We have heard thunder twice now in 2021. The first time was January 26th. The second time was today, February 11th. According to the old wives’ tale, expect measurable snow in the next 10 days!
Not so fast! In the last 5 Meteorological winters (winter 2017 – winter 2021) which are classified as December, January and February there have been 17 winter days with thunder, and only one of those times did we see measurable snow within 10 days.
Meaning in the last 5 years, only 6% of the time did we had measurable snow within 10 days of hearing thunder. The truth and data of it is, it rarely snows within that window. It is possible, but rare.
