Weather prediction question.

[Stephan van Tonder]

Hi Guys - I'm sure it has been asked before but I just can't get a simple definite answer and perhaps there isn't one but help me out please. This friday morning I am doing a x-country - plan is Petit, Pinedene corridor, Harties, Aviator's paradise, Brits, Rust de winter dam, Cullinan - Petit. Take off time will be 06:30 and time taken max 3 hours( might stop for breakfast at aviator's)
Now I have looked at some 5 day weather forecasts and some predict rain - others 30% thunderstorms(which I assume is afternoon weather?) etc. Now on Friday morning at 05:00 I want to get up and know the weather 3 hours ahead and current. What is the easiest fastest way of getting a reasonably accurate prediction for the next 3 hours across that area and the current situation?. Weather SA TAF and Metars? or is there somewhere I can phone. It just doesn't seem simple cut and dried.

Try these as well:

Weathersa Taf and metars is accurate as well. Just remember that the metar is a report of current weather at time of report. Check for speci for notable change in weather. Taf will give you a forecast, with tempo % of change for specific hours, so you would get a accurate discription of weather for period. Also see spot graph of winds at certain flight levels.

Good luck.

PS: Just go and fly the conditions, if you are happy with them.

thanks guys. Massimo thanks that is a nice site - gives a breakdown every couple of hours which is what I was looking for.

Someone once asked a meteorologist "Where do you guys get this '75% chance of rain' stuff from?"

Meterologist replied "Well, there's 4 of us working here at the station, and 1 of us disagrees"



But that is a great site, thanks. Did you notice the Remember this page link at the top right- you can automatically go to your town next time you open the site.

I use the above site. If you are serious about wind, then look at the pigeon racing link to determine low level wind velocities. Lekker to use in an AIR RACE.....

Rudi's site is also comprehensive....

Rudi, had a look at you RV7 at EAA Bloem - that is some very neat work done there! The guys were seriously complimenting the finished product!

Hi Kevin, Sorry man it is a labour of love that is why it came out that way! I am not into the building for customer game yet. Currently I am looking forward to the next one...a RV12. The wing kit arrived yesterday...will post pictures soon here: http://www.avcom.co.za/phpBB3/viewtopic.php?f=1&t=37050

Maybe I should move my RV12 build thread from avcom here to microlighters, cause I think more MPL pilots want to upgrade to SPL, then PPL pilots down grade to SPL. So maybe there would be more interest here then on avcom ???

can't you post on both Rudi. I see you have a huge group following the post on Avcom, me for one.
