Synopsis...
a warm, summery and mostly dry Summer pattern will continue
through the work week. However, there will be a chance for showers
and thunderstorms near the Canadian border through Wednesday.
High temperatures in the 90s will be common for nearly all towns
this week with a cool down expected next Sunday. Gusty winds will
accompany this cool down...especially across the Columbia Basin
and Cascade gaps.

Discussion...
update: showers and thunderstorms continue this evening around the
Methow and Okanogan valleys as well as the north portion of the
Okanogan Highlands. With the loss of surface heating these storms
should gradually weaken this evening. However plenty of mid level
moisture and instability exists with the 0z NAM showing 0-6km most
unstable cape values of 500-1000 j/kg overnight in Okanogan County
with 300-600 j/kg from the Waterville Plateau northeast across the
Okanogan Highlands, NE mountains, and the north Idaho Panhandle.
The one missing piece for nocturnal thunderstorms is strong
lift...with just weak lift over the area ahead of a wave
approaching the area. Best chances will be in the northern
Okanogan Valley and in the mountains north of the Methow Valley
where isolated thunderstorms was added for the overnight hours.
Overall there is enough instability to at least keep a mention of
scattered showers in the forecast for the Okanogan and Methow
valleys, north Cascades, and Okanogan Highlands with isolated
showers extending south onto the Waterville Plateau, and as far
east as the NE mountains and the north Idaho Panhandle. Jw

Aviation...
00z tafs: isolated thunderstorms along the east slopes of the
Cascades are expected to dissipate this evening with the loss of
daytime heating but elevated showers may linger tonight over the
northern mountains near the Canadian border. Storms are not
expected to impact any of the taf sites but will be watching keat
given close proximity to the Cascades. Scattered showers and
thunderstorms will redevelop Tuesday afternoon over the northern
mountains...mainly near the Canadian border. Jw
