000 FXUS63 KOAX 261729 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1229 PM CDT Wed Apr 26 2017 .SHORT TERM...(Today through Friday) Issued at 355 AM CDT Wed Apr 26 2017 After a little patchy morning drizzle, much of the day should be cloudy, cool and blustery. A tight pressure gradient over the area will begin to relax later this evening once surface high pressure ridge builds south out of the Dakotas. Main forecast concern centers around near or below freezing temperatures overnight as we slide a little deeper into the growing season. Some question remains as to how much cloud cover and wind we can keep in our northeastern counties, which could prevent much frost formation for this area. For simplicity and advanced notice to growers, have hoisted a frost advisory for the entire area late tonight into Thursday morning. Day shift may need to consider additional freeze headlines for our north if winds/clouds look to diminish more than currently forecast. Otherwise, a slow warm-up into the mid to upper 50s is expected Thursday as high pressure remains over the area. An area of showers will likely develop across central Nebraska late Thursday ahead of next approaching shortwave trough. These will continue to spread east through the day Friday before moving out Friday evening. .LONG TERM...(Friday night through Tuesday) Issued at 355 AM CDT Wed Apr 26 2017 Dry conditions will be short-lived with precipitation spreading north across the area by Saturday afternoon ahead of a deep closed low rounding the Four Corners region. Think a good portion of the early part of Saturday could be dry, with precipitation moving across the area by mid-late afternoon. Widespread precipitation is then expected throughout the remainder of the weekend ahead of the above mentioned low which slides northeast across eastern Nebraska and eventually into southern Minnesota. This puts our area within the deformation zone into Monday. Will continue to monitor temperature trends with this system, but for now have included a mention of ra/sn mix across our northern counties both Sunday and Monday mornings. System is still a ways out but both GFS and ECMWF drop about 0.50-1.00"+ QPF over much of the area. && .AVIATION...
