Weak low pressure moving through the region today will bring the threat of snow, ice, rain, and much colder temperatures with it. High pressure will quickly build in afterward bringing dry conditions and seasonably cooler temperatures through Tuesday before another winter weather threat looks to return by the end of the work-week.
TODAY
A redeveloping area of low pressure will bring mixed precipitation to the region. Heavier rain showers will likely develop along the coast in the afternoon with snow and sleet developing along and to the north of the I-80 corridor. Accumulating snowfall will favor the higher elevations including the Poconos, Catskills, the Hudson Highlands, and the Hudson River Valley. Generally speaking, 1 to 3 inches is expected north of the I-80 corridor, with 3 to 6 inches possible for locations above 1,000 ft of elevation (Refer to the map below for further details). Be prepared for slippery roadways and other untreated surfaces. Temperatures will rise into the lower to mid-30s over the northern portion of the interior, upper 30s to lower 40s over the southern portion of the interior, and mid to upper 40s along the coast. Winds will be from the east at 5 to 15 mph.
TONIGHT
Periods of snow will continue throughout northeastern Pennsylvania, the Catskills, the Hudson River Valley, northwestern New Jersey, and Connecticut. Rain showers could switch to snow or sleet over parts of central to southern New Jersey and the Philadelphia metro area. Temperatures will fall into the upper 20s to lower 30s in the Poconos and Catskill region, with low to mid-30s expected elsewhere. Winds will back to the northeast at 5 to 15 mph.
TOMORROW
Lingering showers over parts of northern and eastern New Jersey are possible in the morning with cloudy skies elsewhere. High pressure will build in and skies will gradually clear into the evening. Winds will slightly back from the northeast to the northwest at 5 to 15 mph. High temperatures should rise into the mid to upper 30s over the interior and upper 30s to lower 40s along the coast and in the Delaware River Valley.
TOMORROW NIGHT
Skies will continue to clear overnight with much cooler air working into the region. Temperatures will fall into the upper teens to the lower 20s in the Poconos and Catskills region, lower to mid-20s over the interior, and upper 20s to lower 30s along the coast.
TUESDAY
High pressure will produce generally sunny skies across the region, with winds from the northwest at 5 to 15 mph. High temperatures will range in the low to mid-30s over the interior and upper 30s to lower 40s along the coast and in the Delaware River Valley.
WEDNESDAY
High pressure will exit the region with cloud cover expected to increase throughout the day. Low temperatures will range from the upper 10s to the lower 20s over the interior, mid to upper 20s in the Delaware River Valley, and upper 20s to lower 30s along the coast. High temperatures will range in the lower to mid-30s over the interior and upper 30s to lower 40s along the coast and in the Delaware River Valley.
THURSDAY
An area of low pressure should approach the Tennessee River Valley with precipitation developing by the evening. High uncertainty exists surrounding the timing, intensity, accumulations, and overall evolution of this system. For now, rain showers seem likely in the afternoon along the coast and a wintry mix of snow, sleet, and rain will likely develop over the interior with precipitation potentially becoming heavy at times. Low temperatures will range in the 20s over the interior and lower to mid-30s along the coast. High temperatures will range in the mid to upper 30s over the interior and lower to mid-40s along the coast and in the Delaware River Valley.
FRIDAY
The area of low pressure will redevelop over the coastal waters with showers expected throughout the day. Periods of snow, heavy at times, seem likely over the interior and northwestern suburbs of the I-95 corridor, with a wintry mix of snow, sleet, and rain around the I-95 corridor and rain east of the I-95 corridor. Low temperatures will range from the lower to mid-30s over the interior and upper 30s to lower 40s in the Delaware River Valley and along the coast. High temperatures in the lower to mid-30s over the Poconos and Catskills, lower to mid-40s over the rest of the interior, and upper 40s to lower 50s along the coast are expected.
SATURDAY
The low-pressure system will slowly depart and any lingering rain showers could possibly change over to snow. At this time, it is too soon to confidently say exactly when and where the heaviest precipitation and accumulating snowfall will occur. Low temperatures will range from the low to mid-30s over the interior and upper 30s to lower 40s along the coast. High temperatures should range in the mid to upper 30s over the interior and lower to mid-40s along the coast and in the Delaware River Valley.
SUNDAY
Scattered cloud cover is expected throughout the region, with low temperatures ranging in the upper 10s to the lower 20s over the interior and upper 20s to lower 30s along the coast. Expect high temperatures in the upper 20s to lower 30s over the interior and mid to upper 30s along the coast and in the Delaware River Valley.
