A persistent southerly flow of air has pumped humid air northward into the region, resulting in an abundance of low clouds and fog here on the Cape and Islands over the last couple of days. The southerly wind and early season muggy air flowing northward over the still cool ocean waters surrounding the area is a recipe for murky weather.
Thankfully, a frontal zone is approaching the region from the west and that boundary will slip offshore today. Behind the front, drier air is pushing eastward and that drier air will gradually shift onto the coastal plain over the course of the day today and into tonight, meaning lowering humidity and clearing skies.
With that in mind, our gray damp start to the day (which includes a few passing showers/downpours scattered about the area) will give way to brightening midday skies and developing sunshine over course of the afternoon.
Expect temperatures to climb into the 70s and a gusty southwest wind to persist throughout the day.
