000 FXUS63 KOAX 171059 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 559 AM CDT Tue Oct 17 2017 .SHORT TERM...(Today through Thursday) Issued at 331 AM CDT Tue Oct 17 2017 Dry/warm fall weather will continue with rain/thunderstorm chances by early in the weekend. Continued weak west/northwest flow aloft will continue today with a weak shortwave progged to slide overhead this afternoon. With little moisture to work with, this should pass by quietly. Otherwise, weaker surface winds expected today as compared to Monday. Lack of deeper mixing should keep highs fairly close to what they were Monday. A weak cold front will move through the area on Wednesday before high pressure over the Dakotas moves into the area for Thursday. The front will come through dry with decent mixing ahead of the boundary, boosting temperatures into the mid 70s. .LONG TERM...(Thursday night through Monday) Issued at 331 AM CDT Tue Oct 17 2017 By Thursday night, southerly low-level flow will bring moisture back into the region ahead of an approaching negatively tilted trough over the southwestern US. Surface dewpoints are progged to reach the mid to upper 60s by Saturday. This trough tends to weaken as it slides northeast into late Friday however a stronger trough will quickly drift east out of the Pacific Northwest and into the northern High Plains by early Saturday. At the surface, associated frontal boundary will extend from the eastern Dakotas southwestward into low pressure over northwest Kansas. A strengthening low-level jet overnight Friday into Saturday could aid in nocturnal thunderstorms over the area. Thunderstorms should become more widespread through the day Saturday as the strong front dives southeast across the forecast area. System moves out by Sunday with the remainder of the forecast looking dry. && .AVIATION...
