This post has been updated with data through March 15.

With snow still on the ground following our exceptional last month and a half, I thought it would be fun to list the records we broke or got close to breaking. These records are for the Tri-Cities and are considered unofficial. I’ve listed the old records as well, and the year they were set. Records began in 1894.
