Autumn quotes fall11/23/2023 That means leaves could change earlier than usual.Īnd the change itself could be lackluster. For one, the summer’s heavy rains could have waterlogged the trees’ roots and interfered with respiration, the process of converting sugars into energy. Salge’s latest report revealed his concerns. Related: What exactly are flash floods, like those hitting New York and Vermont this week? Salge has written a New England foliage forecast for Yankee Magazine for more than 20 years. Jim Salge, a former meteorologist at New Hampshire’s Mount Washington Observatory, suggested that extreme flooding earlier this year in Vermont could lead to disappointment for fall leaves. As a result, Pastelok said, colors in about a dozen states could be dull compared to other regions of the country. “On top of that, we could see a big change in October where some cold air can come down causing an early frost,” Pastelok added. The U.S.’s mid-section, down into Texas, could see much duller fall foliage than in other years after the extreme heat of summer. Severe weather events during the first half of fall could blow leaves off of the stressed trees around the same time as peak season. have put quite a bit of stress on trees from Texas to Alabama and northward into Illinois and Indiana. Long-duration hot spells over the southern U.S. Some colors are expected elsewhere across the Rocky Mountains, the Cascade Mountains and most of the Appalachians, but there is one larger zone where Pastelok said colors may not be quite as vivid. “The aspens should come out looking really good in late September to mid-October,” Pastelok added. This includes popular leaf-peeping destinations such as New England, the Upper Midwest and the aspen groves in Colorado and Utah. “The best places to check out the fall foliage this season is probably going to be across the Northeast, the Great Lakes, and then even the West,” AccuWeather’s Pastelok said. Where’s the best place to see brilliant fall foliage this year? An early frost can lead to brittleness for already thirsty leaves and impact how long those leaves can hang on branches before gravity pulls them to the ground. But if it gets too cold, too fast, leaf-viewing time will be crimped. In the weeks before their transformation, trees prefer warmish, sunny days and crisp, cool nights to bring on the most vibrant color transformation.įor sure, a mild fall that brings some cooling relief will be embraced by much of the country’s trees and its people. Open semifinal eventually won by Coco GauffĮlsewhere, parts of Nevada, Colorado and New Mexico tied their all-time temperature highs this summer, while portions of Arizona marked their highest-ever night-time temperatures. Northeast, too, including in recent days and nights during the U.S. There were a couple of extreme-heat spells in the U.S. That translated to a record string of days above 90 degrees F for Phoenix, and hot and humid conditions above 100 degrees F over an uncomfortable run of days in areas of Texas. Blame global warming and El Niño.įor the globe, August averaged about 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than pre-industrial averages. Read: It’s official: This summer was the hottest on recordĪnd: July 2023 is the hottest month ever recorded. A recent report issued by the U.N.’s World Meteorological Organization declared summer 2023 the hottest on record as persistent global warming from burning fossil fuels like coal and oilĪlong with the shorter-term heat impact from an early showing of an El Niño, drove the thermometer higher from Texas to New York to Spain to China. In fact, the heat this summer for many parts of the country rewrote the record books. 5, government data shows, with 36% of the lower 48 states considered to be in drought, according to the U.S. Nationwide drought conditions rose for the 8th straight week as of Sept. as kids returned to school in recent weeks.ĭrought conditions worsened in the Northwest, Plains, Midwest and from eastern Arizona across to Louisiana and Mississippi. Heat and dryness dominated large parts of the U.S. Late summer conditions aren’t exactly playing fair. On the contrary, drought and intense, long-lasting heat can lead to dull colors, as the conditions put trees under more stress and likely cause them to shed their leaves early, before the normal process of gradually losing chlorophyll has a chance to accelerate before leaves release from tree branches. Wet weather from late spring through the middle of summer is the first step toward securing a brilliant offering of fall foliage, said Paul Pastelok, AccuWeather’s senior meteorologist. How do spring and summer weather impact fall color change? For sure, fall excursions to view the color changes should be pushed ahead to the earliest weeks of autumn in key regions known for their showy fall displays, says AccuWeather.
