Update A strong and dry high pressure system will continue to
build across the pacnw tonight. Mainly clear skies will allow for
radiational cooling and forecast low temps were decreased a
degree to two. Otherwise a warming trend is expected this weekend
and the present short term forecast appears on track.

Aviation Vfr conditions can be expected across all TAF sites for
the next 24 hours.

Prev discussion issued 148 pm pdt Fri jun 23 2017
short term... Tonight through Monday... Ridge of high pressure off
the coast will continue to move inland and exert its self upon the
region over the weekend. Temperatures will increase each day peaking
on Sunday with highs around 100 degrees in the lower columbia basin.

Meanwhile, a small upper level low pressure system off the coast of
california will begin to lift some moisture northward which will
creep into southern oregon on Sunday. This will lead to a slight
chance of thunderstorms which could reach into central oregon by
Sunday evening. On Monday the ridge will shift eastward and the
remnants of the low pressure will move across the forecast area.

This will lead to a chance of thunderstorms Monday afternoon and
evening from central oregon, across eastern oregon mountains and
into southeast washington. Will also see increasing westerly winds
Monday afternoon as a marine push gets underway. This will bring
some cooler air into the western portion of the forecast area but
expected continued hot over the eastern portion.

Long term... Late Monday night through Friday... Upper level
troughing will exit the area to the east by early Tuesday.

Precip coverage will diminish late Monday night, with some residual
showers across the eastern mountains. Surface pressure gradients
will tighten Tuesday, producing breezy to windy conditions for the
columbia basin and gorge, as well as the kittitas valley. A weak
wave or two will cross the area Tuesday into Wednesday in zonal
flow, but with little deep moisture to work with, expect no
precipitation. Upper level ridging will rebuild just offshore wa or
for late week resulting in dry conditions area wide. Temperatures
within a couple degrees of normal Tuesday Wednesday will warm to 5-7
degrees above normal for Thursday Friday.

Fire weather... Hot and dry conditions this weekend will be
followed by active thunderstorms in central and northeast oregon
and southeast washington on Monday. Talking with neighboring land
management agencies, the fine fuels such as grasses and shrubs in
central and southeast oregon have cured or almost cured.

Therefore, any new lightning starts could result in rapid fire
spread. Fire weather watches will be issued for Monday in fire
weather zones 640 and 644 which covers the prineville district,
odf john day, and heppner district. Thunderstorms in the blue
mountains and wallowa county will also produce abundant lightning,
but the fuels are still green or showing signs of curing. Winds
will also increase in the eastern columbia river gorge and the
lower columbia basin on Monday and will become windy in some
areas, but the humidities will also increase to around 18-28
percent. At this time, I will hold off on any watches but
forecasters will monitor closely for changes that may warrant
highlights. Wister

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.
