What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Las Vegas, NV wrote its last area forecast discussion before this winter storm warning went out at Jan 7, 12:52 AM PST, 16 minutes earlier.
Area forecast discussion, Jan 7, 12:52 AM PST, 16 minutes before
Area Forecast Discussion National Weather Service Las Vegas NV 1252 AM PST Sat Jan 7 2023 .SYNOPSIS...Dry conditions expected this weekend, with the exception of light valley rain and high elevation snowfall for western Inyo County. The active pattern continues, bringing another round of widespread precipitation to the region Monday and Tuesday. && .SHORT TERM...Today through Sunday night. Considerable area of clouds is on the increase across California as next in the series of systems set to primarily impact California this weekend. HREF % of cloud cover guidance shows this swath of considerable cloudiness continuing across our area through midday Sunday before we could see some partial clearing. High temperatures will be slightly impacted by the cloudiness with reading one or two degrees off of yesterdays highs. Any significant wind gusts of 30-40 mph over the weekend will be isolated to the higher elevations of Inyo County and southern Nevada. Regarding precipitation, radar currently shows leading edge of precipitation moving onshore from the SF Bay area northward. Minor AR associated with incoming shortwave trough Sunday will is forecast to drive the AR down the coast to Pt. Conception. But, all deterministic guidance indicates this AR will fizzle out before causing much impact to the southern Sierra of Inyo County. Both ensemble and deterministic guidance indicate light precipitation for the Owens Lake and Crowley Lake basin. Based on latest snow level and snow ratios this should translate to 3-6 inches of snow above 8500 feet. .LONG TERM...Monday through next Friday. Upgraded our Winter Storm Watch to a Winter Storm Warning above 6000 feet for Monday-Tuesday evening for the Sierra and White Mountains of Inyo County. This is the time frame for the next significant AR event, a 48 hour period from early Monday through Tuesday evening. When the heavier precipitation begins early Monday morning, the snow level in the Sierra is forecast to be 4500-5000 feet then rise through the day to around 8000 feet then lowering again to 6500-7000 feet Tuesday morning and finally to 5000-5500 feet by the end of the event. This fluctuating snow level will make for a difficult snowfall forecast. As it sits now, elevations 6000-8000 feet could get 8-14 inches, Aspendell could get 1-2 feet while the highest elevations could get 2-5 feet. There is still a lot of uncertainty with a 18 inch spread between the NBM 10th and 90th percentile for Aspendell. Elsewhere, current snowfall forecasts of 8-14 inches at Westgard Pass in the White Mountains with higher amounts at the peaks, 6-10 inches over Highway 266 in Esmeralda County and 4-8 inches in the Spring Mtns. Still plenty of time to lock in amounts before the Winter Storm Watch would need to be upgraded to a warning. Impressive rain amounts are forecast in Inyo County with 0.75-1 inch amounts in Death Valley and 1.50-2.50 inches in the Owens Valley. Once this system moves out Tuesday night, a dry period is forecast from Wednesday through Thursday night before another weaker AR wave brings heavy snow to the Sierra for Friday and Friday night. Long range forecasts for the weekend (beyond the official 7-day forecast) show another possible significant AR event potentially bringing feet of snowfall to the Sierra and White Mountains. && .AVIATION...For Harry Reid...Light winds of 8 kts or less favoring typical diurnal variations are expected through the TAF period. High clouds will develop this morning and persist into Sunday, and mid- level cloudiness will form this afternoon. Overnight, increasing moisture from a Pacific storm will spread across the area. While no significant impacts are expected at the field, lower cloud bases could result in some of the ridges to the west of the Las Vegas valley being obscured Sunday morning. For the rest of southern Nevada, northwest Arizona and southeast California...Light winds favoring typical diurnal variations are expected at most regional TAF sites today and tonight, except KIFP, where breezy northerly winds are likely this afternoon. Increasing moisture from a Pacific storm will spread across the region later today through Sunday. While only an increase in high and mid-level clouds is expected at regional TAF sites, mountain snow and reduced visibilities are expected across the Sierra and White mountains later this afternoon and overnight. Likewise, on Sunday morning, reduced visibility and mountain obscuration are also possible across the Spring Mountains. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM...Pierce LONG TERM...Salmen AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
