Weather Podcast: Brian and Mark

Brian Macmillan has posted our 2nd podcast here:

In this episode, the guys talk to storm chaser, Meteorologist Greg Nordstrom, about this week’s tornadoes in the south.  Also, this month’s extreme weather records and kids’ questions.  Plus the latest marriage plans in the weather center.

    @ W7ENK:

    If I’m thinking of the right time… That would be July 8 last year. I got these instability parameters uploaded on Tinypic. There actually were very low LI numbers but something else must have capped storms from developing other than moisture.

    SFC CAPE (2000 – 3000 J/kg)

    MLCAPE (2500+ J/kg)

    MUCAPE (I think 3000+ J/kg)

    Lifted Index (-5 at PDX, -7 at SLE)

    A very strong cap was obviously present, so all of this potential for what could have ended up to be an epic “Midwest type outbreak” was completely wasted.

    • Timmy_Supercell (Klamath Falls @ 4200') says:

      WHOA! I didnt know I had this one uploaded:

      SB Lifted Index @ 2300 UTC – July 8, 2010

      Look at that -11 reading to the SW of Bend!!!

    • Benjamin (West Salem) says:

      what factors determine lifted indexes, and MU CAPE?

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

    Okay so Chuck Norris played baseball in Knoxville, TN – did a little wrestling in Birmingham, Al – and next hed probably go surfing along the west coast. Oh boy, would we really wanna get into that topic…. 🙂

    What happened to today’s rain? NWS Portland this morning said 100 percent chance of rain today, with between a tenth and a quarter inch. We got zilch, and quite a bit of sun. I don’t know enough to understand how a same-day forecast can miss so badly. Anybody have insights?

    18Z GFS – Warmest run of 2011 so far. 850mb temps soar to 15C for about 3 days end of next week which could provide a day or two in the (dare i say) 80’s 🙂

    of course the 00z may just snatch all this away tho.

    • W7ENK says:

      I’d be more apt to believe this it weren’t at least 12 degrees off with today’s high of significantly warmer than 49 degrees, but since this run was so grossly inaccurate in the immediate range, I’m not putting much faith in any of this… especially NOT that 84 degrees two weeks out.

  5. W7ENK says:

    I’m hearing rumors of power out all over the area, and numbers climbing? Only light breezes here in Downtown – less that 15 mph all day – and my sister says there hasn’t been any wind in Milwaukie or Sellwood today either, so I can’t imagine it has to do with anything wind related…

    PGE site says “Equipment Failure”, but that could mean almost anything.

    • Runrain says:

      See my post below. Pretty strong winds in Happy Valley. The kind you can SEE too!!

    • Yeah, it’s a little quieter now, but pretty consistently gusty winds out in Tigard, too. A little surprised they’d cause problems, but I s’pose…

    • Rob "Wrath" S.E. Portland says:

      I checked awhile ago and there were about 10,000 people without power. Wind related? Maybe. Gusts were 28-35mph.

      Oh and if we’re to see any convection it will be over the next 3 hours. Very slim chance. Cold pool aloft is overhead with 500mb temps -27c to -29c. SBCAPE 250J/kg, no CAP, MUCAPE 100J/kg. LI however is +2, mid-level lapse rates are only 6.5C/km, so doesn’t look too promising.

    • W7ENK says:

      +2 LI kinda kills it, no matter how good the rest of the conditions are… I guess we just don’t have all the ingredients in place… yet again.

      Kinda like last summer, I don’t remember the date, but I remember we has SBCAPE something like 4000J/kg, but absolutely no moisture present at any level… talk about a wasted opportunity. 😥

    • Mark Nelsen says:

      There are only 200 without power, and none within 30 miles of Portland.

  6. muxpux says:

    just had a heck of a downpour roll through Longview. not that impressive on radar, unless you zoom in on the “wundermap”

  7. Kyle From Silverton says:

    What was that year where the coast had lots of CG lightning over the water for hours and hours in which the storms literally fell apart as soon as they tried to cross the valleys over here?

    • Austin(Cornelius) says:

      Year before last. We were camping in it. The thunder was rather quiet in the realy hours. But lots of lightning. By the time we got home it was sunny.

  8. Runrain says:

    So, looks like May is probably going to have a continuance of the cool, damp weather. And then, of course, follows our typical Juneuary. In brief: Farmers markets this year equals CANCELLED! Hope California will share some of their fruits and vegetables!

    Strongest winds I’ve seen in some time out there right now. Oops! Now Jesse is going to post that you can’t actually SEE the wind…

  9. Rob "Wrath" S.E. Portland says:

    Very weak elevated instability is trying to develop around 100J/kg…

    • Rob "Wrath" S.E. Portland says:

      Oh and breezy south winds right now 24-28mph.

    • Kyle From Silverton says:

      Is there actually a difference between 100j/kg and 200 j/kg besides the numbers?

    • W7ENK says:

      I would say probably on order of about 200% available energy … just a guess. 😛

    • Kyle From Silverton says:

      Thru shifting thru posts I am trying to figure out what is the best conditions for T-storms as sometimes a little gives a lot and a lot gives a little.

      Remeber that one year (I think last year or the year before) where the coast got lots of T-storms with numerious CG lightning strikes which fell apart when they came to the valley?

  10. pappoose in scappoose says:

    Sun and quite a bit of blue presently.

  11. Rob "Wrath" S.E. Portland says:

    Currently tracking colder air aloft moving inland. Mesoanalysis shows 500mb -28c just west of Astoria. Not the coldest pool of air by any means, but if things work out right I suppose some hail or isolated lighting strikes are possible this afternoon and early evening.

  12. W7ENK says:

    Hmmm… I think I thought I might’a perhaps sort’a kind’a maybe just heard some thunder over Downtown???

    I’m that positive about it… 😉

    Nothing of significance on the lightning map… yet.

    • Rob "Wrath" S.E. Portland says:

      Nah, nothing on radar but light showers at the moment.

    • W7ENK says:

      I saw quite a bit of ugly mammatus roiling over Downtown about 9 o’clock this morning, and some really dark clouds looking to the South.

  13. April 2011 in Battle Ground

    Highest High: 69.0, 23rd
    Lowest Low: 28.1, 8th
    Highest Wind: W 31, 2nd
    Most Precip: 0.99″, 4th

    Total Precip: 5.90″ (my first year of record at this station, but I’m sure (and I hope) this will stay the #1 spot for some time!)

    Avg High: 53.7 (-7.7)
    Avg Low: 36.9 (-3.8)
    Mean: 45.3 (-5.8)

    The mean was a whopping 0.2 degrees warmer than March.

    Although the average high was 53.7, many of the days saw very brief warm temps.

    Notables: Trace snow on the 19th

  14. …I’m not sure that i like the visual that comes to mind with “working out with the weather”…. 🙂

    • W7ENK says:

      Brings to mind perhaps Chuck Norris wrestling with an EF4 tornado, snapping it off from the base of it’s wall cloud, putting it in a choke hold and pinning it down on the plains, holding it there until it taps out…


    • Mike (Orchards 255') says:


  15. Mark Nelsen says:

    No, Brian gets top billing since he puts it all together. I just show up and talk.

  16. W7ENK says:

    So, not the other “Mark and Brian”? 😆
