What forecasters said that day

The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Medford, OR wrote its last area forecast discussion before this small craft advisory went out at May 17, 10:40 PM PDT, 2 hours 43 minutes earlier.

Area forecast discussion, May 17, 10:40 PM PDT, 2 hours 43 minutes before
Area Forecast Discussion
National Weather Service Medford OR
1040 PM PDT Mon May 17 2021

.Updated Aviation Discussion.

.AVIATION...For the 18/06Z TAF Cycle...Near the coast and just
offshore...Onshore flow behind the front is expected to result in
marine stratus reforming later this evening and tonight. Confidence
is not high ceilings will lower much beyond MVFR, but it will be
close. VFR ceilings are expected to return tomorrow morning until
the end of the TAF period at the coast, but could remain MVFR
offshore.

Inland west of the Cascades, VFR ceilings are expected to start.
Between 10 and 12z, a mix of MVFR and VFR ceilings is expected in
the Umpqua Valley, including Roseburg with partial mountain
obscurations. Clouds will spill over the Umpqua Divide into the
Rogue Valley between 09-11z with a chance for the higher terrain to
become partly obscured, but VFR ceilings will continue at Medford.
MVFR ceilings in the Umpqua Basin should improve to VFR late
tomorrow morning (between 17-19z).

VFR conditions will continue through the TAF period east of the
Cascades.

Gusty winds are likely again tomorrow afternoon, but they are not
expected to be as strong as they were MOnday afternoon and evening.
-Petrucelli

&&

.DISCUSSION...Satellite imagery shows a band of high clouds
moving across southern Oregon and portions of northern California
ahead of the weak front moving through the area. Below the high
clouds, a marine stratus layer exists offshore and along the coast
and even into the Coquille valley. Overall, not expecting any
impacts with this system, but winds will remain breezy during the
day tomorrow ahead of the next front arriving on Wednesday
bringing a larger cooling trend. Overall, this seems well-
forecast, and no changes are need in this update. For more
information about the forecast, please read the previous
discussion below. -Schaaf

&&

.MARINE...Updated 840 PM PDT Monday, 17 May 2021...A cold front has
moved onshore with light to moderate west to southwest winds.
Offshore high pressure sets up tonight into Tuesday. An upper trough
will drop south over the waters bringing moderate north winds that
should remain below small craft Wednesday. Northwest swell will
increase tonight into Tuesday, but they are only expected to be
between 5 and 6 feet and should remain in that range through the end
of the week.

The combination of moderate north winds behind a cold front and west
to northwest swell could result in smaller craft conditions
Wednesday night into Thursday. _Petrucelli

.PREV DISCUSSION... /Issued 501 PM PDT Mon May 17 2021/

DISCUSSION...17/12Z NAM/GFS/EC in.

Lots of low clouds and fog over the coastal waters, along the
coast, and in the coastal valleys this afternoon. There are
some stratocumulus clouds in the lee of Mount Shasta, and some
are popping over ridges as well. Clear skies prevail over the
remainder of the Medford forecast area.

The upper level ridge over the area has broken down in advance of
an incoming long wave trough. Short waves ejecting from the trough
will support two landfalling fronts, one tonight, and the other
Wednesday. Both of these fronts will only have light precipitation
associated with them, most of which will fall over the coastal
waters, along the coast, and in the Umpqua Basin. The bigger
impacts will be temperatures and winds.

Today will be the first day of a strong cooling trend that will
continue through Wednesday. By that time, highs over the inland
areas will be 20-30 degrees cooler than the highs yesterday, and
will be around 5-10 degrees below normal.

As for winds, it now looks like southwest to northwest winds will
be gusty in the afternoons and evenings through Wednesday both
west and east of the Cascades.

The upper trough will dig into the Pacific Northwest Wednesday
night, and once it gets here it will set up shop for a while,
moving very slowly east. Looking at the large scale pattern, it
looks like a weak double omega block across the western hemisphere
with anchor lows over the Aleutians, Pacific Northwest, and off
the US east coast, with highs in between. It doesn't quite get to
the classic blocking configuration though.

This will bring a mix of light rain and snow showers east of the
Cascades and the ridges west of the Cascades with snow levels
around 3500 feet Wednesday morning. However, the recent warm
temperatures have left a lot of residual heat in the ground, and
any snow that falls will melt very quickly and no impacts on
travel are expected.

The trough will remain in the area Thursday through Saturday,
making for a showery regime over the area. It will also be windy
east of the Cascades, with northerly prevailing winds. A slow
warming trend will occur as the trough drifts east.  At this
time, it looks like the trough will move out Sunday, and the area
will dry out and continue to warm Sunday into Monday.

MARINE...Updated 200 PM PDT Monday, 17 May 2021...Seas will
remain low tonight under a broad area of high pressure. Eventually,
seas will begin to increase Tuesday as a higher swell moves in.
These elevated seas will persist through Wednesday until the
northerly winds begin to increase Wednesday evening along a cold
front. Conditions may be hazardous to smaller crafts Wednesday night
into Thursday as this front moves through the waters.  Higher
elevated seas will persist into the weekend.
