsewhere light
northwest winds are present. Main concerns this TAF package are
flight categories rest of tonight into tomorrow in western NEB.

Current thinking is patchy fog will remain a threat across the
eastern NEB Panhandle into the western Sandhills rest of tonight
into the early morning. Do not think fog will impact KVTN or KLBF
terminals at this time. Will continue to monitor the situation
and update as necessary.

Winds will continue to lessen rest of tonight across north
central NEB and the west of western NEB. Winds increase tomorrow
out of the west starting late morning/early afternoon to 9-12 kts
across the local forecast area.
