Synopsis
The weather for the weekend will be quite warm. Afternoon
temperatures on Saturday will likely reach the mid 80s to low 90s.

Sunday and Monday will be even warmer with most lowland areas
reaching the 90s. A return to cooler, more average temperatures
are expected by the middle of next week, with breezy conditions
possible late Monday and Tuesday.

Discussion
Tonight through Saturday night: the inland northwest will reside
on the eastern periphery of an amplifying ridge of high pressure.

This will keep a dry northwest flow into the region promoting
mostly clear skies and subtle warming trend. Over the last few
days, the european forecast model was indicating a stronger wave
digging into the region bringing a threat for showers into the
idaho panhandle Friday. Trends over the last two runs have backed
off on this wave now coming in line with the drier north american
models giving more confidence to the drier forecast solution. Winds
at the surface will remain from the north northwest then north
to northeast Friday Saturday. The afternoon hours will feature
occasional gusts to 20 mph. Temperatures will start off near
seasonal averages this afternoon and warm a few degrees each day
returning to the mid 80s to lower 90s by the start of the weekend.

Sb
Sunday and Monday: this will be the warmest period of the week as
the high pressure ridge continues to build in. The ridge axis
will move into washington on Sunday, when 850 mb temps around 23 c
suggest widespread upper 80s and low 90s. The axis crosses
eastern washington on Monday and temperatures increase 4-5
degrees. Models have been increasing Monday's temperatures
in recent runs, and it's now likely we'll see highs in the mid to
upper 90s, with some areas in the deep basin even breaching the
100 degree mark. The ridge begins to move out on or about Monday
evening, with flow becoming southwest on Monday which will begin a
regulation in our temperatures, but also increase winds late
Monday as the cross cascade pressure gradient tightens.

Tuesday through Thursday: for those who aren't fans of Monday's
excessive heat, Tuesday will be a relief. With the ridge being
pushed out, temperatures will be dropping around 10 degrees;
closer to normal but still above average for late june. Winds will
be gusty on Tuesday as well, and given the substantial curing of
the fine fuels in the basin that is likely sat-mon, concern for
grass fire spread will be elevated. Beyond Tuesday models diverge
significantly on how the upper flow pattern will evolve. Bw

Aviation
12z tafs: dry northwest flow will promote mostly clear skies
through 12z fri. Winds will be lighter compared to the last few
days. Expect occasional gusts to 20 mph at spokane and couer d
alene... Otherwise winds will be around 10kts or less and becoming
more terrain driven at keat. Sb

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
