PM All Zones Update: Wintry precipitation slides south

/by

Fair and relatively mild weather remained in place this afternoon throughout the majority of the forecast area. Temperatures in the 40’s were fairly common and a mix of sun and clouds made for a pleasant day. A more complex situation will develop from later tonight into Saturday, however, as a temperature gradient to our southwest shifts towards the East Coast.

Colder air will move into the Northeast tonight and into Saturday morning with a very impressive surface high pressure area shifting over New England. Precipitation along the temperature gradient in the Mid Atlantic states will fall as a wintry mixture — with freezing rain, sleet, and rain all possible by Saturday afternoon.

PM Zones Update: Clouds increase, unsettled midweek

/by

After a calm and cold pattern settled into the area over the last 24 hours, clouds began building into the area this afternoon and evening ahead of a developing storm system well to the west of the entire region. This storm will continue building over the next 12 hours, through Tuesday, over the Central United States. A more unsettled weather pattern will build towards the area as the week goes on, with precipitation approaching the area by Tuesday evening.

Much of this precipitation will fall in the form of showers and rain throughout the area, with the potential for some snow and freezing rain over the far interior. In Southern and Central NJ, Long Island and Connecticut zones, however, southerly winds will have taken over the atmosphere before any frozen precipitation can form.

PM Zone 3 & 7 Update: Freezing rain expected Tuesday PM

/by

Increasing clouds this evening will continue building tonight, as a large and complex storm system develops over the Central United States. The hallmark of this storm system, in our area, will largely be southerly winds and warming temperatures in the atmospheres mid and upper levels. However, stout cold air near the surface will lead to the potential for freezing rain on Tuesday evening in the interior and higher elevations.

While southerly winds build in the atmospheres mid and upper levels, where snowflakes form and fall, temperatures at the surface are forecast to remain quite cold even as precipitation begins to fall late on Tuesday afternoon and into the evening and overnight period. This creates concern for freezing rain in the higher elevations and areas with deeper snowpack, with rain falling and refreezing on the surface for a period of time on Tuesday evening.

All Zones AM Update: Cold morning, warmth on the way

/by

Impressively cold air settled in to the area this morning with temperatures falling below zero in many locations. This occurred at the typically favorable radiational cooling locations such as the Pine Barrens and Central/Eastern Long Island. Westhampton Beach dropped to -9F shortly after sunset, which is extremely impressive even for this time of year! Most other areas saw single digit lows, with temperatures predictably remaining warmer in the city and other urban locations.

Temperatures will remain quite cold today with an arctic high pressure still hanging on to control of the weather pattern. Blustery winds will have calmed down this morning and afternoon, and the day is expected to be pleasant overall. Plenty of sunshine will dominate the skies early with no precipitation impacts anticipated — with a gradual trend towards more cloud cover as the day goes on. The biggest threat may be black ice which could have formed on some area roadways.
