Short term Morning update... The upper level ridge continues over
the pacific northwest this morning, but has shifted east enough that
the ridge axis is over eastern washington and oregon. This ridge
will largely remain in it's current location through today, then
begin to slowly shift east tonight as a weak pacific system
approaches the region. As such, the eastern two-thirds of the
interior northwest will remain under light north or variable flow,
with a fairly dry air mass in place. Thus expect only a few
afternoon evening cumulus clouds over the mountains with little to
no chance of precip. As for central oregon north to south-central
washington, the flow will be southerly with increasing moisture and
instability. Thus will see some showers and thunderstorms develop
late this afternoon and evening. High temps will continue to be well
above seasonal. Made updates of shower storm chances and locations
for this afternoon and tonight. Also made some adjustments to high
temps, sky cover and winds through tonight. 90

Long term Previous discussion... A broad mid upper level trough in
the gulf of alaska sets the stage for a cyclonic flow aloft over the
forecast area Wednesday night, which will allow a SW flow to
continue over the eastern oregon mountains for a chance of showers
Wednesday night along with a slight chance of evening thunderstorms
in the blue mountains with threat of thunderstorms ending by sunset.

Thursday a mid upper level shortwave in the upstream westerly flow
makes landfall and sweeps across interior pacific northwest during
the day on Thursday, thus keeping a chance of orographic showers
over the eastern oregon mountains with a slight chance of
thunderstorms in the blue mountains during the afternoon evening.

Thursday night the shortwave exits into idaho in the evening
resulting in showers tapering off and ending in the evening. Friday
through the weekend flat high pressure will keep dry conditions in
the region.

Aviation Previous discussion... 12z tafs... Clear skies tonight
into Monday morning. Sct cumulus 060-090 developing in the afternoon
mainly over the mountains. Winds 5-10kt.

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.
