When there is a high pressure air mass in your area, the weather is typically sunny and dry, with few or no clouds in the sky. High pressure systems are associated with sinking air, which causes the air to warm and dry out as it descends. This inhibits the formation of clouds and precipitation, resulting in clear skies and dry weather conditions. Additionally, high pressure systems tend to bring cooler temperatures, especially at night, due to the clear skies allowing heat to escape into space.
