Synopsis A strong upper level ridge with low level offshore
flow will result in one more sunny day Wednesday - with likely
record high temperatures. Lower upper level heights and weakening
low level offshore flow will keep conditions a bit cooler - but
still dry on Thursday. A front will spread light rain northeast
across the area on Friday. There will be a chance of showers next
weekend with near normal temperatures.

Short term tonight through Friday Gusty easterly winds tonight
will ease, with clear skies. Wednesday will be another warm day over

southerly surge will develop over the oregon coast - bringing late
night and morning stratus to the coast and portions of the interior
by Thursday morning. Low temperatures will drop into the 40s, with
highs on Thursday reaching into the mid 60s through the interior -
well above normal. High temperatures along the coast will remain
near normal on the coast, in the mid 50s. Southerly flow aloft may
allow isolated showers over southern sections in the afternoon and
evening.

On Friday a weakening trough will move inland helping to spread
light rain onto the coast in the afternoon and inland Thursday
evening.

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.
