OKLAHOMA CITY (AP) — National weather forecasters have issued a strongly worded warning well ahead of possible severe weather in states across the middle of the country.
It's only the second time in U.S. history that the Storm Prediction Center has issued such an unusually early and strong warning more than 24 hours in advance.
The warning says conditions are ripe for violent tornadoes to rip through the nation from Texas to Minnesota this weekend.
As states across the middle of the country prepared for the worst, storms were already kicking off in Norman, Okla., where a twister whizzed by the nation's tornado forecasting headquarters but caused little damage.
The center says this weekend's outbreak could be a "high-end, life threatening event.
The worst weather is expected to develop late Saturday afternoon between Oklahoma City and Salina, Kan.
