Short term Short wave moving through in the northerly flow
aloft combined with a cold front resulting in scattered snow
showers and cloudy skies. Expect this will continue overnight.

Northerly flow continues Monday although the airmass is drying so
partly to mostly cloudy skies. The next system to impact the
region will be a low moving across the pacific northwest Tuesday
into Wednesday. This will result in another round of accumulating
snowfall. Model precipitation forecasts show a significant amount
for the mountains. Temperatures will remain well below normal
through the period. 94

short term... Tonight through Wednesday... A large trough remains
over most of the CONUS this afternoon. An upper low is moving
south over northern california and nevada and its influence over
our area is steadily decreasing. Another low pressure area in
southern alberta is sending a cold northerly flow into the area.

Moisture is limited with the incoming arctic air but radar is
showing some returns over the columbia basin and blue mountain
foothills. Am expecting isolated light snow showers mainly over
the washington cascades, blue mountain foothills and northeast
oregon mountains but anywhere aside from the washington columbia
basin and central oregon could see a stray shower. Snow amounts
will be less than an inch. Snow showers will taper off tomorrow
morning and the area will get a break Monday afternoon through
Tuesday morning. The main story will be colder temperatures as
lows tonight will be in the teens and in the mid single digits to
mid teens Monday night. Tomorrow will have high temperatures
mainly in the 20s though central oregon should reach the lower
30s. The next concern will be a system out of the gulf of alaska
arriving Tuesday afternoon and impacting the area through
Wednesday. The entire area will have snow with this system and
winter weather highlights appear probable Tuesday night and
Wednesday over the blue mountain foothills, grande ronde valley
and wallowa county (2-5 inches) and eastern oregon mountains (4-9
inches). The rest of the area will get 1-3 inches. Future shifts
will have to monitor to see when the confidence is there for any
watches, advisories and warnings to be issued. With increased
cloud cover, lows Tuesday night will be in the 20s and highs
Wednesday will be in the mid 20s to mid 30s. Perry
long term... Wednesday night through Sunday. Snow showers will
linger over the area Wednesday night as the upper level system
starts to move east. It will continue to be cold through the week,
but should be drier Thursday into Friday as a ridge of high pressure
moves through. Another low pressure system will be approaching the
area Friday night with a chance of light snow across the area
Saturday with a cold front Saturday night. The upper level trough
remains over the area Sunday with another low dropping down the
coast. This will turn the flow more zonal and keep some area just
east of the cascades more shadowed from light snow but most area
will continue to see some periods of light snow. Temperatures will
remain below normal. 93
aviation... 00z tafs. Ifr lifr low clouds and fog will continue
through the evening at pdt alw psc as band of low clouds continue
to move south over the area and bank up against the blue
mountains. Ykm will also see slight upslope flow with light snow
and MVFR conditions overnight. Northerly flow will continue on
Monday with some clouds banked along the foothills with MVFR at
alw pdt and mainlyVFR at other locations. 93

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.
