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 through Tuesday.

Discussion
Tonight through Saturday: a high pressure ridge will build in over
the next 48 hours. Strong subsidence and dry air will suppress
cloud cover with clear and sunny skies. Temperatures will see a
warming trend to above normal with widespread 80s Friday and mid
80s to low 90s by Saturday. Svh
Saturday night through Monday: the upper level ridge axis shifts
east into eastern wa which will keep temperatures rising. Sunday
valley temps will heat up to upper 80s to mid 90s, with a few
degrees of additional warming on Monday. Monday will be the
warmest day in the 7 day forecast. These daytime temps are 14-18
degrees above average and overnight lows 5 to 12 degrees above
average for this time of the year. Mostly clear skies are expected
with some cirrus streaming in Sunday and Monday. Monday afternoon
southwesterly winds start to pick up across the east slope into
the columbia basin as the ridge gets pushed east.

Monday evening and Tuesday: lots happening these periods. The
first is the models showing some energy moving up from the
southwest Monday evening into Tuesday morning. Models have a very
difficult time nailing down the specific track of these waves, but
it looks to mainly impact southeast wa and the southern id
panhandle. The gfs-that shows the strongest waves-has quite a bit
of convective inhibition which would make it difficult for
thunderstorms to get going. However given the pattern recognition
have added thunder across extreme southeast wa and the southern id
panhandle with the hopes of honning in on it better as the event
approaches and the models can see better detail of timing and
track.

The second weather feature to watch is a low pressure system
moving into canada from the gulf of alaska. There are some pretty
big model differences and the confidence in this portion of the
forecast is quite low. The GFS has been consistent in digging that
low down into our area on Tuesday while the ECMWF has been
consistent with itself in keeping the low in northern bc and
alberta. Of course the models are consistent with themselves but
totally different from each other! The canadian seems to track the
low right in the middle of the other two models. The canadian as
well as the ec keep the forecast dry. Wasn't confident to take out
our slight chance showers across NE wa and north id along the
canadian border, but didn't increase our chance of precipitation.

With the breakdown of the ridge and the low pressure moving
somewhere to the north of wa, our winds will increase. Winds will
pick up Monday evening and continue through the night and into
Tuesday evening. They look to peak Tuesday late afternoon and
early evening. The main area of concern is from the central east
slopes of the cascades east into the columbia basin and into the
palouse and spokane area. The winds Monday will be a concern as rh
values will be in the upper teens to near 20 percent. This will
bring fire weather concerns to the columbia basin. Tuesday the
winds will be slightly stronger, but temperatures should drop
about 10 degrees and rh values should come up a bit.

Wednesday and Thursday: models are having trouble with what to do
with the ridge to the west and whether or not to bring a cut off
low into the region. Temperatures will remain at or above average
for this time of the year. Low confidence on our chance of precip
across extreme NE wa and north id. Nisbet

Aviation
00z tafs: dry northwest flow will bringVFR conditions to the taf
sites through the period. Locally gusty westerly winds will taper
off early near kpuw & klws with light north east winds overnight.

Light winds will continue into Friday with speeds under 10kts.

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.
