Some tornadoes can continue through the night after dark.
The National Oceanic and Atmospheric Administration predicts that some of the most powerful tornadoes in history could hit Oklahoma and other nearby states on Monday.
NOAA's Storm Prediction Center in Norman, Oklahoma, issued the highest possible severe weather risk warning for multiple intense, long-track tornadoes Monday afternoon and evening.
Some tornadoes can last through the night after dark. Tornadoes at night can be very dangerous.
This is the first “high risk” designation for severe storms this year and the first in Oklahoma since 2019.
Tornado Alley's forecast includes the potential for significant severe storms from Nebraska to Texas, especially Kansas and Oklahoma.
All modes of severe weather are possible as storms are expected to develop and eventually move eastward, possibly rapidly forming a line of supercells.
Multiple strong tornadoes with large hailstones the size of softballs are possible. Destructive thunderstorms produced winds of up to 80 mph.
At 3:00 PM ET, storms will begin to develop from Nebraska to Kansas, from Kearny, Nebraska to Hays, Kansas.
Once a storm occurs, it is likely to quickly explode in size and initially “come out of nowhere”, so everyone needs to be on guard, especially in the area where it occurs.
Tornado watches may be issued before a storm develops. People need to be ready to respond to something as soon as it is issued.
Until 12:00 p.m. ET, tornado watch for “particularly dangerous conditions” for parts of south-central Kansas (including Wichita), much of Oklahoma (including OKC), and far north Texas (including Wichita Falls) Information has been issued.
By 6:00 PM ET, the storm is forming and rapidly developing from Nebraska to central Oklahoma. Strong and long tornadoes with large hailstones up to the size of softballs are possible at this time.
The storm will continue to move east by 8:00 PM ET and will now enter the Beatrice, Nebraska area along with Wichita, Kansas.
More storms are possible east of Oklahoma City, an area devastated by tornadoes in late April, by 12:00 ET. A storm line will then form from Tulsa, Oklahoma to Joplin, Missouri to Kansas City, Missouri, with the potential for all modes of severe weather.
The line continues into the Middle East overnight and finally disappears when it reaches Paducah, Kentucky by sunrise.
The new energy could bring another round of storms Tuesday and Wednesday.
