A strong low pressure system will continue to inch eastward across the southern tier of the country. This system will move slowly across the southern Plains and the lower Mississippi Valley. As warm, humid air interacts with this area of low pressure, strong to severe thunderstorms will develop across Texas, Oklahoma, Arkansas, Louisiana, Mississippi, Alabama, Tennessee and Kentucky.

These thunderstorms will be capable of producing large hail, dangerous straight line winds and isolated tornadoes. In addition, heavy rain associated with these thunderstorms will bring a threat of flash flooding to the lower Mississippi Valley. Scattered showers and thunderstorms will also be possible over New Mexico and Colorado.

Meanwhile, a ridge of high pressure will continue to build over the eastern Great Lakes and the Northeast, which will keep conditions mostly clear across the region on Friday. To the south, sea breeze induced thunderstorms will pop up across parts of Florida.

In the West, monsoonal thunderstorms will develop over portions of the Intermountain West, the Great Basin and the Southwest. The strongest thunderstorms will focus over the northern Sierra Nevadas, which could lead to flash flooding in valleys adjacent to sloped terrain. A large ridge of high pressure over the eastern Pacific will keep the remainder of the West Coast clear of precipitation on Friday.
