Urgent Help Needed!!!

[SASless]

Crisis of some great dimension here....a PPruner needs help!

Boss Fellah had me check the weather forecasts for tomorrow...we are to fly some of our Museum warbirds up to Arlington, WA. for the annual EAA Fly-In and Airshow. The rub is we really do not want to expose the aircraft to flying in rain for its adverse effects upon the paint and rotating components.

Now being the dutiful subordinate....I did as requested and discovered the forecasters giving a report that shows the "percentage of precipitation" as being of all things...."50 percent"!

Being a former math whiz...I figure that is the chance of rain on any given day....either it rains or it does not. My Boss Fellah being neither a math whiz nor a person tolerant of wishy-washy answers....is putting me on the spot.

Just what do I tell him....is it an even chance it will rain all over the area, even chance it will rain at each discrete point of the area, it will probably rain........whats a feller to do here?

I wish to appear decisive...professional...get to fly the warbirds....but the ramifications of standing in a downpour and trying to explain the finer points of weather guessing with the Boss Fellah is not a thing I wish to think about....I am quite sure he would find my explanations somewhat inadequate.

Any ideas are welcome!:confused:

You are absolutely right there is always a 50/50 chance of rain, because it is either going to rain or not. However, knowing that people in the state of Washington have been known to have webbed feet, one would guess that you have a slightly better than 50/50 chance of rain. Oh and don't forget that Arlington is right over the "Convergence Zone" for the Puget Sound that has to be good for another 10% in favor of rain.

Of course this is but the opinion of one very young kid whose feet have begun to grow additional skin between the toes:hmm:

[Gomer Pylot]

The 50% means that there is a 50% chance that any one spot will get rain. That being the case, it's almost certain that there will be rain showers, which you may or may not be able to avoid. Sometimes the showers converge into solid lines. ISTR that the weather guessers were a little off once, I just can't remember when. :rolleyes:

[Drooping Turns]

Here's what you do. Fly up the East side of the Cascades to say Wenatchee. Zero chance of rain that way. Check the Wx from there or while enroute. If its raining in Arlington, stay put in Wenatchee until it clears or RON. Repeat as needed. Your 90% there.

Or stop in Hood River and we'll put you up and guard your planes.

Drooping Turns....in Hood River.....why sir...have we met? Sounds like the makings of a Pprune Bash....say the Wildflower Cafe in Mosier? Best Reuben Sandwiches in the Northwest!:ok:


By the way...were you involved in Cherry Drying this year?

Following your logic ... does that mean that everytime I go flying, I have a 50 % chance of crashing? I like to think not!!

[Jez]

Fly via Australia.

It hasn't rained here for bloody ages!!

gomexjr, think you need to go and think about probability some more - and stay away from the roulette wheel! You did make me chuckle ;) . Following on from Scattercat's comments, according to your logic if I buy a lottery ticket I've a 50/50 chance of winning - 'cos I either win or I don't. Now that's a classic.:}

SASless, think about the 50% as being a 50/50 chance that it will rain in the forecast area over the duration of the forecast, scattered throughout the area in his terms. Just tell the boss it's an evens chance, but you don't have a crystal ball - if you did, you'd be in Vegas earning a fortune.

So da boss has a choice just like putting the welfare of the warbirds on one toss of a coin or spin of the roulette wheel on lets say black. You've got to make him understand that for a start. Nothing you can do to predict further than that.

However, let him know that as a highly skilled aviator you can get the odds slightly more in his favour by going up and having a look on the day - maybe you can dodge the rain as others have suggested. But if you've got a line in front of you, then just tell him you'll be turning for home if he doesn't want his planes to get wet.

Bottom line that he's got to understand is that there is a risk. I'd say about a 40% chance of his planes getting wet, given the 50% chance of rain, but with you weaving about the sky to avoid. Ball should be back in his court - does he want to take the risk. You've explained it to him, shouldn't be up to you to decide.

But then there's Murphey's Law.

'What can go wrong, will.'

That means your 50/50 just became 60/40 against going flying.

Sorted!...though I'm not sure that's the answer you want to hear:ugh:

This reminds me of something that's stuck in my gord over the years...

I was once conducting flight tests on a deployed USN ship whose CO (black shoe type) was fond of saying;

"No PLAN ever survived initial contact with a HELICOPTER!"


If you go, it'll rain. If not, spf-15 sales will set records. :D

forecast, schmorecast! Enough of this dithering and russian roulette with Mother Nature. Instead, go Prophylactic!

(Get your mind out of the gutter, now . . .)

Load the bomb bays with enormous rolls of industrial-grade Saran Wrap. Make a terminal-velocity dive to Arlington between showers (all the way from Wenatchee), screech to a halt, have the seminaked buxom greeting-ground-crew roll the wrap over the bird.

Voila! Retire to bar. Wait 8 months for a clear day, depart for dryer climes.

Maybe you need one of these:

"Our helicopters said that rain will arrive at 14.35 but said 'I'm 90 percent certain it is going to pass to the north of the circuit and it is going to miss the circuit' and they were exactly right," Richards said. "It missed the circuit by one mile."

Thats an impressive helicopter - I wonder if it has lights flash along the front when it does its weather prediction :}

[when I first read the title of that story, "Helicopter holds key to Button win", I had a totally more literal image in mind :rolleyes: ]

This proability stuff is easy - it is going to rain, absolutely 100% sure - the difficult bit is when!! and where!!

[SASless]

Well, the crisis for this weekend is over...

I called upon every weather outlet known to man...even got out the see thru bowling ball and divining rod....and after careful consideration and studied analysis of all the data...when confronted by the Boss Fellah, I made a most definitive statement which he accepted with the best of grace.

I detailed the contents of the various sources, compared and contrasted the data, gave a subjective opinon about just how accurate Met people can be and then made my position clear.

When he asked me "Is it going to bloody rain or not?"...I submitted that for this issue, I was in Sales .... not Management... and that I would have to defer to a higher power on that question.

What was I thinking?

:uhoh:

For the good folks at the Arlington Airshow...unfortunately it was a very rainy day...we stayed home but would really have liked to have gone up there. They put on a very impressive show and the EAA enthusiasts show up in mass for that event. :ok:

Nice one SASless!!:ok:

[gomexjr]

SASless - Sorry to hear you weren't able to make it up here. The rain was just enough to keep the temperature down, and it would have been great to see the aircraft....and of course yourself as well.

Scattercat & Maximum - to further expanded on upon my logic and reasoning, which happens to be neither logical nor reasonable. I hit 100% for weekend as I will claim 50% for the rain and I didn't win the lotto again giving me the other 50%, thus adding up to a perfect weekend of being 100% correct :p

.............now I understand!! :confused: :p :ok:
