Concern is rising that the first major storm outbreak in the run-up to spring could strike the nation’s heartland, putting millions of Americans from Texas to Iowa at risk of potentially strong tornadoes.
Some scattered severe thunderstorms were expected to begin firing up late Thursday in the Texas Panhandle and across western Oklahoma and parts of Kansas, the National Weather Service said. Large hail, damaging winds and possibly a few tornadoes were also expected, according to the forecasters.
But the strongest storms were expected Friday in a zone that includes much of Oklahoma, Kansas and Missouri and extends into some nearby states, according to weather service projections.
More than 6 million Americans are at the highest risk of severe weather Friday in an area that includes the metropolitan areas of Kansas City and Tulsa, Oklahoma, according to the national Storm Prediction Center. Another 22 million people are at a slightly lesser risk in a zone that includes Oklahoma City; St. Louis; Omaha, Nebraska; and Milwaukee, Wisconsin.
The general setup for the strong storms is a clash between warm air streaming north from the Gulf coast and cooler Canadian air behind cold fronts, according to meteorologists with the private forecasting service AccuWeather.
In parts of the eastern U.S., this weather pattern is also expected to usher in extremely warm temperatures for this time of year by the weekend.
“Temperatures will be 20-30 degrees above average, with 80s reaching as far north as parts of the Ohio Valley and Mid-Atlantic,” federal forecasters wrote in their long-range forecast discussion. “Daily records could become widespread.”
The high temperature in Louisville, Kentucky, for instance, is expected to reach 81 degrees (27.2 Celsius) by Friday, the weather service predicts. Atlanta’s high temperature is expected to hit 82 degrees (27.8 Celsius) by Saturday. The forecast for Washington, D.C., calls for a high temperature of 74 degrees (23.3 Celsius) on Saturday.
The spring storms in the forecast come near the start of what many call tornado season, which generally begins at different times in different parts of the United States.
In what has historically been known as Tornado Alley — a designation that typically includes Kansas, Oklahoma and Texas — the peak of tornado season is May into early June. But the season starts earlier in what’s often called Dixie Alley made up of southern states such as Arkansas, Louisiana, Mississippi, Alabama and Georgia.
Experts recommend a few simple safety steps to take before tornadoes hit.
