Temperatures will be much above average through Monday, with
afternoon temperatures well into the 90s. The arrival of a cold
front Monday evening will bring the potential for widely
scattered showers and thunderstorms to the idaho panhandle and
eastern washington. Some thunderstorms may produce gusty winds
Monday afternoon and evening. Winds will be breezy Tuesday and
Wednesday as temperatures fall back into the 80s.

Thunderstorms with gusty winds possible late Monday afternoon
and evening...

tonight through Tuesday: the upper level ridge will shift east
this afternoon and open up the pac NW to a southwest flow. For
tonight expect light winds and temperatures about 10-15 degrees
above average (upper 50s and 60s). Moisture currently seen along
the ca or border will move north overnight and provide an increase
in high level clouds.

Monday eastern wa and north id will be right in between two
systems moving across the western us. The first is a cutoff low
that moves across british columbia. The second is a weather
disturbance that is moving into northern ca and southern or.

Sprinkles will be possible during the morning hours. By mid to
late afternoon our chance of showers and thunderstorms will
increase as our instability and moisture increases. Temperatures
similar to Sunday can be expected (upper 80s to 90s). High
resolution models are showing the precipitation moving in a bit
further to the west than was previously forecasted. Have extended
the threat of thunder as far west as republic and moses lake. Have
also increased our chance across the spokane coe area as well as
the palouse. The main impact with these storms will be gusty winds
and lightning. The threat of storms will continue through the
evening hours before pushing into north id and western mt
overnight. Westerly winds will remain breezy through the evening
and overnight hours across the cascade gaps and into the columbia
basin. Tuesday will be much quieter, with a cool down of about 10
degrees from Monday. Nisbet
´╗┐Tuesday night through Thursday: expect limited shower chances
and temperatures closer to seasonal averages. Low pressure
currently in the gulf of ak moves to alberta by the start of this
period before heading toward the north-central plains.

Disturbances round its backside pivot by the inland NW in the
west northwest flow. These, plus some orographic enhancement, will
lead to the occasional threat of showers and afternoon
thunderstorms. The threat will be highest around the north and
eastern mountains in the afternoon early evening hours. Within
this period the best risk will be around Wednesday. It is possible
some showers may also slip off the mountains into the
northeastern columbia basin, around the spokane c'da area and
palouse. Yet confidence in this occurrence is low. Winds will be
occasionally breezy in the afternoon evening hours focused
especially around Tuesday and Wednesday.

Friday through Sunday: the inland NW transitions to a slightly
more active westerly flow, with somewhat better shower chances.

Friday morning a shortwave ridge leads in the next in pacific
shortwave trough which enter late Friday afternoon into Friday
night, with a second following it up later Saturday into Sunday.

These will provide broader shower chances throughout the mountain
zones, as well as limited shower chances across the northeastern
columbia basin. At this time precipitation outside of the
mountains looks more isolated in nature. The zonal westerly flow
temperatures will remain near seasonal averages. J. Cote'

06z tafs: changes expected during the next 24 hours. High
pressure will weaken Monday and shift to the east. Thin cirrus
will stream across the aviation area through the night. Monday the
flow will be more from the southwest and there is a hint that
some elevated forced early morning convection in the form of light
showers or sprinkles will pass through portions of eastern
washington and north idaho between 12z-18z Monday. Near and beyond
23z Monday surface based convection, some in the form of isolated
thunderstorms producing gusty wind, is expected to form and pass
through eastern washington and north idaho. Storm motion looks to
be from southwest to northeast at 20 to 25 mph. Pelatti

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
