Weather

The storm that brought heavy rain to the Southeast over the weekend will brush southeastern New England on Tuesday, bringing snow. A second, weakening storm from Canada will spread snow over parts of the Middle Atlantic. Most areas can expect less than 1 inch of accumulation, with up to a few inches in some spots. A mass of dry air is projected to push south across the rest of New England. Both storms should depart later in the day.

Most areas from the Great Lakes to the Southeast, the South-Central States and the Southwest can expect a dry day, with at least partial sunshine. High pressure will extend from the Great Lakes to the lower Mississippi Valley and the Four Corners region. The coldest air in the region will prevail over the Midwest, with cool conditions farther south, east of the Rockies. The Southwest should remain warm.

Snow will stretch from the northern Rockies to parts of the northern Plains and the Upper Midwest. Some rain and freezing rain may mix with snow east of the Rockies as warm air arrives. Rain is expected to drench areas from northwestern Oregon to western Washington. This may result in avalanches and flash flooding.

Focus: Cold Spreading Later This Week

The leading edge of an arctic air mass is expected to move into the northern Plains later Wednesday. By Thursday, the cold air will reach the Great Lakes. The Northeast is expected to turn significantly colder by Friday.
