.DISCUSSION...through the weekend. 



Quiet conditions dominate the region this afternoon though breezy 

north winds continue. These winds are most notable near Lake 

Mohave and Laughlin, where the winds have been gusting in the 

45-50 mph range as winds funnel down the river valley. Winds will 

gradually subside tonight as pressure gradients ease. Otherwise, 

another cool night is in store - especially for locations where 

the winds drop off quickly. Barstow-Daggett dropped to 32 this 

morning, marking their first freeze of the winter season, and 

parts of the Las Vegas Valley dropped into the 30s. Similar low 

temperatures are expected again tonight, though some increasing 

cirrus will begin moving in late tonight which may moderate the 

temperature curve slightly. 



On Tuesday, high clouds will begin to stream in from the south

ahead of a low pressure system lurking off the Baja Coast. This

system is on track to spread rain chances into the Mojave Desert

Wednesday that will continue into New Years Day as a shortwave

lifts into the Great Basin. While moisture will be rather abundant

given the subtropical origin, dynamics will be fairly weak. This

lends to the likelihood of generally light rainfall expectations,

but enough rain to dampen NYE festivities and result in some wet 

roadways. Snow levels will be quite high, generally above 9500

feet areawide on Wednesday, and only dropping very slightly on

Thursday. This will limit any snowfall impacts to all but the

highest peaks in the forecast area.  Additional troughing along 

the West Coast will keep precip chances going Friday and into the 

weekend, mainly for the Sierra and southern Great Basin.
