Cooler Temperatures and More Rain in Store for the Northeast

Posted: September 8, 2023 9:00 am

The Northeast is set to see a dramatic cooldown after a late summer heat wave. However, the falling temperatures will likely come with falling rain across most of the region. Here is what you can expect for the end of the week for this corner of the country.

Storm System Approaches Northeast with Rain and Cooler Temperatures

The arrival of rain and thunderstorms will usher in the start of a cooler weather pattern to a part of the U.S. that has seen exceptionally high temperatures when compared to early September historical averages. This threat of severe weather in the Northeast will hang on into the weekend, potentially ruining some outdoor plans in the region.

A storm system is moving into parts of the East Coast, bringing in an influx of moisture and cooler temperature readings. The humidity levels are also expected to increase as the weather maker approaches the East Coast. In fact, forecasters are warning that the humidity levels could increase incrementally as the temperature decreases. This will translate to some muggy days.

The storms will first fire up late Thursday and early Friday for the major metropolitan areas of Washington, D.C., New York City, and Philadelphia. Daytime highs on Friday will remain in the 90s for most areas up and down the busy Interstate 95 corridor before the cooler temperatures arrive in time for the weekend. Combined with the rising humidity levels, real feel temperatures could break the 100-degree barrier.

The storm cells will bring a number of impacts, including high winds and heavy rain. Northern Virginia, New York City, Philadelphia, and upstate New York will all be under the threat of these risks starting late Thursday.

While this storm system had been moving at a fast clip over the last few days, it is supposed to slow its speed by Friday. This slowdown will support the development of thunderstorms over a specific area for a lengthy period of time. As a result, some areas may see the risk of flash flooding because of the repeated downpours.

More Severe Weather in the Forecast for Friday

The threat of severe weather will become more widespread on Friday. High winds could trigger some power outages during the afternoon and evening hours. The evening commute on Friday could become dicey for areas between New York City and Philadelphia. Torrential rain could also create ponding on roadways and reduced visibility throughout this heavily traveled corridor. Flash flooding may also become an issue.

Although the severe weather risk will lessen heading into the weekend, the chance of rain will linger for a few days. You will want to keep an eye on your local hourly forecast if you have outdoor plans this weekend.

Saturday will likely be the best day of the week if you are in southern New England. The chance of rain will increase late Saturday into Sunday in areas such as Nantucket and Martha’s Vineyard. In addition to the threat of significant rain, frequent lightning strikes could also prove to be dangerous in this part of New England.

Hurricane Lee Impacts

All eyes are on the Atlantic Ocean as Hurricane Lee continues to strengthen as it inches closer to the northeastern Caribbean. Forecasters with the National Hurricane Center (NHC) are predicting that this storm could reach the status of a Category 5 hurricane.

It is too early to discern if the storm will impact the East Coast in the coming days. However, experts are cautioning that rough surf conditions could begin to impact the Atlantic coastline by the beginning of next week. Be sure to stay tuned to the progress of this storm if you live along the East Coast.
