The National Weather Center predicts the first frost of the season is expected for tonight.
A frost advisory for a portion of the state goes into effect at 2 a.m. Saturday and runs until 9 a.m.
"The calm wind combined with a clear sky and dry air in place will allow temperatures to drop to frosty levels," Channel 3 Meteorologist Mark Dixon said.
Temperatures are expected to drop to lows in the upper 20s and lower 30s inland and into the upper 30s to near 40 along the coastline.
"For the areas of interior Connecticut where the growing season has not ended, a Frost Advisory has been posted," Dixon said.
Farmers said they were worried the frost will be on pumpkins across Connecticut on Saturday morning.
"It's that time of year you cant fight mother nature," farmer Tod Scott, of East Lyme, said.
Farmer Becky Scott, of Waterford, said she planned on keeping her pumpkins, gourds and potted plants safe with a very thin cloth, almost like a blanket of protection.
Tom Scott prepared to lose rows and rows of tomato plants, along with summer squash that is continuing to bloom.
"Most of it will be fine because its right next to the ground," Tom Scott said. "But, the stuff that's still growing. The summer squash is still growing. We will lose that and we'll probably lose the tomatoes."
Meteorologist Mike Cameron said anyone looking to do some leaf-peeping may want to head out on either of the weekend days. Some high color is expected in northwestern Connecticut. Peak color remains north of Massachusetts, but are expected to creep into Connecticut soon.
However, a storm system will be on the approach and clouds could overspread the state late in the day on Sunday.
