How to find dates and details of all snowstorms that occurred so far this winter in an area of interest in usa?

Can't locate this type of info on any weather websites. Northern NH has had many snowstorms so far this winter. I am looking for the dates of these storms and possible aculation of each since Nov/Dec 2008 up to the present time (Feb 2009) focusing on Mt. Washington Valley/North Conway area & surrounding towns. How do I research this? Thanks in advance for your help.
