Chilly, fall-like air will be accompanied by rain and snow showers across the northeastern United States this weekend.
The air will turn cool enough for heaters, blankets, sweatshirts and thick jackets to be needed once again. Enough of a chill will settle in place for a frost to occur in some locations.
Temperatures will average 5 to 15 degrees Fahrenheit below normal, and will be more typical of March or November.
“After a record warm April in many locations throughout the mid-Atlantic and Northeast, the first weekend of May will provide a stark contrast to April’s summerlike heat,” AccuWeather Meteorologist Kyle Elliott said.
A storm that will first douse the region with soaking rain and thunderstorms late this week will put on the brakes this weekend. Chilly air will be funneled southward on the back side of the storm.
“The storm will virtually stall out over northern New England through Sunday, allowing the chilly air to push the entire way to the Interstate-95 corridor and southern mid-Atlantic,” Elliott said.
Temperatures will fail to exceed the 40s to middle 50s F over interior areas by Sunday. Highs will be closer to the 60-degree mark along the mid-Atlantic and southeastern New England coasts.
Brisk winds will drop AccuWeather RealFeel® Temperatures 5 to 10 degrees lower than the actual temperature.
Lows bottoming out in the 30s from the central Appalachians though New York and New England will threaten some communities with a late-season frost.
Those who have planted flowers and vegetation should take precautions to protect sensitive plants. Simple steps such as covering plants or bringing them indoors can keep them shielded from the potentially damaging effects of the chill.
Rain and snow showers will be triggered as the storm sits and spins overhead.
“Snow can fall across the West Virginia, western Maryland and southwestern Pennsylvania mountains on Friday night into Saturday,” AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
Wet snowflakes can mix in with rain showers elsewhere across the interior Northeast, especially during Saturday night.
Those hoping for the return of warm weather will be out of luck anytime soon as damp and chilly conditions are expected to persist into next week.
“It is quite possible that average temperatures in many locations throughout the Northeast end up lower in May than those recorded in April,” Elliott said.
Elliot does not expect near- to above-average warmth to return to the region until the third and fourth weeks of May.
