We enjoyed a beautiful September afternoon with highs in the 70s to low 80s under full sunshine. Tonight we stay clear for the first half, with increasing clouds overnight and lows in the 50s to 60s.
A warm front will lift through New England by Wednesday morning, bringing more clouds and a spot shower across the south coast. Most of the day will then be dry, but warm and muggy in southern New England.
Scattered showers arrive in northern New England and will slowly sink southward during the afternoon and evening. A couple thunderstorms will accompany the rain along the cold frontal boundary. There is a very low risk for a strong or severe storm, but if we see one then damaging wind would be the main threat. Any storm that develops will lose steam as sunset approaches and the front moves through southeastern Massachusetts.
That cold front will help steer Hurricane Dorian away from the New England coast Friday into Saturday. New England is still out of the cone of probability for landfall, but we will still feel the effects of the storm across our area Friday into Saturday.
In fact, on Thursday southeastern New England will see some of the cloud bands from the storm as it starts to head out to sea and to the northeast.
The storm is expected to pass southeast of the benchmark. The outer bands of rain and wind will affect mainly coastal areas and Cape Cod and the islands with Nantucket feeling the most impact.
Rough seas will also bring us coastal erosion, rip currents, and some minor coastal flooding with a surge of 1-2 inches possible.
This is subject to change as we continue to track the storm movements and tighten up the forecast.
The storm moves out by the weekend, as we see sunshine and highs around 70 both days.
