Severe Weather Threat: Tallahassee, Jacksonville

A potent storm system developing in the Gulf of Mexico will spread heavy rain, thunderstorms and the risk for flooding and severe weather to much of the Southeast on Thursday.

Some locations with the greatest potential for dangerous severe thunderstorms include Tallahassee, Panama City, Lake City, Gainesville, Ocala, Jacksonville and Tampa, to name a few.

Severe storms could even make it as far north as Dothan in Alabama and Valdosta in Georgia.

The thunderstorms on Thursday will be part of the same storm system that spawned severe weather across Texas on Tuesday and Tuesday night.

In Houston, the thunderstorms produced a 63-mph wind gust downtown near the Texas Medical Center. As the storms plowed eastward, they produced hen egg-sized hail and nearly 3.00 inches of rain in Galveston.

The biggest impact from the thunderstorms on Thursday will come in the form of hail as large as ping-pong balls or even golf balls. Hail of this size can damage vegetation and crack windshields.

Damaging winds will also be a major concern with these storms as they blast through the region. In a few isolated locations, winds could gust as high as 60 mph, which could down trees and power poles.

Farther to the north, a soaking rain will drench areas from eastern Alabama across Georgia into much of the Carolinas.

Rainfall in these areas will average generally around 0.50-1.50 inches. While this isn't enough to cause major flooding, there will be some urban and poor drainage flooding in areas such as Birmingham, Ala., and Atlanta, Ga.

The rain will push into eastern North Carolina and eastern Virginia by Thursday night, where much heavier rainfall is possible.

Rainfall amounts will reach up to 2.00 to 3.00 inches across areas like Myrtle Beach, S.C. and Norfolk, Va.

This amount of rain has a better possibility of causing flooding of smaller creeks and streams, as well as low-lying areas.

If you will be out and about or vacationing along the coasts of Florida, keep a close eye on the sky. Thunderstorms will move quickly, and you should take shelter at the first hint of threatening weather.

Remember, lightning is one of Mother Nature's number one killers, and if you are close enough to a storm to hear thunder, you are close enough to be stuck by lightning.

The storms will clear the Southeast by Friday afternoon, and pleasant, sunny weather moves in just in time for the weekend.
