Good Morning. Southwest Washington and northwest Oregon will start Tuesday with rain and wind. A cold front is located to the north, bringing a weather system into British Columbia and western Washington. Most of the rain will fall this morning through the early afternoon, then taper off by late afternoon. West-facing slopes of the Coast and Cascade Ranges will see the most rain, with more than an inch of rain expected. Lowlands west of the Cascade Range will see only scattered showers. Temperatures will remain cool, with urban highs in the mid-60s F.
A ridge of high pressure will begin to move across the western U.S. starting tomorrow. It will move north to the Pacific Northwest later in the week. Temperatures will warm into the upper 70s to mid 80s tomorrow and Thursday, with the hottest temperatures expected on Friday. Temperatures along the I-5 corridor will reach the low 90s.
There is still a lot of uncertainty regarding the location of the ridge this weekend. The location of the ridge will determine whether temperatures will rise or fall and the chances of cloud cover. With the ridge centered on the eastern side of the Pacific Northwest, it is safe to assume temperatures will be in the low to mid 80s Fahrenheit Saturday through Monday. However, there are signs of it moving west again early next week, so temperatures around 90 F on Monday and Tuesday cannot be ruled out. Stay tuned for adjustments to the 7-day forecast.
Bottom line: warm, dry weather is ahead. Get ready for summer weather…
Have a great Tuesday!
