Chilly Evening!

Snapshot I keep forgetting to mention this on the blog.  In case you didn't know it, the meteorologists here at KPTV do school visits each week.  We take a 45 minute presentation to just about anywhere wihin about 30 miles of downtown Portland.  OCCASIONALLY a bit farther away.  I'm planning a "Valley Day" and a "Lower Columbia" day this year.  I'll try to hit 4 schools in those areas in just one day.

Moving on to the weather…it's getting chilly out there quickly!  I notice PDX is running 14 degrees cooler this evening.  Also some cloud cover sliding south out of S.W. Washington.  I'm not too concerned about either one, although hopefully my low temp forecasts aren't too high.  This is from a shortwave trough sliding south out of Alberta and into Western Montana.  This heads off to the S.E. tomorrow, with surface high pressure building in behind it.  That turns our flow back to offshore/easterly by tomorrow evening and Thursday.  Then another wave shifts flow back to onshore Friday and Saturday.  A bit of a see-saw with the pressure gradients for sure.

Models are very consistent on a much stronger and warmer thermal trough forming near or at the Coast Sunday-Monday.  Depending on the positioning, this could bring the 80-90 degree temps to the beaches Sunday.  Something to keep an eye on.

The posting times are going to change since my shift has changed slightly.  Most nights I'll be leaving right after the 10:36pm weathercast since I'm coming in a bit earlier for our 4-6pm newscasts.  So…I need to post a bit earlier.  We'll see how it goes…Mark Nelsen

    Update*
    Okay after carefully dissecting the latest WV image I am beginning to see signs perhaps the dry air that had been persistently eating away Ike’s NW circulation may be lessening.
    I’m seeing some enhancement wrapping around Ike’s northern COC….
    Keep an eye on this.
    Okay back to our weather….
    Pressure pattern is in the process of switching to offshore.
    [Surface gradients]
    As of 8 PM
    [NW Marine-Columbia River]
    AST-PDX: +1.5
    AST-DLS: +1.7
    [SW Marine-Central Valley]
    OTH-SLE: +0.3
    OTH-EUG: +0.8

    PDX-DLS: +0.2
    TTD-DLS: -0.5

    OTH-GEG: -2.8

    Latest WV Image shows yet more dry air pulling around Ike’s southern circulation near 23 N close to his inner core..
    I am going against the grain it seems in not expecting rapid deepening for at least 12 hours.

    Perhaps Triforce,
    I’ll have to ask my mom how she’s feeling; she starts aching several days before a storm comes in too. Never hurts to call and say “hi” in any event.
    Wrath,
    I agree, Ike seems to be mostly spinning in place for the moment. I wonder what the surf is like on the west coast of Florida.
    68.4 currently. 5th 80+ day in a row with 80.8 for a high today.

  6. TriforceofInvisibility says:

    71F and sunny but a lot of farm haze much unlike yesterday. Mom’s Arthritis is acting up bad today. 😦 She usually feels storms on average a week before they come.
    Perhaps somethings coming down the horizon that will pop up on the GFS maps.

    Updated Ike thoughts..
    Ike is really fighting right now.
    What do I mean? He is ingesting a lot of dry air not only to his west and southwest side of circulation, but also seeing some near his northern inner core. You can also see the westerly shear eroding and inhibiting any outflow/spiral banding to Ike’s western periphery. Now in comparison the eastern/southeastern side of Ike is very healthy. If we were to see that becoming symmetrical I have no doubt that Ike would deepen rapidly possibly to CAT 4 within 12-18 hours. (I do not expect this).
    When I look closely at various loops it seems evident that Ike is bumping into the ridge of Mexico which is acting as a force field not allowing him to move westward or anywhere fast.
    Ike is waiting for the ridge to cooperate before he can make his move, but I’m not seeing that cooperation. He’s sort of jogging/meandering to the WNW/NW and is now just below 25 N. In all honesty I am unsure he moves WNW on a B-Line for the Corpus Christi/Galveston area.
    These are just thoughts I’ve had. I do still expect Ike to veer off to the left hitting Texas.

    “He didn’t want to set a date, but said that he expected scientists would be able to conduct collisions for their experiments “within a few months.”

    Here is the full article which the headlines are VERY misleading. http://www.katu.com/news/national/28133709.html
    First the (thing) said it fired both protons against each other but if you read farther down it said it fired one counterclock-wise and the other clock-wise NOT into each other.
    Triforce is confused but he will have to put up with being confused as usual.
    The part about the counterclock wise.
    Paragraph 2. (At least Triforce think that’s a paragraph cause he doesn’t know what one is)
    “After a series of trial runs, two white dots flashed on a computer screen at 10:26 a.m. (0826 GMT) indicating that the protons had traveled clockwise along the full length of the 4 billion Swiss franc (US$3.8 billion) Large Hadron Collider – described as the biggest physics experiment in history.
    “There it is,” project leader Lyn Evans said when the beam completed its lap.
    Champagne corks popped in labs as far away as Chicago, where contributing and competing scientists watched the proceedings by satellite.
    Five hours later, scientists successfully fired a beam counterclockwise.
    Physicists around the world now have much greater power to smash the components of atoms together in attempts to learn about their structure.
    “Well done, everybody,” said Robert Aymar, director-general of the European Organization for Nuclear Research, to cheers from the assembled scientists in the collider’s control room at the Swiss-French border.
    The organization, known by its French acronym CERN, began firing the protons – a type of subatomic particle – around the tunnel in stages less than an hour earlier, with the first beam injection at 9:35 a.m. (0735 GMT).
    Eventually two beams will be fired at the same time in opposite directions with the aim of recreating conditions a split second after the big bang, which scientists theorize was the massive explosion that created the universe.”
    See it hasn’t happened yet so don’t say things are all quiet.

    The blach hole problme is suppose to happen when the protons smash into each other. Today they were suppose to fire the first shot clockwise. I reread the article on KATU so I KNOW. They said it will be about a month before they do the full deal.
    Either that or I am insane but that is what I read.
