Area Forecast Discussion National Weather Service Las Vegas NV 230 PM PST Fri Dec 13 2019
SYNOPSIS. Pacific systems will bring high clouds, gusty winds, and precipitation chances to portions of the region through the weekend. High pressure will set up over the region early next week with dry conditions along with slightly below normal temperatures. Another system is forecast to move through the region during the late half of next week bringing a return to unsettled weather.
SHORT TERM. through Sunday night.
As of early afternoon, downslope winds in the Sierra have been relatively minor with a few gusts over 50 mph recorded. All signs are still pointing to the potential of strong winds reaching the western portions of the Owens Valley with the greatest threat expected now through 5pm. There are a few showers starting to impact the higher Sierra and these showers are expected to increase over the next few hours. As this occurs the threat of downslope winds will decrease as additional spillover occurs. Snow amounts in the higher elevations of the Sierra will likely be over a foot, but in areas 7000-9000 feet we are generally looking at snow totals generally under 6 inches.
Upper level trough will move into the region Saturday bringing gusty west winds to portions of the Mojave Desert. Strongest winds will likely occur along the I-15 corridor in San Bernardino County Saturday afternoon and evening with gusts over 40 mph possible. Have gone ahead and issued a wind advisory for zones 523 and 524. Westerly wind are not expected to reach advisory levels in southern San Bernardino County Saturday, but as the winds turn northwest behind a cold front the winds are expected to increase significantly, especially in the Morongo Basin Saturday night. At this time did not issued an advisory for that area, but it's possible one may be needed.
A cold front will push south across the region Saturday with precipitation spreading south along the front. This front is not particulary strong and moisture will be rather limited. However, Nye and Lincoln will see the better chances of precipitation with the front and it's possible portions of Lincoln County could see a quick burst of snow behind the front. Snow amounts are expected to remain less than a couple of inches as this front will move through fairly quick. Southern Nevada will be on the western fringes of the precipitation, but a few showers will be possible Saturday evening and overnight as the front moves through the area. Amounts will remain light and most areas will see a Trace or less. The front will slow down late Saturday and Sunday with shower chances remaining in place through much of Sunday across northwest Arizona. Snow levels will generally remain around 6000 feet, but rain and snow amounts will remain light.
System will exit the area late Sunday with a drier northwest flow. Cooler temperatures are also expected with highs on Sunday dropping about 5-8 degrees.
LONG TERM. Monday through Friday. The long term period starts with high confidence with a ridge of high pressure building in behind the disturbance(s) of the short term. By midweek, model consensus erodes quite a bit. While decent agreement exists in bringing a pacific system across the region later in the week, significant timing and to a lesser extent, strength differences exist. The GFS family is the quickest of the camps, bringing the trough ashore on Wednesday, leaving the region in it's wake by Friday, with the ECMWF almost 24 hours slower. In any case, more unsettled weather is expected by the middle to late week next week.
AVIATION. For McCarran . Light winds following close to typical daily trends along with periodic high clouds will continue through Saturday morning. Winds will increase out of the southwest Saturday around noon, with gusts up to 20 knots possible. A cold front will push through Saturday night, bringing a push of gusty north winds, vicinity shower chances, and ceilings crashing to 5-7 kft. Frontal edge will arrive between 04z-06z tomorrow evening.
For the rest of southern Nevada, northwest Arizona and southeast California . LLWS in the Owens Valley and obscuration of the Sierra crest will continue through Saturday morning. Gusty winds will increase across the western Mojave desert Saturday; gusts at KDAG may reach 40-45 mph Saturday afternoon as a weather disturbance passes overhead. Elsewhere winds will be lighter, but south to southwest winds will develop ahead of a cold front. The cold front will move through the Great Basin Saturday afternoon and exit the Mojave Desert early Sunday morning. Gusty north winds and a period of lower ceilings between 5-8 kft are expected with the frontal passage.
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.
