NYC Area Forecast: Nicer weekend, winter storm possible next week

/by
Friday’s Weather Rating | 5/10 (Fair)

Friday began with a bit of a different tune than the past few days – although it’s cold this morning, it is not quite as blustery and the risk of snow squalls has been reduced. In other words, the air feels a bit less “wintry”, as the airmass itself begins to modify a bit to its surroundings. It’s still quite cold though and honestly, several degrees below average for this time of year, and you can feel it throughout the majority of the Northeast states today.

The weather over this weekend will remain much colder than average for this time of year. Temperatures are forecast by the European model to run several degrees below normal on both Saturday and Sunday throughout the Northeast states, as arctic high pressure redevelops and aids in funneling cold air southward from Canada. This secondary surge of cold air is being driven by the redevelopment of a Greenland Block, which by this point has become a thorn in the side of many, as it has been the impetus for this late season winter weather surge. Low temperatures tonight throughout a large part of the area will fall down into the mid to upper 20’s and may even reach the teens in some suburbs.

NYC Area Forecast: Improving conditions lead us to midweek

Wednesday’s Weather Rating | 4/10

Okay, take a breath.

Three weeks removed from a large-scale pattern change which featured the development of a classic Greenland Block, we have experienced three Nor’Easters, all of which have been impactful in the Northeast states. As we move towards midweek,  much of the Northeast states will finally catch a break. The departing Nor’Easter will leave blustery conditions with a few snow showers and squalls expected, but overall conditions will improve as high pressure builds in.

Temperatures will remain well below normal, and that will be the theme of the next several days – Cold. Much of this can be attributed to the re-development of another Greenland Block during the next few days, as forecast models suggest the pattern will begin to reload. Greenland Block’s are, in their nature, ridges of high pressure over Greenland and the higher latitudes of the Arctic that dislodge cold air further south into Canada and the Northeast States.

Another significant Nor’Easter is set to impact the Northeast states on Tuesday – this time with the worst of the storm passing well east of NYC and impacting Eastern New England. 

The third Nor’Easter in as many weeks (well, technically just over two weeks) is set to impact the Northeast states on Tuesday, bringing widespread impacts from just east of New York City into Long Island and all of New England. This storm’s formation was well underway this morning and it is expected to continue to strengthen through Tuesday morning and afternoon across the Northeast States.

9:00am Tuesday Update: Heaviest banding has shifted east into parts of Long Island and Connecticut, where 700mb frontogenesis has increased over past few hours, with the storm tracking well offshore, as was previously anticipated. Current radar shows actually shows two frontogenetic bands of snow with some subsidence in between over Central Suffolk county and central parts of Connecticut. But these bands will likely merge before finally shifting east by early this afternoon.

Heavy snowfall rates of 1″ to 2″ per hour and perhaps even higher with reduced visibilities may for hazardous driving over next few hours. Snowfall totals over parts of Long Island and CT have been 2″ to 5″. These totals will likely double later this morning, especially over Suffolk County and New London County in CT. Although roads may not receive as much accumulation with surface temperatures between 32 to 34 F.

Current mesoscale analysis from SPC, showing strong 700mb frontogenesis over Long Island and New England.

Elsewhere, over most of New Jersey and the Lower Hudson Valley and Eastern PA snow appears to be winding down. A small moderate band has build back over NYC and extending into the ocean. This should shift east during the next hour. Snow will taper off to snow showers everywhere by around noon. Snowfall totals will likely wind up between 2″ to 5″. Although many paved surfaces, including roads, especially in NYC will likely receive less accumulation, with temperatures now in the mid 30s.

7:00am Tuesday Update: Snow is spreading throughout New Jersey and New York this morning, with light accumulations in many suburbs. Snow is much less likely to stick in New York City proper with warmer ground and pavement temperatures. This light snow will continue for the next few hours before beginning to pull back toward the east, with heavier bands developing towards Long Island and Connecticut.

The difference between this storm system and the past few will largely be the area it will impact. It otherwise parallels the other two storms very closely; it is powerful, rapidly intensifying, extremely dynamic, and will bring a myriad of impacts to the area it affects. The area most strongly affected with this one, however, will be Eastern New England and Long Island, where heavy snowfall and strong winds are likely.

Good morning, we hope you had a great weekend! You can listen to our audio weather briefing from Sunday evening above. 

Sunday was the winner of the weekend weather, with limited clouds and plenty of sunshine underneath a calm and cold high pressure. Despite the cold air overhead, you probably noticed the warm sun – which is becoming increasingly apparent this time of year. We are quickly approaching Spring, after all. The overall weather pattern simply isn’t cooperating just yet.

After two huge Nor’Easters over the past two weeks, we’re expecting our third on Monday and Tuesday. Another powerful cyclone will develop off the coast (beautiful satellite imagery is coming your way!) and bring widespread impacts, this time focused on New England. New York City proper looks to escape the worst impacts of the storm system, as we have been detailing for several days now. But parts of Long Island, Connecticut and Southern New England are likely to experience impacts of more significance.
