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 Reno, NV wrote its last area forecast discussion before the first event at Mar 28, 12:55 AM PST, 5 hours 5 minutes earlier.
Area Forecast Discussion National Weather Service Reno NV 155 AM PDT Mon Mar 28 2022 .SYNOPSIS... Today will feature periods of mountain snow, rain showers in the lower elevations, notably cooler temperatures, and a few thunderstorms this afternoon and evening. Travel over Sierra passes may be affected at times especially this morning. The remainder of the week looks dry with temperatures a few degrees above average, and periods of afternoon breezes. && .DISCUSSION... The leading edge of the primary precip band in central CA is on track to reach the Sierra early this morning between 4-7 AM, with a push into the Tahoe basin and parts of far western NV after 7 AM--a bit later onset compared to previous guidance. For the remainder of the day, bands of rain and snow showers will continue developing especially south of US-50, with a few thunderstorm cells added to the mix by mid-late afternoon and sustained into this evening, aided by a weak upper disturbance over northern NV. Later this evening and overnight, the general idea presented by the high resolution guidance is for wrap-around shower bands over northern NV to push back southward across the I-80 and US-50 corridors, with lingering showers from west central NV southward to Mineral and Mono counties through Tuesday morning. Lower elevation rain details... The showery nature will produce hit or miss amounts, reflected by the varied probabilities of 0.10" rainfall ranging from 20-60% for much of western NV and northeast CA, while chances for at least 0.25" range from 5-25% in the latest blended guidance. The higher end of this range generally favors areas south of US-50, while the lower end is indicated for northwest NV, associated with the upper low center appearing to track a bit farther south across southeast CA-northern AZ. Even so, the final location of the heavier showers/t-storms and subsequent wrap-around bands this afternoon through tonight could produce a few "winning" precip totals farther north and "losing" totals farther south. Sierra precip/snow details... The bulk of the Sierra snow and travel impacts is likely to occur this morning as the primary band moves in. Then as the transition to convective shower bands takes place this afternoon and evening, additional snowfall will become more spotty. Snow levels initially at high elevation near 8000 feet will quickly settle near 6000 feet as wet bulb cooling sets in early this morning, and remain at similar levels through much of the event, except edging upward to around 6500 feet during the afternoon. The projected accumulations in the advisory area still look on target with the higher end of the 5-10" range favored for Alpine-Mono counties, while areas north of about Carson Pass appear headed for the lower end of this range. Below 7000 feet, a shorter duration of nighttime snow with the slight delay in onset time early this morning will limit snow accumulations to less than 4" on unpaved surfaces. Most roads below 7000 feet will likely be wet through today, except short periods of slush through mid-morning during heavier snow rates. Thunderstorm details... A few embedded lightning strikes are possible around midday or early afternoon near the Sierra with the primary precip band, then later this afternoon the potential for isolated lightning expands to include much of western NV and northeast CA with shallow convection in a cool but slightly unstable air mass. The stronger cells may also produce brief periods of accumulating pellet/small hail showers and localized wind gusts to 40 mph. If you are planning outdoor activities this afternoon, be prepared to seek shelter if a thunderstorm develops near your location. Tuesday through early next week... Temperatures on Tuesday will have a slight rebound to the lower- mid 60s for lower elevations and lower-mid 50s near the Sierra, although it will seem cooler with moderate northwest breezes (gusts 20-25 mph) and lingering clouds into the afternoon. Temperatures will generally be about 5-10 degrees above average into next weekend with the pattern appearing to favor a flatter west to northwest flow. A weak shortwave passage brushing by to the north Wednesday-Thursday brings a bit of cooling and northwest to north breezes, then another trough later in the weekend into next Monday may bring a few showers and a similar slight drop in temperatures. Precip looks more sparse with this system compared to previous ensemble guidance, and no other meaningful chances for rain or snow are indicated through the first week of April. MJD && .AVIATION... Southerly winds will continue through approximately 18z with FL100 winds sustained around 40-60 kts and valley gusts of 20-30 kts, locally up to 40 kts south of US-50. Expect turbulence across the Sierra along with bouts of wind shear. WNW winds to follow into this afternoon, peak gusts 15-25 kts. Rain and snow evident on radar in the Sacramento Valley as of the time of writing will continue eastward, reaching the Sierra between 11-13z, and spreading into western Nevada between 14-16z. Light slushy accumulations up to 1" of snow are possible through 18z Monday at Sierra terminals, and while rain/snow showers are likely through the day, runway accumulation will be hard to come by given the high sun angle this time of the year. Western Nevada terminals will only see rain showers. There are also chances for thunderstorms (10-20% at any given location) from 18z-03z today. Storms may produce a brief heavy downpour, hail and/or graupel, and lightning. Precipitation will be banded and showery in nature, meaning there may be rapid changes to CIGS/VIS over short distances and terrain obscuration should be anticipated across the region. High resolution CAMs are indicating an organized band of showers developing tonight near/north of I-80 moving from north to south, which may bring another period of precipitation to KRNO/KCXP/KMEV/KNFL/KTRK/KTVL overnight. All signs point toward this band weakening and/or dissipating between 13-16z Tuesday. -Dawn && .REV Watches/Warnings/Advisories... NV...Winter Weather Advisory until 8 PM PDT Monday NVZ002.

Be prepared for delays and wet or snow covered mountain passes if you need to travel over the Sierra today. Showers will linger tonight, diminishing into Tuesday morning. * Liquid totals (0.50 to 1 inch) will be highest along the Sierra crest from Tahoe south through Mono County, with light amounts for communities (0.25 inch or less) in the eastern Sierra and western Nevada south of Interstate 80. Locally higher totals are possible due to the showery nature of the precipitation. There is a 10-20% chance of thunderstorms today which may impact outdoor recreation. * Snow levels will remain near and above 6000 feet, with snow accumulations mainly limited to passes above 7000 feet due to the recent warmth and late-March sun angle. The only exception will be early this morning, where light, slushy accumulations may occur as low as 6000 feet. The high Sierra could pick up 5 to 10 inches of snow, with locally higher amounts in Alpine and Mono Counties. * While nothing out of the ordinary, it will be significantly cooler today compared to the recent warmth and highs may struggle to reach 60 degrees in the warmest of valleys. * Breezy southerly winds this morning may bring travel difficulties for high profile vehicles and choppy conditions to area lakes. Winds to turn northwesterly and become lighter this afternoon. http://weather.gov/reno
