Weather Summary

A cold front ushered in cooler and drier air to the Mid-Atlantic region on Independence Day. Readings overnight dropped into the mid and upper 50s in suburban locations, with low to mid 60s in downtown areas. High pressure will provide Baltimore and Washington with sunshine, light winds, and comfortable humidity levels on Saturday. Highs will only reach the upper 70s to around 80. However, this same high will move off the coast on Sunday, creating a more southerly flow that will result in warmer and more humid conditions. The high will continue to move out to sea during the upcoming week, sustaining the warm, humid air mass over the northeast states and setting the stage for afternoon and evening thunderstorms.
