.DISCUSSION...through Monday. Midday satellite loop showed clear 

skies areawide. Surface obs showed temperatures averaging a couple 

of degrees cooler than 24 hours ago and areas of breezy northerly 

winds.



The winds will be the main concern through Wednesday. As expected by 

previous shifts, the trough axis has now moved to our east, bringing 

in the northerly winds on its back side. Thus far, the strongest 

gusts have been on the NNSS, but this will change tonight and 

Tuesday. As surface high pressure strengthens over the northern 

Great Basin, the north-south pressure gradient intensifies, which 

will support increasing north to northeast winds beginning tonight 

and peaking on Tuesday. KELY-KEED gradient should peak around 12-14 

mb, but upper support will be lacking, so winds around 25 mph with 

gusts around 40 mph look probable, strongest around Bullhead City as 

is usually the case with north winds. Thus, hoisted a Lake Wind 

Advisory for Tuesday from Lake Mead through Lake Havasu. The surface 

high will weaken Wednesday, and the gradient will flop over to more 

of a northeast-southwest orientation, so winds will weaken.



Otherwise, high pressure aloft was already building over the eastern 

Pacific this afternoon and is expected to be in control of our 

weather at least through the weekend, if not longer. This will keep 

our area dry with temperatures about five degrees above normal for 

late October/early November.

.AVIATION...For Harry Reid...For the 18Z Forecast Package...Wind 

will be the concern. Northeasterly winds should reach the terminal 

by noon, and the best chance for 10+ knots is between 19z and 22z 

with a 40% probability. If they do exceed this threshold, the 

direction will be between 010 and 070. Winds should weaken and turn 

back westerly around sunset, if not before. Another push of north to 

northeast winds could reach the terminal overnight, but the more 

likely scenario (~60% chance) is for these winds to affect Nellis 

AFB and areas down the Colorado River. Tuesday will likely see the 

strongest northeasterly winds at the terminal, with sustained speeds 

around 10 knots beginning in the morning. Stronger gusts cannot be 

ruled out. Mostly clear skies.



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 18Z Forecast Package...Expect northerly breezes 

through this afternoon, with the strongest gusts of 20 to 30 knots 

in rural areas of Esmeralda and Nye counties. Northerly winds will 

increase overnight and persist through Tuesday, with the strongest 

gusts of 30 to 40 knots expected in areas of north-south oriented 

terrain, such as the Colorado River Valley and Death Valley. Mostly 

clear skies.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report

any significant weather or impacts according to standard operating
