82 Degree High Today; Summery T’Storms in Eastern Oregon Tonight

Portland Airport officially hit 82 today, same with the forecast office in Parkrose and the Downtown Portland station too.  Looks like all other areas west of the Cascades (at least official stations) were in the 78-82 degree range.  Quite impressive for April 22nd.

If you want to check the numbers yourself, here they are:


As I was outside enjoying the last few minutes of daylight just now, I noticed bright orange tops of clouds just over the horizon to the SE.  Sure enough, thunderstorms in progress over the Warm Springs Reservation and heading towards Maupin/Pine Grove areas:

Speaking of thunder, we have a decent chance of some thunder and lightning action at some point late tomorrow, at least AFTER 5pm. I’ll post about that tomorrow afternoon, but it should suffice to say that anywhere west of the Cascades could see a late day or evening/night thunderstorm tomorrow. Nothing before that time.  Your Monday still looks very sunny and warm, similar to today.

A good thunderstorm outbreak would wrap up a very nice 3 day warm spell!

    SREF – 09z run

    Willamette Valley

    Surface Lifted Index: -5 (-6 around Eugene)
    SBCAPE: 1000 – 1250J/kg
    MUCAPE: 1250 – 1500J/kg

    Effective Bulk Shear: 40-50 kts. (favors organized, rotating storms)
    2m Dew Point: 55-60 (very moist)

    Supercell Composite Parameter: 3 (6 south of Eugene)


    This instability model does show a little less CAPE at the surface levels… but based on many other factors, it really should not matter at this point. With a fairly steep, sheared atmosphere where there is little to no capping, plus not to mention the strong Lifted Indexes…. storms will have no problem developing over the cascades and later in parts of the Willamette Valley. Timing is still not certain; but many of us could have an exciting day ahead.

    Red sky in morning, sailor says… “Looks like today could be a very active weather day!”


    • AdamInAumsville says:

      Lots of altocumulus out there this morning. Good sign for later!

    • W7ENK says:

      Yep, the sky is a whole Smörgåsbord of convective-type clouds this morning! It doesn’t hurt that I woke up to 56 degrees, and that we had nocturnal convection west of the Cascades last night… and it’s only April!

      Possible Spring 1993 redux in the making… 😀

      Oh, and FWIW, this photo (above) was quite literally the first thing to hit my retinas when I awoke this morning.

    Looks good for thunderstorms this afternoon and evening

    • paulbeugene says:

      But I would comment that there will be a SW marine push that will progress through Eugene and work N toward PDX. In my experience this has favored areas north of Salem, with south valley being shut out by marine influx as convection builds over central OR Cascades and then works its way N and NW.
      Could maybe see 5 cent hail somewhere near PDX.

    Woke up to lighting and hearing thunder in the distance. Sounds to be north/west of me ….to BattleGround.

  7. frederm says:

    anyone seeing the flashes tonight? looks to be from the north west. no thunder. must be far away.

    • bgb41 says:

      Big bolts of lightning right over my house with heavy rain at 140am (Battle Ground Lake) …Lasted about 10 mins

  8. Ok, ready for winter again! It’s too freakin’ hot to sleep!!!!

  9. boydo3 N Albany says:

    Pats of NE are going to see their biggest snowfall of the year. After a record warm winter. Go figure….

    • David B. says:

      It’s hardly the first time such things have happened. I remember one year in junior high school in the southern Rockies when the whole winter was pretty much a bust for snow, and then there was a huge dump on May 2nd, even had to let the schools out early because the snow was falling so hard the plows couldn’t keep up with it. (This was back in the late ’70s.)

      It gave me the last laugh on the newcomer neighbor kid who thought I was nuts when I said it looked like snow today that morning at the bus stop.

  10. boydo3 N Albany says:

    Brian, how’s that temp forecast comp. going? 🙂

  11. karlbonner1982 says:

    I caught a few thunder flashes south of The Dalles around 8:30pm. Might have been from that Maupin cell?

    Also notice that the dewpoint at DLS has crept up to a sticky 55F. After a high of 85-87 (depending on neighborhood), it REALLY feels like summertime outside!!!!

  12. W7ENK says:

    Decent cell moving NE through the Tygh Valley, skirting the back side of Mt. Hood…

    It’s putting on quite the show, lightning being seen to the East from as far out as Beaverton!

    • Kassie97222 says:

      Are there any sky cam links or something that we can see the thunderstorms on the computer?

    • W7ENK says:

      Oops, I didn’t see this before… sorry.

      And, I’m not sure if any of the cams pointed out East from the city would pick it up?

  13. Dave in SW PDX (235') says:

    Awesome weather for Earth Day! My high was 82.7°; nice to see the official WX observations confirm my max temp reading, as this is the first spring/summer season with my Davis VP2. I’m ready for more 80° weather & possible t-storms tomorrow.

    • oregonalex says:

      🙂 I got 82.7° high on my Davis VP2 in Rock Creek too.

    • oregonalex (Rock Creek, 240 ft) says:

      Of course, this does not mean much beyond being a fun coincidence. The temperature sensor has +-1°F accuracy by itself. On top of it, there is solar radiation error @ noon +4°F for the standard shield or +0.6F for the fan aspirated shield (I do have the fan aspirated one).

      Still, gives you a warm and fuzzy feeling when numbers match…

  14. weathercrazy82 says:

    81.5 up here today. Nice to see the towering clouds this afternoon and even a few flashes of lightning!

  15. Timmy_Supercell (Klamath Falls @ 4200') says:

    SREF instability parameters have been consistently exceeding that of June 4th 2009, even. This all better not go to waste.

  16. Timmy_Supercell (Klamath Falls @ 4200') says:

    High / Low today in Klamath Falls.

    81F / 39F

    First 80 of the year!

  17. Kassie97222 says:

    Yay for possible thunderstorm action, hopefully they break through the cursed milwaukie dome!

    • W7ENK says:

      Right? I might have to leave work early and break out my camera!!

    • Kassie97222 says:

      Im going to take pictures to! If it actually gets active enough I might record some video! I think I am getting too happy over a “possible” storm…

  18. W7ENK says:

    ‎85.1F at my station today.


    Here’s a photo of my cherry trees today, in full bloom!

    When the breeze would pick up, the white petals were falling down like snowflakes. It was kinda surreal…

  19. Timmy_Supercell (Klamath Falls @ 4200') says:


    Seriously, this is serious 🙂

      Where’s the ‘Like’ button, Mark?

    • Gabriel says:

      So does this mean the valley will get hammered by thunderstorms Tuesday afternoon

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      Tuesday, I am not totally sure about any storms in the Valleys. But today, conditions are more than prime for a handle of strong cells out and about…. some will be severe.

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      *handful of strong cells*

      Darn typo…

    • gabriel says:

      yeah sorry timmy supercell i meant monday not tuesday but any chances one of those storms could impact salem today cause Im looking forward to seeing some today hopefully i dont mind thunderstorms but i dont like tornadoes.

  20. JJ97222 says:

    What a perfect couple of days now this is spring weather! Now a few thunder storms than lets do it again more 70s and 80s. This was great, everyone I spoke with were very happy to see this happen after the past two years. Got a lot work in the yard done that I did not get to till June last year.

  21. Sandman, Aloha 300' says:

    Yeh! Nice weather!

  22. vernonia1 says:

    thunder would indeed be nice 🙂 Today was great!

  23. Andrew (Near Silver Falls 1600') says:

    Got up to 70.5 here today. Warmest day of the spring. Low this morning was 45.
