The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tulsa, OK wrote its last area forecast discussion before this special weather statement went out at Jun 1, 3:28 PM CDT, 1 hour 18 minutes earlier.
Area forecast discussion, Jun 1, 3:28 PM CDT, 1 hour 18 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 328 PM CDT Thu Jun 1 2017 .DISCUSSION... Weak trough axis noted across southern Oklahoma has resulted in scattered showers and thunderstorms across southeast Oklahoma...with less coverage observed across northwest Arkansas. Short term local guidance indicates most activity will remain diurnal in nature...so will follow accordingly by keeping low pops in for the first period. Larger scale upper trough in conjunction with an uncapped environment will keep the area unsettled through the weekend. The aforementioned upper feature will be slow to advance east...but expect an uptick in areal coverage by the first half of the weekend as it moves into the southern plains. By Sunday...as the trough axis settles further south and east a weak boundary will move into at least parts of the area. Rain/thunder chances to remain highest across southeast Oklahoma...with lower pops further north and west. Early next week...an upper system across the northeast CONUS and weak ridging to the west will keep the forecast area on the cusp of weak meridional N-S flow. Not really a favorable pattern for MCS development. That...and drier air advecting into the area from the north-northeast...will opt to keep the last few periods of the forecast cycle dry for now. As for temperatures...ample cloud cover and forecasted rain chances will keep temperatures down...thus the cooler guidance temperatures have generally been followed. && .PRELIMINARY POINT TEMPS/POPS...
