Tranquil conditions will be in place today.  A powerful cold front and a wave of low pressure will bring heavy rain, strong winds, and snow tomorrow into Monday morning.

TODAY

High pressure will exit the region with increasing clouds.  Winds will be from the south at 5 to 10 mph.  Temperatures will rise into the lower to mid-50s for highs.

TONIGHT

As a cold front approaches, clouds will increase with winds from the south at 5 to 15 mph.  Temperatures will fall into the lower to mid-30s away from the coast and mid to upper 30s on the immediate coast for lows.

TOMORROW

An area of low pressure and cold front will approach, with showers developing in the morning and becoming widespread in the afternoon.  Winds will increase from the south at 10 to 20 mph, with gusts over 30 mph.  Temperatures will rise into the upper 50s to lower 60s over the interior and lower to mid-60s along the coast for highs.

TOMORROW NIGHT

The cold front will press through the region as the wave of low pressure intensifies while moving along the New Jersey coast with waves of heavy rain and embedded thunderstorms.  Meanwhile, the rain will change to snow just behind the cold front as temperatures rapidly crash over northeastern Pennsylvania, the Hudson River Valley, and northwestern New Jersey.  Snow accumulation will start, initially on cold surfaces, for elevations above 1,500 feet.  Winds will be from the south at 10 to 20 mph with gusts up to 60 mph ahead of the cold front and within thunderstorms, and then veer to the northwest at 10 to 20 mph with gusts up to 40 mph.  Temperatures will peak in the upper 50s to lower 60s ahead of the cold and then rapidly crash through the 50s, 40s, and 30s.

MONDAY

The low-pressure system and cold front will push east and northeast in the morning, with rain mixing with and changing to snow along the coast and snow continuing in the higher elevations.  The snow below 1,000 feet and along the coast will accumulate on some cold surfaces but quickly end by 10 AM.  Winds will veer from the south to the northwest at 10 to 20 mph, with gusts between 20 to 50 mph in the morning.  Winds will be from the northwest at 10 to 20 mph in the afternoon.  Power outages and wind damage will be a threat in the early morning.  Temperatures will fall from the 50s and 60s early in the morning into the 40s, 30s, and 20s by the afternoon.
