Last Year a thunderstorm moved through and it produced winds so strong it shook my house. I was wondering what wind speed range that would be considered. I was also wondering if a thunderstorm that downed one inch branches is considered high end strong or low end severe.

Hard to say, not knowing how your house is constructed and what qualifies as shaking. You could try to use the Beaufort Scale to estimate:

QUOTE
Strong gale - 47 to 54 mph: Some branches break off trees, and some small trees blow over. Construction/temporary signs and barricades blow over. Damage to circus tents and canopies.


Since winds over 58 mph are required for a thunderstorm to be classified as "severe", you were probably near that classification. Did the NWS have a warning out for your storm, where they quoted specific wind speeds?
