Update: Ice causing slick roadways will change to rain this afternoon
The passing storm system will bring moisture to the Granite State but most will see less than 1 inch of total snowfall. Northern reaches of Grafton County, the White Mountains, and the Great North Woods may see more acclimation of wet slushy snow accumulation but mostly in higher elevations. Even in those areas snow could mix with or change over to rain.
A freezing rain advisory is in effect for Cheshire, Sullivan, Southern Grafton, Carroll, Belknap, Merrimack, Hillsborough, Straford, and interior Rockingham counties from 10 a.m.-5 p.m. Sunday. A trace of ice is possible due to some freezing drizzle. Be mindful of slippery spots.
A winter weather advisory is in effect for Northern Grafton and Coos Counties from 1 p.m. Sunday to 1 p.m. Monday. Around a trace of ice accumulation is possible along with wet snow accumulation anywhere from 1 to 6 inches, with elevations above 2,500 feet seeing the most snow.
The bulk of the moisture with this storm system starts working in after noon unday. Several locations could see some light snow, sleet, or freezing drizzle late Sunday morning into the early afternoon but this does not look to amount to much. As the day progresses, temperatures clime and any freezing rain will change to plain old rain.
By Sunday night, most of the Granite State will be seeing rain, and it could be heavy at times. Several locations could see up to 1 inch of total rainfall. Rain will taper after midnight.
The storm system will move off to our northeast and cold air tracks in behind it. This may allow for a change back to all snow for folks across northern New Hampshire overnight Sunday into first thing Monday morning. Several inches of snow accumulation will be possible during this period. To the southern part of the state, most could see a dusting of snow into early Monday.
Skies will slowly clear with breezy conditions as we go past sunrise Monday.
