Storms in eastern Oklahoma propogated westward into central Oklahoma on the afternoon of the 28th, producing an isolated severe wind gust.
The local office's own words before the first event, 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 the first event at Jul 28, 2:01 PM CST, 2 hours 44 minutes earlier.
Area Forecast Discussion National Weather Service Norman OK 301 PM CDT Sat Jul 28 2018 .DISCUSSION... The primary forecast issue is the chance of showers/storms through Monday. Showers/storms are developing across eastern Oklahoma in association with a remnant MCV. Scattered showers/storms will be possible through this evening, primarily across southeast Oklahoma. Upslope flow across eastern Colorado has resulted in showers/storms developing across the foothills. These thunderstorms are expected to coalesce into complex of thunderstorms that will move southeastward across western Kansas. This complex of thunderstorms is forecast to move northern Oklahoma around midnight. A moderate low-level jet--30 to 35 knots--near the Kansas/Oklahoma border along with effective bulk shear >50 knots and MUCAPE >1500 J/kg should result in a continued threat for strong to severe thunderstorms near the border; however, the low- level jet does weaken with southeastward extent. Therefore, the expectation is a gradual weakening trend once the storms enter the state. For Sunday afternoon, there is some uncertainty on the forecast as tonight's MCS will result in remnant boundary somewhere in Oklahoma--perhaps near or south of I-40. Redevelopment of showers/storms may occur along or south of this boundary Sunday afternoon. Very hot temperatures (low to mid 100Fs) may occur across southwest Oklahoma/western north Texas, ahead of this remnant boundary as well. Another MCS is forecast to approach from the northwest Sunday night into Monday. In addition, a shortwave trough is forecast to amplify across the Plains/Midwest Sunday into Monday. The amplification of the trough will also result in a cold front with much cooler temperatures to pass by on Monday with a continued low to moderate chance of showers/storms. High temperatures for the northern two-thirds of Oklahoma are forecast to only be in the low to 80Fs--around 10 to 15 F below average. With an amplified ridge across the western U.S. and an amplified trough across the eastern U.S., the Plains will remain in persistent northwesterly to northerly flow aloft through Wednesday. This should result in cooler than average temperatures and low dew points/relative humidity. There is a chance a complex of showers/storms may affect far western Oklahoma/north Texas late Wednesday as a shortwave trough passes by in the northerly flow aloft. Temperatures may moderate closer to average by the end of the week as the eastern U.S. trough deamplifies and the western ridge expands eastward. Hotter, above-average temperatures, may return just beyond the forecast period. Mahale && .PRELIMINARY POINT TEMPS/POPS...
