While some parts of the country are already seeing the first signs of winter, with snow falling on mountain passes in Wyoming and Montana, for residents of the Northeast, the next season is on track with warnings issued by the National Weather Service. means some changes to
NWS offices in New England and New York are participating in an experimental program that they hope will simplify when cold weather warnings are issued and in-season shutdowns are issued.
Freeze warnings are generally issued when temperatures are expected to drop below 32 degrees. A frost advisory is usually issued when temperatures are expected to drop to the mid to high 30s and a thin layer of ice is expected to form.
Some of the 48 contiguous US states have already issued these warnings, including areas where temperatures are expected to drop near or below freezing, such as Montana and Wyoming.
The cold air even brought snow to the trails over 9,000 feet.
“It’s not unheard of for snow to fall this time of year. It may be a little earlier than usual, but we’re expecting a warmer next week and the snow will melt,” said an NWS meteorologist in Wyoming.

Cold snaps not only mark the change of season, but also the end of the growing season.
If the air cools enough, the cells inside the plant can freeze and form ice crystals, according to agriculture experts. The crystals then break through the cell wall and damage the plant.
Because cooldowns occur annually, the NWS office issues alerts such as Freeze Watches, Freeze Warnings, and Frost Advisories designed for the agricultural industry and those with backyard vegetation.
Each agency has its own approach to when to end its growing season recommendations, and the Japan Meteorological Agency admits that the lack of uniformity is confusing.
“Collectively, all the offices in New York and New England have come together and said it makes more sense to just go to a date where nothing is growing climatologically,” Buffalo’s NWS Warning Coordinator said. Mike Fries, a meteorologist, said, New York.
When can we expect the first snow of the season?
The experience program will stop issuing alerts approximately 10 days after the region’s normal freeze date.
“Our goal is to streamline the freeze/freeze process with defined cut-off dates, which facilitate and assist users in their planning decisions,” said Fries.
In northeastern locations, the average first significant cold snap of the season is just weeks away.
Many areas reported seeing their first freeze in late September/early October.
