LITTLE ROCK, AR - A tornado watch covers almost all of Arkansas as a storm system begins its march across the state.
The National Weather Service has already issued one tornado warning that includes Ashley County. That warning expired at 3:30 p.m.
The brunt of the storm system is still in far western Arkansas, where a cold front is meeting warm, moist air that has been blowing from the south. A number of severe thunderstorm warnings have been posted for northwest Arkansas. The National Weather Service says hail an inch in diameter was reported this afternoon in Johnson and Logan counties by storm spotters.
The weather service says that conditions are ripe for formation of supercell thunderstorms and possible strong tornadoes. Forecasters advise people to stay informed of changing conditions.
