Area Forecast Discussion
National Weather Service Las Vegas NV
242 PM PDT Mon May 6 2024

.SYNOPSIS...Gusty north-northwest winds expected today through
Wednesday across the forecast area. Temperatures will warm through
Tuesday before dropping once again on Wednesday and then gradually
warming through the rest of the work week into the weekend.
&&

.DISCUSSION...Today through next Monday.

The system that brought gusty winds to the region last weekend will
continue to push eastward. As it pushes east, it will dig a longwave
trough across the entire United States. This set up will place us
beneath a dry northwest flow aloft. However, this pattern allows
shortwaves to ride through the Desert Southwest, often bringing
strong gusty winds along with it.

This will occur on Tuesday and Wednesday. A shortwave will ride
along the northwest flow, resulting in gusty north-northwest winds
across the southern Great Basin Tuesday afternoon, then spreading
southward and focusing along the Colorado River Valley on Wednesday.
Winds along the Colorado River Valley will also be aided by
topographic enhancement, which could result in very localized gusts
above 40 mph - particularly near Bullhead City / Laughlin, which
would impact Lake Mohave. As such, expect dangerous boating
conditions, especially for small craft on Wednesday. This shortwave
will usher cooler air into the region, resulting in a temperature
drop to below-average once again on Wednesday.

Ensemble means indicate that the aforementioned area of low pressure
over the central United States will retrograde, with a weak blocking
pattern anticipated over the Desert Southwest as a growing ridge of
high pressure builds in the eastern Pacific. As such, expect breezy
afternoons through the remainder of the work week. Regardless,
heights will rise over the area, resulting in an increase in
temperatures going into the weekend. Desert valleys can expect high
temperatures in the low-to-mid 90s by the end of the weekend.
