Smoke and haze is expected to continue over the weekend. The
threat for showers and thunderstorms will increase this evening
and into Sunday. Gusty outflow winds are possible near any
thunderstorms. Additional rain chances will arrive next week
with cooler temperatures.
&&
.DISCUSSION...
Tonight through Sunday: The Low is tracking off the coast of
southern Oregon and is pushing a shortwave through northern
Oregon. The wave will continue to move north through tonight.
It will begin to impact the Inland Northwest in the next couple
of hours. It will bring light showers and isolated
thunderstorms. Confidence is fairly low on which areas will be
impacted by the thunderstorms. One concern are the winds ahead
of the wave. Some models are showing winds sustained in the
teens with gusts near 30 to 35 MPH. While the shower chances
increase across the region, the amounts are not expected to be
much for the most of the lowland locations with a few hundredths
at most. It will hopefully bring better air quality as the rain
and wind mix out the smoke.
Monday through Friday: The Low will slowly move South of the
Inland Northwest through the period. It will continue to pump
moisture and bring widespread shower chances through the
Friday. Precip amounts range from a tenth or two for the
lowlands and a quarter to 3 quarters of an inch for the higher
terrains. Ensembles support isolated thunderstorm threat. With
this pattern, temperatures will moderate to season normals.
Highs will be in 70s and low 80s. Overnight lows will be in the
50s. /JDC

.AVIATION...
18Z TAFS: Visibility restrictions due to smoke will continue
regionwide. Visibility is expected to range from 2-6 miles for
most of Central and Eastern Washington and north Idaho, but
areas near fires including Colville will see visibilities as low
as 1 mile. Latest models have slowed down the weather
disturbance moving northward through the day today with
thunderstorms not expected to develop around KEAT, KMWH, KLWS,
and KPUW until after 02Z. Gusty outflow winds to 40 mph will be
possible near any storms.
FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS:
Low confidence in precise visibilities at the TAF sites from
haze and smoke. There is moderate confidence for scattered
thunderstorms 00-06z and beyond.
-----------------------
Confidence descriptors:
Low - Less than a 30 percent chance
Moderate - 30 to 70 percent chance
High - Greater than a 70 percent chance
