We are warming up in New England, with limited sunshine Saturday and a brighter day Sunday.
As humidity builds, we have equal amounts of clouds and sunshine Saturday afternoon, with the fog mostly burned off at the ocean. Temperatures are back into the 80s after a couple of very pleasant low humidity days, with wind from the south gusting past 20 mph on the south-facing beaches.

Saturday night, we will have fog returning with a low temperature near 70 degrees -- air conditioners likely be turning back on throughout the six-state region.
Fog should burn off pretty quickly Sunday except for maybe at the south coast, with a good amount of sunshine we will be well into the 80s, with low 90s likely especially across Vermont and New Hampshire.
Sunday will be day one of a heat wave that will likely last through Wednesday, and maybe even Thursday.
The front dividing hot weather here in the Northeast from cooler weather in south-central Canada has been producing flooding downpours day after day across the plains states into the Great Lakes. We get into that action beginning Monday night, when it will be especially intense, and then on and off right through the rest of the week. Each day will have temperatures in the 90s, perhaps challenging some record high temperatures, with the threat for afternoon and nighttime thunderstorms.
The temperature combined with the humidity will generate a heat index near 100 degrees Monday through Wednesday, we have a first alert for heat advisories that are likely for that time period.
