COLUMBIA, SC (WIS) - Severe thunderstorm watches have been issued for several counties across South Carolina Tuesday afternoon.
The Severe Storms Prediction Center indicates severe thunderstorms will return to the area late this afternoon and this evening. The threat of thunderstorms across the Midlands is high, with ingredients in place for some to produce damaging winds, hail and an isolated tornado.
While the weather has remained quiet, daytime heating combined with a disturbance in the upper atmosphere will be the trigger for severe weather. There is a strong disturbance now in Tennessee heading eastward. The weather system is stronger than on Monday, and is expected to arrive later in the day than Monday's storms.
A severe thunderstorm watch means conditions are favorable for the development of severe thunderstorms over a large geographical area. A severe thunderstorm warning means "take action," and is issued for localized areas when severe thunderstorms are threatening.
Thunderstorms are dropping 2-3 inches of rain and creating standing water problems on some roads.
Look for storms to diminish after dinner, but until then there will be more heavy rainfall with gusty winds and dangerous lightning. Patchy fog should develop after the storms. Wednesday's forecast calls for mostly cloudy skies with more showers and thunderstorms as a weak cold front moves east. By the weekend, the skies should clear with less shower activity.
