Oregon – A calm, cool start is quickly giving way to a wetter pattern across Portland, where clouds are thickening and rain is already moving toward the metro. Early commutes remain mostly dry, but conditions will deteriorate fast by late morning.
According to the National Weather Service in Portland, rain becomes widespread today with a 100% chance of precipitation and totals between a tenth and a quarter inch. Highs will reach near 56°F, while winds may gust up to 25 mph, adding to reduced visibility on roads like I-5 and I-84.
Across the metro, Beaverton, Gresham, and Vancouver, Washington will see steady rainfall develop through the afternoon. Expect slick pavement and slower travel during peak commute hours. Plan extra time and keep headlights on as rain intensity increases.
By Wednesday, March 25, the system lingers with a 70% chance of rain and highs near 54°F. Conditions stay damp through the day, then shift again after sunset. Temperatures drop toward the mid-30s, allowing a brief rain-snow mix to develop overnight into early Thursday.
While accumulation is unlikely, slushy spots could form on bridges and elevated roads. This is the time of year when quick temperature drops can lead to slick conditions.
