Synopsis
Today will be cool with most lowland areas in the inland northwest
topping out in the 60s. Scattered light rain showers will linger
over northeast washington and north idaho into the afternoon.

Drier and warmer weather is expected Monday through Thursday with
an abundance of sunshine. A cold front in the Friday and Saturday
time frame will have the potential to bring cooler and unsettled
weather to the region for the weekend.

Discussion
Today: the trough axis will move across eastern wa and north id
today. There is enough moisture in the mid levels to keep isolated
to scattered showers going across the north id panhandle an
portions of northeast wa. Winds will remain out of the west or
southwest at around 10 mph. Temperatures will feel fall like with
readings in the 60s.

Tonight through Monday night: the atmosphere will dry as a ridge
off the west coast slowly pushes towards the coast. Clouds will
decrease over the area and by Monday morning the typical cold
valleys across northern wa and id will see near freezing temps.

Daytime temps will warm 2 to 5 degrees from Sunday. Nisbet
Tuesday through Thursday: pleasant september will be in store for
the pacific northwest through Thursday. The evening model runs
continue to forecast a broad rex block over the eastern pacific.

This longwave "high over low" feature will deflect the polar jet
into northern british columbia. With the storm track north and
east of our region, afternoon temperatures across eastern
washington and north idaho will rebound into the 70s Tuesday,
Wednesday and Thursday.

Friday and Saturday: the medium range models have struggled to
handle a pattern change late in the week leading to below
average forecast confidence. The transition from the rex block in
the eastern pacific to a high amplitude split flow is causing the
models fits. The evening runs continue the trend of a weaker
northern stream cold front. Hopefully, this weaker trend has
merit. Some of the previous runs of the GFS and ECMWF hammered
central and eastern washington with strong north winds in the
fri Sat time frame... An ominously dusty scenario for a region that
has had almost no rain in recent weeks. The canadian and ecmwf
models were used as guidance with a modest push of cooler air on
Friday and the potential for rain showers for our counties along
the canadian border. The ejection of a low from the southern
stream on Saturday and Sunday has the potential to produce showers
next weekend. Again, forecast confidence is low. Models have a
heck of a time handling pattern changes especially those involving
split flow. Gkoch

Aviation
12z tafs: the trough axis is moving through eastern wa this
morning. Isolated to scattered showers will continue across NE wa
and N id. Have added a tempo -shra to ksff kcoe till 15z as
showers have developed further south than what was forecast. Given
the extensive mid level cloud deck do not think stratus will be an
issue this morning.

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.
