Portland, Oregon weather forecast for Thursday, May 12

PORTLAND, Ore. (KOIN) — Goodbye and farewell to the sun and dry weather. We reintegrate the rain and not only that – the wind.

Thursday will start cloudy and humid. Showers sweep through the Portland metro area as early as 5 to 6 a.m. The wind will pick up steam throughout the morning as a cold front pushes steadily eastward. Rain jackets will come in handy today. If you’re thinking of hitting the road by bike, you’ll also need rain gear.

Scroll through the graphs below to see the timing of the rain and the likely amount by the end of the day. The wettest part of your day is going to be from late morning to midday. This system will bring rain for all. You can tell by lunchtime that the rain will encompass Wasco County and Jefferson County, in addition to spreading into Deschutes County.

The wind will blow into the area from the south. Stronger for the Oregon Coast in the morning with some gusty times in the valley. A more consistent wind will pick up closer to midday, with gusts trying to work into the 30 mph range from Hillsboro to Canby.

If you’re one of the few people here who likes using umbrellas, better get a sturdy one!

And the temperatures? It’s going to be one of the coolest days this month – and that’s saying a lot!

Temperatures in the 40’s by the time you walk through the door. Temperatures sit in the 50s in the afternoon. Even with this strong southerly wind, the cold air behind the front will keep us from getting much warmer today.

The hottest areas in the region will be in the lower Columbia basin. This will make it the 11th day of this month below average. The high temperature should be closer to 70 degrees now.

Stay dry and warm!
