Debris Flow in Washington, June 10, 2016

Area Forecast Discussion
National Weather Service Spokane WA
1050 AM PDT FRI JUN 10 2016

.SYNOPSIS...
Cooler, breezy and showery weather will impact the Inland
Northwest today through the weekend. A weak warming trend is
anticipated for early next week, but temperatures will remain
below normal with a continued unsettled and occasionally breezy
pattern.

&&

.DISCUSSION...
The slow moving cold front is stuck over extreme eastern
Washington this morning with steady light to moderate rain mainly
east of line from Republic to Harrington to Washtunca and into
north Idaho, where it will be cloudy, stable and cool.
Temperatures will struggle through the 50s to lower 60s. West of
this line, partial clearing will take place with cumulus forming.
Instability will increases as the cold upper low moves steadily
inland. Small showers are already forming in the Wenatchee valley
with brief downpours and small hail. The threat of thunder will
increase over the northern Cascade mountains this afternoon. The
upper low will continue to lift northeast, across the northern
Cascades and into southern BC - which will keep the threat of
convections going along the Canadian border overnight. /rfox.

.AVIATION...
18Z TAFS: A cold front edges across eastern WA/north ID today,
with steady rain lingering over most eastern TAF sites through
21-23Z before drying out. Areas of MVFR cigs and local IFR are
expected and perhaps brief MVFR vis. To the west expect more
isolated to scattered instability showers. A few thunderstorms
will be possible near the Cascades/northern mountains in the
afternoon too. In addition expect locally breezy conditions,
especially near the Cascades/western Columbia Basins. Local gusts
near 25kts will be possible. Expect improving conditions overnight
into Saturday morning with some partial clearing. Isolated
convection may linger through the night near the Canadian border,
while mid to high level clouds will spread into the region. Would
not rule out some patchy fog/stratus in sheltered areas but
confidence is low. /rfox
