Synopsis
Warmer weather will return to the inland northwest with most of
the region climbing into the 90s on Tuesday. The arrival of a
cold front Wednesday afternoon will produce gusty winds followed
by a chance for rain. Temperatures will cool down following
Wednesday's front with a return to highs in the 80s Thursday
through the weekend.

Discussion
Tonight and Tuesday: dry southwest flow ahead of a low pressure
system will bring even warmer temperatures into Tuesday under
mostly clear skies. Most towns will reach the lower to mid 90s
with the lewiston area near 100f which is about 10 degrees above
normal. This will likely be the warmest day of the week as a cold
front arrives Wednesday. Jw
Wednesday through Friday... The weather will be quite active through
this period. A deep low pressure system is expected to drag a
robust cold front through the region. The cold front will be on
the cascades early Wednesday evening. The front will track across
the inland northwest and be east of the region around 12z
Thursday. This will bring cooler temperatures gusty winds and a
chance of showers to the forecast area. Moisture increases with
the southwest flow, and it now looks like most areas will see some
rain out of this. The cascade crest and just to the east of the
crest will get a wetting rain. The panhandle with the front and
then up-sloping behind the front could also see a wetting rain.

In between not so much with only a couple of hundredths expected.

This brings us to the next challenge. A very dry sub-cloud layer
will result in rapid evaporation of the rain (virga) and this will
keep rain amounts to a minimum. The rain cooled air will cause a
gust front to move through the columbia basin and points east.

Winds behind the front will remain elevated through Thursday
morning, then should decrease through the afternoon. Temperatures
will be cooler across the western zones with places like
wenatchee, moses lake, and omak dropping 6-10 degrees, but
temperatures only cooling a few degrees across the eastern zones
and likely because of cloud cover. Thursday will be cooler across
the entire forecast area with high temps on the cool side of
normal
the trough kicks eastward Thursday night with westerly flow over
the region on Friday. This will allow temperatures to rebound back
to near normal, dry conditions and light southwest winds. Tobin
Saturday through Monday: a zonal flow will set up over the region
during this period. There is very little moisture associated with
this pattern keeping the chances of precip near zero. Perhaps the
only impact will be Saturday afternoon with winds. The upper
level jet will be over washington and models are carrying 850mbs
winds into the mid 20kts. Outside of that, weather is expected to
be fairly quiet for the rest of the period. Highs are expected to
be in the 80s across the region with lows in the 50s. Jdc

Aviation
00z tafs: high pressure aloft will promote mostly clear skies
andVFR conditions. Winds will be light and generally under
10kts. Exception will be at keat where typical diurnal winds
from the northwest will be near 10kts. Sb

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.
