854 pm pdt Wed jul 17 2019

Discussion Measureable rain will be mainly north of our area,
but low and mid level clouds with a chance of showers will linger
for coos and douglas counties into early Thursday morning. This is
due to a cold front that is now reaching the coast, and will
weaken as it moves inland. Typical summer conditions will follow
for the remainder of the week with a westerly flow aloft, and
breezy to windy late day northwest to west winds at the surface.

Northeast winds on Thursday evening and again on Friday evening are
likely to result in lesser coverage and slower development of late
night coastal low clouds.

The 00z data is beginning to arrive. No significant changes are
expected through the short term portion of the forecast. The focus
as the time draws nearer will be on the development of late day
instability early next week, with a backing of the flow aloft from
westerly to southerly. The 18z data still holds off on developing a
slight risk of late day thunderstorms until Tuesday through
Thursday (day 6 through 8 of the forecast) east of the cascades.

Aviation For the 18 00z tafs... Along the coast north of cape
blanco... A mix of ifr and MVFR into Thursday morning with a chance
of light showers. The low CIGS will clear late Thursday morning with
low level northerly winds increasing for the afternoon and evening.

In the umpqua valley, conditions will deteriorate around 06z with
MVFR and a chance of light showers expected into Thursday morning.

Clouds will then diminish. Over the remainder of the area,VFR
conditions will prevail through Thursday evening.

Marine Updated 800 pm pdt Wednesday 17 july 2019... A thermal
trough along the coast will strengthen Thursday and Friday.

Conditions will become hazardous to small craft beginning
Thursday afternoon. The most hazardous conditions, including
gale force winds, will develop a few miles offshore of gold beach
and points south. Gusty north winds and choppy seas will persist
into the weekend.

Prev discussion issued 232 pm pdt Wed jul 17 2019
discussion... A weak cold front will move onshore this evening
with some light rain possible mainly on the coast from coos bay
north and across the umpqua basin. West side areas should again
awaken to ample cloud cover Thursday which will burn off quickly.

A developing strong thermal trough will produce increasing north
to northeast winds along the south coast Friday and Friday night
with offshore flow there. Near normal temperatures are on tap
through Saturday.

Sunday through Tuesday the pattern will shift into south flow over
the region under a strengthening ridge of high pressure anchored
near the 4-corners region. Temperatures will notch upward with
some west side valleys likely nearing 100 by Monday afternoon.

This pattern also brings monsoon potential, or moisture from the
south, which signals a thunder threat. We've added the mention at
this point to late Tuesday afternoon over the east, but this
period will monitored and the areal extent will probably change
over time. Stay tuned. This pattern could last through mid week
with more of the same. As the moisture arrives however, afternoon
cloud cover could play a role in how hot afternoon highs get.

Stavish
fire weather... Updated 200 pm pdt Wednesday 16 july 2019... A weak
front will bring a slight chance of showers to coos and douglas
counties tonight into Thursday. Otherwise, it will be dry with near
normal temperatures through Friday. East winds will develop over the
west side ridges Friday night, and this will make for moderate rh
recoveries over the area. This weekend will be dry with inland
temperatures warming to around five degrees above normal. Thunderstorms
are possible east of the cascades Tuesday afternoon and evening. Jrs

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.
