A coastal storm, developing as a result of a powerful mid and upper level system, developed today from the Delaware Coast to a position off the coast of the Mid-Atlantic states. Heavy rain moved through much of the area as a result of an inverted trough, and shifted from north to south throughout the day as the surface low moved more seaward. Since then, precipitation has become much more showery in nature — absent are the areas of heavy rain and thunderstorms. Northeasterly winds have increased in intensity along the coast.
Through the evening, the surface low off the coast is expected to strengthen slightly as the mid and upper level systems move south of Long Island. In a form more typical to winter-time systems, the surface low may actually hook back westward later tonight. While the storm itself isn’t necessarily strong in regards to its central pressure, the gradient between the developing surface low and the higher pressures around it will aid in the development of strengthening surface winds, especially along the coast.
