Discussion Two words come to mind for the forecast for this
week. The first word is hot. A strong ridge develops over the
pacific northwest on Monday and remains over the area on Tuesday.
The accompaning strong thermal trof develops along the coast on
Monday and moves to the i-5 corridor on Tuesday. It then moves
just east of the cascades on Wednesday. What this means is
temperatures inland will warm significantly on Monday around 5 to
10 degrees above normal. Temperatures will warm further and peak
on Tuesday west of the cascades. Expect high 90s to 105 all along
the i-5 corridor. Roseburg will be flirting with record high
temperature territory. Temperatures should cool a few degrees west
of the cascades on Wednesday. However, temperatures east of the
cascades should peak on Wednesday with 1 to 2 degrees warmer
compared to Tuesday.
The second word is thunderstorms. Model data is showing a low
pressure trof moving toward the southern oregon coastline from the
southwest on Wednesday. With the very warm airmass over the area
and the increasing instability this low will introduce gives us
more confidence in the chance for thunderstorms Wednesday
afternoon through Thursday. This is a pattern conducive to seeing
storms west of the cascades so we have introduced a slight chance
for thunderstorms Wednesday afternoon. Depending on how this
evolves, thunderstorms could continue overnight into Thursday
morning. However, have left chances for them out for now.
Temperatures Thursday will be cooler and the short heat wave will
be over but it will still be unstable with thunderstorm chances
remaining. East of the cascades will have the best chance for
storms on Thursday.
Friday and Saturday looks to be near normal temperature-wise when
a drier southwest flow takes over as a pacific low pressure
system moves toward northwest washington. -sargeant
Aviation For the 24 18z tafs... Skies will remain clear through
this afternoon. Marine stratus will develop once again along the
coast and just offshore with MVFR ceilings to start at north bend,
lowering to ifr with local lifr ceilings late this evening and
tonight. Confidence on the timing of when lower conditions develop
are low to moderate, so watch for updates.
Onshore flow is expected to increase enough for the marine stratus
to push and or develop further inland tonight including the coquille
basin and portions of the umpqua basin. For now kept roseburg clear
through the TAF period, but there is a chance the marine stratus
could sneak in towards daybreak Sunday. Even if it does ceilings
ElsewhereVFR conditions will continue through the TAF period with
gusty winds late in the afternoon and evening hours at roseburg,
medford and klamath falls. -petrucelli
Marine Updated 205 pm pdt Saturday, 24 august 2019...
a weak thermal trough will persist along the coast today into
tonight. This will bring some gusty north winds to the southern
waters, with small craft advisory winds and seas expected south of
The thermal trough will strengthen Sunday afternoon through Monday.
This will result in strong, gusty north winds and a mix of steep to
very steep seas across the waters. Gusty winds reaching gale force
are expected for the waters south of CAPE blanco in the late
afternoon and evening on Sunday. Pockets of isolated gale force
winds could exist Monday as well. If these conditions exist Monday
evening they will be between 10 and 20 nm and south of gold beach.
Anticipate winds and seas to gradually lower on Tuesday. However, a
mix of steep to very steep seas may continue to affect the waters
Tuesday morning, with steep seas lingering across the waters Tuesday|
afternoon and evening. Expect conditions hazardous to small crafts
to persist through this time.
Fire weather Updated 200 pm pdt Saturday 24 august 2019... It will
remain dry through at least next Tuesday. There are two main short
term concerns. First will be gusty winds east of the cascades this
afternoon and evening and again Sunday afternoon and evening with
low relative humidity. Although on Sunday gusty winds should be
confined to mainly fire zone 625. Second is breezy winds with
moderate to locally poor overnight recoveries near and at the ridges
in fire zones 618, 619 and 620 Sunday night and Monday night. In
neither case are we expecting any critical fire concerns in these
areas, therefore we'll just highlight it in the fire weather
The main driving force for gusty winds east of the cascades this
afternoon and evening and again Sunday afternoon and evening will be
stronger winds aloft (at 700 and 600mb) along with an increasing
pressure gradient and it will bring speeds stronger than normal at
12 to 18 mph with gusts up to 25 mph.
Temperatures and min relative humidities this weekend will be
similar to Friday, although temperatures will end up a degree or
two lower on average for interior locations.
The hottest temperatures will be on Monday, Tuesday and Wednesday
with triple digit readings likely for interior westside valleys
Tuesday and Wednesday. The wildcard for Wednesday will be cloud
cover which could result in afternoon temperatures a few degrees
lower than what's in the forecast.
The models are coming into better agreement next Wednesday and
Thursday. The general consensus shows there is the potential for
thunderstorms Wednesday afternoon. The ECMWF and GFS show a
shortwave moving up from the south and tapping into some moisture
from tropical storm ivo during MAX heating Wednesday afternoon. So
the ingredients (trigger, moisture and instability) are present to at
least introduce a slight chance of thunderstorms Wednesday afternoon
and evening. Also the track of the shortwave is one that is
favorable for thunderstorms west of the cascades.
Another weak shortwave will be on the heals of first one Thursday,
but the track is further north and and the best chance for
thunderstorms will be north of our area. Therefore have trimmed back
the slight chance of thunderstorms and kept them confined to northern
klamath and lake county. -petrucelli

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.
