Summer is upon us, the temperatures will show it!

BOSTON (WHDH) -- With temperatures expected to reach the low 100s and upper 90s this week, Massachusetts is taking steps to combat the heat and urging residents to stay cool.
According to the National Weather Service, temperatures in Boston could be around 100 degrees on Wednesday and Thursday, breaking records for those dates. With the heat comes high levels of humidity.
Summer starts at 7:09 p.m. Wednesday and it’ll feel like it. It’s expected to be hazy, hot and humid with highs in the mid to upper 90s and heat indexes well over 100.
Thursday will be similar…Hazy, hot and humid with highs in the 90s and isolated pop-up thunderstorms during the late evening hours. If winds stay light out of the west, a minor sea breeze could kick in lowering coast temperatures to 90 degrees.
On Friday highs will still be near 90 degrees. There will be a hazy sunshine and a chance of a few pop-up storms in the afternoon and evening.
Boston could see a heat wave, which is three consecutive days of 90-plus degrees.
In Boston, water spray features and air conditioned community centers will be in operation throughout the day, offering residents opportunities to keep themselves cool. State Department of Conservation and Recreation-run beaches will also be staffed with lifeguards.
The Massachusetts Emergency Management Agency has issued a list of precautions state residents should take to avoid heat exhaustion and other health issues.
