Area Forecast Discussion National Weather Service Las Vegas NV 318 AM PST Sun Dec 15 2019
SYNOPSIS. Light rain and snow showers will gradually dissipate across southern Nevada this morning while persisting across northern Mohave County into the afternoon. Gusty north winds will develop later today ushering in cooler temperatures. North winds will persist within the lower Colorado River Monday and Tuesday along with below normal temperatures areawide. Except for the southern Sierra, the next system looks to be dry but will be associated with considerable cloudiness.
SHORT TERM. through tonight.
Presently, area of showers continues to persist from northern Mohave County westward across northern Clark County/Nevada National Security Site and Death Valley NP. Along the northern Beltway of North Las Vegas and the Moapa Valley have seen a few stations report about a 0.30 tenths of an inch of rain since last evening. However, most rainfall amounts generally a 0.10 of an inch of less. Upper level disturbance crossing southern Nevada and region of upper level divergence will keep this E-W area of showers across southeast Nevada through 8-10 am this morning. The chance for showers will last into the afternoon across northern Mohave County before showers dissipate as upper level disturbance slides east tonight. Some areas of northeast Clark County may see another 0.25 of inch of rain while a 0.25-0.50 an inch is possible on the plateaus of northern Mohave County. As snow levels lower, elevations above 5000 feet in northern Mohave County could see 1-3 inches of new snow, locally higher amounts up to 5 inches at Mt. Logan and Mt. Trumbull.
Wind gusts in excess of 40 mph continue at this hour in San Bernardino County. The wind will begin to gradually weaken after another 3-4 hours. Will let the advisory run its course and update around 6 am this morning. Stronger northwest winds will develop later today in Inyo, Esmeralda and Nye Counties. Those winds look to stay below advisory thresholds.
LONG TERM. Monday through Saturday.
A ridge of high pressure will move overhead Monday and Tuesday providing dry conditions, but north winds will increase, especially along the Colorado River Valley where speeds of 20-30 mph will be possible near Laughlin-Bullhead City. Temps will be running several degrees below normal as a cool air mass holds in place.
Wednesday will bring a quick change in the pattern as a fast moving eastern Pacific Trough swings inland almost directly over our forecast area. However, it appears it will be too moisture starved to produce any noticeable effects except isolated snow showers over the southern Sierra. It lifts away by Thursday as another ridge moves over the region for continued dry and tranquil weather through Saturday.
AVIATION. For McCarran . Some lower CIGS around 5 Kft along with a few showers possible early this morning, then breezy north winds behind a cold front for much of the day with clearing skies. Icing is possible above 8 Kft with initial shower activity, then low-level turbulence with the northerly winds. Wind speeds subside around sunset, with lingering northerly winds possible for Monday.
For the rest of southern Nevada, northwest Arizona and southeast California . Showers and associated ceilings and icing hazard should clear the region this morning, leaving northerly winds and low-level turbulence for much of the area - especially down the Colorado River Valley. Westerly winds will likely persist at KDAG. Gusty northerly winds will likely kick up another notch down the Colorado River Valley by Monday morning.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.
SHORT TERM . Pierce AVIATION . Steele LONG TERM . Adair

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.
