(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. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
