457 pm pdt Sun may 26 2019
updated aviation section

Short term Today through Wednesday... An upper low is currently
over central california, and this low will affect the southern
oregon and northern california weather through tomorrow at least.

Cool and cloudy conditions exist for most of the forecast area
this afternoon under deep northeasterly flow. About 40 lightning
strikes have already been observed in lake county this afternoon,
and these storms will likely spread westward with time. Some
sunshine will help increase instability and increase the chance
for some thunderstorms along and just east of the cascades. West
of the cascades there is a chance of storms to push off the
terrain, but the steering flow switches to northerly in the late
afternoon and may prevent showers storms from reaching the rogue
valley. Therefore, we have a slight chance of storms for most west
side valleys... And emphasis on the word "slight". One significant
note about the rain today is that some is expected to be heavy,
especially in lake, modoc, and eastern siskiyou counties. There's
enough agreement amongst models and post-processed guidance to
highlight this on social media and our weather story, so we have
done this. Confidence isn't high on any flooding, given no
flooding was reported in modoc county during recent heavy
rainfall, but a half inch of rain at alturas is near-record for
this time of year, so we wanted to highlight that.

Showers quiet down tonight due to loss of surface heating. On
Monday the area will still be influenced to some extent by the
large scale circulation that will be over southwest utah by then.

Upper level energy will move southward down the western edge of
the trough, traversing the forecast area during the afternoon.

This will combine with instability (much more sunshine and surface
heating Monday compared to today) to generate the chance for
thunderstorms for the eastern two thirds of the forecast area, to
include basically areas from the illinois valley and roseburg
eastward. One thing to note about tomorrow is that the convection-
allowing models (cams) and post-processed SREF calibrated
thunderstorm guidance are not showing much chance for storms west
of the cascades. Confidence is lower than normal for this part of
the forecast based on this disagreement. Normally we'd like to see
at least either the cams or SREF guidance indicating storms.

On Tuesday the shower and thunderstorm chances are confined to areas
from the cascades eastward, and on Wednesday afternoon similar
conditions are expected. Westerly flow aloft should keep shower and
thunderstorm activity in areas along and east of the cascades.

One main weather change for Tuesday and Wednesday will be a trend
towards warmer afternoon temperatures. Normal high temperatures near
medford are 76 for this time of year... And for klamath falls it's
68. We'll likely exceed those temperatures by Tuesday and warm by a
few additional degrees on Wednesday. This will only be the second
time we reach above normal readings in the past 2 weeks.

Long term Thu, may 30th through Sun night, jun 2nd... Overall,
this long term period will feature temperatures 5 to 10 degrees
above normal, except near normal temperatures along the coast when
the wind flow is onshore. There will be a gradual warming trend
that's expected to peak Saturday, june 1st with most interior
valley locations expected to reach 75 to 85 degrees for highs. In
general, precipitation chances initially along and near the
cascades will shift south and eastward with time as westerly flow
increases aloft.

More specifically, a 300mb jet maximum riding through the western
edge of the upper level trough from the northwest on Thursday is
expected to give rise to another round of showers and thunderstorms
from along and near the cascades eastward. Due to increasing NW flow
in the low levels, thunderstorms are not expected west of the
cascades.

By Friday dynamics for showers and thunderstorms will have shifted
south and east, primarily to eastern siskiyou and klamath counties
eastward.

This trend is likely to continue into Saturday, with the risk for
lightning thunder over for our area. A few showers still could form
in southern lake, SE siskiyou, and modoc counties.

By Sunday an upper level trough pushing into british columbia,
washington, and oregon may result in a push of marine of stratus and
fog inland onto the west side and provide enough dynamics along with
building heat to result in a slight possibility of showers and
thunderstorms over SE siskiyou, southern lake, and modoc counties.

Aviation For the 27 00z tafs...

the rest of this afternoon and evening... Showers and isolated
thunderstorms are expected, primarily from the cascades eastward. It
will largely be dry west of there; however, some showers may push
out over the interior west side valleys east of krbg and in jackson
county. Expect a mix ofVFR MVFR, but with local ifr in heavier
showers and thunderstorms.

Overnight through Monday morning, a mix ofVFR, MVFR, and ifr is
expected, with the lower conditions most likely to occur west of
kmfr, including koth and krbg. Conditions should improve late
Monday morning or early Monday afternoon for most areas. Then,
some additional showers and thunderstorms will develop Monday
afternoon and evening, once again predominantly from the
cascades eastward. -spilde

Marine Updated 200 pm pdt Sunday, 26 may 2019... Low pressure over
northern california and strong high pressure offshore will continue
to drive gusty north winds and wind driven seas over the waters this
afternoon. Winds and associated seas diminish rapidly from north to
south this evening and tonight as the low pressure moves farther
inland and pressure gradients relax. Relatively light winds and calm
seas are expected Monday into Tuesday morning. Then, a thermal
trough develops along the coast later Tuesday, which remains in
place through the remainder of the week and next weekend. This will
drive moderate to strong north winds and steep to very steep wind
driven seas, especially over the waters south of CAPE blanco.

Conditions are likely to be hazardous to small craft from Tuesday
afternoon on, and winds may approach gale force during the
afternoons and evenings toward the end of the period. -wright

Mfr watches warnings advisories
Or... None.

Ca... None.

Pacific coastal waters... Small craft advisory until 11 pm pdt this evening for
pzz350-356-370-376.
