Severe thunderstorms are possible in parts of the Southern Plains and Lower Mississippi Valley, including in the path of totality. Millions more are expected to travel for Monday’s eclipse as the path of totality will be 40 to 50 miles wider than 2017’s path. This could potentially lead to an increase in cloud cover in both regions and could obstruct totality views. CNN Weather CNN Weather Two forecast models show where clouds could be during the eclipse Monday afternoon. More precise cloud cover forecasts with higher confidence levels should be possible by this weekend.
