.KEY MESSAGES...

* Near-normal temperatures, mostly sunny skies, and afternoon
  northerly breezes will characterize the week ahead until a pattern
  shift over the weekend returns dynamic weather to the region.

.DISCUSSION...through Sunday.

Broad high pressure ridge will dominate the southwestern US
through Thanksgiving day with seasonably mild temperatures and
generally light winds expected. A weak shortwave will move through
the northwest flow aloft Tuesday and Wednesday, resulting in
enhanced pressure gradients across the Great Basin and boosting
northerly winds down the Colorado River Valley, but overall these
winds will be fairly isolated to areas near Laughlin. If planning
to recreate on Lake Mohave this week, check the forecast before
heading out, as wave heights in excess of 1.5 feet could create
hazardous boating conditions for small craft.

By Friday and into the weekend, a pattern shift will take place as
a trough develops across the Great Basin and digs southward.
Confidence is high that a return to cooler than normal and gusty
conditions will accompany this pattern change, while precipitation
potential remains more uncertain. Given the much colder air
associated with this system, low snow levels and post-holiday
travel will be a concern, but confidence in details remains low so
keep checking the forecast as the pattern evolution becomes more
clear.
