Area Forecast Discussion National Weather Service Las Vegas NV 259 AM PST Sat Dec 14 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. A dry trough will pass across the region later in the week with more high clouds and breezy winds.
SHORT TERM. through Sunday night.
Little changes to the short term. The focus remains passing trough and attendant cold front. As the trough approaches today, the belt of southwesterly winds will likely remain just south of Las Vegas. Bumped temps a little downward for Las Vegas and areas northward based on the lack of mixing and likely insolation inhibition from clouds. A weak cold front will sink south to about Las Vegas through the afternoon and evening, then kind of stall out for the night. Additional lift along the front as the upper- level trough axis passes overhead will help develop showers, especially from the Spring Mountains eastward into northwest Arizona. Models vary quite a bit with QPF amounts for any one area given the showery nature, with widespread amounts likely limited to hundreths of an inch, with isolated tenth to two tenths of an inch amounts thrown in.
The cold front makes further progress on Sunday as the upper-level trough departs, with the usual northerly wind concerns down the Colorado River Valley.
LONG TERM. Monday through Friday.
A quiet long term expected with transient ridge of high pressure to start. The mid/late week system still looks on track, with timing differences still evident between GFS and ECMWF, however, with agreement in little of the way of moisture east of the Sierra. Thus, the only impacts are likely to be batches of clouds, and maybe a few afternoon breezes.
AVIATION. For McCarran . Winds less than 8 kts will follow close to typical daily trends along with periodic high clouds today. Ceilings will lower tonight with the approach of a cold front. Can not rule a a light shower in the vicinity of the valley terminals between 08Z and 12Z tonight. North winds will increase behind the cold front Sunday morning while the lower cigs dissipate.
For the rest of southern Nevada, northwest Arizona and southeast California . Potential LLWS in the Owens Valley and obscuration of the Sierra crest will continue through this morning. Westerly winds will continue to increase across the western Mojave desert; gusts at KDAG may reach 35-45 kts. Elsewhere winds will be lighter, but south to southwest winds will develop ahead of a cold front up the Colorado River Valley. The cold front will move south through south central Nevada this afternoon and exit the Mojave Desert early Sunday morning. Can not rule out a light rain or snow shower and lower cigs between 5-8 kft along the cold front in southeast Nevada and northwest Arizona this evening and overnight. Gusty north winds will develop behind the cold front and continue into Sunday.
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.
