"Pacific Northwest faces one of its most severe heat waves in history"
"Record high temperatures are forecast to be broken in Portland and Spokane, and approached in Seattle. Forecasts for a heat wave of historic proportions in the Pacific Northwest have solidified, and a consensus is building among meteorologists that this could rank among the most extreme events the region has ever seen. National Weather Service forecast offices in Portland, Ore., Seattle and Spokane, Wash., have all used the word "unprecedented" to describe the expected heat and are warning about its potentially lethal effects, considering significant portions of the population lack air conditioning. Numerous cities are predicted to approach or surpass their hottest weather ever recorded in June and probably any calendar month. Washington, Oregon and Idaho could challenge state highs, which are close to 120 degrees, according to the National Weather Service. With projected temperatures 15 to 30 degrees above average, the heat wave will be exceptional for its intensity. The duration, with triple digit afternoon highs and unusually warm nights lasting three to seven days, will also be brutal. Excessive heat watches and warnings affect over 13 million people, covering parts of northern California and western Idaho and much of Oregon and Washington, except for areas right along the coast. The excessive heat warning in effect for the area around Portland calls for "dangerously hot" temperatures Saturday through Monday. The temperature in Portland is predicted to reach 109 degrees on Sunday, which would break its all-time record of 107 degrees."

Weekend Heat Wave in the Northwest Unlike Any Other
- A heat wave will impact areas of the Pacific Northwest this weekend.
- There is potential that this heat wave may be historic. Some have a chance, to high chance of breaking all-time record highs. This heat can not be underestimated. It will be potentially life-threatening, especially to sensitive populations.
Excessive Heat Watches/Warnings/Advisories
Heat Advisories, Excessive Heat Watches, and Excessive Heat Warnings cover areas of Washington state, Oregon, California, Nevada, Idaho, Montana, and Canada.
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.
Local Forecasts
Seattle: Excessive Heat Watch from 2:00 PM Friday to 9:00 PM PDT Monday. Dangerously hot conditions with afternoon highs in the 90s and near 100 possible Saturday through Monday.
Spokane: Excessive Heat Watch from 2:00 PM Friday to 7:00 PM PDT Wednesday. Dangerously hot conditions with afternoon highs near and over 100 degrees likely Saturday through Wednesday.
Portland: Excessive Heat Warning from 10:00 AM Saturday to 11:00 PM PDT Monday. Dangerously hot temperatures of 98 to 103 likely, with temperatures locally 103 to 108 are possible. Overnight low temperatures mostly 65 to 70 degrees
Boise: Excessive Heat Watch from noon Sunday to midnight MDT Thursday. Dangerously hot conditions with temperatures of 100 to 112 possible in the lower valleys and 90 to 100 in the mountain valleys.
Reno: Dangerously hot conditions with temperatures up to 105 possible for northeast California, the Sierra Front and Mineral County, and up to 108 degrees possible for the Western Nevada Basin and Range region including Fallon and Lovelock.

Scorching Heat Wave Shifts to West Coast
By Paul Douglas
I've had plenty of duh-moments in my life, but a recent one in Seattle stands out. My oldest son and daughter in law were living in an apartment and it was hot (upper 80s). I marched down to the main desk and informed a friendly staffer that the A/C wasn't working. She looked at me with a mix of sadness and disgust, saying" This is Seattle. We simply don't need air conditioning. That's what the Pacific Ocean is for."
A stalled high pressure "heat dome" will prevent cooling winds from reaching the Pacific Northwest. Seattle and Portland may see a record-smashing 105F early next week (with no A/C in most homes).
A Canadian breeze keeps us in the 80s into next week with showers and T-storms Saturday PM into Tuesday. No scorching heat is expected here into next week, but some models bring a few 90s back into Minnesota after the 4th of July.
Moderate to severe drought is expanding across Minnesota and many are concerned. No "risk of storms" or "threat of rain". From now on it's an "opportunity for puddles".

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.
National High Temps Friday
The weather outlook on Friday shows cooler unsettled weather across the middle part of the country, where strong to severe storms and locally heavy rainfall will be possible. Some of the most extreme warmth for the end of June will set up in the Northwestern US and will intensify significantly as we head into the weekend and early next week.
National Weather Outlook
The national weather outlook through PM Saturday shows widespread showers and storms ongoing showers and storms across the Central US. Some of the storms could be strong to severe with locally heavy rainfall and flash flooding.
Extended Precipitation Outlook
According to NOAA's Weather Prediction Center the heaviest rainfall through the weekend and into next week will set up from the Texas Panhandle to the Great Lakes. Some of the heaviest tallies could approach 3" to 6" or more from near Kansas City, MO to Chicago, IL.
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."
