MONDAY Night update: The forecast calls for high wind gusts and drifting snow Monday evening, with a cold front sweeping over New Hampshire for the coming days.

The National Weather Service has a hazardous weather outlook for the region. A combination of strong winds and cold will mean a chance of dangerous wind chill values through the end of the week, the Weather Service says.

MONDAY UPDATE:  The National Weather Service has issued a blizzard warning for eastern New Hampshire, along the coast and parts of Rockingham County.

A winter storm warning remains in effect for the rest of the Granite State.

For the blizzard warning, snow will fall heavily through early afternoon, visibility will be limited for motorists, and wind gusts are expected to pick up during late afternoon and early evening, according to the National Weather Service.

Snow will continue to fall across the state with accumulations of an additional two to four inches likely by night-time. Temperatures will remain below freezing.

Tonight, snow will mix with freezing rain in southern parts of the state, with total accumulations of four to eight inches expected. Overnight temperatures will drop to the mid-teens ranging to the mid-twenties further south.

On Saturday, the forecast is calling for a mix of snow, sleet, and freezing rain, making travel difficult. The storm will continue through Saturday night, with clearer conditions expected for Sunday.
