Severe storms are also possible from south central Texas in the mid-Mississippi Valley.
Across parts of southeast Oklahoma into central and northeast Texas, the NWS said thunderstorms are expected to develop ahead of a cold front by the midday.
"The NWS storm prediction center in Norman, OK, is forecasting the development of a few strong tornadoes ... and scattered to widespread damaging winds/large hail over parts of the southern plains and Arklatex this afternoon and tonight," according to a news release.
During the evening hours, Louisiana and Arkansas can expect the same storm system that could be capable of producing large-damaging hail, strong winds and tornadoes.
A squall line is expected in these storms as they approach Louisiana and Arkansas, increasing the threat of strong damaging winds in the evening hours.
Within seconds, a tornado can cause fatalities and devastate a neighborhood. It's important to be well prepared before one hits.
Learn about any tornado warning system in your county or locality. Many tornado-prone areas have a siren system. Know how to distinguish between the siren's warnings for a tornado watch and a tornado warning.
A tornado watch is issued when weather conditions favor the formation of tornadoes, for example, during a severe thunderstorm.
During a tornado watch, stay tuned to local radio and TV stations or a National Oceanographic and Atmospheric Administration weather radio for further information.
Watch the weather and be prepared to take shelter immediately if conditions worsen.
A tornado warning is issued when a tornado funnel is sighted or indicated by weather radar.
If a warning is issued, take shelter immediately.
Because tornadoes often accompany thunderstorms, pay close attention to changing weather conditions when there is a severe thunderstorm watch or warning.
A severe thunderstorm watch means severe thunderstorms are possible in your area. A severe thunderstorm warning means severe thunderstorms are occurring in your area.
