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 Omaha, NE wrote its last area forecast discussion before the first event at Jul 12, 10:18 PM CST, 3 hours 37 minutes earlier.
Area Forecast Discussion National Weather Service Omaha/Valley NE 1118 PM CDT Fri Jul 12 2019 .SHORT TERM...(Tonight through Monday) Issued at 251 PM CDT Fri Jul 12 2019 Thunderstorms have developed in southeast SD and northwest IA this afternoon, likely north of a weak surface trough, and possibly related to remnant outflow for this morning's convection. These storms should not affect our area late this afternoon. More strong storms are expected to develop across the western High Plains late this afternoon and evening, eventually reaching northeast Nebraska very late in the evening and overnight, and probably not until 10-11 pm and beyond. By then, a storm or two could have gusty winds and some hail, but the better severe threat is to our west across central Nebraska. There is a small chance that some of the showers could hold together and make it as far south as I80 late tonight, and if they do, could linger for a couple of hours Saturday morning. Otherwise, Saturday will be another hot day with highs in the upper 80s to lower 90s, with afternoon heat index values in the mid 90s. Sunday through Monday remains dry, and slightly hotter, with daytime highs in the lower to mid 90s. Humidity starts to build by Monday, with afternoon heat index values 100 to 103, which will be the beginning of a prolonged period of excessive heat. .LONG TERM...(Monday night through Friday) Issued at 251 PM CDT Fri Jul 12 2019 ...Prolonged Period of Excessive Heat Possible Next Week... The excessive heat will be a big story next week, with conditions progressively getting worse each day. Highs in the lower to mid 90s to start the period, but warm into the 95 to 100 degree range by Wednesday and beyond. Nighttime lows in the lower to mid 70s, but mid to upper 70s in urban areas. With dewpoints in the upper 60s to mid 70s, this will create heat index values 100-103 on Tuesday, but 105-108 by Wednesday through Friday, which could persist into Saturday. These conditions would qualify for an excessive heat warning, due to the prolonged period of heat that is expected for 5 and possibly 6 days. This has also been a consistent trend over the previous couple of days, and we will likely need to issue an excessive heat watch later this weekend for most areas, followed by an excessive heat warning and some point. Bottom line, we're expecting conditions to become generally terrible for many consecutive days next week, especially Wednesday and beyond. Outside of the heat, we do have small nighttime thunderstorm chances in there Monday night though Wednesday night, north of I80. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1117 PM CDT Fri Jul 12 2019 A mature MCS over the NE Sandhills as of 11 PM is expected to undergo decay over the next few hours as the system cold pool outpaces the parent convection, and capping across the ambient warm sector strengthens. Nonetheless, it does appear that residual showers or a thunderstorm could move into the vicinity of KOFK by around 3 AM. Otherwise, VFR conditions are expected at all TAF locations through the forecast period with south winds of less than 10 kt. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.

Highs in the 90s are forecast each day, but warming to 95 to 100 by Wednesday and beyond. Heat index values should approach 100 this weekend, and will likely range 102 to 108 next week.
