Ice, freezing rain alerts expand to 10 N.J. counties. Wind advisory issued for 50 mph gusts Monday.

Winter weather advisories have been expanded to 10 New Jersey counties with freezing rain that could cause a dangerous layer of ice tonight.

The National Weather Service has also issued a wind advisory for 16 counties Monday with up to 50 mph gusts possible.

The more immediate concern is freezing rain already hitting the state Sunday evening.

Winter weather advisories for Bergen, Essex, Hudson Passaic and Union counties expire between 10 p.m. and midnight.

Winter weather advisories for Hunterdon, Morris, Somerset, Sussex and Warren counties take effect at 6 p.m. and run through 2 a.m.

As temperatures remain near or below freezing across northern New Jersey this evening, precipitation will fall as freezing rain, particularly in Warren and Morris counties where a glaze to one-tenth of an inch of ice accumulation is possible.

The National Weather Service warns that even areas outside the advisory that remain near freezing at the onset of precipitation could experience localized icing, especially on shaded surfaces that have remained below freezing for more than 36 hours.

Temperatures will rise above freezing areawide during the pre-dawn hours Monday as a warm front lifts through the region, changing any remaining freezing rain to plain rain.

A brief break in the rain is likely prior to daybreak Monday.

The warm front will be quickly followed by a strong cold front Monday afternoon, bringing another period of rain that may be moderate in intensity at times.

High temperatures Monday will reach the upper 40s along the coast before the cold front passes, bringing high winds to the area.

The wind advisory for 16 counties runs from 10 a.m. Monday to 1 p.m. Tuesday. Just Bergen, Essex, Hudson, Passaic and Union counties are not under wind advisories.

“Strong westerly winds develop Monday with wind gusts up to 50 mph and a wind advisory has been issued,” the weather service said Sunday evening. “Some tree damage and power outages possible.”

Tuesday will be markedly colder with high temperatures struggling to rise above freezing even at the Jersey Shore.

Wind chills in the teens and low 20s are expected during the day.

Skies will be partly cloudy with continued gusty winds of 20 to 30 mph.

Wednesday brings slightly milder conditions with highs in the mid 30s to near 40 degrees, though it remains well below normal for late December.

The extended forecast shows below-normal temperatures continuing through the end of the week and into the New Year.

Thursday may bring a chance of snow showers as a weak cold front passes through, though accumulations are expected to be light.

Friday looks dry with highs in the low to mid 30s.

Another weather system may impact the area late next weekend, potentially bringing a mix of rain and snow, though forecast confidence remains low for that timeframe.
