As expected a nasty evening of weather has developed in the hilltowns of northwest and northeast of Hartford. Temperatures have dropped below 32F in many elevated spots thanks to a steady supply of colder and dry air beings drawn south by a developing low just south of Connecticut.
This northerly drain of cold will continue through the evening and the freezing rain will continue. Thankfully, ice accretion should be less than 1/4 inch which is generally the threshold at which trees and power lines can begin to see damage.
For areas with temperatures above freezing it's a cold rain with occasional sleet pellets. I do think there will be some slick spots lingering in the hills tomorrow morning - don't be surprised if we see some school delays.
