Crank up the heater and bring in your plants — temperatures are expected to dip below freezing overnight in Barrington.
A freeze watch is in effect for the Chicago suburbs, including Barrington, from 1 to 8 a.m. Tuesday with temperatures expected to dip into the upper 20s and low 30s for much of the area, according to the National Weather Service. Widespread frost is expected after 2 a.m. and before 8 a.m. in Barrington, according to the NWS.
There is also a slight chance that we may see some very early-season snow on Tuesday with a slight chance of rain and snow after 2 p.m. in Barrington, according to the National Weather Service.
"There has been some computer forecast guidance suggesting that there is a potential for some accumulating snowfall over portions of the area on Tuesday," according to the NWS. "This is certainly not a likely scenario by any means and is currently not in the official forecast."
The last time Chicago saw a snowfall of at least an inch in October was on Oct. 20, 1989 when 1.8 inches of snow fell.
Temperatures will reach a high in the upper 40s for most of the week in Barrington, with the warmest day expected to be Saturday with a high of 50 degrees, and lows will be in the upper 20s and low 30s.
