America’s 250th birthday also marks the final stretch of one of the most intense eastern US heat waves in years — one made worse by climate change — and it could fuel an added storm threat as the nation gathers to celebrate.

Dangerous heat is on the guest list at every Fourth of July celebration in the region, with high temperatures in the 90s and low 100s forecast from New England into the Southeast. Saturday will likely be the third day in a row of triple-digit temperatures for major metros like Philadelphia and Washington, DC. At least 22 locations broke or tied daily temperature records Thursday and 17 more fell Friday. Here are some headlines from the heat wave:

• Heat-related illness and death: A 68-year old man died after trimming bushes on July 2 in Bethel Township, Pennsylvania, where high temperatures passed 100 degrees, the Berks County Coroner’s Office told CNN. The cause of death was a heart attack from strain “due to heat exhaustion,” the office said. Meanwhile, the CDC reported “extremely high rates of heat-related illness” in regions across the Northeast on Thursday.

• Events canceled or delayed: The July Fourth parade set for Saturday morning in Washington, DC, was canceled due to extreme heat in the nation’s capital. President Donald Trump’s Great American State Fair is opening two hours late at 12 p.m.

• NYC power outages: Thousands of customers in the New York metro area were without power Friday and Saturday morning, according to local utility Con Edison. Some of the outages were shutdowns to prevent extended outages. Voltage reductions were also happening earlier in the day in parts of Staten Island, Queens, the Bronx, Brooklyn and Westchester, Con Edison spokesperson Jamie McShane told CNN.

2. This is starting to sound Biblical, Old testament style

It feels like so many of his plans and choices are backfiring in ways beyond his control.

He must be very frustrated right now as even his perceived power is eluding him. He wants to control everything and everyone, but apparently the weather isn't impressed.

3. Anyone older than 20 years old can remember when our summer days were bearable

But there's no such thing as global warming.

4. And their electrical grid is strained to the max

The largest electrical grid in the country contains the Washington DC and Virginia Area......

The shortage of electrical power certainly can't possibly be because of the 450? AI Server Farms in Virginia?????????

5. Friday was the hottest day I can remember in this rural KS town wherein I live.

Then I got woke up very early in the morning today to a huge thunderstorm. At first, I thought it was one of those super M80/M100 fireworks, or whatever they call them. They're so loud they shake the house! But no... THIS was thunder! This was Mother Nature sending us a reminder than nothing can out do She, Herself! It rained buckets for hours, with the accompanying bolts of lightning and huge booms of thunder. My cats didn't care WHAT made it... they just hated the noise, and so did the dogs. Gave him a couple more of the calming herbals and held the cats tighter. It finally stopped raining about 4pm today, and the temp was actually pleasant, 70 degrees... which just means the fireworks will get cranked up full throttle later on tonight. (SMDH) You can't win for losing, my poor babies. And I weep for all the poor babies out on their own through all of this. May Bast watch over them all and keep them safe.
