The first in a string of stormy days for the eastern half of the nation is expected to begin later this afternoon across the central Plains. A potent disturbance digging into the nation's heartland will trigger spotty, strong thunderstorms toward evening.
Although the coverage area of these storms will be spotty, any thunderstorm can bring damaging winds and large hail. As with any thunderstorm, drenching, blinding rainfall is possible as well as lightning. If traveling, never drive through a flooded roadways and slow down when you encounter torrential rainfall.
Residents from Lubbock, Texas, to Wichita, Kan., should keep an eye to the sky this afternoon for potentially nasty weather. Later tonight, the severe threat shifts north and east into places such as Springfield and Kansas City, Mo.
The damaging winds from these storms can topple trees and power lines while hail can damage cars and housing.
By tomorrow, drier and cooler weather is expected to rush into the region on brisk northerly winds. This will make for a refreshingly cool week's end.
Farther east, however, the potent disturbance and associated cold front will spark stormy, wet conditions in the Mississippi and Ohio River valleys by Friday and Saturday.
On the northern side of this storm, a swath of rain will promote wet conditions for northern Wisconsin and the Upper Peninsula of Michigan tonight.
This moisture-laden, powerful storm system is just a precursor of fall storms to come this season. As we move into autumn, the jet stream dips farther south, allowing strong disturbances to sweep through the nation.
A storm system responsible for severe weather across the Plains over the past week, as well as the snow across the Rockies will advance eastward.
The Highway Fire started around 6:10 p.m. PDT Saturday near Corona, California, in the Prado Dam area in Riverside County, and grew from 30 to 175 acres in a matter of three hours.
For the second half of the weekend and into the week, rain and wind will replace the pleasant, sunny conditions of the first part of the weekend.
After a steady rain closes out the weekend, more showers and cooler air will persist through much of the week.
A pattern favoring waves of progressively cooler air will set up across much of the Midwest and Northeast during next week and could continue into early May.
Round after round of drenching rain will continue to cause flooding in the South, while another dose of rain may renew flooding in the Ohio Valley this weekend.
