  before a slow warm-up begins early next week.

  of the area dry.  A slight uptick in monsoonal moisture across
  Arizona next week will bring some precipitation chances to eastern
  Mohave County by mid-week.

.DISCUSSION...through Thursday.

A closed 500mb low off the central California Coast continues to
move off to the east-northeast early this afternoon.  Over the
weekend, the low will weaken and be absorbed into larger-scale
troughing across the western US.  The main impact for our CWA will
be a continuation of lower-than-normal heights, which in turn will
keep temperatures several degrees below normal in most areas through
Sunday.  Once the low is absorbed, heights and temperatures will
increase slightly, although readings are only expected to return to
near seasonable norms by early next week. Long-range ensemble
guidance indicates the possibility of another upper-level low
developing along the central California Coast by next weekend, which
should help keep temperatures in check across our area.

With the large-scale trough in place across the west, most of the
CWA will remain in dry southwest flow, limiting, but not
eliminating, precipitation chances.  With the low moving across
central California today and tomorrow, isolated thunderstorms will
be possible in the higher elevations of the Sierra, generally north
of Mt. Whitney.  Any storms that do develop are expected to remain
over the mountains and not directly impact the Owens Valley.  Later
in the week, strong high pressure over the central plains will
spread west, allowing an increase in monsoonal flow across Arizona.
Most of the increased moisture will remain east of the CWA, but PWAT
values will increase to .70" to .80" across far southern and eastern
Mohave County by Tuesday, leading to increased chances of
thunderstorms in these areas. Currently, the chance of precipitation
in the Las Vegas Valley is minimal; however, the exact progression
of the high next week will determine how far west the precipitation
eventually spreads.

Winds in the Owens Valley will follow typical diurnal directional
trends with breezier up-valley winds picking up during the
afternoon and evening. Elevated westerly winds will continue
