Area Forecast Discussion National Weather Service Las Vegas NV 810 PM PST Fri Dec 6 2019
SYNOPSIS. A Pacific weather system will bring increasing clouds another round of mountain snowfall to the Sierra tonight through Sunday. 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.
UPDATE. Evening radar is picking up on a few light showers/virga over the Colorado River Valley and western San Bernardino County. Overall, coverage has been on the decrease but still can't rule out a light sprinkle over southern Inyo, northern San Bernardino, and portions of Clark County. Measurable rainfall is not expected and these light showers will likely diminish after midnight. Just a few minor tweaks to the forecast to account for the light showers.
PREV DISCUSSION 320 PM PST Fri Dec 6 2019
DISCUSSION. Current satellite imagery shows a deep, closed low centered a few hundred miles west of of northern California. This Pacific weather system will bring a period of active weather to the region starting tonight. Most of the impacts with this system will be felt in the eastern Sierra where another decent round of snow is expected as a plume of modest moisture is directed into the Sierra. There wasn't much adjustment to the forecast snow amounts from the previous forecast, with 5-10 inches expected above 7,000 feet and a foot or more above 9,000 feet. That said, the Winter Weather Advisory looks good for the expected snow amounts. Southwesterly flow down stream of the trough axis will usher a second, more potent, plume of moisture into southern California tonight through Sunday. The poleward edge of this moisture will spread a swath of cloud and few showers into the western Mojave Desert area this evening before bringing mountain showers Saturday and Sunday. The warm, moist plume will raise snow levels closer to 9,000 feet for areas along and south of I-15, which will limit any significant new snow from accumulating in the Spring Mountains. The best chances for rain in the valleys (including Las Vegas) will be Sunday as a weak cold front slides southward. Precip amounts are expected to be light overall.
Aside from the precip potential, there will be a periods of strong winds, especially in the Sierra. Gusty downslope winds are possible down to the mid-slopes of the eastern Sierra tonight through early Sunday. There may be some precip drag, so the high-end gusts near 60 MPH may be tempered a bit. Elsewhere, gusty southwest winds are expected to be much lower. No wind products are expected to be hoisted, as the Winter Weather Advisory, in addition to snow, covers winds impacts.
Beyond the weekend, a high-amplitude ridge will setup over the region bringing a period of tranquil, mild weather. This will last through at least the middle of the week before another, albeit weaker, system brings a quick shot of winds.
AVIATION. For McCarran . Quiet weather can be expected through the weekend. Northeasterly winds could approach 10 knots at times this afternoon, but lighter winds are expected on Sunday. Overnight winds should be from the usual south southwesterly direction at less than eight knots.
For the rest of southern Nevada, northwest Arizona and southeast California . Patchy low clouds in Inyo, Esmeralda, and Lincoln counties will cause mountain obscurations early this morning before finally burning off around mid morning. Otherwise, expect VFR conditions through the weekend. Expect a few areas of breezy northerly winds today, with the strongest winds of 15 to 25 knots with higher gusts in the Colorado River Valley. Winds will be a bit lighter Sunday, but still 10 to 20 knots in the Colorado River Valley.
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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
