200 am pst Wed dec 13 2017

Discussion 13 00z nam GFS ec in.

A strong upper level ridge continues to dominate the weather
pattern over the west coast states. Over the medford cwa, this has
resulted in very dry conditions with warm temperatures and breezy
winds over the ridges. Over the west side valleys, inversions are
making for cooler conditions with little or no winds, along with
areas of low clouds and fog freezing fog.

The ridge will weaken Friday as a short wave moves over the top of
it. This will push a weak front onshore at that time. Given the
persistence of the ridge event, it will be moving into a very dry
air mass and there will be little or no precipitation associated
with it. Amounts will be less than 0.05 inches and the bulk of the
precipitation will be limited to the coast and umpqua basin.

However, a few renegade showers may develop elsewhere along the
front. There may be enough cooling aloft to break the valley
inversion so there may be some decent mixing in the valleys
Friday.

However, that break won't last long. The ridge will return this
weekend as a rex block sets up offshore. This will bring a return
of the conditions that are currently over the area. The 13 00z ec
shows a weak front moving onshore next Tuesday and Tuesday night
but the 13 00z GFS remains dry. The models, especially the ec,
have been inconsistent with this feature, so will not change the
current forecast for Tuesday.

Aviation 13 06z TAF cycle... Fog and freezing fog will return
to the same areas this evening and persist into Wednesday morning.

Vfr conditions will prevail elsewhere, including the east side,
coast, and coastal waters. Dense freezing fog and very low stratus
will return to the medford area late tonight. Breaking out toVFR
again mid to late morning. Sven

Marine Updated 200 am pst Wednesday 13 dec 2017... Relatively
light winds for this time of year will persist through the rest of
the week. North winds will persist and will be strongest south of
cape blanco, but they are expected to remain below small craft
advisory level. Moderate west swell will build this afternoon
through Thursday and subside Friday, but seas should remain below 10
feet. A weak front will move onshore Friday, followed by offshore
high pressure Saturday. North winds will increase Saturday and could
be strong enough to reach small craft advisory levels in the
southern waters. -sven sk

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.
