Dry weather will prevail across New England ahead of a storm, with rain, ice and fog Saturday evening. Rain is expected from the Ohio Valley and the lower Great Lakes to the central Appalachians, lower Middle Atlantic and much of the Southeast. The rain may cause minor flooding in areas with poor drainage systems. The risk of urban flooding can worsen where leaves and snow are blocking drains. Dense fog may accompany the rain, especially where there is some snow on the ground. Severe storms are expected to carry over from Friday’s thunderstorms as they extend east across the Deep South. There is a risk of a few isolated tornadoes.

Farther west, the storm will produce heavy snow and gusty winds over parts of the northern Plains, northern Rockies and uppper Midwest. Wind and snow may cause blizzard conditions. The worst conditions are expected on the Interstate 90 and U.S. Route 20 corridors of the Plains. Dry air is projected to sweep across the southern Plains.

A new storm will drop south along the Pacific Coast. Expect low-elevation rain and mountain snow to extend from Oregon and Northern California to Nevada. Snow will fall on the Arizona mountains Saturday night.

FOCUS: Cold Air Into Southern California

Unseasonably cold air will surge south through California and Arizona in the wake of a storm Sunday and Sunday night. There may be a frost or freeze as far south as the mountains, interior valleys and desert areas of Southern California late Sunday night.
