Area Forecast Discussion National Weather Service Omaha/Valley NE 1139 PM CDT Fri Aug 3 2018 .SHORT TERM...(Tonight through Monday) Issued at 255 PM CDT Fri Aug 3 2018 Short wave ridge axis is centered over forecast area late this afternoon, but on the western horizon large scale upward forcing is increasing as short wave centered over Saskatchewan treks eastward. Several attendant lobes of the larger short will impact the forecast area tonight through Saturday. The stronger dynamics will be north, so most potent and sustained convection should focus across the Dakotas; however, low level jet of 45-50kt will provide low level focus and moisture advection that will allow at least scattered convection to persist across at least northeast Nebraska. Large scale wind profile sufficient to support severe convection. Lingering overnight convection expected at least Saturday morning, then mesoscale subsidence will diminish threat through perhaps mid-afternoon. Another disturbance likely will cause convection to redevelop late Saturday and Saturday evening across mainly southwest Iowa into southeast Nebraska. There again will be a lull, then another round of convection is expected Sunday. All activity looks to be fairly progressive, but after several rounds of potentially heavy rainfall, will have to monitor flash flood potential on Sunday into Monday. .LONG TERM...(Monday night through Friday) Issued at 255 PM CDT Fri Aug 3 2018 Flat, quasi-zonal flow transitions to a more meridional character during the long term portion of the forecast, with the bulk of the area under the influence of the anti-cyclonic shear side of the large scale trough to the east and ridge to the west by mid- to late week. Early in the long-term, remnant of surface boundary will be draped along of just south of the forecast area, thus expect some surface-based convection to impact extreme southeast Nebraska Tuesday. A threat of elevated convection continues into Tuesday night into Wednesday, as a weak disturbance zips southeast and provides some upglide 315-325K. Thereafter, the axis of the upper level ridge builds eastward enough to diminish precipitation chances. Temperatures appear seasonable for early August. Building ridge later in the week will allow temperatures to climb toward higher side of normal. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1136 PM CDT Fri Aug 3 2018 Showers and thunderstorms affecting all three TAF sites, ending from 11-15z from west to east. Non convective LLWS also at KOMA/KLNK through about 15z as well, with winds at 2000' from 200 around 45 knots. Once the rain chances move out, southerly gusty winds at 15 to 25 knots, with gusts diminishing by 05/00-02z. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.

Some of the storms could be strong to marginally severe in northeast Nebraska, northwest of a line from Albion to Wayne tonight. The is a small risk that a couple of storms could still be severe Saturday north of Interstate 80. The main concerns will be strong winds to 60 mph, but hail up to quarter size is possible as well. Flooding continues along the Missouri River above Lewis and Clark Lake. .DAYS TWO THROUGH SEVEN...Saturday night through Friday Additional thunderstorm chances remain in the forecast Saturday night through Monday night. Strong to marginally severe storms will again be possible north of Interstate 80 during the afternoon and evening hours Sunday. .SPOTTER INFORMATION STATEMENT... Spotter activation will probably not be needed tonight or Saturday, however spotters are still encouraged to report severe weather if it develops in your area. DeWald
