Winter Weather Advisory in Effect From 9 p.m. Tonight Until 9 a.m. Saturday

Source: NH1 Chief Meteorologist -

A Winter Weather Advisory is in effect from the National Weather Service for all of the Granite State with the exception of far eastern Rockingham County from 9 PM tonight through 9 AM Saturday.

Look for light snow to overspread most of the state late tonight, mixing with and changing over to sleet and freezing rain once we get past midnight. For the Seacoast, things pretty much stay all rain here. For the transition from snow to sleet/freezing rain, that will occur soonest across southern reaches of the state, latest as you work your way north.

Shortly after sunrise Saturday, most should see temps just above freezing with plain rain, but folks across the northern lakes, Mountains, and Great North Woods will likely still be dealing with frozen precipitation. It may not be until early afternoon that we see a transition to plain rain here. Roads, sidewalks, and driveways will definitely become slick overnight into first thing Saturday Morning. Once we get into the late morning into the afternoon, temps will rise above freezing with plain old rain to help melt away slick spots.

For accumulations, snow should be on the order of 1"-3" for the Central Merrimack Valley and points north and west, with 3"-6" across the Mountains and Great North Woods. Less than an inch for far southern reaches of the state with little or nothing expected for the Seacoast.

Ice looks to be on the order of 0.10"-0.25" for the Upper Valley, Central Merrimack Valley, and Lakes where we may see the longest period of freezing rain. Lesser amounts of ice north of there because things may stay snow longer here, and lesser amounts of ice south because of the transition to rain happening much sooner.
