Area Forecast Discussion
National Weather Service Medford OR
916 PM PDT Wed Mar 24 2021

.UPDATE...

Forecast remains on track tonight with low topped showers spread across
southern Oregon and northern California this evening. We're
expecting these showers to persist along the Cascades through the
night producing 1 to 3 inches of snow above 3000 feet. Otherwise,
conditions are still expected to dry and warm into Thursday.

-Smith

&&

.SHORT TERM.../Issued 253 PM PDT Wed Mar 24 2021/

The main line of showers has moved onshore and is banking up
along the Cascades. So far most accumulations have been light,
measuring less than a tenth in the CWA, and 0.11" at Goodwin Peak
RAWS which is just inside Lane County north of Scottsburg.

Winds along this line of showers has been well forecast so far.
Peak gusts have remained in the mid-teens across area peaks and
ridges. As the front moves over the Cascades, expect winds to pick
up there, and east of the Cascades as well. The strongest winds
will struggle to materialize at the surface, except in the
Christmas Valley area, where winds could become breezy.

Snow levels this afternoon start out between 4500 and 5000 feet,
lowering to just below 3000 feet Thursday morning. However due to
a stronger mid March sun, road temperatures should be warm enough
to prevent snow from sticking on the roads near and at Siskiyou
Summit. The exception will be on elevated roads, such is bridges
and overpasses where slick spots are possible. Higher passes along
the Cascades have a better chance of snow covered roads by
daybreak Thursday, but were only talking about 2-5 inches around
Diamond Lake, Crater Lake and Lake of the Woods. Any road snow in
these areas will quickly melt off, especially in sun exposed areas
mid to late Thursday morning.

The weather on Thursday will be similar to what we experienced
Monday. Post frontal showers are expected mainly along and west of
the Cascades with most showers centered along the Cascades. Even
then, showers are expected to gradually diminish in the
afternoon. A northwest wind will keep the eastside breezy,
especially in the afternoon. However, winds will remain below
advisory criteria.

As higher pressure begins to build back into the region Thursday
evening into Friday morning, cloud cover will begin to dissipate.
Under a relatively cool airmass, the clearing skies will allow
for additional cooling. This continues a low chance for frost
along the coastal areas of the Coos coast. Have introduced patchy
frost wording to the the forecast, but it is important to note
that we are using a colder solution and the likelihood of
occurrence near 10%. This also coincides with conditions
conducive to patchy fog in the Umpqua Basin. -Miles

.LONG TERM.../Issued 253 PM PDT Wed Mar 24 2021/
(Saturday through Wednesday)...A spring pattern will be in place
this weekend into next week. Initially an upper level ridge will
bring warm and dry conditions. This is followed by cooler
conditions and chances for precipitation as a front and upper
trough move into the region Sunday evening through Monday. Then
expect drier and warmer conditions Tuesday and Wednesday as the
upper ridge builds back in place.

On Saturday as the upper level ridge remain over the region
Saturday, expect light winds, clear skies and very warm temperatures
inland. Models continue to show highs around 8 to 15 degrees above
normal across inland areas. Saturday high temperatures are forecast
in the upper 60s to 70s for inland valleys west of the Cascades and
in the mid to upper 60s for valleys east of the Cascades. Along the
coast, highs are expected in the mid to upper 60s.

The upper ridge will begin to break down Sunday as a front
approaches. During the day Sunday, expect warm temperatures to
continue but trend slightly lower compared to Saturday. Models have
come into better agreement with the front and upper trough moving
into the area Sunday evening through Monday morning. This front will
bring light precipitation to the area. The GEFS has continued to
trend wetter and is in line with the ECMWF ensemble forecast. This
is reflected in the NBM forecast as well. We have increased the
chance for precipitation over the area, Sunday evening into Monday
morning, with best chances from the Cascades west. Models do
indicate a chance for precipitation to spread east of the Cascades
Sunday night and Monday. With the passage of the front, snow levels
are expected to lower from 5000 to 6000+ feet Sunday evening down to
2000 to 4000 feet Sunday night then down to around 1500 to 2500 feet
Monday morning in showers.

Models continue to indicate that the upper trough will shift
eastward and the upper ridge will build back into the region late
Monday into Tuesday. Weaker disturbances embedded in this trough may
bring continued chances for showers, especially from the Cascades
west, Monday afternoon and Monday night. Then as the upper level
ridge builds into the area late Tuesday and Wednesday , expect a
shift to drier north to northeast flow, with warmer temperatures,
and gusty winds over the coastal waters, coast and coastal
mountains. -CC

&&

.AVIATION...For the 25/00Z TAF Cycle...VFR conditions prevail across
much of the area ahead of a front currently pushing onshore. The
front is bringing lower conditions at the coast, where IFR
conditions are occurring. Tonight into Thursday, terrain
obscurations will continue across the region, and conditions are
expected to lower to MVFR across the west side as the front moves
inland. The front will weaken as it moves inland, and VFR is
expected to prevail east of the Cascades. Conditions improve by late
Thursday morning, but terrain obscurations will continue, especially
west of the Cascades as showers continue into the afternoon. /BR-y

&&

.MARINE...Updated 800 PM PDT Wednesday 24 Mar 2021...Gusty
northwest to north winds and steep seas will persist through
Thursday night, with seas expected to peak at 12-13 feet Thursday
morning and afternoon. Offshore high pressure and a thermal trough
near the coast will return Friday, then weaken Sunday. This will
likely produce another episode of gusty north winds (strongest south
of Cape Blanco) into Saturday night. Another front will move onshore
Sunday evening. -Spilde/BR-y
