Synopsis
A drying and warming trend is expected for the inland northwest
through next week. High temperatures through the weekend will
still be below normal with highs mainly in the 60s with the
warmest spots near 70. By the end of next week, look for
temperatures to surge well into the 70s.

Discussion
Today through Sunday night: narrowing, elongating, and splitting
trof continues a slow exit to the east as it gets replaced with
northerly flow on the eastern edge of a positively tilted trof that
is slowly moving into the area. Nuisance complications of note with
this scenario necessitate low minor pops in portions of north idaho
as minor disturbances rotating counterclockwise around the outer
edges of a mesoscale low pressure circulation centered in southern
alberta have potential for producing light showers there. By tonight
the northerly flow of the positively tilted ridge has much more
influence with the earlier mentioned low pressure circulation moved
much further east and as such a dry forecast coupled with a gradual
warming trend remains in place as the ridge shows some slight
amplification but the temperatures will still be cooler than what
would be considered normal for this time of year. Pelatti
Monday through next weekend: the big story through this period will be
dry weather and warm temperatures courtesy of a a strong upper-level
ridge. The ridge will be slow to amplify Monday and Monday night
as one last shortwave passes through bringing an abundance of
clouds and chance for light mountain showers. Despite a rich fetch
of moisture tied into the system, the forcing will be on the weak
side and most locations will receive less than a tenth of an
inch. There is decent model agreement that the northern mountains
will stand the best shot at receiving a few hundredths of rainfall
while the basin receives little to nothing.

The shortwave will depart to the east Monday night then high
pressure will blossom over the northwestern us. The dry and stable
air mass will be in place through at least Friday promoting
afternoon highs in the 70s and 80s, roughly 6-10 degrees above
normal. The next disturbance will run into the ridge over the
weekend bringing a slight chance for precipitation and cooler
temperatures. There remains some uncertainty regarding
precipitation chances this far out and forecast continues to favor
a stronger ridge, little to no rain, in line with the
ecmwf canadian vs gfs. Winds are likely to be on the breezy side
as the air mass cools 4 to 5 celsius from Friday to Sunday. For
the first week of autumn, the weather looks to start off rather
quiet with no hazardous weather anticipated. Sb

06z tafs: a deck of mid level clouds with CIGS above 6 kft agl
will linger over the region. There is a slight chance that this
moisture will result in light rain across the northern panhandle
late tonight into Saturday morning. Isolated afternoon showers
will then be possible over extreme eastern wa and the id panhandle
for Saturday afternoon. Mountain obscurations will be possible
over the id panhandle. Svh

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.
