Weekend Weather Outlook

Dry weather allows many regions of the country to enjoy outdoor activities as spring begins to settle in during the first “official” weekend of spring.

Sunday

Lingering moisture will inch its way into the Northeast this Sunday as wet weather spreads to most of the Northeast by late evening. This wet weather will consist of a rain and snow mix, bringing some patches of icy conditions to the Northeast, except for coastal areas. Accumulating snow is possible for parts of Vermont, New Hampshire, and Maine.

However, the Mid-Atlantic, Southeast, and Deep South will see continued dry conditions from today, closing out the first weekend of spring with dry weather bliss. Later into the night, the Mid-Atlantic may see a few thunderstorms and rain showers, with it being scattered activity.

The Lower Midwest and Ohio Valley will see scattered stormy weather late on Sunday. The main threats will be hail and damaging wind gusts with any established storms. Wet weather will persist along the U.S.-Canada border, with some patches of iciness throughout a rain/snow mix over the Northern Plains and Great Lakes. The remainder of the Midwest will be dry.

The Mountain West will also see similar weather trends, with the northern Rockies having some precipitation clutching the higher mountainous peaks. Light snow is possible to top the snowpack on the mountain peaks, while a rain/snow mix will fall into the foothills.

The Pacific Northwest will continue to experience a dry first Sunday of spring, with the only precipitation in the region holding to the Cascades and Olympics. Snow should top the snowpack in the mountains, while the densely populated valleys will remain dry.

The Desert Southwest, Great Basin Desert, and entirety of California will be dry this Sunday, ending the dry weekend with a proper introduction to springtime bliss.

Chillier temperatures settle southward this Sunday, as the U.S.-Canada border, northern Rockies, and Cascades will all be below freezing again, but some regions could dip down into the low 20s during the day. Forties can be expected in the interior Northeast, Great Lakes, Northern Plains, and foothills of the northern Rockies and northern Cascades. Fifties will persist along the New England coastline, southern Great Lakes, Central Plains, and the central Rockies. 

Sixties are to be present just a bit southward of these regions, with 60s dominating in the Great Basin Desert and California’s Central Valley as well. Areas seeing 70s on Sunday will be the Appalachian spine down through the Tennessee Valley, the Southern Plains, and coastal Southern California. Eighties will be more dominant this Sunday in several regions. This includes the Southeast, Deep South, and Southern Plains.

There will be more regions in the 90s this Sunday than today, but this is isolated to north-central Texas and the Desert Southwest, stuck beneath a strong early-season heat dome.
