Weather

The core of the cold air mass that prevailed across the Northeast over the weekend will start to depart Monday, as a south to southwest breeze ushers milder air from the Ohio Valley and the Mid-Atlantic states into the lower Great Lakes and parts of New England. A new cold air mass is projected to push across the upper Great Lakes, bringing rain and snow showers. The air mass may produce accumulating snow in northern New England on Tuesday night and early Wednesday.

Most areas from North Texas and the southern Plains to the Southeast coast can expect a dry and cool day. For many parts of the Southeast, these may be the coolest daytime conditions in many months. Rain will drench parts of South and coastal Texas, with possible flash flooding. The rain is projected to push east with a tropical system later in the week, and it could affect areas slammed by Hurricane Michael a few weeks ago.

Most of the West should remain dry. A pocket of clouds, showers and a few thunderstorms will develop over parts of Arizona, Colorado, New Mexico and Utah. Air stagnation may result in poor air quality in parts of the Northwest. The first in a series of storms is expected to arrive later this week, bringing wind and rain.

FOCUS: Potential Coastal Storm This Weekend

Travel delays may occur in the East this weekend as a storm develops along the East Coast. Early indications are that the storm will strengthen as it moves north from the Carolinas, with soaking rain and gusty winds along the coast and inland snow possible in the north.
