Portland’s Weather Mix: From Dry Beginnings to Light Snow in the Cascades

Portland starts Wednesday with a brief spell of clear skies, giving residents a momentary break from rain. But that calm is short‑lived. Satellite data shows an approaching front coming in from the eastern Pacific, set to bring a band of showers across the metro area. The National Weather Service warns that this front is moving fast, so expect rain to arrive quickly and last for most of the day. There is also a 10‑15 % chance that these showers could turn into thunderstorms, with brief periods of heavy rain. Hail, lightning and strong gusts are possible, so keep an eye on the forecast if you’re heading out. The wet spell will dominate Wednesday, with temperatures dropping to about 54 °F. Winds may pick up to around 25 mph at times, adding a chill factor. Afternoon snow levels are expected to lower, and heavier rainfall over the Cascades could produce 1‑4 inches of snow down to roughly 3, 000 ft. As the evening approaches and showers ease, snowfall will be uneven—some spots may still see a light coating while others dry out.Night temperatures will fall into the 30s, which could create frosty conditions early Thursday morning. By noon Thursday, skies will clear again and temperatures will climb back to about 57 °F. Friday promises a bright, warm day with highs near 65 °F and occasional gusty winds up to 20 mph. The weekend will see a shift in weather patterns. Saturday looks largely sunny, with temperatures around 64 °F, while Sunday will be mostly cloudy and could bring a slight chance of rain. The weekend’s high will settle near 61 °F. These changes highlight how quickly Portland’s weather can shift, reminding residents to stay prepared for sudden rain or light snow even when the day starts clear.
