A significant change in the weather pattern is about to unfold over large areas of the United States as an extended warm spell develops more than two weeks after the official start of spring. In some areas, it could become downright hot, according to AccuWeather meteorologists.

Temperatures will reach levels that have not been experienced since last fall for many areas in the central and eastern U.S., allowing lawns to turn greener and flowers to continue to bloom.
