DISCUSSION

Key Points:

*Localized AM frost possible east of the Cascades this morning.

*A gradual warming trend is expected through Thursday. Dry weather is likely. However, weak instability and moisture may bring some cumulus build ups to southeast Lake County on Tuesday.

*Breezy to gusty north to northwest winds are expected in the afternoons and evenings through Thursday.

*Friday into Saturday, a weak high pressure ridge will bring warmer than normal temperatures and continued dry weather. Temperatures will peak on Saturday with highs around 5 to 8 degrees above normal.

*Temperatures trend slightly cooler on Sunday as the ridge shifts east and a trough approaches.

An upper low centered to the northeast over northern Montana will continue to shift eastward while a broad trough remains over the Pacific Northwest. Cool morning temperatures are expected for areas east of the Cascades and localized or brief frost may develop in the Klamath Basin and surrounding areas. Otherwise, expected mild daytime temperatures across the area today with dry weather with breezy to gusty afternoon and evening winds.

Temperatures trend slightly warmer Tuesday. Additionally, a shortwave moves into the area from the northwest on Tuesday. This will bring a marine push into coastal areas and the Umpqua basin Tuesday morning with a very low chance for light showers (5%). Some weak instability and mid level moisture may result in some cumulus buildups over far southeast Lake County on Tuesday afternoon but chances for any showers or thunderstorms are very low (5%). Additionally, enhanced afternoon/evening northwest winds are expected Tuesday.

Warm and dry weather is expected Wednesday. Temperatures trend slight warmer into Thursday, reaching near normal values. Another weak shortwave trough moving north of the area may result in enhanced afternoon breezes on Thursday and some cumulus buildups, mainly east of the Cascades and in Northern California. However, chances for showers or thunderstorms are forecast to remain very low (5% or less).

Friday into Saturday, weak ridging develops across the region. This will result in a stronger warming trend. Temperatures are expected to peak on Saturday with highs 5 to 8 degrees above normal. High temperatures in the upper 80s to mid 90s are likely for most inland valleys on Saturday. Then, the high pressure ridge moves eastward on Sunday as an upper trough pushes in from the northwest, resulting in a slightly cooling trend and a potential for enhanced northwest breezes on Sunday.

AVIATION...29/18Z TAFs

VFR levels persist across northern California and southern Oregon late this morning. Northerly flow continues to push clouds into Douglas and Coos counties. Ceilings at North Bend and Roseburg may periodically reach MVFR levels, but this is not generally expected during the day. The Umpqua Divide is keeping these clouds from traveling farther south. Some midlevel cumulus is developing over terrain in Jackson County. MVFR ceilings are possible along the coast and into the Umpqua Valley overnight. There's a slight chance of these ceilings reaching Medford if the clouds can spill over terrain. Any MVFR ceilings that develop overnight look to dissipate by the end of the TAF period. -TAD

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

Gusty north winds continue this morning, with very steep and hazardous seas from Gold Beach southward. North of these areas, incoming swell and north winds will maintain steep seas. This pattern will further strengthen Monday afternoon through Tuesday evening, with gales expected to develop south of Gold Beach. Elsewhere, northerly winds and strengthening northwest swell will continue steep seas through Tuesday evening. This pattern may persist into Wednesday. Winds ease slightly Thursday and Friday with improving conditions.
