Forecast: Monday the start of a long awaited warmup

Partly cloudy skies are expected early Monday, behind a disturbance in the mid levels in the atmosphere which will move through the area overnight and early Monday morning. Rising heights aloft by afternoon, however, will allow for clearing and mostly sunny skies during the day. Temperatures will rise by afternoon, into the 60’s and lower 70’s especially across Central and Northeast New Jersey as well as New York City. After several days of below normal temperatures to begin spring, the warm air will feel all the more pleasant.

At noon time on Monday, temperatures generally should be from the upper 60’s to low 70’s across New Jersey — and in the 60’s along the coastline with slightly cooler temperatures across Eastern Long Island and the NJ Coast.

A seabreeze is expected to develop by late afternoon, however, owing to developing southeast winds. The wind direction will usher in a marine layer off the cool ocean waters which will serve to cool temperatures down by afternoon across Long Island and New Jersey Shore. By late afternoon, the seabreeze should make some westward progress towards New York City and Northeast New Jersey as well. Some clouds and drizzle are expected Monday evening, with the potential for showers and even a rumble of thunder into Tuesday morning. The showers will form thanks to a weak low pressure system which will be riding along an approaching warm front. This warm front is important — it passes our area by Tuesday and will bring the potential for even warmer temperatures (near 80!) across parts of the area Tuesday afternoon.

The forecast becomes a bit more complicated from the middle of the week into the tail end of the week, with model guidance struggling to pinpoint the location of a warm front. The positioning of the front will have drastic implications on our weather — just a few miles could make a 10 to 20 degree temperature difference! For now, it appears most models are in good agreement that the warm front will clear our area to the north.
