.KEY MESSAGES...

- Warm temperatures and dry conditions continue, with Friday and
  Wednesday some of the warmest days.

- A weekend cold front will bring dry and breezy conditions and
  the potential elevated to critical fire conditions.

&&

.SYNOPSIS...
Winds will be lighter today, with any lingering breezy
conditions weakening through the day. A weak cold front passing
through on Saturday will bring breezy to gusty winds across
central Washington and a return for increased fire weather
concerns. Little to no precipitation is expected through the
middle of next week. Warm temperatures and dry conditions
continue into next week.

.DISCUSSION...
 HOT, DRY AND BREEZY CONDITIONS SATURDAY...

Today through Friday: Winds have mostly relaxed today, with wind
gusts 10-20 mph across the forecast area. Later today, high clouds
will move in from the south. Smoke and haze from localized wildfires
may impact some areas through the day, but this will largely depend
on fire activity. A broad ridge setting up just off the PNW coast
will bring warming temperatures through the next couple days.
Moderate HeatRisk will return to the region by Friday, especially
across the Columbia Basin. Moderate HeatRisk impacts all those
sensitive to heat without access to adequate cooling or hydration.

Saturday through Sunday: On Saturday, a trough will usher in a weak,
dry cold front. This will cause an increase in winds, particularly
across the Cascade gaps, Columbia Basin, and Okanogan Valley areas,
where gusts 35-40 mph are anticipated Saturday night into Sunday.
Relative humidity values will drop into the teens, bringing a return
of elevated to critical fire weather conditions. For the Okanogan
Valley, since fuels are ready, we have issued a Fire Weather Watch
on Saturday from 11am-11pm due to winds and low relative humidity.
Main impacts will be that rapid fire spread is likely with any new
or ongoing fires. Wind gusts across the eastern third of Washington
and through the Idaho Panhandle will reach 20-25 mph. Temperatures
will decrease by a few degrees Saturday and Sunday, but will remain
in the low 80s. This trough will provide a low chance of showers to
far northeastern Washington and the Idaho Panhandle for both
Saturday and Sunday midday, with greater chances on Sunday.

Monday through Thursday: After the trough moves through, the broad
ridge will set back up over the west coast and begin strengthening
again. This will increase temperatures and keep conditions dry
through at least the middle of next week. By Tuesday and Wednesday,
temperatures are expected to be in the low 90s, resulting in
Moderate HeatRisk throughout the region. The CPC shows increased
chances of higher than normal temperatures for both its 6-10 and 8-
14 day outlook and is in alignment with the clusters, which show
good agreement in signaling continued ridging and higher heights
over the area. On Wednesday, the hottest day of the warm up, a
surface thermal trough will result in a strong cross-Cascade
pressure gradient, bringing gusty winds back to the Cascade
gaps. This will present a return for fire weather concerns. /AS
