April 30 (Bloomberg) -- New York City is forecast to break a 9-year-old record high temperature tomorrow as a blast of unseasonably warm air arrives to start the new month, according to the National Weather Service.
The temperature in New York’s Central Park is expected to reach 89 Fahrenheit (31.6 Celsius), which would break the 2001 record for the day of 87, said John Murray, a weather service meteorologist in Upton, New York.
“Warmer air is getting in at all levels of the atmosphere,” Murray said by telephone today. “It will be especially warm in the city and north and west of the city.”
High temperatures in New York are normally about 66 degrees at this time of year, Murray said. The warm weather throughout the New York and New Jersey area prompted the agency to issue red flag warnings earlier this week, meaning there is an elevated risk for brush fires.
A similar warning has now been issued for eastern Massachusetts and southern Maine and New Hampshire.
Murray said the hot weather will continue through the weekend. By early next week, temperatures will still be above normal, although not as high, he said.
Cooling Degrees
The cooling degree days value for New York in April was 20, 11 higher than the normal value of 9, according to the weather service.
Cooling degree days value is calculated by subtracting the average daily temperature from a base of 65 degrees, and is designed to show energy demand, according to the National Weather Service. The higher the value, the warmer the weather, and thus more energy is probably consumed to cool homes and businesses.
While the U.S. Northeast basks in warmth, states along the Mississippi River will be feeling the brunt of heavy rain.
As much as 8 inches (20 centimeters) of rain is forecast in northeast Mississippi and western Tennessee through the weekend, according to the weather service. Heavy rains are expected to stretch from southern Illinois to northern Louisiana, said Allen Motew, a meteorologist with QT Information Systems Inc. in Chicago.
The rain is expected to boost the height of the Mississippi River, which is already about two feet above flood stage at Cape Girardeau, Missouri. The river is expected to crest at 35.5 feet there tomorrow and then begin falling, according to the weather service.
Flood watches and warnings extend from Illinois and Indiana through Arkansas and Mississippi.
Along the Gulf Coast, where oil from a burned-out rig continues to leak at a rate of about 5,000 barrels a day, high winds are expected to blow the slick into the coastline, according to the weather service. A coastal flood watch extends from the Florida panhandle to Louisiana.
