Friday is the ideal day to engage in outdoor activities.
Friday will be a largely dry day in Portland, with a few sun breaks just for good measure. Although it should be light and showery, rain is expected during the afternoon. It will get as high as fifty-two degrees. It sounds good.
However, when the clouds move in later Friday, National Weather Service forecasters are keeping an eye on a powerful low pressure system that is heading east from the Pacific Ocean. This system is expected to deliver two or three frontal systems to the area starting on Saturday and continuing into the beginning of next week.
Later Friday, the weather service predicts that light rain will mostly affect the northwest Oregon coast and southwest Washington. It’s possible that Portland won’t get much rain during the Friday evening commute.
Given that the first front is predicted to arrive in the early afternoon, Portland should begin Saturday largely dry. Residents will have pleasant temperatures in addition to the rain, as Saturday’s high is predicted to be around 59 degrees. They’ll sense the wind, too. Throughout the day, southerly winds will intensify, reaching valleys at 25 to 30 mph. Beaches along the coast will experience gusts of 45 to 50 miles per hour.
Rainfall is expected from 4 a.m. on Saturday till 4 a.m. In the valley lowlands, Sunday’s forecast is for half an inch to an inch, with a 30–50% probability of more than an inch. Up to two inches might accumulate on the coast.
As the second front in the series advances onshore, rain rates will increase over the course of Saturday and Sunday. Strong precipitation and persistent gusty winds are predicted on Sunday. The high will remain close to 60 degrees.
The weather service warns residents of lowland and urban floods, standing water in areas with poor drainage, and localized ponding water on highways and freeways. Additionally, steep topography and landslide-prone places are more likely to experience landslides.
The Wilson and Grays rivers along the coast are among the Oregon rivers that might reach minor flood stage on Sunday.
Sunday is expected to bring another inch of rain to Portland and the Willamette Valley, with a 10–20% possibility of more than 1.5 inches.
Furthermore, it doesn’t end there. According to extended predictions, Monday and probably Tuesday of next week will see further widespread rain. The areas of western Oregon that receive the most rain on Monday will depend on where the next front forms before moving inland. Stay tuned for more information as the weekend goes on.
Go away, rain, rain! The figure below shows the possible quantities of precipitation from 2/22 at 4 AM PST to 2/25 at 4 AM PST. These precipitation totals cover a 72-hour period. Most places will continue to see temperatures above freezing.PftipjXydu #WAWX#ORWXpic.twitter.com
