The weather forecast includes severe weather warnings for Sunday night and possibly freezing temperatures by Tuesday morning. High pressure is in control across Southeast Louisiana and South Mississippi, allowing temperatures to reach the upper 70s to lower 80s for afternoon highs. However, a cold front is expected to arrive from the west, leading to a line of showers and thunderstorms ahead of the front. These storms could pose a significant threat to the north, particularly for sensitive plants that have started to grow during this period. The weather forecast is also expected to be followed by a significant cool-down to the start of the week.
