So how many days were there between the SSW in 2018 and the first wintry event after that? Let's do some calculations and transpose that interval onto the projected date of the SSW this March and when the first wintry event may occur after that?
Let's say it's 20 days.... so we're talking about right after the Equinox to the middle of April to get something decent....we could have two wintry events in that time.
