After days of searing heat, much cooler air will dive southward into the central and southern Plains today.
Residents from central Nebraska to the panhandle of Texas will welcome the arrival of more comfortable and refreshing air after scorching hot temperatures surged into the 90s over the past several days.
Responsible for the cooler air will be a cold front that passes through the region this morning. This front is associated with a storm system that will ignite powerful severe thunderstorms across the Midwest and the southern Plains, including Des Moines, Iowa, St. Louis, Mo., and Tulsa, Okla.
The cooler air will be ushered in on gusty northerly winds. Many places will have gusts between 40 and 50 mph. Strong gusty winds can cause damage to power lines, leading to power outages.
Temperatures across the region will be 20 to 30 degrees colder today than they were the past several days.
High temperatures today will range from the mid-60s in central Nebraska to the mid-70s in the panhandle of Texas.
Residents from Iowa to eastern Oklahoma will have to wait one more day before they receive any relief from the heat.
Unfortunately, relief from the blazing hot temperatures will come at the cost of drenching and perhaps damaging severe thunderstorms.
Once the storm system finally pushes eastward, high pressure will build into the nation's midsection, providing gorgeous weather with plenty of bright sunshine.
