Cape Gauntlet Day 1

We might be having a contest :-)

At the moment the forecast for Saturday is as follows

Light WSW wind (10kph) to 4000ft thereafter increasing to 20 at 5000ft, 50 at 8000ft and 70 at 12000ft.
There is a strong inversion at 6800ft (at the level of the cold front layer 6500ft – 8200ft where there is a strong subsidence inversion)
The front is a katabatic cold front, 81km to the SE moving SE with cloud and precipitation ahead of the cold front.

Though the dewpoint is down at 2.4C, max temp is at 9.2C which makes everything cloudy - base at 2400ft and 4200ft with tops at 6800ft, with, somewhat unusually a prediction of rain.

The lower airmass is quite unstable with thermic activity upto 5000ft

Thermals are predicted with a trigger of 8.6C at 1 – 1.5ms to 5000ft with bases at, variously 3200ft and 4200ft.

Expected drop zone – the golf course.

See you at 9 am in the clubhouse for the briefing.
