The U.S. Northeast is expected to cool down by next week after setting a record for heat during yesterday’s Boston Marathon, while the West gets warmer.
Temperatures in the Northeast may be 2 to 6 degrees Fahrenheit (1.1 to 3.3 Celsius) below normal from April 23 to April 27, said David Salmon, owner of Weather Derivatives in Belton, Missouri. Temperatures in the West may reach 10 to 14 degrees above normal, Salmon said in his 6- to 10-day forecast.
“An already warm forecast in the West turned even warmer today,” according to MDA EarthSat Weather in Gaithersburg, Maryland. “Drought conditions across much of the West help to support the stronger spikes of warmth as well.”
The high in Boston for race day was 87, breaking the record for the date of 84 set in 2003, according to the National Weather Service. New York City’s high was 88, below the 2002 mark of 92.
Commodities traders watch temperature predictions to gauge energy use and demand. About 51 percent of U.S. households use gas for heating, according to the Energy Department.
Demand for gas from electricity generators peaks in the summer months to meet air conditioning needs. Power plants consumed about 31 percent of U.S. gas supplies in 2011, department data show.
Heat is expected to remain in the West until next month, according to an 11- to 15-day forecast, covering April 27 to May 1, from Commodity Weather Group LLC President Matt Rogers.
Temperatures across the region may be 2 degrees above normal, while in from Montana to western Nebraska they may be 8 degrees higher, he said from Bethesda, Maryland.
The Midwest, South and East may be more seasonal during the period, Rogers said.
The normal average temperature for April 19 in New York is about 54 degrees Fahrenheit (12 Celsius), according to MDA. It’s 50 in Boston, 51 in Chicago, 59 in St. Louis, 63 in Atlanta, 64 in Dallas, 70 in Houston, 51 in Seattle and 62 in Burbank, California.
