Explained in plain English
What is a low pressure system?
The story mentions a 'band of low pressure' bringing the rain. This is an area where the atmospheric pressure is lower than its surroundings. Air rises in these systems, cools, and forms clouds and precipitation. This is why low pressure often means unsettled, rainy weather, as we're seeing this weekend.
