.KEY MESSAGES...



* Outside of breezy northerly winds in the Colorado River Valley, 

  dry and mild conditions along with warmer than normal temperatures 

  will continue into next week.



* Moisture moving into central California midweek may bring some 

  high elevation snow to the Sierra in northern Inyo County from 

  Wednesday onward.

.DISCUSSION...through next Friday.



Breezy north winds will linger down the Colorado River Valley for a 

few more days, with afternoon gusts peaking in the 20 to 30 mph 

range each day. These increased winds will also result in choppy 

waters between Laughlin/Bullhead City and Needles, and marine 

interests in this area should continue to exercise caution. 

Otherwise, weather across the region will remain dry and mild 

through the first part of next week. Near to record warm 

temperatures will continue today (see the climate section below for 

more details). A series of shortwave troughs embedded within the 

upper-level flow will move through the region over the weekend, 

bringing periods of increased cloud cover. This cloud cover, along 

with lowering 500mb heights, will allow temperatures to decrease a 

few degrees. However, even with this decrease, temperatures will 

remain well above normal through next week.



By the second half of next week, both the ECMWF and GFS ensembles 

show a moderate atmospheric river event bringing increased moisture 

levels into central California. While most of this moisture is 

expected to be intercepted by the Sierra, some light snow 

accumulations will be possible along the Sierra crest in northern 

Inyo County. At this time, amounts are expected to be light and no 

significant impacts are anticipated, but details should become 

clearer as we move into next week.
