Weather Forecast is all over the place this weekend (27 - 28 May)

From yesterdays forecast I would have called this weekend flyable all weekend long. What a difference another 12 hours makes. I am not sure now.

For Today, from the BOM, today looks more possible over tomorrow. The Blipmap is now calling the winds to be from the NE and light early (which is what we are seeing on the Mt Boyce current readings) but later the wind will swing round to the NW and increase to >10Kts. Windity is also forecasting this to happen after the low cloud clears after 9:00AM. So Today could be flyable, depending on how well the wind comes around in the afternoon. Advanced pilots may be able to take advantage of the NW and lighter conditions to soar the North cliffs early, but should be careful (as always) that the wind doesn't come too far around to the West and make the North face trashy.

Like last Sunday (which I think i got wrong), it is defiantly a call from the hill by some experienced pilots.

For Sunday, the forecast now looks trash from BOM, with showers developing and the wind increasing throughout the day. Windity is not forecasting any rain, but does agree with the increasing winds, which may get too strong for flying from midday. If you are out early it may be a nice morning, but beware of the wind mixing down from high as the morning progresses. It is a classic trap that has caught out a lot of (experienced) pilots, where it is a lovely soaring morning, but as soon as some thermals start it gets blown out and before you know it your stuck up behind launch getting trashed. But if you are keen, early is key.

With the forecast being a little unreliable lately, I cant stress how important it is to have one of the BMHGC SOs present to make a call on the weather before you launch.

Good flying
