Above: High Resolution Ensemble snow accumulation forecast for today.

A low pressure trough approaching New England from the west today will cause snow and rain to spread across Connecticut from west to east this afternoon. Out ahead of the trough, southerly winds will increase across the area to 12-20 mph, with some gusts to 30+ mph. This will push high temperatures into the 35-40 degree range. The precipitation will be mostly snow across northwestern CT and mostly rain across southeastern CT, with a combination of rain and snow elsewhere. The precipitation tapers off this evening, with 1"-3" of wet snow accumulating in portions of western and northern CT - especially across hilly terrain. The highest amounts will be found in the northwest corner of the state. I like the HREF snowfall forecast (pictured above), which is in line with other high resolution guidance. I believe that I-95, I-395, and I-91 between Hartford and New Haven will be primarily wet this afternoon. I wouldn't be surprised if slick spots develop on I-84 between Hartford and Danbury, though. Watch out for icy spots tonight, as skies become partly cloudy and temperatures fall into the 20's.
