DISCUSSION

Forecast confidence for the next 6 days, for this week, is higher than typical. High clouds increase today ahead of a weakening cold front on Tuesday. The front will bring slight cooling and higher humidity with light rain in southwest Oregon and into far northwest Siskiyou County, and gusty southwest winds for the higher terrain and also east of the Cascades. A Wind Advisory has been issued for far eastern Klamath County and Lake County from late Tuesday morning into Tuesday evening, with southwest winds of 25 to 35 mph gusting up to 55 mph. As is typical in a southwest flow pattern, winds are expected to be strongest near Winter Rim, including the Summer Lake to Silver Lake vicinity. Wind speeds will also be elevated over the Warner Mountains of eastern Modoc County.

Remnants of the front will linger Wednesday into Thursday with cooler temperatures that will be closer to normal, and isolated to numerous light showers...still limited to southwest Oregon and far northwest Siskiyou County. Warmer and drier afternoon conditions return late in the week through next weekend, while clear to mostly clear skies under a building ridge allow for a wider diurnal range (colder morning lows). Based on NBM minimum temperature probabilities, this includes an expectation of freezing early morning temperatures east of the Cascades beginning Wednesday night, with a slight chance to chance of freezing for inland portions of the west side on Wednesday night and Thursday night...except a likelihood for the Scott Valley, Yreka area, and Illinois Valley. The outlook is for a more active, but also more complex pattern of onshore flow next week (day 8 to 14) to end March and start April. Uncertainties include the extent to which the upper level flow will split and the timing and track of the most vigorous pieces of energy.

AVIATION...23/12Z TAFs

VFR conditions are expected to continue today into Tuesday morning, with mid and high level clouds ahead of a cold front. Ceilings around 15000 feet msl will lower to around 9000 feet msl this evening. The probability of rain will increase in southwest Oregon Tuesday morning, though with thickening ceilings mostly remaining VFR.

MARINE...Updated 200 AM PDT Monday, March 23, 2026

A thermal trough will continue gusty north winds early this morning, except not near shore south of Gold Beach. But, wind waves and fresh swell are continuing steep to very steep seas. Conditions gradually improve later today into tonight. Steep to very steep seas return late tonight into Tuesday evening, with gales accompanying a cold front and developing north of Cape Blanco. Swell dominated seas follow late Tuesday evening into Wednesday and may remain steep.

A thermal trough is likely to return late Wednesday through Saturday. It will result in stronger northerly winds that will be strongest south of Cape Blanco, with steep to locally very steep seas possible. Conditions are likely to improve early next week immediately ahead of a shift to a more active, more seasonable pattern.
