Forecast: Clouds Thickening Before Rain Comes In Afternoon

This article is more than 4 years old.

A coastal low pressure system will bring a windswept rain to southern New England later today through Wednesday morning. The rain will affect most areas after the evening commute Tuesday through the morning commute on Wednesday, perhaps lingering until the end of the day.

There won’t be any rain during today's daylight hours, however. You’ll likely notice some dim sunshine early this morning and then the clouds will thicken. If you are wondering where the rain is presently, it’s still stuck to our south across New Jersey. It will very slowly move north and east during the day.

This is a nor’easter storm, one in which the winds come from the northeast (which is where it gets its name). The winds will be strongest early Wednesday morning right along the coastline. There is a wind advisory posted along the coast through about sunset Wednesday, with the strongest winds blowing during the morning hours.

Winds of these speeds can cause a few scattered power issues, but I don’t expect anything widespread. The greatest risk for power problems will be on Cape Cod.

Wednesday is a holiday for many of you, but it won’t be a great day for raking leaves. Heavy morning rain will slowly taper off to showers in the afternoon. I am expecting as little as half an inch of rain, but some areas could see an inch and a half. The lightest amounts will be western and northern areas of southern New England, furthest from the storm.

Thursday is a better day in the morning, but another round of showers moves in during the afternoon and evening. These won’t be very heavy, and things will clear up by the weekend. Temperatures are also going to cool this weekend.


Today: Increasingly cloudy, slight chance of rain south towards dark. Highs in the 50s.

Tonight: Rain and becoming breezy by dawn. Lows in the 40s.

Wednesday: Rain and windy early, then cloudy with a few showers. Cool. Highs 47-53.

Thursday: Early sunshine then cloudy with a few showers. Highs 55-60.

Friday: Mostly sunny, with highs approaching 60.

Saturday: Mostly sunny, and cool. Highs 49-53.
