We have our first tropical system of the season in the Atlantic…Tropical Storm Andrea has formed in the Gulf and will impact every State on the East Coast by the weekend. The wind won’t be the issue but the moisture will. Heavy rain will spread up the East Coast Friday into Friday night and drench Southern New England with 1-3″ of rain.
Tomorrow will be a dry day with some sun to be had in the morning but with a frontal boundary draped to our north in the afternoon, clouds will increase and showers will break out in Northern New England in the afternoon. A trough will dig into the East Coast from the Great Lakes grabbing the remnants of Andrea and slingshot them north Thursday night. Moisture from the northern flank of the system will get rung out by the stalled front over New England leading to showers Thursday night and Friday morning. By Friday afternoon, some of the deep tropical moisture will overrun the area…this will result in the heaviest and the steadiest of the rain falling in the afternoon. Friday night, the core of the remnants reaches Southern New England and very heavy rain can be expected…1-3″ of rain looks likely and some temporary street flooding will occur. The system will be fast-moving and out of here by Saturday morning but the upper-level system will be hanging back over us. This will lead to quite a bit of cloud cover and even a few passing showers but most of the weekend appears to be rain-free…just not cloud-free.
