.DISCUSSION...through Sunday. Early afternoon satellite loop showed 

areas of cirrus zipping by in fast west northwest flow aloft. 

Surface obs showed breezy southwesterly winds, with the strongest 

gusts of 40 to 50 mph on the eastern slopes of the Sierra, and 

temperatures averaging a few degrees warmer than 24 hours ago.



The strongest gusts in the Mojave Desert thus far have been 35 to 40 

mph in the Barstow area. Guidance is in strong agreement that desert 

winds will settle down between sunset and midnight as daytime 

heating and deeper mixing are lost.



The axis of the deep mid-level trough passing by to our north will 

move east of us tonight, allowing surface winds to reverse to 

northerly. Since the parent trough is moving eastward rather than 

southward, strong wind potential will be limited and mostly driven 

by surface pressure gradients, which peak on Tuesday as surface high 

pressure strengthens over the northern Great Basin. Peak gusts then 

could reach 40 mph in the Laughlin/Bullhead City/Davis Dam area, 

possibly requiring a Lake Wind Advisory if the forecast gradient 

does not weaken by tomorrow. Weaker and less widespread winds are 

expected Monday and Wednesday due to weaker pressure gradients, with 

peak gusts around 30 mph in the Laughlin area and less areal extent 

of gusts over 20 mph.



Aside from the aforementioned winds, quiet weather is expected for 

the upcoming week as high pressure builds in the wake of the 

departing trough. Dry weather is expected, with areas of passing 

high clouds, and temperatures about five to 10 degrees above late 

October/early November normals.

.AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds 

will be the main concern through Monday. A weak cold front will move 

through the valley overnight, but at this time, winds are not 

expected to show much of a response. Expect southwest winds to 

diminish around 10z with winds becoming light and variable through 

17z. It is possible that a period of northwest winds up to 7 knots 

will occur during that time, but it is expected to remain brief. 

After 17z, winds will become more northeast with the most likely 

scenario is for sustained speeds around eight knots, but a few gusts 

around 15 knots cannot be ruled out. Winds should go light and 

variable around sunset Monday. VFR conditions will prevail.



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 06Z Forecast Package...Winds will be the main 

concern through Monday. Gusty west winds will prevail around KDAG 

through  A weak cold front will push south through the southern 

Great Basin and the northern Mojave Desert tonight into Monday 

morning, shifting winds to a north to northeasterly direction. The 

strongest gusts of 15 to 20 knots will likely be in the Colorado 

River Valley, with gusts around 15 knots or less elsewhere. VFR 

conditions will prevail.
