CHARLESTON, S.C. (WCIV) – Many weather experts spent thelast week of January were bracing for severe weather for much of the Southeast.A strong cold front was making its way from southeast Texas and taking a run tothe East Coast.
Unseasonably warm, moist air was ahead of the cold frontwith temperatures 15 to 20 degrees above normal. On the back side of the coldfront were temperatures well below normal.
On Wednesday morning in Charleston, temperatures were 18degrees warmer than just one day earlier. As the cold front made its way intothe southeast, it brought plenty of wind along with cooler temperatures.
And yet less than a tenth of an inch of rain fell in NorthCharleston.
Winds were strong enough to bring out more than 30 stormreports for the Palmetto State. Most of the damage was caused by strong windsthat brought down trees and power lines. One hail report was reported in the Upstate.
And talk about a temperature change, reports from Atlanta mademention of a drop of 35 degrees from between Wednesday and Thursday morning.The actual temperature in Atlanta at 9 a.m. was 33 degrees.
Cold fronts can bring in that huge difference in temperature.The temperature difference across a cold front boundary can be as much as 54degrees. If moisture is present, then rain will occur. If instability ispresent in the atmosphere then thunderstorms may be present as well. Theeffects from cold fronts may last several hours or several days.
That band of precipitation that follows along the leadingedge of the cold front may become strong in nature producing severethunderstorms. Severe thunderstorms are capable of producing winds greater than58 mph and or with inch-size hail. Tornadoes also may be present during severethunderstorms.
Many times here in the Lowcountry we'll see an unannouncedcold front move through the area. An unannounced cold front means there may bea slight change in wind direction without clouds, precipitation or temperaturedrop.
