It's going to be partly clouded with some rain showers around, the wind could be from the north with gusts to 25kts in some of the heaver rain showers, then no significant weather later on.

In other words; not too bad of a day. :p

Under the old 9-hr TAF it would have been (about):

Can't see much difference myself:hmm:

Hmm, I wonder? My observation is that the 24 hours tafs seem to have a lot more PROBS and TEMPOS - hard enough for them to predict the weather 9 hours ahead, let alone 24. Also the 9 hour tafs were issued every 3 hours which was, in my opinion, a benefit in terms of accuracy.

I have a student planning a night cross-country flight this evening... one of the stops has the following TAF:

TAF KOKC 132325Z 1400/1424 17008KT P6SM FEW200

Makes it easy, I guess.

Drapes - console yourself in the fact that even those of us that use aviation met forecasts have to really engage brain to decode it all. :}

This is how it SHOULD be if Bletchley Park is ever reopened -

TAF EGNX 131658Z 1318/1418 34010KT 9999 BKN025 ok?

Now TEMPO 1318/1321 7000 SHRA
but theres a PROB40 TEMPO 1318/1320 34015G25KT 4000 +SHRA BKN014 BKN020CB alright?

It will BECME 1321/1324 7000 -RA BKN012, but TEMPO 1322/1403 itll be 4000 RA RADZ BKN008

Then guys it will BECME 1406/1409 9999 NSW SCT025 which is nice huh?

But after all that nonsense above it will BECME 1412/1415 08010KT but theres a PROB40 TEMPO 1412/1418 7000 SHRA=

I find decoding TAFS and METARS fiendishly difficult and have found this device (http://www.eyespymag.com/enigma_j/enigma_j_standalone.html) very helpful.

One simply types in the indecipherable met data and it is translated into an easily read format.

" it is translated into an easily read format."

Which does beg the question as to why met data is presented in the way it is....K.I.S.S. being one of my preferred acronyms....is there any particular reason.....other than one recognised format for all...that data cannot be simplified...or would that be too easy ?...or indeed has a change ever been proposed and rejected and if so...why ?

9 hour TAF's are not a lot of use when some of your sectors are around 14 hours or so. It's okay for the bugsmashing community but I find that the heavy metal people tend to ask difficult questions.

One thing tho - when Heat was a boy it was always "understood" that the last 6 hours of a 24 hour TAF was always a SWAG (scientific wild arsed guess)
I am frightened to ask what the last 12 hours of a 30 hour TAF are.

I have tried the "cloudy with sunny periods and rain showers clearing" mantra but somehow it dosn's seem to work. :confused::confused::confused:

At least the weather forcast for us Mariners was given in plain English,"Tyne winds light to variable,ect ect"

Never been to sea in my life (excluding channel crossings) but like many others, I suspect, I like listening to the shipping forecasts on the radio. Read properly it's as good as, or better than, a lot of poetry:ok:

TAFS could be turned into a rap, I suppose :eek:

Not a particular fan of the 24 hour TAF, as heatseeker says the last few hours are a bit of a SWAG. Really I think they are an extended 9 hours TAF with a bit of guessing.

I like Slasher's rewrite but I have to say for both TAFs and METARS. I prefer them as they are written. I actually find it easier to read in that format. The translated version to me is more difficult to take in. The format is easy, once you know the acronyms like RA or -DZ or GR. You can skim through it in seconds. So Con-pilot's summary; It's going to be partly clouded with some rain showers around, the wind could be from the north with gusts to 25kts in some of the heaver rain showers, then no significant weather later on.immediately springs to mind.

It's a bit like Morse code I suppose the more familiar you are with it the more it flows. The other advantage to the condensed version is that you can have a summary of the weather of a huge area on a single page.

Heatseeker, yes I realise that having flown long haul in a previous life but I think it was better for all when we had 9 hour and 24 hour TAFs. 30 hours TAFs are more akin to astrology!

The marine forecast zones were and are poetry in themselves.

"tyne, fisher, dogger bank, german bight"

pure magic

not too sure about south utsira, though.

seems a bit new fangled.

Spelling of all the above probably totally dodgy. I have never read one in my life, but listened to thousands.

The Shipping Forecast in the dulcet tones of Patrick Muirhead (I wonder where he is these days :}) followed by Sailing By and I'm asleep; it's a conditioned response.

Had to learn the old shipping regions at school so modern areas like Fitzroy are bewildering as is Channel Light Vessel Automatic. One has a soft spot for North Foreland.

The weather reports broadcast in Shetland use Beaufort's scale so I was always fishing around looking for a scale to convert to more meaningful terms for me.

wanders off, muttering "Strong gales, occasional storm force my arse. It was 45kt gusting 55kt when I landed..."

Made me larf, the shipping forecasts did. Something, something, followed by something horrible - GOOD!

Seemed so mean.
