Strong high pressure will remain anchored off coastal New England through Thursday. This feature will create gradually increasing onshore winds and building seas across our local waters, with Caution conditions expected tonight and then Small Craft Advisory conditions developing on Tuesday or Tuesday evening. Meanwhile, a trough situated to the northeast of the Bahamas will be steered westward towards the southeastern seaboard late this week, with weak low pressure possibly developing as this system traverses the Gulf Stream waters. Showers and thunderstorms will increase beginning around midweek, with activity likely continuing into the upcoming weekend. High pressure will then weaken as it sinks slowly southward towards Bermuda, with the axis of this surface ridge extending across our area during the upcoming weekend. Winds and seas will gradually diminish as prevailing winds shift to southeasterly on Saturday and then southerly by Sunday. .GULF STREAM...
