.AVIATION...(For the 06Z TAFS through 06Z Sunday night)
Issued at 1110 PM CDT Sat Jun 17 2017

Latest satellite imagery shows mostly clear skies north of the
Interstate 80 corridor. Elsewhere, satellite and surface plot
shows mostly cloudy skies with predominantly high-end VFR
ceilings (greater than 8 kft). Local radar display shows isolated
showers and thunderstorms moving eastward south of I-80 with
infrequent lightning. KIML recorded a hundredth over the last
hour with measurable precipitation occurring. Current thinking is
this activity will taper off gradually over the next few hours.

Rest of tonight, mostly clear skies will prevail outside of
lingering clouds across southwest NEB (mainly mid-level clouds).
Northwest winds will increase tomorrow morning with modest breezes
continuing during the day. Strongest winds over north central NEB
with peak gusts to 20 MPH. Winds should lessen in the early
evening. Also, sky cover will increase across western NEB during
the evening hours tomorrow though ceilings will remain VFR.
