One more comfortable day expected across Maryland
After a pleasant Tuesday evening with temperatures in the 80s falling into the 70s under clear skies and low humidity, conditions will remain comfortable overnight. Lows will dip into the 60s to near 70, with clear skies and continued dry air.
Wednesday will be sunny with slightly higher humidity, as highs climb into the upper 80s. More moisture will build in Wednesday night, with overnight lows holding near 70 degrees.
By Thursday, summer heat makes a full return. Expect plenty of sunshine, higher humidity, and highs around 90 degrees. The heat intensifies Friday, with afternoon temperatures in the low 90s and heat index values exceeding 100. Friday has been designated a First Alert Weather Day due to the oppressive heat and humidity. An isolated or widely scattered late-day storm is also possible.
Heading into the weekend, a shift in the upper-level weather pattern could bring more active conditions. As a ridge of high pressure retreats westward, the Mid-Atlantic will find itself under a northwest flow aloft. This setup allows upper-level disturbances to interact with hot and humid surface conditions, triggering showers and thunderstorms each day.
Saturday and Sunday could both warrant Alert Day status, with the potential for strong storms and torrential downpours capable of producing flash flooding. Highs will remain near 90 both days, with overnight lows in the mid to upper 70s.
Conditions are expected to dry out somewhat by Monday, offering a brief reprieve before another cold front brings renewed chances for storms by the middle of next week.

Minnesota hiker vanishes in Wyoming's Bighorn Mountains, leaving wife 'trying to stay strong' for their kids
A Minnesota hiker has now been missing for more than a week after disappearing in Wyoming's Bighorn Mountains, with his wife saying that she is "trying to stay strong for the kids." Grant Gardner made contact with his wife on July 29 "letting her know he'd made it to the summit" of the 13,000-foot Cloud Peak, but has not been heard from since, according to the Big Horn County Sheriff's Office. The agency launched a search and rescue operation in what it described as "extreme and very challenging" conditions. "He solo hikes, and he's been hiking for over a decade," his wife Lauren Gardner told Cowboy State Daily. "He's used to this stuff, and he's very detail oriented." "It's all definitely surreal," she reportedly added. "And I'm in shock, I think, and trying to stay strong for the kids. This has never happened in all the years he's gone out. He knows what he's doing and has the skills. I'm just hoping right now." The missing 38-year-old is a father of two children, ages 13 and 11, the outlet reported. The Big Horn County Sheriff's Office said Gardner had planned an approximate 3-day hike "through the Misty Moon Lake area, eventually summiting Cloud Peak, and returning to his vehicle completing his journey." Phone records show he reached the summit of Cloud Peak around 7 p.m. on July 29 and sent a text to his wife indicating that "the climb was more taxing than he expected and he was tired," according to authorities. "The late summit of 7:00pm at 13,000 feet was and is concerning due to the lack of visible trails through cliffs, timber line, boulder fields, and other hazards that had to be navigated after dark before reaching clear trails and safe terrain," Big Horn County Sheriff Ken Blackburn said. Police said Gardner's vehicle later was found by searchers in the same parking lot where he began his trip. "The search is rapidly evolving and ongoing in the Cloud Peak Wilderness area. In addition to high altitude and terrain challenges, difficult weather patterns including winds, thunder and lightning storms have made search efforts difficult at various times of the day," the Sheriff's Office said in a search update this week. "Search and rescue teams from South Big Horn County, Sheridan County, Johnson County, Washakie County, and Park County Wyoming along with other rotor aircraft from First Flight of Wyoming, Wyoming Army National Guard, and private aircraft" are assisting in the effort, they also said. "The Big Horn County Sheriff's Office is requesting anyone who may have had contact with Gardner, please report to the Big Horn County Sheriff's Office at 307-568-2324 or the Wyoming Missing Person Tip line on the Wyoming DCI website," police said.

Over 9,000 San Fernando Valley customers face water outage as LADWP crews repair infrastructure
Vehicles began lining up at free bottled water distribution sites in the San Fernando Valley on Wednesday morning after the water supply was essentially cut off as Los Angeles Department of Water and Power crews were conducting emergency infrastructure repair work. Over 9,000 LADWP customers in the Granada Hills and Porter Ranch area are "experiencing water disruptions," according to the agency. The LADWP said emergency repair work was being done Tuesday afternoon at a pump station that connects to a 10-million-gallon water tank that serves the area when "a valve that controls the flow of water from the pump station to a tank serving the area failed to open." As a result, water flowing into Granada Hills and Porter Ranch was cut off. Meanwhile, repair work and water restoration efforts are underway. Crews connected a mobile high-powered water pump to the system in the Porter Ranch area to resupply water to the tank. Repair work to the valve 20 feet underground will happen once crews finish digging to reach it. LADWP said that repairs are estimated to be complete on Friday. The following drinking water distribution sites are open from 10 a.m. to 7 p.m. on Wednesday:

Torrential rainfall that hit Chicago on July 25 only happens once every 1,000 years
The torrential rainfall that pounded parts of Chicago on July 25 was so extreme, it typically occurs only once every 1,000 years, according to the National Weather Service. Midday July 25, a corridor of extreme rainfall developed along a stalled atmospheric boundary on the south side of Chicago. As much as 5.61 inches of rain fell in Garfield Ridge in just two hours. Extreme rain was also observed in Bedford Park near the border with Clearing, where an unofficial gauge measured 5.98 inches in three hours. Such extreme rainfall rates only have a 0.1% chance of occurring in a given year, according to the NWS. This would have once been referred to as a 1-in-1,000 year rainfall event, but the NWS now avoids that phrasing since there is no guarantee it will be another 1,000 years before it happens again. Other communities from far eastern DuPage County eastward through central Cook County recorded 3 to 5 inches of rain in three hours, including Darien, Burr Ridge, Bridgeview, West Lawn and West Englewood. Rainfall of this magnitude is only statistically expected in these areas once every 100 years. This extremely rare rain event comes on the heels of the July 8 storm that dumped 5 inches of rain in less than three hours on a different part of central Chicago -- an event only expected once every 500 years, according to the NWS. "As of July 25, 2025, the 2020s decade has had five extreme rainfall events in central Cook County," National Weather Service Senior Service Staff Hydrologist Scott Lincoln said. This is a marked increase compared to two extreme rainfall events in both the 2010s and 2000s, and one extreme rainfall event in each the 1990s, 1980s, 1970s and 1960s. As global climate change warms Chicago area temperatures, it is leading to heavier rainfall events. For every one degree of warming, the atmosphere holds 4% more moisture. "Multiple lines of evidence suggest that the threshold for 'extreme rainfall' in the Chicago area is changing," Lincoln said. "Analysis of daily rainfall in Chicago indicated that 'extreme' 1-day rainfall early in Chicago's history (1871-1930) was approximately 6 inches, while this value increased to just over 8 inches in more recent times (1961-2020)."
