Cool sweep to erase heat, high humidity in Northeast
The Northeast will get some breaks from heat and humidity over the next week to 10 days as periodic waves of air from Canada sweep in. A more prolonged cool break is likely by this weekend.
Even hurricanes far out at sea can trigger dangerous rip currents along the coast. AccuWeather’s Ariella Scalese shares essential tips for staying safe when surf conditions turn rough.
A quick dose of cooler, less humid air rolled across a large part of the Northeast on Monday and shaved temperatures by 15-20 degrees Fahrenheit.
Some folks were able to turn off the air conditioner even along the Interstate 95 corridor on Monday night as temperatures dipped into the 30s over the coldest spots of the interior Northeast, while most locations will have lows in the 50s and 60s.
On Tuesday, drier air will continue to push southward along the mid-Atlantic coast. However, the moisture that was barely pushed away farther west will rebound.
The result will be an uptick in cloud cover and at least sporadic shower and thunderstorms from western and central Pennsylvania and western New York back through the Upper Midwest.
Some of the storms that erupt in the Midwest can be severe with strong wind gusts and flash flooding.
As another cool front approaches, there is likely to be a proliferation of shower and thunderstorm activity in the Northeast at midweek.
Another press of slightly cooler and drier air may settle into the Northeast later this week.
Meanwhile, as batches of cool and humid air exchange hands in the Northeast this week, Hurricane Erin will move northward just off the Atlantic coast of the United States.
People heading to the beach from Tuesday on should expect building surf and increasing rip currents due to Hurricane Erin at sea. If conditions become too dangerous, officials may prohibit swimming on some beaches. If swimming is allowed, because of the danger, only swim under the watchful eyes of lifeguards.
A few days after Erin departs North America by way of the North Atlantic, a large dip in the jet stream is forecast to develop from the Midwest to the Northeast. This dip will direct much cooler air in front Canada.
Depending on the wind direction, smoke from ongoing wildfires in central Canada could once again be directed into the Midwest and Northeast.
