Thunderstorms, tornado risk follow record-breaking heat wave
The heat wave that broke daily record high temperatures across the eastern half of the United States has given way to storms and showers, with a chance for some severe thunderstorms and dangerous winds in the upper Midwest and parts of the Northeast and Mid-Atlantic over the weekend, forecasters said. The storms will feed on the lingering hot and humid air in the central and eastern parts of the country after a dayslong heat wave that saw temperatures in the upper 90s and triple digits in many major cities, AccuWeather reported. On June 28, "all severe hazards" are possible across southern Minnesota and eastern South Dakota as scattered severe thunderstorms settle over the region, the Storm Prediction Center said. Later in the afternoon and evening, storms are expected to develop in parts of Pennsylvania and New York. Wind gusts of 50 to 60 mph are possible, according to the center. Just over 9 million people in these regions are at risk for storm impacts, with major cities including Minneapolis and St. Paul, Minnesota; Sioux Falls, South Dakota; and Albany, New York, in the path of possible severe thunderstorms. On June 27, storms generated preliminary reports of tornadoes, hail and strong winds that downed trees in North Dakota. Some preliminary reports said hail was golf ball- to tennis ball-sized. On June 28, severe storms are expected over the upper Mississippi Valley and the Northern and Central Plains. The storms are expected to bring frequent lightning, severe wind gusts, hail and even a few tornadoes. The hail that falls over Minnesota could be 2 inches or more in diameter, the National Weather Service said. New York's Hudson Valley could be a likely spot for brief tornadoes to form on June 28, AccuWeather reported. By June 29, showers and thunderstorms are expected to form in parts of the Ohio Valley and the Mid-Atlantic, according to the National Weather Service. In some parts of the Mid-Atlantic region, the storms could be strong or severe. Also later in the weekend, frequent lightning, wind gusts and a small threat or tornadoes and hail will move to the upper Great Lakes and upper and mid-Mississippi Valley, the weather service said. More than 2,800 temperature records were broken as much of the eastern half of the country endured the heat wave over the last week, AccuWeather reported. The records included 955 daily high temperature records and 1,899 high minimum temperatures. The heat on June 24 was especially potent, reaching temperatures not felt for over a decade for many East Coast residents. That day, Newark, New Jersey, reached 103 degrees, breaking the 1966 daily high record of 97. Queens, New York, hit 102 degrees, beating the 2010 record of 97 for that date. Philadelphia got to 101 degrees, breaking the 1923 record of 99 degrees for June 24. In many places, temperatures felt even hotter due to humidity. At least one person died amid the heat wave. A woman in St. Ann, Missouri, died in her home due to the dangerous heat after having no water or air conditioning for at least three days, KDSK-TV reported.

Heat returns to Philadelphia Saturday with summertime humidity; gusty evening storms are likely
Saturday turns up the heat in a big way, with highs in the upper 80s and summer humidity making a comeback. It's definitely going to feel like a classic beach day, at least for a while. The catch? We're under a marginal risk (Level 1/5) from the Storm Prediction Center, which means there's potential for strong to severe thunderstorms later in the day. The timing looks to be the evening, roughly 6 p.m. to 10 p.m., and storms could bring heavy rain, gusty winds and even some hail. CBS Philadelphia So if you're making plans – whether it's backyard barbecues or boardwalk rides in Wildwood or Ocean City – aim to do them earlier in the day and be ready to pivot indoors if those storms develop. Sunday stays hot, with highs near 90, but it won't feel quite as muggy. Whether you're staying in the city or relaxing down the shore, it's shaping up to be a solid day to soak up the sun. The breeze off the water will help a bit at the beach, and overall, it looks like a quieter day weather-wise before the low 90s and storms return on Monday. Fourth of July Forecast Next week will be fairly similar day to day with heat, humidity and pop-up storms from time to time. Looking ahead to Friday, your July 4th plans should be rain-free if models hold. Our NEXT Weather team will keep you posted. Here's your 7-day forecast: CBS News Philadelphia Saturday: P.M. thunderstorm. High 89, Low 68. Sunday: Partly sunny. High 90, Low 73. Monday: Back to the 90s. High 91, Low 72. Tuesday: Thunderstorms are likely. High 88, Low 76. Wednesday: Mostly sunny. High 89, Low 72. Thursday: Mostly sunny. High 89, Low 71. Friday: Mostly sunny. High 89, Low 69.

Tennessee communities could see 'ring of fire' storms as heat dome continues to broil part of U.S.
From the Midwest to the East Coast, Americans are feeling the heat, but some will soon see a round of thunderstorms known as the "ring of fire." The Southeast and the mid-Mississippi Valley can expect a "ring of fire" cell of thunderstorms at the leading edge of a massive heat dome that has enveloped a portion of the nation over the last few days, according to the Storm Prediction Center. Some communities in Tennessee are right on the edge of the heat dome, and could potentially see severe thunderstorms with damaging winds, but others will just continue to see the oppressive heat. Here's a look at where in Tennessee should expect the "ring of fire" storms and just how long this heat wave could last. It's not the Johnny Cash song you may be thinking of, but this "ring of fire" is a weather phenomenon that occurs when a heat dome forms and thunderstorms form along the edge of it. The "ring of fire" occurs when thunderstorms and rain form along the border of a ridge of high pressure, according to the National Weather Service. That ridge allows for a heat dome to form, and while the weather (although unbearably hot) stays relatively stable inside the dome, on the edge, thunderstorms can pop up in clusters. There, the air is cooler up in the atmosphere, allowing storm-producing clouds to form, according to AccuWeather. According to the National Weather Service, East Tennessee has the highest likelihood of seeing storms related to the ring of fire. The Storm Prediction Center's latest forecast shows thunderstorms packing dangerous wind gusts expected across parts of North and South Carolina and the Southeast starting on June 25. Knoxville and communities in East Tennessee along the North Carolina border are predicted to start seeing storms form after 2 p.m. ET. Storms are expected to continue through the weekend. While the eastern part of the state could see the brunt of storms, Middle and West Tennessee could see some storms heading into the weekend. A heat dome isn't technically a scientific term and is a fairly new term that has gained popularity in recent years. It is a condition that occurs when a persistent region of high pressure traps heat over a certain area for a period of time, according to the American Meteorological Society. A heat wave is a period of abnormally hot weather generally lasting more than two days, according to the National Weather Service. It's not just humans that need to keep cool during the oppressive heat that has settled. Check out the video below for tips on keeping your furry friends safe and cool during this heat wave. The National Weather Service will issue a heat advisory usually happens when extremely dangerous heat is about to hit and is one of several types of health alerts issued by the federal agency. A heat advisory is issued within 12 hours of the onset of these conditions. Here are the heat advisories issued from the National Weather Service for Tennessee: East Tennessee is under a heat advisory for June 25 until 7 p.m. local time. Middle Tennessee is under a heat advisory through June 27 at 7 p.m. local time. West Tennessee is under a heat advisory through June 27 at 9 p.m. local time. According to data from the National Oceanic and Atmospheric Administration, the two hottest days on record for Tennessee occurred less than two weeks apart in 1930. Perryville, Tennessee, hit a high of 113 degrees on July 29, 1930, and August 9, 1930. The National Weather Service indicates that Tennesseans could start seeing some cooler temperatures starting next week as temperatures begin to drop to the low 90s and high 80s.

Hot weather continues in the Pittsburgh area with some afternoon storms possible
The heat continues today, but the worst of this current heat wave is now behind us. When we hit 93° yesterday for our high, it became just the fourth time since 2000 that we have had a stretch of four days in a row in Pittsburgh with temperatures hitting 92° or above. WEATHER LINKS: Current Conditions | School Closings & Delays | Submit Your Weather Photos Three of the four times have happened over the last year, with the only instance of it happening being in 2002. That's some crazy heat. As the ridge began to break down yesterday, we did see a couple of places seeing downpours. While the Pittsburgh Airport had only a trace amount of rain, on the other side of the county, in Monroeville, radar estimated rain shows them receiving as much as an inch of rain. Rain totals approached an inch and a half along the West Virginia-Pennsylvania state line. Rain totals expected through Friday morning KDKA Weather Center Today should look very similar to yesterday. I may be being too conservative with my highs, similar to yesterday. Yesterday was one of those days, as soon as I left, I was like "why didn't I go higher?" Sometimes you make silly decisions at 4 a.m. Even with that, I was just two degrees off. Under the circumstances, I am good with it. Storm chances today shouldn't be as widespread as yesterday. I am going for maximum coverage of around 40 percent. Any storms that do develop should be fairly intense, with downpours and gusty winds being possible. The Storm Prediction Center has us under a level one out of five severe weather risk for today. We are also listed as having a low flash flood chance for today. When it comes to the forecast, highs today should hit the 90s again. I am being conservative with my forecast, with Pittsburgh only hitting a high of around 90°. High temperatures expected on Thursday KDKA Weather Center I honestly should have our temperature at 91° or 92°. We hit 93° yesterday. 850mb temps have come down to around 19°C. They were closer to 20°C yesterday. I have highs dipping to the upper 80s on Friday. Rain chances will keep temperatures in the mid-80s on Saturday. Saturday rain chances will be up from today and Friday due to a cold front passing through. Interestingly, Sunday will be warmer behind the front. Humidity levels will be lower, though, so it should feel pretty good. I will keep the rain chance very low on Sunday and Monday, with another front bringing a rain and storm chance on Tuesday. Temperatures will be in the comfy range next week with no big rain chances sticking out at this time. July 4th right now is looking dry and pleasant, but there's still plenty of time for something to change. 7-day forecast: June 26, 2025 KDKA Weather Center Stay up to date with the KDKA Mobile App – which you can download here!

Strong storms with heavy rainfall, gusty winds threaten Miami-Dade, Broward
The NEXT Weather Team has issued NEXT Weather Alert for Thursday and Friday due to the potential for storms with heavy rainfall and damaging winds. The first round of rain arrives in the morning with scattered showers and storms, but they will not be severe. A second round arrives around noon and will last through the afternoon. A few of the storms may produce strong to marginally severe wind gusts, lightning and hail, according to NEXT Weather meteorologist Lissette Gonzalez. On Friday, the most active period for storm activity will be in the afternoon, with a few producing strong to marginally severe wind gusts. The storm activity stems from an upper level low centered across the Florida peninsula which allows a much more unsettled pattern, according to NEXT Weather Chief Meteorologist Ivan Cabrera. While the low will remain well north of South Florida, a moist southeast flow will continue to pull in deep moisture. The Storm Prediction Center has placed all of South Florida under a "marginal" (Level 1) risk for strong storms. The concern is that the storms may also contain damaging wind, and the slow-moving rainfall increases the chance for isolated street flooding. Marginal risk for severe weather. NEXT Weather South Florida will remain unsettled Friday through the weekend, and even into early next week, due to another upper-level low will approach the state late in the weekend into early next week which will provide additional support for showers and storms. All of this will result in above normal rain chances each day. Afternoon highs will remain in the upper 80s with feels-like temperatures in the triple digits.
