U.S. Midwest, Northeast May Cool Next Week as Heat Breaks

July 03, 2012

The U.S. Northeast and Great Lakes region, including Chicago, may return to more seasonal temperatures starting next week while heat takes hold in the Pacific Northwest.

Temperatures in the coastal Northwest are expected to rise at least 5 to 7 degrees Fahrenheit (2.8 to 3.9 Celsius) above normal from July 8 to July 12 while the East cools from the current heat wave, according to MDA EarthSat Weather.

“This shift will bring a notable warming trend to the Northwest, an area that has struggled to warm on a consistent basis over the past several months,” said MDA, based in Gaithersburg, Maryland.

Temperatures may drop to the low 80s in New York and upper 80s in Washington next week, according to AccuWeather Inc. in State College, Pennsylvania.

Cooler weather in the large cities along the East Coast may curb demand for electricity for air conditioning, pushing down prices on spot and futures markets. Power plants account for 36 percent of U.S. natural gas demand.

Heat will bear down on the central U.S. from Missouri to the mid-Atlantic states until the weekend, said Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland.

“We should see lots more 100-degree readings, especially in the southern Midwest, Plains and interior Deep South,” Rogers said. “But cities like Chicago and into the mid-Atlantic should also pick up a few more century readings.”

Records Set

Through yesterday, 295 daily high temperature records were tied or broken across the U.S. so far this month, according to the National Climatic Data Center in Asheville, North Carolina.

High temperatures in Chicago may reach 101 and rise above 100 every day until week’s end. St. Louis is also expected to have highs above 100 through the rest of the week.

In Washington, temperatures are forecast to be in the 90s for the rest of the week, peaking at 99 this weekend, according to the National Weather Service. New York may reach 90 today and have highs in the 90s for the remainder of the week.

Temperatures may reach 91 in Toronto and 86 in Montreal, according to Environment Canada.

New York, Chicago, Washington, Richmond, Atlanta and Boston all have a chance of thunderstorms for the night of the July Fourth holiday.

For July 10, the normal average temperature in New York City is 77, according to MDA. It’s 73 in Boston; 80 in Washington; 80 in Atlanta; 75 in Chicago; 84 in Houston; 65 in Seattle and 74 in Burbank, California.
