Wet start to the week, but pattern changes on the way – AccuWeather.com/ar/

Although the start of the week could start out with a fairly wet system in some Northeast and New England locations, forecasters say a dry and cooler pattern is on the way for some inland areas later this week.

The frequent heavy showers and pockets of strong thunderstorms that developed and tracked the northeastern United States late last week and this weekend will continue into the new week.

“What remains of the suspended boundary that has been at a standstill over much of the region will persist through at least Monday. This means showers and thunderstorms will develop again on Monday as a weak area attempts to break out,” AccuWeather Senior Meteorologist Matt Benz explained. Low pressure that develops off Long Island and southern New England.

Wet and windy pattern to start the week

High dew points will persist across much of the Northeast Monday into Tuesday, especially along coastal areas and beaches, creating “sticky” conditions. Less humid air will begin to creep into the Ohio Valley before the storm tracks over the Great Lakes region on Monday, but that will be quickly disrupted on Tuesday as the cold front associated with this storm brings rounds of rain and thunderstorms to the region.

“There may not be much relief from wet weather as a low pressure area advances eastward from the Great Lakes Monday into Tuesday. Showers and thunderstorms will break out again with this feature across the region on Tuesday with heavy rain possible into the day,” Benz said. Wednesday, especially across parts of New England.

A band of storms could extend from parts of the Ohio Valley, mid-Atlantic states and New England on Tuesday before advancing to the coast on Wednesday. Some of the storms that develop in this area from the beginning of the week through mid-week will be able to make an impact in terms of rainfall totals.

“Atmospheric moisture content will remain very high, especially at this time of year, across much of the Northeast with humidity levels closer to July levels. This means that any thunderstorm will be an effective rainfall producer that could lead to flooding anywhere that sees Heavy rain for a long period.

Rain can fall anywhere from 1-2 inches from the mid-Atlantic states to New England during the first half of the week, with higher totals likely locally in the strongest storms. AccuWeather meteorologists warn that, with the right weather conditions, this pattern can lead to locally severe thunderstorms.

Late last week and over the weekend, a weather pattern led to numerous travel delays across the Northeast, especially for the main hub of New York City airports. The storms have led to widespread grounding and flight delays and cancellations, which could continue in the coming days. Additional storms tracking the area through the beginning of the week could result in additional delays or cancellations, and it is recommended that travelers in the area stay informed of any potential travel plan changes through at least mid-week.

Relief is on the horizon

Although many locations along the Northeast coast will continue to see storms on Wednesday, areas from the Great Lakes extending into the inland Northeast will begin to see a pattern of cool, dry weather. A broad area of ​​high pressure will gradually move southward from Canada and play a big role in the weather that will come late in the week and into the weekend.

Residents across the Mid-Atlantic states through New England can see a decline in humidity levels by the second half of the week, falling from dew points of 60-65 degrees Fahrenheit to nearly half that.

Temperatures are expected to be between 5-10 degrees Fahrenheit lower in most areas by mid-week than early in the week, and this cooling trend will bring values ​​below the historical average for mid-September in places like Columbus, Ohio, Pittsburgh, and Syracuse, New Jersey. York.

For many, this change in pattern that brings clear skies, dry conditions and lower temperatures will feel like fall weather has already arrived. Especially after a remarkably warm start to the month, late-week conditions will give residents the opportunity to break out their fall shirts and perhaps visit a pumpkin patch.

“A cold front will finally deliver a more seasonable air mass into most of the eastern U.S. on Thursday, and this front may play a role in where Lee ends up later this week and into the end of next week,” Benz explained.

By Friday, the weather across much of the Inland Northeast will be fine for those attending outdoor activities such as evening high school football games or picnics. Closer to the coast. However, it will be a different story as Hurricane Lee moves north parallel to the East Coast.

How could Lee affect New England?

This cold front may help steer the tropical system away from the U.S. East Coast, but it’s all about timing, Benz added. If the front can catch Lee, much of the United States may be spared the immediate impacts of the storm, but if Lee misses the front, it could swing west.

Rough seas and strong currents could spread along the East Coast as Lee heads north toward eastern New England and Atlantic Canada by the end of the week and weekend. Based on Hurricane Lee’s current track, gusty winds are expected to spread from coastal Massachusetts northward into areas of Newfoundland and Labrador by the end of next week.

Rainfall totals could range from 1-2 inches across a large area of ​​Nova Scotia, eastern New Brunswick and southwestern Newfoundland, while 2-4 inches of rain are possible in central and southwestern Nova Scotia due to Hurricane Lee.
