235 pm pdt Tue may 21 2019

Short term Showers have filled up the radar image this afternoon,
and rainfall totals since midnight have ranged from 0.5 to 1.5
inches towards the curry county coast and western siskiyou county,
around a quarter inch for inland valleys west of the cascades,
and 0.1 to 0.25 inches east of the cascades. Another quarter to
half inch of rainfall is expected through tonight for most areas.

Looking at daily rainfall records for may 20, it looks like today
will be a top 5 rain event for medford and north bend. Snow levels
are currently between 6000 and 7000 feet, so no snow impacts to
mountain passes are expected through the rest of the day... With
the exception of cedar pass on highway 299 at 6000 feet where snow
is currently being observed on the webcam.

Precipitation pushes eastward tonight into Wednesday morning.

Wednesday will look and feel much different than Tuesday for the
vast majority of the forecast area. Both precipitation chances and
amounts will be sharply lower, and sunshine is expected in the
afternoon at least. In modoc and klamath counties, precipitation
will linger longest on Wednesday, especially for north facing
terrain where northerly flow will enhances chances for
precipitation.

Collective model guidance points to increasingly dry and warm
conditions Thursday. High temperatures Thursday afternoon will reach
near normal for the first time in about 10 days. On Friday a well-
advertised low will sink southward from washington, spreading a
chance of showers mainly to areas from the cascades eastward.

Looking at the GEFS precipitation output, this confirms the
placement of showers on the east side. However, with such a
significant feature like this upper low, it's certainly plausible
that showers could spread to areas west of the cascades too, but
we'll align ourselves with the consensus for now.

Long term Saturday through Tuesday... The general
consensus is for upper troughing to remain over the area through the
holiday weekend. This means we could be dealing with a chance of
showers and afternoon and early evening thunderstorms Saturday
through memorial day for most inland locations. In this type of
pattern we could actually end up with a fair amount of dry time in
the morning hours, especially west of the cascades. Then from late
morning through the early evening hours, the chance for scattered
showers will increase in coverage and intensity with a slight chance
of thunderstorms. The best chance for showers and storms both
Saturday and Sunday will be along and east of the cascades. However
westside locations will also have a risk for showers due to
increasing instability from daytime heating or steering winds
bringing in showers from the southeast Saturday, then east on
Sunday.

The upper low is expected to set up southeast of our area Monday.

The operational models are in relatively good agreement with the
position of the low, but the individual ensemble members show a wide
range of solutions. Therefore the details on the exact location of
showers and where the best chance of showers could change. The upper
should finally move far enough away where we could end up with drier
and milder conditions next Tuesday. -petrucelli

Aviation For the 21 18z tafs... Low pressure is moving through the
forecast area today, spreading showers across most areas. Mountain
obscuration is expected most areas through tonight. A mix of
conditions exists currently, but ceilings are generally MVFR and
will continue like this through the day. Tonight, conditions should
degrade some to low MVFR or ifr in valleys west of the cascades.

Most locations should improve toVFR by Wednesday afternoon, and
gusty north winds are expected. Keene

Marine Updated 200 pm pdt Tuesday 21 may 2019... Low pressure will
push onshore this afternoon, with west winds shifting to the north
by this evening. Meanwhile, a heavier west swell between 14 and 16
feet at 14 seconds will continue through this evening, then
gradually diminish tonight.

Offshore high pressure will rebuild Wednesday and persist through
the remainder of the week. As a result, moderate to strong north
winds will develop over the waters. Steep wind-driven and fresh
swell dominated seas are expected Wednesday through at least
Thursday night, especially south of bandon and beyond 5 nm off
shore, where hazardous seas warning conditions are expected.

Adjustments were made to the hazard headline to reflect this. Please
see mwwmfr for more details. -petrucelli bpn
