Hottest weather of season on tap for Northeast as record-challenging heat wave builds

As a heat wave expands over much of the eastern two-thirds of the nation, the northeastern United States will share in the summer swelter with record highs, the hottest weather so far in 2019, and AccuWeather RealFeel® Temperatures well above 100 F.

While temperatures may be briefly held back in areas that receive a thorough drenching as Barry moves through into Thursday, intense July sunshine, combined with a northward retreat of the jet stream will allow an impressive heat wave to build even for midsummer standards.

In the northern U.S., a heat wave is generally that which brings three or more days in a row with highs of 90 F.

“The combination of sunshine, temperature, humidity levels and other factors will push AccuWeather RealFeel® Temperatures well into the danger level past 105 degrees during the late morning and afternoon hours,” according to AccuWeather Senior Meteorologist Brett Anderson.

Hello, Summer! Today’s Solstice Marks Season’s Beginning | Space

Summer will officially arrive in the Northern Hemisphere today (June 21), marking the longest day, the shortest night and the beginning of summer.

The June solstice will occur at 11:54 a.m. EDT (1554 GMT), as the sun reaches the point at which it is farthest north of the celestial equator. To be more precise, when the solstice occurs, the sun will appear to shine directly overhead for a viewer stationed on the Tropic of Cancer (latitude 23.5 degrees north) in the western Atlantic Ocean, roughly 600 miles (965 kilometers) to the northwest of San Juan, Puerto Rico.

From midnorthern latitudes, we can never see the sun directly overhead, but the same principle holds. For example, as seen from Philadelphia at 1:02 p.m. EDT on solstice day, the sun will attain its highest point in the sky for this entire year, standing 74 degrees above the southern horizon.

To gauge how high that is, your clenched fist held at arm’s length measures roughly 10 degrees, so from the City of Brotherly Love, the sun will appear to climb more than “seven fists” above the southern horizon. And since the sun will appear to describe such a high arc across the sky, daylight will be at its longest extreme, lasting 15 hours and 1 minute.

LIGHTNING STRIKES PENNSYLVANIA: Cases of people struck by lightning in Pa. not as uncommon as you might think | WPXI

A number of people have been struck by lightning in Pennsylvania in the last few years, most recently Thursday when two 18-year-olds were killed.

a lightning strike in Mammoth Park in Mount Pleasant while they were fishing. Both had just graduated from high school.

In August 2018, a 45-year-old man was struck by lightning while playing soccer in Pittsburgh’s Schenley Park. Bystanders performed CPR on him until paramedics arrived and resuscitated him.
