April and May are known as tornado months. June through November is hurricane season. California is subject to earthquakes. The Midwest gets tornados all the time. Florida is susceptible to hurricanes. And New England is subject to cold and snowy winters and hot and humid summers. But do you know why there has been more extreme weather the past few years than ever? I'll give you a hint: it's not global warming.
Every year on or around April 25th on Saint Mark's Day, the Greater Litanies are to be held as part of the liturgy. A Rogation procession is to be held on the church property. This started in Rome and Venice (patron is St. Mark) in the early Church after the catacombs. (My parish has one every year.)
During the 400's, several inclement acts of nature took place in Vienne, Gaul (present-day France). In result, Saint Mamertus, the bishop of the diocese at the time, ordered that Rogation processions take place on the Monday, Tuesday, and Wednesday before Ascension Thursday. These are known as the Lesser Litanies.
Eventually, all four litanies became part of the liturgy of the universal Church. The purpose of them is to ask God for good weather and crops for harvest. Plain and simple. The ignorance of the Novus Ordo Church on avoiding these penitential acts (because purple vestments are to be worn) clearly is a contributing factor of bad weather.
