Many locations across the Northeast will feel like mid-November as the weekend progresses with the arrival of colder air and gusty winds.
After a warm and rainy week, a blast of chilly air from Canada will arrive in the Northeast for the weekend. Many locations experienced temperatures between 15 and 20 F above average for this time of year this past week. However, by Sunday many locations will run 5 to 10 degrees below average. The 20- to 30-degree change will be quite noticeable for many people.
Saturday will be transition between the mild air lingering along the Atlantic coast and the chilly air sweeping across the Great Lakes and into the Appalachians. A cold front will sweep through the area during the day Saturday. While a shower cannot be completely ruled out along the Interstate-95 corridor, most showers will occur over the mountains and downwind of the Great Lakes.
The chilly air will settle in Saturday night and Sunday on gusty northwest winds.
According to AccuWeather.com Chief Meteorologist Elliot Abrams, "The cold air will be flowing past Lake Erie this weekend and will be a reminder that Halloween is coming."
Temperatures might even be low enough to see the first snowflakes of the year in some areas late Saturday night into Sunday morning.
According to AccuWeather.com Senior Meteorologist Paul Walker, "Wet snowflakes could mix in with rain showers over the Finger Lakes, Catskills and Adirondacks of New York and the Alleghenies of western Pennsylvania Saturday night."
On Sunday, high temperatures will range from the middle 40s in the interior Northeast to the middle 50s along the coast. However, the combination of temperature, wind, cloud cover, humidity and other factors will cause AccuWeather RealFeel® Temperatures to dip into the 30s and 40s at times.
The November-like conditions will persist over the Northeast into the beginning of next week.
"As the week progresses, the chill will fade," Abrams said.
Depending on the evolution of a storm along the coast of the Northeast, a period of rain and wind may occur in part of the region during the middle of the week.
