000 FXUS63 KOAX 231119 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 619 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...
