Another warm day is on tap Tuesday ahead of an approaching cold front that will trigger showers and thunderstorms across the region in the afternoon and evening.
Wildfire smoke from fires burning across the western U.S. and Canada will be around again Tuesday, though not nearly as bad as Monday.
High temperatures will top out in the upper 80s to near 90 degrees. Scattered showers and thunderstorms will begin to develop across western areas between 5 and 6 p.m. before moving into the Boston metro area by 8 to 9 p.m.
Due to loss of daytime heating, we're expecting the severe threat to remain diminished. Some storms may contain damaging wind gusts. A secondary round of showers and thunderstorms may develop after midnight in response to an area of low pressure developing along and behind the cold front that will be moving across southern New England.
