000 FXUS63 KOAX 181750 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1150 AM CST Wed Jan 18 2017 .SHORT TERM...(today through Friday) Issued at 300 AM CST Wed Jan 18 2017 Upper level pattern is expected to remain very active during both the short and long term as a series of systems track across the region in fast westerly flow. Clear skies covered most of the forecast area early this morning with extensive cloud cover located east and south of the area. Some patchy fog possible in a few locations through mid morning, mainly in southwest Iowa and portions of southeast Nebraska where winds are light to calm. Mainly sunny conditions are expected to develop during the morning but clouds will be on the increase late this afternoon and tonight as an upper level system lifts out of the southern Rockies and into the central plains region. This system then continues to intensify over the area on Thursday before lifting northeast toward the upper midwest and lower Great Lakes Thursday night and Friday. Another system follows quickly on the heels of the first on Friday, moving out of the central Rockies and over Kansas and Nebraska. Both of these systems will bring another prolonged period of cloudy and damp weather to the area with some chance of drizzle or light rain from Thursday morning through Friday. The one positive factor during this time is that temperatures will remain above normal, keeping the chance of freezing precipitation to a minimum. .LONG TERM...(Friday night through Tuesday) Issued at 300 AM CST Wed Jan 18 2017 There will be a better chance of rain Friday night into Saturday as the central Rockies system lifts north across the region toward the upper midwest. Temperatures are expected to still remain above normal during this time with rain again the primary precipitation type. Above normal temperatures continue through the weekend and into early next week with dry weather expected as the region is forecast to stay north of another strong fast moving system coming out of the southern Rockies and across the southern plains on Saturday and Sunday. Short wave ridging will move over the region on Monday in advance of yet another broad trough coming across the southern Rockies. this system will bring an increasing chance of rain or snow to the region on Tuesday as temperatures begin to trend a bit cooler. && .AVIATION...
