What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis for the southern oregon coastal waters..Gusty north winds and steep wind driven seas will continue south of cape blanco through tonight. Winds will strengthen and spread north to nearly all of the coastal waters late Saturday into Sunday, with gales and very steep and hazardous seas expected south of gold beach Saturday afternoon and evening. Conditions will improve slightly Sunday into Monday, but gusty north winds and steep seas will likely continue through the week.

area forecast discussion
national weather service medford or
853 pm pdt Fri jun 22 2018

Discussion No update is necessary this evening. Overall, skies
are clear this evening with the exception of some low clouds that
have formed in the last hour or so near capes arago blanco. Expect
stratus to revisit coastal locations, especially coos county
overnight and also the umpqua basin. These clouds should erode
readily Saturday morning, yielding a dry, sunny, warm afternoon.

Even the southwest coast will be warm with brookings likely
reaching into the 80s. Inland, high temperatures will be very
similar to where they ended up today - in the upper 80s to low
90s for the west side valleys and in the low to mid 80s east of
the cascades and from the shasta region eastward to modoc county.

The upper ridge will build strongly into the area Saturday night
into Sunday with model 850 temps of 24-26c at medford Sunday
afternoon. This will put some areas in the rogue illinois and
lower klamath river shasta valleys around or above 100 degrees.

The heat won't last long though since a fast-moving trough will
replace the ridge on Monday, promising cooler weather on northwest
breezes. The forecast is on track. Please see previous discussion
below for more details. -spilde

Aviation For the 23 00z tafs...VFR conditions with scattered high
level cirrus will persist through the TAF period for most of the
forecast area. The exception will be along the coast and in the
umpqua basin. Gusty winds this afternoon will diminish after sunset.

Marine layer stratus will bring the return of MVFR ifr CIGS to the
coast tonight, mainly north of CAPE blanco, including koth, and may
also return to a small section of the coastal waters south of
brookings.

Guidance is indicating the return of MVFR CIGS to the umpqua basin,
including krbg. This seems reasonable given that stratus lingered
for much of the day today and that area won't have as much daylight
hours to dry the atmosphere out. However, confidence is only
moderate since there will be offshore flow and this tends to keep
stratus out of the picture. Even so, have introduced MVFR CIGS for
krbg. Any lower conditions that develop along the coast and or in
the umpqua basin should improve toVFR by late Saturday morning with
increasing offshore flow. Br-y

Marine Updated 800 pm pdt Friday 22 june 2018... With the
intensifying thermal trough to the south, north winds are increasing
today, along with steep wind-driven seas. Most affects will be felt
south of CAPE blanco through tonight. Winds and resulting seas will
spread north to most areas by Saturday afternoon, with very steep
and hazardous seas and occasional gale force gusts expected south of
gold beach. A gale warning has been issued to account for both the
expected gale gusts and the likely hazardous sea conditions.

The thermal trough pattern will be temporarily disrupted late Sunday
into Monday as an upper level trough moves just north of the area.

Conditions, however, are likely to remain hazardous to small craft
into next week as the upper level trough will maintain tight
pressure gradients and resultant moderate to strong northerly winds.

Very steep wind driven seas look to continue into midweek with the
thermal trough strengthening Tuesday onward. Br-y bpn

Prev discussion issued 223 pm pdt Fri jun 22 2018
discussion... Sunny skies prevail over the entire forecast area,
with one exception. The umpqua basin has been a bit slower to
clear out than expected, but clouds have been burning off quick
over the last hour and expect the rest to clear by early evening.

Tonight, expect another round of low stratus along the coast,
likely reaching inland to the umpqua basin. Mild weather with
temperatures around 5 to 10 degrees above normal will continue
today across the area today. Tomorrow's weather will be will be
similar to today, though confidence is high that brookings will
see the chetco effect, bringing temperatures to at least the mid
80s, possibly near 90 tomorrow afternoon.

Outside of brookings, main story for heat will be Sunday. A
potent ridge will bring essentially a one day heat wave.

Temperatures will be in the upper 90s in west side valleys south
of the umpqua divide, and expect some locations to hit 100. East
side valleys will likely reach into the upper 80s or low 90s.

Confidence is high that Sunday will be the hottest day thus far
this year... For reference, the last time kmfr cracked 100 degrees
was sept 11. The heat will be short-lived; a cold front will
sweep through Monday, and highs will be near normal (mid 80s over
most of the cwa). The front looks to be dry, so some light
precipitation is possible along the coast, but otherwise the main
impacts of the front will be relatively cool, breezy conditions.

Expect a few days of uneventful zonal flow, then mid to late next
week, models have started projecting a trough developing, bringing
potential precipitation. -mcauley
fire weather... Warmer than normal temperatures and breezy winds
are expected east of the cascades for this evening. A thermal
trough will setup along the coast on Saturday. Winds and
temperatures will then increase along the southern oregon coast
Saturday. The thermal trough will retreat eastward on Sunday with
temperatures increasing about ten degrees across the region.

Sunday will also be the warmest day with high temperatures 15 to
possibly 20 degrees warmer than average. Daytime humidities will
fall to the mid and lower teens in valleys. Breezy and much cooler
conditions are expected Monday with a marine push in the west
side in oregon. -smith
