Not the Greatest Week Ahead

Sussex County is under a winter weather advisory for possible accumulating snow of a few inches around the morning commute. The highest chances are in the higher elevations of this county.

Elsewhere, even into North-Central New Jersey some wet snow could briefly happen for an hour as the warm air advection precipitation moves in. Also, some heavier shower bursts in the entire region could drag some colder air down to cause some sleet pellets to mix in. Temperatures will be tricky as advecting warmth would cause temperatures rises...BUT evaporative cooling will initially cause a drop once the precipitation begins in parts of the region.

By morning, except the Poconos most areas should just be wet. Roadways will defintely be wet regardless of grassy accumulations in the northern areas.

T-storm chance appears isolated for now in South Jersey as temperatures rises to near 60 could occur in the warm sector. The high-resolution models just don't show the moisture with a cold front...despite some potential instability. This will need to be watched however.

Tuesday now appears dry. However, I still think there will be variable cloudiness. Temperatures behind the cold front will not cool right away as cold air advection lags behind by a day.

The cold front will stall south of our region and become a train track for waves of low pressure to develop along the boundary. If the front moves far enough south, but yet not too far south to cause drier air to hold in place suppressing the moisture, we could have precipitation combine with air just cold enough for frozen precipitation. With the system so far out, more than a mention of mixed precipitation wouldn’t do the situation any justice.

Canadian high pressure on Thursday and Friday will make it feel quite chilly in our region. With some leaves and flowers fooled by the recent warm spell, frost and freezes Thursday Night and Friday may pose some trouble. I am not sure if the growing season has officially begun for many, but the frost and freeze is worth a mention to some interested parties.
