Boston weather forecast calls for heavy rain, thunderstorms and localized flooding Monday
The WBZ-TV NEXT Weather Team is issuing a NEXT Weather Alert for rounds of heavy rain through Monday in the Boston area.
A cold front will bring some heavy rain and gusty winds, along with some isolated thunderstorms.

While widespread flooding looks unlikely, the system will carry a lot of moisture with some localized flooding possible, especially if any areas get multiple downpours. Total rainfall amounts will range from a quarter of an inch to up to 2 inches of rain. There may be isolated amounts of 2 to 4 inches of rain in spots.
Right now, it looks like the highest totals will be across central and western Massachusetts, with lower totals across southeast Mass.
Gusty winds will also be with us through the day with gusts over 30 mph possible, first out of the south, and then shifting out of the west and northwest once the front comes through Monday evening.
Showers and downpours will be on and off throughout most of the day Monday. Any showers or storms could bring quick downpours, making driving difficult and leading to some minor street flooding, especially in any urban and poor drainage areas. That was the case in Fitchburg, Lunenburg and other parts of Worcester County Monday morning.
There is a chance of one final line of storms Monday afternoon and evening along the edge of a cold front.
These will largely be driven by how much sunshine develops today - the more sunshine the greater the fuel for any late day storms.
The greatest risk of a downpour or severe storms would be across central and western Massachusetts.
The good news is it's a fast-moving system, with clearing skies late Monday evening, and a return to the sunshine for Tuesday.
The humidity looks to stick around and with a rise in temperatures through the week, unsettled conditions return with the chance of a pop-up shower or storm mid to late week. This shower risk will coincide with heat index values climbing into the mid to upper 90s. As always, the WBZ Next Weather Team will continue to keep you prepared and will update you on air and online with any changes to the forecast.
