The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Jul 14, 2:29 PM CDT, 4 hours 44 minutes before
Area Forecast Discussion National Weather Service Little Rock AR 229 PM CDT THU JUL 14 2016 .SHORT TERM...Today Through Saturday Immediate forecast concern is the MCS approaching the forecast area from eastern Oklahoma. This convective system is expected to continue to slide to the southeast...along a well defined instability gradient...exiting the forecast area by 15/04z. Recent output of CAM type models have converged towards this solution. Near term forecasts account for the expected movement of this system. An additional complex is expected to form overnight to the west of the initial system...and again move to the southeast...affecting at least western sections after 15/06z. Mid level lapse rates...and forcing along smaller scale boundaries will provide support for convection during the rest of this period. Conditions supporting organized convective complexes...as of those supporting today's activity...are not expected. Any severe thunderstorm activity will be limited to diurnally enhanced...pulse type single cells. && .LONG TERM...Saturday Night Through Thursday If I could sum up the extended forecast in two words it would be "ridge" and "hot". An upper level ridge will dominate through the entire period and above normal temperatures will be the rule. Afternoon max values could top out over 100 in some areas. There will be some low precipitation chances toward the latter half of the period as the center of the ridge settles in over the mid plains. && .PRELIMINARY POINT TEMPS/POPS...
