The National Weather Service forecast increased mid- and upper-level cloud cover across the region on Monday. Highs Tuesday and Wednesday are expected to be in the upper 60s to low 70s.

Clouds Today, Warmth Tuesday And Wednesday

The National Weather Service Portland forecast points to low precipitation chances and light winds. Overnight lows are expected to be in the low 40s for most locations.

Wednesday looks like the week’s best bet for outdoor plans, with sunshine, light winds and a high in the upper 60s to low 70s. The warmup is brief, though, with temperatures sliding back toward the low 60s by Thursday.

Rain Chances Return Late This Week

A slight chance of rain is forecast Friday, with rain also possible Saturday.

Saturday brings a chance of rain, with daytime highs around 61 to 64. Sunday looks mostly sunny with a high near 62, with rain chances increasing late Sunday night, so weekend plans may need a backup option.

Forecast Hints At A More Active Weekend

The latest forecast discussion also raises the possibility of a stronger system next weekend, potentially bringing heavier rain and gusty winds across the region, although confidence remains low this far out. That is a meaningful update to Hoodline’s earlier Portland forecast, which had already pointed to a midweek warmup and late-week showers.
