Late Thursday, snow will start. NWS reports that Confidence in snowfall amounts over 6 inches is growing at this time. If it tracks further south, less snow will develop. A track further north will result in more snow.
A Winter Storm Watch has been issued for most of the state starting Thursday evening through Saturday morning by the National Weather Service. Late Thursday night, light snow will begin to develop across the region, generally after 2am-4am. Snow accumulation will be light with an inch or less expected for most areas, although northern NH may see 1-4 inches.
The National Weather Service is indicating 6 inches or more are possible for southern New Hampshire. On Friday and through the day Saturday, two systems will phase together over the region with moderate to heavy snow developing across much of the region on Friday and lasting into Saturday.
The expectation is for dry snow when the system initially begins late Thursday night and early Friday morning. Snow will gradually trend toward normal snow through the day Friday and may become wet Friday afternoon and evening, mainly in areas south of the Lakes Region. Snow will gradually transition back to normal consistency for southern areas and dry for northern areas Friday night and Saturday. Snow will gradually wind down during the day Saturday as high pressure moves in. Dry conditions are expected region wide by Saturday evening or overnight.
Winds will be gusty with this system starting Friday night into Saturday, with gusts around 25-40 mph likely. Isolated higher gusts around 40-50 mph may occur along the immediate New England coast before winding down later Saturday.
The town of Londonderry is indicating that total accumulation of 6 inches to 18 inches is looking more likely through the event, depending on where the heaviest snow bands set up.
The Londonderry Police Department is asking residents not to park in roadways so snow plow crews can keep roads clear during this snow event.
