000 FXUS63 KOAX 232306 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 606 PM CDT Sun Apr 23 2017 .SHORT TERM...(Tonight through Wednesday) Issued at 245 PM CDT Sun Apr 23 2017 Pocket of warmer air was located across the central plains this afternoon with a warm front over the northern plains near the South Dakota North Dakota border. Significantly colder north of the warm front with temperatures in the 30s at 18z across North Dakota. This colder air is forecast to begin to spread south on Monday behind a cold front which models bring into eastern Nebraska by late afternoon before stalling out across the area through Monday night. Better forcing and moisture look to remain mainly north of the area on Monday as the front approaches but some sprinkles here and there not out of the question late Monday afternoon into the evening. A better chance of showers moves into the area late Monday night and becomes likely on Tuesday and Tuesday night as the stalled frontal boundary begins to become more active and push southeast into Kansas and Missouri with overrunning pattern developing north of the front as strong upper trough approaches the central plains. Parts of northeast Nebraska could see a mix of rain and snow for a time late Tuesday night and Wednesday morning before ending. Temperatures will be turning colder behind the front on Tuesday with north winds increasing to 10 to 20 mph and gusty. Northern parts of the area are expected to remain in the 40s on Tuesday and again Wednesday. The clouds and rain will hinder any freezing temperatures or frost Wednesday morning but pockets of freezing temperatures are possible Thursday morning in northern and western parts of the forecast area as clouds decrease and winds become light. .LONG TERM...(Wednesday night through Sunday) Issued at 245 PM CDT Sun Apr 23 2017 Pattern looks to remain cool and wet through much of the period beyond Wednesday night as a series of upper troughs track across the central plains. Most significant system currently indicated by models will impact much of the region over the weekend with widespread showers and thunderstorms. Some potential for snow is also indicated for parts of the western high plains region during this time. && .AVIATION...

(For the 00Z TAFS through 00Z Monday evening) Issued at 606 PM CDT Sun Apr 23 2017 Gusty south winds observed over eastern NE late this afternoon may diminish some this evening as the boundary layer begins to decouple. At the same time, a nocturnal low-level jet will strengthen across the region, contributing LLWS criteria being met at all TAF sites into Monday morning. Surface winds are expected to strengthen again by mid morning Monday ahead of a cold front which will move into eastern NE by Monday evening. VFR conditions will prevail with persistent, scattered to broken high-level clouds.
