High pressure has anchored itself over the northeastern part of the country and our nice weather that began yesterday will continue right through tomorrow. This weekend, however, will see the high pressure shift off the east coast and a low pressure area will develop just off the Mid-Atlantic coastline by later in the weekend. As a result, clouds should increase around here tomorrow night and the threat for showers will return for Saturday and Sunday and perhaps even for Monday as well. Temperatures should generally remain on the cool side of normal right through the weekend, but there will be a warmup next week.
Elsewhere, the tropics are getting more and more active just as the climatological peak has arrived (mid-August through September). One disturbance over the northwest Caribbean Sea could cross the Yucatan Peninsula and head into the Gulf of Mexico during the next few days. This system could ultimately bring heavy rainfall anywhere from the central Gulf coastal region to northeastern Mexico in the next several days and it is not out of the question that some of this moisture eventually makes it up the east coast. A second system of interest that moved off the west coast of Africa only recently has intensified quickly into Tropical Storm Erin. This system will encounter some dry air as it treks to the west-northwest across the tropical Atlantic over the next few days.
