The episode as NWS LKN wrote it up.
An atmospheric river brought periods of rain and winds ahead of more substantial mountain snows.
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 Elko, NV wrote its last area forecast discussion before the first event at Dec 27, 2:11 AM PST, 5 hours 19 minutes earlier.
Area Forecast Discussion National Weather Service Elko NV 211 AM PST Tue Dec 27 2022 .SYNOPSIS...Mostly cloudy today with above normal temperatures. Expect windy conditions throughout Tuesday with a wind advisory beginning at 4 AM and ending at 10 PM PST Tuesday evening for Humboldt and Northern Elko counties. Periods of rain are expected throughout the day changing to snow Tuesday night into early Wednesday morning. This period of weather is the first of an active period reaching into Sunday morning. && .SHORT TERM...Today through Wednesday Night. A period of active weather has begun. An atmospheric river has been transporting moisture into the region producing periods of rain throughout the CWA, above normal temperatures and gusty winds heading into Tuesday evening. The most likely amount of liquid equivalent for NW NV and SW central NV will be 0.15" to 0.25" with a few areas seeing a little higher and a little lower depending on localized areas of precipitation shadowing. Expect higher amounts of precipitation in west central NV with around 0.33" to 0.66". Elko and White Pine are expected to receive 0.5" to 1" in the valleys and 1" to 2.5" for the mountains with higher amounts favoring higher elevations. Precip type will be of the liquid variety into Tuesday night where falling temperatures and lower snow level elevations will change the precip to snow. Warm southerly winds will keep temperatures above normal for Tuesday with most areas being in the 40s to 50s. Without the warm southerly winds Wednesday we will see cooler conditions with highs falling into the 30s and 40s. While the snowfall will be limited it can still cause icy roads and adverse travel conditions. Likewise the winds will make for adverse travel conditions especially so for high profile vehicles. .LONG TERM...Thursday through Next Tuesday. Active weather remains through the New Year and beyond. By early Thursday morning the next of several systems to greet the state will be producing snow showers across the area. Snow will be light, but will persist through the day and night. Valleys may see anywhere from a trace to 2 inches, with mountains likely seeing in the neighborhood of 3-5 inches. Thursday night, and Friday, snow levels rise above 7000 feet south of I-80, and around 6300 feet near and north of I-80. This will contribute to snow changing over to a rain/snow mix, and all rain in some areas, from west to east. In general valleys can expect to see another trace to 2 inches Friday, with mountains seeing in the order of 1-2+ feet. Snow levels begin to fall through Saturday. A rain/snow mix may still remain for areas of Humboldt, Lander, and portions of Eureka, and Nye counties. Current thinking are for snow levels to remain low enough for mostly snow across Elko and White Pine counties. With that thinking expected snowfall in valleys will remain trace to 2 inches, with valleys across Elko and White Pine seeing 2-5 inches, and mountains adding another 1-2+ feet. Sunday, slightly cooler air moves in as the existing system begins to take a dive south and east of the state. Light snow showers will occur, with another 0-1 inch in valleys, and 6-12 inches in mountains. Storm totals for mountains from Thursday through Sunday will generally range in the 1 to 3 foot range, with higher mountains such as the Ruby Mountain/East Humboldt range seeing 3 to 5 plus feet. With rainfall expected Tuesday night through Wednesday, followed by ample snowfall Thursday through Sunday, there is a heightened risk for avalanches to occur. A brief reprieve in active weather Sunday afternoon and overnight is short lived as the next system on deck looks to take a swing at Nevada to start the next work week. Highs Thursday through Sunday will generally be in the 30s and 40s, with cooler high temperatures in the 20s and 30s working in by the start of next week. Lows generally in the teens and 20s with single digits also returning Monday. && .AVIATION...An approaching weather system will bring deteriorating flight conditions to much of the region today and tonight. Southerly winds increase today with LLWS becoming an issue mainly for KEKO between 17z and 22z. By late this afternoon and into this evening snow or a rain snow mix will likely further lower VIS at KELY and KEKO. && .LKN WATCHES/WARNINGS/ADVISORIES... Wind Advisory from 4 AM to 10 PM PST Tuesday for Humboldt County- Northern Elko County. Winter Storm Warning from 4 AM Tuesday to 10 AM PST Wednesday for Ruby Mountains and East Humboldt Range. Winter Weather Advisory from 4 PM Tuesday to 10 AM PST Wednesday for White Pine County. && 95/91/96
