.KEY MESSAGES...

* Warming and dry conditions are expected through early this
  week, with above normal high temperatures by Sunday and Monday.

* The next system to impact the region arrives midweek, bringing
  cooler temperatures, another round of gusty winds, and shower
  chances to the southern Great Basin.

.DISCUSSION...through next weekend.

Mostly clear skies prevail across the region this afternoon as
high pressure begins to rebuild across the Southwestern US. This
high pressure ridge will continue to sharpen across the Four
Corners region through early next week allowing for a continued
warming trend, with afternoon highs climbing several degrees above
normal by Sunday afternoon, and warming further on Monday.
Otherwise, some minor afternoon breezes will persist around the
Lake Mohave and and Havasu areas today but will gradually ease
tonight and tomorrow.

The active weather pattern will resume by Tuesday and Wednesday
of next week as a deep cutoff low approaches the West Coast. This
will result in an increasing southwesterly flow aloft Tuesday and
surface winds will become gusty Tuesday afternoon and overnight
as the cutoff low moves into the Great Basin. Rain and mountain
snow chances will also correspondingly increase as the weather
system moves through in the Sierra and southern Great Basin.
Cooler temperatures will follow midweek onward with only gradually
rebounding temps expected by next weekend.
