The episode as NWS GID wrote it up.
Mainly between 8 a.m. and 3 p.m. on this Saturday, a sneaky mesoscale snow band flared up across limited portions of South Central Nebraska, dumping as much as 2-5 inches of slushy/wet snow along a southwest-northeast oriented swath only 10-20 miles wide (if even that)...roughly centered along a line from Republican City-Campbell-Juniata-Doniphan. Although snowfall amounts in the heart of this band solidly exceeded forecast expectations of 1 or less, impacts were held in check, due in part to light winds only around 10 MPH. Per a limited number of mainly NeRAIN and social media reports, along with NOHRSC analysis, some of the highest reported snow totals featured: 5.0 in Republican City and six miles north of Campbell, 4.5 at Harlan County Lake dam, 4.0 in Naponee and Bloomington, and between 3.0 and 3.2 within western through north central Adams County (including the Roseland and Juniata areas). Just outside the heart of the main band, lesser totals of no more than 1-2 prevailed in places such as Hastings and Orleans, while amounts under 1 were noted farther northeast along this precipitation axis in locations including Grand Island, Central City and Osceola. Even where the heaviest amounts fell, snow cover did not last very long, with some of it melting already on the afternoon of the 2nd after precipitation ended (temperatures rose to at least 35 degrees F), and the remainder of it disappearing on the 3rd (high temps mainly 40s F).
Taking a closer look at the meteorological background and event timing, and starting in the mid-upper levels, the main player was a broad shortwave trough that traversed the heart of the Central Plains from west-to-east during the calendar day of the 2nd. Looking into the lower levels, this mesoscale snow band was clearly tied to the development of a narrow stripe of frontogenesis particularly evident between 700-850 millibars. At and near the surface, the temperature profile was just cold enough to support wet snowfall, with temperatures hovering mainly between 29-32 F as it fell. The initial onset of narrow snow banding got underway mainly between 8-10 a.m. within Furnas, Harlan and Franklin counties. Over the next few hours, this snow swath expanded northeastward into especially southeastern Kearney and western/northern Adams counties. During the early-mid afternoon hours, snow migrated northeastward into parts of especially Hall, Hamilton, Merrick and Polk counties, but with accumulation more muted thanks to at-or-slightly above freezing temperatures melting much of it as it fell. The final flakes of the day gradually departed far northeastern local counties (such as Polk/Merrick/York) between 4-6 p.m.

NWS Hastings, NE wrote its last area forecast discussion before the first event at Dec 2, 4:29 AM CST, 31 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Hastings NE 429 AM CST Sat Dec 2 2023 .DISCUSSION...(Today through Friday) Issued at 415 AM CST Sat Dec 2 2023 Key Messages: * Forecast remains on track for a minor band of snow to bring the potential (30-50% chance) for up to around a half inch of accumulation today, mainly in the 6AM to 4PM time frame. This could lead to a couple hours of slick roads, mainly this morning * Low end chances (20-30%) for rain/snow mix have been added to the forecast for Sunday with another brief disturbance, mainly for areas N and E of the Tri-Cities. However, the more widespread weather aspect will be gusty NW winds of 30-40 MPH. * Main story for the new work week will be steadily rising temperatures...becoming unseasonably warm by Wed and Thu with highs in the upper 50s to upper 60s! Forecast Details: Quick look at the "big picture" early this morning reveals a broad upper trough with main axis running N/S along Rockies/High Plains region. Subtropical ridging is noted over the Caribbean, nosing into the Gulf of Mexico, with seasonably fast SWrly upper flow noted between the trough/ridge. Several shortwaves/vorticity maxima can be seen within the broader trough, with our next weather maker for today ejecting NE from CO into NW KS. This wave will try to deepen/phase with another small piece of energy near Salt Lake City and produce a small/narrow swath of minor snow today (see next paragraph for more details). Yet another shortwave can be seen moving onshore the Pac NW that will quickly slide SE and affect the region on Sunday. Overall, this pattern is not too dissimilar to 24 hrs ago when today's wave was also just moving onshore the Pac NW. This pattern is not uncommon with strong and persistent "atmospheric river" events where several vorticity maxima/shortwaves are embedded within a strong upper jet - which can be difficult for the models to get a handle on more than 24 hrs in advance due to small/compact nature, quick movement, and lower density obs over Pacific Ocean. This explains the addition of precipitation chances for Sunday (see third paragraph), which was alluded to as a possibility in yesterday AMs AFD. As for today's minor snow band...again not a lot of changes to the forecast with this package. Radar returns have been steadily incr over NW KS over the past hr and expect this trend to continue as the wave shifts NE through the day today. Will take some time to saturate the lower levels given sfc dew points only in the teens, but once that occurs, forecast soundings suggest the potential for a couple hours of a "burst" in intensity within a relatively narrow SW to NE corridor. Areas with greatest risk (30-50% chance) for minor snow accums of dusting to half inch look to be 30 miles on either side of a line from around Alma to Central City. The timing, along with potential brief bursts of moderate snow, could lead to some slick roadways mainly this morning when temps are coldest. Temps are forecast to rise into at least mid 30s to around 40 areawide (perhaps mid 40s far W), which should limit impacts for the aftn hrs. Wind will be modest today out of the S at only 5-15 MPH. Certainly not a situation where folks should cancel plans today, but wouldn't hurt to allow for extra time this morning, particularly for areas around Tri-Cities and to the SW. Yet another disturbance will slide through the area on Sunday, though this time with more of a NW to SE track as the broader upper trough axis slides into the MS River Valley. This wave has a very compact, but potent, look to it on satellite this AM, and models have generally trended stronger with it over past 24 hrs. As such, have introduced some low end 20-30% precipitation chcs for areas mainly N and E of the Tri-Cities to account for this. Looks like precipitation type could be a mix of rain and snow, depending on precipitation intensity and exact timing. With more of a midday or aftn timing and temps generally at least a couple deg warmer than today, favor the idea of more rain than snow, and thus currently do not have any snow accumulations for Sunday with this forecast and currently not expecting any travel impacts. Precip chcs with this wave favor NE portions of the forecast area, but a much broader sensible weather aspect will be strong NWrly wind gusts of 30 to 40 MPH, perhaps locally up to around 45 MPH. So even though temps may be a bit warmer than today, its not going to be anymore pleasant bc of the wind. What WILL BE more pleasant is the weather for the upcoming work week, particularly in the Wed-Thu time frame. Models remain consistent that temps will steadily warm over the next several days, likely peaking Wed into Thu with highs across the board in the upper 50s to upper 60s...which is easily 15 to 20 deg above normal for early Dec. There will be some breeze to accompany the warmup, particularly on Thu, but really not that bad by Dec standards as gusts are forecast to peak mostly below 30 MPH. While not a glaring concern at this time, wouldn't be surprised to see at least some elevated fire weather concerns with the warmup, as well, at least for far SW/W counties (like Furnas to Rooks). Ensembles are in general agreement that temps will decr late next week into next weekend, though there remains significant differences w/r/t the rate/magnitude of cooling. Broadly speaking, there are hints of a potentially more active wintry weather period towards the 10th, or so, of the month, which could may garner some social media attention given dearth of active weather between now and then. Take any specific info you may see regarding that time frame with a giant grain of salt, though, as any potential system is likely at least a week (7+ days) away and much can (and will) change in the modeling over that time. && .AVIATION...(For the 06Z KGRI/KEAR TAFS through 06Z Sunday) Issued at 1058 PM CST Fri Dec 1 2023 A band of light snow is expected to move into the area Saturday morning. Ceilings remain a little uncertain, but at least a short period of MVFR conditions are possible. Snow accumulation will be very minor, and any visibility restriction will be brief. This activity clears out late afternoon and winds shift to he west Saturday night. && .GID WATCHES/WARNINGS/ADVISORIES... NE...NONE. KS...NONE. && DISCUSSION...Thies AVIATION...Mangels
