Short term Tonight through Wednesday... Sunny skies prevail
area wide this afternoon under dry westerly flow aloft. Channeled
w NW flow through the cascade gaps will produce breezy conditions
late this afternoon evening across the gorge kittitas valley.

Mostly clear skies will prevail through Tuesday night under the
dry west northwest flow pattern. A trough of low pressure will
approach the coast Wednesday, with a weak frontal boundary nearing
the cascade crest Wednesday afternoon. Latest model concensus
shows a little greater deep layer moisture, perhaps enough for
a few showers across the east slopes of the cascades of wa late
Wednesday. Further east, the main concern Wednesday will be the
wind. With increasing pressure gradients, expect breezy to windy
conditions for the gorge and kittitas valley, perhaps extending
as far east as the columbia basin. Will monitor for possible fire
weather impacts, but forecast wind rh conditions look to
remain under red flag criteria. Seasonably hot temperatures will
prevail for the short term, with Tuesday looking like the hottest
day, with lower elevation highs in the lower mid 90s.

Long term Wednesday night through Sunday. Wednesday night, a
weak front tries to cross the east of the cascades, but appears to
be stretched apart with little precipitation for the region. GFS is
the strongest with this feature and hold the moisture dynamics
together for a slight chance over the northeast oregon mountains.

Main effect will be some breezy winds Wednesday night. West to
northwest flow is then expected through the rest of the extended
with dry conditions and a few period of breezy winds, mainly Friday
and again Sunday. Temperatures will be around seasonal values in
the mid 80s to lower 90s.

Aviation 18z tafs...VFR conditions through the period. A few high
level cirrus clouds becoming clear overnight. Winds will be 5-15 kt
this afternoon and early evening but 15-25 kt at kdls before
diminishing overnight.

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.
