.KEY MESSAGES...

* Well above normal temperatures will continue through Tuesday
  before decreasing during the second half of the week, although
  temperatures will remain several degrees above normal.

&&

.DISCUSSION...through next Monday.

Large high pressure ridge over the Southwestern US will keep warm
temperatures locked in today and Tuesday, with afternoon highs
peaking near daily record territory. The ridge will begin to shift
eastward and weaken midweek in response to a shortwave pushing
into the PacNW and northern Great Basin. This will induce a subtle
cooling trend along with increased afternoon breezes. Despite
being cooler than earlier in the week, temperatures will remain
several degrees above normal. Warm and dry conditions will
continue into the weekend with enhanced afternoon breezes possible
again Saturday as a weak shortwave moves through the Great Basin.
