Residents of the northeastern United States can officially say goodbye to summer. AccuWeather meteorologists say typical fall temperatures and the risk of frost are in the offing for the region into next week.
A sweeping cold front on Thursday brought rounds of rain and gusty showers to many areas across the Northeast, setting up an abrupt change in temperature across the region on Friday, the first full day of fall. In some areas, it was so cold that it felt more like winter than fall.
Conditions were cold enough for some snow in portions of northern New York and New England early on Friday. Some of the highest peaks of upstate New York, including around Whiteface Mountain in the Adirondacks, received snowflakes and even light accumulations.

The coldest air in months is likely to settle into the region Friday night and early Saturday morning.
Widespread temperatures across the Northeast are expected in the 30s and lower to middle 40s across the interior of the Northeast and into New England. A low temperature of 39 degrees is expected in Binghamton, New York.
Closer to the Eastern Seaboard, milder conditions are likely to keep temperatures in the upper 40s or even in the 50s early on Saturday morning.
"Patches of frost will be possible early Saturday morning across portions of southern New York to eastern Ohio and West Virginia," said AccuWeather Senior Meteorologist Dave Dombek.
More urban locations are likely to stay warm enough to avoid frost. However, more remote locations, especially the normally colder spots, could be at risk.
Dombek further explained that frost arriving this time of year is quite normal for the interior Northeast. Even still, experts say it could bring an end to the growing season for some local gardeners. Plants sensitive to frost or colder conditions should be covered or brought inside.
As the weekend progresses, typical fall conditions are expected to persist. Saturday is set to feature mainly dry weather with temperatures in the 50s and 60s in the afternoon.
For these cities, temperatures in the upper 60s and lower 70s are within a few degrees of normal for the final week of September.
With low humidity and light winds forecast for northern New England, it'll be a comfortable day for spending time outdoors, forecasters say.
The mostly dry conditions won't last all weekend in the region. A storm moving in from the Midwest is set to bring a change to parts of the Northeast for the second half of the weekend.
Widespread showers are likely to push into the area Saturday night, bringing in more clouds and keeping temperatures a little higher, which will minimize the risk of frost. The mild and showery weather is forecast to linger into Sunday.
"Ahead of the showers reaching the Interstate 95 corridor later in the day, warmer conditions can be expected on Sunday," Dombek said.
As the front pushes through the area Sunday night, cool conditions will again return to the entirety of the Northeast by Monday and keep any summerlike warmth at bay into the middle of next week.
