Area Forecast Discussion National Weather Service Las Vegas NV 241 AM PST Fri Dec 6 2019
SYNOPSIS. Increasing clouds expected the next couple days with another round of mountain snowfall mainly in the Sierra and southern Great Basin. Periodic light rain showers are possible across the whole region over the weekend. Conditions dry out next week with high pressure building across the west coast.
SHORT TERM. through Sunday night.
Southwesterly flow aloft along with a fairly deep low off the NorCal coastline is resulting in a veil of high clouds which continues to dominate our skies along and south of I-15. Expect this cloud cover to shift east later today allowing for partial clearing for most of the region. GOES fog product does indicate there is some lingering fog across the valleys of eastern Inyo, Nye, and Esmeralda counties and so I added some patchy fog mention to the forecast through this morning hours.
Offshore trough will begin to edge closer late tonight into Saturday, with increasing warm advection/upslope snowfall breaking out across the Sierra. Suspect this initial precipitation will be fairly light, with limited spillover but perhaps a few inches falling around Aspendell by Saturday morning. Heavier Sierra precipitation will move in Saturday evening into Sunday morning, when the brunt of heavier snowfall will occur above 7000 feet. Went ahead and converted the Winter Storm watch to an advisory, while also trimming snow amounts a bit as the greatest moisture transport will be directed more into Northern and Central California than the south Sierra. Nonetheless, a storm total of 8-12 inches is a good bet above the 8000 foot level over the weekend.
Elsewhere, a couple of enhanced periods of precipitation will exist over the weekend. The first will occur Saturday as a narrow band of moisture seeps into the Mojave Desert from SoCal. Amounts will be light, but a few showers may break out as this band traverses from west to east during the afternoon and evening. Higher terrain such as the Spring Mountains may wring out better totals, and an inch or two of snow. On Sunday, the trough axis will sag overhead resulting in steepening lapse rates and sparking scattered shower activity, especially across southern Nevada and Northwest Arizona.
LONG TERM. Monday through Thursday.
High pressure will build across the region next week with a dirty ridge pattern setting up across the west. This will allow for warming temperatures, tempered by the development on surface inversions, along with periods of high clouds.
AVIATION. For McCarran . Light and variable winds expected to continue through today and early tomorrow morning, favoring typical diurnal directions. VFR conditions with BKN-OVC aoa 20 kft before becoming mostly FEW aoa 20 kft by this afternoon. Another weather system is expected this weekend which will bring some gusty winds, shower chances and another round of low ceilings.
For the rest of southern Nevada, northwest Arizona and southeast California . Mostly light and variable winds expected across the region today. Continued low clouds in the Owens Valley will keep cigs between 2-5 kft through Friday morning. Low ceilings may lift later this afternoon, but confidence is low and will depend on how strong the afternoon winds get. Some breezy southeast winds are possible at KBIH later this afternoon, but there is low confidence that these winds actually materialize, if so, they should generally remain below 10-15 knots. Elsewhere, expect ceilings aoa 20 kft.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
