A cold front pushed across the bay yesterday and is now clearing the area. As the front approached the bay on Saturday afternoon, a wide area of showers and thundershowers developed with some areas receiving heavy downpours. The rain showers persisted into the evening hours before giving way to a mostly cloudy sky overnight. As we move through the day on Sunday, high pressure will build over the Middle Atlantic states and provide the region with drier conditions under a mostly sunny sky. Temperatures will reach the mid 70s on Sunday, but then fall back into the 50s by Monday morning. Monday will be the first full day of autumn, and the temperature will be fitting for the season with highs only in the middle to upper 60s. By Tuesday morning, many areas will dip into the upper 40s before rebounding into the lower 70s on Tuesday afternoon.
