How urban planners are working to reduce heat. Thermal imaging shows how hot surfaces get.
With temperatures soaring this week, residents in Cambridge, Massachusetts are doing whatever they can to beat the heat. For many, that means less time outside. "I'm out in this for 10 minutes to walk the dog and then I go home and it's shower time," a Cambridge resident said. Amid the heat wave, public parks with splash pads have been a reprieve for families seeking relief. "I'm here Monday through Friday," said Emily Ortiz, a young woman enjoying the splash pad at Dana Park. As climate change continues to push urban temperatures higher, experts are exploring long-term strategies to make city living more tolerable. Kishore Varanasi is a principal designer at CBT, a firm focused on creating cooler public environments. Using thermal imaging, Varanasi demonstrates just how hot urban surfaces can become. "You can see here the surface is measuring 136 degrees Fahrenheit, but the air temperature is 88 degrees," he said. "So, if I bring it to the shade, you see that it matches the air temperature." Varanasi said that the excessive heat is due to the way cities have been historically designed. "What makes cities hotter is everything that we've built. The air conditioners spitting out heat, the materials that we've used, the asphalt, cars," Varanasi said. "All of it makes cities 10 to 15 degrees hotter." To combat the urban heat island effect, Varanasi and his team are working with urban planners to redesign spaces by introducing more shade and using materials like special concrete mixes that retain less heat. "We also have other alternatives to create shade," he said. For example, you can use structures, like the one at Cambridge Crossing. "It is a part of the park, but it is shaded so on days like this you can be in this space and feel comfortable," he said. It is an effect that can be felt, with temperatures decreasing up to 40 degrees under his shaded structures. As extreme heat becomes more common, Cambridge's push for cooler, shaded spaces may serve as a model for other urban areas grappling with rising temperatures.

There are multiple severe thunderstorm warnings to the west still. The Parker Volunteer Fire/Rescue posted that the new school storm shelter will be open for any families needing shelter from 7 to 11 p.m. Update as of 6:50 p.m.: A tornado was issued for Plankinton, White Lake and Stickney until 7:30 p.m. At least five severe thunderstorm warnings were in effect as of this update, stretching from Gregory to north of Watertown, as the system continues to move east across the state. The storms have yet to reach the Sioux Empire. A tornado warning has also been issued for Wagner, Lake Andes and Marty until 7:45 p.m. Update as of 6:40 p.m.: The NWS says it's closely monitoring two tornadic supercells moving southeast. The one near Pickstown could contain a rain-wrapped tornado. Update as of 6:30 p.m.: Reed Timmer, a well-known meteorologist and storm chaser in the area for today's storm system, captured video of a tornado and wildfire and shared the moment on X. He stated he had seen three tornadoes, wildfire and gorilla hail east of Hamlin and south of Chamberlain so far. Update as of 6:15 p.m.: A tornado warning has been issued for Lake Andes, Bonesteel and Pickstown until 7 p.m. Storm chaser Reed Timmer is in South Dakota tonight, hunting for a tornado One has also been issued for White Lake, Storla and Plankinton until that same time.

Amid the tornado warnings, the NWS has also missed a couple severe thunderstorm warnings, with the latest for Plate, Lake Andes and Burke until 6:30 p.m. the storm has wind gusts of 80 mph, the warning states. Update as of 5:30 p.m.: As storms fire up to the west of Sioux Falls, central South Dakota has already experienced multiple tornado warnings, according to the NWS. Three warnings have been issued so far, with the latest for Bonesteel and Saint Charles until 5:45 p.m., the NWS stated. The tornado was observed, and 2-inch hail was possible at the time. The warning area affects 366 people, and three schools. Before that, a tornado warning was issued for Platte, Bijou Hills and Lucas until 5:30 p.m. The twister was reportedly radar indicated. The area affected by this warning included about 2,300 people, five schools and one hospital. And the first observed for the day with this system was for Lucas and Academy until 5 p.m. That warned area included 550 people and two schools. More to the north, the NWS issues at least two tornado warnings between 5 p.m. and 6:15 p.m. for areas including Stephens and Gann Valley. It's unclear at this time to what extent damage or injuries might exist from any of those warnings at this time. As of 5 p.m., Gov. Larry Rhoden shared on X that his administration was monitoring today's storm system. Earlier story: Chances for severe weather the night of July 28 into the early hours of July 29 have increased significantly in the Sioux Falls area, according to the National Weather Service. NWS' latest update from 12:30 p.m. July 28 about a system expected to bring a "significant wind event" to the area shows the thunderstorm risk level went from enhanced to moderate for the area. The timing was also pushed back to between 5 p.m. and 1 a.m., instead of 4 p.m. and 7 p.m. As of 3:45 p.m., much of central and eastern South Dakota is under a severe thunderstorm watch until 10 p.m., including Sioux Falls, Aberdeen, Brookings, Yankton and Pierre. More: City: Outdoor warning sirens will now sound for 'destructive severe thunderstorm warnings' What's expected for Sioux Falls? While Sioux Falls could see all modes of severe weather tonight, the main concern is the chance of wind gusts reaching 80 mph or greater, or the system evolving into a derecho, with hurricane-force wind speeds. A derecho is a widespread, long-lived wind storm associated with a band of rapidly moving showers or thunderstorms, according to the National Weather Service. A derecho can produce destruction similar to tornadoes, and the term "straight-line wind damage" is sometimes used to describe derecho damage. More: Here's what we know about the tornado confirmed near Watertown on July 27 "By definition, if the wind damage swath extends more than 240 miles and includes wind gusts of at least 58 mph or greater along most of its length, then the event may be classified as a derecho," the weather service says. For Sioux Falls, there's a 45% chance the area may see 80 mph winds or more. What are the other risks for Sioux Falls and surrounding areas? An extreme heat warning remains in effect through 8 p.m. July 28, with heat indices reaching to more than 105 in some areas. There's a 15% chance the area could see hail up to 1.5 inches in diameter, or ping-pong ball sized, which is enough to damage vehicles and homes, according to the NWS. More: 200 million Americans face extreme heat today as a derecho looms And there's a 5% chance of a few tornadoes as well. Localized areas could also see heavy downpours of 1-2 inches of rain, with isolated pockets up to 3 inches possible, the agency stated. More: Derechos are more common in South Dakota than you might think What's next? Sioux Falls has a marginal risk July 29 in the evening for scattered storms to return, but the exact timing and severity of those storms is still to be determined, the agency stated.

Extreme heat returns to most of Massachusetts. See which areas are under heat advisory
Extreme heat is returning to Massachusetts starting Monday and Boston could see its third heat wave of the summer through Wednesday. The WBZ Next Weather Team has issued a Next Weather Alert for high heat on the way for the first half of the upcoming week. A Heat Advisory goes into effect for all of southern New England aside for the Berkshires, Cape Cod, and the Islands starting Monday at 11 a.m. through Wednesday at 8 p.m., with heat index values climbing into the mid 90s to near 100 degrees. Tuesday looks to be the hottest day with actual temperatures climbing into the mid 90s, and feeling more like 100 degrees with the higher humidity. But many towns will also get into the 90s on Monday and Wednesday. If you're looking for some relief from the heat, sea breezes will keep the immediate coast line, Cape Cod and the Islands a little cooler with temperatures in the 80s. Boston could hit 90 degrees or higher all three days, which would make it the third heat wave of the summer for the city. So far this summer, we've already had 14 90-degree days and will likely tack on a few more this week. With temperatures in the 90s and high humidity heat illnesses are possible, it's recommended to drink plenty of water, stay cool in the shade or air conditioned rooms and to try and limit strenuous activities outside. If you don't like the heat there is relief in sight! A cold front mid week looks to bring some showers Thursday followed by cooler, more comfortable air for the end of the week and upcoming weekend!
