Scattered showers and thunderstorms are expected in the South on Sunday, while wet weather returns to the West Coast. A low pressure system moving across eastern Canada will continue pushing a cold front through the Great Lakes and into the Ohio River Valley. Moisture associated with this system will be limited, with only a few showers and thunderstorms are likely. The tail end of this frontal boundary will stall over the Southern plains, pulling moisture from the Gulf of Mexico. This will support more showers and thunderstorms throughout the day, some possibly turning severe in the afternoon and evening with a threat of strong winds and large hail.
Further east, a low pressure system is sliding up the East Coast and into the far Northeast. Once this system moves into these cooler temperatures, expect a wintry mix of freezing rain and snow showers to develop across Maine.
Out West, a strong low pressure system spinning off northern California and Oregon remains relatively stationary and is pushing a cold front toward the coast. The front is not expected to head inland, triggering more coastal showers for the region on Sunday.
Elsewhere, a high pressure building in from the Southwest will allow for a warming trend to persist for the rest of the Western U.S. Temperatures in the lower 48 states ranged Saturday from a morning low of 1 degree at Stanley, Idaho, to a high of 88 at Harlingen, Texas.
