A persistent area of low pressure continues to plague the Middle Atlantic states with heavy rain showers and gusty winds. The low will produce additional rainfall tonight and through the day on Saturday before weakening and moving out to sea on Sunday. Daytime temperatures will hold in the 60s with overnight lows in the 50s. Additional rainfall amounts of up to 1/2 inch can be expected from Friday night through Saturday night. Heavier showers falling on already-saturated ground may result in areas of flooding. In addition, strong winds from the north may cause coastal flooding at some locations around the Chesapeake. The extended outlook calls for improving conditions on Monday and Tuesday with areas of morning fog giving way to afternoon clouds and sun. The high each day will range from the upper 60s to lower 70s with overnight lows in the mid to upper 50s.
