.SYNOPSIS...Today will be the warmest day of the week with
temperatures gradually decreasing each day through Friday. Breezy
southwesterly winds will pick up across the area on Wednesday and
Thursday as a shortwave rolls through the Great Basin. Our next
impactful system will arrive over the weekend, bringing gusty
winds and cooler than normal temperatures to the region.

&&

.SHORT TERM...through Thursday.

Today will be the warmest day of the week with temperatures topping
out around 3 to 8 degrees warmer than normal. Temperatures will
decrease a few degrees each day on Wednesday and Thursday as a
shortwave rolls through the Pacific Northwest and Great Basin,
resulting in falling heights across southern Nevada, southeast
California, and northwest Arizona. In addition to a gradual decrease
in temperatures, we will also see breezy southwesterly winds pick
up across the region in response to a tightening surface pressure
gradient. Dry conditions will persist through the end of the work
week as any precipitation associated with this shortwave will
remain to the north of our forecast area.


.LONG TERM...Friday through next Tuesday.

Heading into the weekend, we continue to watch the evolution of a
weather system as it pushes into the northwestern United States.
Guidance is coming together somewhat regarding the broad
characteristics of the low, but there remains quite a spread
regarding details of the low such as its strength, moisture
content, trajectory, and timing. Solutions are starting to favor a
closed low upon moving inland, with the ECMWF means indicating a
negatively- tilted trough will extend southward through our
forecast area as this occurs. Moisture increases to 120-150
percent of normal (normal being around 0.30" for this time of
year).

As the trough axis pushes through the forecast area, expect gusty
southwest winds to pick up on Saturday, followed by gusty northwest
winds on Sunday. Will continue to consider the need for wind
headlines as we get closer. In addition to gusty winds, temperatures
will drop back below-normal, with high temperatures in the 70s for
Las Vegas heading into the next work week. Mentionable PoPs continue
to remain confined to the southern Great Basin, with 10-20% PoPs
reaching as far south as northern Inyo, northern Esmeralda, northern
Nye, and northern Lincoln counties Saturday and Sunday.
