There will be a dramatic start to April in midwestern and southern parts of the US, with an influx of warm moist air from the Gulf of Mexico fuelling severe thunderstorms through the first part of this week.
On Monday, storms are forecast to stretch from Texas towards the Great Lakes, with Oklahoma, Missouri and Illinois expected to be most severely affected. The system will then move eastwards on Tuesday, with Kentucky, Tennessee and Ohio expected to receive the greatest impact.
