It’s a Messy Week for Weather Across the U.S. Here’s What to Expect.

A series of powerful storms continues to wreak havoc across the United States on Tuesday, bringing significant weather of nearly every variety to large parts of the Pacific Northwest, the Plains, Midwest, South and East Coast.

• Heavy rain will hit the New York area from late Tuesday into Wednesday, with the potential for flooding and damaging winds.

• Severe weather and flooding is forecast from the Florida Panhandle to southern Maine.

• Blizzard conditions will persist in the High Plains through the Upper Midwest with potentially more on the way by the end of the week.

• A potent cold front will continue to affect the Pacific Northwest, bringing several feet of heavy snow and blizzard conditions across the Cascades. Heavy snow will also continue to blanket the Northern Rockies.

Rain, rain and more rain in the East.

The eastern third of the U.S. will see widespread hazardous weather Tuesday, mainly in the form of heavy rain capable of producing flooding from the Florida Panhandle all the way north to southern Maine, meteorologists said.

A moderate risk of excessive rainfall warning was in place early Tuesday through the evening from northern Virginia to southern New England, where up to three inches of rain could cover ground that is already highly saturated, and in some places covered with snow. Strong winds up to 50 miles per hour are also a concern Tuesday near the coast and elevated areas where gusts are likely to exceed 50 m.p.h.

Where there are strong winds, there are increased chances of power outages, weather experts warned.

Severe weather that could produce tornadoes was also expected to hit northern Florida to the Carolinas.

Around the New York tristate area, up to four inches of rain in combination with strong winds was expected late Tuesday into early Wednesday, raising the risk of significant river flooding around New Jersey, the Lower Hudson Valley and parts of Connecticut. A flood watch will be in effect around the area from the evening through midday Wednesday.

The Plains and Upper Midwest see dangerous blizzard conditions.

Heavy snow bands with snowfall rates around one inch per hour will settle over portions of the Upper Midwest, making for hazardous travel on Tuesday.

Snow will continue to be an issue in parts of the Plains, particularly around Boise, Idaho. Portions of the region will see blizzard conditions with up to six inches of snow coupled with winds up to 40 m.p.h. and gusts hitting 60 m.p.h. Valleys in the area might see five inches of snow, while mountain peaks could see 18 inches.

Around Milwaukee, snow will continue through Tuesday morning with snowfall rates of around an inch per hour. The additional inches of snow may contribute to slippery road condition for commuters.

Heavy snow continues in the Pacific Northwest.

A powerful cold front that crossed the Pacific Northwest on Monday night will continue to sock the region through Wednesday, forecasters said. The storm is expected to bring several feet of heavy snow and blizzard conditions across the Cascades.

Over a foot of snow was expected to slam the Northern Rockies of Idaho and Montana through Wednesday and the Sierra Nevada on Wednesday night.
