Several Cities May Break Daily Temperature Records This Week

MEDFORD, Ore. (Feb. 4, 2026) — A persistent ridge of high pressure parked over Lake Tahoe is maintaining an extended stretch of dry, mild weather across southwest Oregon and northern California, setting the stage for several communities to challenge daily high-temperature records this week.

Satellite imagery Wednesday morning showed pockets of fog and low clouds in typical locations — the Umpqua Valley, portions of the Illinois Valley and around Grants Pass — but forecasters said those should clear by mid-morning, leaving sunny skies with high clouds developing in the afternoon.

Temperatures are expected to be unseasonably warm over the next few days, prompting the National Weather Service to highlight a number of daily record highs for early February that could be tied or beaten:

Wednesday, Feb. 4:

• North Bend, Ore. — 71°F (record set in 1993) — probably safe from breaking.

• Roseburg, Ore. — 68°F (1958) — probably safe.

• Medford, Ore. — 74°F (1984) — probably safe.

• Montague, Calif. — 67°F (1984) — probably safe.

• Mount Shasta City, Calif. — 67°F (1984) — has a decent chance to tie or break.

• Klamath Falls, Ore. — 61°F (2018) — has a decent chance to tie or break.

• Alturas, Calif. — 65°F (1995) — has a decent chance to tie or break.

Forecasters said that the warmest air aloft is expected Thursday, Feb. 5, making it the most likely day of the week for record highs, although high cloud cover could temper peak temperatures. Record daily highs for that date include:

Klamath Falls — 59°F (1995) — most likely to be reached or exceeded.

• Mount Shasta City — 66°F (2007).

• Montague — 68°F (1995).

• Alturas — 64°F (2015).

• Medford — 70°F (1963).

• North Bend — 68°F (1926).

• Roseburg — 67°F (1941).

As the ridge axis shifts east toward Idaho, Nevada and Utah on Thursday, winds will strengthen from the south, further reinforcing the mild pattern.

Looking ahead: A weak low-pressure area may develop over southern California by Friday while a Pacific trough pushes toward the Pacific Northwest coast. Most inland areas are expected to remain dry, though coastal regions could see light rain or drizzle.

By late Friday into Saturday, rain chances are expected to increase as the next frontal system approaches, and forecasters say the strongest precipitation — along with falling snow levels — could arrive Sunday into Monday. Snow levels may drop to 3,500–4,000 feet by Monday morning, potentially affecting travel through mountain passes.
