.DISCUSSION.../Issued 1248 PM PDT Tue Mar 24 2026/

The front is arriving, with rain spreading inland to
the Cascades and winds picking up across the region. A Wind
Advisory has been issued for far eastern Klamath County and Lake
County from late Tuesday morning into Tuesday evening, with
southwest winds of 25 to 35 mph gusting up to 55 mph. As is
typical in a southwest flow pattern, winds are expected to be
strongest near Winter Rim, including the Summer Lake to Silver
Lake vicinity. Wind speeds will also be elevated over the Warner
Mountains of eastern Modoc County.

Very little if any rain is expected to make it to the East Side
with this front, with light rain over the West Side and western
Siskiyou County, and periods of moderate rain at the coast and in
the upper Umpqua Basin. Overall, precipitation is expected to
continue through this evening and into tonight, and with high snow
levels, no winter impacts are expected, even in the mountains.

Remnants of the front will linger Wednesday into Thursday with
cooler temperatures that will be closer to seasonal normals, and
isolated to numerous light showers, still limited to the Cascades
and West Side in Oregon and far northwest Siskiyou County.

Warmer and drier afternoon conditions return late in the week
through next weekend, while clear to mostly clear skies under a
building ridge allow for a wider diurnal range (colder morning
lows). Based on NBM minimum temperature probabilities, and depending
on your specific location, there is a roughly 50 to 80 percent
chance of frost and/or freezing conditions for the inland West
Side valleys of Oregon Wednesday night and Thursday night. WHile
this is not uncommon for March, it does follow a period of record
warmth that ushered in early spring growth, and this sensitive
vegetation may be damaged by the cold temperatures. Colder areas,
such as the East Side, the Scott Valley, and the Shasta Valley
are still well within the cold season, and are almost certain to
freeze.

The outlook is for a more active, but also more complex pattern
of onshore flow early next week. The details of any particular
fronts or periods of rain chances will depend on how and when a
large blocking ridge over the northern Pacific occurs. Overall, it
does look like flow will trend more from the southwest, which
would result in an active, wetter pattern and cooler, more
seasonable temperatures.

.AVIATION...25/06Z TAFs...Bands of rainfall continue to move over
areas west of and along the Cascades, with isolated showers reaching
northern Klamath County. This rainfall is occasionally bringing MVFR
to IFR flight levels to the North Bend, Roseburg, and Medford
terminals. Activity continues into early Wednesday morning but eases
as time passes. A weak upper disturbance looks to follow the front
and bring increased winds on Wednesday afternoon into the end of the
TAF period , especially east of the Cascades. This front will also
bring some slight shower chances to the Coast and Cascades. -TAD

.MARINE...Updated 1245 PM PDT Tuesday, March 24, 2026...A cold front
will produce south gales and very steep seas north of Cape Blanco
today, with steep seas south of Cape Blanco. Steep seas linger this
evening while winds veer to west and diminish. Seas become swell
dominated tonight while slightly and briefly diminishing into
Wednesday morning.

A thermal trough will develop Wednesday afternoon and evening, then
strengthen on Thursday with  strong winds south of Cape Blanco along
with steep to very steep, wind wave dominated seas. Northwest winds
in the  waters south of Cape Blanco are likely to reach Small Craft
Advisory strength Wednesday afternoon and evening, then gales are
possible Thursday afternoon through Thursday night. For the waters
north of Cape Blanco, winds and seas are likely to reach small craft
advisory levels Thursday afternoon and continue into Thursday night.

The thermal trough is expected to push slightly offshore late
Thursday night into Friday with the strongest northerly winds
becoming limited to the outer portion of the waters while fresh
swell likely also continues steep seas in the inner waters.
Improvement is likely late Saturday into Sunday.  Conditions are
likely to deteriorate again early next week as the pattern becomes
more active.
