updated aviation discussion

Short term Tonight and Wednesday... High pressure continues over
the region but is being undercut by a low pressure system that will
eventually move into california on Thursday. Meanwhile, there will
be some increasing high level clouds over central oregon overnight
that will slowly spread northward Wednesday. Some of the moisture
associated with the low pressure will begin to move into southern
oregon Wednesday and could make its way into central oregon late in
the day or evening. Otherwise, forecast area remains warm and dry
through Wednesday.

Aviation 06z tafs...VFR conditions will prevail through the
period with some very isolated patchy fog late tonight and early
Wednesday for some possible MVFR ifr conditions which will burn off
by midday. A system over northern california will spread some mid
and high level clouds over the area late tonight and Wednesday.

Winds will generally be less than 10 kts.

short term... Tonight through Friday. Upper level ridge centered
to our northeast providing another fair weather day. Temperatures
in most locations are up a few degrees from yesterday. Satellite
shows an upper low is moving toward california. Mid and high level
clouds from this system are slowly overspreading central oregon
this afternoon. For tonight the mid and high level clouds remain
over central oregon. Mainly clear further to the north. As the low
moves into california on Wednesday expect clouds to overspread the
forecast area. Slight chance of rain along the oregon cascades.

Not much change for Thursday as the systems are slow moving due to
a blocking high in the center of the country. The low will be in
nevada with clouds spreading northward across the region. Still a
chance of light rain for central oregon and especially the
cascades with a southeasterly upslope flow. Temperatures remain
mild the next few days with highs in the 50s and freezing levels
6-9k feet. This will continue the snowmelt with many rivers and
streams running high. Another upper level trough approaching the
pacific northwest will push a cold front through the area Friday
afternoon into Fri night with rain likely. 94
long term... Friday night through Tuesday... Models continue to be in
good agreement in the overall pattern with only minor spatial and
temporal differences. An upper level trough will move across the
area Friday night and Saturday producing widespread precipitation
over oregon with lighter amounts over washington. Snow levels
are expected to be around 6000 feet but fall to near 4000-4500
feet by Saturday evening. Some lingering showers are expected
Sunday over the mountains of northeast oregon as the system slowly
exits the region. A shortwave upper level ridge is expected to move
over the region Sunday night. GFS is a little faster with the
approach of the next upper level low off the coast of oregon Monday.

Most of the energy with this system remains on the west side
of the cascades as the main low moves northward into western bc by
Tuesday afternoon. As a result, most of the precipitation will be
over our western zones, but embedded shortwaves in the southwest
flow will allow for some precipitation moving across the eastern cwa
as well, especially by Tuesday. Snow levels are expected to rise
again to around 5500-6000 feet by Tuesday. Daytime highs will
remain near to slightly above normal through the period. Earle

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.
