If daytime temps will be high, and/or you'll have to get into the snowy slopes in the afternoon, snowshoes can be worth the weight. I like smaller ones with aggressive crampons (eg MSR Lightning). Depending on slope steepness and runout, crampons can be a good idea, and potentially an ice axe as well. I don't like Microspikes in this application, as you'll often get an inch or two of corn atop hard snow. Proper crampons with hold in both.
Being familiar with how terrain holds snow (aspect, avy paths, areas prone to windloading, etc) will give you a decent idea of what conditions can be expected. Check area snotel sites, plot them on a map, and extrapolate to get an idea of snow depth.
A complex and fun topic.
