Cooler Air from Canada Making its Way Through the Northeast

Residents of the Northeast were certainly soaking up the unseasonably warm weather for the first weekend of November. However, a change is on the way starting Tuesday. Here is what you need to know about this dramatic weather change.

Record Warmth in Northeast Coming to an End

High temperatures soared nearly 20 degrees above average in a large area stretching from the mid-Atlantic, through the central Appalachians, and into New England on Sunday. Runners participating in the New York City marathon were surprised with weather that was more like spring than the end of autumn. While average highs in this part of the Northeast rang in across the 40s and 50s, the temperature climbed into the 70s in many areas by the time the weekend was over.

Although the warmth was welcome by most, the wind was also an issue in the Ohio Valley, the Appalachians, the Great Lakes, and up into New England. Those in the mid-Atlantic saw calmer conditions.

The warmth held on to start the week with major cities such as Boston, New York City, and Washington, D.C. all seeing readings in the 70s on Monday. Daily high records were challenged up and down the coast as the brilliant sunshine combined with a mass of warm air to take the mercury upward.

Change is on the Way

You are in luck if you are ready to cozy up the fire and enjoy a true taste of fall. The high-pressure that moved into the region from the Desert Southwest will move out and be replaced with cold air coming down from Canada. This will take the temperatures on a dramatic downward trajectory.

The mercury will tumble about 15 degrees in most areas of the East Coast on Tuesday when compared to the weekend’s readings. This will translate to a much cooler Election Day for the region. The good news is that conditions will remain dry, making it easier to get out to the polls without any significant weather disruptions.

The chilly temperatures will be in place through Wednesday for places such as New York City. Although the mercury will begin to inch upward again on Thursday and Friday, it will fall short of reaching the highs that the Big Apple saw over the weekend and on Monday.

Looking Ahead

While the sun will stick around for a few more days, forecasters are warning that what is now Subtropical Storm Nicole is projected to track up the Eastern Seaboard later in the week after unleashing heavy rain and strong winds in Florida. The rain is forecast to move through the Southeast and up the coast into Atlantic Canada by the end of the week and into next weekend.

Precipitation of this magnitude could trigger localized flooding in the Northeast, an area that is in dire need of moisture. Unfortunately, the strong breezes put in place by the high-pressure area coming down from Canada will also create above-normal tides that heighten the risk of beach erosion and coastal flooding. The area most likely to see these impacts include New Jersey and down through the mid-Atlantic.
