Forecast: Early Morning Showers And Thunderstorms, Clear Afternoon

This article is more than 5 years old.

A very vigorous system for early October is moving through the area this morning bringing showers and thunderstorms and slowing down the morning commute. These storms are coming up from the south and are part of a system which brought severe weather to the mid-Atlantic region earlier Tuesday night. This is a very fast moving system and as such will be gone between 8 and 10 a.m. depending on where you live.

There is a small chance of severe weather and even a spin-up of a weak tornado, but this is the exception to the general downpours this morning. This afternoon skies will clear and it will be quite nice with above normal temperature readings around the 70 degree mark.

Thursday brings more sunshine, but cooler readings with highs only around 60 degrees. The air will also feel much drier with low levels of humidity.

More changes come Friday as a weather system moves to our south. The exact track of this system will determine if the rain shield comes to Boston, stays south over Cape Cod or less likely reaches the border towns of New Hampshire.

Friday does look like a transitional day as that storm gathers in the Ohio Valley and moves to the mid-Atlantic coastline. As the system gets closer, clouds will increase in the afternoon, but I don't expect any rain until late at night.

Saturday is the big question mark for the weekend. Sunday is sunny, cool and dry, but Saturday could end up wet in the morning or just cloudy. We’ll have to wait another day to gain more confidence in the start of the holiday weekend forecast.

Today: Showers and thunderstorms before 10 a.m. Some of the storms could produce gusty winds and heavy rain, but becoming mostly sunny in the afternoon with high near 72. Gusty winds could cause scattered power issues and downed trees.

Overnight: Mostly clear, with lows in the mid 40s but breezy.

Thursday: Sunny with a high in the lower 60s.

Friday: Sunshine followed by increasing clouds with highs in the mid 60s.

Saturday: Morning showers possible but clearing north to south in the afternoon with highs in the lower 60s.

Sunday: Mostly sunny with a high between 57 and 61 degrees.
