Can't comment on the current snow conditions but there looked to be plenty of the white stuff still left on it as seen from Beinn Chabhair on Saturday just gone - hope that helps.
Drove past on Sunday, still a fair bit up there, FWIW northerly aspects a bit further north where still icy enough to warrant the use of crampons or stiff boots to make progress.
Hiked up Ben Lui and its neighbours on Thursday. We came up Ben Lui via the corrie on the north ridge. The north ridge you needed crampons when in the shade. Snow and ice was very variable going from slush to bullet hard without rhyme or reason. The corrie had snow down to bowl but the cornices were seriously dripping. Snow patchy on it elsewhere.
Similar to snow fields on Ben Oss, especially the remaining extensive coverage on the north east ridge leading to bealach with Beinn Dubhchraig, with a thin layer of slushy snow covering most, but not all snow.
