Short term Water vapor imagery showing well defined short wave
moving across the pacific northwest. Main impacts from this
feature will be increasing westerly winds this afternoon. Expect
most locations to be 10-25 mph with gusts to 30 mph. Clouds are
decreasing over the past few hours and will be a mostly sunny day
with highs in the 80s. Dry northwest flow aloft Sunday with sunny
skies. Continued breezy though less wind than today. Models
continue to show building upper ridge early next week with warming
temperatures followed by some tropical moisture with a slight
chance of thunderstorms late Wednesday into Thursday. 94

Aviation 18z tafs...VFR conditions are expected through the
period with just some altocumulus above 12k feet in the north this
morning and occasional few-sct cirrus. Models are also suggesting
scattered clouds at 5-7k feet at kpdt and kalw overnight. Have
included few070 for those sites but confidence is low for that
feature. Westerly winds are currently picking up this morning and
will reach 10-20 kts with gusts to 30 kts at most TAF sites this
afternoon. Kdls will reach 15-25 kts with gusts to 35 kts. Winds
will decrease this evening and will drop below 12 kts 03-07z. Perry

short term... Today through Monday night... A broad upper trough will
continue to keep a northwest flow over the forecast area through the
short term period. Today there will be a dry cold front within the
flow and an upper jet stream wind maximum which will sag southward
over the forecast area. This will cause the winds to increase until
it becomes breezy to windy... Especially on the lee of the cascade
east slopes and adjacent valleys and lower columbia basin. Wind
advisory criteria is not expected to be reached though. Relative
humidities will rise with this marine push and there will not be a
combination of wind and low humidity to create critical fire weather
conditions. However, will highlight breezy to windy conditions in
the fire weather forecast later. The winds will diminish late
tonight as the upper jet get pushed back to the northeast and the
dry cold front moves out of the area. It may become locally breezy
again on Sunday, but only in localized small areas where the winds
are normally the strongest, such as the cascade gaps, passes and the
columbia river gorge. Temperatures today will be near normal with
readings in the mid to upper 80s lower elevations and 70s mountains.

Then temperatures will cool to below normal with readings in the
lower to mid 80s lower elevations, and mainly 70s mountains on
Sunday and Monday. 88
long term... Tuesday through Saturday... The long term period begins
with strong ridging building over the west coast and troughing over
the eastern 2 3rds of the country. Very warm to hot temperatures
expected next week as the ridge axis remains overhead. Expect
afternoon highs in the 80s to mid 90s and nighttime lows in the
upper 40s to low 60s. By late week a weak wave trying to undercut
the ridge overhead, along with possible remnants of tropical storm
ivo, could bring a chance of showers and storms Wednesday night
through Thursday night, especially over the mountains in oregon.

Northerly winds 5-15 mph through next week with a thermally induced
low building south of the cwa. Ridge begins to weaken and shift east
next weekend as a stronger trough approaches the west coast. Winds
expected to increase and become more westerly with the increased
onshore flow.

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 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.
