NWS Norman, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 14, 3:02 PM CDT, 1 hour 20 minutes earlier.
Area forecast discussion, Jul 14, 3:02 PM CDT, 1 hour 20 minutes before
Area Forecast Discussion National Weather Service Norman OK 302 PM CDT Fri Jul 14 2017 .DISCUSSION... Convection has already developed along a weak surface boundary located approximately from Enid to Arnett in northwest Oklahoma. Additional isolated showers/storms were occurring over southern Oklahoma and western north Texas in a mildly unstable and very weakly-sheared environment. Most of this convection should diminish around sunset. Leftover weak boundaries should raise the chances of showers/storms tomorrow (Saturday) mainly from northwest to southeast Oklahoma. Again, higher chances of rain will be mainly in the afternoon. As the upper-level ridge builds back into the southern Plains early next week, rain chances will generally shut off, and temperatures will rise back above the seasonal averages.
