.DISCUSSION...Today through Saturday.

The downward trend in moisture continues as the low over southern
California draws dry air into the region. Storms today will mainly
be confined to the eastern Sierra, White Mountains, and high terrain
in northwestern Arizona. Gusty outflow winds and small hail are
possible with these storms, but overall precipitation should be
light. Activity will pick up in the afternoon and decrease in the
evening with a lost of surface heating. An upper level low digging
into the Pacific Northwest will help to increase dry southwesterly
flow early in the week, but lingering moisture leaves the potential
for isolated thunderstorms through Wednesday, mainly in northwestern
Arizona.

Much drier air along with breezy conditions are expected Monday
through Wednesday, raising fire weather concerns. There could be
some areas of elevated fire weather conditions across Nye and
Lincoln counties on Monday. However, fire weather headlines do not
appear necessary at this time. Temperatures will increase as
moisture and cloud cover decrease, but highs still remain a few
degrees below seasonal averages. HeatRisk remains in the minor to
moderate categories, levels that primarily affect those who are
sensitive to heat.
