Area Forecast Discussion
National Weather Service Omaha/Valley NE
331 PM CDT Thu Aug 10 2017

.SHORT TERM...(Tonight through Sunday)
Issued at 307 PM CDT Thu Aug 10 2017

Upper shortwave trough over south central Nebraska and Central
Kansas has developed showers and embedded thunderstorms across
central Nebraska and Kansas. This activity will move eastward and
affect southeast Nebraska tonight.

Some patchy fog may develop overnight over northeast Nebraska and
northwest Iowa, which should diminish by mid morning Friday.

Area should be dry during the day Friday. On Friday night,
another weak shortwave trough in zonal westerly flow should bring
another chance of showers and thunderstorms across the area into

.LONG TERM...(Sunday night through Thursday)
Issued at 307 PM CDT Thu Aug 10 2017

Zonal flow with shortwave troughs moving across Southern Canada
and the Dakotas will allow for slight chances of showers and
thunderstorms across the area through the remainder of the week.

to lower 80s through Wednesday. Temperatures are forecast to warm
up to the mid 80s Thursday.


.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.
