PORTLAND – The morning air feels heavy and damp across the Willamette Valley, and the steady rhythm of rainfall echoes through downtown Portland. Flashes of lightning briefly cut through the gray as scattered rumbles of thunder roll east toward the Cascades — a classic fall storm setting the tone for a soaked Sunday.
The National Weather Service in Portland reports widespread showers and a few isolated thunderstorms through this afternoon, with gusts reaching 25 mph along I-5. Commuters should prepare for ponding on roads and reduced visibility during heavier downpours. A secondary wave of light rain lingers into tonight before skies begin to calm by early Monday.
By Monday afternoon, drier air filters in, and partial sunshine returns across northwest Oregon. Highs hover near the mid-50s with light southerly breezes — a welcome break after a soggy weekend. Tuesday brings a brighter, milder setup, with highs climbing into the upper 50s to near 60°F. That trend continues midweek, creating perfect conditions for outdoor cleanup or early Halloween decorating.
Models hint at another round of light rain by late Thursday or Friday, though it should remain brief and scattered. Trick-or-Treat weather on Friday currently looks dry and mild, ideal for families heading out around sunset.
To be fair, this respite may not last long. Cooler air patterns forming over the Gulf of Alaska could usher in a chilly November with more rain and mountain snow by the first weekend of next month.
