Area Forecast Discussion
National Weather Service Spokane WA
959 PM PDT Sun Aug 20 2017

.SYNOPSIS...
High clouds will clear overnight. Skies should be favorable for
viewing the eclipse Monday morning, however there may be some
smoke in the northern valleys. Tuesday and Wednesday will be quite
warm with afternoon temperatures in the upper 80s to upper 90s.
A vigorous cold front passage has the potential to produce
thunderstorms Wednesday night into Thursday, mainly over the
North Idaho Panhandle. This will be followed by gusty west winds
Thursday.

.DISCUSSION...
Evening update sent to lower temperatures for many locations across
Ern WA and N ID. Light winds and clear skies will allow for good
radiational cooling tonight. Many sheltered valleys were in the
low to mid 40s this morning and are running within a degree or two
of compared to this hour last night. Cloud cover forecast still
looks on track for Monday. The opaque band of high clouds that
was over the region today is clearing to the southeast. High
pressure is strengthening and despite some high clouds spilling
over the ridge into southern BC and N WA, this activity appears
thin and should not obstruct the eclipse set to begin in less than
12 hours. Wildfire smoke will be the main wildcard tomorrow for
any sky obstructions. /sb

.AVIATION...
06Z TAFS: Smoke will continue to impact northern WA and ID
valleys, but confidence is low whether it will get into the main
TAF terminals. Otherwise looking for mostly clear skies with thin
cirrus spilling in from the north on Monday. Winds will be light
and generally terrain driven but may weaken or reverse briefly
during the eclipse 16-19Z. /sb
