A quick-moving storm moved out of Somervell County as expected Friday afternoon, but a thunderstorm warning remains in effect.

A notification sent out by National Weather Service (NWS) Fort Worth at 1:20 p.m. Friday said the warning would remain in effect for about an hour.

Like clockwork, the storm moved in, dumped rain on parts of the county and moved on.

NWS requested spotter activation in Somervell County at about 1:30 p.m., saying ping pong ball-sized hail and winds of up to 50 mph had hit the southern portion of neighboring Erath County.

A severe thunderstorm warning means that a severe thunderstorm is occurring or is imminent based on doppler radar information.

Meanwhile, the severe thunderstorm watch - in effect until 7 p.m. Friday - means that the potential exists for the development of thunderstorms that could produce large hail or damaging winds.

Residents are advised to keep an eye to the sky and an ear to the National Weather Service's weather radio or local radio and television stations for further updates and possible warnings.
