Oregon skies hang gray and damp this morning, and drivers already see mist clinging to windshields along I-5. Temperatures sit near 41 degrees at Portland International Airport, with overcast clouds locking in a cool, late-winter feel.
According to the National Weather Service in Portland, a 10% chance of rain develops after 4 p.m. today as highs reach 59 degrees. Conditions stay mostly cloudy, and light winds keep the air chilly. Patchy fog may form toward early Monday, especially in low-lying areas near the Columbia River.
Monday brings a 20% chance of rain after 10 a.m., then partial afternoon clearing with highs near 60. The real shift arrives Tuesday. Rain becomes likely after 10 a.m. with a 70% chance and highs near 55 degrees. South-southwest winds increase to 6–10 mph, with gusts up to 20 mph. By Tuesday night and Wednesday, rain chances jump to 100%.
Expect steady wet pavement on I-84, Highway 26 and city streets through midweek. Plan extra stopping distance and allow more commute time. While valley temperatures remain above freezing, higher elevations in the Cascades will see accumulating mountain snow. Travelers heading east should monitor pass conditions closely.
This is a classic early March pattern. Systems roll in from the Pacific, delivering rounds of rain before a gradual warming trend late week. Highs hold in the lower to mid-50s through Thursday, then moderate heading into the 6–10 day outlook.
We also gain nearly 70 extra minutes of daylight this month. Clocks spring forward at 2 a.m. March 8, bringing brighter evenings just as spring vibes slowly build.
