BOSTON — As warm and very humid air attempts to move north Friday, there is a chance of showers and even thunder across the region. It is currently unclear how long the showers will last and if there will be a break in the action Friday afternoon.
Most models agree the front will make it into southern New England, but then stop somewhere around the Massachusetts Turnpike. If the front lifts further north, you will notice some brightening in Boston later on Friday, and it will become quite warm and humid. However, if the front stalls south of your area, it will remain damp and muggy, but not very warm all day.
Overnight more showers and the chance of storms resumes due to the cold front moving in from the west. The timing of the front is such that we will have a round of showers in the morning followed by clearing in the afternoon.
Right now Sunday looks nice and sunny with highs in the upper 70s inland and cooler along the coast.
There is one potential problem to the entire forecast this weekend. As the front pushes offshore on Saturday evening it will slow down. If the front slows too much, the forecast will dramatically change for Sunday with clouds and showers coming in, especially at the coast.
Warmer and drier weather arrives early next week.
Friday: Muggy with showers, highs from 66 to 72. Warmer on the south coast and interior south west Massachusetts.
Friday night: A few showers and perhaps a thunderstorm late at night. Lows from 62 to 66.
Saturday: A few morning showers and a possible thunderstorm. Skies clear west of Route 495 early, but clouds could linger much of the day over eastern areas and Cape Cod. Highs in the 70s.
Sunday: Sunny inland, but partly sunny along the coast. Highs from 75 to 80.
Monday: Sunny, with a high in the upper 70s inland and mid-80s on the coast.
