CLUB CONTEST

Back from the Gauteng regionals I am deskbound and the closest i can get to the monthly club contest is to do the Thursday nite prediction, below and then to watch the weather unfold on the Cam - well i hope they do get some diamond heights and long distances in!! (and that i won't be eating my hat)





The thursday nite prediction


"With the Gauntlet due on Saturday and the final two weeks of OLC approaching it is about time that we have a serious look at the weather
I can't fly in the time that Dick B will be here, but i hope to be able to post forecasts every two days (it will help to keep me of the pills in the asylum)

Saturday

The task setting will be interesting with ridges, thermals and wave working.

The airmass is not so moist (dewpoint 6C) but cool with a max temp of 17 and a trigger of 14.8C, so expect some cloud at lower than normal levels - but thermic cu should have bases from 4500 topping 7000ft

The winds are ideal, westerly to Renosterhoek and Southwesterly to George
At 14h00 they should be surface 20WSW, 30W at 5000, 50W at 10000ft, 60W at 15000ft and 70W at 20000ft

The wave forecast is however, STUNNING with wave predicted at 11h00 from 10000ft to 24000ft experience has taught that in the Worcester valley the wave will be contactable a lot lower!!!
The prediction at 14h00 in any event is wave from 8200ft at 2.7m/s through to 24000ft at 1.7m/s peaking at 3.4m/s at 14000ft

My guess is that if you don't already have a diamond height, now is the time to fill up the bottle, file the flightplan and launch at 10h30

Sunday is more interesting, with a very strong south easter combined with a front to the SW!!! (at least that is what raob says) The SE will be a very black one.

PS if these predictions all come out i will eat a hat (but not the one i fly with)!!!"


must say: "Wish i was there!!"
