BOSTON — Be careful: As a heat wave that has gripped much of the nation's center moves East, Massachusetts is in for a couple of scorching days.

That's the word from local government and weather officials who are advising people to take precautions against temperatures that could feel as hot as 105 degrees Fahrenheit on Thursday.

A map issued by the NWS shows parts of Massachusetts affected by an "excessive heat watch."

The National Weather Service put an excessive heat watch advisory for much of the Northeast in effect for Thursday and Friday. Meteorologist Alan Dunham a rising dewpoint is what will make Thursday it will feel so hot.

"We have the high temperatures and the extra moisture in the air — it's going to make it feel hotter. Heat index values for the area will be up over 100 for both Thursday and Friday, specifically looking between 100 and 105," Dunham said.

Wind gusts as high as 30 miles per hour could make Thursday feel especially fiery. "It'll be kind of like walking in a blast furnace out there. Only a muggy blast furnace," Dunham said.

Mayor Thomas M. Menino issued a heat advisory for Boston and said the city's cooling centers and pools would extend operations until 9 p.m. (Click here for a full list).

“In these conditions, we must remember to stay cool and hydrated and continue to keep an eye on our neighbors,” Menino stated.

Dunham said young children, the elderly and individuals with respiratory problems should stay indoors, in temperature-controlled environments, as much as possible.

He said the high heat and humidity is only expected to last through Friday. Saturday's temperatures could still be in the 90s, but the humidity will have dropped; for Sunday, he predicted temperatures in the 80s and low humidity. "
