"Northwest U.S., British Columbia brace for historic, record-melting heat"

"A shockingly intense heat wave for the location, and for so early in the year, will produce some of the highest readings ever observed across much of the Northwest U.S. and adjacent southwest Canada. Temperatures will soar to dangerous levels – well above 100 degrees Fahrenheit in many places – from Friday, June 25, into the following week, in a region where hundreds of thousands of residents lack central air conditioning or any AC at all. For several days, multiple computer forecast models have been spitting out astonishing numbers for Portland, Oregon; Seattle and Spokane, Washington; Vancouver, British Columbia; and other towns and cities. Even with some potential model overestimation, confidence is growing that a truly historic heat wave is on tap. One sign of this is official forecasts from the National Weather Service: They've grown bolder through the week as model agreement has solidified and the event has drawn closer. As of midday Thursday, June 24, the National Weather Service forecast was calling for Spokane to hit 110°F on both Monday and Tuesday, June 28 and 29. These would break the city's all-time high of 108°F from July 26, 1928, and August 4, 1961. In Portland, Sunday is predicted by the National Weather Service to be the hottest day in city history. The forecast high of 109°F would topple the all-time record of 107°F set on July 30, 1965, as well as August 8 and 10, 1981."

"Extensive & Life-Threatening Heat Wave For The Western US"

  • An extensive and life-threatening heat wave will set up in the Western US this weekend and into next week.
  • This potentially historic heat wave will break many records with all-time record highs in jeopardy as well.
  • Do not underestimate the dangerousness of this long duration event. Again, this could be a life-threatening event, especially for sensitive populations.

Excessive Heat Watches/Warnings/Advisories

Excessive Heat Watches, Warnings and Advisories have been posted up and down the Western US in advance of the dangerous heat wave that will begin to intensify as we head into the weekend and lingering into much of next week. Locations in the heat headlines include, Washington, Oregon, Idaho, Montana, California and Nevada.

What: Temperatures are already well above normal. Heat will continue to build to potentially dangerous to life threatening levels as high pressure builds. There is potential for all-time record high temperatures in some areas. So that means some may experience highs never before felt in the region. Those without adequate access to cooling or proper hydration will be at particularly high risk for heat-related illnesses like heat exhaustion or heat stroke.

When: Generally from Friday through Monday. In some areas, the heat wave may last as late as Thursday of next week.

Heat Waves Are Trending Hotter Over Time
By Paul Douglas

Unlike tornadoes, hurricanes and floods, heatwaves are often invisible tragedies. NOAA says extreme heat is America's biggest weather-killer. A 2020 study of 297 counties across the US from 1997-2006 showed an average of 5600 heat-related deaths every year, significantly more than previously thought.

A warming atmosphere is making the hottest days 3-5F warmer than they would be in a world where CO2 levels hadn't doubled. The frequency of heat waves has tripled in a generation.

All-time record highs may be set in Seattle (103F in 2009) and Portland (107F in 1981) Sunday and Monday, with temperatures 35-50F warmer than average into British Columbia, which is extraordinary.

A stalled storm over the Midwest will keep a few showers and T-storms in our forecast into much of next week. Heaviest rains may fall near the Iowa border (where severe drought is setting in) and models print out an inch of rain over the next week.

We get a break from the heat: 70sand 80s until further notice. We can handle that.

What's in the Night Sky?

Moon, Jupiter, Saturn late night to dawn

On the last nights of June 2021, watch for three worlds in space: the moon, Jupiter, Saturn. The waning gibbous moon is past full on these nights. It's rising later in the evening or after midnight. On June 25, Saturn follows the moon into the sky by roughly an hour. Jupiter follows an hour or so after Saturn. But the moon is moving, always, toward the east in orbit around Earth. As a result, the moon rises an average 50 minutes later each night. So the moon catches up to Saturn and then Jupiter. On the night of June 26 (morning of June 27), the moon is near Saturn in the sky. By the night of June 27, the moon rises in between Jupiter and Saturn. And so it goes, as the evenings pass, with the moon shifting continually toward the east.

Climate Stories

"High stakes and high stress, forecasting tornadoes can take psychological toll"

"Tornadoes can have profound effects on meteorologists who issue warnings for them, especially when lives are lost. Chris Darden had just told his wife to take shelter from the tornado headed toward their home in Madison, Ala., when the phone call dropped. The violent storms bearing down on the state on April 27, 2011, were triggering widespread power outages, causing cellular networks to go dark. Unable to reach his wife again, Darden did the only thing he could do: He went back to his desk at the National Weather Service office in Huntsville, where he had just assumed the role of meteorologist in charge. As damage reports started to roll in from his neighborhood, Darden issued warning follow-ups, coordinated with emergency managers, and tried not to worry too much about his wife and daughter. It wasn't easy. "When the phone goes dead and you start hearing reports of damage from your neighborhood, immediately the worst goes through your mind," said Darden, now the meteorologist in charge at the Birmingham Weather Service office. "You can't divest yourself from the reality of what's going on around you."

"Travel to Florida is surging this summer, but so are storm-related delays"

"Travelers are flocking to the Sunshine State just when the weather is most turbulent and unpredictable. In April 2020, at the height of the coronavirus pandemic, the number of daily flights overseen by the Federal Aviation Administration dipped below 11,000. Now, with coronavirus vaccination rates trending upward and case numbers relatively low, Americans are ready to travel again. The FAA is managing 40,000 flights a day at this point and expects to handle as many as 48,000 flights daily by the end of the summer. "We're already seeing traffic is back," said Daniel Murphy, director of National Airspace System Operations at the FAA. "If you have money, you want to go on vacation. You're going to places in the United States like Florida." For the past year, meager air traffic has meant minimal delays, even in the face of inclement weather. With so few flights, planes waylaid by storms weren't likely to end up in a holding pattern at their destination waiting for an open runway. The recent surge in air traffic, however, has led to more delays, particularly in Florida. Meteorologist photographs stunning cloudburst over Florida from plane Murphy said the number of flights to Florida is actually 10 percent higher than it was at this time in 2019, before the pandemic, posing an unusual challenge for air traffic controllers."

"A Structure In Deep Space Is So Giant It's Challenging Standard Physics"

"Scientists have discovered a structure in the distant universe so immense that it is actually challenging our understanding of the universe. Known as the Giant Arc, this crescent-shaped stream of galaxies stretches across 3.3 billion light years, making it about one-fifteenth the radius of the entire observable universe. The unusual discovery was recently announced by Alexia Lopez, a PhD student at the University of Central Lancashire who detected the Giant Arc, at the 238th virtual meeting of the American Astronomical Society. "It's so big that it's hard to explain with our current theories," Lopez said during her presentation on June 7. Lopez first spotted the structure, which is located 9.2 billion light years from Earth in the constellation Bootes, in observations captured by the Sloan Digital Sky Survey, based in New Mexico. At the time, she was researching a technique called the magnesium II (MgII) method that probes the spectral fingerprints of ionized magnesium in space to detect structures that might otherwise remain hidden. "The Giant Arc was a serendipitous discovery," Lopez said in an email. "I was working on understanding the MgII method and how well it worked, when this one particular piece of sky I was testing happened to show the first hints towards something exciting. That's when I started to look more into this bit of sky and slowly, but surely, the Giant Arc was revealed."
