A congested atmospheric pattern known as an "omega block" has brought extreme downpours and thunderstorms to parts of the U.S. over the past week, with flood warnings issued Wednesday (May 7) for the southern coasts of Texas, Louisiana and Mississippi.
Abnormally wet and windy weather struck New England Saturday (May 3), The Washington Post reported, and storms rolled over the Rocky Mountains and southern Great Plains Monday (May 5) through Wednesday. While many Eastern, Southern and Western states have experienced adverse weather due to the omega block, conditions in the north-central U.S. have remained mild and clear due to the location of the block.
