Tropical Storms Barry And Flossie Forecast To Form In Southern Gulf, Eastern Pacific. Warning Issued In Mexico.
The tropics have quickly come to life on either side of Mexico, and that is forecast to generate two named storms, Barry and Flossie, in the next day or so. - The big picture: A large pocket of moisture is pushing westward through Central America and the eastern Pacific, within which there are two systems that are expected to develop. Direct impacts by a tropical system in the United States are not expected, but some moisture could reach the Southwest late in the week ahead. - Gulf system: Previously known as Invest 91L, this was designated Tropical Depression Two by the National Hurricane Center Saturday afternoon. It is producing thunderstorms over parts of southeastern Mexico and the Bay of Campeche. A tropical storm warning has been issued along parts of eastern Mexico's Gulf Coast from southern Tamaulipas to northern Veracruz states, including Tampico. This means tropical storm conditions are expected in these areas, in this case, Sunday into Sunday night. It is forecast to gain enough strength to become Tropical Storm Barry, the second storm of the 2025 Atlantic hurricane season. But it doesn't have a long runway before it comes ashore in eastern Mexico by late Sunday or early Monday. Locally flooding rainfall is likely the main threat with this system. Parts of eastern Mexico, especially near Tampico, could pick up 3 to 6 inches of rain, with isolated amounts of 10 inches, according to NOAA's Weather Prediction Center. Tropical storm force winds, some elevated surf and rip currents can also be expected along eastern Mexico's Gulf Coast. - Pacific system: Invest 95E is expected to develop into Tropical Storm Flossie in the next day or so as it moves northwestward near or offshore of the Mexican coastline. Most computer models suggest Flossie may top out either as a tropical storm or low-end hurricane. While the forecast is still uncertain, some outer bands of rain may soak areas near Mexico's Pacific coast, leading to flash flooding. Rip currents and high surf will also likely eventually develop. Tropical moisture from this storm could be sucked northward as a burst of monsoonal moisture into the Southwestern US before July 4th. (MORE: What is an Invest?)

For Eastern US, temperatures swing high, then swing low. They'll soon go back up
After days of blistering heat, the nation's sweaty East Coast got to open windows, step outside and get temporary relief on Friday as temperatures plummeted as much as 40 degrees and humidity dropped alongside. At least 68 record highs were set and more than 20 places logged triple-digit heat from Sunday through Wednesday before a cold front from the north broke a heat dome's grip on the region Friday. Boston, which hit a record 102 Fahrenheit (about 39 Celsius) on Tuesday, was at 61 (about 16 Celsius) on Friday. That blast of cool comfort brought temperatures as much as 10 to 15 degrees below normal but didn't come close to breaking cold records, said Frank Pereira, a meteorologist at the National Weather Service's Weather Prediction Center. About the only place that could break a cool record of any kind Friday is one tiny station in Philadelphia, at the Franklin Institute, where the lowest recorded high for the day is 75 (about 24 Celsius). It was expected to get up to only about 72 (about 22 Celsius), Pereira said. But records don't go back very far at that site and meteorologists in Philadelphia don't consider it representative of the area, which is unlikely to get a record for cool, said meteorologist Ray Martin in the local weather forecast office in Mount Holly, New Jersey. That's what's so telling about this weather whiplash from hot to cool — and soon to go back to hot — said Climate Central chief meteorologist Bernadette Woods Placky. 'We've had so many record highs, not only our daytime maximum temperatures, but our overnight low temperatures throughout a widespread region of the country, so this massive shift feels great and it's giving everyone a break, which is nice,' Woods Placky said. 'But it's not necessarily coming with record lows on the other side.' That's a signature of human-caused climate change from the burning of fossil fuels, she said: 'We're getting so many record highs any more that it doesn't feel like it's big news because it's happening so often. But we just don't get as many record lows as frequently.' Climate Central's record tracker shows 68 high temperature marks set since Sunday and only three low ones: Billings, Montana; Casper, Wyoming; and Jackson, Idaho — all recorded on Sunday. For the first five months of this year, there have been nearly twice as many daily high records — 14,863 — set in the United States as low records — 7,855 — according to records compiled by meteorologist Guy Walton, who tracks NWS records. For the 2020s as a whole it's well over double with 221,971 daily high records set and 93,429 daily low records set. Except for the Dust Bowl era — which the ratio of highs to lows still don't come close to doubling — the number of record daily highs and lows were within 20% of each other from the 1920s to the 1980s, but since then the ratio of record heat to record cold has taken off. This Eastern cooling won't last, the weather service's Pereira said. Soon the heat will be back and temperatures in the East will once again be above normal, even for summer. But, he said, 'We're not looking at temperatures that are as oppressive as they were earlier in the week.' Weather whiplash from one extreme to another is often a sign of human-caused climate change because the jet stream — the river of air high above us that moves weather systems along generally from west to east — is weakening, getting wavier and getting stuck more because of global warming, Woods Placky and other scientists said. When that happens, it means more extremes such as a heat wave or a drought or downpours. And then when the stuck jet stream moves on, it sometimes results in opposite extreme weather. ___ Isabella O'Malley contributed from Philadelphia. ___ The Associated Press' climate and environmental coverage receives financial support from multiple private foundations.

One more sizzling hot day for the eastern US before temperatures plunge
A record-smashing heat wave broiled the US East for another day Wednesday, even as thermometers were forecast to soon plunge by as many as 30 degrees in the same areas. The day's heat wasn't expected to be as intense as Tuesday, when at least 50 heat records were matched or broken and 21 places hit triple-digit temperatures. About 127 million Americans remained under National Weather Service heat advisories, down from the previous day. Sizzling temperatures sent utilities scrambling to keep the air conditioning and lights on amid massive demand for power. 'It's still going to be, I think, pretty bad across the East,'' meteorologist Bob Oravec of the Weather Prediction Center said Wednesday morning. 'I think today is probably the last day of widespread record potential. It might not be quite as hot as yesterday by a few degrees. But still, high temperatures are expected in the upper 90s across a good section of the East." The weather service warned of 'extreme heat" for a stretch of the country from North Carolina to New York and west to West Virginia. Highs could approach triple digits from New York to Richmond, Oravec said. Temperatures again broke 100 on Wednesday at New York's John F. Kennedy Airport and in Newark and Baltimore. Temperatures Wednesday morning were 'a little bit warmer than expected' because of northwesterly winds bringing 'warm leftovers from yesterday,' said former NOAA chief scientist Ryan Maue, a private meteorologist. Nantucket, Massachusetts, was above 90 degrees Fahrenheit (32 Celsius) when its forecast high was 82. Weather whiplash The high pressure heat dome that has baked the East was forecast to break. A cold front began moving south from New England, bringing with it clouds and cooler temperatures — not only cooler than 100 degrees Fahrenheit (38 Celsius), but cooler than normal. That air mass drawing on cool ocean waters will send temperatures plummeting by the end of the week in Philadelphia, which hit a record high of 101 degrees Fahrenheit on Tuesday, said Ray Martin, meteorologist at the National Weather Service in Mount Holly, New Jersey. Air temperatures will be in the low 70s Fahrenheit (20s Celsius). 'It's going to feel like a shock to the system, but it's not anything particularly unusual,' said Martin. Boston's forecast high for Friday is 34 degrees lower than what it hit Tuesday. 'It's going to feel like a different season," Oravec said. However, it won't last. After one or two days, slightly hotter than normal temperatures are forecast, but not anywhere near the highs from earlier this week, Oravec said. Weather whiplash from one extreme to another occurs more often as the world warms overall from burning fossil fuels such as coal, oil and natural gas, scientists said. Records smashed Tuesday was likely the peak of the heat, with Baltimore the king of swelter. The city's high of 105 degrees Fahrenheit (40 Celsius) smashed a previous record by four degrees. At night, when the human body needs cooling, temperatures only dropped to 87 Fahrenheit (30 Celsius). Baltimore was hardly alone. A dozen weather stations were 101 degrees or higher, including two New York airports. Boston hit 102, breaking its old record by seven degrees. Augusta, Maine's 100-degrees also broke its old record by seven degrees. Every coastal state from Maine to South Carolina hit 100 degrees somewhere, with Georgia and Florida clocking in at 99 on Tuesday. As temperatures rise 'things become less reliable and more unstable,' said Climate Central Chief Meteorologist Bernadette Woods Placky. The heat meant more demand for power. The nation's largest power grid operator, PJM Interconnection, on Monday recorded its highest demand since 2011, with only a slight drop off Tuesday and Wednesday, spokesman Dan Lockwood said. 'We have an aging grid infrastructure already in United States, so you can see the impacts of that heat on that infrastructure," said Kate Guy, senior research fellow at the Columbia University Center on Global Energy Policy. The aging system is less capable of transmitting power at the voltages needed, she said. 'At the same time, you're seeing a really big spike in demand. This is what they (utilities) are increasingly experiencing because of climate change," Guy said. "Frankly, with each year is increased, historic temperatures and that intense heat arriving earlier than ever, just putting an immense pressure on the electrical grid.' Extreme heat caused the road to buckle in two locations on an interstate highway in northern New Jersey. State transportation officials say the impact on the concrete roadway in Morris County on Tuesday afternoon forced some lane closures as temporary repairs were made. Crews then began work to replace the damaged areas and repave those sections. Some downtown Chicago streets will close Wednesday night to repair pavement that has buckled due to hot temperatures amid an ongoing heat wave in the city. 'Pavement failures or blowouts occur when prolonged high temperatures cause the road to expand and buckle up or blow out, resulting in uneven driving surfaces,' the Illinois Department of Transportation said in a statement. In Chesapeake, Virginia, a heat-related malfunction prompted a bridge to remain stuck in the open position.
