If there is an early season storm then there could be snow. If not then not.

Last year in early October there was an early storm (and then nothing for a long time). I went to Cottonwood Lakes a few days after the storm and there was a fair amount of snow, nothing unmanageable. At that time of year, if it has snowed and then cleared up, it's pretty warm and I would expect the snow to be soft. If this happens you would probably benefit more from snowshoes (or skis) than crampons.

It can snow heavily in October, it did so as recently as 2009, not to mention the fact it also snowed significantly in 2010 and 2011. You'll probably be fine without crampons, but don't necessarily count on it.
