Forecasters say a strong low pressure system will approach the region from the west on Wednesday, touching off the storms Wednesday night and Thursday.
Damaging straight-line winds, localized flash flooding, severe hail and isolated tornadoes will be possible. Early indications suggest the line of storms will enter northwestern Alabama sometime before daybreak on Thursday, perhaps between 3 a.m. and 6 a.m. The storms will then push eastward before exiting the state by 4 p.m.
The confidence in the timing of the possible weather threat continues to increase as models become more accurate.
Changes in the forecast — including timing, threats and threat area — are possible over the next couple of days.
A Severe Thunderstorm Watch is issued when conditions are favorable for the development of thunderstorms. People in and around the watch area should keep an eye to the sky and listen to a weather radio or tune to local media for furthe information.
A Severe Thunderstorm Warning is issued when a severe thunderstorm has been detected by a national weather service doppler radar or a reliable report has been received.
A Severe Thunderstorm Warning should be treated the same as a Tornado Warning, because severe thunderstorms can produce large hail and damaging winds.
