Dry and warm weather will persist over the next few days due to ongoing northwesterly flow. Numerical weather models indicate a weak shortwave moving across the forecast area on Wednesday, though it’s expected to bring little or no moisture. This afternoon, local winds through the Cascade gaps could become strong, reaching 25–35 mph, before easing to breezy conditions of 15–25 mph later in the evening.

Monday Sunshine

From tonight through Tuesday night, a trough currently situated over the area will shift eastward and exit the region. In its place, dry northwesterly flow will dominate the Pacific Northwest for most of the week. Temperatures on Monday will be near average, then increase to around 5 degrees above normal by Tuesday. Gusty northwest winds—particularly in and around Cascade gaps—will taper off overnight. After that, typical daytime breezes will persist in areas that usually experience more wind.
Fantastic Friday Ahead

Overnight satellite images show clear skies across the forecast area, with a ridge gradually building overhead today. Expect dry and warm conditions through the day, ahead of more active weather moving in by Saturday afternoon as a broad trough from the North Pacific approaches. While most of the system’s moisture is expected to remain to our north, the deep nature of the trough will lead to significantly tightening pressure gradients. This will result in a breezy day across the region.
Sunny & Gusty Thursday

Showers are moving out to the north of the forecast region as an upper-level disturbance passes through the Pacific Northwest. In its aftermath, high pressure is expected to rebuild over the area by Saturday. However, this transitional phase will bring an increase in wind speeds. Winds will diminish later in the evening as high pressure settles overhead and pressure gradients stabilize. This will be followed by another warming trend, with temperatures rising back into the 90s by Saturday.
Hot Temperatures Wednesday

A strong ridge of high pressure remains in place over the forecast region, leading to hot conditions today with temperatures reaching the upper 80s to low 90s in the lowlands. However, an upper-level southwest wave moving through later this afternoon into overnight may prevent temperatures from climbing even higher. This weather pattern is favorable for isolated showers and thunderstorms, especially over the Cascades and eastern slopes.
Temps Heating Up

Today through Thursday: A warm and dry period will set in across the forecast area through Wednesday as a strong high-pressure system builds over the Pacific Northwest. This will cause temperatures in the lowlands to rise, reaching into the 90s by Wednesday afternoon. By midweek, this ridge of high pressure will begin to weaken as a broad low-pressure system over the northern Pacific sends a southwesterly wave across the region.
