“In this league with a player like that, you got to bring all types of pressure,” center Mercedes Russell said.

A six- to 10-hour window of moderate rains will cross through Mississippi, Alabama and Tennessee during the second half of Saturday into the overnight or early Sunday, while a lighter region of “wraparound” rains pinwheels back west around the low pressure center.

“But it will matter where that high pressure center sets up, how strong, and if it persists.”

Throughout the winter, the polar vortex — an upper level low pressure center surrounded by a belt of west-to-east winds in the upper troposphere and lower stratosphere — was exceptionally strong.

Over the years, its Israel-based researchers have developed a wide range of energy- and cost-efficient desalination processes, including using “waste steam” to generate electricity, and a proprietary “pressure center” that allows large plants to perform maintenance via the Internet.
