Barnstable may see 3 to 7 inches of snow over the weekend, according to the National Weather Service.

The forecast calls for snow and a high near 38.

NWS has issued a Hazardous Weather Outlook for the area with snow showers expected early Saturday morning and steady through the day. 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 advisorires 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.
