A stronger two-part storm aided by an enhanced influx of subtropical moisture from a moderate atmospheric river continued the current series of Pacific winter storms passing through the region January 14-16. The initial thrust of AR enhanced moisture with the first storm brought heavy snowfall to the Sierra on 14 January with 2 to 3 feet of accumulating snow across higher elevations above 7000 feet.  An additional 15-30 inches of new snow fell across the California side of the Lake Tahoe Basin below 7000 feet with 8-16 inches falling on the Nevada side. Periods of heavy snow forced the closure of Sierra passes with the primary Sierra travel routes (I-80, US-50) being closed for much of the day. Precipitation started as rain for western Nevada on the 14th with rain totals of around a quarter inch and up to three-quarter inches for Reno-Carson City areas that continued south into the Carson Valley of Douglas County. Rainfall amounts with this storm surpassed the average water year precipitation of 7.35 inches on January 14th for the Reno area.  The second, colder wave of the same winter storm arrived overnight January 15-16.  This colder system produced 4-8 inches of total storm snowfall across the Reno-Carson metro areas including parts of Lyon-Mineral counties.  This system also dumped around a foot of snow across Douglas County. This second storm caused more significant travel impacts for western Nevada valleys/foothills.  Mono County and the Tahoe Basin also received an additional foot of accumulating snow accumulation with this colder follow-up to the winter storm system.
