As others have said, be prepared for anything, however as I'm  frequently in the hills I can give a quick update on snow conditions. There is quite a lot of snow above 900m with considerable patches on N facing slopes and in corries down to 700m or so. There was fresh snow on Thursday so that 900m and higher on Ben Eighe and on Slioch were completely white. The Cairngorms look solid white too, again only higher up.
If you're going over the summits of Munros you can probably avoid taking crampons and ice axe as long as you keep to ridges which are generally clear (avoiding cornices of course) and are prepared to take detours around large patches or to potentially abandon summit attempts.
I'm considering taking B1 boots for the first week which are stiffer and better in snow.
Having said all this the snow is melting albeit slowly as daytime temperatures at 900m are hardly above freezing.
Can send pics if you'd like to email me.
