NWS Norman, OK wrote its last area forecast discussion before the first event at Aug 31, 2:19 PM CST, 21 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 319 PM CDT WED AUG 31 2016 .DISCUSSION... Scattered thunderstorms will continue. The persistent convection of recent days will be also supported tonight and tomorrow by a slow south moving shortwave, especially in western and northern Oklahoma. Although ongoing convection is not too widespread, the very efficient rainfall production and slow movement is creating some potential high water issues, so will be brief with this discussion. Precipitation chances will decrease for Friday and the weekend as the upper ridge builds more into the area with warmer temperatures expected again. && .PRELIMINARY POINT TEMPS/POPS...
