Area Forecast Discussion

.KEY MESSAGES...

* Breezy south-southwesterly wind gusts will continue through the
  week with dry conditions and near-normal temperatures.

&&

.DISCUSSION...Today through Monday.

Tightened pressure gradients across the region will continue to
bring gusty south-southwesterly winds to the forecast area in the
afternoons thanks to an upper-level trough across the Pacific
Northwest and a ridge to our east. Expect gust speeds generally
between 25 and 35 mph, though can`t rule out 40 mph speeds in
isolated instances and/or in the higher terrain. Ensembles
continue to show a reinforcing closed low riding along the
California Coast before pushing into the southern Great Basin mid-
to-late week. The resultant instability coupled with 0.75 to 1.25
inches of PWAT over our eastern zones have resulted in increased
PoPs across southeastern Lincoln and northern and eastern Mohave
counties Wednesday and Thursday. Additionally, WPC has painted a
Marginal Excessive Rainfall Outlook over northern Mohave County
for Wednesday and Thursday. Coverage is expected to be isolated,
but storms that form have the potential to be efficient rain-
makers. For locations west of Interstate 15, expect mostly dry
conditions and temperatures near-normal heading into the next work
week.
