The nation's weather
Weather UndergroundWet weather was expected to continue in the Pacific Northwest on Wednesday, while another low pressure system was forecast to move into the Southwest from Mexico.
A low pressure system that developed over Mexico was forecast to push northeast, over the Southern Rockies and into the Southern Plains. The system has picked up moisture from the Pacific Ocean and was expected to pull in additional moisture from the Gulf of Mexico, which could create scattered snow showers over New Mexico and western Texas. Between 1 and 3 inches was expected.
Widespread scattered rain showers were expected over most of the Southwest. The heaviest rain was likely to fall over the Texas-Mexico border, with the possibility of scattered thunderstorms.
Meanwhile, high pressure was forecast to build over the Northern Plains and Great Lakes from Canada. This could allow for cool and dry air to pour in from the north, allowing for highs to remain in the 20s with plenty of sunshine. However, the low pressure system that the ridge was expected to replace could continue moving east and leave about an inch of snow in New England.
To the south, a strong low pressure system was forecast to continue tracking up the East Coast. It was expected to pull moisture from the Atlantic Ocean, and with temperatures hovering near freezing could allow for scattered snowfall over the Mid-Atlantic states. Snowfall was expected to taper off throughout the day as the system pushed farther offshore.
In the West, a Pacific storm spinning offshore was expected to continue pushing a cold front over the Pacific Northwest. It could bring another day of light rain to northern California, Oregon and Washington, with light snow at higher elevations. The Cascades and Sierras could see between 1 and 2 inches of snow.
On Tuesday, temperatures in the Lower 48 states ranged from a low of negative 16 degrees at Clayton Lake, Maine, to a high of 84 degrees at Kendall, Fla.
