A strong upper-level feature in the southern jet stream triggered rain and thunderstorms across central Louisiana Friday night and Saturday. The coverage reflected a general rain, near 100%, and the amounts were beneficial.
There was a distinct preference for the higher amounts across Sabine, Natchitoches, and Winn Parishes. In that area, heavy thunderstorms were able to train, or repeat, over the same locations. Locally heavy rain frequently occurs in training patterns.
From a historical perspective, a two-inch rainfall in any 24-hour period occurs about five or six times per year in central Louisiana. A four-inch amount, such as that observed in Many, occurs only once per year.
And everyone said the rain was welcome.
