A weakening front from northern Canada will move across northeast Pacific Ocean during the day Friday and will push inland over the coasts of Oregon and Washington by the evening. The front will bring a slight downward trend in daytime highs and some morning clouds over the weekend.

Portland will see sunny skies Friday, and a high of about 83 degrees.

Did your weekend plans include getting outside to enjoy the Cathedral Park Jazz Fest or Sherwood’s Robin Hood Festival? It’s going to be perfect weather for festival-going this weekend. Portland will see highs in the upper 70s under partly sunny skies.

Maybe you’re heading to the coast. The National Weather Service says periods of light rain or drizzle are possible along the beaches and inland over the Coast Range from Friday night into Saturday morning. Rainfall amounts should only be a few hundredths of an inch, but beachgoers should take a jacket at least at the beginning of the weekend.

Portland will see cloudy morning skies Saturday, as stronger onshore flow develops due to the front. Skies will clear through the afternoon to partly sunny. Winds may pick up in the afternoon, especially near the Coast Range. The high will be pleasant, near 79 degrees.

Sunday will feel similar to Saturday with morning clouds, then afternoon clearing. The daytime high will reach about 78 degrees.

Extended forecasts are showing a warming trend coming to the region early next week with Monday and Tuesday both seeing highs back up into the mid 80s under sunny skies.

Parts of northeastern Oregon and southeastern Washington are under a fire weather watch Friday. Visit NWS Pendleton for more information.
