Short term Tonight through Saturday night... 2:00 pm observations
have indicated that the showers largely impacting siskiyou county
with virga everywhere are largely decreasing in coverage. This
has allowed for heating to occur across much of the area,
especially across the rogue valley. Had to increase the maximum
temperature for today already, and may still be a bit too low.

Some downsloping winds may be accounting for this as well-- things
are still relatively breezy this afternoon.

Regarding thunderstorms for this afternoon, some ensemble guidance
is still trying to indicate that thunderstorms could be possible,
but am still not enthusiastic. There seem to be cumulus clouds
anchored to the terrain as well as a general wave pattern. This is
denoted by a very intriguing GOES west visible satellite image
(channel 2). There are also some cumulus clouds occurring in
southern oregon as well, but it looks as if the tops are being
blown off. Overall, it is still not looking like thunderstorms
will occur.

Showers will diminish overnight tonight and a relatively dry day
is expected on Thursday. Then, another front approaches the
pacific northwest on Thursday night into Friday. This front will
have more precipitation with it, but still not as strong as what
was seen in the later half of february. Some models show an
occluding nature to this front, so some winds could be breezy
yet again, but other models aren't showing the same signatures
(but are still showing the winds). Overall ensemble guidance
suggests that the system on Friday will be average for this time
of year in terms of wetness and strength.

Snow levels will hover between 5000 and 6000 feet before dropping
to 4000 feet on Friday night. Additionally, precipitation amounts
have largely decreased, thus snow amounts have also decreased. We
are still not expecting much in the way of snow impacts, with the
cascades, siskiyous, and warners now seeing between 2 and 4
inches. There may be some snow on the highest passes (highway 140
at lake of the woods, highway 299 near cedar pass, highway 62 near
crater lake) with less than an inch occurring along interstate 5
at siskiyou summit on Friday night.

Conditions will become showery on Saturday as snow levels remain
around 3000 to 3500 feet. Instability will be higher on Saturday
and lis could be sufficiently negative to create a rumble of
thunder west of the cascades. The ensemble guidance shows the
highest probabilities of thunderstorms occurring across the
cascades and east of the cascades, but with low snow levels, don't
foresee a need to include thundersnow in the forecast. -schaaf

Long term Sunday through Thursday, march 24-28, 2019...

a short wave ridge will build over the area Saturday night into
Sunday. The air mass, while cold, doesn't look cold enough to have
a large impact on local agriculture, with expected lows Sunday
morning in the low to mid 30s for the west side valleys. East side
areas will have lows in the teens and 20s, but their growing season
is still a ways off.

Overall, dry, mild weather is expected Sunday afternoon with highs
in the low to mid 60s west of the cascades and in the low to mid 50s
over the east side. Locally breezy conditions (from the sse) may
develop in the shasta valley.

The next front offshore will approach the coast Sunday night, then
move onshore Monday. There should be a period of gusty south to
southeast winds in advance of the front, especially in the typical
locations like the shasta valley, the southern end of the rogue
valley and over the east side. A period of steadier precipitation is
expected to accompany the front, especially from the coast ranges of
sw oregon to western and central siskiyou county, where there could
be 0.50-1.50 inches of liquid precipitation. Amount will be much
lighter farther north and east across the cwa. Snow levels at this
time look to be around 4500 feet, with most accumulating snow above
5000 feet.

Broad SW flow aloft will set up Monday night with a closed
low out near 130 W wobbling offshore of wa or Tuesday and
Wednesday. This will maintain unsettled weather for much of the
balance of next week with another frontal system moving onshore
Tuesday and Tuesday night. This front appears very similar to
its predecessor, with the bulk of the moisture precipitation
expected across our southern and western zones. A showery
pattern continues Wednesday through Thursday, but showers
gradually diminish in coverage and intensity as the closed low
offshore opens up and moves onshore. -spilde

Aviation For the 20 18z tafs... A wave of low pressure will
continue to move through the area today bringing showers, most
numerous in california and far southern oregon, but primarily
focused in the mount shasta area. While partial mountain
obscurations will occur across the area throughout the day, MVFR
valley ceilings are expected in the mount shasta area. This
evening through tonight, the showers will taper off.

Periodic brief MVFR is possible for much of the forecast area,
especially for the coast and umpqua basin late this evening
through tonight. -btl bpn

Marine Updated 200 pm pdt Wednesday, 10 march 2019...

a small scale low will make its way up the coast this evening
through Thursday morning, producing breezy south winds and steepened
seas. This feature is trending much weaker than yesterday, with a
slightly more inland track, which would keep conditions just under
small craft advisory levels. However, should the low track slightly
farther offshore, it is possible that conditions may temporarily
reach advisory criteria, particularly around and downwind of
headlands and capes.

Long period swell will begin to build into the coastal waters late
Thursday, ahead of a front that is expected to produce south gales
and very steep wind driven seas as it sweeps through the coastal
waters Friday morning though Friday afternoon. Elevated long period
west swell will continue through Saturday and into Saturday night,
producing hazardous bar conditions and higher than average surf
before diminishing Sunday morning.

After a brief break in the action Sunday, model solutions depict
another robust frontal system passing through the region Sunday
night or Monday. Timing and strength remain uncertain due to the
possible tracks of the central low, but there is good confidence
that conditions will deteriorate by Monday morning, with gales and
very steep seas possible with the passage of the front. Expect
forecast updates over the next day or two as details become more
clear. -bpn
