updated aviation discussion

Short term Tonight through Friday... An upper level ridge of high
pressure will build and intensify over the next couple of days off
the coast before moving inland Thursday. This will place the
forecast area under a dry northwest flow through Wednesday. Then the
ridge will pass over the region Thursday and into Friday before the
next cold front is expected late Friday but with limited
precipitation. Breezy winds this evening will decrease and become
light until the next cold front on Friday.

Long term Friday night through Tuesday... Friday night and
Saturday a cold front and trough will cross the area. Most of the
energy will be north of us but it will bring a chance of light
showers along the cascades Friday night and over northeast oregon
Friday night and Saturday. The main impacts will be breezy 15 to 25
mph winds Friday night and much colder air arriving behind the front
on Saturday. Temperatures Saturday will be 10 to 15 degrees cooler
than on Friday with 50s in the lower elevations and in the 40s in
the mountains. Snow levels will drop from 8000-9000 feet Friday
evening to 3500-4500 feet by Saturday afternoon. Since precipitation
will be very limited on Saturday, do not expect any significant snow
fall. The trough will leave the area Saturday night and a dry
northerly flow will be over the area Sunday through Monday. This
should be a quiet period with no precipitation. However temperatures
will be even cooler with highs in the upper 40s and lower 50s in the
lower elevations and in the upper 30s and 40s in the mountains. Lows
will be in the mid 20s to lower 30s with mid teens to mid 20s in the
mountains. Models diverge Monday night and Tuesday with the gfs
bringing an offshore ridge over the area while the ECMWF brings a
low and backdoor cold front out of saskatchewan to brush the eastern
portion of the area. Both scenarios would keep us dry. However, the
gfs would warm us up a few degrees and the ECMWF would drop our
temperatures a few more degrees. Leaned towards the cooler ECMWF as
it had more support from the canadian model and the nbm. So Tuesday
would be in the mid to upper 40s in the lower elevations and in the
mid 30s to mid 40s in the mountains. Perry

Aviation 00z tafs...VFR conditions will prevail through the next
24 hours. Sct-bkn high level cirrus will be decreasing late tonight
as northwest flow remains over the area. Winds will be decreasing
this evening and will remain generally under 10kt through the rest
of the period. 93

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.
