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 Norman, OK wrote its last area forecast discussion before this special weather statement went out at Jun 18, 2:43 PM CDT, 7 hours 38 minutes earlier.
Area forecast discussion, Jun 18, 2:43 PM CDT, 7 hours 38 minutes before
Area Forecast Discussion National Weather Service Norman OK 243 PM CDT Tue Jun 18 2019 .DISCUSSION... Showers/storms will develop and move across the area through early Wednesday. There are several areas where initial storm development could occur this afternoon/early evening. One area is in southern Kansas down into portions of northern. Another is near the dryline in portions of the Texas panhandle and west Texas moving towards the fa. Any late afternoon/early evening storms could be discrete supercells with very large hail and strong wind gusts possible. There is also a low tornado risk with these storms. The storms are expected to merge into one or more storm complexes that move across the area later this evening into early Wednesday. These storms could also be severe with damaging wind threat becoming an increasing concern while the hail size and potential for tornadoes are expected to decrease. In addition to the potential for severe storms, heavy rain could lead to flooding in some locations late this evening into early Wednesday. Models show a boundary near the Red River area by Wednesday afternoon with storm development possible near the boundary, mainly in SE portions of the fa. Some of these storms could become strong to severe as well, although what happens Wednesday will be dependent on what occurs tonight into tomorrow morning. A brief dry period could be possible for much of the area Thursday into part of the day Friday. However, surface heating and any subtle disturbance in the flow that models can not resolve may lead to some storm development. The upper pattern will shift to SW flow Friday with a shortwave approaching and moving across the central/southern Plains over the weekend bringing another chance for showers/storms to the fa. && .PRELIMINARY POINT TEMPS/POPS...
