Weak high pressure along with a southerly flow of air will keep weather conditions warm and moderately humid over the Greater Boston area through Saturday.
A front to the west will cause a line of thunderstorms to develop over eastern New York this afternoon and track eastward.
Some of storms could be severe in Western Mass. and across Connecticut. However, they should be in the diminishing stages as they reach the Boston area early tonight.
Similar humid conditions with partly cloudy skies can be expected Thursday and Friday. A stronger front will cross Saturday with the risk for scattered thunderstorms.
Skies will clear on Sunday, with cooler, much drier air moving into the region.
