DISCUSSION

To a large extent, considering the full range of summer-time possibilities, the weather in our area during the next week will be of low impact. A notable trend in the latest data is toward better model agreement with greater confidence in dry weather during the middle and latter portions of this week. A trough dominated pattern will keep our temperatures at least slightly on the cool side while associated moisture and any instability in the air mass will be meager.

There is a slight chance to chance of very light showers for Coos and Douglas counties northward through this evening, mainly near and over the higher terrain with amounts of a trace to 0.03 inches expected to be common.

Low clouds early this morning are most extensive for Coos, Douglas, and Josephine counties. Some lifting of the cloud cover and breaks are expected during the day. But, cloud cover will be focused in that area through Wednesday morning, particularly during the night and morning hours. Though less widespread elsewhere, cloud cover is at maximum this morning and skies will not necessarily be clear early this week. That cloud cover is hindering cooling in the Klamath Basin, with temperatures in the mid to upper 30s. Less cloud cover for south central Oregon and northern California, but very similar morning lows are expected on Monday morning.

Temperatures are forecast to remain quite cool today, and remain at least modestly below normal through Thursday. But, exhibit a gradual warming trend into Saturday/Independence Day. As a good proxy for the character of inland temperatures, the high in Medford a few days ago/Thursday was 90 and it will likely be more than a week, on Friday or Saturday, before it reaches 90 here again. Inland lows around 40 on the east side and around 50 on the west side are expected to be common through Thursday. Meantime, highs generally in the upper 60s today will trend to the mid to upper 70s on Monday and still be only in the lower 80s on Thursday.

Northwest winds this week do look to be consistently breezy during the afternoon and evening hours, around to slightly above typical strength. Rather than 10 to 15 mph with gusts up to 25 mph, values of 10 to 20 mph with gusts up to 30 mph will be common.

Besides the mainly night and morning, mainly western Oregon, low clouds, the aforementioned upper level troughs will bring a widespread increase in high clouds on Monday and Thursday.

Confidence is also high in temperatures reaching a peak on Saturday, accompanying a brief period of ridging. From Day 7/next Sunday onward into Day 10, model solutions more noticeably diverge between a majority contingent favoring a continued westerly flow aloft and stable airmass with temperatures remaing slightly above normal and the jet stream aimed at western Canada, or about 15% of GEFS and ECMWF ensemble members indicate deeper troughing aloft with a possible introduction of southerly flow aloft and development of afternoon instability/some thunderstorm chances in some portion of our area.

AVIATION...28/12Z TAFs

Areas of MVFR and mountain obscuration are present in southwest Oregon this morning, especially north of the Umpqua Divide in Coos and Douglas counties. These ceilings are expected to lift to VFR for the afternoon and early evening, then areas of MVFR are expected again late tonight into Monday morning. A chance of light showers will also persist for Coos and Douglas counties today (including North Bend and Roseburg), favored near north facing slopes.

Elsewhere, VFR will persist into Monday morning. Cloud cover will diminish during the day today, then ceilings develop again over much of the remainder of southern Oregon.

MARINE...Updated 200 AM PDT Sunday, June 28, 2026

Gusty north winds will maintain borderline steep seas across all areas this morning. North winds are strengthening, and will result in very steep and hazardous seas from Gold Beach southward this afternoon and evening. A brief period of gale force gusts is possible south of Brookings and within 20 nm from shore. This pattern will further strengthen Monday through Tuesday evening, with gales likely south of Nesika Beach. Elsewhere, northerly winds and fresh northwest swell may continue steep seas into Thursday. Winds ease slightly with improving conditions late in the week.
