This weekend’s heat could break records. These maps show what to expect.

It’s going to get blisteringly hot in Massachusetts this weekend — potentially record-breaking hot.

Heat advisories have been issued for most locations in the state away from the coast, stretching from Saturday morning through Sunday evening, the National Weather Service said. This includes much of central and eastern Massachusetts, and some of the western portion of the state.

The advisories were put in place for “much of the region given that most locales away from the immediate coast will experience two days of heat indices in the 95 to 99 range,” forecasters said in an online discussion forum.

Take a look at what the maps show:

As temperatures soar into the mid- and upper-90s on Saturday and Sunday, they could potentially break records in communities across southern New England, forecasters said.

“Daily or even monthly record highs could be challenged,” they noted in an online forum. Here’s what that could look like:

Forecasters said Saturday night will be “especially uncomfortable with dew points in the mid to upper 60s and overnight lows struggling to fall below 70.”

There is “above average confidence” that daily or monthly record high temperatures could be challenged or broken on Saturday, the weather service said.

On Saturday afternoon, Boston will see a high of 95 degrees, according to the weather service. Most communities across the state will see afternoon temperatures in the mid-90s. The weather service is estimating highs of 96 degrees in Lawrence, 97 in Worcester, 93 in Foxborough, and 98 in Springfield.

The beach will offer a respite from the scorching heat, forecasters predicted. Coastal communities, the Cape and the Islands will be markedly cooler on Saturday, with afternoon highs only in the mid- to upper-70s.

“If you are looking to escape the heat, the coastline will offer some relief,” forecasters said.

Sunday is likely to be “another scorcher,” forecasters added.

“Given the warm start, it will not take long for [temperatures] to rise into the 90s,” they said. “It will feel a lot more uncomfortable as well, given that the dew points will be a few degrees higher than the day before.”

Highs on Sunday afternoon will reach 95 degrees in Boston, forecasters said, and most of the state will see temperatures in the mid-to-high 90s.

The weekend heat will likely not qualify as a heatwave, which is defined as three days of temperatures reaching at least 90 degrees. Still, the “anomalous heat should be taken seriously especially if you plan to spend time outdoors away from the immediate coast,” forecasters cautioned.
