KEY POINTS

* Seasonable temperatures with dry conditions will persist through the remainder of the week.

* Shortwaves moving through the region will bring enhanced west to northwest afternoon winds along with nightly marine pushes along the coast and into the Umpqua Basin.

* Temperatures trend below normal over the weekend. Light rain possible along the coast and north of the Rogue-Umpqua Divide on Saturday.

* Above normal temperatures are likely to return Tuesday and persist through much of next week.

DISCUSSION

Satellite imagery shows widespread cumulus across southern Oregon and clear skies over northern California. Some light showers continue along the Cascades, mainly north of Crater Lake. Afternoon temperatures are trending 10 to 20 degrees cooler than this time yesterday, and we expect seasonal highs today (low 70s West/mid- upper 60s East). Low pressure is departing to the east today, which will bring decreasing clouds, easing winds and an end to the shower activity by this evening. Wind gusts over the last 24 hours peaked in the 20-30 mph range for areas west of the Cascades, with 35-45 mph common east of the Cascades and across northern California. A weak front brought some light rain the region early this morning, focused along the coast (0.25"-0.40"), coastal ranges (0.25") and into the Umpqua Basin (few hundreths - 0.10"). There was some light sprinkles across Jackson County and northern Klamath/Lake Counties as well, but only a few sites measured any precipitation.

Zonal flow will persist through the end of the week, resulting in seasonable temperatures and dry conditions. Afternoon highs will trend a few degrees warmer Thursday and Friday, and overnight lows will hover near seasonal norms. Shortwaves passing through the region Thursday and Friday will bring enhanced west to northwest afternoon winds along with nightly marine pushes along the coast and into the Umpqua Basin.

Over the weekend, a broad trough carves out over the Pacific Northwest, which will bring another cooling trend with afternoon highs being somewhat below normal. Shortwaves within this broad trough will provide glancing precipitation chances across northern/northwestern areas Saturday and Saturday night. The overall chance for any widespread wetting rainfall is low at this time, but we'll have to watch model trends with this trough to see if there are any southward or westward shifts in shortwaves.

Early next week, heights build over the region, so we'll see a warming trend in high temperatures. There's differences among the guidance with about 30% of the solutions showing a more amplified pattern with high pressure over the eastern Pacific and an elongated trough over the Intermountain West. Meanwhile, about 55% of solutions show a less amplified pattern but bring the high pressure closer to the Pacific Northwest. Either outcome will bring a warming trend, but the extent remains uncertain. The remaining 20% of solutions have the pattern shifted farther west, which would maintain more seasonable temperatures for the early part of next week. Stay tuned as details become more clear over the coming days.

AVIATION...13/18Z TAFs

VFR conditions prevail across the region this morning with scattered to broken cumulus most concentrated north of the OR/CA border. Isolated to scattered showers and terrain obscurations persist along the Cascades and in the Umpqua Basin. The overall trend will be for decreasing cloud cover moving into the afternoon with breezy south to southwest winds turning west to northwest this afternoon. VFR conditions will prevail through the TAF period for most areas, though MVFR ceilings are expected along the coast and into the Umpqua Basin tonight into Thursday morning.

MARINE...Updated 1130 AM PDT Wednesday, May 13, 2026

Showers will diminish through the afternoon with west to southwest winds persisting. Swell dominated seas will increase some this afternoon, but overall conditions are expected to remain below advisory criteria today.

Northerly winds return tonight into early Thursday, increasing some Thursday afternoon into Friday. Borderline advisory level winds are possible south of Gold Beach Thursday and Friday afternoons, which could lead to brief periods of steep seas on Thursday within 25 nm of shore. Steep seas and conditions hazardous to small are more likely on Friday afternoon as a slight increase in northwest swell combines with wind seas to bring elevated wave heights.

North winds persist into the weekend with more widespread advisory level wind speeds possible south of Cape Blanco. Meanwhile, a higher (7-9 ft) northwest swell builds into the waters over the weekend. Steep seas will be possible south of Cape Blanco where this increasing swell combines with wind driven seas, while north of Cape Blanco, swell dominated seas should result in below advisory conditions.
