Midwest, Northeast to experience hottest weather in years as temps near 100 F
AccuWeather meteorologists have all the details on how hot it will get and how long the sizzling weather will last as the region's first official heat wave of the season kicks into high gear.

"Temperatures will build to their highest marks in years across the Midwest and Northeast and stay at sizzling levels for days as #MotherNature cranks up the heat ahead of astronomical summer, which begins Thursday, June 20, at 4:50 p.m. EDT.
"AccuWeather's long-range team has been sounding the alarm for more than a week on building heat in the East during the third week of June that would put millions at the mercy of a prolonged stretch of 90-degree Fahrenheit temperatures. The longevity of the intense heat will put additional strain on residents and #ElectricalInfrastructure.
"For many in the #Midwest and #Northeast, this week will constitute the first official heat wave of the season, which, in this part of the country, is defined as three or more consecutive days of at least 90-degree temperatures. Heat alerts have been issued for more than a dozen states, stretching from #Iowa and #Illinois to #Maine, as the summer swelter takes shape."

Ancient #SolarStorm smashed Earth at wrong part of the sun's cycle — and scientists are concerned
The 9,200-year-old storm left researchers with a stark conclusion: We are not ready for the next one.

"An extremely powerful solar storm pummeled our planet 9,200 years ago, leaving permanent scars on the #ice buried deep below #Greenland and #Antarctica.
"A new study of those ancient ice samples has found that this previously unknown storm is one of the strongest outbursts of solar weather ever detected and would have crippled modern communications systems if it had hit Earth today.
"But perhaps most surprising, the massive storm appears to have hit during a #SolarMinimum, the point during the sun's 11-year cycle when solar outbursts are typically much less common, according to the study, published Jan. 11 in the journal Nature Communications. Because of this unexpected discovery, the study researchers are concerned that devastating solar storms could hit when we least expect them — and that Earth might not be prepared when the next big one arrives.
"Solar storms occur when magnetic field lines on the sun's corona (the outermost part of the sun's atmosphere) become tangled up and then violently snap back into place. This sudden magnetic reconnection can release huge gouts of plasma and magnetic field known as coronal mass ejections (CMEs), which surf across space on the sun's ever-gusting #SolarWind.
"If a powerful #CME passes over Earth, it can compress the planet's #MagneticShield, causing what's known as a #GeomagneticStorm.
"Mild geomagnetic storms can damage #satellites and interrupt radio transmissions; severe storms, like the 'Halloween storms' of 2003, can cause widespread #PowerOutages across the world and permanently damage #ElectricalInfrastructure, such as power transformers. Some researchers fear that a sufficiently large solar storm could also ravage the world's undersea internet cables, resulting in an '#InternetApocalypse' that leaves huge chunks of the world population disconnected for months.
"CME outbursts typically peak every 11 years or so, when the sun enters the part of its natural activity cycle known as the solar maximum — the time when magnetic activity in the corona is in high gear.
"Today, satellites can monitor solar outbursts directly. But finding evidence of ancient storms requires some atomic detective work. The authors of the new study looked for evidence of special particles known as #CosmogenicRadionuclides — essentially, radioactive isotopes (versions of elements) created when charged solar particles collide with elements in Earth's atmosphere.
"These radioactive particles can appear in natural records, like tree rings and ice cores. In the study, the authors looked at the latter, analyzing several cores drilled in Antarctica and Greenland. Cores from both locations showed a remarkable spike in the radionuclides beryllium-10 and chlorine-36 around 9,200 years ago, indicating that a powerful solar storm swept across Earth at that time.
"Further analysis of the cores showed that the storm was particularly powerful — perhaps on a par with the most powerful solar storm ever detected, which occurred during a solar maximum between the years 775 B.C. and 774 B.C.
"The newly discovered storm's occurrence during a solar minimum, when magnetic activity on the sun should be low, left the study authors puzzled and alarmed.
"'This [storm] further pushes the magnitude of a potential worst-case scenario for [solar storm] events,' the researchers wrote in the study.
"According to the study authors, it is now essential for researchers to detect more ancient, extreme storms in the ice-core and tree-ring records, to determine if there is some sort of pattern beyond the sun's 11-year cycle that dictates when the most extreme storms will occur."
