Weather Situation
A trough is deepening offshore from the west coast associated with a low pressure system, as a high pressure system strengthens in the Bight. The high will move east on Monday, allowing the trough to return to the west coast. The trough will move inland ahead of a cold front brushing the south coast by Tuesday. A new ridge will build across the southwest coast from Wednesday.
