Memorial Day to be colder than Christmas for millions in 8 US states
Temperatures across the Northeast and Mid-Atlantic are expected to be colder than during Christmas 2025. New York, New Jersey, Pennsylvania, Delaware, Maryland, and parts of Connecticut, Virginia, and West Virginia are forecast to fall into the low to mid 50s on Saturday, about 15 to 20 degrees below typical Memorial Day weekend averages. Major cities such as New York, Philadelphia, and Washington, DC are expected to struggle to exceed recent holiday highs, with Washington predicted around 57 degrees. A major holiday weekend storm will bring steady rain through Sunday, with up to two inches possible in parts of Vermont, Massachusetts, Rhode Island, Ohio, and Kentucky. The cold front is driven by cooler, less humid air from Canada, and cold air damming traps it against the eastern side of the Appalachians, keeping it over the region and affecting nearly 50 million people. Poor conditions may disrupt outdoor plans, cause airport ground stops, and reduce road visibility.
"Those in New York, New Jersey, Pennsylvania, Delaware, Maryland and portions of Connecticut, Virginia and West Virginia will drop in the low to mid 50s on Saturday. This is 15 to 20 degrees Fahrenheit below the normal average for Memorial Day weekend, often called the 'unofficial start to summer.' AccuWeather meteorologists noted that the weekend is expected to be so cold, major cities such as New York, Philadelphia and Washington DC will struggle to beat the high temperatures from last Thanksgiving and Christmas."
"The forecasted high on Saturday in Washington has been predicted to be 57 degrees. In December, it was 60 on Christmas Day in the nation's capital. The major cooldown in the east will also be accompanied by a massive holiday weekend storm, slamming even more states with steady rain through Sunday. Vermont, Massachusetts, Rhode Island, Ohio and Kentucky are also expected to be in the path of this weekend downpour, which will drop up to two inches of rain throughout the region."
"AccuWeather warned that the poor weather will likely impact outdoor plans, cause ground stops at airports and impair visibility on roads. The poor Memorial Day forecast has been fueled by a strong cold front pushing cooler, less humid air down from Canada and across from the Midwest. This air mass quickly replaced the recent summer-like warmth that brought a major heat wave to the East Coast just five days ago."
"This shift is called cold air damming, when cool air gets trapped against the eastern side of the Appalachian Mountains. Since the mountains block the cold air from moving east easily, it piles up and stays in place over the Northeast, dropping temperatures for nearly 50 million people from Washington to Boston. The widespread cooldown has been a shocking reversal from earlier in the week, when"
