Synopsis for the southern oregon coastal waters.. Gusty north winds and steep, choppy seas will persist today and then diminish tonight as high pressure builds in from the west. Calmer conditions will then occur Monday through Tuesday morning as high pressure builds in stronger from the west. The thermal trough is expected to return Tuesday afternoon producing gusty north winds and steep seas south of cape blanco that are likely to persist through the latter half of the week.

852 am pdt Sun may 26 2019

Discussion The active, cool weather pattern continues. Rainfall
totals were generally between 0.25 and 0.75 inches across most of
the forecast area. Lesser amounts generally were observed at the
immediate coastline and far northern lake county. Snowfall was
observed all the down to around 4000 feet at siskiyou summit on
interstate 5, and about 12 inches of snow was observed near
tennant ca in eastern siskiyou county. We estimate around 6 inches
fell at crater lake. Interestingly, the record daily snowfall
amount for may 26 is 20 inches! So this late may snowfall is not
all that unusual... Moreso though for those lower elevation
locations like siskiyou summit.

The air mass will warm significantly this afternoon as the upper
low responsible for the rain and mountain snow moves south and
away from the forecast area. This will also mean some sunshine for
the forecast area early this afternoon. Sunshine is more likely
along and west of the cascades than on the east side. Convection-
allowing models (cams) are suggesting increasing showers with some
thunderstorms this afternoon, thanks in part to some surface
heating and resulting instability, and also due to general
diffluence in upper level winds. Steering winds for storms will be
from the north-northeast, so some storms could come off the
cascades and into west side valleys. Also, local instability is
not high but probably enough for a few storms, with CAPE values
forecast to be around 400 j kg in eastern jackson and douglas
counties.

Additionally, both the morning NAM and WRF arw nmm show some heavy
rain over southern lake, modoc, and eastern siskiyou counties this
afternoon and evening, so we added a mention of heavy rain in the
forecast there.

All this considered, the forecast looks to be in good shape this
morning. Please see the previous forecast discussion below for
more details on the rest of this weekend's weather.

Aviation For the 26 12z tafs... Widespread MVFR is expected
through late this morning with local ifr, periods of rain and
terrain obscured. The lowest cig vis is expected between from now
through 26 1600z with gradual improvement in the late morning.

Freezing levels will be low enough that icing should be expected
down to about 4kft msl this morning, especially along and near the
cascades. This afternoon and evening, expect showers along with a
slight chance for thunderstorms for areas inland of the coastal
mountains. Conditions should be mainlyVFR for most locations this
afternoon, but areas of MVFR will persist, especially in and near
showers t-storms. MVFR CIGS will become widespread along the coast
and into the umpqua basin late this evening into tonight with areas
of MVFR elsewhere in showers. -cc

Marine Updated 845 am pdt Sunday, 26 may 2019... Steep seas
driven by gusty north winds will be the primary concern across all
of our coastal waters area today into tonight. These gusty north
winds are expected to reach small craft advisory levels south of
gold beach. Winds will then gradually diminish this evening
through tonight, lowering to 5 to 15 knots by sunrise Monday
morning. Seas will correspondingly improve overnight through
Monday morning. Light winds and calmer seas are then expected
Monday through Tuesday morning as high pressure builds in from the
west. The break will be brief, however, as north winds are
expected to increase once again Tuesday afternoon due to the re-
development of the coastal thermal trough. As a result, gusty
north winds and steep seas are likely south of CAPE blanco Tuesday
evening through the latter half of the week. Btl cc

Prev discussion issued 431 am pdt Sun may 26 2019
discussion... Snow levels are even lower than expected with snow
mixing with rain in mt. Shasta city (near 3500 feet) and klamath
falls (near 4100 feet). Based on the odot and caltrans cameras, most
of the passes were wet rather than snow covered due to road
temperatures above freezing.

Generally, snow levels were near 4500 feet with accumulating snow
nearly 1000 feet higher depending on snow rates. A winter storm
warning will continue through 8 am above 5500 feet in the mt.

Shasta region while a winter weather advisory continues until 8 am
for the southern cascades including highway 140. Based on the
highway web cams it looks like snow was accumulating on the roads
at green springs and dead indian memorial summit.

At 430 am, radar showed the center of the low's circulation
south of redding. By noon, this center of circulation should be
close to sacramento with precipitation diminishing across southern
oregon and far northern california, although bands of
precipitation will likely continue into modoc county.

Based on the hrrr model the low's circulation will still influence
our weather later today with showers and thunderstorms developing
across the eastside and cascades. Storm movement will be from the
northeast to southwest so even the rogue valley could see storms
move off the cascades very late in the afternoon or early
evening.

For Monday, both the ECMWF and GFS models have consistently been
showing a disturbance moving from north to south across our region
during the afternoon and evening. This disturbance should trigger
a redevelopment of showers and thunderstorms across inland areas
possibly as far west as the illinois valley.

After Monday, the forecast becomes more ambiguous regarding
showers and thunderstorms with more confidence for warmer
temperatures near or a little above normal. Generally, afternoon
and evening thunderstorms are possible from the cascades east from
Tuesday through Thursday. Weak upper ridging may build Friday
into Saturday for more stable and drier conditions along with
above normal temperatures.
