The episode as NWS OAX wrote it up.
An area of light snow fell across southeast Nebraska early in the morning on February 4th. Amounts were generally an inch or less. The highest amount was 1.5 inches at Feirbury in Jefferson County. Some wind with the light snow caused blowing snow conditions.

Area Forecast Discussion National Weather Service Omaha/Valley NE 331 AM CST Sun Feb 4 2018 .SHORT TERM...(Today through Monday Night) Issued at 322 AM CST Sun Feb 4 2018 At 3am wind chills ranged from 10 degrees in far southeast Nebraska to around -18 in far northeast Nebraska with winds gusting from 20 to around 35 mph. A quick burst of light snow continued to make its way out of southeast Nebraska and southwest Iowa. Wind chill values may flirt with -20 near the NE/SD border this morning for an hour or so, but are not expected to warrant a wind chill advisory at this time. Another round of light snow will graze the southeastern portion of the CWA this morning, dropping accumulations of an inch or less mainly along and southwest of a line from Albion to Falls City. Skies will clear behind this system this afternoon, but temperatures will struggle to reach the mid teens. Chilly conditions will continue through Sunday night with lows in the single digits. Another more robust looking wave will make its way out of the northern Rockies, and impact the area early Monday morning through Monday evening. This system appears to have relatively strong isentropic upglide and Q-vector convergence at both the upper and lower levels Monday morning. The NAM and GFS produce 3-4 inches across the northeastern half of the CWA and a quick analysis with the Garcia method indicates amounts of up to 6 inches may be possible in western Iowa. On the other end of the spectrum, the ECMWF and SREF remain more conservative and progress the wave further west, leaving us with an inch or less. Bottom line, the energy driving this system currently resides over the Gulf of Alaska, making it hard to pin down specifics just yet. For now the best estimate is likely 1-4 inches along and northwest of a line from Niobrara, NE to Clarinda Iowa, with highest amounts in west central Iowa. .LONG TERM...(Tuesday through Saturday) Issued at 322 AM CST Sun Feb 4 2018 Then next round of snow in this active pattern looks to impact the region Tuesday through Tuesday night. The NAM appears to be trending towards the more optimistic ECMWF, bringing precip through the majority of the CWA. The GFS continues to counter this with the wave merely skimming along the KS/NE border. However, most models seem to agree that temperatures will remain cool Tuesday with highs in the teens and 20s. Wednesday and Thursday will be dry and slightly warmer before colder air and another shot at light snow arrives Friday. Once again models diverge on the timing and strength of this frontal passage. && .AVIATION...(For the 06Z TAFS through 06Z Sunday night) Issued at 1127 PM CST Sat Feb 3 2018 Upper level disturbance dropping out of the Dakotas has helped induce areas of -SN currently dropping into nern NE. Given activity is widely scattered in nature, will limit TEMPO groups to 2 hours at all terminals. MVFR cigs then expected to prevail until mid morning, with conditions improving to VFR by late morning. Tight pressure gradient over the region will keep NW winds rather gusty through most of today. Crosswind threat is minimal at best. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && SHORT TERM...KG LONG TERM...KG AVIATION...DEE
