A low-pressure system that has lingered in the Gulf of Mexico the past few days, bringing rain to the Gulf Coast, was expected to finally move inland into the Southeast on Sunday. This was likely to translate to widespread rain and even a few thunderstorms in the area even as the system weakens while moving toward the Southeast coast.

To the north, a large high-pressure system was anticipated to move northward into northern New England, providing dry conditions through the Northeast and Great Lakes.

Meanwhile, a weak cold front was expected to scrape through the Plains and Upper Midwest. There was not a large amount of moisture expected with this front, but a few showers were possible in Minnesota and Wisconsin.

In the West, another strong Pacific storm was likely to slam into the Northwest. Washington and Oregon were predicted to receive the brunt of this storm as it provided significant rain and high-elevation snow mainly in the morning. The storm was then expected to then slide eastward, where additional snow was likely to fall in the Intermountain West.

Northeast temperatures were expected to rise into the 40s and 50s, while the Southeast was likely to face temperatures in the 50s, 60s, and 70s. The Northwest was anticipated to have weather in the 30s and 40s, while the Rockies were likely to see similar temperatures.

Temperatures in the Lower 48 states Saturday ranged from a low of 7 degrees at Gunnison County, Colo., to a high of 86 degrees at Lakeland, Fla.
