Winter Storm Watch Issued For NH: Half A Foot Expected Friday

The National Weather Service has issued a winter storm watch for all of New Hampshire warning of “slick travel conditions” on Dec. 22, 2017, as snow moves into the region. The alert was issued at 3:45 p.m. today. Forecasters expect a low pressure system to move through the Ohio River Valley tonight and then into the Northeast tonight.

“It will continue moving northeast, spreading snow into Maine and New Hampshire, from southwest to northeast, during the mid to late morning hours Friday,” the NWS predicted. “By midday Friday, a weak secondary area of low pressure will form along the southern New England coastline before entering the Gulf of Maine Friday night. This secondary system will keep a chilly northeast flow over the region, keeping the precipitation mainly in the form of snow for our first of three weather systems over the long holiday weekend.”

Late in the day, the snow is expected to pick up intensity, becoming heavy, and lasting through the evening. The precipitation could change to sleet and freezing rain early Saturday morning, especially in southern New Hampshire. Anywhere from 5 to 7 inches of snow are expected by late Friday night.

On Saturday, a second system moves into the region bringing snow and freezing rain which will continue into Saturday night and Sunday morning. Snow is expected to return again on Monday. Slick driving conditions are expected during this time period but snow accumulations are not yet known although some forecasters are predicting 3 to 6 inches on Monday.
