Two days of heavy rain led to isolated flash flooding in Nemaha County.
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 Jun 4, 2:08 AM CST, 2 hours 41 minutes earlier.
Area Forecast Discussion National Weather Service Omaha/Valley NE 308 AM CDT Tue Jun 4 2019 .SHORT TERM...(Today through Thursday) Issued at 300 AM CDT Tue Jun 4 2019 At 3 AM, skies were mostly cloudy with a multicellular cluster of thunderstorms moving through southeast Nebraska. The storms were producing some brief heavy rain and small hail. However they were less intense compared to earlier in the evening, and the overall severe threat appeared to be low. Surface winds over the region were light out of the southeast and temperatures ranged from the mid 60s to low 70s. Kind of a messy setup today with a shortwave and associated surface low over the north Central U.S. A warm front extending south from the surface low, through eastern portions of the Dakotas/Nebraska this morning, will push east through the day. This should usher in a warmer airmass (afternoon highs in 86-91 degree range) and be the focus for convection over parts of Iowa this afternoon/evening. Meanwhile, a surface pressure trough looks like it will set up across central and northeast Nebraska by late afternoon, and it could interact with a weak shortwave propagating out of the Black Hills later to produce a few thunderstorms. Any lingering boundaries from this mornings convection could also be a factor later today. Overall parameters for thunderstorms are modest, with decent instability (2,000-3,500 j/kg of MUCAPE) and limited 0-6 km shear (15-30 kt). This favors mainly multicellular storms, with an isolated wind and hail threat. Overall forecaster confidence in storm location later today is low, with moderate confidence in at least isolated storm coverage this afternoon/evening. A couple strong to severe storms can't be ruled out. A few thunderstorms could linger over the area tonight, though the loss of diurnal heating will limit instability. Outside of this the weather should be uneventful, with light winds and overnight lows in the mid 60s. Winds turn northerly Wednesday as a weak cold front pushes southward and surface high pressure settles in. Despite the frontal passage, we should see mostly dry and warm weather Wednesday. Look for afternoon highs in the mid 80s. The one exception may be along the KS/NE border, where an isolated evening thunderstorm is possible as the front stalls. The forecast for Thursday hinges on the location of the aforementioned surface front, and how far northward it drifts as the surface high moves east. At this time model consensus places it over southeastern Nebraska, suggesting some potential for isolated thunderstorm activity throughout the day. .LONG TERM...(Friday through Monday) Issued at 300 AM CDT Tue Jun 4 2019 The weather pattern for the upcoming weekend will be defined by a unseasonably strong trough in the Pacific Northwest and a closed low edging into the western periphery of longwave ridge over the Eastern U.S. Nebraska and Iowa look to be caught in between the two, with the potential for thunderstorms this weekend dictated by the track of the closed low. As uncertainty is still moderate, decided to stick with a slight chance of thunderstorms each day (Friday-Sunday). Temperatures should be the definition of average this weekend with afternoon highs in the upper 70s or low 80s. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1125 PM CDT Mon Jun 3 2019 Isolated TSRA have developed east of KOFK and north of KOMA as of around 1125 pm. These should track northeast. Area of storm in southwest NE will continue to move east and may expand a bit on the northern flank. These should move through eastern NE and western IA later tonight into Tuesday after sunrise. Some MVFR conditions possible in the TSRA. Some model guidance continues to suggest MVFR ceilings later tonight into Tuesday morning, even outside of TSRA. Confidence on this is getting higher. && .OAX WATCHES/WARNINGS/ADVISORIES...
