San Francisco experiencing coldest summer since 1982, with only two days above 70 degrees
Downtown San Francisco observed rain for four days of the past seven, including Saturday morning.
It's not a lot, but it's better than normal by about sixfold.
The marine layer has been keeping the area way cooler than normal. In fact, it's the city's coldest summer since 1982.
There have been 14 days this year with temperatures above 70 degrees, but only two occurred during the summertime.
Normally, the city would have seen 14 days at or above 70 degrees just at this point in the summer, June 1 - July 25. Cooler-than-normal conditions will continue through the end of the month and the beginning of August.

Fifth wettest July on record to end with sunny weather
As one of Calgary's rainiest Julys on record draws to a close, Calgarians can look forward to a few days of reprieve from the wet weather, followed by another rainy weekend. This month was the fifth wettest July on record, with 139.6 millimeters as of Sunday evening — more than double the average precipitation for July. 'We could move into fourth place or even third place today, depending on if we get into another thunderstorm,' said Crawford Luke, a meteorologist at Environment and Climate Change Canada. 'There was one earlier this morning, and we could expect another one later today.' The rainiest ever July was in 1927, which saw a total of 245.4 millimeters of precipitation.

Some areas, including Bow Valley, Canada Olympic Park and Cochrane, were the chilliest on record for that day. Beginning Tuesday, however, Calgarians will be able to enjoy a few days of sunny weather — though it may come with higher-than-average humidity after the record-breaking rain. Though more showers are predicted for the upcoming long weekend, current forecasts are showing that the weather should improve in August. 'It looks like, overall, it's going to be average for precipitation over the next few weeks, and temperatures should actually be on the warm side,' Luke said. River flows elevated, but no flooding expected River levels are currently higher than normal for this time of year, but are not yet at risk of flooding, according to Frank Frigo, the city's manager of environmental management. 'Though flows are elevated, they're not at the point where any kind of overland flooding is expected, and no flood response is anticipated,' he said. However, anyone spending time on or around Calgary's rivers in the coming days should be cautious of other risks associated with elevated flows, Frigo said. 'When we have higher flows like this, the temperature of the water is cooler,' he said. 'We have the potential for near-bank erosion, and the turbidity is high — that means you can't really see through the water to notice any potential debris or hazards that might be there.' Debris in the rivers tends to collect around bridges, so extra caution is advised for those areas. Frigo said the city has also responded to more than 560 service calls over the past 10 days due to localized flooding throughout the city. 'We are seeing some localized and shorter-term ponding in open spaces and on roadways, streets and green spaces as well,' he said. 'We're trying to address those in a prioritized manner.' Calgarians are encouraged to call 311 to report any flooding concerns.

Summer nights are getting warmer due to climate change, sparking health concerns
When you typically think about extreme heat, a sweltering, sunny day may come first to mind. But climate scientists are also sounding the alarm on warm summer nights, saying they are quietly becoming a worrisome consequence of climate change -- and a serious public health concern. When nighttime temperatures don't drop low enough relative to peak daytime heat, it is harder for people to cool off, according to Climate Central, a nonprofit organization that analyzes and reports on climate science. Extreme heat is the leading weather-related killer in the United States, with heat waves responsible for more deaths than other extreme weather events like tornadoes, flooding, or hurricanes, according to the National Weather Service. This week, more than 200 million people across the U.S. from South Dakota to Florida and up the East Coast to Boston, are on alert for widespread, dangerous heat. Extreme heat warnings have been issued for large cities from Iowa to Florida, including New Orleans, Memphis, St. Louis, Omaha, Des Moines, Savannah, Raleigh, Charleston and Sioux Falls. In these areas, feels-like temperatures are forecast to soar into the triple digits during the afternoon hours, with the dangers remaining even after the sun sets. A dangerous temperature trend From 1970 to 2024, Climate Central analyzed average summer nighttime temperatures in 241 locations across the U.S. The organization found that these temperatures have warmed in nearly all locations, increasing by 3.1 degrees Fahrenheit on average.

In many regions across the country, the EPA reports nighttime temperatures are projected to remain above 70 degrees Fahrenheit more often. Health risks The most serious health impacts of a heat wave are often associated with warm overnight temperatures, the EPA warns. The Centers for Disease Control and Prevention (CDC) echoes these warnings, saying if the air stays too warm at night, the body faces extra strain trying to regulate body temperature. Without this crucial drop in temperature, vulnerable populations -- including elderly people, children, and those with pre-existing conditions -- face heightened health risks, according to the agency. MORE: Heat stroke vs. heat exhaustion: Safety tips as dangerous temperatures hit US Prolonged exposure to high heat in the evenings has been linked to poorer sleep quality, which can impair immune function, exacerbate mental health issues, and increase the risk of chronic conditions such as heart disease, according to the CDC. While extreme heat and triple-digit temperatures frequently are the focus of attention and grab headlines, the lack of adequate overnight cooling is also a serious concern that amplifies the impacts of heat. Overnight cooling is essential for not just the human body, but infrastructure and ecosystems to recover after a hot day. Cities feel heightened temperatures Warmer overnight temperatures are also fueled by urban development. Cities with heat-retaining concrete and asphalt are particularly vulnerable to higher temperatures when vegetation is lost to more paved surfaces and buildings, according to the EPA. Compared with surrounding rural areas, urban locations have higher overall temperatures, especially at night. This is known as the "urban heat island" effect. Rising concentrations of greenhouse gases and increased atmospheric moisture are major contributors to the ongoing rise in nighttime temperatures seen in recent decades. As the atmosphere warms, it can hold more water vapor, which functions like an insulating layer, trapping heat and significantly limiting the amount of cooling that can occur at night, according to the National Oceanic and Atmospheric Administration (NOAA).

Washington County businesses cleaning up after being hit by flash flooding
Communities across Washington County are cleaning up Monday after being damaged by flash flooding. Several business owners in the southern part of the county say at least three inches of rain fell in just one hour. While some were able to open up, others were left with too much damage. "It was heartbreaking," Knot just hair owner Shannon Terensky said. Floodwaters swept through parts of Washington County Saturday night, turning creeks into rivers, flooding anything in their path, including businesses in this North Franklin Township Plaza. "We saw the gush of water come from behind the building, and there was nothing we could do," Terensky said. Shannon Terensky, owner of Knot Just Hair, walked KDKA-TV through her salon as her cleanup continues. She said the water got as high as the seats on the hydraulic chairs, and she lost most of her product after a shelf fell over into the water. She says it's difficult to see her business like this because it's her livelihood. She hopes she'll reopen by Tuesday. "We just have to scrub every corner, everything, and just make it not smell like a creek in there," Terensky said. Just down the sidewalk, the owner of Scotty's Ice Cream also had a mess to clean up. A time-lapse video they shared with KDKA-TV shows the parking lot going from wet to flooded in just about an hour. "It was like a river going around the building here. It was about 18 inches high on this wall. It was just craziness," Scotty's owner Ronald Ranko said. "I couldn't see the bench of our picnic tables, and our dumpster was all the way down there," Scotty's employee Carissa Coulter said. Ranko says, thankfully, Scotty's was open at the time because they were able to respond quickly once water started flowing inside. Employees were able to get products and anything else that could get exposed to water outside. Scotty's was only closed for one day, and Ranko credits the community for pitching in with the cleanup. "It's just a good community. Small business people stick together around here," Ranko said.
