'Omega block' pattern to dominate weather across US this week

An 'omega block' pattern expected to dominate weather across the nation this week. This overarching pattern occurs when a ridge of high pressure sets up over parts of the Western U.S. with an area of low pressure on each side of the ridge. The East and West coasts are forecasted to stay stormy and cool while the central U.S. will see a surge of warm air.
