The How

A strong passing low pressure system will not only trigger rain showers, but also the instability in the atmosphere will also be enough to spark some thunderstorms. Saturday, a cold front will follow, causing another day of rain showers with some cooler temperatures. Sunday a high pressure system will dry skies out, but a further cool down is expected.
