Dedham may see 3 to 5 inches of snow over the weekend, according to the National Weather Service.

NWS has issued a Hazardous Weather Outlook for the area with snow showers expected Friday night and steady snow on Saturday. The steady snow should taper off by 5 p.m. Saturday and then snow showers are expected Saturday night.

The snowy conditions will be joined by fog and winds that may exceed 20 mph.

NWS said there is a “moderate to high probability that winter weather advisories will be needed for a portion of southern New England.”

The heaviest snowfall should hit southeastern Massachusetts, but NWS warned that a shift in the storm track could result in changes in the type of precipitation and amount.
