Portland Braces for Another Wet Tuesday, Storms Possible

It looks like Portland’s rain‑watch isn’t over yet. As we head into Tuesday, the sky will stay mostly overcast, and the air will feel that familiar Pacific Northwest dampness that makes you want to grab a coffee and a good book.

Morning temperatures should start around the low 50s, gradually climbing to the mid‑60s by early afternoon. It’s not hot enough to feel summer, but it isn’t the bone‑chilling cold of winter either—just that comfortable, slightly brisk vibe you get when the sun peers out just a little.

Rain chances are modest but not negligible. The National Weather Service is putting a 30‑40 % probability of precipitation on the board, mostly after noon. Think of it as those occasional drizzles that make sidewalks glisten, rather than a full‑blown downpour.

What’s more interesting is the thunderstorm potential. Models are indicating a few scattered thunderstorms could fire up in the late afternoon, especially over the eastern suburbs where the hills help lift the air. Those storms, if they do form, will probably be brief—maybe a rumble of thunder and a quick splash of rain—nothing that will cause major disruptions.

For those planning outdoor activities, it might be wise to keep an eye on the sky. A quick glance at the radar around 3 p.m. will tell you if the clouds are gathering for a brief showdown. If you’re heading out for a hike in Forest Park or a walk along the Willamette River, a light raincoat or a waterproof jacket could be a smart move.

Drivers should also stay alert. While the rain isn’t expected to be heavy, the roads can get slick quickly when the drizzle hits, especially on bridges and overpasses that stay damp longer.

In short, Tuesday won’t be a sunshine‑filled day, but it won’t be a wash‑out either. Expect a steady cloud cover, temperatures in the comfortable 60‑degree range, and a chance of a few low‑key thunderstorms in the afternoon. It’s the kind of day that reminds you why a good umbrella is a Portland must‑have.
