It's not even Halloween yet, but we could have our first snowfall of the season tonight.
According to the National Weather Service, Lexington could have as much as one-inch of snow accumulation by this time Friday morning.
The NWS is expecting a 100 percent chance of precipitation Thursday—rain during the day, snow at night.
And with the potential for white stuff comes a "freeze watch" by the NWS for southern Middlesex County, including Lexington.
The freeze watch is in effect from tonight until early Friday morning as temperatures are expected to fall into the upper 20s or low 30s.
According to the NWS, a freeze watch means that "sub-freezing temperatures are possible [and] these conditions could kill crops and other sensitive vegetation."
There's also a chance of snow showers on Saturday night, the Service says.
