.AVIATION...16/00Z TAFs...VFR conditions will prevail through the
TAF period for most locations. A mix of high and mid level clouds
will continue streaming over the region, and this should limit fog
development for most areas. There could be a brief period of LIFR
conditions in fog at North Bend and Roseburg early Monday morning,
but confidence is low in this occurring. /BR-y

DISCUSSION (Today through Saturday)...

Key Points:

* Relatively quiet conditions the next 7 days
    - No notable impacts expected
    - Only very light rainfall along/near the coast next week

* Well above normal temperatures possible this week
    - 10-20 degrees above normal
    - Several climate sites have records in jeopardy

Further Details:

High pressure aloft will continue to slowly slide east today and
tomorrow, eventually parking over the west coast for several days.
This will lead to very warm temperatures for this time of year with
several locations potentially breaking previous daily record highs.
For perspective, last year in Medford on St Patrick`s Day we were 52
for the daytime high, but this year we will be very close to 80.
Normal high temperatures for Medford on March 17th is 60 degrees
which means we will be about 20 degrees above normal this year,
and 30 degrees warmer than last year. Starting Monday, and going
through Friday, mid/upper 70s and even low 80s will be common
across the area. However, coastal areas will likely only be in
the 60s to perhaps low 70s, but this is still above normal for
this time of year. Overall, a warm stretch of weather will be
noted for the next several days.

We are not expecting much rainfall through this stretch. However,
the NBM does bring chances Tuesday onward when we could see very
light rainfall/drizzle along and near the coast. That said, very few
ensemble members have rainfall next week, so these PoPs from the
NBM are likely overdone given the lack of QPF in the individual
ensemble members. What is more likely is mostly cloudy skies that
stick around to regulate temperatures cooler than inland areas with
very little actual QPF produced.

MARINE...Updated 100 PM PDT Sunday, March 15, 2026...North winds
ease today under improved conditions and will eventually shift to
southerly by tomorrow. Seas build Tuesday as a westerly swell
moves through the waters, but conditions are expected to remain
below advisory conditions. In fact, conditions are generally
expected to remain below advisory conditions through much of next
week. However, by Saturday a thermal trough looks to develop and
will bring gusty northerly winds with steep seas likely for all
waters.
