An earlier story follows:
Each day this week seems to have outdone the previous as far as thunderstorm activity goes.
Hundreds of reports of damage from trees being broken by wind, to flooding, to lightning strikes, and perhaps a tornado or two all occurred from noon through sunset Friday.
Saturday picks right up where we just left off. Although it shouldn't be as hot, the storms are going to be widespread with heavy rain and flash flooding likely.
The ground is saturated in much of southern Vermont, southern New Hampshire, and central and western Massachusetts. With another two to four inches of rain possible, flooding may be the biggest issue of the day.
Showers and storms start the day in an arc from north-central Maine through central New Hampshire, and much of Vermont through central Massachusetts and Connecticut first thing in the morning. The arc then contracts and moves east and south as the day goes on. Perhaps some of the Pan-Mass bicyclists will make it to the Cape Cod Canal ahead of the rain.
Rain moves into southeastern New England after two in the afternoon, and then to Cape Cod by evening.
Rainfall in excess of three inches is likely, with possible damaging thunderstorms, as well.
We'll see partial clearing overnight, with temperatures cooling to the 60s in Western New England, but remaining sticky with a low in the 70s east.
Sunday is by far the pick of the weekend with partly to mostly sunny skies and a high temperature back to near 90 degrees, but humidity will be down a notch.
Monday looks similar, close to 90 degrees. Then Tuesday is also near 90 degrees, but thunderstorms come back, leading to a slight cooling trend for the second half of next week.
