Area Forecast Discussion
National Weather Service Medford OR
246 PM PDT Tue May 28 2019
The Long Term section has been updated...
.SHORT TERM...As a broad upper trough remains over the western
U.S. and an upper level shortwave will gradually move down from
the north into the area this evening into Wednesday. The shortwave
is forecast to develop into a weak closed low over the area late
Wednesday and remain over the area on Thursday before gradually
shifting south on Friday. This pattern will bring showers and
thunderstorms each afternoon and evening through late this week.
The best chance for showers and thunderstorms will be from the
Cascades east. However, as the low moves over the area late
Wednesday and Thursday, showers and thunderstorms are also
possible in some western areas such as southwest and south-
central Siskiyou County and into the Siskiyou mountains.
Otherwise, expect a gradual warming trend today through Friday for
inland areas. Coastal areas will see some overnight and morning
low clouds with breezy to gusty north winds in the afternoons and
evenings through Friday.
This afternoon, scattered showers have developed from the
Cascades east and isolated thunderstorms have developed in
northern Lake and Klamath counties. Models show increasing
instability and chances for showers and thunderstorms through the
afternoon and into the evening today for areas from the Cascades
east. For areas west of the Cascades, given that models show good
agreement with more stable conditions and less mid level
moisture, have kept showers and thunderstorms out of the forecast.
With the shortwave developing into a weak low and remaining
positioned over southern Oregon Wednesday afternoon into
Thursday, expect increasing chances for showers and thunderstorms
from the Cascades east and over portions of western and central
Siskiyou county as well as into the Siskiyou Mountains. Models
continue to show more stable conditions west of the Cascades in
southwest Oregon. So have kept dry weather in place Wednesday and
Thursday for western zones. Additionally, marine low clouds are
expected for portions of the coast, mainly from Cape Blanco north,
and into the Umpqua as well as portions of the Rogue, Applegate
and Illinois valleys in the overnight and morning hours.
Friday, the low will shift south-southeast of the area. With wrap
around moisture and continued daytime instability over southern
and eastern portions of the area, expect additional chances for
showers and thunderstorms Friday afternoon and evening.
.LONG TERM...Sat, June 1st through Tue night, June 4th...
This long term period will feature temperatures 5 to 10 degrees
above normal, except near normal along the coast when the wind flow
is onshore. There will be a gradual warming trend that's expected to
peak along the coast Friday and across the inland west side this
weekend. Across the east side the gradual warming trend will
continue through the forecast period. Most interior valley locations
are expected to reach 80 to 90 degrees for highs this weekend.
We'll begin the long term period with afternoon and evening
instability developing along, near, and east of the Cascades
Saturday leading to showers and isolated thunderstorms. By Sunday
this area of instability will weaken and shift eastward, likely only
affecting Lake, Modoc, and southeastern Siskiyou County with a few
showers and possibly a rumble of thunder in SE Modoc County.
Thereafter, increasing westerly flow pushing into British Columbia
and Washington will bring an upper level high pressure ridge over us
followed by a flatter westerly flow that will then become southwest
to northeast oriented. This is expected to lead to a period of dry
weather over us Monday and Tuesday that appears likely to persist
through the end of the work week. Late in the week we're likely to
be affected by a cold front pushing in from the northwest leading to
a cool down with some gusty winds. BTL

.AVIATION...For the 28/18Z TAFS...
MVFR conditions along the coast north of Cape Blanco and across
central Douglas County is expected to lift and mostly dissipate
early this afternoon leading to VFR conditions at KOTH and KRBG.
Elsewhere VFR conditions are expected to prevail, except along and
east of the Cascades, where isolated MVFR to localized IFR
visibilities are expected in scattered showers and isolated
thunderstorms. Tonight through Wednesday morning MVFR to IFR
ceiling/visibility conditions are expected to return to the coast
from Port Orford northward eastward into Douglas County. BTL
&&
.MARINE...Updated 200 PM PDT Tuesday, 28 May 2019...A thermal trough
along the coast, centered to our south in California, will produce
persistent north winds for the next several days. The combination of
wind driven seas and a fresh northwest swell and a longer period
southwest swell will produce steep seas across much of the area,
beginning south of Cape Blanco this afternoon and spreading north
Wednesday afternoon. Given the long duration of the pattern, these
conditions are likely to persist well into next week. As is typical
for this pattern, winds and seas will peak during the afternoons and
evenings, with the strongest winds and highest seas expected south
of Port Orford. Model guidance are in pretty good agreement that the
thermal trough will strengthen this weekend, with gales and very
steep seas possibly developing within the southern waters by Friday
afternoon. -Petrucelli
