.DISCUSSION...through Saturday.

Lingering moisture will help to fuel isolated showers and
thunderstorms in Mohave County and the Eastern Sierra this
afternoon. In order for precipitation to make it to the surface, it
will have to overcome the dry lower-levels of the atmosphere. Any
convection that does develop this afternoon will dissipate with the
loss of daytime heating after sunset. A low pressure system will
push into the Pacific Northwest on Monday, resulting in dry
southwesterly flow aloft, which will slowly scour moisture out of
the area. While moisture will be pushed off to the east, it will
happen slowly enough that Mohave County will see chances for
isolated showers and thunderstorms each afternoon through the middle
of the week.

As the aforementioned low pressure system pushes into the Pacific
Northwest tomorrow, we will see breezy southerly winds pick up
across southeastern California and southern Nevada on Monday and
Tuesday. These winds combined with the drying trend will result in
elevated, but not quite critical, fire weather concerns each
afternoon. In addition to dry and breezy conditions, the lower 500
mb heights associated with this trough will result in cooler than
normal temperatures across our forecast area. Temperatures will
remain a few degrees cooler than normal through the end of the week.
