Noting that the United States is in for a “long, hot summer,” AccuWeather.com Chief Long-Range Forecaster Joe Bastardi said that air conditioners will definitely be “getting a workout” in most regions of the country. The summer update released Friday was similar to the forecaster’s mid-May outlook (see NGI, May 21).
Bastardi and his team said they expect this summer to be hotter than normal across a large part of the nation, including the most heavily populated areas of the Northeast. On the precipitation front, a majority of the nation will experience close to average levels of precipitation from June through August, but the Southwest and Rockies will see below-normal rainfall, continuing the threat of wildfires in the region. The Southeast, already contending with raging wildfires, will likely see little relief until tropical storms and hurricanes bring moisture as the season progresses.
If a hotter-than-normal summer is realized, the increased air conditioning load could put natural gas and power prices under a considerable amount of upward pressure. “Whenever you start talking about a hotter-than-average summer in the Northeast, especially the middle and late summer, you have to consider the hit that consumers will take to their wallets and pocketbooks as they are forced to cool their homes and businesses longer and more often,” said Ken Reeves, AccuWeather.com director of forecast operations. He added that effects on consumers would be muted should energy prices fall.
The team found that during the second half of the summer most of the Northeast, the Great Lakes region and the Midwest will experience the warmest temperatures relative to normal. Texas will be one of the few exceptions to a hotter-than-normal summer.
Bastardi and his team are basing the AccuWeather.com summer forecast in part on parallels they see to conditions that existed in the 1930s, 40s and 50s. “During that time, torrid heat waves were common across the United States, and hurricanes attacked our coasts more frequently,” Bastardi said. “There is a very impressive resume of nasty weather events that occur whenever we see a transition from warmer-than-normal waters in the tropical Pacific to near-normal or even cooler ocean temperatures, such as we’re seeing now. The overwhelming majority of these events are hurricanes or extreme heat and, in about half of the years, both cause major disruptions.”
Despite the urge to pin the excessive heat on global warming, Bastardi said the facts don’t add up. “The weather events that occur in individual seasons don’t provide conclusive proof of global warming,” he said. “Also, conditions this summer will be similar to the summers of the 30s, 40s, and 50s, and no one attributes the severe weather that occurred then to human-induced global warming, particularly since we entered a period of cooler temperatures soon thereafter.”
Turning attention back to the summer’s precipitation forecast, Bastardi detailed that most of the nation will experience near-normal rainfall, other than the wildfire-prone Southwest and the Rockies. The Great Lakes area, Texas and peninsular Florida are projected to receive above-normal levels of precipitation.
“While the Southeast will experience close-to-average rainfall amounts, we don’t expect any significant relief from the ongoing drought until hurricanes and tropical storms bring additional moisture later in the summer,” said Bastardi. “Though, of course, when you’re talking about the possibility of hurricane strikes, that arrival of moisture is a double-edged sword.”
Bastardi also reiterated that the Southeast is the prime target for this year’s hurricanes, as detailed in the AccuWeather.com Atlantic hurricane forecast released on May 8 (see NGI, May 14).
