A winter weather advisory will be in effect for the Portland metro region from 3 a.m. to 10 a.m. on Monday, which means slick roads, traffic delays, and the possibility of snow for commuters on Monday morning.
Around the metro region and nearby areas, between half an inch and two inches of snow are forecast to fall on Monday afternoon and evening. For the slopes between 500 and 1,000 feet in elevation, several inches of snow is forecast.
However, while temperatures along the I-5 corridor south of Wilsonville are expected to be too warm for snow, the mountains will receive an abundance of it.
By the afternoon, temperatures should have risen sufficiently to allow the most, if not all, of the snow to melt away.
During the spring, there are days that feel more like summer and then there are days during the spring that feel more like winter. We are about to enter a period of chilly, wet weather that will make it appear as though we are traveling in the wrong direction.
It’s going to be cool out there on Sunday afternoon and evening, so wrap up warm. If you plan on spending any significant amount of time outside on Sunday, you should consider bringing a heavy jacket.
Forecasters predict that snow levels will drop to roughly 1,000 feet. Today’s rainfall totals are expected to reach approximately a quarter of an inch, with isolated pockets receiving a little more or a little less.
Mother Nature is giving us the chilly shoulder right now, and we are feeling it. In addition, by scrolling through the slideshow below, you can get a visual sense of the weather forecast: On Sunday, you’ll see a graphic titled “jet stream,” which will depict the severity of the wind aloft and what will be causing the unstable weather on the ground.
We have lots of strong wind aloft, which will help to maintain the snow coming from the mountains, as well as aid in the production of snow in the future. Winter advisories have been issued for the coast range and the Cascades due to the nature of the weather aloft and the cold air that has been brought in. Those will remain in effect until Monday.
