.KEY MESSAGES...

  to the region to start the week.

  winds and cooler temperatures later in the week.

.DISCUSSION...through Saturday.

Today will be the warmest day of the week with afternoon
temperatures topping out around 10 to 15 degrees above normal and
multiple daily records at risk (for more information regarding
exactly which records are in jeopardy, see the CLIMATE section
below). A low pressure system will begin to approach the region
today, resulting in gusty westerly winds picking up across the
Eastern Sierra and the western Mojave Desert. The Wind Advisory for
the western Mojave Desert will go into effect at 10 AM this morning
and will continue through Monday night. his system will move through
the area on Monday, bringing more widespread gusty westerly-to-
southwesterly winds to the region with breezy northwesterly, post-
frontal winds expected on the back side of the low. As this system
moves through, 500 mb heights will begin to fall and temperatures
will cool slightly. In addition to increasing winds and decreasing
temperatures, this system will also bring a 20 to 50% chance of
showers to the southern Great Basin and the eastern Sierra.
Precipitation will be light with totals under 0.10 inches. Due to
minimal precipitation amounts and high snow levels, winter impacts
are not expected with this system.

Weak ridging will set up over the region on Tuesday and Wednesday,
resulting in a brief lull before another system drops into the
region from the Pacific Northwest later in the week. This second
system will bring another round of gusty winds and cooler
temperatures to the region during the second half of the week. Given
the inland trajectory of this system widespread precipitation is
not expect, with precipitation chances currently limited to the
Great Basin.
