the early afternoon. Highs will start a upward trend from
Monday. Highs for the day will be in the 70s. Overnight lows
will be in the 40s to low 50s.

Wednesday and Thursday: Winds will be main concern Wednesday
and Thursday. For Wednesday, South to North winds will bring
breezy conditions across the Waterville Plateau and Okanogan
Valley. Sustained winds will be in the teens with gusts up to 25
mph. Thursday will begin the breakdown of the stable pattern as
a trough begins to press into the region from BC/Alberta. It
will bring a tightening pressure gradient and stronger winds.
For Thursday, westerly winds spread across the Basin with
sustained in the teens with gusts up to 30 mph. Locally higher
winds are possible over the Waterville Plateau with gusts up to
40 mph. Blowing dust could be a concern in the area. Other
impacts include choppy waters and fire concerns that missed on
last weekends rain. These will be the warmest days of the week.
Highs will climb back into the upper 70s and low 80s. Overnight
lows will be in the upper 40s and 50s on Wednesday night.
Thursday night will be cooler in the 40s. Sheltered areas in the
northern valleys could dip into the upper 30s.

Friday and Saturday: A Low will push through the region as the
trough continues to deepen over the Pacific Northwest. A weak
wave moves across Thursday night into Friday, then the Low digs
down the coast Friday night into early Saturday before swinging
inland Saturday afternoon into Sunday. A few showers are
possible around the mountains with the first wave, but better
chances expand out Friday night into Saturday, before starting
to retreat to the mountains and wane Sunday into Monday. Some
moderate rains are possible around the mountain zones Saturday,
with lighter amounts elsewhere. Embedded t-storms are possible
and may produce locally higher amounts. Saturday is also
forecast to be another breezy day. Temperatures cool to the
upper 60s and 70s Friday, mostly 60s and localized low 70s
Saturday, before moderating into Sunday and Monday. Lows will
continue to be in the 40s. Sheltered areas in the northern
valleys could dip into the upper 30s. /JDC
