Synopsis: A weak low pressure system will approach the area during the remainder of the weekend. A northerly swell may also move into the Atlantic waters by early week. Shower and thunderstorm chances will increase through early next week with the arrival of the low pressure. With deep tropical moisture around, expect continued diurnally driven convection through much of the upcoming workweek. Locally higher winds and seas can be expected with strongest activity as well as cloud-to-water lightning and perhaps a few waterspouts.
