Area Forecast Discussion
National Weather Service Omaha/Valley NE
332 AM CDT Fri Mar 23 2018

.SHORT TERM...(Today through Sunday)
Issued at 330 AM CDT Fri Mar 23 2018

To begin this forecast the central United States is under the
influence of large-scale ridging with troughing along the west and
east coasts. The latest radar returns show elevated echoes across
central and northeast Nebraska as of 8z. Some light rain was noted
at KHDE/KBBW/KICR. This light rain, which for the most part isn`t
reaching the ground, is the result of modest warm-air advection
underneath the main ridge axis. This area of light rain will shift
east throughout the morning and will become a significant
precipitation producer later in the day in central and eastern
Iowa. Back over our area, a shortwave is forecast to dig into the
backside of the upper ridge this evening, resulting in a more
substantial rain/thunder potential. The latest forecast shows a
quarter to a half inch of rain is expected across the County
Warning Area. Embedded thunder, along with a hail threat, will be
focused along and south of the Platte River and into far
southwest Iowa where elevated instability is more prevalent.

Mid-level ridging returns temporarily late Saturday night before
southwest flow aloft begins, signaling the beginning of a fairly
cloudy and unsettled weather pattern.

.LONG TERM...(Sunday night through Thursday)
Issued at 330 AM CDT Fri Mar 23 2018

This unsettled pattern, largely the result of large-scale
troughing, will persist through Tuesday night. We will likely deal
with another chance at thunderstorms on Monday afternoon and
evening as a warm front lifts north along the Nebraska/Kansas
border. This should also allow for some decent temperature
recovery with highs reaching in the upper 60s south to around 50
in the north.

The rest of the week plan on highs in the low 50s and overnight
lows near to just above freezing. As of now there are no
precipitation events expected as our area remains in the wake of
the previous trough.


.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1150 PM CDT Thu Mar 22 2018

VFR conditions will continue overnight, but MVFR cigs are forecast
to spread over all eastern Nebraska TAF sites by or shortly after
18Z. Areas of drizzle then showers will develop during the
afternoon and continue through the end of the TAF period while
cigs gradually lower to IFR by 00Z or so. An isolated thunderstorm
is possible near KLNK and KOMA between 00Z and 06Z.
