On May 6th to 7th, 2020, three air pressure systems were located around Salem, Oregon. The first system was a low-pressure system situated to the southwest of Salem, bringing in cooler and potentially wet weather to the region. The second system was a high-pressure system positioned to the northeast of Salem, resulting in clear skies and warmer temperatures. Finally, a ridge of high pressure was building over the Pacific Northwest, creating stable and calm conditions over Salem during this time period. Overall, these three air pressure systems contributed to a mix of weather patterns in the Salem area, from cooler and wetter conditions to warm and clear weather.
