Tens of millions of Americans awoke to temperatures that feltmore like winter than springon April 7, and forecasters warned of another overnight freeze to come.
Freeze warnings extended across states from the Midwest to the East Coast, including Illinois, Indiana, Ohio, West Virginia, Virginia, Maryland, Pennsylvania, Delaware and New Jersey. Several areas will also be under a freeze watch or warning the night of April 7 into the early morning of April 8, the National Weather Service warned.
Temperatures were expected to drop as low as the 20s, the weather service said.
Cold conditions should last through about midweek, with daytime highs in major Northeast cities, including Boston and New York City, remaining in the 40s through April 8 before "rapid warming" begins later in the week, AccuWeather reported. In the Midwest, daytime highs could struggle to get above the 30s, according to the outlet.
Snow showers and flurries are also expected in parts of Pennsylvania, northern New Jersey, New York and into New England on April 7.

Florida drenched with rain, elevating flood risk
A slow-moving storm system was drivinglingering showers and thunderstorms over parts of Florida, helping ease an ongoing drought but also bringing a risk of flash flooding and hazardous coastal conditions along the eastern part of the state through at least the middle of the week, forecasters said.

The Atlantic coastline will be most at risk for heavy rain, with cities including Miami, Daytona Beach, Orlando and Jacksonville in the targeted region, AccuWeather reported.
Rainfall could total between 1 and 3 inches along the Atlantic coast and much of South Florida, with some localized areas receiving 4 to 6 inches, AccuWeather reported. In some extreme cases where repeated storms move and linger over the same areas, up to 12 inches could fall, the outlet said.
Another kona storm to hit Hawaii after flooding destruction
Another "kona storm" is threatening already-battered Hawaii with more heavy rain and flood risks starting later on April 7 and through the end of the week.
Akona storm, or a kona low, is a "major weather producer," according to the weather service. The word "kona" refers to the side of the Hawaiian Islands that is usually sheltered from trade winds and rainfall. But a kona storm, a type of seasonal subtropical cyclone, can bring torrential rainfall.
This week's kona storm is expected to bring strong winds, widespread heavy rainfall and flooding risks to the state, the weather service said. The risk for mudslides is also elevated in areas already saturated byMarch's two destructive kona storms.
"Showers and thunderstorms will increase from Tuesday night through Thursday, with the most significant impacts expected beginning Thursday night as deeper tropical moisture spreads across the islands," AccuWeather reported.
