The prospect was for the core of the sub-tropical anticyclone to reign supreme and generally restrict convective cloud development. There was also the outside consideration though that, being more on the edge of this zone of descending air; some alto-level inflow of tropical air could appear. Interestingly, the one aspect faltered and the other became more prominent. Considering the overall dryness of the air, we did not do too badly.From Saturday onwards, isolated convective development has been visible both by sight and by satellite observation. Rainfall reports are certainly scant and, where recorded, have shown the limited precipitation activity

Last Thursday and Friday were as expected. Nothing much happened weatherwise. But by Saturday, the scene was changing rapidly. Aerodrome forecasts had to be revised as the weak cold front stagnated and a cut-off vortex began deepening. The increasing alto-level clouds thickened and increased their rate of movement. This turbulence even caused a slight hail shower over the show grounds.
