COLUMBIA — Much of the area was under a tornado watch Thursday evening as scattered thunderstorms threatened to batter Columbia with large hail and strong winds.
The scattered thunderstorms were expected to last until about 7 p.m., said Jayson Gosselin, a meteorologist with the National Weather Service in St. Louis.
In the western part of the state, the storm system has been accompanied by large hail, ranging in size from a quarter to a half-dollar. The hail is expected to cause damage to vehicles, according to a severe-thunderstorm warning issued by the weather service. There's also the possibility of strong winds, which could cause damage to trees and power lines in central Missouri.
Gosselin said the area could also see isolated tornadoes. Shortly after 5 p.m. Thursday, the weather service issued a tornado warning for southern Boone County and a tornado watch for most of central Missouri. The watch will remain in effect until midnight Thursday.
The potentially hazardous weather is being caused by warm, moist air mixing with a cold front, Gosselin said. The storms should weaken as the system moves into the eastern part of the state, where the air is more stable, he said.
After the storms move out of the area, the temperature is expected to drop into the mid-30s overnight, about 10 degrees below the average for this time of year, Gosselin said.
The weather is expected to improve dramatically during the weekend. The area will see temperatures in the mid-50s Saturday and the upper 60s Sunday, Gosselin said. The weekend should also be dry in the wake of Thursday's thunderstorms. The next chance of precipitation is Sunday evening.
