Old wives tale :Thunder in Winter.Snow in 7 Days.This week we won't be looking, rather, we'll be listening for the sound of thunder in the sky. As the saying alleges, roughly 7 days after a thunderstorm, snow will be falling. FROM the Old Farmers Almanac
For every thunder with rain in February, there will be a cold spell in May.
Thunder in September brings plenty of snow in February.
Thunder in spring, Cold will bring.
