National Weather Service Spokane WA
341 AM PDT Fri Jun 28 2024

.SYNOPSIS...
Mild, mostly dry weather likely Friday, followed by warmer
temperatures Saturday. The next system moves through Sunday, with
more wind and thunderstorms. Mountain showers and seasonal
temperatures will continue through the early week. The forecast
trends warmer and drier by the middle to the end of next week.

&&

.DISCUSSION...
Today and tomorrow: Thanks to an upper level low
over Southeast Alberta, there is a small chance of showers (20%)
to Boundary, Bonner, and Pend Oreille Counties later today.
Otherwise will be a quiet day with high clouds filtering in
through the southwest with high temperatures in the 70s and 80s.
Tomorrow will another mild day in the 80s with plentiful cloud
cover ahead of another weak trough off the Pacific coast. There is
a 20% chance of showers in the Cascades and northern mountains
tomorrow with this wave. High resolution models are hinting at
elevated shower development in the Columbia Basin and moving east
during the afternoon tomorrow. There is a small dry lightning risk
tomorrow (less than 5% chance) with this band of elevated showers
as the boundary layer is very dry and models indicate a band of
250-500 J/kg of MUCAPE in the Blue Mountains and central/southern
Idaho Panhandle. Butler

Sunday through Thursday: Unsettled weather returns to start next
week. Showers and thunderstorms will form over the Cascades,
northern mountains, and ID Panhandle, with modest shear and MUCAPE.
Those with outdoor plans should remain vigilant for changing
conditions. Winds will also increase with gusts of 20 to 30 mph
during the afternoon, decreasing after sunset. Then we repeat
Monday, Tuesday, Wednesday, and Thursday; high temps in the 80s,
increasing winds in the afternoons, and showers and thunderstorms
over the higher terrain. The chance of showers and thunderstorms
will decrease slightly each day with most contained along the
Canadian border by Thursday. Models are hinting at a warm up late
next week with temperatures warming up above normal, so stay tuned to
the forecast. /KM
