Short term Today through Thursday... A short wave and associated
cold front are moving over vancouver island this afternoon. Models
show that the mid levels in the atmosphere will remain very dry
with this system so the main effects will be winds and much colder
temperatures. Water vapor satellite shows a strong dry slot that
indicates strong winds in the jet. These winds will mix down to
the surface after the front moves through wa and or tonight. Tight
surface pressure gradients and higher winds aloft mixing to the
surface will increase the northwesterly winds tonight and
Wednesday over the lower columbia basin and adjacent areas. A wind
advisory has been issued for the kittitas valley starting at
midnight.

The upper level trough will remain over the area Wednesday with
much colder temperatures. Afternoon high temperatures today
reached the mid 80s to mid 90s. By tomorrow high temperatures will
be 15-20 degrees colder when colder air moves into eastern wa and
or behind the front. The trickiest part of the forecast will be
low temperatures tonight. Winds will be strong enough to inhibit
nighttime cooling especially in the columbia basin.

A pair of short waves moving through the upper trough Wednesday
night and Thursday morning will increase the moisture and
instability over eastern wa and or. By Thursday morning skies will
be partly to mostly cloudy skies and some showers will develop.

Weak instability and steep lapse rates may trigger a few
thunderstorms Thursday afternoon evening, mainly over the wa
cascades and northeast oregon mountains. Winds will be lighter.

Friday an upper level ridge will build again offshore. Subsidence
from the ridge will start to dry out central and eastern wa and or
but enough moisture and instability may linger over far eastern or
to trigger a few showers and thunderstorms in the afternoon.

Coonfield

Long term Friday night through Tuesday... A ridge of high pressure
will build in from the west late Friday and remain over the region
through the extended period. This will place temperatures at above
normal and winds generally light. Main weather concern will be the
possibility of thunderstorms developing on Monday and Tuesday mainly
over the mountains areas.

Aviation 00z tafs...VFR conditions will prevail over the next
24 hour. Skies will just have a few cirrus clouds and perhaps some
cumulus over the mountains. A dry cold front will move into the area
this evening increasing becoming windy over the next 24 hours with
15-30 kts winds and higher gusts.

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.
