Area Forecast Discussion
National Weather Service Spokane WA

.SYNOPSIS...
A ridge of high pressure will persist over the Inland Northwest 
through the week. This will bring mostly clear skies, dry weather, 
light winds with chilly morning temperatures and mild afternoons 
highs. 

&&

.DISCUSSION...
Today through Tuesday: The upper level ridge will continue to
strengthen over the Pacific Northwest through Tuesday. We may see
some thin cirrus from time to time today especially across north
ID, with clear skies expected on Tuesday. Temperatures today will
be around average for this time of the year, or valley temps in
the upper 50s to lower 60s. Then Tuesday we will see about 2 to 5
degrees of warming. Overnight low temperatures will remain cool
for this time of the year with most low elevation locations at or
below freezing. /Nisbet

Tuesday night through Sunday...The upcoming week will continue to
to be dry with generally clear skies or occasionally partly cloudy
with variable high clouds. Winds will be light and temperatures
will gradually increase each day to above normal...in the lower 
to mid 60s during the day by next weekend. Mornings will be 
seasonably cool. This quiet and benign pattern will be compliments
of a mean upper level ridge with axis just off the coast with the
forecast area under the dry northwesterly flow down the eastern 
flank...with the ridge axis occasionally shifting over the region 
especially by the weekend. 

The only mentionable weather issues will be the prospect of
patchy morning fog in sheltered valleys and river bottoms in the
early mornings...and the potential for deteriorating air quality 
later this week as a persistent mid level subsidence inversion 
limits mixing heights and light winds may prove incapable of 
adequately ventilating accumulated smoke and pollutants in the
basin and valleys around the region. This is not a sure bet and
subsequent shifts over the next few days will need to monitor this
potential and coordinate with regional air quality folks before
achieving enough confidence to issue any air quality products.
