June Weather Next 7 Days: 80 Degrees For Some!

11pm Thursday

Today was incredible wasn’t it?  It sure is true that stretches of gloomy/cool weather make us appreciate the sunshine.  I worked a half day today which meant about 5 hours in the sunshine.

Todays Observed Highs OrWa 2017

I think I burned my face just a bit.  That is very possible from now through early September; the highest sun angle of the year is only 2 months away.  I think most people are surprised the sun is just as strong as late August.  In fact the sun angle is the same today as it was during the solar eclipse last year.

Just a quick note to let you know we are in a pretty stable “early summer” weather pattern for the next week.  The weak late April jet stream has shifted a bit to the north and seems to stay up there for the next week.  One weak system moves by to our north Friday night, but after that time the atmosphere warms up quite a bit.

The result is a switch of cool & wet to warm and dry.  A typical high temperature in June is the mid 70s and that’s where we are headed much of next work week.

Headlines Spring Summer

Could we hit 80 degrees?  Yes, I think that’s likely if current model runs hold.  As of now they are all showing a perfect setup for 80+ weather.

A) A classic “thermal trough” or low pressure west of the Cascades or along the Coast Monday-Wednesday.  That gives us easterly wind through the Gorge and over the Cascades.  A “downsloping” wind warms us nicely in this warm half of the year

B) Mostly sunny skies Monday-Wednesday

C) 850mb temps are forecast in the +12 to +15 range over Salem.  That’s the temperature in celsius around 5,000′ elevation.  It doesn’t get too much warmer than that in April; +18 is the highest from 1992-2009.

Past setups with these 3 ingredients in late April have pushed Portland metro high temps up to 80-85 degrees.  Get ready for summer weather for a few days.

A week from now you’ll need to water your potted plants, although there’s still plenty of ground moisture so you can skip watering the lawn/garden.

Enjoy the weekend!

    Alright, hoping for some weather action on Friday after this heat wave.

  2. W7ENK says:

    What a beautiful day! Blue sky, sunshine, 65 degrees, and it’s snowing!


  3. K says:

    Though I don’t think a small heat wave is terribly exciting, let’s hope the weather stays interesting.

      Small heat waves can bring small thunderstorm outbreaks…

      A la 4/20 in 2016.

      • K says:

        Let’s hope so! I haven’t checked any models in the past few days. Is there a chance that we could get a thunderstorm outbreak?

        • Ken in Wood Village says:

          I still keep seeing something trying to get started on Friday. If you look at the GFS, you’ll see something starting just south of us and then start moving north. That is normally a classic way to get thunderstorms. I also see some heavy moisture hitting around Portland too.

          I haven’t looked to see what the NWS says but they had said something about the possibility of thunderstorms on Friday (that’s if it the pattern stays the same) 🙂

        • Ken in Wood Village says:

          One thing I am looking forward to is going up to Crown Point. Since the East wind is starting to blow, it would be fun to feel it…lol. I either will be up there tomorrow or Tuesday. Just need to find out when the wind is the strongest 🙂

    Very interesting about the suns’ angle being the same as in August at noon time. It shows how much the winter cold still affects the suns’ warming ability with high temps not able to get above 80 or so. Something to think about…. is it the northern hemisphere ground temperatures that that help hold down the highs then?

  5. Roland Derksen says:

    Looks like we’ve turned “the corner”: I don’t see 80’s in my location, but those 70+ temperatures after Monday will feel good. Did I experience the last rainfall of the month yesterday evening?

  6. Ken in Wood Village says:

    Just looking at some of the models. It looks like we could see some interesting weather the end of next week. It’s way out there but just thought I would point it out. I’m hoping with the warm weather it could produce some good thunderstorms 🙂

    Wow! I think I’ll be buying tomato plants to plant today! Don’t see why not?

  8. Anonymous says:

    Damn, was really hoping this early heat was NOT due to East wind!! Figured it would be the case, but still, always a dissapointment

  9. runrain says:

    When can tomatoes go in the garden? First week of May?

    • W7ENK says:

      Now. I meant to get some and put them in today, but I ran out of time. It’ll have to be next weekend for me.

  10. W7ENK says:

    It’s about freakin’ time!!

  11. Joshua Downtown PDX says:

    The models are trending warmer for next Wednesday/Thursday. Mid to upper 80s???

  12. lurkingsince'14 says:

    BRING IT ON! 🙂

    Vampires beware. Here comes the sun.

  14. Paul D says:

    WOW! That weather pendulum is really swinging! Possibility of 80? Why can’t we just hit 70 and call it good.

    • JERAT416 says:

      Yeah, I don’t think 80 is necessary, but it’s still a nice treat compared to a few weeks of cool and wet. Will there be any snow left in the mountains a week from now is my question

  15. Joshua Downtown PDX says:

    It looks like a quick cooldown by next weekend. Thank Moses. We don’t need summer to start in April yet again.
