The month of March started off pretty slow with little weather drama and dry conditions. That changed as we got close to the latter half of the month with precipitation in the form of rain and snow taking over.

Through the first 12 days of the month, we had only received 0.6 inches of snow. We had seen a few days of colder temperatures but generally, mercury readings were above average.
