Flying Through Thunderstorms

This has absolutely NOTHING to do with our weather, but I found it fascinating reading.  On another WordPress Blog, an airline pilot explains how they fly through squall lines.  Easier than I thought it was.  The link is below the picture.  What a picture too!

    SPC Day2 Convective Outlook
    Valid: 9/7

    They do have our area under a ‘General Risk’ for non-Severe Thunderstorms.

    15z SREF
    Valid: 9/7

    SBCAPE: 500J/kg
    MLCAPE: 250-500J/kg
    MUCAPE: 500-750J/kg

    PWAT: .88″ – 1.05″

    Wind Shear
    Effective Bulk Shear: 20-30kts
    0-6km Bulk Shear: 35-50kts

    I’ll have to take a look at the 12z sounding tomorrow(Around 7 AM) and primarily check the Convective Temp and Lapse Rates. Then throughout the day monitor the Mesoanalysis updates to see if conditions are becoming unstable or favorable.

  5. NWS mentions a slight chance of t-storms tomorrow? Seeing no discussion here about it, I have to assume “slight” means nearly non-existent!

    • Rob "Wrath" S.E. Portland says:

      Oh… Well I have been busy the past 4 hours helping my Dad put up a new light fixture(FUN)….

      On the 12z WRF I did notice some instability and a good 500mb cold pool right overhead around -20c to -22c…. I think it is possible, Keeg.

    • Rob "Wrath" S.E. Portland says:

      Let me check a few more things……………

    • Thanks, Rob – definitely always look forward to the analysis from you and others here…hope there’s something worth mentioning…

    • Rob "Wrath" S.E. Portland says:

      No problem and thanks also. I really enjoy providing analysis.

    A pretty good photo of Mt. Hood’s lenticular cloud on Friday.

  7. PaulB/Eugene says:

    Got back from Europe today. Went over Gerlos Pass elev 4920′ in Austrian Alps. They had a few inches snow on the ground when I drove over it last week, leftover from previous day’s early season snowfall. Not much warmer here I guess. Hopefully this winter goes nuts and clogs the blog.

    • Rob "Wrath" S.E. Portland says:

      Welcome back, Paul. I have always wanted to go the Alps. Oh yeah I bet we see some real major events and I think the highlight might be a big wind storm.

    Burns and Baker both 25 last night.

  9. Derek Hodges says:

    41 here in Utah, so coldest night of the year here too. I don’t know if anybody has posted about it but the la nina continues to rapidly strengthen. It could be the strongest ever if current trends continue.

    • Richard (East Portland) says:

      Derek, what do you think the possibilities are for a record la nina, and what will be the resulting effects for here in Portland and in Utah?


    • Rob "Wrath" S.E. Portland says:

      Hey, Derek…. It was 43.7 this morning and yep the indicies are lining up rather incredibly given the short duration things have turned over the past 6 months. Those SSTs are insane I mean at this rate they might have to add another shade or 2 on the negative departure colors 😆

    • Scott in West Jordan, Ut. says:

      Derek- I live here in SLC as well. Moved here a year ago from Corvallis. I had lived in Welches, Or. prior to that for about 10 years. Yes it was a great day today worked all day but left at 730am and it was crisp and very fall-like. you know where headed that way, the news had Ely, Nv. 33 tonight but 88 for a high tommorow, quite the daily range. I post on the blog very infrequently but certianly “peak” all the time. I’m hoping like everyone else that yes this La Nina is epic. I have done some research and it appears La ninas can be very fruitful for us here on the Northern Wasatch, Last La Nina proved to be better than avg snow & cold. Here’s definitly to hoping. I wish the same for our Oregonians La Nina is a good thing!! By the way wish OSU could have pulled that game off in Texas. What a great game tonight. Boise comes up huge on the big stage. Gotta Love Football season.

    First teens of the season in South Central Oregon this morning.

    19 degrees at KLAMATH NWR

  11. Mike (Orchards 255') says:

    Low this am of 45.

  12. Dang! Almost made it into the 30’s. Low of 40 this morning.

  13. Kyle says:

    49.8F for the first time of the “fall” year. Good night.

    This will be our first “heater” night for a brief time.

  14. Battle Ground Brian says:

    Midnight Temps

    29 at Crazyman Flat (low near 20 tonight there)
    41 at Timber Junction
    43 at Yacolt

    Clear Skies so I am wondering if it gets under 20 in parts of South-Central Oregon tonight. That would be a first for Fall 2010. I think mid 30’s are not out of the question in coldest spots of the Portland CWA where the least amount of AM Stratus occurs.

  15. W7ENK says:

    Oops, this should have gone here… I wasn’t paying attention. 😳

    It’s chilly out there tonight! I can *almost* see my breath… It’s kind of refreshing, actually. Fall is definitely in the air. It won’t be too long before we start seeing the evening/morning fog in the Valley and Metro area. Actually, I love those foggy fall evenings.

    [Milwaukie] 9/4/2010
    69.6°F High ◄▬ on par with PDX
    51.8°F Low ◄▬ right now
    SW 10.1 mph at 12:29p

    • Mike (Orchards 255') says:

      Yeah, its feelin’ like Fall now…

      52°…Should be in the 40’s by daybreak.

    • pgiorgio says:

      Funny you should say Fall is in the air. Tonight was the first night I thought the same thing here in Michigan.

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

    I am already down to 51.9. Widespread 40’s seems very likely at this point. It will be refreshing and crisp at 6 AM for my morning walk.

  17. Kyle says:

    *sighs* 57.2F here.

    I wouldn’t be surprised if no one even responds due to hating unusual cold so much.

    I wonder how busy this blog would’ve likely been during the October 2002 cold snap.

  18. Kyle says:

    So what’s the weather going to be?

    I am surprised no body gets excited when we have cold summer/fall nights though I guess it was only me and Snow Whizard that really got fired up on the mention of cold.

    Too bad no one else shares the enthusiasim 😦

    It’s amazing in the winter this place is buzzing with 100+ posts per day in a NW airmass but now there is like only Brian and Rob.

    This is Rob’s weather blog today.

    • Jesse-Orchards says:

      I like cold Summer and Fall nights. 🙂

      Tonight should see widepspread 40s. Maybe even PDX (finally)

    • Sifton says:

      Finally?? I’m guessing you might be a + size gentleman therefore not a fan of the heat, am I right Jess?

    • …Sifton,i find that remark very offensive, inflammatory, and totally needless in a civilized society

    • Rob "Wrath" S.E. Portland says:

      Larry, why? He pokes fun of others, insults others (Jokingly?) sooo. I know exactly what this is about and why.

      “What comes around, goes around.”

      All I am going to say.

    • Rob, i know…however i just feel that posts like that are stooping to the same level of behavior that makes me cringe, no matter who it comes from…i’m just tired of reading personally insulting remarks, when i’d much more rather be reading some kind of weather remark, fact, observation, or creative use of weather in conversation, etc…

    • Rob "Wrath" S.E. Portland says:

      Yeah that is true… We will only go backwards if not, not to mention others may get involved like a cruddy snowball effect.

      NICE day outside!

      Here we go again!

    Very nice day. Started out sunny, became partly cloudy by mid day and then ended up with clear skies by sunset.

  21. WeathermanRob says:

    Good read… While in school I learned a little bit about the ones they have on planes. Leaps better than the old days, but they are not without fault. They are very small systems being on the plane. They can run into issues of the beam attenuating and therefore missing some cells. In the past there have been a few accidents where pilots flew into a decent storm because the radar couldn’t see it.

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

    Wow amazing pic.

    Well it is getting to be that time of year where I start to look at the WV Loop more often, primarily the 28km Pacific Wide view and 16km. I also look for progressively stronger low pressure areas near 170 E – 170 W.

    The 18z Pacific Surface Analysis shows that a fairly potent low near the date line is projected to deepen to 978mb and move north towards the Bering Sea.

    It won’t be too much longer until we see such systems into the Gulf of Alaska as the jet stream intensifies.

    • Boydo3 500' North Albany says:

      I can wait. It seems like we got a very short summer, so if the stormy weather holds off till late October I would be just fine. But the models don’t look very nice I will have to admit.

    • Boydo3 500' North Albany says:

      BTW, did you ever do any good fishing? I just got back from a couple days on the south coast fishing the Umpqua for salmon. My wife got a beautiful 23lb chinook which we shared with a bunch of people last nite.

    • Rob "Wrath" S.E. Portland says:

      We did okay in July, but awful after wards. Cascades Lakes seem to really slow down in August although evenings can still be pretty good. The Fish simply seek deeper waters and aren’t as hungry. The best time is right after the ice melts in May through early July.

    • Rob "Wrath" S.E. Portland says:

      Oh and nice one 23lbs.. A bit envious of your dinner too! Salmon is super tasty.

  23. W7ENK says:

    Wow, that’s and awesome photo!

  24. Woke up to clear skies and a low of 45° this morning, now partly cloudy and 64°.

  25. HIO Phil (Punxsutawney) elevation 189' says:

    Cool pic Mark!

    One of my uncles was a pilot (small planes) before the advent of plane based radar. He is now too old to fly. Back then you had to rely on tower reports, and your own eyes as well as your knowledge of how weather works to avoid trouble. He gave me a really nice book that taught pilots how weather systems worked, how to read clouds, and how to avoid or navigate various types of weather conditions.

    Many years ago when I used to fly on corporate jets, I was talking to the pilots and pointed out some t-storms off to our right somewhere over the mid west. They took it as concern and replied “Don’t worry we won’t be going anywhere near that.” I said, “Oh I wouldn’t mind getting closer. Just avoid the hail shafts”. At which point I suspect they thought I was crazy. 🙂

    Only 52.1 for a low here overnight. Low clouds and onshore flow kept us warm.

  26. Glen says:

    Wow. Thanks for the post on that, Mark. Awesome read too. I lived in KC as a young kid and saw a large tornado first hand, not to mention many summer t-storms. To this day I marvel at how planes work around weather systems.

  27. MasterNate says:

    WOO HOO!!

    • MasterNate says:

      Gotta say I love this cool fall weather. Great for working outside, cutting firewood, working in the field. Getting real excited in anticipation of a wild winter. Hopefully!
