Thunderstorms rolled over Arlington, Virginia, on June 20, dumping rain and letting loose booming thunder.
Heat will expand across the Northeast during the first official week of summer, with some cities likely to reach 90 degrees Fahrenheit by the middle of the week.
As the clock struck 5:43 p.m. EDT on Saturday, it officially became summer in the Northern Hemisphere.
Some more northerly locations across the Northeast began to see a heat wave build in even before it officially became summer. Caribou, Maine surpassed 95 on Thursday and Friday, more than 20 degrees above normal, and tied the city's all-time record high. Even places like Albany, New York, and Boston reached the upper 80s at the end of last week, about 10 degrees above normal for mid-June.

The heat wave that started off in Canada and northern New England will expand this week, leading to more widespread heat for the first few days of summer.
Monday, the heat that gripped northern New England and parts of the Great Lakes will expand to the remainder of the Northeast.
"Exactly how fast a wave of thunderstorms moves into these areas will determine how hot it can get on Monday west of the Appalachians," said AccuWeather Meteorologist Jake Sojda. Places from Buffalo, New York, to Columbus and Cincinnati, Ohio, may see enough clouds late on Monday to keep temperatures in the lower 80s.
But at the same time, temperatures will also be on the rise east of the mountains and along the I-95 corridor. Cities like Philadelphia, Baltimore and Washington, D.C., will make a run at 90 on Monday.
"The most sweltering heat will wait until Tuesday and Wednesday for places from Hartford, Connecticut, to Richmond, Virginia," said Sojda.
Inland locations will rise into the lower 90s, leaving residents exposed to the mid-summer heat in combination with a dose of high humidity. Some locations will be as much as 10 to 15 degrees above normal for the end of June.
At the coast, a stiff southerly wind will bring some relief. Although it will still be humid in these areas, temperatures will be capped in the 80s, albeit still above normal.
Drinking plenty of water to stay hydrated will be important for residents in order to help mitigate heat-related illnesses. Avoid doing strenuous outdoor activities during the late afternoon and if possible, complete them in the morning or evening when heat is less stifling.
Showers and thunderstorms will sweep towards the Ohio Valley on Monday, while more isolated thunderstorms pop up in the remainder of the Northeast. The more widespread wet weather and severe weather is likely across the region on Tuesday and perhaps even Wednesday.
After the midweek thunderstorms, a brief cooldown is expected to allow for a dip in temperatures into the end of the week. Still, highs are likely to still hover near or above normal. AccuWeather's long-range meteorologists forecast more 90-degree days could be in store for parts of the Northeast before the end of the month.
