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 27, 8:03 PM PDT, 1 hour 43 minutes earlier.

Area forecast discussion, May 27, 8:03 PM PDT, 1 hour 43 minutes before
Area Forecast Discussion
National Weather Service Medford OR
803 PM PDT Thu May 27 2021

.DISCUSSION...28/00Z NAM in.

An upper level trough over the Pacific Northwest will move out to
the east later tonight. As it does so any precipitation associated
with the surface front will diminish, ending by sunrise Friday.
Not that there is much going on now in that department.

A strong upper level ridge will then build into the area. A
thermal trough will deepen along the coast with easterly winds
developing over the Coast Range ridges by Friday morning. The
ridge will continue to build and remain over the region into next
week. Ensemble meteograms are all in agreement with zero
precipitation and increasing temperatures Friday through Tuesday.
Inland high temperatures Tuesday are forecast to be around 20
degrees above normal values, and Medford is currently forecast to
top 100 degrees that day.

The ridge will shift to the east of the area Tuesday night, but
heights will remain high over the area as the incoming trough will
be weak. The return of onshore flow Wednesday will cool temperatures
down a bit on the west side. East side high temperatures will be
similar to the Tuesday highs.

Southerly flow ahead of a weak trough will allow moisture into
the region. This, combined with instability induced by strong
surface heating, brings the possibility of thunderstorms back
into the forecast beginning Wednesday afternoon and evening and
again Thursday afternoon and evening. The best chances will be
east of the Cascades, but confidence in the occurrence and
location of any thunderstorm activity is low at this time.

&&

.AVIATION...For the 28/00Z TAF Cycle...Gusty westerly winds
will continue east of the Cascades this evening. Patchy MVFR
ceilings and visibilities are expected to return late this evening
into early Friday morning along the coast north of Cape Blanco, and
into the Coquille Valley near North Bend. Otherwise and elsewhere,
conditions will be VFR. -DW

&&

.MARINE...Updated 800 PM PDT Thursday 27 May 2021...Seas
tonight will remain dominated by a fresh west-northwest swell.
Strong north winds will then develop as a thermal trough builds
along the coast. Wind waves become very steep south of Port Orford
Friday afternoon and evening, and steep north of Port Orford as seas
build to a peak of 8 to 12 feet.

Winds will not be quite as strong Saturday, but the thermal trough
will deepen again with winds in the southern waters trending higher
again Sunday and Monday. This pattern is likely to persist through
mid-week with strong north winds, possible gales, and steep to very
steep seas, especially south of Cape Blanco. -DW

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF northern
California...south central Oregon AND southwest Oregon.

.Day One...Tonight

No hazardous weather is expected at this time.

.Days Two through Seven...Friday through Wednesday

Building high pressure will result in a steady warming trend
through the weekend, culminating in the regions first heat wave of
the season early next week. Triple digit high temperatures are
expected for the valleys of Josephine, Jackson, and Siskiyou
Counties Tuesday and Wednesday. This near-record heat could pose
an increased risk to those sensitive to heat, or those outdoors
for extended periods of time. Area rivers and streams may seem a
safe refuge from the heat, but cold water temperatures themselves
could pose an increased risk for shock and drowning.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.
