With the rain and clouds in place, temperatures will max out in the lower to perhaps middle 70’s across the region which is about 6-to-10 degrees below the average for this date. So it is a slight bump in the road in what has been a spectacular week and especially awesome for the many folks on vacation.

There is only a slight risk of a bit of lightning and thunder on the South Coast and Cape Cod Friday but there is a marginal risk of a few spotty severe thunderstorms Saturday across most of the region as a cold front approaches from the west.

The predicted available parameters suggest a few of these storms could produce large hail and damaging wind.

If any severe weather develops Saturday, stay with WBZ-TV, WBZ NewsRadio 1030 and CBS Boston.com for updates.
