Heavy downpours marched across the state Thursday into the Boston area, prompting forecasters to warn of reduced visibility and possible flooding of poor drainage areas.
As of about 3:30 p.m., National Weather Service radar showed storms stretching from Southcentral Massachusetts through Boston’s western suburbs to the Merrimack Valley and North Shore, moving east.
“Brief but heavy downpours have been observed in this line,” the weather service said in a special weather statement that included the Boston area. “Do not drive through flooded roads or underpasses. Avoid low lying areas near small streams.”
On Friday, there will be a chance of showers in the late afternoon and evening; otherwise it will be mostly sunny in the Boston area, with a high near 86, forecasters said.
“More showers and isolated thunderstorms are possible,” forecasters said. “The more sunshine we get Friday morning, the stronger any storms could be in the afternoon.”
Forecasters said “very humid conditions” will continue into the weekend, with a chance of showers Friday night and thunderstorms possible after 1 a.m., forecasters said.
The high humidity is expected to continue through Saturday with areas of showers and a few thunderstorms, and then a cold front should bring us some much-needed relief.
We can look forward to a dry spell Sunday and Monday, and starting off the workweek with “mild and more comfortable conditions,” forecasters said. Sunday and Monday should be mostly sunny, with high temperatures reaching the low- to mid-80s, forecasters said.
But the sunshine won’t last very long. Forecasters expect more rain and humidity to return by the middle of next week.
[5 am] morning showers give way to partial sunshine followed by a round of showers and embedded thunderstorms this afternoon from west to east. Here is one model simulation (HRW NSSL) of what the radar may look like this afternoon. Very warm and humid conditions continue. #MA #RI pic.twitter.com/I9qtg53M7l— NWS Boston (@NWSBoston) July 26, 2018
