In the early morning hours of Sep 1 a line of thunderstorms moved through southeast Nebraska into far northeast Kansas. The line began to bow out along the state line, and this where strong winds made it to the surface.

The episode as NWS TOP wrote it up.
In the early morning hours of Sep 1 a line of thunderstorms moved through southeast Nebraska into far northeast Kansas. The line began to bow out along the state line, and this where strong winds made it to the surface. A few large trees, some small branches, and power poles were brought down due to the winds.
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 Topeka, KS wrote its last area forecast discussion before the first event at Sep 1, 2:04 AM CST, 1 hour 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TOPEKA KS 304 AM CDT Sun Sep 1 2013 .SHORT TERM...(Today and Tonight) Issued at 302 AM CDT SUN SEP 1 2013 Upper trof moving across the northern plains is ushering a cold front southward into the central plains. Cluster of storms extends from Iowa back into eastern Nebraska, where it becomes a bit more broken and then extends back into north central Kansas. Another convective complex has rolled off the Colorado Rockies and into southwestern Kansas as well, with a leading cold pool moving eastward toward Russell. Storms forming generally along the front, and starting to see some cold pool development pushing just east and south of the storms approaching our area from the north. Most convection expected to move from NW to SE across the forecast area and be along or south of the I35 corridor by early afternoon. Until then, with CAPE values running up to 2500 J/kg and bulk shear around 20 to 25kts, could see an isolated severe chance with wind the primary threat. Lapse rates are steep, but more so below the freezing level, and soundings not as dry as in previous days. May get some locally heavy rainfall with PW values around 1.5 inches. Anticipate boundary to move south quickly, but still an outside chance that southern counties may get enough heating for an isolated afternoon storm as the front comes through. Highs are very tricky, ans temperatures behind the rain are in the 70s, in line with current temperatures. Skies appear to clear quite quickly however, and will go with highs in the 80s north with lower 90s south where expanding high clouds should help keep a lid on high temperatures until the front passes. Quickly clearing skies and low dewpoints should allow temperatures to fall into the upper 50s north and low 60s elsewhere. Will need to watch for fog potential depending on rainfall today. .LONG TERM...(Monday through Saturday) Issued at 302 AM CDT SUN SEP 1 2013 Monday night high pressure at the surface will extend into eastern KS, which should support decent radiational cooling. Allowing low temperatures to drop into the mid to upper 50s with the exception of north central KS which will stay in the low 60s. The upper high will stay centered over the central Rockies through mid week placing the area under northwest flow. On Wednesday the models are in good agreement that a weak shortwave will move along the northern extent of the upper ridge then southeast across the region. A surface trough develops over the high plains which then moves eastward into the area Wednesday night. Therefore there is a slight chance of showers and thunderstorms Wednesday night as the system passes through. By late week a strong upper low progresses eastward across the northern Rockies shoving the upper high southwest and flattening the ridge over the central plains. High temperatures will moderate into the upper 80s to low 90s and possibly the mid 90s by next weekend. Low temperatures will also moderate through out the week generally in the mid to upper 60s although back into the 70s by next weekend. && .AVIATION...(For the 06Z TAFs through 06Z Sunday Night) Issued at 1150 PM CDT SAT AUG 31 2013 Expect VFR conditions with light winds through 13Z. There is some potential for TS, mainly between 10Z and 13Z, but for now have not included in the TAF as there is much uncertainty regarding overall coverage of any TS. Winds turn out of the north and increase to around 10 kts by afternoon. && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...67 LONG TERM...Sanders AVIATION...Barjenbruch
