Area Forecast Discussion
National Weather Service Omaha/Valley NE
255 PM CDT Tue Apr 25 2017

.SHORT TERM...(Tonight through Friday)
Issued at 250 PM CDT Tue Apr 25 2017

Cool temperatures will prevail through the period with rain ending
this evening and returning again Thursday night and Friday.

Surface cold front extended from north central Iowa across extreme
southeast Nebraska into south central Kansas at 19Z. Areal
coverage of showers over northeast Nebraska had diminished
considerably from this morning with trend of patchy light showers
expected to continue into the evening over the area as weak upper
waves move across and the cold front pushes further southeast
into central Missouri.

Latest models then continue to move the rain north and south of
the area after midnight with drier air moving in behind the
front. Wednesday will be dry but quite cool across eastern
Nebraska and western Iowa with cloudy and breezy conditions
through much of the day. Some clearing is then expected to
develop Wednesday night as weak ridging moves over the area. The
clearing and light winds will bring the potential for frost
early Thursday morning to much of the forecast area.

Clouds increase again during the day Thursday as the next upper
wave moves into the region with rain chances increasing by
Thursday night and remaining across the area on Friday as the wave
lifts north. Widespread rain is expected to develop across the
area on Saturday and continue into Monday morning as this system
moves through the region. Northern and western parts of the area
could see a mix of rain and snow early Sunday morning

.LONG TERM...(Friday night through Tuesday)
Issued at 250 PM CDT Tue Apr 25 2017

Pattern remains cool and wet through the weekend as a strong upper
low develops over the southern Rockies and lifts toward the lower
Missouri Valley. Widespread rain is expected to develop across
the area on Saturday and continue into Monday morning as this
system moves through the region. Northern and western parts of the
area could even see a mix of rain and snow for a time on Sunday.
Warmer air then makes a rapid return early next week with highs
approaching 70 by Tuesday.

.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)
Issued at 1237 PM CDT Tue Apr 25 2017

IFR to low MVFR cigs will overspread all eastern Nebraska TAF
sites between 18Z and 00Z, and continue through most of the TAF
period. Cigs should generally average FL008 to FL015 with north
winds 15 to 20kt. Scattered showers in northeast Nebraska will
initially dissipate early in the TAF period, then redevelop by 00Z
and continue through about 06Z. Southeast development toward KOMA
and KLNK is in question, and would expect only isolated showers
at these sites.
