High pressure which has provided the Middle Atlantic states with sunny, pleasant weather over the last couple of days will move east today. The clockwise flow around the high will bring in a southerly, slightly more humid flow of air. Nonetheless, a mostly sunny day is expected on Friday with highs in the low to mid 80s. There may be a few fair-weather clouds from time to time, but no precipitation is expected. Meanwhile, low pressure entering the Gulf of Mexico will begin to impact our area with clouds moving in by early Saturday morning. At the moment, it looks as though the first half of Saturday will remain dry, with showers moving in later in the day and during the evening. Eventually, the low will nudge high pressure to the northeast and will produce more widespread showers on Sunday, although the rain will not be particularly heavy. The clouds and precipitation will hold temperatures down in the middle 70s over the weekend with overnight lows in the mid to upper 60s. Showers may persist into Monday morning, to be followed by a more summer-like pattern as highs next week rebound into the mid to upper 80s.
