Philadelphia, Pennsylvania — Residents across the Northeast are preparing for another dramatic weather shift as unusually cold temperatures move into the region just ahead of Memorial Day weekend, bringing conditions forecasters say may feel more like Thanksgiving than the unofficial start of summer.
After experiencing intense early-season heat over the past week, many areas are now bracing for chilly temperatures, steady rain and gusty winds that could disrupt outdoor holiday plans.
Northeast Hit by Dramatic Weather Whiplash
Meteorologists say the region has been stuck on a “temperature roller coaster” this spring, with extreme swings between record highs and lows occurring within days of each other.
Just days after temperatures climbed into the 90s along the Interstate 95 corridor, a sharp cooldown swept into the Northeast, dropping temperatures into the 50s and 60s by Thursday afternoon.
“The seemingly endless temperature roller coaster this spring will continue through the Memorial Day holiday with another sharp cooldown across the northeastern quarter of the nation,” a meteorologist said.
The dramatic change has been especially noticeable in Philadelphia, where residents recently endured the city’s first heat wave of the season.
Philadelphia Forecast to Feel Like Thanksgiving
Philadelphia reached 98 degrees on Tuesday, marking the highest temperature ever recorded in the city during May. However, by Saturday, temperatures were expected to remain stuck in the 50s all day, with rain and wind making it feel even colder.
Forecasters warned that the Temperature could dip into the 40s, creating conditions far more typical of late November than late May.
“Put another way, the weather on Saturday in Philadelphia will be more typical of Thanksgiving than of the Memorial Day weekend.”
The unusual cold snap has left many residents shocked after just recently dealing with summerlike heat.
Pennsylvania Town Could Set New Cold Record
The weather swings have been equally dramatic in other parts of Pennsylvania.
State College recently went from a 49-degree high on May 14, which was an all-time low for the date, to nearly 90 degrees on May 18 just four days later.
Now, forecasters say the area could once again challenge historic records, with Saturday’s expected high of 48 degrees potentially becoming the lowest ever recorded for that date.
Reliable weather records in Philadelphia date back to 1872, while records in State College have been kept since 1893.
Cold Canadian Air Mass Driving the Chill
Meteorologists say the latest blast of chilly weather is being caused by a strong cold front pushing down from Canada.
The cold air mass is expected to linger due to strong areas of high pressure positioned near Atlantic Canada and off the East Coast.
“For some areas across the interior of Pennsylvania where there is a steady rain falling all day Saturday, RealFeel Temperatures may struggle to reach 40,” forecasters said.
The cold pattern has also increased concerns about late-season frosts and freezes in parts of the Northeast.
Frost Threat and Rain Could Disrupt Holiday Plans
Forecasters warned that temperatures near or below freezing could threaten vegetation across parts of upstate New York and northern New England Friday and Saturday mornings.
While southern areas are not expected to see freezing temperatures, the combination of cold rain and wind could impact beach outings, pool openings and other Memorial Day activities.
Ironically, some of the warmest weather in the Northeast this weekend is expected in northern New York and parts of New England before wetter conditions return by Sunday and Monday.
When Will Warmer Weather Return?
Meteorologists believe temperatures should begin rebounding closer to normal levels by the middle of next week, with highs returning to the mid- to upper 70s in many areas.
However, forecasters say people hoping for another round of 90-degree heat may need to wait.
