Area Forecast Discussion
National Weather Service Omaha/Valley NE
1145 PM CDT Wed Apr 25 2018

.SHORT TERM...(Tonight through Saturday)
Issued at 245 PM CDT Wed Apr 25 2018

Slowly eroding cloud layer was located over the south half of the
area at 19Z with a closed upper low over central KS. As this upper
low continues its slow track to the south clouds will clear from
north to south across southeast Nebraska and southwest Iowa into
the early evening. Mostly clear skies will prevail for most of
the overnight period before clouds increase again toward morning
in advance of another upper tough and cold front.

This system will track rapidly southeast across the area on
Thursday with a small chance of spotty showers. Winds, however,
will be the main feature in the weather on Thursday as they shift
to the northwest behind the front with gusts to around 30 mph.
High pressure then settles over the region Thursday night with
winds becoming light and variable and skies mostly clear. These
conditions may result in some patchy frost early Friday morning
for parts of the area, mainly in the north. Dry and mild weather
is in store for both Friday and Saturday as high pressure
dominates the weather pattern over the region. An extended period
of Spring-like conditions will finally make an appearance over the
weekend and continue into early next week.

.LONG TERM...(Saturday night through Wednesday)
Issued at 245 PM CDT Wed Apr 25 2018

A more active spring pattern is expected to develop through early
next week across the region.

Increasing moist south flow will develop across the plains region
on Sunday and continue into Monday as a strong upper trough over
the western CONUS begins to eject several shortwave troughs into
the central plains. This will bring a chance of thunderstorms to
the region Sunday night and again Monday night and Tuesday as a
cold front moves through the area. The front may stall near the
southeast Nebraska border Tuesday into Wednesday with an
additional chance of thunderstorms during that time. This may
result in some significant rains for areas near the stalled
frontal boundary.


.AVIATION...(For the 06Z TAFS through 06Z Thursday night)
Issued at 1135 PM CDT Wed Apr 25 2018

Generally expect VFR conditions through the period. Winds will be
mainly under 10 knots from the south or southwest overnight.
For KOFK winds will shift to northwest 14z to 16z then to the
north with some moderate gusts after the wind shift. This wind
shift will be a bit later at KLNK and KOMA, more early afternoon.
Spotty showers are possible, with isolated MVFR ceilings, but
chances are too low to mention at this time.
