.AVIATION...07/06Z TAFs...VFR conditions are present with high
clouds moving south. Some pockets of clearing from the high clouds
could allow for fog and LIFR conditions to form around Grants Pass
or other smaller valleys. However, the higher clouds are favored
tonight. There is a low chance of some coastal showers through the
TAF period and MVFR conditions are possible along the coast.

.MARINE...Updated 800 PM PST Saturday, March 7, 2026...Swell
dominated seas will persist into early Saturday. Meanwhile, north
winds will lead advisory conditions this weekend south of Gold Beach
as a thermal trough builds off the California coastline. Winds are
gusting up to 35 knots near Buoy 27 and that will likely persist
most of this weekend. Wind drive seas should also cover most of the
southern Oregon coast through the weekend. Areas of very steep seas
are possible from Brookings southward on Monday. Improving
conditions are possible around mid-week.

.PREV DISCUSSION... /Issued 208 PM PST Fri Mar 6 2026/

DISCUSSION...Northerly flow aloft under the leading edge of a
Pacific ridge is the guiding feature for area weather today. Mid and
high level clouds are reaching the northern border of the CWA but
are generally breaking up by the time they reach northern
California. This flow is keeping slight chances (20-40%) of
precipitation along the Oregon coast north of Cape Blanco through
this evening. Other areas will see seasonable daytime highs under
those passing clouds. These clouds are minimizing chances for fog
development overnight, although patchy fog may develop in some low-
lying areas.

That ridge flattens and expands over the area over the weekend,
bringing daytime highs 5 to 15 degrees above normal. Most areas will
see highs in the low to mid 60s through the weekend. Low elevation
inland areas in Curry County (Ex: Agness, Brookings) have a 70-90%
chance to see highs exceed 70 degrees. Parts of the Klamath River
Valley may see similar temperatures. On Sunday, the Pacific ridge is
further compressed from the north by a low pressure system moving
into the Gulf of Alaska. This will allow Coos, Curry, and Douglas
counties to see a few degrees of daytime cooling while highs in
Siskiyou and Modoc counties rise. This brings 70-90% chances to
exceed 70 degrees to Highway 89 (McCloud) as well as 50-70% chances
around Adin and south of Alturas.

A Gulf of Alaska low lingers above the Pacific ridge to start next
week, bringing zonal/slightly northwest flow aloft. Cold air
advection to start to week will bring seasonal daytime highs on
Monday and Tuesday, generally in the low to mid 50s across the area,
and cool nighttime lows. For Monday night into Tuesday morning, low
temperatures may reach freezing levels for west side valleys. Snow
levels have come up slightly (in the 2000-3000 foot range on Tuesday
morning and afternoon) and slight precipitation chances limited to
the Oregon coast and Cascades north of Lake of the Woods.
Significant winter impacts are not expected.

While a zonal flow pattern looks to continue into midweek and
beyond, there`s some uncertainty in how moisture will move along the
zonal flow. The chances of moisture moving to our area from the
Pacific is keeping slight but constant 20-40% chances for light
showers along the Oregon coast and Cascades through much of next
week. In the absence of an atmospheric lifting mechanism, shower
chances for other areas are minimal. Towards the end of the week,
long-term models diverge in their expectations. GFS meteograms keep
zonal flow in place, with a few pulses of moisture bringing west
side shower chances for next weekend. ECMWF ensemble members favor a
strengthening ridge with dry conditions and warmer temperatures. At
this point, nothing in the long-term forecast resembles a hazardous
pattern. -TAD
