Main weather headline to start the week will be a potent and slow-moving coastal storm bringing a variety of hazards to the region later today through tomorrow morning. This storm is the same one responsible for this weekend’s deadly tornado outbreak down south. Conditions improve dramatically towards mid-week.

Rest of today – a flood watch, coastal flood advisories, and high wind warning are in effect mostly through tomorrow morning. Cloudy with high temperatures steady around 40°F. Winds continue to increase throughout the day as a strengthening coastal low approaches and the pressure gradient between it and a high pressure center over Quebec tightens. A low-level jet will enhance winds. Sustained east and northeast winds of 30-40mph with gusts between 50-60mph will become commonplace late today and overnight. The strongest winds will occur closest to the coast.

Along with the strong winds, periods of heavy rain will bring the potential for 1-3″ of precipitation, which could lead to minor to moderate urban and small stream flooding. Timing of the onset of rain will be around 3pm this afternoon.

The persistent and strong northeast winds off the water will contribute to minor to moderate coastal flooding. This will be exacerbated during a couple of high tide cycles.

Tuesday – rain and wind abate during the day, tapering off by the afternoon. High temperatures about the same as today in the low-40s.

Wednesday – as the coastal storm continues to pull away, temperatures rebound and mostly sunny skies return. High temperatures anticipated around 50ºF.

Thursday – another nice day with high temperatures in the upper-40s and mostly sunny skies.

We get a round of light rain late today and overnight. Temperatures warm up Saturday, then moderate Sunday as a storm system approaches from the southwest. Temperatures will remain above normal as this storm system looks set to bring soaking rains Sunday and Monday.

Rest of today – cloudy, with light rain arriving around 3PM and lasting till about midnight. Temperatures will drop from the mid-40s to low-40s overnight.

Saturday – warm, mostly cloudy, with high temperatures in the mid-50s.

Sunday – chances for rain increase in the afternoon. Mostly cloudy otherwise with a high in the upper-40s.

Monday – a low pressure system will be moving off the shore of North Carolina and Virginia. With this strengthening low and a high pressure center over Quebec, a tightening pressure gradient will build resulting in steady and increasing winds. Rain and wind will be constant on Monday with high temperatures in the mid-40s.

Drought Update

Recent storms have brought beneficial rains and snows to the region, but a drought continues, especially in the downstate area. This next storm should continue to help alleviate the drought here.

The beginning of the weekend will be marked by a return to seasonable temperatures after the warm spell we just experienced. Temperatures moderate for the second half of the weekend reach back into above normal territory to start next week.

Rest of today – temperatures dropping from the mid-40s into the mid-20s overnight. Clouds increase as a frontal system far to our south begins to influence our weather.

Saturday – high temperatures only in the low-mid 30s. A small chance of snow in the afternoon though we’re really only on the fringe of the area of influence of a largely stationary front far to our south. Mostly cloudy skies otherwise.

Sunday – skies clear and temperatures rise back up to around 40ºF. High pressure continues to build and move east, allowing winds to turn to the south and southwest bringing warmer air our way.

Monday (MLK Day) – should be a pleasant day for anyone who’s out volunteering on this holiday. Sunny with high temperatures in the low-40s.

The latter half of this week will bring welcome relief from a period of below average temperatures. Temperatures will rise well into the 50s by the end of the week. Winter returns for the weekend as temperatures fall back to seasonal levels.

Rest of today – there are some light snow showers far west of the city. Some of this might make it to the city, with a chance for snow and wintry mix and a high around 40ºF.

Wednesday – overnight, temperatures barely drop, while a storm system moves through. A chance of wintery mix transitions to all rain by daybreak. Rain ends by the early morning hours and

Thursday – a second storm system moves through Wednesday night into Thursday, with high temperatures rising well into the mid-50s. Mostly cloudy skies will prevail.

Friday – more clouds than sun, with high temperatures dropping back a bit to about 50ºF.

NYC Nor’easter/Winter Storm Update – Jan 7, 2017

Overnight, forecast models shifted the track of the ongoing Nor’easter further west. This has implications for snowfall totals across the region.

Snowfall Totals

These have been bumped up for the city, which is now expected to receive 2-5″. The potential exists for more. Winter storm warnings now extend as far west as Nassau County, with points further east receiving as much as 7-12″.

As always with Nor’easters, even as they are ongoing, considerable uncertainty remains a factor. With these storms, one or more banding features will develop and circulate around the center of the storm as it progresses northeast. The number, extent, intensity, and western limit of advancement of these banding features ultimately determines what areas get the most snow. Within these bands, snowfall rates could easily reach 1-2″/hour. West of the western limit of the progression of these bands, snowfall totals will drop precipitously, such that a distance of 10 miles could mean the difference between 2″ and 6″+.

Timing

You can already see the radar signatures of two bands of moderate to heavy snow spawned by this storm. One of these bands is currently pushing its way west through Long Island, while another progresses towards shore. Within these bands, travel conditions will rapidly deteriorate while accumulations rack up.

Looking ahead to this afternoon, it would appear that the heaviest snow will fall in the city around 2PM, or the early afternoon.

The big weather news for the first full weekend of the new year is the deep Arctic chill that will be gripping the area. We should narrowly miss the core what would have been the first substantial Nor’easter of the season Saturday. The chill lasts through the beginning of next week when temperatures rebound back to above normal levels.

Rest of today – cold, with a mix of clouds and sun and a high temperature in the mid-30s. Wind chills in the low-20s.

Saturday – an uncertain scenario unfolds with the Nor’easter mentioned above. The one thing that is certain is that temperatures will be plenty cold to support all snow with highs only in the upper-20s. Two of the main forecast models continue to show a sizable spread in terms of how far east this storm tracks. This will ultimately determine whether portions west of Eastern Long Island see anything more than than a couple inches of snow. The cutoff between heavier snow and a light coating looks to be quite sharp also.

Sunday – overnight lows this weekend will be chilly, only in the upper-teens. Sunday, the wind picks up as the pressure gradient between the Nor’easter and high pressure building to the west increases. High temperatures will again only range in the upper-20s.

Monday – sunny, but still cold with a high temperature right around freezing.

Drought Update

Recent storms have brought beneficial rain and snow to the state and has helped alleviate some of the worst drought, while also staving off the redevelopment of drought in some areas. The cold temperatures have also been helpful in reducing evaporation from the soil. There’s almost no extreme drought left in the state, though most of Downstate remains in an area of severe drought.

NYC New Year’s Weather – Dec 30, 2016

A quick update here to give you all the weather for the upcoming New Years’ Eve celebrations this weekend. It should be a good night for festivities on Saturday, with only a slight chance for any precipitation. More substantial rains come Monday, cleansing us of the past year!

Rest of today – some widely scattered light snow showers are possible. Should be a mostly sunny day otherwise. Temperatures will be dropping to around 30ºF in the city overnight.

Saturday (New Year’s Eve) – partly sunny through the day but then mostly cloudy in the overnight hours as a weak storm system approaches from the west. This may bring a glancing shot at some rain showers overnight. High temperatures in the low-40s. Overnight lows should be not too chilly, in the upper-30s.

Sunday – New Year’s Day should see clouds decreasing, but clouds will increase again overnight as a more vigorous storm system approaches. High temperatures warm up a bit before this frontal boundary passes late on Monday, should top out in the mid-40s.

Monday – chance of a rain/snow mix in the city early in the day as temperatures will be cold enough, but this should transition to all rain by the afternoon hours with high temperatures in the mid-40s again.

We leave behind wild temperature swings that occurred the last few days as high pressure maintains steady and sunny conditions for most of this week. High temperatures should run just a few degrees above average, with some chance for passing showers on Thursday.

Rest of today – cold with below average high temperatures in the low-30s.

Tuesday – slightly warmer, but still below average with high temperatures in the upper-30s.

Wednesday – warmer with high temperatures in the mid-40s.

Thursday – a chance for showers as a weak storm system passes by, with a high again in the mid-40s and mostly cloudy skies.

Apologies for the lack of updates recently. Winter weather has come in full force a few days ahead of the actual Winter Solstice. We’ll see possibly record-tying or record-breaking cold Friday in some parts of the area, our first measurable snowfall in the city this season, all while temperatures swing about 30ºF from now through Sunday. The medium term shows a continuance of average to below-average temperatures in the upper-30s and low-40s.

Rest of today – we had some passing snow showers this morning, and there will be another chance for snow showers this afternoon. The main story will be the wind, cold temperatures, and low wind chills. A wind advisory is in effect for today with a high wind warning in place for tonight. Sustained winds of 20-30mph are expected, with wind gusts between 40mph to as high as 60mph possible later. Combined with high temperatures only in the mid-20s, this will result in wind chills of between 0-10ºF in the city.

Friday – slightly colder than today with highs in the mid-20s, with a very cold start to the morning as overnight lows drop into the teens. Winds will slowly abate through the course of the day as the high pressure center depicted above moves east over us, lessening the pressure gradient. Overnight Friday, a warm front approaches and brings the possibility for 1-2″ of snow.

Saturday – the snow will continue into the first half of Saturday with the possibility of 1-2″ additional inches of accumulation before temperatures warm and winds turn towards the southwest. There is some question as to whether some period of freezing rain will occur before a transition to all rain from south to north in the afternoon hours. High temperatures rebound nicely into the upper-40s in the wake of the warm front passing through.

Sunday – a cold front will follow the passage of the warm front mentioned above, but that shouldn’t happen until late Sunday. Ahead of that cold front passing, temperatures will continue to warm into the low-mid 50s as rain continues to fall. That snow won’t stick around long!

It’s the tale of two very different weather regimes this week. Starting the week, we have mild, rainy conditions accompanying a couple storm systems. This rain is still desperately needed as a drought continues to grip the area. Later in the week, things dry out, but temperatures also move in a downward trend back below normal.

Rest of today – mild with a high temperature near 60°F, rainy, with rain moderate to heavy at times. Rain tapering off by about 7PM this evening.

Wednesdaay – a complex set of of frontal boundaries move through the area tomorrow in association with a low pressure developing over the Great Lakes. In terms of sensible weather, expect a brief pause from the rain early Wednesday, but another round of overrunning rain that could then lead to a line of stronger storms with gusty winds late in the day as the cold front pictured below pushes through. Mostly cloudy with high temperatures again around 60°F.

Thursday – becoming sunny with high temperatures still holding up in the upper-50s.

Friday – cooler with high temperatures dropping to around normal in the low-50s with sun and clouds.

Drought Still Not Abating

Despite plenty of rain recently, large deficits built up from earlier in the year are still hard to beat, with many areas still in a moderate to severe drought in the NYC region.
