.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 00Z Forecast Package...Wind has 

underachieved today, and should remain light easterly until 

switching to light westerly after sunset. Overnight, northerly winds 

are slightly favored (~60%) to reach the terminal, with sustained 

speeds of about 8 to 10 knots. If the winds reach the terminal, a 

few stronger gusts cannot be ruled out. Winds should shift to 

northeasterly by noon and remain there until switching to northwest 

or west around sunset. Mostly clear skies.



For the rest of southern Nevada, northwest Arizona and southeast 

California...For the 00Z Forecast Package...Expect northerly breezes 

to 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

procedures.
