Dangerous Heat Wave In The Northwest – National Weather Outlook For Sunday, June 27, 2021

National Weather Forecast

More heavy rain will fall Sunday across portions of the central United States, though some of the heaviest rain across this area is expected to fall Saturday. Storms will also be possible in the Southeast and across New England. The other big story is the heat baking the Northwest through the weekend into the early week timeframe, with all-time record highs possible.

From Saturday through Monday, at least 3-5” of rain could fall from portions of Texas northeastward into southern Michigan. This could lead to flash flooding.

Here’s a day-by-day breakdown of the record heat across the Northwest over the next several days. Many people in the Pacific Northwest do not have air conditioning, so this heat will be even more taxing with the length and severity of the heat. All-time record highs and June record highs could be set in several locations.

ALL-TIME RECORD HIGHS:

• Seattle, WA: 103F (July 29, 2009)
• Portland, OR: 107F (set three times, most recently August 10, 1981)
• Spokane, WA: 108F (set two times, most recently August 4, 1961)
• Medford, OR: 115F (July 20, 1946)
• Redding, CA: 118F (set three times, most recently July 20, 1988)
• Boise, ID: 111F (set two times, most recently July 19, 1960)
• Missoula, MT: 107F (July 6, 2007)

JUNE RECORD HIGHS:

Florida’s Oceanfront Cities Are Not Prepared for Sea Level Rise

More from Gizmodo: “On Thursday, a 12-story beachside condo building just north of Miami Beach collapsed, killing at least four people with almost 160 still missing. It could be a scary sign for the future, particularly as sea level rise undermines the very foundation that South Florida sits on. Long before the Champlain Towers South condominium in Surfside crashed, the building started sinking. An April 2020 study found that the area showed signs of land subsidence—sinking brought on by natural occurrences like sinkholes and exacerbated by human activities like extracting fossil fuels and groundwater. The study’s authors told USA Today that back in the 1990s, the building was descending at a rate of 0.08 inches (2 millimeters) per year, though it’s not clear that that necessarily contributed to its horrific collapse. Officials are just beginning their investigation into what caused the building’s devastating crash. It will take more data to suss out what happened and the role, if any, subsidence played.”

A $26 Billion Plan to Save the Houston Area From Rising Seas

More from WIRED: “When Hurricane Ike made landfall in 2008, Bill Merrell took shelter on the second floor of a historic brick building in downtown Galveston, Texas, along with his wife, their daughter, their grandson, and two Chihuahuas. Sustained winds of 110 mph lashed the building. Seawater flooded the ground floor to a depth of over 8 feet. Once, in the night, Merrell caught glimpses of a near-full moon and realized they had entered the hurricane’s eye. Years earlier, Merrell, a physical oceanographer at Texas A&M University at Galveston, had toured the gigantic Eastern Scheldt storm surge barrier, a nearly 6-mile-long bulwark that prevents North Sea storms from flooding the southern Dutch coast. As Ike roared outside, Merrell kept thinking about the barrier. “The next morning, I started sketching what I thought would look reasonable here,” he said, “and it turned out to be pretty close to what the Dutch would have done.””

Yellowstone and Warming: An Iconic Park Faces Startling Changes

More from Yale Environment 360: “In 1872, when Yellowstone was designated as the first national park in the United States, Congress decreed that it be “reserved and withdrawn from settlement, occupancy, and sale and … set apart as a public park or pleasuring ground for the benefit and enjoyment of the people.” Yet today, Yellowstone — which stretches 3,472 square miles across Montana, Wyoming and Idaho — is facing a threat that no national park designation can protect against: rising temperatures. Since 1950, the iconic park has experienced a host of changes caused by human-driven global warming, including decreased snowpack, shorter winters and longer summers, and a growing risk of wildfires. These changes, as well as projected changes as the planet continues to warm this century, are laid out in a just-released climate assessment that was years in the making. The report examines the impacts of climate change not only in the park, but also in the Greater Yellowstone Ecosystem — an area 10 times the size of the park itself.”
