As the weekend progresses, brisk and unseasonably cold conditions will settle into the northeastern United States.
In the wake of a front, unseasonably cold air will funnel down from Canada, causing temperatures to drop 10-20 degrees Fahrenheit below normal on Sunday.
On Sunday, temperatures may be no higher than the 40s for cities such as Erie, Pennsylvania; and Buffalo, Syracuse and Watertown, New York.
While the air will modify along its journey to the Northeast coast, highs in the upper 50s and low 60s will be the theme from Boston to Washington, D.C. This is quite the contrast from highs in the 70s late this past week.
Despite some sunshine, the combination of winds, cloud cover, low humidity and other factors will keep AccuWeather RealFeel® temperatures in the 30s and 40s across the Northeast and mid-Atlantic on Sunday.
Brisk northerly winds could gust 20-30 mph at times throughout the day.

Those heading to Sunday afternoon baseball games in Baltimore, New York, Philadelphia and Washington, D.C., may want to consider bringing along a jacket.
Enough cold air will be in place high up in the atmosphere to generate bands of rain showers mainly downwind of the Great Lakes. Even a few wet snowflakes may mix in across the higher elevations.
"Snowflakes are possible over the Adirondacks of New York late Sunday afternoon into Sunday night," AccuWeather Senior Meteorologist Matt Rinde said.
Patchy frost and freezing temperatures will be a concern in the normally colder locations of the interior northeast Sunday night into early Monday morning.
"Interior areas of the Northeast away from large bodies of water and in river valleys are more likely to experience temperatures at or below freezing Sunday night," AccuWeather Meteorologist Michael Doll explained.
He added that a residual breeze would preclude frost formation or a hard freeze in most locations.
Still, area residents who may not have considered the potential for frost this late in the season should take extra precautions to protect sensitive vegetation.
This
graphic depicts the average date of the last frost across the United
States. Most locations in the Northeast have already past their average
date for a last frost."The overall impact to crops already planted should be minimal, but if people want to protect the most tender vegetation than it's a good idea to bring those plants and flowers inside," Doll stated.
The brunt of the chill will only last into Monday before milder and more seasonable conditions return to the region by midweek.

I'm
glad to see the sunshine. It'd be nice if we could have sunshine with
daytime highs flirting with the 80 degree mark, which is more typical
for the middle of May. But I guess if I want to see sunshine around
here, that can't happen.
