Area forecast discussion, Aug 4, 3:01 PM CDT, 1 hour 20 minutes before
Area Forecast Discussion National Weather Service Omaha/Valley NE 301 PM CDT THU AUG 4 2016 .SHORT TERM...(tonight through Sunday) Issued at 300 PM CDT Thu Aug 4 2016 Surface cold front was in the process of moving through the area this afternoon and at 19z extended from northwest Iowa through east central Nebraska into southwest Kansas. Isolated storms had developed ahead of the front from southeast Nebraska into southwest and central Iowa with another band of storms behind the front from southeast South Dakota into southern Minnesota. Short range CAM models continue to favor development ahead of the front for the remainder of the afternoon into the evening as the front moves southeast into southern Kansas and central Missouri overnight, then stalling out in that area on Friday. Front remains stalled to the south of the forecast area Friday night into Sunday with potential still indicated for prolonged heavy rain event for the southern half of Nebraska into southwest Iowa as overrunning pattern develops under near zonal steering flow aloft. Outside of the increasing chance of rain, cooler and less humid conditions behind the front will be the other major feature for the area during this time. .LONG TERM...(Sunday night through Thursday) Issued at 300 PM CDT Thu Aug 4 2016 Warmer temperatures look to return in the extended period as broad area of high pressure aloft expands across much of the south half of the nation. Still some chance of periodic thunderstorms during this time as monsoonal moisture is pulled into the circulation. Both the GFS and ECMWF also develop a closed low over the Gulf of Mexico off the Florida Panhandle for some tropical action. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 141 PM CDT Thu Aug 4 2016 Some mvfr cigs possible with showers/thunderstorms and mentionED vcsh/vcts at KOMA/KLNK this afternoon and could see thunder at KLNK this afternoon. The storms north of KOFK are forecast to weaken so only included a vcsh there toward evening. WindS south/west/northwest and variable with the brisk winds 10-20KT behind the front. generally VFR after 01z and kept precipitation south of the taf sites after this period. && .OAX Watches/Warnings/Advisories...
