Independence Day Weekend Outlook

Planning to go camping at the Coast or in the Cascades this weekend?  I’ve got your forecast covered.  Same thing if you plan to head east of the Cascades.


  • In general this 4th of July Weekend will be mild to slightly coolish (mainly Sunday) around the Pacific Northwest.
  • Who is guaranteed dry weather?  Anywhere south of Portland west of the Cascades and anywhere east of the Cascade crest & eastern Gorge.
  • Who MIGHT see a shower?  North Coast, mainly on Sunday AM.  Same thing from the metro area north into SW Washington…again on Sunday AM only.
  • Afternoon temperatures: 60s at Coast, 70s in valleys, and 80s east of the Cascades
  • Varying coverage of morning/midday clouds will continue west of the Cascades
  • Expect mainly sunny skies all 3 days anywhere east of the Cascade crest.  That also includes the Columbia River Gorge east of Bonneville Dam.

Here are the graphics showing a few more details for each area:




This pattern will continue through the entire week ahead.  High temperatures will remain at/below 80 degrees west of the Cascades.

    2 things .
    1 What is up with the fall colors happening so soon?
    And 2, what is up with Tue frost alert in central Oregon?

    This year has been interesting for Gardner’s growing their own foods .

    Been a peculiar afternoon here in the Boro. The clouds have been like waves, parting around noon to the west, banking up against the Cascades. Filling in a bit then clearing west of I 5. Can’t seem to make up its mind. Seems the central/northern Washington coast and southern Oregon coast lines are clearing faster than the northern Oregon coastal, and PDX to Salem metro areas with this weak frontal passage scenario. It sounds like it should be a good fireworks forecast even for the coast by tomorrow though! HAPPY ~ SAFE 4TH EVERYBODY!! And celebrate your independence from the EURO model!!!

    Seems I can’t post a link to the Alaska bear cam..

    Where’s the link for the 12 Day Outlook? Beautiful 7 Day BTW!

  5. This July is beginning to remind me of what Julys used to be like: variable unsettled conditions in the first part of the month before becoming mainly sunny and warm. (Of course, being further north than Portland, I often didn’t see the change til after the 4th.)

    • Paul D says:

      Portland usually gets its summer switch flipped on on the 5th, but this year it got flipped on and off numerous times before now. It’s been a weird year, so having cooler weather this week is part of this weird year.

      What’s next? Who knows, but make sure you’re buckled up for the ride!

    • Thanks, Paul! I should have said “the switch ” here historically is somewhere on average around the 12th-15th. Sometimes the difference is really dramatic; I recall one July (1998) where we had several cool cloudy showery days into the middle of the month. Then the next morning (I think it was the 16th) I woke up and noticed the living room windows were all fogged up – on the inside!

    Mark what is your thoughts on the NWS updating the temps every 5 min. Seems as though something is happening, as I notice Salem will jump around like 3 degrees on a day like today in 5 min, which I think is a false reading, but the high numbers are being recorded as the official high temps for the day. Seems very fishy to me.

  7. I like bone dry upper 80’s and 90’s but I like green too. Sunny and 78 is not too bad. Enjoy the 4th!

  8. We had a few sprinkles here yesterday morning, and today is showing another mix of sun and cloud. Nothing wrong with that- I prefer this over 90 degree temperatures.

  9. JERAT416 says:

    I would like a little warmer but not over 85, mainly since i have 2 floating trips planned. However, with the high sun angle, when it’s sunny and upper 70’s, it’s still comfortable. I’ll take this over 90’s anytime. Have a great 4th everyone!

    Mark I saw that the jet stream at the equator is mixing from the northern latitude will the earth be cooling due to cooler air mixing with the warm equator air. saw it on you tube

  11. WEATHERDAN says:

    Latest 16 day outlook shows no heat, but no rain either. I would expect 78-86 with just some AM Clouds. Warmer on the days with less clouds. Sunny today with a few high clouds. 74 at 1:00 PM going to 83. This is for the Central and South Valley. For PDX I would expect 74-82 due to more morning clouds generally. Peace.

    • Paul D says:

      Look out! Somebody snuck some raindrops in on Sunday morning on the 7-day forecast!

    • Mike near Clackamas Town Center says:

      I’m ok with the current pattern of morning clouds and afternoon sunshine. Keeping the temps from soaring past 90.

  12. Dizzyland says:

    The last week was absolutely beautiful even for Oregon with deep mountain blue skies like your in Lake Tahoe.

    Today the skies are totally yucked out and the sun is almost blotted out with a more stagnant feeling.

  13. muxpux (Longview) says:

    This weather is “perfect” except were trying to fill the boat for the 4th. Hard to get people to wanna get out on the water when it’s 75 and partly cloudy

    • Dizzyland says:

      If you call the sun being blotted out and little to no wind perfect well one man’s garbage is another man’s treasure.

      All of last week was what one could describe perfect with Tahoe blue skies in every which way and the mountains were the most clear I have ever seen except on rare occasions.

    • Paul D says:

      75 and partly cloudy sounds like awesome boating weather! It ain’t hot, it ain’t cold, it ain’t wet.

  14. Late last night I was comparing my mean temperature for the last week of June with the last days of June 2015 for the same time period. Big difference! This year I was 9.9F cooler- and even with that we’re still slightly warmer than normal.

  15. Andrew says:

    Random question of the day… Does anyone know what happened to Jim Donovan on KGW? He hasn’t been on since January I think, yet his bio is still up on Was on weekend mornings then boom, nothing.

  16. MJ says:

    My reply on the prior post must have got caught on moderation. I was trying to say how certain ppl should post their own outlooks for the coming week if they think they can do better than Dan. Have seen quite a bit of smack, talk but never see their own outlooks.

  17. Boydo3 N. Albany says:

    What a great forecast compared to last year! More like the weather we expect this time of year.
