000 FXUS63 KOAX 181317 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 717 AM CST Thu Jan 18 2018 .SHORT TERM...(Today through Saturday) Issued at 300 AM CST Thu Jan 18 2018 A period of pleasant weather will prevail through the short term with temperatures warming to above seasonal normals each day. Upper ridge axis stretched from the desert southwest across the central Rockies and into the Canadian prairies at 08Z with a developing surface trough over the western high plains. As the upper ridge drifts east and flattens over the region through Friday, significantly warmer air will overspread the central plains with west to southwest flow at the surface. Parts of the area with deeper snow cover will see a lag in the return of warmer temperatures today but nonetheless, still climb above freezing with even greater warming on Friday as temperatures climb into the 40s and 50s across the area. Slightly cooler air will drop into the area on Saturday as a frontal boundary begins to develop over the region ahead of low pressure organizing over Colorado in advance of a strong shortwave trough approaching the southern Rockies. This system will bring widespread winter weather from the central plains into the upper Midwest from Sunday into early next week. .LONG TERM...(Saturday night through Wednesday) Issued at 300 AM CST Thu Jan 18 2018 As mentioned above, a widespread area of winter weather is expected to track across the region from late Saturday night into Tuesday with the potential for a significant winter storm system to develop. The exact track and timing of the system remains uncertain however due to differing model solutions. The GFS remains the faster of the models with the others showing a slower track into and across the region. Mixed precipitation is likely for the area initially on Sunday before changing over to all snow Sunday night with snow continuing into Monday. Strong north to northwest winds will also accompany this storm with the potential for near blizzard conditions in some areas by Monday morning. The storm should be winding down Monday night with seasonal temperatures for Tuesday and Wednesday. && .AVIATION...
