NYC Weather Update – Jan 25, 2021

A long duration but light impact winter weather event is forecast to hit Tuesday and Wednesday. Since last week, the track of this storm has shifted north, resulting in warmer air present near the coast. This will result in wintry mix and little to now accumulating snow. We miss out on a more potent storm later in the week which will move well offshore of the area. Temperatures throughout the period remain below normal in the mid-30s at best, with a reinforcing blast of cold air late in the week.

Rest of today – mostly sunny with high temperatures in the upper-30s. Clouds increasing overnight with low temperatures around 30ºF.

Tuesday – mostly cloudy with high temperatures in the mid-30s. Periods of light wintry mix/snow during the day as a couple of modest low pressure centers impact the area. Light accumulations expected, probably around half an inch. Overnight lows steady in the mid-30s with rain/snow mixing possible.

Wednesday – rain/snow mix possibly extending into Wednesday morning. High temperatures in the upper-30s. Any accumulated wintry precipitation should melt rather quickly. Overnight temperatures dropping into the low-30s.

GFS model surface precipitation and 1000-500 mb thickness for 7AM Thursday. A potent storm is seen exiting east well offshore from NYC.

Thursday another low pressure, center, much stronger than the ones associated with the early week develops and tracks well south of us. High temperatures in the mid-30s. The main impact of this storm for us will be the stiff winds it produces as it continues to deepen and the pressure gradient around it tightens. These winds will also be from the northwest, bringing in a colder air mass. Overnight lows in the low-20s as a result.
