Heavy Rains and Flash Floods Threaten Midwest and Ohio Valley
Severe, slow-moving storms are expected to sweep across Illinois and Indiana on Sunday, with some areas potentially getting up to 11 inches of rainfall, significantly raising the risk of flash flooding, forecasters said. The threat stems from a cold front moving into the region, particularly in the afternoon, and stalling there, creating conditions for repeated rounds of storms that could unload torrential rains. The Weather Prediction Center has issued a Level 3 out of 4 risk for excessive rainfall across central Illinois. The center said rainfall rates could reach three to four inches per hour, and up to eight inches in some areas. Frank Pereira, a meteorologist at the Weather Prediction Center, said that a significant amount of atmospheric moisture was contributing to the risk of intense rainfall. 'Typically during the summer, we get warm humid air masses,' he said. 'But this is on the higher end of that.' A Level 2 out of 4 risk for flash flooding extended from eastern Iowa and northern Missouri to western West Virginia and as far south as northeast Georgia and western North Carolina. Much of this region was under multiple flood watches on Sunday. Damaging winds, hail, tornadoes and other types of severe weather were also a concern. The Storm Prediction Center placed central Illinois, Central Indiana, southern Ohio, northern Kentucky and southeastern West Virginia under a Level 2 out of 5 risk for severe storms on Sunday. The main threats included strong, potentially damaging winds and isolated hail. There was a low risk for tornadoes. The risk of flash flooding was expected to persist into the week. 'Indiana, Kentucky, Tennessee, there's a concern the storms in those areas may be impacted by more additional heavy rains going into Monday,' Mr. Pereira said. 'So if you get back-to-back or repeated storms, that could really elevate flooding concerns.' The Weather Prediction Center has issued a Level 2 out of 4 risk on Monday for excessive rainfall across those states, as well as for southwestern West Virginia and the far west of Virginia. The ground will already be saturated from Sunday's storms, forecasters said, and additional rainfall could reach up to three inches an hour, and locally as much as five inches, causing conditions ripe for flash flooding.

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.
