.KEY MESSAGES...

- Elevated fire weather risk Sunday afternoon.

- Dry weather pattern continues through next week.

&&

.SYNOPSIS...
Very dry conditions and continued breezy winds on Sunday will
keep fire weather conditions elevated. Temperatures will remain
near to above average for Sunday through much of next week.

&&

.DISCUSSION...

Sunday: Following Saturday`s cold front, temperatures on Sunday
will feel much cooler with highs in the 70s to low 80s. Winds
will shift to the west and north and become breezy through the
Okanogan Valley, Cascade gaps, and western Columbia Basin.
Despite temperatures being lower, much drier air behind the
front will contribute to low relative humidity values in the
teens to low 20s Sunday afternoon. This will keep fire weather
conditions elevated through the afternoon.

As the upper level trough moves across the region, models are
showing enough moisture and instability across the North
Cascades/Pasayten Wilderness to support a 15 to 20 percent
chance of showers. Instability will be rather weak, but an
isolated cell strong enough for a couple strikes of lightning is
not out of question.

Monday through Saturday: Going into the work week, a
strengthening ridge offshore and a broad upper level trough from
the northern Rockies to the northern Plains will keep the
Inland Northwest under northwest flow flow through the week.
Clear skies Monday morning and then again Tuesday morning will
allow for strong radiational cooling with the northern valleys
cooling into the upper 30s overnight. The NBM is giving the
northeast valleys a 20-40 percent chance for temps of 37F or
below. Weather looks to be generally quiet for the week with
temperatures gradually warming. Embedded waves in the northwest
flow will bring occasional shower chances across north Idaho
along the Idaho/Montana border with widespread afternoon breezy
winds. Winds on Friday are beginning to stick out as the next
period to monitor with the NBM showing a 30 to 60 percent chance
for wind gusts above 40 MPH across central Washington. /vmt

.AVIATION...
12Z TAFS: VFR conditions are expected to continue through the
TAF period. Breezy winds will develop again this afternoon over
Central Washington with sustained speeds between 10 to 20 knots
