If you're hoping to fly at Blackheath this long weekend, I suspect Friday will be your only chance.
At present, it looks like a cracking day, although spring punch in the air.
Light westerly winds all day. Base at about 2600, 3+ m/s climbs (probably peaks of 6). Not ridge soarable, you'll need the thermals.
I reckon it'll be on properly by 11am. If you're a lower airtime pilot, plan to fly early (why not start with a sleddie at 9, then a second flight, landing by noon), then flying again at 3.30 - 4pm when it mellows out again. The early afternoon promises to be strong.
Minimal chance of seabreeze coming through before 6pm.
I'll update closer to the day as the forecast resolves.
