Heat wave, drought continues gripping Northeastern states

PHILADELPHIA—The heat wave gripping parts of the country including Philadelphia, where tens of thousands are descending upon the city for the Democratic National Convention this week, is not going away anytime soon.

Excessive heat warnings will continue Monday, the first day of the convention, in the Philadelphia area, most of the Midwest and regions out west. It’s because of a dome of high pressure, meteorologists say, that’s affecting most of the United States and contributing to drought conditions in the Northeast and continuing to fuel wildfires in California.

“It’s fair to say that the vast majority of the nation has been experiencing above normal temperatures for the past week,” said David Robinson, New Jersey state climatologist at Rutgers University.

The dome of high pressure traps hot air and is the basis for the “critical high temperatures” the country has been experiencing the past week, Robinson said, even for being the warmest time of the year.

Thunderstorms are common, as they were in parts of New England over the weekend, but don’t help much with drought conditions in the Northeast and out west. Particularly dry weather in areas like Massachusetts and New York have forced farmers to choose which crops they will water and which will just not survive the season.

“The Northeast is a little bit of a mixed bag, but the bottom line is that the conditions have deteriorated over the past several weeks to a couple of months,” said Rich Tinker, a drought specialist at the National Oceanic and Atmospheric Administration.

In southern California, where drought has persisted for years, 18 homes have been destroyed and more than 34 square miles of brush have been blackened in a blaze that sparked Friday. Los Angeles Fire Chief John Tripp said the fire “started consuming houses” ”like a freight train.”

A main difference between the drought in the Northeast and out west is that the Northeast can pull out of those conditions at any time, Robinson said.

“The good news is that there’s always a chance that the pattern can switch in several weeks at any time of the year,” he added.

Temperatures in the Philadelphia area are predicted to reach their highest points Monday as 50,000 Democrats are expected to arrive there for the DNC.

Higher than normal temperatures are still expected in the six to 10 day outlook. Two weeks out, the temperatures are still slated to be high.

Thousands of protesters, many for climate change, on Sunday braved mid-90s temperatures as the city provided free water and “misting tents” to demonstrators, some of whom are walking several miles.
