Area Forecast Discussion National Weather Service Tulsa OK 904 PM CDT Sun Jul 21 2019 ...UPDATE... .DISCUSSION... Currently monitoring a few clusters of strong/marginally-severe thunderstorms moving southeast across southeastern KS. Also watching more isolated convection to the west of Tulsa that has formed along a weak pre-frontal convergence line. Storm extrapolation along with recent HRRR output would put the best chances of storms across far northeast OK over the next several hours, and eventually into parts of northwest AR. It's possible that the stronger storms could produce gusty winds and perhaps some hail, although expect a weakening trend generally after midnight. Have made some near term adjustments to PoPs, otherwise forecast is in good shape. && .PRELIMINARY POINT TEMPS/POPS...
