.KEY MESSAGES...

- Warming trend continues through the weekend with temperatures
  peaking on Sunday.

- Hot, dry, and gusty conditions leading to increased fire
  weather concerns for Sunday afternoon and evening.

&&

.SYNOPSIS...
Warm temperatures will continue through Monday with the highest
temperatures expected on Sunday. Conditions will remain dry
and winds will be locally breezy each afternoon across Central
Washington. Heat Advisories have been issued across much of the
region for Saturday through Monday evening.

&&

.DISCUSSION...
Above normal temperatures will persist through at least Monday,
likely peaking for most locations on Sunday. Overnight lows will
also remain quite warm. Heat advisories are in effect for much
of the Inland Northwest to account for this heat. Expect locally
breezy winds each afternoon and evening, through the Cascade
gaps eastward to include much of the Columbia Basin and Methow
Valley. With these dry, hot, and breezy conditions, a Fire
Weather Watch is in effect for portions of central WA Sunday
afternoon and evening.

Monday night through Friday: Extended range models indicate the
potential for a system pushing through early next week, with
current timing expected to be from Monday night thru Tuesday
night. This will likely bring cooler temperatures and an
increase in winds. Any precip chances are focused across our NE
zones, but fire weather concerns may be more widespread.
Certainly something to watch in the coming days. Temps rebound
to near to slightly above normal for Wednesday through Friday.
